Description
[0001] This application is a continuation of International
Application No. PCT/KR2018/008261, filed on Jul. 23, 2018, which
claims priority to Korean Patent Application No. 10-2017-0108585,
filed on Aug. 28, 2017. The disclosures of the aforementioned
applications are hereby incorporated by reference in their
entireties.
FIELD
[0002] The present disclosure relates to an electrolysis apparatus
capable of producing a disinfectant or a cleaning agent and an
electrolysis method therefor, and more particularly, to an
apparatus and a method for producing a disinfectant or a cleaning
agent based on an additive added to electrolysis.
BACKGROUND
[0003] Sterilization refers to the process of killing or
eliminating germs within a short time by applying physical and
chemical stimuli to the germs. Sterilization may be divided into a
process of making an object completely free from germs and a
process of making an object almost free from germs according to how
much sterilization is performed.
[0004] Sterilization may be achieved by mechanical destruction of a
fungus body, strong denaturation of proteins, enzyme inactivation,
etc., and may include a physical method and a chemical method.
Physical sterilization provides a physical environment in which
germs are killed or eliminated by drying, sunning, emitting
ultraviolet rays, or irradiating a target object. Chemical
sterilization provides a chemical environment in which germs are
killed or eliminated by using a disinfectant, a sterilization gas,
etc.
[0005] Sterilization is for removing germs which are harmful to a
human body, and in the case of food, germs are removed by
cleaning.
[0006] If harmful germs remain, the germs may cause food poisoning
or waterborne diseases. That is, if germs causing waterborne
diseases and germs causing food poisoning remain on tableware, food
processing equipment, cooking equipment, production devices in a
food factory, mass feeding facilities, etc., the germs may cause
food poisoning and waterborne diseases. Therefore, in order to
prevent food poisoning and waterborne diseases, germs on tableware,
food processing equipment, cooking equipment, production devices in
a food factory, mass feeding facilities, etc., should be killed or
eliminated. Sterilization described above may mostly use the
physical and chemical methods, but there are problems that devices
and facilities for sterilization are required and it takes a long
time to sterilize.
[0007] Accordingly, a recent method uses sterilizing water in
replacement of cleaning water for cleaning various cooking
equipment easily, and performs cleaning and sterilization
simultaneously, thereby increasing sterilization efficiency. Since
food should be sterilized to ensure safety, disinfectants and
sterilizers are currently designated as managed objects under the
Food Sanitation Act.
[0008] Water normally supplied and used to clean may be sterilized
by using chlorine (Cl.sub.2). Chlorine may kill, eliminate or
inactivate germs by changing permeability of cell membranes of
germs. Chlorine is good in terms of residuality of a sterilizing
function and economic feasibility, and is widely used as a water
sterilizer.
[0009] However, it is known that trihalomethane (THM) which is a
carcinogen is generated due to a reaction of an organic compound of
source water sterilized with chlorine. In particular, the amount of
trihalomethane increases as the amount of supplied chlorine
increases. In addition, chlorine has unique odor and remains after
sterilization. Accordingly, there is a trend of reducing the amount
of chlorine used to sterilize in order to minimize generation of a
carcinogen and to prevent odor.
[0010] Accordingly, the sterilization effect may be reduced due to
the reduction in the amount of used chlorine, and, as the amount of
remaining chlorine is reduced, there is a high risk that germs
remaining in a pipe during the supply of water are not killed or
eliminated. Therefore, sterilizing water including a material
capable of sterilizing is used to enhance the sterilization effect.
The sterilizing water may sterilize contaminated materials or
cooking equipment used for food and food ingredients, and may kill
or eliminate germs which may cause food poisoning and waterborne
diseases, thereby enhancing safety.
[0011] Related-art sterilizing water is mostly used in a
sterilization method using sodium hypochlorite. Sodium hypochlorite
is used as a disinfectant to kill or eliminate putrefying bacteria
of food or pathogens, and is used for drinks, vegetables and
fruits, containers, equipment, tableware, etc. Sodium hypochlorite
dissolves easily in water and an aqueous solution thereof
decomposes during storage and generates chlorine gas. Therefore, if
sodium hypochlorite is stored for a long time, it is not effective
as a disinfectant. Sterilizing power may be influenced by a
hydrogen ion concentration (pH) and an amount of available
chlorine. Therefore, sterilizing power may increase if sterilizing
water is in an undissociated state and a hydrogen ion concentration
(pH) is low.
[0012] The sterilization method using sodium hypochlorite may
include a method of injecting sodium hypochlorite (NaOCl) which is
commercially available, and a method of directly generating sodium
hypochlorite by using electrolysis on the spot. To increase
sterilizing power, a large amount of sodium hypochlorite should be
used, and accordingly, a large facility is required to produce
sterilizing water. To reduce a production cost of sterilizing water
produced in the large production facility, a large amount of
sterilizing water should be produced by a single driving operation.
Therefore, there is a need for a device for storing and moving the
large amount of produced sterilizing water.
[0013] To solve these problems, a sterilization apparatus (U.S.
Pat. No. 789,325, U.S. Patent Publication No. 2004-013707) which
uses hypochlorous acid which is produced in small quantity during
electrolysis for producing sodium hypochlorite, and has high
sterilizing power is used.
[0014] In an electrolysis process for producing sodium hypochlorite
(NaOCL), hypochlorous acid (HOCL) is generated along with hydrogen
(H) and hypochlorite ion (OCL.sup.-). Hypochlorous acid has about
70 times sterilizing power of sodium hypochlorite. In addition,
hypochlorous acid has a big difference in sterilizing power
according to a hydrogen ion concentration (pH), and has the maximum
sterilizing power when pH is 4.3-5.9.
[0015] Accordingly, if sterilizing water is produced by using
hypochlorous acid, sterilizing water having high sterilizing power
is produced with a small amount of hypochlorous acid, and
accordingly, the size of a sterilizing water production apparatus
may be reduced. In addition, since it is easy to produce a small
amount of sterilizing water, sterilizing water may be produced
without any device for moving and storing.
[0016] However, since hypochlorous acid is produced in small
quantity and also is mixed with sodium hypochlorite which is
mass-produced, there may be a problem that it is difficult to
separate hypochlorous acid and sodium hypochlorite.
[0017] In addition, hypochlorous acid has a big difference in
sterilizing power according to a hydrogen ion concentration. That
is, if the hydrogen ion concentration falls out of the range of 4.3
to 5.9 having the maximum sterilizing power, hypochlorous acid has
so low sterilizing power that it may not be used as sterilizing
water.
[0018] Accordingly, there is a demand for researches on a method
for directly producing hypochlorous acid in a place where a
disinfectant is used such as home, making a hydrogen ion
concentration fall within a range having the maximum sterilizing
power, and producing hypochlorous acid by separating from sodium
hypochlorite.
SUMMARY
[0019] An object of the present disclosure is to solve the
above-described problems and other problems. Another object is to
provide an apparatus and a method for producing a disinfectant or a
cleaning agent by using a device producing hypochlorous acid.

DETAILED DESCRIPTION
[0032] Hereinafter, embodiments disclosed in the present disclosure
will be described in detail with reference to the accompanying
drawings. The same reference numerals are used for the same or
similar elements regardless of signs in the drawings, and a
redundant explanation thereof is omitted. The suffixes "module" and
"part" used for elements in the following description are given or
used interchangeably only in consideration of easy writing of
specification, and have no distinct meaning or role. In the
description of exemplary embodiment, certain detailed explanations
of related art are omitted when it is deemed that they may
unnecessarily obscure the essence of the embodiments disclosed in
the present disclosure. In addition, the accompanying drawings are
just for easy understanding of embodiments disclosed in the present
disclosure, and do not limit the technical concept disclosed in the
present disclosure. In addition, it should be understood that the
present disclosure includes all variations, equivalents, and
substitutes within the technical concept and the scope of the
present disclosure.
[0033] If the terms such as "first" and "second" are used to
describe elements, these elements should not be limited by such
terms. These terms are used for the purpose of distinguishing one
element from another element only.
[0034] In the following description, it will be understood that
when an element is referred to as being "coupled to" or "connected
to" another element, the element may be directly coupled or
connected to another element or there may be an intervening element
therebetween. On the other hand, it will be understood that when an
element is referred to as being "directly coupled to" or "directly
connected to" another element, there is no intervening element
therebetween.
[0035] The singular forms are intended to include the plural forms
as well, unless the context clearly indicates otherwise.
[0036] It will be further understood that the term "include" or
"have" used in the present application indicates the presence of
features, numbers, steps, operations, elements, and components
described in the specification, or a combination thereof, and do
not preclude the presence or addition of one or more other
features, numbers, steps, operations, elements, or components, or a
combination thereof.
[0037] Sodium hypochlorite is a colorless or pale greenish yellow
liquid, and has odor of chlorine. The formula is NaClO. Sodium
hypochlorite dissolves easily in water, and an aqueous solution
thereof decomposes during storage, thereby generating chlorine gas.
Therefore, if sodium hypochlorite is stored for a long time, sodium
hypochlorite is not effective as a disinfectant. Sterilizing power
is influenced by pH and an amount of available chlorine, and
accordingly, may increase when sodium hypochlorite is in an
undissociated state and pH is low, and the sterilizing power is
reduced by amino acid, protein, sugar, etc. The sterilizing power
is the greatest when sodium hypochlorite is diluted to have a
concentration of 100 ppm and pH is adjusted to 8-9. Sodium
hypochlorite is highly corrosive and thus should not contact a
metal container. To increase the sterilizing power, tableware
should be cleaned before sodium hypochlorite is used to sterilize
tableware. Sodium hypochlorite should be stored in a lightproof
glass container.
[0038] Hypochlorous acid (HClO) is used for water, fruits,
tableware, tofu, etc. as a disinfectant. Hypochlorous acid is
produced by distilling bleaching powder in a carbon dioxide
atmosphere, shaking a carbon tetrachloride solution of chlorine
dioxide with water simultaneously, or passing chlorine gas through
an aqueous solution of sodium bicarbonate at low temperature, and
has the feature of existing as an aqueous solution. A concentrated
solution of a highest concentration of 25% has a greenish yellow
color, and a dilute solution is colorless and has pungent odor
similar to that of bleaching powder. Hypochlorous acid is less
acidic than acetic acid, and an aqueous solution thereof is
unstable, discharges oxygen and decomposes, and generates
hydrochloric acid and chloric acid and shows strong oxidation. When
hypochlorous acid is stored at -20.degree. C., hypochlorous acid
may be stored for many days, but, when it is stored at room
temperature, it is not easier to store than sodium
hypochlorite.
[0039] In an electrolysis process for producing sodium hypochlorite
(NaOCL), hypochlorous acid (HOCL) is produced along with hydrogen
(H) and hypochlorite ion (OCL.sup.-) may also be generated.
Hypochlorous acid has about 70 times sterilizing power of sodium
hypochlorite. In addition, hypochlorous acid has a big difference
in sterilizing power according to a hydrogen ion concentration
(pH), and has the greatest sterilizing power when pH is
4.3-5.9.
[0040] The present disclosure suggests a method for generating
(producing hypochlorous acid in a home through electrolysis and
directly using the same. Therefore, even if it is not easy to store
hypochlorous acid, hypochlorous acid may be directly and easily
produced and used through the suggested method.
[0041] Furthermore, an embodiment of the present disclosure
suggests a method for producing hypochlorous acid or sodium
hypochlorite as a disinfectant, or producing potassium hydroxide as
a cleaning agent according to a kind of an additive added in an
electrolysis apparatus.
[0042] To achieve this, an embodiment of the present disclosure may
include a non-diaphragm electrolytic cell provided with an
electrode, and water containing chloride ions (Cl.sup.-), sodium
chloride (NaCl), and a hydrochloric acid aqueous solution (HCl) may
be electrolyzed on the non-diaphragm electrolytic cell.
[0043] In addition, an embodiment of the present disclosure may
further include an additive container to add an additive to the
electrolysis.
[0044] The additive container will be described in detail
below.
[0045] In an embodiment of the present disclosure, a selective
product may be obtained according to a kind of an additive, and
results of experiments therefor are attached as follows:
[0046] [Experiment Method 1]
[0047] 1) An additive was added to source water (tap water) of 500
ml (water containing chloride ions), non-diaphragm electrolysis was
performed for about 5 minutes, and then pH of a product was
measured.
[0048] 2) The experiment was conducted many times by changing a
ratio of salt water (NaCl) of 30% concentration and hydrochloric
acid (HCl) in the additive.

[0049] [Experiment Method 2]
[0050] 1) An additive was added to different amounts of source
water (tap water, water containing chloride ions) (500 ml, 1000
ml), non-diaphragm electrolysis was performed for about 5 minutes,
and then pH of a product was measured.
[0051] 2) The experiment was conducted many times after the

[0054] 2) The experiment was conducted many times by changing an
amount of potassium carbonate (K.sub.2CO.sub.3) aqueous solution of
the additive.

[0055] As a result of the experiments by the experiment methods 1
and 2, a hypochlorous acid solution (HOCl) was produced as a
product, and as a result of the experiments by the experiment
method 3, potassium hydroxide (KOH) was produced as a product.
[0056] According to the experiment methods 1 and 2, the following
reactions occur on respective (+) and (-) electrodes, and
hypochlorous acid is generated:

[0057] It is apparent that the hypochlorous acid solution may be
utilized as a disinfectant having very high sterilizing power as
described above, and potassium hydroxide may be used for various
purposes as a natural cleaning agent.
[0058] Therefore, the present disclosure suggests the apparatus and
the method for producing a cleaning agent or a disinfectant based
on the results of the experiments described above.
[0059] FIG. 1 is a concept view of an electrolysis apparatus 101
according to an embodiment of the present disclosure. FIG. 2 is a
flowchart of an electrolysis method according to an embodiment of
the present disclosure.
[0060] In an embodiment of the present disclosure, the electrolysis
apparatus 101 may include a non-diaphragm electrolytic cell 103 and
a container 102
[0061] An liquid storage part A 10 and a liquid storage part B 20
are integrally formed with a container main body 30 which is formed
with synthetic resin by molding, and a measuring cup 40 having the
volume scale displayed on a side surface thereof is disposed on an
upper portion of the container main body 30. Pumping tubes 11, 21
are coupled to both sides of the container main body 30 to pump
materials stored in the A liquid storage part 10 and the B liquid
storage part 20 into the measuring cup 40, and an opening and
closing lid 50 is removably coupled to an upper portion of the
measuring cup 40 by screwing.
[0062] FIG. 3 is a cross-sectional view of the measuring container
of the present disclosure, and FIG. 4 is a cross-sectional view of
the measuring cup of the present disclosure.
[0063] The discharge measuring container of the present disclosure
may contain different materials in the liquid storage part A 10 and
the liquid storage part B 20.
[0064] That is, in the electrolysis apparatus 10 according to an
embodiment of the present disclosure, a different product may be
produced according to a kind of an additive, and the liquid storage
part A 10 and the liquid storage part B 20 of the container 102 are
provided to contain different additives, respectively. Table 4
presented below shows examples of additives that may be separately
stored in the container 102 according to an embodiment of the
present disclosure.

Salt water (15%) Vinegar
[0065] When different additives are stored in the respective
storage parts 10, 20 according to the 1.sup.st to 4.sup.th
examples, a user may selectively add a desired additive, and also,
may mix the two additives at an exact ratio and may put the mixture
to the electrolysis.
[0066] A mixing ratio of additives according to an embodiment of
the present disclosure is important. This is because pH of a
desired level varies according to a user. For example, if a user
thinks that a disinfectant of low pH is effective and satisfies
his/her own using condition, the user may increase the amount of
second additive stored in the liquid storage part B 20 in the
1.sup.st or 2.sup.nd example.
[0067] pH may be changed according to a purpose. In this case,
there may be a need to change the mixing ratio of the additives
appropriately. For example, when a user wishes to sterilize a
bathroom, the user may mix additives to reduce pH to obtain higher
sterilizing power. To the contrary, if a user wishes to sterilize a
body such as a wound, the user should mix additives to reach pH
which is close to neutral pH and is effective.
[0068] When a user wishes to apply additives according to various
situations such as purposes or skin types, the user may exactly
measure additives separately stored in the liquid storage part A 10
and the liquid storage part B 20 of the container 102 according to
an embodiment of the present disclosure, and may easily add the
additives.
[0069] When the liquid storage part A 10 is pressed, the first
additive is pumped through the pumping tube 11 and a selected
amount of the first additive is contained in the measuring cup 40.
Each additive may be individually and independently used, or, by
pumping the second additive by pressing the B liquid storage part
20, the first and second additives may be mixed at a selected ratio
and may be used in the mixed state.
[0070] That is, the container 102 which may discharge and measure
materials according to the present disclosure may store different
kinds of materials, simultaneously, and may selectively use only a
specific material if necessary or may mix two or more materials at
a selected ratio and use the same, such that using convenience of a
product may be maximized.
[0071] In addition, when potassium hydroxide is used as the second
additive contained in the liquid storage part B 20 as in the
3.sup.rd and 4.sup.th examples, a disinfectant and a cleaning agent
may be selectively produced as described in the 1.sup.st to
3.sup.rd experiments.
[0072] FIGS. 5 and 6 illustrate a backflow prevention structure
according to another embodiment of the present disclosure. A
backflow prevention instrument 60 is provided in a connection part
with the pumping tube 11, 21 in the measuring cup 40. A net 61 is
disposed on a side surface of the measuring cup 40 to prevent the
backflow prevention instrument 60 from being released and to
prevent foreign substances from entering, and an inclined surface
62 inclining downward toward the pumping tube 11, 21 is formed in
the connection part with the pumping tube 11, 21 to maintain the
backflow prevention instrument 60 in contact with an outlet of the
pumping tube 11, 21.
[0073] In addition, a lubrication layer 62a may be coated on the
inclined surface 62 to prevent the backflow prevention instrument
60 from adhering and to prevent foreign substances from being
adsorbed, and it is preferable that the lubrication layer 62a is
formed with a mixture composition of 20-40 weight % of Teflon,
10-30 weight % of nano-silver, 10-20 weight % of methyl metacrylate
(MMA), 10-20 weight % of silica glass, 5-10 weight % of unsaturated
polyester resin, 1-5 weight % of oyster shell powder.
[0074] According to the structure as described above, the backflow
prevention instrument 60 usually blocks an inlet of the pumping
tube 11, 21 due to the presence of the inclined surface 62, and
opens by a pressure interaction only when the pumping tube is
pumped.
[0075] Accordingly, a liquid mixed in the measuring cup 40 may be
prevented from flowing back through the pumping tubes 11, 21 by the
backflow prevention instrument 60 during a discharge process.
[0076] Since the lubrication layer 62a is formed on the inclined
surface 62, the backflow prevention instrument 60 smoothly moves
and a problem caused by adsorption of foreign substances may be
solved. In particular, since oyster shell powder, methyl
metacrylate, and silica glass are added, the durability of the
lubrication layer 62a increases and a crack on the lubrication
layer 62a, which is caused by contact by the backflow prevention
instrument 60, may be prevented.
[0077] In addition, the unsaturated polyester resin increases
binding power of oyster shell powder and silica glass, such that
the lubrication layer 62a may be prevented from being peeled off in
part.
[0078] The electrolysis method according to an embodiment of the
present disclosure is explained by referring to FIG. 2. In process
S201, water containing chloride ions is put into the non-diaphragm
electrolytic cell 103.
[0079] Next, in process S202, the above-described additives may be
added. For example, a selected amount of a first additive in liquid
storage part A 10 and a selected amount of a second additive in
liquid storage part B 20 may be pumped to the measuring cup 40,
respectively, thereby making a selected amount of a mixed liquid.
And then, the mixed liquid of the additives is put into the
non-diaphragm electrolytic cell 103. A product obtained by
electrolysis and a pH value of the product may vary according to
the additive as described above.
[0080] In process 203, power is supplied to the electrode of the
non-diaphragm electrolytic cell 103, and electrolysis is performed
for producing a cleaning agent or a disinfectant.
[0081] While embodiments of the electrolysis method and the
electrolysis apparatus using the same according to the present
disclosure have been described, they may be described as at least
one embodiment, and the technical concept of the present disclosure
