POLLUTION CONTROL
Abstract
A quartz or pyrex tube has a plurality of windings disposed side
by side in insulated spaced relationship on the outside of the
tube. Oxides, sulphides and carbides of gases are passed through
the tube. Each winding is coupled to a generator of different
frequency. Each frequency is chosen to cause a corresponding gas to
decompose or break down. Harmless gases are vented to the
atmosphere and other elements are collected as disposable
solids.

Claims
Having thus described the invention, what is asserted as new
is:
1. Apparatus for selectively decomposing polluting exhaust gases of
a vehicle engine into harmless gases which may be safely vented to
the atmopshere or into disposable solids comprising:
a hollow tube which is adapted to be joined to an exhaust pipe of
an engine,
a plurality of windings of electric coils, each mounted outside the
tube, with said coil windings mounted side by side along the length
of the tube,
means individually coupled to each coil winding to supply a
selected high frequency electric signal to each coil, with each
coil supplied by a different frequency of signal of a magnitude to
cause decomposition of a particular component of the exhaust gas so
that selected components of the exhaust gases may be individually
decomposed as desired,
said hollow tube being vented at its outlet to the atmosphere, and
said outlet tube being formed of an electrical insulating
material.
2. The combination as recited in claim 1 in which said tube is
formed of quartz.
3. The combination as recited in claim 1 in which said tube is
formed of high-temperature resistant glass.
Description
FIELD OF THE INVENTION
Polluting gases, in accordance with my invention, as for example
various oxides of nitrogen, carbides, hydrocarbons, sulphides and
the like, are broken down to form oxygen, nitrogen, hydrogen,
carbon sulfur and the like. Harmless gases are released to the
atmosphere and other elements are collected as disposable
solids.
SUMMARY
To this end, a mixture of polluting gases as contained for example
in exhuast gases of vehicles and heating units are passed through
pyrex or quartz tubes. Windings insulatedly spaced from each other
are disposed side by side and are wound about the outside of the
tube. Each winding is excited by a different high frequency signal.
The frequencies are selected to each cause a different selected gas
to decompose or break down into its constituent parts which can
then be dealt with as indicated.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings:
FIG. 1 is a perspective view of generating equipment used in my
invention;
FIG. 2 is a perspective view of my invention as used in an
automobile; and
FIG. 3 is a perspective view of my invention as used with a
smokestack.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Referring first to FIG. 1, a quartz tube 10 has a thermocouple 12
disposed in one end which activates meter 14 to register
temperature. An oxide gas or carbide gas released from tank 16
passes through the tube. A winding 18 disposed around the outside
of the tube is coupled to signal generator 20. This high frequency
generator can be manually adjusted to any frequency within a
selected range. At some selected frequency, which varies with the
specific gaseous compounds, the spectrum of the gaseous compound
will be interfered with and its characteristics changed, causing it
to break down into original elements. When the gaseous compound
breaks down, heat will be absorbed from the hot exhaust of the
motor equal to that given off when the compound was formed.
In FIG. 2, the tube 10 (which can be pyrex or quartz) is disposed
in the exhaust pipe or a vehicle. Typically, this tube is
essentially the same diameter as the pipe in which it is sealed,
and is about twelve to sixteen inches long. About the tube is
disposed side by side a plurality of windings 18, these windings
being separated from each other by a ridge 24 in the glass. Each
coil is connected to a separate generating unit 20 powered by the
battery 26 of the vehicle and tuned to a different frequency.
The five units shown are tuned to break down a corresponding one of
five different gases, carbon monoxide, various oxides of nitrogen
(the oxide, dioxide and trioxide) and hydrocarbons. These gases are
pollutants. After the gases have been broken down, the oxygen,
hydrogen and nitrogen are released as harmless gases to the
atmosphere and carbon is precipitated as a powder which can be
removed and disposed of.
In FIG. 3, the exhaust gases in a commercial smoke stack are passed
through tube sections carrying windings 18. Interposed between
adjacent windings and sections in the path of the gas stream are
collection chambers 22. First monoxides of carbon are broken down
and the gases are passed through a dust collection chamber to
collect free carbon and ash. Sulfur dioxide gas is then decomposed
to oxygen and sulfur, and the sulfur is collected as powder in a
second chamber. The various oxides of nitrogen are broken down and
the harmless gases can then be released to the atmopshere. In this
manner, industrial pollution is reduced.
While I have described my invention with particular reference to
the drawings, such is not to be considered as limiting its actual
scope.
