[27] Exemplary embodiments of the present invention will be described and illustrated in detail with reference to accompanying drawings.
[28] FIG. 1 is a block diagram showing the schematic configuration of an ratio controlling apparatus of generating oxygen/hydrogen mixed gas in accordance with the present invention, and FIG. 2 is a cross sectional view of the electrolytic cell in accordance with the present invention. Referring to FIG. 2, an electrolytic cell 10 of the present invention includes a container unit 11 to keep electrolyte therein, and an opening 12 at one end, to which a cover plate 13 is mounted.
[29] In the electrolytic cell 10, there are a plurality of electrodes 15 and a plurality of electrode plates 14, connected with the electrodes 15 to electrolyze the electrolyte by current supplied via the electrodes 15. When electric power is applied to the electrode plates 14 installed inside the electrolytic cell 10, oxygen/hydrogen gas is generated as air-bubbles on the surface of the electrode plates 14 by the electrolysis of the electrolyte contained inside the electrolytic cell 10.
[30] And an air-bubble dispersion device 16 is installed at the bottom of the electrolytic cell 10.
[31] An air supplying unit 30 is installed on one side of the electrolytic cell 10 constructed in this manner and is connected with the air-bubble dispersion device 16 installed inside the electrolytic cell 10 via an air supplying hose 17.
[32] The air supplying unit 30 can produce air and be constructed with an air compressor
(not shown).
[33] In the air supplying unit 30, an air-bubble injection pressure control unit 32 is installed in order to control the injection pressure of air, which is supplied to the air- bubble dispersion device 16 via the air supplying hose 17. In one side of the air-bubble injection pressure control unit 32, an air supplying unit 34 is installed to supply various types of air pressure to the air-bubble dispersion device 16 via the air supplying hose 17 by the signal of the air-bubble injection pressure control unit 32.
[34] Further, in other sides of the air-bubble injection pressure control unit 32, a composition ratio regulating unit 36 is formed to regulate the composition ratio of the
air supplied to the air supply unit 34, and a microprocessor unit 28 is connected with the air-bubble injection pressure control unit 32 and the composition ratio regulating unit 36 to control the air pressure and the composition ratio of the mixed gas.
[35] The microprocessor unit 38 controls both the air-bubble injection pressure control unit 32 and the composition ratio regulating unit 36 so that the air pressure of the supplied air and the composition ratio of the mixed gas correspond to a predetermined composition ratio.
[36] Besides, a volume/component detecting device 40 is formed on the side of a mixed gas output port 18 of the electrolytic cell 10 and works in connection with the air supplying unit 30.
[37] The volume/component detecting device 40 formed on the side of the mixed gas output port 18 sends out data regarding detected amount and composition ratio of the gas, which is generated from the electrolytic cell 10 and moving out through the mixed gas output port 18, to the microprocessor unit 38.
[38] An instruction signal is sent to the air-bubble injection pressure control unit 32 so that the data regarding the volume and composition ratio of the gas, transmitted to and received by the microprocessor unit 38 can be compared and set to be identical with the composition ratio, which is predetermined in microprocessor unit 38, and thereby, the pressure of the air supplied the air supplying unit 34 is controlled so as to eject the predetermined composition ratio of the oxygen/hydrogen gas through the mixed gas output port 18. Accordingly, it is possible to obtaining various composition ratios of oxygen/hydrogen mixed gas produced by electrolysis, corresponding to the combustion characteristics of Brown gas.
[39] With the temperature rise of the electrolyte of the electrolytic cell 10 lowered, electric power consumption is reduced by decreasing the number of times of operating the cooling unit of the oxygen/hydrogen gas generator, nitrogen oxides (NOx) generated from combustion are reduced, and the production of the oxygen/hydrogen gas from the electrolytic cell 10 also can be increased by preventing the hydrogen polarization phenomenon.
