Definitions
- the present invention relates to a Brown's gas generator, and more particularly, to a Brown's gas generator with a structure in which Brown's gas is independently generated therewithin, thereby improving generation efficiency of Brown's gas.
- Brown's gas is a gas obtained by electrolysis of water and a mixed gas of hydrogen and oxygen in the ratio of 2:1. Generally, if water is electrolyzed, hydrogen and oxygen are generated in a negative pole and a positive pole, respectively. At this time, Brown's gas can be obtained by simultaneously collecting the two gases, not by separately collecting them.
- Brown's gas Unlike general gases, Brown's gas has a peculiar property that causes an implosion phenomenon during the combustion thereof. In other words, an explosion phenomenon does not occur during the combustion of Brown's gas. Instead, flames are inwardly gathered to thereby form a focus and make surroundings vacuous.

Consequently, the cooling performance is degraded due to the delay of the cooling time. Therefore, the productivity of Brown's gas is degraded because it is difficult to maintain the electrolytic cell at the optimal temperature (50° to 60°) when generating Brown's gas.
- the electrolytic cell (an electrolytic plate) has been formed in a cylinder shape, a flat-panel shape or a polygonal shape so as to widen the electrolytic area, there is still a limitation on the widening of the electrolytic area.
- the electrolyte is electrolyzed only between the respective inner tubs 330 a facing each other, thus generating Brown's gas.
- the electrolyte exists independently between the respective inner tubs 330 a and it is also replete enough to make all the inner tubs 330 a electrified. Therefore, a voltage is also applied between the inner tubs 330 a having no relation to the generation of Brown's gas so that a current flows through them. As a result, an electric loss is incurred.
- the conventional Brown's gas generator has a disadvantage that degrades the efficiency of gas generation considering the voltage applied from an exterior.

Description
- This application is a continuation of PCT Application No. PCT/KR02/01794, filed on Sep. 23, 2002, and titled “Brown's Gas Generator,” which claims priority from Korean Patent Application No. 10-2002-0006146 filed on Feb. 4, 2002, and titled “Brown's Gas Generator,” the entire contents of which are hereby incorporated by reference.
- The present invention relates to a Brown's gas generator, and more particularly, to a Brown's gas generator with a structure in which Brown's gas is independently generated therewithin, thereby improving generation efficiency of Brown's gas.
- Brown's gas is a gas obtained by electrolysis of water and a mixed gas of hydrogen and oxygen in the ratio of 2:1. Generally, if water is electrolyzed, hydrogen and oxygen are generated in a negative pole and a positive pole, respectively. At this time, Brown's gas can be obtained by simultaneously collecting the two gases, not by separately collecting them.
- Unlike general gases, Brown's gas has a peculiar property that causes an implosion phenomenon during the combustion thereof. In other words, an explosion phenomenon does not occur during the combustion of Brown's gas. Instead, flames are inwardly gathered to thereby form a focus and make surroundings vacuous.
- As a result, if Brown's gas is burnt, it is possible to obtain an ultrahigh temperature at which even tungsten having the highest melting point can be sublimated.
- Additionally, since thermic rays are not radiated outwardly, there is no loss of energy, which is caused by a radiant heat, thus obtaining excellent energy efficiency.
- An additional oxygen supply is unnecessary during the combustion of Brown's gas since Brown's gas itself contains oxygen. Further, there is no pollution problem since only water is generated as combustion products.
- Because of the above-described merits, Brown's gas generators have been incessantly improved in performance and safety and are widely used.
-
FIG. 1 is a view schematically showing an electrolytic cell of a conventional Brown's gas generator. - Hereinafter, the electrolytic cell of the conventional Brown's generator will be described with reference to
FIG. 1 . - Korean Utility Registration No. 20-203926, issued on Sep. 8, 2000, discloses the electrolytic cell of the Brown's gas generator, in which a plurality of
inner tubs 330 a are fixed within anouter tub 320 by upper andlower fixing plates - Here, the
inner tubs 330 a function as electrodes and are preferably manufactured by plating a surface of mild steel with nickel in an electroless method. Also, theinner tubs 330 can be variously formed in a cylinder shape, a rectangular shape or a polygonal cylinder shape. - The electrolytic cell is filled with an electrolyte in which water and electrolyte (KOH) are mixed with each other. A
central rod 330, theinner tubs 330 a standing upright, and theouter tub 320 disposed at the outermost position are coupled to the upper andlower fixing plates inner tubs 330 a alternately set to a positive pole (+) and a negative pole (−) if a current is applied to both thecentral rod 330 and theouter tub 320. - As described above, due to a current alternately induced at the respective
inner tubs 330 a as the positive pole (+) and the negative pole (−), oxygen and hydrogen are generated and mixed with each other to thereby generate Brown's gas. - In such an electrolytic cell, heat caused by the current is inevitably generated when Brown's gas is generated using the electrolysis. When a temperature within the electrolytic cell is in the range of 50° to 60°, Brown's gas can be generated maximally. Meanwhile, if a temperature within the electrolytic cell is higher than 60°, the generation amount of Brown's gas is rapidly reduced.
- Therefore, if the temperature within the electrolytic cell is increased beyond a predetermined temperature when generating Brown's gas, a temperature of the electrolyte must be lowered.
- According to the related art, in order to lower the temperature of the electrolyte contained in the electrolytic cell, fins are provided, which are in contact with an outer periphery of the outer tub and have a wide heat radiation area, as shown in
FIG. 1 . By contacting the fins with a cool air using a fan, the outer tub is refrigerated and thus the electrolyte contacted with the refrigerated outer tub is also cooled. - However, in case that the electrolytic cell is refrigerated using the air-cooled method as described above, the outer tub contacted with the fin is primarily refrigerated due to the cool air, and the electrolyte is cooled by its interfacial contact with an inner periphery of the refrigerated outer tub. Consequently, the cooling performance is degraded due to the delay of the cooling time. Therefore, the productivity of Brown's gas is degraded because it is difficult to maintain the electrolytic cell at the optimal temperature (50° to 60°) when generating Brown's gas.
- Additionally, although the electrolytic cell (an electrolytic plate) has been formed in a cylinder shape, a flat-panel shape or a polygonal shape so as to widen the electrolytic area, there is still a limitation on the widening of the electrolytic area.
- Further, the electrolyte is electrolyzed only between the respective
inner tubs 330 a facing each other, thus generating Brown's gas. At this time, the electrolyte exists independently between the respectiveinner tubs 330 a and it is also replete enough to make all theinner tubs 330 a electrified. Therefore, a voltage is also applied between theinner tubs 330 a having no relation to the generation of Brown's gas so that a current flows through them. As a result, an electric loss is incurred. Accordingly, the conventional Brown's gas generator has a disadvantage that degrades the efficiency of gas generation considering the voltage applied from an exterior. - Accordingly, the present invention is directed to a Brown's gas generator that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
- An object of the present invention is to provide a Brown's gas generator, in which predetermined portions where an electrolysis of an electrolyte is performed are independently provided within an electrolytic cell and water supply and water cooling are individually carried out to the independent portions, thereby maintaining the temperature in the electrolytic cell at an optimal condition and maximizing the generation efficiency of Brown's gas.
- Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims thereof as well as the appended drawings.
- To achieve the object, there is provided a Brown's gas generator, which comprises: an electrolytic cell having a structure in which flat-type pole plates/insulating plates are coupled in pair with another flat-type pole plates/insulating plates, which are in interfacial contact with the flat-type pole plates/insulating plates, to thereby independently generate Brown's gas, the flat-type pole plates and the insulating plates being fixed at the same positions upward and downward around a middle fixing plate, the flat-type pole plates and the insulating plates being coupled at a regular interval by the middle fixing plate; an electrolyte adjustment means for circulating an electrolyte contained in the electrolytic cell to exchange heat of the electrolyte, and for replenishing a lack of the electrolyte; a refrigerating means for adjusting a temperature of the electrolyte by refrigerating a heat exchanger of the electrolyte adjustment means to a predetermined temperature when the heat of the electrolyte is exchanged; and a multi-stage demister installed in an upper portion of the electrolytic cell, for collecting Brown's gas in one place.
- The Brown's gas generator of the present invention has a structure in which the flat-type pole plate/insulating plate is coupled in pair with another flat-type pole plate/insulating plate, which is in interfacial contact with the flat-type pole plate/insulating plate, to thereby independently generate Brown's gas. In other words, since flat-type pole plate and corresponding insulating plate forms one unit to independently generate Brown's gas without being influenced by other units, Brown's gas can be efficiently generated without any electric loss. Additionally, because the electrolyte is independently supplied and circulated to the respective units, it is possible to maintain the optimal temperature for the generation of Brown's gas.

Agas exhaust hole 46 is installed in the uppermost portion of thedemister 30. - Further, a
pressure sensor 38 is attached to a lateral outside of theelectrolytic cell 12. A water level sensor (not shown) is internally installed in a predetermined space inside anelectrolytic cell case 42 adjacent to a lateral side of theelectrolytic cell 12. An electricity lead-inunit 40 passing through theelectrolytic cell case 42 is installed in a lateral side of theelectrolytic cell 12 and a lateral outside facing theelectrolytic cell 12. - An operation of the Brown's gas generator in accordance with the present invention will be described below in detail.
- The
middle fixing plate 32 and thelower fixing plate 34 are formed of an insulator. Preferably, the flat-type pole plate 20 functioning as an electrode is manufactured by a plating surface of mild steel with nickel in an electroless method. The insulatingplate 18 is formed of an insulator. - Additionally, the flat-
type pole plates 20 and the insulatingplates 18 are coupled to the lower and upper portions of themiddle fixing plate 32 at the same intervals. The flat-type pole plates 20 and the insulatingplates 18, which are in interfacial contact with each other, are coupled in pair and each pair form one unit as an independent structure that generates Brown's gas. - In other words, one flat-type pole plate/insulating plate is coupled in pair with corresponding flat-type pole plate/insulating plate, which is in contact with the flat-type pole plate/insulating plate, and the respective pairs independently generate Brown's gas.
- Describing the structure in detail, the flat-
type pole plates 20 facing each other alternately set to a positive pole (+) and a negative pole (−) due to a voltage applied to the electricity lead-inunit 40 passing through the lateral side of theelectrolytic cell 12, and the electrolyte filled between them is electrolyzed to thereby generate Brown's gas. - At this time, the electrolyte filled within the electrolytic cell must maintain a water level higher than the uppermost portion of the flat-type pole plate, i.e., the lower portion of the
middle fixing plate 32. - According to the related art, in that case, a voltage is applied due to the conductive electrolyte between the flat-type pole plates having no relation to the generation of Brown's gas so that a current flows through them. As a result, an electric loss is incurred. Accordingly, the conventional Brown's gas generator has a disadvantage that degrades the efficiency of gas generation considering the voltage applied from an exterior.
- In order to overcome the disadvantage of the related art, the
electrolytic cell 12 of the present invention makes the electrolyte not flow to the flat-type pole plates 20, which do not correspond to the insulating plates coupled to themiddle fixing plate 32 at the same intervals as the flat-type pole plates 20, even when the electrolyte maintains the water level higher than the uppermost portion of the flat-type pole plate 20. - Here, the
middle fixing plate 32 has holes between the flat-type pole plates 20 and the insulatingplates 18, which are coupled at regular intervals, so that the electrolyte flows up and down themiddle fixing plate 32 between the flat-type pole plates 20 and the insulatingplates 18, which are coupled in pair. - In other words, the electrolyte flows only in the independent structure in which the flat-type pole plate/insulating plate is coupled in pair with another flat-type pole plate/insulating plate, which is in interfacial contact with the flat-type pole/insulating plate, and the electrolyte does not flow in the flat-type pole plates that do not correspond to the insulating plates.
- Accordingly, due to the applied voltage, the corresponding flat-
type pole plates 20 electrolyze the electrolyte existing between them without any electric loss, thereby efficiently generating Brown's gas. - Additionally, considering that the water level of the electrolyte rises due to increases in volume and pressure of the electrolyte heated by the electrolysis, the insulating
plate 18 is manufactured high enough. - As is well known, when generating Brown's gas, the optimal temperature of the electrolyte contained in the
electrolytic cell 12 is about 50° to 60°. However, since theelectrolytic cell 12 generates a high-temperature heat during the electrolysis, if theelectrolytic cell 12 is not refrigerated, the generation amount of Brown's gas is rapidly reduced due to the rising temperature. - Accordingly, in the Brown's gas generator of the present invention, the refrigerating
unit 14 is installed in an outside of theelectrolytic cell 12. Also, the electrolyte contained in theelectrolytic cell 12 is circulated through theheat exchanger 28 so that theheat exchanger 28 is refrigerated. As a result, since the temperature of the electrolyte is lowered, the temperature of theelectrolytic cell 12 can be always maintained to a constant state. - The
electrolyte adjustment unit 16 performing the above function includes thecirculation pump 24 for circulating the electrolyte contained in theelectrolytic cell 12, the quantitative pump 26 for supplying water, and theheat exchanger 28 for performing a heat exchange after the electrolyte introduced into the refrigeratingunit 14 is cooled and circulating the electrolyte to theelectrolytic cell 12. - Additionally, the supply and circulation of the electrolyte contained in the
electrolytic cell 12 is independently performed between the flat-type pole plates 20 and the insulatingplates 18, which form the respective units. The electrolyte can be introduced into the insulatingplates 18 forming the units or discharged to the flat-panel plates 20. Alternatively, the electrolyte can be introduced into the flat-panel pole plates 20 or discharged to the insulatingplates 18. -
FIG. 4 is a view of the demister installed in an upper portion of the electrolytic cell of the Brown's gas generator in accordance with the present invention. - Hereinafter, the demister installed in the upper portion of the electrolytic cell will be described with reference to
FIG. 4 . In the related art, thedemisters 30 are installed in the respectiveelectrolytic cells 12. As shown inFIG. 4 , however, according to the present invention, thedemister 30 that can collect all Brown's gases generated in theelectrolytic cell 12 in one place is installed in an upper portion of theelectrolytic cell 12. - If Brown's gas collected by the
demister 30 contains water, a property of Brown's gas is badly influenced. Therefore, as shown inFIG. 3 , the multi-layeredwater prevention screen 14 for preventing a splash of water is formed between thedemister 30 and the upper portion of theelectrolytic cell 12. - A plurality of holes are formed in the
water prevention screen 14, and Brown's gas is discharged to the demister through the holes. Positions of the holes formed in the respectivewater prevention screen 44 are not overlapped with those formed in thewater prevention screen 44 facing each other upward and downward. Therefore, water is not splashed at any place. If thewater prevention screen 44 is formed in more layers, the splash of water can be minimized. However, if thewater prevention screen 44 is formed in too many layers, the passage of Brown's gas is obstructed so that it is difficult to collect Brown's gas. Therefore, thewater prevention screen 44 should be manufactured in consideration for that. - Further, since the
demister 30 has a multi-stage structure and also has a structure for refrigerating Brown's gas therewithin, moisture contained in Brown's gas is removed so that pure Brown's gas is collected. Since Brown's gas exhausted from thegas exhaust hole 46 finally passes through the refrigerating unit, pure Brown's gas can be obtained. - Furthermore, an evaporation steam cooled at the
demister 30 flows backward to theelectrolytic cell 12, thereby preventing an increase in the temperature of the electrolyte contained in theelectrolytic cell 12. -
FIG. 5 is a sectional view of the inside of the electrolytic cell including the water level sensor installed in the Brown's gas generator ofFIG. 2 , taken along the line B-B′. - Here, although
FIG. 5 is a sectional view of a predetermined portion of the electrolytic cell shown inFIG. 2 , taken along the line A-A′, the demister that is not shown inFIG. 2 is illustrated inFIG. 5 . - The inner structure of the electrolytic cell having the water level sensor will be described with reference to
FIG. 5 . - In the conventional Brown's gas generator, a water gauge passing through a portion of the electrolytic cell case to maintain the same water level as the inside of the electrolytic cell is installed on the outside of the electrolytic cell case, and the water level sensor is attached to the inside of the water gauge.
- However, due to a temporary pressure variation in the inside of the electrolytic cell, there occurs the case that the pressure in the inside of the electrolytic cell may not accord with that of the externally installed water gauge for a short time. As a result, the water level sensor installed so as to maintain the water level of the electrolyte beyond the uppermost portion of the flat-type pole plate does not sufficiently perform its own function.
- On the contrary, in the Brown's gas generator of the present invention, the same space as the inside of the
electrolytic cell 12 is maintained by providing a predetermined space inside theelectrolytic cell case 42, and thewater level sensor 36 is attached to the predetermined space. - The predetermined space is a space provided inside the
electrolytic cell case 42, where the uppermost portion of the flat-type pole plate 20 is the lowest point and a predetermined height of the insulatingplate 18 is the highest point. - Because the space where the
water level sensor 36 is attached and the inside of theelectrolytic cell 12 shares the same space and their pressures are equal to each other, thewater level sensor 36 can always correctly determine the water level of the inside of theelectrolytic cell 12. - Further, since the
electrolytic cell case 42 is formed of an insulator, the voltage or current of the inside of theelectrolytic cell 12 does not influence the outside of theelectrolytic cell 12. - The
pressure sensor 38 determines the internal pressure of theelectrolytic cell 12. If the internal pressure of theelectrolytic cell 12 is greater than a predetermined pressure, the electricity supplied to theelectrolytic cell 12 is cut off by applying a signal to agas control unit 50. Meanwhile if the internal pressure of theelectrolytic cell 12 is less than the predetermined pressure, the electricity is again supplied to theelectrolytic cell 12 to thereby generate Brown's gas. - As described above, the Brown's gas generator of the present invention has a structure in which the flat-type pole plate/insulating plate is coupled in pair with another flat-type pole plate/insulating plate, which is in interfacial contact with the flat-type pole plate/insulating plate, to thereby independently generate Brown's gas. In other words, since flat-type pole plates and corresponding insulating plates form one unit to independently generate Brown's gas without being influenced by other units, Brown's gas can be efficiently generated without any electric loss.
- Additionally, since the electrolyte is independently supplied and circulated to the respective units, it is possible to maintain the optimal temperature for the generation of Brown's gas.
- Further, since moisture contained in Brown's gas is removed by cooling Brown's gas collected by the water prevention screen and the multi-stage demister, it is possible to obtain pure Brown's gas.
- Furthermore, since the water level sensor is provided in the same space as the inside of the electrolytic cell, it is possible to correctly determine the variation of the water level according to the temporary pressure change in the inside of the electrolytic cell.
- While the present invention has been described and illustrated herein with reference to the preferred embodiments thereof, it will be apparent to those skilled in the art that various modifications and variations can be made therein without departing from the spirit and scope of the invention. Thus, it is intended that the present invention covers the modifications and variations of this invention that come within the scope of the appended claims and their equivalents.
