Description

Brown's Gas Generator {BROWN GAS GENERATOR}

The present invention relates to a Brown gas generator.

Brown gas is a gas obtained by electrolysis of water and is a mixed gas in which the content ratio of hydrogen and oxygen is 2: 1. Usually, when water is electrolyzed, hydrogen is obtained at the cathode and oxygen is obtained at the anode. Brown gas is collected at once without collecting these gases separately.

Brown gas, unlike ordinary gases, has a unique property of causing implosion on combustion. In other words, it does not show an explosion phenomenon during combustion, but rather a flame gathers inside to form a focal point and vacuum the surroundings.

As a result, the combustion of Brown gas yields an ultra-high temperature enough to sublimate tungsten, which has the highest melting point.

In addition, there is no energy loss due to radiant heat because the hot wire is not emitted to the outside, and has excellent energy efficiency, and since oxygen is included in itself, no separate oxygen supply is required during combustion. In addition, since only water is produced as a combustion product, there is no pollution problem.

Because of the above advantages, the Brown gas generator has been steadily improved in performance and safety and is used throughout the industry.

According to the Korean Utility Model Publication (Registration No .: 20-203926 (Registration date 2000.09.08)), each component of the electrolytic cell of the conventional Brown gas generator is shown in Figure 1, a plurality of inside the outer cylinder 320 The inner cylinder 330a is fixed to the upper and lower fixing plates 310a and 310b made of an insulator. At this time, the inner cylinder 330a functions as an electrode. Preferably, the inner cylinder 330a is plated by nickel plating on the surface of the mild steel by an electroless method, and the shape thereof can be varied into a cylinder, a square cylinder, or a polygonal cylinder.

The electrolyte is filled with an electrolyte prepared by mixing water and an electrolyte (potassium hydroxide (KOH)). The center rod 330, the upright cylinders 330a, and the outermost cylindrical body 320 are connected to the upper and lower fixing plates 310a and 310b of the insulating material, and thus the center rod 330 is insulated from each other and electrolyte is filled between the members. A current is applied to the 330 and the outermost upright cylinder 320 so that the upright cylinder 330a is alternately set to a positive electrode (+) and a negative electrode (−).

As described above, by generating an alternating induction current in the plurality of upright cylinders 330a, oxygen and hydrogen are generated, and brown gas is generated by mixing oxygen and hydrogen. When the brown gas is generated by electrolysis in the electrolytic cell, heat is inevitably generated by the electric current. When the temperature in the electrolytic cell is 50 to 60 ° C., the brown gas is produced at the maximum. The amount of gas produced is significantly reduced. Therefore, when the temperature in the electrolytic cell rises above a certain temperature during the generation of brown gas, the temperature of the electrolytic solution in the electrolytic cell needs to be cooled.

In order to cool the temperature of the electrolyte in the electrolytic cell, as shown in FIG. 1, a fin having a large heat dissipation area is formed while contacting the outer circumferential surface of the outer cylinder, and the fin is brought into contact with cold air by using a fan. By cooling, the electrolyte solution in contact with the cooled outer cylinder was cooled.

As described above, when the electrolytic cell is cooled by air cooling, first, the outer cylinder in contact with the fin is cooled by cold air, and the electrolyte is cooled by interfacial contact with the inner circumferential surface of the cooled outer cylinder, thereby lowering the cooling performance according to the cooling time delay.

As a result, the reduction in cooling performance is difficult to maintain the temperature in the electrolytic cell at the optimum brown gas generation temperature of 50 ~ 60 ℃, brown gas production capacity is low.

In addition, the electrolytic cell (electrolytic plate) has been enlarged by the cylindrical, flat plate or polygonal electrolytic area, but there is a limit to the widened electrolytic area with the cylinder, flat plate or polygonal.

In addition, the electrolyte is electrolyzed only between the respective inner cylinders 330a facing each other in the electrolytic cell to generate brown gas. The electrolyte is not independently present between the respective inner cylinders 330a, but a plurality of inner cylinders ( 330a) are all filled to be conductive.

Therefore, voltage is applied and current flows between the non-corresponding inner cylinders 330a irrespective of generating Brown gas, resulting in electrical loss, thereby increasing the gas generation efficiency compared to the voltage provided from the outside. There is a downside to falling.

The present invention was created in order to solve the above problems, each part of the electrolysis of the electrolytic solution in the electrolytic cell is present independently, and the water supply and water cooling to the independent portion is made separately, It is an object of the present invention to provide a brown gas generator that not only maintains the temperature optimally but also maximizes brown gas generating efficiency.

In addition, since the electrolyte is provided and circulated independently in each unit, the optimum temperature at which brown gas is generated is maintained. The water contained in brown gas is cooled by cooling brown gas collected through a water barrier and a multi-stage demister. Since it is removed, there is an advantage to obtain a purer brown gas.

In addition, since the water level sensor exists in the same space as the electrolytic cell, there is an advantage that can accurately determine the change in the water level due to the temporary pressure change in the electrolytic cell.

Hereinafter, with reference to the accompanying drawings will be described embodiments of the present invention;

2 is a configuration diagram of a brown gas generator according to the present invention, Figure 3 is a side cross-sectional view of the electrolytic cell of the brown gas generator according to the present invention.

Referring to the configuration of the brown gas generator according to the present invention with reference to Figures 2 and 3, the brown gas generator is filled with an electrolyte consisting of water and an electrolyte (potassium hydroxide (KOH)), the plate-shaped electrode plate 20 And the insulating plate 18 are fastened by the intermediate fixing plate 32 and circulate the electrolytic cell 12 which generates Brown gas by alternating induction current between the plate-shaped electrode plates 20, and the electrolyte solution of the electrolytic cell 12. To the circulation pump 24 for supplying water, the metering pump 26 for supplying water, and the heat exchanger 28 for heat-exchanging and circulating back into the electrolytic cell 12 after the electrolyte flowing into the cooling unit is cooled. And the electrolyte adjusting unit 16 for replenishing the insufficient electrolyte and cooling the heat exchanger 28 to a constant temperature when the electrolyte in the electrolytic cell is heat exchanged through the heat exchanger 28. Also it includes a cooling section 14 to self-cool.

Hereinafter, the configuration of the electrolytic cell 12 will be described in more detail.

Inside the electrolytic cell 12, a plurality of plate-shaped electrode plates fastened at regular intervals to a lower fixing plate 34, an intermediate fixing plate 32, an upper side of the lower fixing plate 34, and a lower side of the intermediate fixing plate 34 ( 20), a plurality of insulating plates 18 fastened at the same interval as the interval between the plate-shaped electrode plate is fastened to the upper side of the intermediate fixing plate 34.

In addition, a multi-stage demister 30 for collecting the generated gas is provided on the electrolytic cell 12, and a water barrier 44 between the electrolytic cell 12 and the demister 32. Is formed, and a gas discharge port 46 is provided at the top of the demister 32.

In addition, a pressure sensor 38 is attached to the outside of the side surface of the electrolytic cell 12, and a water level sensor 36 is built into a predetermined space inside the electrolytic cell case 42 on a surface adjacent to the side of the electrolytic cell 12. The outer side of the electrolytic cell 12 and the outer side of the side facing the electrolytic device 40 penetrating the electrolytic cell case 42 is present.

Hereinafter will be described in more detail the operation of the Brown gas generator according to the present invention as described.

The intermediate fixing plate 32 and the lower fixing plate 34 are made of an insulator, and the plate-shaped electrode plate functions as an electrode. Preferably, the middle fixing plate 32 and the lower fixing plate 34 are made of nickel plated on a mild steel surface by an electroless method. It is made of insulator.

In addition, the plurality of plate-shaped electrode plates 20 and the plurality of insulating plates 18 are fastened to the lower portion and the upper portion of the intermediate fixing plate 34 at equal intervals, respectively, the plate-shaped electrode plates 20 and the insulating plate facing each other. 18 constitutes a unit that produces Brown gas.

In detail, each of the plate-shaped electrode plates 20 facing each other is alternately set to a positive electrode (+) and a negative electrode (−) by a voltage applied to the electric drawing device 40 penetrating the side surface of the electrolytic cell 12. , Electrolyzing the electrolyte filled therebetween to produce Brown gas.

At this time, the electrolyte filled in the electrolytic cell must maintain a higher water level than the uppermost end of the plate-shaped electrode plate, that is, the lower side of the intermediate fixing plate 32.

According to the related art, in this case, voltage is applied and current flows through the electrolytic solution which is conducted between the plate electrodes, which are not related to the generation of Brown gas, resulting in electrical loss, thereby providing externally. Compared with the voltage, the gas generation efficiency was inferior.

In the electrolytic cell 12 according to the present invention for overcoming this, even if the electrolyte level is maintained higher than the top end of the plate-shaped electrode plate 20 to the intermediate fixing portion 34 at the same interval as the plate-shaped electrode plate 20. Electrolyte is prevented from conducting to the plate-shaped electrode plate 20 which is not supported by the insulating plate being fastened.

Here, the intermediate fixing part 34 has a hole between the plate-shaped electrode plate 20 and the insulating plate 18 which are fastened at regular intervals to form the unitary plate plate 20 and the insulating plate 18. Above and below the intermediate fixing part 34, the electrolyte is conducted.

Therefore, the plate-shaped electrode plate 20 corresponding to the applied voltage can efficiently generate brown gas by electrolyzing the electrolyte solution between the corresponding plate-shaped electrode plates 20 without electric loss.

In addition, the height of the insulating plate 18 is sufficiently high in consideration of the volume expansion of the electrolyte solution heated by electrolysis and the rise of the level of the electrolyte solution due to the pressure increase.

The most suitable temperature for generating Brown gas is, as is known, when the temperature of the electrolyte solution in the electrolytic cell 12 is about 50 to 60 ° C. However, if the temperature of the electrolytic cell 12 is not generated due to high heat during the electrolysis process and does not provide proper cooling, the amount of brown gas generated is significantly reduced.

Therefore, in the present invention, the cooling unit 14 is configured on one side of the electrolytic cell 12, and the electrolyte in the electrolytic cell 12 is circulated to the heat exchanger 28 so that the heat is transferred by the cooling unit 14. Cooling the exchanger 28 consequently cools the temperature of the electrolyte so that the temperature in the electrolytic cell 12 can always be kept constant.

The electrolytic solution controller 16 having such a role includes the circulation pump for circulating the electrolyte in the electrolytic cell 12 and the electrolyte pump introduced into the metering pump 26 and the cooling unit 14 to supply water. And the heat exchanger 28 which is then cooled and then heat exchanged to circulate back into the electrolytic cell 12.

In addition, the providing and circulating of the electrolyte in the electrolytic cell 12 may be performed independently of the plate-shaped electrode plate 20 and the insulating plate 18 forming each unit, and the supply and circulation of the electrolyte may be performed by the insulating plate 18. ) May be introduced into the plate-shaped electrode plate 20 or may be introduced into the plate-shaped electrode plate 20 and discharged to the insulating plate 18.

Figure 4 shows the demister installed on top of the electrolytic cell of the brown gas generator according to the present invention.

Referring to FIG. 4, the demister installed in the upper part of the electrolytic cell will be described. In the past, the demister 30 was installed in each electrolytic cell 12. However, in the present invention, as shown in FIG. The demister 30 capable of collecting all the brown gas generated in the electrolytic cell 12 in one place is provided at the upper portion of the 12.

Brown gas collected in the demister 30 adversely affects the characteristics of the brown gas when water is included, so as shown in FIG. 3, between the demister 30 and the upper portion of the electrolytic cell 12. A water barrier 44 is formed in multiple layers to prevent water from splashing out of the electrolytic cell 12.

A plurality of holes are formed in the water barrier film 44 to allow Brown gas to flow out into the demister 30 through the holes, and the positions of the holes formed in each of the water barrier films 44 are up and down. Do not overlap with the position of the hole formed in the water barrier film 44 that is opposite to prevent the water from splashing even in one place. In the above, the water barrier layer 44 may be formed to have several layers, but the splash of water may be minimized. However, if there are too many layers, the outflow path of Brown gas is difficult to be collected and thus, it should be manufactured in consideration of this.

In addition, the demister 30 has a multi-stage structure, and each demister 30 has a structure that cools the brown gas in itself, so that the moisture contained in the brown gas is removed and thus pure brown. The gas is collected, and the brown gas discharged from the gas discharge port 46 may be finally passed through a cooling device to obtain pure brown gas.

In addition, since the evaporated steam cooled in the demister 30 is returned to the inside of the electrolytic cell 12 again, it serves to prevent the temperature rise of the electrolyte in the electrolytic cell 12.

5 is a cross-sectional view of the interior of the electrolytic cell including a water level sensor of the brown gas generator according to the present invention.

Referring to FIG. 5, the inside of an electrolytic cell including a water level sensor, the conventional Brown gas generator is mounted on the outside of the electrolytic cell case and equipped with a level gauge that penetrates a part of the electrolytic cell case to maintain the same level as the level inside the electrolyzer. Although a water level sensor is attached to the inside, in this case, due to a temporary pressure change inside the electrolyzer, the pressure in the electrolyzer and the pressure of the externally mounted water level gauge may not match for a while.

As a result, the level sensor mounted to maintain the level of the electrolyte above the top of the plate-plate is insufficient.

In the Brown gas generator according to the present invention, a constant space is provided inside the electrolytic cell case 42 to maintain the same space as the inside of the electrolytic cell 12, and the water level sensor 36 is attached to the constant space. .

The predetermined space refers to a predetermined space provided inside the electrolytic cell case 42 with the uppermost end of the plate-shaped electrode plate 20 being the lowest point and the constant height of the insulating plate 18 being the highest point.

As a result, the space in which the water level sensor 36 is attached and the inside of the electrolytic cell 12 share the same space, and the pressure is the same, so that the water level sensor 36 can always accurately determine the water level in the electrolytic cell 12. It becomes possible.

In addition, the electrolytic cell case 42 is made of an insulator, and is not affected by the voltage or current inside the electrolytic cell 12 outside the electrolytic cell 12.

The pressure sensor 38 determines the pressure inside the electrolytic cell 12 and, when exceeding a predetermined pressure, signals the gas control unit 50 to stop supplying electricity to the electrolytic cell 12, If the pressure falls below the supply of electricity, the brown gas is generated.

As described above, according to the Brown gas generator according to the present invention, each of the corresponding plate-shaped electrode plates and the insulating plates are formed in one unit, and brown gas is generated independently of each other without being affected by other units. As an advantage, brown gas is generated.

In addition, since the electrolyte is provided and circulated independently in each unit, there is an advantage of maintaining the optimum temperature at which the brown gas is generated.

In addition, by cooling the collected brown gas through a water barrier and multi-stage demisters to remove moisture contained in the brown gas has the advantage of obtaining a more pure brown gas.

In addition, since the water level sensor exists in the same space as the electrolytic cell, there is an advantage that can accurately determine the change in the water level due to the temporary pressure change in the electrolytic cell.
