The present invention relates to a brown gas generator, and more particularly to a forced circulation-cooled 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. That is, it does not show an explosion phenomenon during combustion, but rather, a flame gathers inside to form a focal point and vacuum the surroundings.

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.

1 is a schematic view showing an electrolytic cell of a brown gas generator according to the prior art. On the other hand, Figure 1 is only one example of the prior art, the following problem may occur in the Brown gas generator by another structure and method.

Referring to Figure 1, the electrolytic cell of the conventional Brown gas generator is as follows. As shown in FIG. 1, the components of the electrolytic cell of the brown gas generator according to the related art are fixed to the upper and lower fixing plates 31a and 31b made of an insulator in the inner cylinder 32. At this time, the inner cylinder 33a functions as an electrode.

The electrolyte is filled with an electrolyte prepared by mixing water and an electrolyte (potassium hydroxide (KOH) or sodium hydroxide (NaOH)). The center rod 33, the upright cylinders 33a, and the outermost cylinder body 32 are connected to the upper and lower fixing plates 31a and 31b of the insulating material, and are insulated from each other, but electrolyte is filled between each component. Therefore, a current is applied to the center rod 33 and the outermost upright cylinder 32 so that the upright cylinder 33a is alternately set as a positive electrode (+) and a negative electrode (−).

As described above, a plurality of upright cylinders 33a alternately generate currents induced in the positive electrode (+) and the negative electrode (−), whereby oxygen and hydrogen are generated to mix oxygen and hydrogen, thereby generating brown gas. When the brown gas is generated by electrolysis in the electrolytic cell, heat is inevitably generated when the brown gas is generated by electrolysis. 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, a fin (not shown) having a large heat dissipation area is formed while being in contact with the outer circumferential surface of the outer cylinder, and the fin is brought into contact with cold air by using a fan (not shown). By cooling, the electrolyte solution in contact with the cooled outer cylinder was cooled.

However, when the electrolytic cell is cooled by air in the prior art as described above, the outer cylinder contacted with the fin is first cooled by cold air, and the electrolyte is cooled by interfacial contact with the inner circumferential surface of the cooled outer cylinder. The lowering of the cooling performance is difficult to maintain the temperature in the electrolytic cell at 50 ~ 60 ℃, the optimum brown gas generation temperature, there is a problem that the brown gas production capacity is reduced.

In addition, according to the prior art, the electrolytic cell (electrolytic plate) is made of a cylinder, a plate or a polygon, etc., to increase the electrolytic area, but there is a limit to the electrolytic area of the cylinder, the plate, or a polygon.

On the other hand, in the case of generating a large amount of brown gas using a plurality of electrolytic cells in the brown gas generator according to the prior art, water hammering occurs in which noise and vibration occur in the electrolytic cell due to an uneven supply of electrolyte. Due to such water hammering, there was a problem that a hunting phenomenon occurs in which a pressure difference rapidly occurs depending on the level of the electrolyzer.

In addition, according to the prior art, when the electrolytic solution of the electrolytic cell is electrolyzed to Brown gas, the amount of water decreases, and there is a problem in that a hunting phenomenon occurs in which a pressure difference rapidly occurs depending on the level of the electrolytic cell.

The present invention was created in order to solve the above problems, the forced circulation cooling type that can directly and quickly cool the temperature of the electrolyte in the electrolytic cell to give the optimal conditions to maximize the amount of brown gas generated in the electrolytic cell It is intended to provide a brown gas generator.

In addition, the present invention is to provide a forced circulation-cooled brown gas generator that can prevent the hunting (Hunting) by maintaining the level of the electrolytic cell evenly during the generation or cooling of the brown gas using a plurality of electrolytic cells.

Forced circulation-cooled brown gas generator according to an embodiment of the present invention for achieving the above object is an electrolytic cell comprising an electrolyte; An electrolyte circulation passage for circulating an electrolyte of the electrolytic cell to the outside of the electrolytic cell; A heat exchanger for cooling the electrolyte circulated along the electrolyte circulation path; A cooling device provided on one side of the heat exchanger to cool the heat exchanger by providing cooling water in the heat exchanger; And an electrolyte circulating pump formed in the electrolyte circulation path to forcibly circulate the electrolyte.

Forced circulation-cooled brown gas generator according to an embodiment of the present invention for achieving the above object is an electrolytic cell comprising an electrolyte; An electrolyte circulation passage for circulating an electrolyte of the electrolytic cell to the outside of the electrolytic cell; And a heat exchanger for cooling the electrolyte circulated along the electrolyte circulation path.
