The pole tube 30 is a device installed in the electrolytic cell 10 to pass electricity transmitted through the electrode 20 into the electrolyte 50.

At this time, there is an electrolyte 50 of potassium hydroxide (KOH) or sodium hydroxide (NaOH) in the electrolytic cell 10. If electricity is supplied, Brown's Gas is generated between the electrodes in the electrolytic cell 10 through electrolysis. In order to make a large amount of Brown's Gas produced in each small electrolytic cell 10, a collecting tube 160 is installed on the top of the electrolytic cell 10, and the collected large amount of gas is transferred through the conduit.

3 is an example of the cathode tube fixture 40 for the forced circulation water-cooled cooling system Brown's Gas generator according to the embodiment. The cathode tube fixing tool 40 is installed in the upper and lower portions of the cathode tube 30 while being installed inside the electrolytic cell 10 to smoothly flow in and out of gas or water.

In the first embodiment, the cathode tube fixture 40 may be designed to increase the inflow and outflow area by having a sparder structure.

For example, by forming a plurality of wings from the center as shown in FIG. 3 can be designed to increase the outflow area of Brown's Gas or the electrolyte.

Meanwhile, the first embodiment may further include a water level sensor 120. The water level sensor 120 is connected to the collection pipe 160, the upper transport pipe 170, the lower transport pipe 80 of the top of the electrolytic cell (10) and detects the water level of the electrolyte 50, the water level signal is a controller (Controller) Is delivered to operate the water supply pump 60 to supply the insufficient water.

For example, when the Brown's Gas is produced in the electrolytic cell 10 according to the first embodiment, the water in the electrolytic cell 10 is reduced. At this time, the water level sensor 120 detects the water level in the electrolytic cell 10. After the transfer to the (not shown) to operate the water supply pump 60 to supply the cool cooling water supplied from the water tank 200 (see FIG. 1b) into the electrolytic cell 10, the water is supplied to the electrolytic cell 10 It is first supplied to the upper transfer pipe 70 is connected to and is supplied to each of the electrolytic cell 10 evenly through the upper transfer pipe (70).

In this case, the first embodiment employs a water level sensor 120 using a thermistor whose resistance varies with temperature, thereby detecting a resistance that changes with ambient temperature when the water level rises and falls, thereby stably and continuously increasing the water level of the electrolytic cell 10. Judging by Meanwhile, the first embodiment may use the water level ball as the water level sensor.

In addition, the first embodiment may further include a temperature sensor 130. The temperature sensor 130 is installed inside the electrolytic cell 10 and detects the temperature of the electrolyte 50. The temperature signal is transmitted to the controller to operate the electrolyte circulation pump 90 to circulate the electrolyte 50. It is supplied to the heat exchanger 100 to lower the temperature of the electrolyte 50.

The electrolyte circulating pump 90 is installed at the outlet of the lower transfer pipe 70 of the electrolytic cell 10 and is a pump for forcibly supplying the hot electrolyte 50 generated in the electrolysis process of the electrolytic cell 10 to the heat exchanger 100. .

For example, when producing Brown's Gas in the electrolytic cell 10, the temperature in the electrolytic cell 10 is increased. At this time, the temperature sensor 130 detects the water level in the electrolytic cell 10 and transmits it to the controller. When the circulation pump 90 is operated, the electrolyte solution 50 is collected in one place through the lower transfer pipe 80 arranged evenly with the electrolytic cell 10.

Direct connection with the heat exchanger 100 connected to the cooling tower 150 and the cooling water circulation pump 180 supplying the external cool cooling water by turning on SV1 and turning off SV2 and SV3 among the electrolyte filter solenoid valves 170 during a normal cooling operation.

For example, in order to remove the foreign substances generated in the electrolytic cell 10, the filter is determined by the controller after manual operation or a predetermined time operation by the driver. At this time, the SV1 of the electrolyte filter solenoid valve 170 is turned off and the SV2 and SV3 are turned on to bypass the pipeline so that the electrolyte solution 50 enters the heat exchanger 100 through the electrolyte filter 110. This reduces the load on the pump by minimizing the pressure in the pipeline while properly switching the circulation and filtering operations of the electrolyte, extending the life of the filter, and maintaining a stable and continuous operation.

In addition, the stable supply of cooling water is a very important factor in the workplace that requires continuous operation for 24 hours using Brown's Gas. Therefore, the cooling water cooled in the cooling tower 150 (see FIG. 1B) may be supplied with a BY-PASS structure pump by the plurality of cooling water circulation pumps 180 to supply continuous cooling water. Since there are a plurality of coolant circulation pumps 180, the fluid may not be greatly shaken even during the starting of the pump, thereby enabling continuous operation.

And only the liquid is supplied to the electrolyte circulation pump 90 to prevent the pump from being damaged by the gas.

That is, Brown's Gas generator is a structure that produces a mixed gas of hydrogen and oxygen by electrolyzing water due to its characteristics, and during normal operation, Brown's Gas rises to the upper part of the electrolytic cell 10 and a large amount of gas is driven when the electrolyte circulating pump 90 is driven. It is sent to the liquid containing the electrolyte circulation pump (90).
