The present invention relates to a brown gas automatic supply device using an air-cooled electrolytic cell, the main body is composed of an electrolysis chamber with an electrolysis device and a water supply unit with a supplementary water automatic supply device.

The electrolysis chamber formed on the front of the main body is formed in a sealed type surrounded by a steel case, and then a certain number of rectangular air inlets are formed on the bottom of the electrolysis chamber as the number of electrolytic baths, and an air-cooled electrolytic cell is installed at a certain distance from the air inlet. Install side by side with electrolyte tank and power supply device on the top of the electrolytic cell, and install a large air blower on the upper side of the electrolysis chamber, so that the outside air flowing from the air inlet at the bottom of the electrolysis chamber is rapidly flowed between the protruding plates of the air-cooled electrolyzer. It is configured to cool efficiently while passing.

The water supply unit formed at the rear of the main body consists of a water purifier connected to the water pipe, a water tank for storing purified water, a pressurized pump for pressurizing the stored water and supplying it to the electrolyte tank automatically. The solenoid valve installed at the outlet of the pressurized tank operates according to the instructions of the installed level sensor so that the water is automatically supplied by the amount consumed in the electrolyzer.

Therefore, the present invention converts water into brown gas in an electrolysis device including an air-cooled electrolytic cell installed in the electrolysis chamber of the main body by receiving automatic water supply by the automatic replenishment water supply device installed in the water supply device chamber of the main body, thereby making it stable in the brown gas combustion device. It is designed to supply Brown gas, so that the air-cooled electrolytic cell does not exceed a certain temperature even during continuous operation for a long time.

Brown gas produced by the electrolysis of water exists in a mixed gas state in which hydrogen and oxygen are mixed in a chemical equivalence ratio of 2: 1 as water. Therefore, since it is completely burned by its own oxygen during combustion, it is not necessary to blow air into the combustion chamber.

The fact that oxygen is present in Brown gas has a tremendous benefit for us, but Brown gas must be burned by the combustion technology of Brown Gas. In other words, in order to use water as a fuel, the brown gas generator and the brown gas combustor must be connected by the WE system.

Water Energy System (WE Energy System) converts water (H2O) into brown gas (2H2 + O2) in the brown gas generator, and then heats the brown gas in the brown gas combustor by heat generation technology of brown gas. I say that

(21), a spacer (22) injection-molded with insulating material so that the stay holes (22a) are formed in four rooms, an O-ring (23) made of an alkali-resistant rubber material to prevent electrolyte leakage, and a finish It is composed of plates 24 and 24a, and the spacer 22 and the O-ring 23 are interlocked between the electrode plate and the electrode plate 21 to form an electrolyte filling chamber 29 so that a predetermined number of electrodes are formed. The plate 21 is arranged, and the electrolytic finish plates 24 and 24a are integrally formed at both ends and fastened and assembled by the stay bolts 27.

In particular, the configuration of the electrolytic cell 20 according to the present invention is to calculate the electrode plate area according to the gas production amount of the Brown gas generator by applying the formula that the electrode plate area = 14.25 × gas production amount and the number and unit of the appropriate electrode plate 21 The effective area of the electrode plate 21 is set to calculate the inner diameter of the O-ring 23 in which the actual electrolyte is filled, and accordingly, the size of the spacer 22 and the size of the electrode plate 21 are determined.

In the case of such a medium-large brown gas generator, unlike the cited patent 2, a large number of electrolyzers must be configured to increase the capacity, so the flow volume of the cloth flow fan has a limited electrolyzer size, which makes it difficult to increase the capacity, and the overall structure becomes complicated. Sufficient cooling effect can not be expected.

The present invention is to put the Brown gas automatic feeding device of the medium and large model into a high-tech process automated in a continuous process. For example, it aims to provide fuel supply for vacuum glass tube automatic cutting device using brown gas, which is used for cutting vacuum glass tube, which is essential for PDP / LCD panel line process such as Samsung / LG Electronics.
