Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic hydrogen production, in particular to a water sealing tank used in water electrolytic hydrogen production equipment. Background Art

[0002] Hydrogen production by water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed into an electrolytic cell filled with electrolyte, and water molecules undergo electrochemical reactions on the electrodes, decomposing into hydrogen and oxygen. The function of the water seal tank is to prevent the occurrence of flashback. If flashback occurs, the flame enters the water seal tank through the flare gas outlet, and the inlet pipe is below the water surface, thus preventing the flame from continuing to spread.

[0003] The water replenishment device of the existing hydrogen production equipment can only be operated through control valves and water pumps, which requires manual observation and control, increasing the workload and affecting the hydrogen production efficiency, and has high limitations in use.

[0009] In a possible implementation, a water-sealed tank body is fixedly mounted on the top of the base, and the bottoms of the oxygen tank and the hydrogen tank are fixedly connected to the base.

[0010] In a possible implementation, a first pipe and a second pipe are fixedly installed on the top of the oxygen tank and the top of the hydrogen pipe, respectively. The first pipe and the second pipe are both L-shaped and one end of each extends into the water seal tank body.

[0011] In a possible implementation, an electrolysis device is fixedly installed at the bottom of the inner wall of the water seal tank, an anode column is fixedly installed on one side of the top of the electrolysis device, and a cathode column is fixedly installed on the other side of the top of the electrolysis device, and the tops of the anode column and the cathode column extend into the first pipe and the second pipe respectively.

[0012] In one possible implementation, the automatic water replenishment mechanism includes a water replenishment tank, a water pipe, a suspension plate, a connecting rod, a first airbag, a support rod, a sealing ring, a sealing sleeve and a second airbag. The water replenishment tank is fixedly installed on the top of the water seal tank body, and a water pipe is fixedly installed on the bottom of the water replenishment tank and extends to the inside of the water seal tank body.

When the liquid level inside the water seal tank body reaches a certain height, the sealing ring is further contacted with the sealing sleeve to form a primary seal to prevent liquid from flowing out of the water pipe again. At the same time, the top of the support rod will further squeeze the first air bag, causing the first air bag to expand outward, blocking the water pipe, and performing a secondary seal to further prevent liquid from flowing out of the water pipe. When the liquid level inside the water seal tank body drops, the second air bag drives the support rod to drop synchronously, so that the water pipe and the water seal tank body are connected again for water replenishment.

[0023] The embodiments of the present application solve the problems in the prior art by providing a water seal tank for a water electrolysis hydrogen production device.

[0024] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0025] The specific structure of this embodiment is as follows: Figure 1-3 As shown, the water electrolysis hydrogen production equipment uses a water seal tank, including: a base 1, a water seal tank body 2 is arranged on the top of the base 1, an oxygen tank 3 is arranged on one side of the water seal tank body 2, a hydrogen tank 4 is arranged on the other side of the water seal tank body 2, a first pipeline 5 is arranged on the top of the hydrogen tank 4, a second pipeline 6 is arranged on the top of the oxygen pipe, an electrolysis device 7 is arranged on the bottom of the inner wall of the water seal tank body 2, an anode column 8 is arranged on one side of the top of the electrolysis device 7, a cathode column 9 is arranged on the other side of the top of the electrolysis device 7, and an automatic water replenishment mechanism 10 is arranged on the top of the electrolysis device 7.

[0026] In some examples, a water seal tank body 2 is fixedly installed on the top of the base 1, the bottoms of the oxygen tank 3 and the hydrogen tank 4 are fixedly connected to the base 1, the first pipe 5 and the second pipe 6 are fixedly installed on the top of the oxygen tank 3 and the top of the hydrogen pipe, respectively, the first pipe 5 and the second pipe 6 are both L-shaped and one end extends into the water seal tank body 2, an electrolysis device 7 is fixedly installed on the bottom of the inner wall of the water seal tank body 2, an anode column 8 is fixedly installed on one side of the top of the electrolysis device 7, and a cathode column 9 is fixedly installed on the other side of the top of the electrolysis device 7, the tops of the anode column 8 and the cathode column 9 extend into the first pipe 5 and the second pipe 6 respectively, the electrolysis device 7 is powered on and started, so that the anode column 8 and the cathode column 9 react with the liquid inside the water seal tank body 2, thereby electrolyzing oxygen and hydrogen, and transporting them to the oxygen tank 3 and the hydrogen tank 4 through the first pipe 5 and the second pipe 6 respectively.

[0027] In some examples, the automatic water replenishment mechanism 10 includes a water replenishment tank 101, a water pipe 102, a suspension plate 103, a connecting rod 104, a first airbag 105, a support rod 106, a sealing ring 107, a sealing sleeve 108 and a second airbag 109. The water replenishment tank 101 is fixedly installed on the top of the water seal tank body 2, the water pipe 102 is fixedly installed at the bottom of the water replenishment tank 101 and extends to the inside of the water seal tank body 2, the suspension plate 103 is located inside the water pipe 102, the connecting rod 104 is fixedly installed between the suspension plate 103 and the inner wall of the water pipe 102, the first airbag 105 is fixedly installed at the bottom of the suspension plate 103, the support rod 106 is located directly below the first airbag 105, the surface of the support rod 106 is fixedly sleeved with a sealing ring 107, and the sealing sleeve 108 is fixedly sleeved with a sealing ring 107. 8 is fixedly installed on the inner wall of the water pipe 102 and is located just above the sealing ring 107. A second air bag 109 is fixedly installed at the bottom of the support rod 106. The water replenishment tank 101 transports liquid into the water seal tank body 2 through the water pipe 102, so that the liquid level inside the water seal tank body 2 increases, and at the same time pushes the second air bag 109 and the support rod 106 to float. When the liquid level inside the water seal tank body 2 reaches a certain height, the sealing ring 107 is further contacted with the sealing sleeve 108 to form a primary seal to prevent the liquid from flowing out of the water pipe 102 again. At the same time, the top of the support rod 106 will further squeeze the first air bag 105, so that the first air bag 105 expands outward, blocks the water pipe 102, and performs a secondary seal to further prevent the water pipe 102 from flowing out of the liquid.

[0028] In a specific application scenario, the electrolysis device 7 is powered on and started, so that the anode column 8 and the cathode column 9 react with the liquid inside the water seal tank 2, thereby electrolyzing oxygen and hydrogen, and transporting them to the oxygen tank 3 and the hydrogen tank 4 through the first pipe 5 and the second pipe 6 respectively. When the liquid level inside the water seal tank 2 drops, the second airbag 109 drives the support rod 106 to drop synchronously, so that the water pipe 102 is connected to the water seal tank 2 for water replenishment. When the liquid level inside the water seal tank 2 reaches a certain height, the second airbag 109 and the support rod 106 are pushed to float, and the sealing ring 107 is further contacted with the sealing sleeve 108 to form a primary seal. At the same time, the top of the support rod 106 further squeezes the first airbag 105, so that the first airbag 105 expands outward, blocks the water pipe 102, and performs a secondary seal to prevent liquid from flowing out of the water pipe 102.

[0029] By adopting the above technical solution: the water electrolysis hydrogen production equipment can automatically replenish water using a water seal tank without manual intervention.

[0030] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
