Description

Technical Field

[0001] This utility model relates to the field of water-nickel-based catalyst reaction technology, specifically to a water-electrolysis nickel-based catalyst reaction tank. Background Technology

[0002] In water electrolysis for hydrogen production, nickel-based catalysts exhibit activity close to that of precious metals but are inexpensive, making them suitable for large-scale water electrolysis. They are also corrosion-resistant and carbon-resistant in alkaline environments, have a long lifespan, and are easy to recycle. Furthermore, their structure is tunable (e.g., nano-sizing, doping), leading to their widespread use. However, to ensure uniform heating in localized areas, nickel-based catalyst reactors for water electrolysis utilize an electrolyte circulation system, while filtration removes impurities. This process requires shutting down the equipment, is time-consuming and labor-intensive, and impurities stuck in the filtration structure are difficult to remove completely, presenting certain drawbacks. Therefore, we propose a nickel-based catalyst reactor for water electrolysis. Utility Model Content

[0004] Therefore, the technical solution adopted by this utility model is as follows: an electrolytic water nickel-based catalyst reaction tank, including a tank body, a circulation pipe, a circulation pump, a filter pipe, a filter assembly, and a spray pipe. The circulation pipe is fixedly arranged on the right side of the tank body, and a first electric valve and a second electric valve are sequentially arranged on the circulation pipe. The circulation pump is fixedly arranged on the circulation pipe. The filter pipe is welded to the circulation pipe, and a drain pipe is fixedly arranged at the bottom of the filter pipe, and a valve is fixedly arranged on the drain pipe. The filter assembly includes a fixed plate fixedly arranged at the top of the filter pipe, a rotary motor fixedly arranged at the top of the fixed plate, a rotating shaft fixedly arranged at the output end of the rotary motor, and a filter screen fixedly arranged at the bottom of the rotating shaft. The spray pipe is fixedly arranged on the filter pipe, and several nozzles are fixedly arranged at the bottom of the spray pipe.

[0005] Preferably, an electrode plate and a diaphragm are fixedly arranged on the inner side of the tank, and inlet pipes are provided at both the front and rear ends of the tank.

[0006] Preferably, the top end of the filter tube has an insertion hole for installing the filter assembly.

[0007] Preferably, the fixing plate has a plurality of mounting holes, and the fixing plate is fixedly connected to the top end of the filter tube by bolts.

[0009] Preferably, it also includes a heat exchanger, which is fixedly installed outside the circulation pipe, and an inlet pipe and a drain pipe are respectively provided on both sides of the heat exchanger.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The first electric valve of this utility model can be controlled to close, thereby allowing the electrolyte in the filter tube to be extracted by the circulating pump. Then, the second electric valve can be controlled to close, and the spray pipe can be connected to a tap water pipe to deliver tap water to the nozzle for spraying. The sprayed water can wash the filter screen, and the rotating motor can drive the filter screen to rotate through the rotating shaft, thus washing the filter screen without dead angles to thoroughly clean impurities. After cleaning, the valve can be rotated to open, and the impurities can be discharged through the drain pipe. This process does not require stopping the equipment and is highly efficient. Then, the liquid inlet pipe can be connected to room temperature water, and the water temperature can be raised through heat transfer to recover waste heat and reduce energy consumption.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a reaction vessel for electrolytic water nickel-based catalyst.

[0026] Example 1:

[0027] Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a water electrolysis nickel-based catalyst reaction tank, including a tank body 100, a circulation pipe 200, a circulation pump 300, a filter pipe 400, a filter assembly 500, and a spray pipe 600.

[0028] Specifically, an electrode plate 101 and a diaphragm 102 are fixedly installed on the inner side of the tank 100. Inlet pipes 103 are provided at both the front and rear ends of the tank 100. During use, the electrode plate 101 can conduct current, distribute electrolyte, and expel air bubbles, while the diaphragm 102 can prevent hydrogen and oxygen from mixing. Pure water can enter through the inlet pipe 103 to facilitate the electrolysis reaction.

[0029] Specifically, the circulation pipe 200 is fixedly installed on the right side of the tank 100. A first electric valve 201 and a second electric valve 202 are sequentially installed on the circulation pipe 200. In use, the circulation pipe 200 can be closed by controlling the first electric valve 201 and the second electric valve 202 in order to clean the impurities in the filter pipe 400.

[0030] Specifically, the circulation pump 300 is fixedly installed on the circulation pipe 200. During use, the circulation pump 300 can pump the electrolyte in the tank 100 into the circulation pipe 200, and then the electrolyte returns to the tank 100, which can accelerate the liquid flow speed so as to achieve uniform heating.

[0031] Specifically, the filter tube 400 is welded to the circulation pipe 200. A drain pipe 401 is fixed to the bottom of the filter tube 400, and a valve 402 is fixed to the drain pipe 401. The top of the filter tube 400 is provided with an insertion hole 403 for installing the filter assembly 500. In use, the drain pipe 401 can be opened by rotating the valve 402 to discharge impurities, and the filter assembly 500 can be inserted through the insertion hole 403 to install the filter assembly 500.

[0032] Specifically, the filter assembly 500 includes a fixing plate 501 fixedly mounted on the top of the filter tube 400, a rotary motor 502 fixedly mounted on the top of the fixing plate 501, a rotating shaft 503 fixedly mounted on the output end of the rotary motor 502, and a filter screen 504 fixedly mounted on the bottom of the rotating shaft 503. The fixing plate 501 has several mounting holes 5011, and the fixing plate 501 is fixedly connected to the top of the filter tube 400 by bolts. In use, the filter assembly 500 is fixed by bolts to facilitate disassembly and maintenance of the filter assembly 500. The rotary motor 502 can drive the rotating shaft 503 and the filter screen 504 to rotate, so that the filter screen 504 can use centrifugal force to throw off impurities, thereby thoroughly cleaning the impurities.

[0033] Specifically, the spray pipe 600 is fixedly installed on the filter pipe 400, and several nozzles 601 are fixedly installed at the bottom of the spray pipe 600. The spray pipe 600 is fixedly connected to the tap water pipe. When in use, tap water can be delivered through the spray pipe 600 to the nozzles 601 and sprayed out. The sprayed tap water can rinse the filter screen 504 to thoroughly clean impurities.

[0034] Example 2:

[0035] Reference Figure 1 and Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a heat exchanger 700. The heat exchanger 700 is fixedly installed outside the circulation pipe 200. An inlet pipe 701 and a drain pipe 702 are respectively provided on both sides of the heat exchanger 700. In use, clean water can be transported into the circulation pipe 200 through the inlet pipe 701. After being transported, the temperature of the water can be increased by utilizing the heat transfer property. Then, it is discharged through the drain pipe 702, which can recover waste heat and reduce the temperature of the electrolyte.

[0036] The working principle and usage process of this utility model are as follows: First, the first electric valve 201 is closed. Then, the circulating pump 300 is controlled to extract the electrolyte from the filter tube 400. After extraction, the second electric valve 202 is closed. Next, the spray pipe 600 is connected to a tap water pipe. After connection, tap water is delivered through the spray pipe 600 to the nozzle 601 and sprayed out. The sprayed water washes the filter screen 504. Simultaneously, the rotary motor 502 is controlled to operate. The rotating motor 502 drives the filter screen 504 to rotate through the rotating shaft 503, achieving thorough washing. After washing, the valve 402 can be rotated to open, allowing impurities to be discharged through the drain pipe 401, thus cleaning the impurities. During heat exchange, room temperature water is introduced into the inlet pipe 701, then enters the heat exchanger 700, where it is heated. The heated water is then discharged through the drain pipe 702, thus lowering the electrolyte temperature.
