Description

Technical Field

[0001] The invention relates to the technical field of automatic circulation of alkali solution, in particular to an automatic circulation device for alkali solution. Background Art

[0002] Hydrogen production by water electrolysis is one of the main technologies for achieving clean electricity consumption and green hydrogen production. Hydrogen production by alkaline water electrolysis has attracted widespread attention and application due to its high technical maturity and significant price advantage. During the electrolysis process of this technology, the alkali stored in the alkali tank is injected into the electrolyzer through the alkali pump, and a redox reaction occurs in the electrolyzer to generate hydrogen and oxygen, which are then discharged through the hydrogen gas path and oxygen gas path at both ends of the electrolyzer.

[0003] They enter the hydrogen separator and oxygen separator for gas separation. The hydrogen separated by the hydrogen separator enters the hydrogen purification device, and the alkali liquid flows back to the alkali liquid tank for the next cycle. The oxygen separated by the oxygen separator enters the oxygen purification device, and the alkali liquid flows back to the alkali liquid tank for the next cycle.

[0004] At present, the hydrogen-alkali liquid separator and the oxygen-alkali liquid separator ensure the dynamic balance of the alkali liquid level through a balance pipe. The alkali liquid flows into the alkali liquid cooler through the pipe for cooling, and then is filtered through the alkali liquid filter. Finally, it is pumped back to the electrolytic cell by the circulation pump to participate in electrolysis, forming a closed-loop system to ensure continuous operation.

[0005] The existing automatic alkali liquid circulation device has the following shortcomings in use: usually, when the alkali liquid return pipe circulates the alkali liquid, it is necessary to connect the pipes with multiple sections and types of elbows. When the alkali liquid converges at the elbow, it is easy to cause the liquid flow rate to be too fast, resulting in vortices inside the pipe, thereby forming sediments. As time goes by, these sediments will continue to accumulate, resulting in a decrease in the pipeline flow rate. The sediments are difficult to clean and the inner wall of the pipe will gradually wear out, forming some protrusions and sunken parts. Once leaking, it will cause considerable losses, which will invisibly increase the cost and reduce the alkali liquid circulation effect of the overall device.

[0006] Therefore, those skilled in the art provide an automatic alkali solution circulation device to solve the problems raised in the above background technology. Summary of the invention

Under the obstruction of the claw frame, the flow volume can be controlled, thereby reducing the flow rate of the alkali solution after passing through, which is conducive to adjusting the flow rate of the alkali solution fluid, avoiding excessively high or low flow rates, reducing the generation of eddy currents, and preventing impurity deposition;

After the micro servo motor is turned on, the output shaft drives the take-up and release roller to rotate in the opposite direction, thereby releasing the reinforcing wire wound outside the take-up and release roller, and with the impact of the alkali liquid, the cleaning ball is driven to swing on the inner wall of the diversion pipe and contact with the inner wall of the pipe, and flows into the diversion inclined pipe with the alkali liquid until it stops at the end of the diversion inclined pipe. At this time, the impurities scraped by the diversion inclined pipe and the diversion pipe are taken away and then filtered, and the adsorption cleaning liquid on the surface of the cleaning ball is released under the flushing of the alkali liquid. After several repetitions, the micro servo motor and the micro push rod are reset, and different adsorption treatment liquids can be added through the filling pipe, which is beneficial to cleaning the adsorbed impurities inside the alkali liquid circulation pipe, preventing sediment accumulation, and ensuring the automatic circulation quality of alkali liquid reflux.

When the alkali liquid converges at the elbow, it is easy to cause the liquid flow rate to be too fast, resulting in vortexes inside the pipe, thereby forming sediments. As time goes by, these sediments will continue to accumulate, resulting in a decrease in the pipe flow rate. The sediments are difficult to clean, and the inner wall of the pipe will gradually wear out, forming some protrusions and sunken parts.

When the alkali liquid enters the fourth delivery pipe 32 at a normal flow rate, the alkali liquid passes through the path between the first guide plate 38, the second guide plate 39 and the third guide plate 42 to control the size and position of the vortex, and is smoothly delivered to the third delivery pipe 15 through the fourth delivery pipe 32. The heat generated by the decomposition of H2O is taken out by the cooling water through the alkali liquid cooler 14. The impurities filtered out by the liquid filter 11 are processed and then pumped into the electrolytic cell 7. Then, when the flow rate is too fast, the alkali solution flows and impacts the claw frame 41, so that the entire guide plate 37 and the second guide plate 39 are driven to move in the fourth conveying pipe 32. Driven by the second guide plate 39, the two traction rods 43 respectively drive the first guide plate 38 and the third guide plate 42 to move. Further, when the first guide plate 38 and the third guide plate 42 are active, they move in the guide groove 40, thereby changing the position and angle, so that the channel from the first guide plate 38 to the third guide plate 42 is closed, so that the alkali solution can only pass through The liquid flows through the back of the first guide plate 38 and flows through both sides of the guide plate 37. The flow rate can be controlled under the obstruction of the claw frame 41, thereby reducing the flow rate of the alkali solution after passing through. After the alkali solution circulates for a predetermined time, the switch of the micro push rod 21 is first turned on from the external controller. The extended end of the micro push rod 21 drives the linkage piece 28 to move downward in the operating frame 27. Driven by the linkage piece 28, the cylinder 24 descends and enters the inner side of the guide pipe 18. At this time, the switch of the micro servo motor 20 is turned on from the external controller. After the micro servo motor 20 is running, the output shaft drives the retracting roller 2 2 rotates in the opposite direction, thereby releasing the reinforcing wire 23 wound outside the retracting roller 22, and with the impact of the alkali solution, the cleaning ball 30 is driven to swing on the inner wall of the diversion pipe 18 and contact the inner wall of the pipe, and flows into the diversion inclined pipe 17 with the alkali solution until it stops at the end of the diversion inclined pipe 17. At this time, the impurities scraped by the diversion inclined pipe 17 and the diversion pipe 18 are taken away and then filtered, and the adsorption cleaning liquid on the surface of the cleaning ball 30 is released under the flushing of the alkali solution.
