Abstract
Description
Technical Field
[0001] This utility model relates to the field of water purifier technology, specifically to an electrolytic hydrogen production device. Background Technology
[0002] Electrolytic hydrogen production equipment is a general term for a combination of devices using water as raw material, including a water electrolyzer, a hydrogen (oxygen) gas-liquid separator, a hydrogen (oxygen) cooler, and a hydrogen (oxygen) scrubber. Currently, home hydrogen-oxygen generators using proton exchange membrane (PEM) technology typically require users to periodically check the water level and manually add water. Even with pure water PEM hydrogen production machines, users need to periodically check the water level and add purified water as needed to ensure unobstructed water flow and normal machine operation. The operation procedures are relatively cumbersome and often consume a significant amount of manpower and time.
[0003] In view of this, there is an urgent need to provide a technical solution to the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an electrolytic hydrogen production device that addresses the shortcomings of existing technologies. This device can control a self-priming pump to draw water, thus solving the problem of traditional electrolytic hydrogen production devices requiring manual water addition, which wastes manpower and time.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] An electrolytic hydrogen production device includes a self-priming pump and an electrolysis device. The output end of the self-priming pump is connected to the electrolysis device. The electrolysis device includes an oxygen outlet, a hydrogen outlet, and a device body. The oxygen outlet is located on one side of the device body, and the hydrogen outlet is located on the other side of the device body opposite to the oxygen outlet.
[0007] A self-priming pump can automatically draw water for electrolysis into the electrolysis device for electrolysis, eliminating the need for manual refilling and saving manpower.
[0008] Furthermore, the electrolytic hydrogen production device includes a device body and an electrolytic water inlet located on one side of the device body. Electrolytic water flows into the device body from the electrolytic water inlet to carry out the electrolysis process.
[0009] Preferably, the electrolytic hydrogen production device includes an oxygen outlet, which is located on one side of the main body. Oxygen generated during electrolysis is discharged from the oxygen outlet and collected.
[0010] As an improvement to the hydrogen-rich water machine that produces ultrapure water according to this utility model, the electrolytic hydrogen production device also includes a hydrogen outlet. The hydrogen outlet is located on the other side of the main body relative to the oxygen outlet. The height difference between the oxygen outlet and the hydrogen outlet relative to the ground is 1 / 4 of the longitudinal direction when the column device is working. The hydrogen produced during the electrolysis process will be discharged from the hydrogen outlet and collected. Since the density of oxygen is greater than that of hydrogen, the design with a height difference between the two makes it easier to collect the gas and improves the collection rate.
[0011] Furthermore, the electrolyzed water inlet is connected to the self-priming pump, and the oxygen outlet is connected to the interior of the water supply device. The oxygen outlet is connected to the interior of the water supply device. Since the oxygen produced during water electrolysis in the electrolytic cell carries a relatively large number of small water droplets or water vapor from the electrolyzed water, the oxygen output from the oxygen outlet is first guided into the water supply device before being discharged to the outside. This allows for the recovery of the water carried away by the oxygen, saving water resources.
[0012] As an improvement of the hydrogen-rich water machine that produces ultrapure water according to this utility model, the height difference H between the hydrogen outlet and the oxygen outlet is 1 / 5 to 1 / 2 of the length of the electrolysis device.
[0013] Preferably, the height difference H between the hydrogen outlet and the oxygen outlet is 1 / 4 of the length of the electrolysis device. Since hydrogen is less dense than oxygen, setting a certain height difference between the hydrogen outlet and the oxygen outlet during the recovery of the two gases facilitates more precise separate collection. In this application, the height difference is set to 1 / 5-1 / 2, which results in better collection.
[0014] Furthermore, the self-priming pump is connected to the main control board. The main control board controls the self-priming pump to draw water for electrolysis, enabling automatic water addition for electrolysis without manual refilling.
[0015] Preferably, the oxygen outlet is connected to a water recovery device. During the electrolysis of water, some water is often carried out with the gas. Connecting a water recovery device to the oxygen outlet allows the carried-out water to be recycled, thus saving water resources used in electrolysis.
[0016] The beneficial effects of this invention are as follows: This electrolytic hydrogen production device can control a self-priming pump to draw water during use, eliminating the need for manual water addition and greatly saving manpower. The device has a simple structure, is easy to operate, and has good application prospects. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] The present invention will be further described in detail below with reference to the accompanying drawings, but this is not intended to limit the present invention.
[0027] Please refer to Figures 1 to 3 The electrolytic hydrogen production apparatus of the present invention will now be described.
[0028] This application provides an electrolytic hydrogen production device, including a self-priming pump 31 and an electrolysis unit 32, with the output end of the self-priming pump 31 connected to the electrolysis unit 32. This device eliminates the need for manual addition of electrolysis water during the electrolysis process; instead, the self-priming pump 31 automatically draws electrolysis water into the electrolysis unit 32 to complete the water electrolysis process, significantly saving manpower and time and improving production efficiency.
[0029] Furthermore, the electrolysis device 32 includes an oxygen outlet 322, a hydrogen outlet 323, and a device body 324. The oxygen outlet 322 is located on one side of the device body 324, and the hydrogen outlet 323 is located on the other side of the device body 324 opposite to the oxygen outlet 322.
[0030] Please refer to further information. Figure 1-2 In another embodiment of this application, the electrolytic hydrogen production apparatus further includes an apparatus body 324 and an electrolytic water inlet 321 disposed on one side of the apparatus body 324. During electrolysis, electrolytic water flows into the apparatus body from the electrolytic water inlet to complete the electrolytic hydrogen production process.
[0031] Please continue to refer to this. Figure 1-3 In some embodiments, the electrolyzed water inlet 321 is connected to the self-priming pump 31, and the oxygen outlet 322 is connected to the interior of the water supply device. Electrolyzed water is introduced into the electrolysis device 32 through the self-priming pump 31, and the oxygen produced by electrolysis can be recycled and reused through the water supply device, thus avoiding waste of water resources.
[0032] Please continue to refer to this. Figure 1-3 In some embodiments, after the electrolysis device 32 is installed, the hydrogen outlet 323 is positioned higher than the oxygen outlet 322 relative to the ground plane. Since the density of hydrogen is less than that of oxygen, setting the hydrogen outlet 323 higher than the oxygen outlet 322 allows for more accurate separation and collection of the two gases, improving the collection rate and reducing gas waste. Preferably, the height difference H between the hydrogen outlet 323 and the oxygen outlet 322 is 1 / 5 to 1 / 2. In this application, H is 1 / 4 of the length of the electrolysis device 32.
[0033] Please continue to refer to this. Figure 1 In another embodiment of this application, the self-priming pump 31 is connected to the main control board. The main control board sends a signal to the self-priming pump 31 to control the pump to operate and draw water for electrolysis, automatically completing the water addition in the electrolysis hydrogen production step without manual addition.
[0034] In some embodiments, the oxygen outlet 322 is connected to a water recovery device. The oxygen produced during water electrolysis in the electrolyzer carries a large number of small water droplets or water vapor from the electrolysis water. Connecting a water recovery device to the oxygen outlet 322 facilitates the collection of these small water droplets or water vapor for secondary use, reducing water waste and improving the utilization rate of water used in electrolysis.
[0035] Using this invention for hydrogen production by electrolysis:
[0036] The main control board controls the self-priming pump 31 to draw water for electrolysis, drawing the water into the electrolysis device 32 for electrolysis. The produced oxygen and hydrogen are discharged and collected from the oxygen outlet 322 and hydrogen outlet 323, respectively. The oxygen outlet 322 is connected to a water recovery device for water recovery and reuse.
[0037] It should be noted that the electrolytic hydrogen production device of this application can control a self-priming pump to draw water during use, eliminating the need for manual water addition, thus greatly saving manpower. It can also accurately separate and collect oxygen and hydrogen, improving the collection rate of both gases, reducing waste, and can recover water carried by the oxygen for secondary use. This device has a simple structure, significant effects, and good application prospects.

However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge.
