The electrolyte storage tank consists of a storage tank shell, a storage tank low-level sensor, and a storage tank drain valve, and is connected to the electrolytic tank via the electrolyte replenishment valve. The control device controls the electrolytic hydrogen production device and performs cleaning and maintenance according to the program set by the electrolytic hydrogen production device. The structure is simple, energy consumption is reduced, and safety is improved. In actual operation, it is easy to parallelize the electrolytic cells as units to achieve economies of scale.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process.
[0020] Conventional hydrogen production equipment cannot dry out moist hydrogen during use, nor does it remove the small amount of oxygen in the hydrogen. This affects the purity of the hydrogen, thus reducing the quality of hydrogen production. If subsequent purification operations are required, the workload increases, causing inconvenience to users.
[0021] In view of this, the utility model provides an electrolytic hydrogen production device, which can dry the moist hydrogen and oxygen through the cooperation of the box and the treatment and discharge device, and can also remove a small amount of oxygen in the hydrogen, thereby ensuring the purity of the prepared hydrogen, and does not require the staff to perform subsequent purification work, thus bringing convenience to the staff's use and reducing the staff's work intensity.
[0022] Example 1: By Figure 1 、 2 , 3 and 4 show that an electrolytic hydrogen production device includes a box body 1, a partition 6 is installed inside the box body 1, a sewage pipe 7 is provided at the lower side of one side of the box body 1, and a treatment and discharge device 2 is provided on both sides of the box body 1. The treatment and discharge device 2 includes: an outlet pipe 21, two of which are respectively installed on both sides of the top of the box body 1; a guide box 22, two of which are respectively installed on both sides of the outer wall of the box body 1; a first orifice plate 23, two of which are respectively installed on both sides of the top of the box body 1 and are respectively fixed to the inner walls of the two guide boxes 22; a connecting pipe 24, two of which are respectively installed at the lower side of one side of the two guide boxes 22; a second orifice plate 25, two of which are respectively installed on both sides of the outer wall of the box body 1 and are respectively fixed to the inner walls of the two guide boxes 22; a plurality of sodium plates 26 are provided, all of which are installed on the inner wall of the guide box 22 away from the sewage pipe 7; wherein the upper part of the interior of the two guide boxes 22 is filled with a desiccant, and the sodium plate 26 can adsorb oxygen in the hydrogen;
[0023] In the specific implementation process, it is worth noting that the remaining electrolyte after electrolysis can be discharged from the interior of the box 1 through the drain pipe 7, and the hydrogen and oxygen generated during electrolysis can be discharged from the interior of the box 1 through the two outlet pipes 21. The material of the desiccant filled in the guide box 22 is not limited, as long as it meets the use requirements. The sodium plate 26 can adsorb the oxygen in the hydrogen, and the staff regularly replaces the sodium plate 26 according to actual use.
[0024] Furthermore, a one-way valve 241 is installed inside the two connecting pipes 24;
[0025] In the specific implementation process, it is worth noting that the design of the one-way valve 241 can prevent external air from entering the interior of the guide box 22;
[0026] Specifically, when using the electrolytic hydrogen production device, when oxygen and hydrogen enter the interior of the two guide boxes 22 respectively, they can be adsorbed and dried in advance by the desiccant, and then the oxygen is discharged from the connecting pipe 24 on the side close to the sewage pipe 7, and the hydrogen first passes through the sodium plate 26. At this time, the sodium plate 26 can adsorb the oxygen and then discharge it from the connecting pipe 24 on the side away from the sewage pipe 7.

The power connection device 51 is connected to an external power supply device, and hydrogen is produced by electrolysis through the cathode 52 and the anode 53.

[0031] In the specific implementation process, it is worth noting that there is no restriction on the models of the liquid level sensor 31 and the controller 32, as long as they meet the use requirements. In addition, the present invention should be equipped with an alarm used in conjunction with the detection device 3, so that when the liquid level is insufficient, the alarm can provide a warning. There is no restriction on the specifications and types of the alarm, as long as they meet the use requirements.
[0032] Specifically, based on the above-mentioned embodiment 1 and embodiment 2, when the liquid level inside the box body 1 is insufficient, the liquid level sensor 31 can transmit the detection signal to the controller 32, and the controller 32 can control the external alarm device to issue an alarm reminder.

[0034] In the specific implementation process, it is worth noting that the electrolyte inside the liquid tank 41 can enter the interior of the box body 1 through the first conduit 42 and the second conduit 43;
[0035] Specifically, based on the above-mentioned embodiments 1, 2 and 3, when rehydration is performed, the staff opens the control valve of the first conduit 42, and the electrolyte inside the liquid tank 41 can enter the interior of the box body 1 through the first conduit 42 and the second conduit 43.
