Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production and drying, in particular to a hydrogen generator device. Background Art

[0002] The hydrogen generator produces oxygen at the anode of the electrolytic cell and hydrogen at the cathode through the electrolysis of water, and the generated hydrogen is output for user use; the high-purity hydrogen generator is an auxiliary device for the gas chromatograph, supplying high-purity hydrogen to the gas chromatograph. The high-purity hydrogen generator mainly consists of an electrolytic cell unit, an electrical control unit, a gas circuit unit including a gas-liquid separation device, a pressure indicator and a gas purifier.

[0003] The electrolytic separation cell is a barrel-type structure that uses advanced membrane permeation technology and liquid level difference circulation gravity flow. The working principle is that under the action of the electric field, the anode of the electrolytic cell produces oxygen and the cathode produces hydrogen. The oxygen is released into the atmosphere through the liquid path, while the hydrogen enters the purification system and is output. When the hydrogen pressure rises to the set value, the pressure control system will automatically adjust to a stable state according to the hydrogen usage of the chromatograph. At this time, the amount of hydrogen generated and the output are equal. Since the electrolytic separation cell is connected to the gas chromatograph, there are strict requirements on the water vapor content. The electrolytic separation cell in the prior art is provided with a silica gel desiccant, which is placed in the drying tube of the electrolytic separation cell. When the silica gel desiccant fails, it needs to be replaced immediately. However, in actual operation, it is inconvenient to replace the silica gel desiccant due to the influence of the operating space. Therefore, a solution is proposed in the prior art.

[0004] For example, Chinese patent publication number CN205420561U discloses a drying device for a hydrogen generator electrolytic separation cell, comprising a barrel-shaped electrolytic separation cell, a feed port on the upper end face of the barrel-shaped electrolytic separation cell, a shell connected to the feed port, a paper bag provided in the shell, a desiccant provided in the paper bag, a shell cover threadedly connected to the upper end of the shell, an observation hole provided on the upper surface of the shell cover, a glass seal provided in the observation hole, a through hole provided on the bottom surface of the shell, and the through hole connected to the feed port of the electrolytic separation cell. A groove is provided on the bottom surface of the shell, and the groove is sealed with the feed port of the electrolytic separation cell. The cross section of the shell is circular. This device can effectively dry the electrolytic separation cell chamber, ensure the normal operation of the gas chromatograph, and is extremely convenient for placing or replacing the desiccant.

[0005] There are still deficiencies in the above application. In the above application, a desiccant is set in a paper bag, and the desiccant is stacked inside the shell. Moisture is discharged from the through hole and contacts the bottom of the desiccant. The bottom of the desiccant absorbs more moisture, while the top of the desiccant absorbs less moisture. The moisture absorption uniformity is poor, which affects the overall moisture absorption and drying effect, reduces the full utilization of the desiccant, and increases the frequency of desiccant replacement.
