Description

Technical Field

[0001] The utility model relates to the technical field of water separation devices, in particular to a gas-water separation device for a hydrogen production system. Background Art

[0002] Hydrogen production by water electrolysis is one of the most widely used and mature hydrogen production methods, especially PEM water electrolysis, which has attracted widespread attention for its advantages such as high yield, high purity and good economic benefits. The process of using water as a raw material to produce hydrogen is actually the reverse process of hydrogen and oxygen burning to produce water. Therefore, as long as a certain form of energy is provided, water can be decomposed. However, in the hydrogen production process, since the hydrogen discharge end is in direct contact with the electrolyzed water, the hydrogen produced by the water electrolysis hydrogen production equipment contains water. In order to improve the purity of the produced hydrogen, it is necessary to remove the water in the hydrogen.

[0003] After searching, the existing Chinese patent announcement number is: CN220223599U, which provides a PEM water electrolysis hydrogen production test platform with a high-efficiency gas-water separation device. When the device is used, the hydrogen generated by the PEM water electrolysis hydrogen production test platform enters the double-switch drying component through the air intake pipe to dry the water content of the hydrogen after the first-level gas-water separation. The switching function of the double-switch drying component is utilized to realize uninterrupted drying of the water content of the hydrogen, thereby improving the drying efficiency of the hydrogen.

[0004] Although the above patent can improve the drying efficiency of hydrogen, the above device still has the following problems: after the device dries the hydrogen, the staff is required to heat and regenerate the activated alumina balls in the drying tank. However, due to the different positions of the activated alumina balls inside the tank, the activated alumina balls located in the center are not easy to be heated, which makes the regeneration speed of the activated alumina balls slower and makes it difficult for the activated alumina balls to be uniformly heated and regenerated. In view of the above situation, technical innovation is carried out on the basis of the existing device. Utility Model Content
