Description

Technical Field

[0001] The utility model relates to the technical field of catalyst filtering, in particular to a filtering device for a catalyst for producing hydrogen by electrolysis of water. Background Art

[0002] Hydrogen is a clean secondary energy source with a very light weight and high energy density, so it is easy to store and transport. It does not produce any pollutants or greenhouse gases during use. In industry, hydrogen is currently mainly obtained through methods such as methane or other hydrocarbon reforming, which still consumes fossil energy and produces a large amount of carbon dioxide and toxic gases containing sulfur and nitrogen oxides. Hydrogen is prepared by electrolysis, which has the advantages of high product purity, high efficiency, and small equipment footprint. With the continuous reduction of power generation costs such as wind power and photovoltaic power generation, water electrolysis to produce hydrogen is expected to gradually replace traditional industrial methods such as methane steam reforming and coal gasification to prepare hydrogen. Platinum carbon, iridium oxide, iridium ruthenium alloy and other catalysts are needed in the process of water electrolysis to produce hydrogen.

[0003] For example, a Chinese utility model provides "a screening device for catalyst production", announcement number: CN220406287U, which includes a box body with an opening at the lower end, a lifting assembly is provided at the lower end of the box body, a collecting box is placed on the lifting assembly, the upper end of the collecting box is plugged into the lower port of the box body, and two groups of screening assemblies are provided in the vertical direction inside the box body. The utility model provides guide grooves and conical expansions to facilitate pushing the collecting box onto the pallet and positioning it, and facilitates the upper end of the collecting box to be plugged into the lower end of the box body after the pallet moves upward.

However, since it is impossible to crush the larger catalysts and agglomerates during the operation, personnel often need to take out the catalysts after filtering and screening and then crush them.
