Description

Technical Field

[0001] The invention relates to the technical field of hydrogen storage equipment, in particular to a hydrogen storage device for producing hydrogen from methanol with a self-cleaning filter structure. Background Art

[0002] Methanol hydrogen production technology uses advanced methanol steam reforming-pressure swing adsorption technology to produce pure hydrogen and CO2-rich mixed gas. After further post-processing, hydrogen and carbon dioxide can be obtained at the same time. Methanol hydrogen production can reduce energy consumption and costs in chemical production, replacing the "electrolysis of water to produce hydrogen" process known as the "electricity tiger"; When storing the produced hydrogen, it is necessary to remove impurities in the hydrogen to avoid affecting the corresponding equipment during subsequent applications. For example, the prior art CN216223438U proposes a hydrogen filter element, which can be loaded onto the inlet end of the hydrogen storage tank to filter the stored hydrogen and ensure the cleanliness of the stored hydrogen.

[0003] The above-mentioned filter element is applied to the hydrogen storage tank. Although it can filter the hydrogen, as the use progresses, more and more impurities are collected in the filter element, which will affect the ventilation volume of the filter element and cause the air intake resistance to increase.
