Problems solved by technology
[0003] In the alkaline water electrolysis industry, oxygen is usually not used, and it is emptied into the atmosphere, and hydrogen is used. However, the hydrogen after the above-mentioned simple treatment has a high dew point due to its high water content, which cannot meet the requirements of subsequent production.

The invention relates to the technical field of drying, in particular to a drying device applied to drying of hydrogen prepared through water electrolysis. The drying device comprises a first water catcher, a first adsorber, a second adsorber and an output pipeline. According to the drying device, the hydrogen containing water prepared through water electrolysis is input into the first water catcher by a water electrolysis hydrogen pipeline, then is divided to flow into the first adsorber and the second adsorber at the same time and then is output from an output pipeline; and the first water catcher is mainly used for carrying out primary drying, a part of water is intercepted, the first adsorber and the second adsorber are mainly used for carrying out secondary drying on the hydrogen prepared through water electrolysis, and the hydrogen is then output from the output pipeline after being dried twice. The drying device has the advantages that the hydrogen prepared through water electrolysis is effectively dried, so that the hydrogen prepared through water electrolysis does not contain the water after being dried, and the production requirements can be met; and the operation is convenient, the drying speed is high, and the water removal efficiency is high.
Description
technical field [0001] The invention relates to the field of drying technology, in particular to a drying device applied to water electrolysis hydrogen drying. Background technique [0002] The general technological process of hydrogen production by water electrolysis is: use 25-30% potassium hydroxide or sodium hydroxide aqueous solution as the electrolyte, and the electrolyzer usually works at 80-90°C. Water is electrolyzed into H2 and O2 in the electrolyzer, and enters the hydrogen, oxygen and liquid separators in the gas-liquid post-processing device together with the unelectrolyzed lye, and the separated gas is washed and cooled by gas. [0003] In the alkaline water electrolysis industry, oxygen is usually not used, and it is emptied into the atmosphere, and hydrogen is used. However, the hydrogen after the above-mentioned simple treatment has a high dew point due to its high water content, which cannot meet the requirements of subsequent production. Contents of the ...
