Description

A carbon dioxide electrolytic humidifier water supply device

technical field

The invention relates to the technical field of water replenishment and filtration, in particular to a water replenishment device for a carbon dioxide electrolytic humidifier.

Background technique

Carbon dioxide electrolysis is the process of using green electricity to electrolyze carbon dioxide emitted by factories to produce high value-added chemicals such as formic acid and synthesis gas, so as to realize the transformation of waste into treasure and the consumption of surplus electricity. During the electrolysis process of carbon dioxide, by inputting carbon dioxide gas and water, chemicals such as formic acid, synthesis gas, and ethylene are produced through the electrolysis reactor. The relative humidity remains stable. During the working process of the humidifier, when the water level in the humidifier is lower than the set low water level, the replenishment pump will start to replenish water into the humidifier, and when the water level in the humidifier is replenished to the set high water level, stop replenishing water .
