Description

Technical Field

[0002] At present, common methods for purifying carbon dioxide include integrated condensation compressor method, purified carbon dioxide gas condenser method and gas organic activated carbon adsorption method.

When carbon dioxide passes through the activated carbon, it cannot fully contact all parts of the activated carbon, resulting in some parts of the activated carbon not being fully utilized, reducing the utilization efficiency of the activated carbon. Moreover, after a period of adsorption, when the adsorption capacity of the activated carbon decreases, the corresponding activated carbon cannot be quickly replaced, which is not conducive to the subsequent adsorption and purification of carbon dioxide, and needs to be improved.
