Abstract
A device and a method for capturing carbon dioxide and producing an organic weak acid salt. The device uses ammonia, chloroacetic acid, and hexamethylenetetramine as raw materials to prepare a non-amine carbon dioxide absorbent in the spray evaporation tower, then the non-amine carbon dioxide absorbent is transmitted to an atomizing carbon dioxide absorption tower, and the non-amine carbon dioxide absorbent is dispersed in the atomizing carbon dioxide absorption tower through second atomizing nozzles; a flue gas enters the atomizing carbon dioxide absorption tower, and the flue gas is mixed with the non-amine carbon dioxide absorbent to capture carbon dioxide; the non-amine carbon dioxide absorbent containing the carbon dioxide is transmitted to a carbon dioxide desorption chamber to obtain desorbed carbon dioxide and desorbed non-amine carbon dioxide absorbent; the desorbed non-amine carbon dioxide absorbent is transmitted to the absorbent storage tank for cooling crystallization to obtain the organic weak acid salt.
