Abstract
The present disclosure provides a carbon capture system applicable to solid amine materials with various particle sizes, including: an adsorption assembly, a separation unit, a first desorption unit, a fine powder recovery assembly, a second desorption unit and a fine powder silo assembly; wherein the adsorption assembly adsorbs carbon dioxide in external flue gas/air by solid amine with mixed particle sizes; the separation unit separates the solid amine with the mixed particle sizes; the first desorption unit desorbs the separated solid amine by bubbling; the fine powder recovery assembly screens solid amine escaping from the gas outlet end of the first desorption unit; and the second desorption unit inputs the recovered solid amine particles into the second desorption unit for vacuum desorption. The present disclosure can achieve particle size screening and match different desorption processes based on the solid amine particle size.
