Abstract

The invention provides a multi-stage cascade continuous solid adsorption carbon capture system and an operation method, carbon adsorption is performed on carbon-containing gas in a mass recovery unit through an enrichment part, a separation part and a purification part which are arranged in sequence, the enrichment part, the separation part and the purification part are heated through an industrial waste heat conduction part, and finally the heated gas is output to an application unit for subsequent application. When the enrichment part is heated by utilizing industrial waste heat, a re-adsorption reaction is formed by utilizing an adsorption material of the separation part, so that the regeneration of the adsorption material in the enrichment part is promoted, the regeneration energy consumption is reduced, and the economical efficiency is improved; the separation part is heated by utilizing industrial waste heat, and meanwhile, an adsorption material of the purification part is utilized to form a re-adsorption reaction, so that the regeneration of the adsorption material in the separation part is promoted, the regeneration energy consumption is reduced, and the economical efficiency is improved, and therefore, the economical efficiency of the adsorption carbon capture system disclosed by the embodiment of the invention is improved on the whole; the problem that an existing carbon adsorption scheme is poor in economical efficiency is solved.

Description

technical field [0001] The invention belongs to the technical field of carbon adsorption, and in particular relates to a multi-stage cascade continuous solid adsorption carbon capture system and an operation method. Background technique [0002] Carbon capture technology currently uses inorganic solution absorbents, organic amine solution absorbents, ionic liquid absorbents and solid adsorbents to achieve carbon dioxide enrichment. Among them, the adsorption method has lower operating costs than the solvent absorption method and oxygen-enriched combustion, and has higher technical maturity than the membrane separation method and chemical chain combustion. The adsorption method can also avoid the generation of amine solvents during use. of toxic and corrosive substances. Therefore, adsorption carbon capture technology has been highly valued by industry researchers and enterprises. [0003] Scholars at home and abroad have conducted research on adsorption carbon capture tech...
