FLUE GAS PURIFICATION SYSTEM CAPABLE OF COMPREHENSIVELY UTILIZING HEAT, AND PROCESS USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/035492
Kind Code:
A1
Abstract:
Provided are a flue gas purification system capable of comprehensively utilizing heat, and a process using same. The flue gas purification system capable of comprehensively utilizing heat comprises: a COAP system (1) comprising a desulfurization adsorption tower (12), a refrigerator (13) and a denitration adsorption tower (14) which are in sequential communication; a CO2 chemical absorption system (2) having a gas inlet in communication with a gas discharge port of the COAP system (1) and comprising a regeneration tower (22) provided with a reboiler (27) at the bottom thereof; and a steam heat utilization pipeline system (4) comprising a high-temperature steam conveying pipe (41) in communication with a regenerated-gas inlet of the desulfurization adsorption tower (12) and/or the denitration adsorption tower (14), a regenerated-gas discharge pipe (42) with one end thereof in communication with a regenerated-gas outlet of the desulfurization adsorption tower (12) and/or the denitration adsorption tower (14) and the other end thereof in communication with a gas inlet of the reboiler (27), and a steam recovery pipe (43) with one end thereof in communication with a gas outlet of the reboiler (27). Flue gas jointly treated by the COAP system (1) and the CO2 chemical absorption system (2) can achieve the goals of environmental protection, carbon peaking and carbon neutrality, and satisfies the requirement for emptying flue gas; and the cooling capacity of flue gas discharged from the COAP system (1) can be utilized step by step, thereby making full use of the cooling capacity.
