Title:
DEVICE SYSTEM AND METHOD HAVING SINTERING FLUE GAS CO CATALYTIC HEAT EXCHANGE AND MEDIUM-AND-LOW-TEMPERATURE SCR DENITRATION CONNECTED IN SERIES
Document Type and Number:
WIPO Patent Application WO/2023/231175
Kind Code:
A1
Abstract:
Disclosed in the present invention are a device system and method having sintering flue gas CO catalytic heat exchange and medium-and-low-temperature SCR denitration connected in series. In the device system, a CO catalytic heat storage and exchange device is arranged to completely replace an original heat exchanger arranged after a raw desulfurized flue gas pipe. The method comprises respectively carrying out first CO catalytic conversion and second CO catalytic conversion on sintering flue gas and denitrated flue gas by means of the CO catalytic heat storage and exchange device, thereby increasing CO conversion efficiency and reducing overall resistance of the system. In addition, the present invention takes both CO pollution control and carbon emission reduction into consideration and thus has good economic benefits and a good application prospect.
