Patent ID: 10918992

Abstract:
Provided are system and method thereof for desulfurization and dedusting of flue gas from a coke oven. The system for desulfurization and dedusting of flue gas from a coke oven includes a heat exchanger, a desulfurization reaction unit, a dedusting unit, and a blower; the heat exchanger includes a raw flue gas duct and a clean flue gas duct; the raw flue gas duct, the desulfurization reaction unit, and the dedusting unit are coupled in sequence, a clean flue gas outlet of the dedusting unit communicates with an inlet of the clean flue gas duct, and an outlet of the clean flue gas duct is coupled to the blower. The raw flue gas is heated in the heat exchanger by using temperature difference between clean flue gas and the raw flue gas, and then the raw flue gas is delivered into the desulfurization reaction unit for a desulfurization reaction.
