Abstract

The invention relates to the technical field of flue gas purification, in particular to a coke oven flue gas desulfurization and dedusting system and method. The coke oven flue gas desulfurization anddedusting system comprises a heat exchanger, a desulfurization reaction unit, a dedusting unit and a fan; the heat exchanger comprises an original flue gas pipeline and a purified flue gas pipeline;the original flue gas pipeline, the desulfurization reaction unit and the dedusting unit are sequentially connected, a purified flue gas outlet of the dedusting unit is communicated to an inlet of thepurified flue gas pipeline, and an outlet of the purified flue gas pipeline is connected to the fan. The low temperature and intermittent characteristics of the coke oven flue gas discharge are combined, the temperature difference between purified flue gas and original flue gas is used, after the original flue gas is heated in the heat exchanger, the original flue gas is sent to the desulfurization reaction unit for desulfurization reaction, heat from the purified flue gas emitted is effectively utilized, thereby saving energy.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a coke oven flue gas desulfurization and dust removal system and method. Background technique [0002] The "Emission Standards for Pollutants in the Coking Chemical Industry" (GB16171-2012) (hereinafter referred to as "emission standards") clearly stipulates that from January 1, 2015, new and old coke ovens in general areas will be charged with coal and coke pushing flue gas Medium SO 2 The emission concentration limit is 50mg / Nm 3 , the special limit area is 30mg / Nm 3 , some areas even appear less than 15mg / Nm 3 ultra-low emission requirements. At present, in the coking field, only stable coke oven flue gas and advanced desulfurization and dust removal technology can meet the SO 2 and particulate matter emission standards, for coal loading, coke discharge, CDQ low-temperature intermittent dust removal flue gas SO 2 There is no mature and reliable process for ...
