Abstract

The invention relates to the technical field of flue gas purification and discloses boiler flue gas integrated desulfurization treatment equipment which comprises a desulfurization treatment tank, a flow guide assembly, a filtering assembly, a spraying assembly, a driving linkage assembly, a cleaning dredging assembly and a guide recovery assembly. After the flue gas enters the desulfurization treatment tank, the flue gas uniformly flows to the filter assembly under the action of the flow guide assembly, and the spray assembly sprays the absorption liquid to the filter assembly, so that the flue gas is fully contacted with the absorption liquid to complete desulfurization. The filter plate in the filter assembly can relatively reciprocate, and the filter plate surface and the filter holes are cleaned and dredged by the cleaning and dredging assembly under the drive of the driving linkage assembly, and meanwhile, sediment is softened by the injection of the softener, so that the blockage is reduced. The desulfurization byproducts and the absorption liquid are collected by a guide and discharge recovery assembly. The equipment can improve the uniformity of flue gas desulfurization, enhance the anti-blocking capability of the filter assembly and improve the stability of continuous operation of the device.
