Abstract

The invention provides a flue gas desulfurization and dust-whitening integrated device, comprising a desulfurizing tower, a whitening device communicated with a flue gas outlet of the desulfurizing tower, and a wet electrostatic precipitator which is arranged on the top of the whitening device and is communicated with the whitening device, wherein the whitening device comprises a device shell fixedly arranged above the desulfurizing tower, a water collector arranged in the device shell, and a spray device arranged above the water collector; a water collecting hole is formed in the device shell, and is communicated with a water collecting pipe; the water collecting pipe is communicated with a water cooling tower by a water collecting pipeline; the water cooling tower is communicated with a sedimentation tank; the upper part of the sedimentation tank is connected with a spray pipeline by a spray pump; the spray pipeline is communicated with the spray device; the bottom of the sedimentation tank is connected with a desulfurization pulping system by a sewage pump. After the device is used, the aim of whitening flue gas is achieved; spray water can be separately recycled, and water removed from the flue gas can be also recycled so as to be used for the desulfurization pulping system, so that the aim of saving water is achieved.

Description

technical field [0001] The invention relates to an integrated device for flue gas desulfurization and white dust. The process device is suitable for whitening or whitening of wet flue gas generated in industrial production, especially for sintering in steel mills, boiler power generation, and garbage incineration. Whitening reduction or de-whitening when flue gas discharge using wet desulfurization process. Background technique [0002] In recent years, with the country's strict requirements on energy conservation, emission reduction and emission indicators, all walks of life have continuously taken measures to research new technologies, develop new processes, and manufacture new equipment, all of which are actively installed and put into use. After several years of hard work, some enterprises can meet the requirements of national discharge standards in terms of dust, SO2, sewage and other discharge indicators, which has greatly improved the environment. [0003] But what f...
