Dust removal, desulfurization and white smoke removal integrated method

Abstract

The invention provides a dust removal, desulfurization and white smoke removal integrated method. An adopted device comprises two Roots blowers, a desulfurizing agent bin, a primary purification unit,a secondary purification unit, an induced draft fan, a chimney and a compressed air unit, wherein one Roots blower blows a desulfurizing agent in the desulfurizing agent bin into the primary purification unit; coke oven coal charging flue gas reacts with the desulfurizing agent in the primary purification unit to complete desulfurization, enters the secondary purification unit after being cooledand whitened, and is discharged into the chimney through the induced draft fan after secondary desulfurization and dust removal are completed in the secondary purification unit. According to the device, cooling and desulfurization are integrated into the primary purification unit, secondary desulfurization and dust removal are integrated into the secondary purification unit, the dust removal, desulfurization and white smoke removal functions of coke oven coal charging flue gas can be achieved at the same time, the number of equipment is reduced, the occupied area is reduced, and the purchase,use and maintenance cost is greatly reduced; in addition, the device adopts a set of pipelines and is simple in arrangement, so that full-automatic control can be realized, and flue gas leakage is noteasy to cause.

Description

technical field [0001] The invention relates to the field of coke oven coal charging flue gas treatment equipment, in particular to an integrated method of dust removal, desulfurization and dewhitening. Background technique [0002] With the speed of industrial development and the continuous improvement of people's living standards, the types of materials required for production and life are becoming more and more abundant, and the proportion of chemical products in it is also increasing. However, the flue gas discharged from the production of chemical enterprises, especially the flue gas from coke oven coal charging, will contain a large amount of water vapor or gaseous viscous substances, accompanied by dust and sulfide. If it is directly discharged into the atmosphere, it will cause damage to the environment. , threaten people's health and affect the normal growth of crops. [0003] At present, the purification process of coke oven coal charging flue gas is generally as ...
