The utility model relates to a removing device of coal fired power plant flue gas desulfurization and dust removal integration is equipped with the increase board that flow equalizes in absorption tower entry top, flow equalizes to set up 2~5 layers between the 1.5m~3m of increase board top and spray the layer, and the interval that sprays every layer on layer sets up 1~the 2 layer of ring of enlarging in the middle of spraying the layer between 1.8~2.5m, spray layer top in the superiors and set up the pipe precipitator. The beneficial effects of the utility model are that: the increase board that flow equalizes has increased the contact time of gas -liquid, provides more dissolving machine meetings at the absorption region to increase desulfurization efficiency, it is more even to make the gas -liquid distribute, avoids the difference of regional desulfurization of different liquid -gas ratios and dust collection efficiency to the device's integrated desulfurization dust collection efficiency has been improved. The volume of spraying the thick liquid has been practiced thrift to desulphurization unit's liquid -gas ratio, has reduced the volume of spraying the number of piles, need not additionally to increase large -scale dust collector such as wet -type electrostatic precipitator, greatly improvement project volume and operation cost is reduced, the transformation time limit for a project has been shortened.
