Description

Technical Field

[0001] The utility model relates to the technical field of flue gas desulfurization and denitrification, in particular to an environment-friendly integrated tower for flue gas desulfurization and denitrification. Background Art

[0002] The flue gas of industrial power station boilers, industrial boilers, waste incinerators, etc. contains high concentrations of sulfur dioxide and nitrogen oxides, and needs to be treated for desulfurization and denitrification. In terms of denitrification, there are problems such as insufficient space and insufficient boiler furnace temperature in the denitrification treatment of flue gas from power station boilers, industrial boilers, waste incinerators, etc., and the wet denitrification process is applicable to denitrification. At present, most of the wet flue gas desulfurization devices applied in industry use empty tower spray towers, and most of the wet flue gas denitrification devices applied in industry also use empty tower spray towers.

[0003] An environment-friendly integrated tower for flue gas desulfurization and denitrification disclosed in the publication number CN211274186U, although it includes a spray tower, an air inlet pipe is installed on one side surface of the spray tower, and one end of the air inlet pipe penetrates through the spray tower and is connected with a gas distribution plate in a through manner, and a liquid inlet pipe is installed on the other side surface of the spray tower; in the utility model, there are two spiral spray pipes in the spray tower. By starting the water pump, the spray material can be synchronously introduced into the two spiral spray pipes from the liquid inlet pipe, so that the spray material passes through the liquid spray holes equidistantly arranged on the bottom surfaces of the two spiral spray pipes and is evenly and densely sprayed in the spray tower, making the spray material more dispersed. Among them, one end of the air inlet pipe penetrates through the spray tower and is connected with the gas distribution plate below the two spiral spray pipes, and a plurality of air guide holes are arranged on the top surface of the gas distribution plate, so that the gas carrying desulfurization and denitrification is dispersed and filled into the spray tower, making the contact between the spray material and the gas carrying desulfurization and denitrification more sufficient.

[0004] When denitrifying the flue gas, the mixing of the flue gas and the spray water is not fast enough, and the spray water denitrifies the flue gas slowly, resulting in a decrease in the treatment speed of the flue gas, and the treated flue gas will directly flow to the outside. There are smoke blocks in the flue gas flowing to the outside, and the smoke blocks will have an impact on the environment. Summary of the Utility Model

[0005] In view of the above-mentioned drawbacks of the prior art, the utility model provides an environment-friendly integrated tower for flue gas desulfurization and denitrification.
