Quenching device for processing smoke generated by burning garbage and smoke processing system thereof

Abstract

The invention relates to a quenching device for processing smoke generated by burning garbage and a smoke processing system thereof. The quenching device is provided with an inlet pipeline, a quenching pipeline, an outlet pipeline, a spray cooling controller and a temperature measurer, wherein a first sprayer is installed on the inlet pipeline, and the water spraying quantity of the first sprayer is fixed; a second sprayer is installed on the outlet pipeline, and the water spraying quantity of the second sprayer is regulated and controlled by the spray cooling controller according to the temperature data fed back by the temperature measurer; the quenching pipeline is communicated with an ash bucket arranged below the quenching pipeline; the smoke processing system is provided with an acid removing tower and a bag-type dust remover; the outlet pipeline of the quenching device is communicated with an inlet end of the acid removing tower; and the temperature measurer is installed on a pipeline that the acid removing tower is connected with the bag-type dust remover. By adopting the quenching device and the smoke processing system of the invention, ash can not be deposited on an inner wall of the acid removing tower easily, the maintenance cost is lower, and the quenching device has simple installation and lower manufacturing cost.

Description

technical field [0001] The invention relates to a quenching device and a flue gas treatment system for waste incineration flue gas treatment, which are mainly used in the flue gas treatment of rubbish incineration. Background technique [0002] At present, the most common method of garbage disposal is garbage incineration, using garbage incinerators to incinerate municipal solid waste, and the heat generated can be used to generate electricity. However, the waste incinerator will produce a large amount of flue gas during the incineration process, and the flue gas contains acid gas (SO 2 , HCL, HF, etc.), dioxin-like organic pollutants, heavy metals (Cd, Hg, Pb, etc.), direct discharge into the atmosphere will cause local acid rain, greenhouse effect, etc., and cause serious pollution to the atmospheric environment. [0003] In order to remove the pollutants in the flue gas, the flue gas desulfurization process is generally used at the tail of the boiler. At present, the sem...
