Problems solved by technology
[0003] One of the common methods of centralized flue gas dewhitening in China is to use a cooling tower to condense and cool the flue gas, and introduce the desulfurized flue gas into the circulating water cooling tower. It has a certain washing effect, but the heat and mass transfer coefficient of the traditional device is low, which can only reduce the pollutant discharge to a certain extent, the dewhitening effect is poor, and the consumption of spray water is large, and the subsequent treatment of spray water is heavy. , not conducive to cost reduction

The invention provides flue gas desulfurization, denitrification and white smoke removal equipment, which comprises a dust remover, wherein the rear end of the dust remover is connected with the bottom end of a desulfurization and denitrification tower through a pipeline, the top end of the desulfurization and denitrification tower is connected with a booster pump through a pipeline, the other endof the booster pump is connected with the top end of a white smoke removal tower, and the white smoke removal tower comprises a flow guide outer barrel, an exhaust inner barrel, a water storage groove, an atomizing nozzle, an atomizing baffle and a spiral baffle. According to the invention, desulfurized and denitrified flue gas is pressurized through a booster pump and then forms high-speed airflow through an atomizing nozzle to be sprayed out to impact an atomizing baffle, so that a cooling liquid is atomized into small-particle water mist so as to increase the contact area between the fluegas and the cooling liquid improve the heat conduction efficiency of the flue gas and the cooling liquid, accelerate the condensation and separation of saturated steam and soluble salt in the flue gasand improve the white smoke removal effect; and the atomized cooling liquid is collected through a spiral baffle and drips to the lower side through a surface leaking opening to form a spraying effect, and heat exchange with the flue gas is conducted again so as to further improve the white smoke removal effect, so that good development prospects are realized.
Description
technical field [0001] The invention relates to the field of industrial flue gas treatment, in particular to a flue gas desulfurization, denitrification and whitening equipment. Background technique [0002] In order to control smog, the national environmental protection standards have been continuously improved, and ultra-low transformation has been implemented. At present, 93% of ultra-low emission units adopt wet desulfurization, and the flue gas after wet desulfurization is 45-55 ℃, and the water vapor is saturated; The flue gas is exhausted into the atmosphere, and the temperature of the flue gas is further reduced to the ambient temperature. After the water vapor is supersaturated, it condenses and precipitates, forming a "white smoke" phenomenon. The white smoke absorbs SOX and NOX in the flue gas and becomes acidic, and falls to the ground to form acid rain or gypsum rain; the "white plume" floating in the atmosphere evaporates and dries, and the salt is analyzed and...
