Abstract
The invention relates to a device for efficiently getting water, eliminating white smoke and cooperatively removing contaminants and a working method for the device. The device comprises a draught fan, a deep waste heat recycling system, a desulfurization system, an efficient condensing and water-getting system, a smoker re-heating and white smoke eliminating system, a chimney and a heat medium water circulating pump, wherein the efficient condensing and water-taking system comprises a condensing and water-getting heat exchange system, a condensing water circulating pump and a mechanical ventilating cooling tower; the condensing and water-getting heat exchange system is arranged at an outlet flue of the desulfurization system; the condensing and water-taking heat exchange system is connected with the condensing water circulating pump; the condensing water circulating pump is connected with the mechanical ventilating cooling tower; the condensing and water-taking heat exchange system isconnected with the mechanical ventilating cooling tower; the deep waste heat recycling system is connected with the heat medium water circulating pump; the heat medium water circulating pump is connected with the smoker re-heating and white smoke eliminating system; and the deep waste heat recycling system is connected with the smoker re-heating and white smoke eliminating system. The device is used for recycling a great deal of water in smoke, greatly saves water consumption amount of the desulfurization system, eliminates visual pollution of white smoke plume, and effectively reduces anti-corrosion grade of the chimney.
Description
technical field [0001] The invention relates to a kind of high-efficiency water extraction and white smoke synergistic removal of SO 3 A device and method for pollutants such as , Hg, aerosol, etc., especially a kind of high-efficiency water intake and white smoke collaborative removal of pollutants device and its working method. Background technique [0002] With the stringent environmental emission requirements, in order to achieve ultra-low desulfurization emissions, most power plants need to remove the rotary GGH with a large air leakage rate. Flue gas temperature decreases, which leads to increased water consumption of the desulfurization system, corrosion of the outlet flue, internal corrosion of the chimney, and visual pollution of the white "smoke plume". [0003] In addition, our country is a country with a serious shortage of water resources and an uneven distribution of water resources. The shortage of water resources has become a serious problem restricting the ...
