Abstract

The invention provides a colored smoke plume removal system and application, and belongs to the field of colored smoke plume treatment. The colored smoke plume removal system comprises a dust removal device, a circulating water cooling device, an ammonia desulfurization tower, a spraying device, a condensation separation device, a demisting device and a gas-liquid mixed heating device which are sequentially arranged in the flowing direction of smoke; a heating medium water outlet of the gas-liquid mixed heating device is communicated with a refrigerant water inlet of the circulating water cooling device; and a refrigerant water outlet of the circulating water cooling device is communicated with a heat medium water inlet of the gas-liquid mixed heating device to form a closed loop. According to the colored smoke plume removal system, conversion circulation of refrigerant water and heating medium water can be achieved while condensation is conducted firstly and then hot removal is conducted on colored smoke plume, so that circulating water systems do not need to be established respectively, the operation cost is reduced, water resources are saved, meanwhile, smoke heat energy can be recycled, and the flue gas temperature can be reduced, ammonia gas can be absorbed, secondary smoke plume is prevented, and the removal effect of the colored smoke plume is improved.

Description

technical field [0001] The invention relates to the technical field of colored plume treatment, in particular to a colored plume removal system and its application. Background technique [0002] The colored smoke plume is the saturated flue gas discharged from the chimney, which is affected by the temperature drop, causing some vaporous water and pollutants in the flue gas to condense and form mist water vapor at the chimney outlet, and the mist water vapor will vary depending on the background color of the sky and Subtle changes in color due to reasons such as sky lighting and viewing angles form colored plumes. The colored plume contains nitrogen oxides, various smoke particles, S0 2 Aerosol, NH 3 Direct discharge of pollutants such as aerosols and ultrafine crystalline salt particles will cause smog and disturb the lives of surrounding residents, so it is necessary to remove the colored plume. [0003] At present, the method of first condensation and then heating is ma...
