Abstract

The invention relates to a wet smoke plume eliminating system. The wet smoke plume eliminating system comprises a first cooling subsystem, a second cooling subsystem and a heater which are successively arranged between a smoke outlet of a desulphurization tower and a chimney; the first cooling subsystem comprises a first circulating water loop, the first circulating water loop is provided with a spraying apparatus and a circulating water tank, the second cooling subsystem comprises a fluoroplastic heat exchanger communicated with the spraying apparatus; the circulating water tank is communicated with the first cooling subsystem and the second cooling subsystem and used for collecting condensed water and sprayed water and providing circulating water circularly entering the spraying apparatus along the first circulating water loop; and the water smoke plume eliminating system also comprises a water storage tank, and the water storage tank is communicated with an overflow opening of the circulating water tank. By adopting the wet smoke plume eliminating system, water can be effectively extracted from smoke, the wet smoke plume phenomenon can be completely eliminated, the environment is purified, and the water use efficiency of a power plant can be increased at the same time.

Description

technical field [0001] The invention relates to the technical fields of chimney control, water saving and energy saving, in particular to a wet smoke plume elimination system. Background technique [0002] Since the outlet of the chimney of the coal-fired power plant is saturated wet flue gas, which is directly discharged into the atmosphere through the chimney, there will be a phenomenon of "big white smoke" in the wet plume, which will greatly reduce the recognition of the surrounding residents for the near-zero emission of the power plant. Some residents made relevant claims, and some local governments such as Shanghai issued the "Emission Standards of Air Pollutants for Coal-fired Power Plants" (DB31 / 963-2016) on January 29, 2016, requiring that "coal-fired power boilers Smoke temperature control and other effective measures should be taken to eliminate gypsum rain and colored plumes.” [0003] As we all know, my country is one of the countries with the poorest water re...
