Device capable of eliminating white smoke

Abstract

The invention discloses a device capable of eliminating white smoke. The device comprises a heat exchanger, a desulphurization wet-type electrostatic deduster, and a condensation device; the heat exchanger is used for cooling high temperature smoke introduced into the heat exchanger, and heating smoke discharged from the condensation device; the heat exchanger is arranged in a chimney; the desulphurization wet-type electrostatic deduster is connected with the heat exchanger, and is used for desulphurization dedusting and humidity reducing temperature reducing treatment of smoke discharged fromthe heat exchanger; the condensation device is connected with the desulphurization wet-type electrostatic deduster, and is used for humidity reducing temperature reducing treatment of smoke discharged from the desulphurization wet-type electrostatic deduster; the heat exchanger is arranged in the chimney, so that temperature reduction of high temperature smoke is realized, and drying of smoke tobe discharged is realized, and energy is saved; and in addition, the desulphurization wet-type electrostatic deduster and the condensation device are used for temperature reducing and humidity reducing, so that water steam content of smoke is reduced effectively, and white smoke elimination effect is achieved.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a device for eliminating white smoke. Background technique [0002] In the existing flue gas purification and treatment process, wet desulfurization or wet electrostatic precipitator technology is usually used. Although this technology can remove most of the harmful substances in the flue gas, it greatly increases the water vapor concentration of the flue gas, which not only consumes water resources, and it is easy to form smog when the temperature is low. [0003] At present, the core principle of eliminating white smoke is to allow the flue gas and the water vapor in it to diffuse into the air before the temperature drops below the dew point temperature of water vapor during the mixing, cooling and diffusion process of the flue gas discharged from the chimney with the air. middle. [0004] Therefore, dehumidifying and heating the flue gas is the physical basis for ...

AI Technical Summary

Problems solved by technology

[0004] Therefore, dehumidifying and heating the flue gas is the physical basis for eliminating white smoke. Commonly used methods include: condensation heat transfer method, self-smoke heat transfer method, electric defogging method, mixed drying method, etc., but the above methods are not The white smoke cannot be completely eliminated, or the white smoke cannot be maintained for a long time, etc.
