Compact industrial tail gas fine particle efficient removing and cooling device and method

Abstract

The invention provides a compact industrial tail gas fine particle efficient removing and cooling device and method, the device comprises a flue gas pretreatment unit and a cyclone separating unit, the flue gas pretreatment unit comprises a gravity settling chamber and a steam phase change chamber, the lower end of the steam phase change chamber is communicated with the upper part of the gravity settling chamber, wherein the steam phase change chamber is divided into a steam phase change section and a turbulence agglomeration section from bottom to top, the device adopts an integrated design of a particle pretreatment unit and the cyclone separating unit, and particularly, a steam phase change agglomeration and turbulence agglomeration treatment technology is firstly fused into the particle pretreatment unit, so that the removal of coarse particles and the agglomeration and growth of fine particles in dust-containing tail gas are realized; the cyclone separating unit adopts an axial flow type cyclone separator structure with a reflecting screen, so that the fine particle removal efficiency is effectively improved; and the device is compact in overall structure, small in occupied area and convenient to operate, and the purpose of efficiently removing fine particle pollutants in industrial tail gas in an energy-saving mode is achieved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment in terms of separation and purification in boiler equipment, and specifically belongs to a compact industrial tail gas fine particle efficient removal and cooling device and method. Background technique [0002] Energy, chemical, metallurgy, thermal power and other pillar enterprises of the national economy will emit a large amount of industrial tail gas during the production process, which will cause great harm to the atmospheric environment and human health. Among the 385 cities monitored in 2016, only 29.6% of them met the air quality standards, and the pollutant emissions mainly come from coal combustion. In response to this problem, my country's environmental protection department has formulated relatively strict legal standards. In addition, the impact of inhalable particulate matter on human health cannot be ignored. Some studies have shown that 100% of the particles with a...
