High-efficiency energy-saving colored smoke plume management system

Abstract

The invention relates to a high-efficiency energy-saving colored smoke plume management system, and belongs to the technical field of smoke plume management. The system comprises gate valves 1, air-cooling heat exchangers 2, defoggers 3, a flue gas pipeline 4, air-cooling heat exchanger fans 5, an air-cooling hot air pipeline 6, air coolers 7, a cold air pipeline 8, a mixer 9, a mixed gas pipeline10 and an exhaust funnel 11. The system provided by the invention effectively utilizes air as a cold source and as a heat carrier to superheat dead steam, no water resources or other heat sources areconsumed, and the system is simple, reduced in investment and reduced in operating costs, and has broad application prospects.

Description

technical field

[0001] The invention belongs to the technical field of smoke plume control, and relates to a high-efficiency and energy-saving colored smoke plume control system. Background technique

[0002] In the steel, electric power, and coking industries, the colored plume of high-humidity flue gas is serious, the exhaust steam temperature is high, the moisture content is high, and there are corrosive substances in the gas, which has a serious impact on the environment and is one of the causes of smog. In severe cases, acid rain will be formed, leading to local corrosion.

[0003] Mechanistically, the control of the colored plume of the flue gas is to make the working point of the flue gas at the chimney outlet in the process of heat and mass transfer mixed with the atmosphere always in a superheated state, and the colored plume that does not enter the saturation line can be seen area.

[0004] In order to eliminate the white smoke plume, the existing technology main...
