White smoke removal device for smoke plume

Abstract

The invention provides a white smoke removal device for smoke plume. The device comprises a smoke plume separation tower, a smoke inlet is formed in the lower side of the smoke plume separation tower,and a smoke outlet is formed in the top of the smoke plume separation tower; a smoke inlet chamber, a condensation chamber and a smoke exhaust chamber are formed in the smoke plume separation tower from bottom to top in sequence; several condensation row tubes are longitudinally arranged in the condensation chamber, a smoke flow channel is formed between every two adjacent condensation row tubes,the lower ends of the smoke flow channels extend into the smoke inlet chamber, the upper ends of the smoke flow channels extend into the smoke exhaust chamber, and swirl vanes are arranged in each smoke flow channel separately. By means of the white smoke removal device, the smoke flow channels are arranged among the condensation row tubes, and the swirl vanes are arranged in the smoke flow channels and utilized for swirling dust-containing mist at high speed to form airflow rotatably rising; the dust-containing mist in the airflow forms dust-containing droplets when being in contact with thecondensation row tubes, the dust-containing droplets flow downwards along the surfaces of the condensation row tubes, the effect of liquid film dust removal is achieved, the concentration of dust inthe smoke and the content of moisture in the smoke are reduced, and the white smoke removal effect for the smoke plume is good.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a smoke plume whitening device. Background technique [0002] At present, the flue gas of most domestic coal-fired power plants, steel plants or other chemical industries has been wet desulfurized before being discharged, and the temperature of the flue gas has dropped to 45°C to 55°C. At this time, the flue gas is usually saturated wet smoke The flue gas contains a large amount of water vapor, and the water vapor contains more soluble salts, SO3, gel dust, fine dust, etc. (all of which are the main components of smog). If the flue gas is directly discharged from the chimney and enters the ambient air with a lower temperature, since the saturated humidity of the ambient air is relatively low, the water vapor in the flue gas will condense to form a wet plume during the temperature drop of the flue gas, causing damage to the atmosphere. The p...

AI Technical Summary

Problems solved by technology

Among them, the condensation of saturated wet flue gas after desulfurization determines the condensation and precipitation effect of flue gas water vapor, which is an important link in the plume whitening system. Higher, the effect of condensation and precipitation of flue gas and the effect of flue gas dewhitening need to be strengthened
