Wet curtain solution dehydrator

Abstract

The invention belongs to the technical field of dehydration and drying treatment of aqueous flue gas, and discloses a wet curtain solution dehydrator. The dehydrator comprises struts, a lower water tank, a drain valve, a gas inlet, wall plates, a lower flower plate, moisture channels, wet curtain assemblies, dry gas channels, an upper flower plate, a gas outlet, an upper gas header, a concentratedsolution supply system, a dilute solution discharge system, a water spray system and an overflow pipe. According to the dehydrator, the upper half part of a tank comprises N moisture channels and (N-1) dry gas channels, which are formed by the lower flower plate, the wet curtain assemblies, the upper flower plate and the wall plates on the periphery; the water spray system is arranged at the lower half part of the tank in the dehydrator. A water spray pre-cooling and wet curtain solution dehydration integrated structure is adopted, a salt solution is fully contacted with water-containing fluegas by the wet curtain assemblies, and the dehydrator has the advantages of high dehydration efficiency, compact structure, small occupied area and wide application range, and equipment investment issaved.

Description

Technical field [0001] The invention belongs to the technical field of water-containing flue gas dehydration and drying treatment, and in particular relates to a wet curtain solution dehydrator. Background technique [0002] A large amount of water-containing flue gas will be produced in the industrial production process. For the water-containing flue gas that does not contain dust, it is generally discharged at a high altitude. For the water-containing flue gas containing dust, it generally needs to be discharged at a high altitude after purification. There is a lot of water vapor and a certain temperature. The color of the flue gas is generally “white”. When the “white” flue gas is discharged into the atmosphere, it will condense into corrosive “raindrops” after being in contact with the cold air, and fall around. , The formation of "white pollution", and a large amount of water vapor is discharged into the atmosphere, which also causes a waste of water resources. As the count...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: if the treatment equipment with better dehydration effect is selected, there are defects such as complex equipment, large investment, or energy consumption and waste of water resources; if conventional simple dehydration drying equipment is used, and There is low dehydration efficiency and cannot meet environmental protection requirements
