Specific embodiment
The present invention is further elaborated below in conjunction with attached drawing:
Embodiment 1: 4 level of helical blade type even gas distribution device frame is welded in the absorption tower wall 1 on absorption tower, helical blade
Formula even gas distribution device frame 4 is vertically mounted helical blade type even gas distribution pipe 5 in absorption tower, and flue gas enters helical blade type
The strong mass transport process that the Turbulent Mixing of gas, drop, particle is formed when even gas distribution pipe 5, passes through sufficiently connecing for gas-liquid-solid three-phase
It touches, quickly complete mass transfer, heat transfer, trapping, separation.Spray system 2 above helical blade type even gas distribution device can make spray liquid
Body equably covers each helical blade type even gas distribution pipe 5, and the spray system 2 below helical blade type even gas distribution device can rise
To pre-washing, dedusting, prevent even gas distribution device dust stratification and gas-cooled effect.
