ROTATIONAL FLOW AND SINK FLOW-COUPLING INTEGRATED SYSTEM FOR ULTRA-CLEAN DESULPHURATION AND DEDUSTING AND DESULPHURATION AND DEDUSTING METHOD THEREFOR

摘要

The present invention relates to an ultra clean desulfurization and exhaust-drying integrated system and a method of desulfurizing and exhausting the same, and more particularly, to an integrated system for performing deep desulfurization, exhaustion, and mist removal on flue gas containing sulfur dioxide and dust. The present invention discloses a rotary flow and a sink flow coupling integrated system and a desulfurization and exhausting method thereof for ultra clean desulfurization exhaust, the system comprising a spray layer (3), a slurry pond (5), and a circulation pump Flow-stream flow coupling device 4 and a vortex dust mist removing device 2. The flow- The rotary flow sink flow coupling device 4 is mounted on the upper part of the slurry pond 5 and the lower part of the spray layer 3 and the vortex dust mist removal device 2 is provided on the upper end of the column 1. The rotating flow sink flow coupling device 4 includes a plurality of rotating flow sink flow coupling units 41 and supporting columns 42 provided at the lower portion thereof and used for fixing, The rotor 41 includes a rotating current cylinder 44, a rotating current rotor 43 and a flow guiding device 45. The rotating current rotor 43 includes an inner cylinder 431 and a rotating current vane 432 , The inner diameter of the flow guide device (45) where the flue gas flows out is smaller than the inner diameter at which the flue gas flows, and the vortex dust mist removing device (2) includes a plurality of dust mist removing units, The mist removing unit includes n turbulence rotors 22 provided in the flow guiding cylinder 21 and the flow guiding cylinder 21 and the turbulence rotors 22 are all disposed on the wall of the flow guiding cylinder 21 up and down.
