Sulphur area, fully breaks former flue gas, forms multiply shunting flue gas and is contacted with liquid；And there is provided can be around fix bar in fairing
Spacing between the cylindrical conduit of rotation, and adjacent two pipeline 23 is 1cm~10cm, can carry flue gas flow rate at pipeline gap
Height, gas-liquid two-phase interfacial turbulence is strengthened, and air-film thickness is thinned and improves mass transfer rate coefficient, and fairing top is formd
One layer of turbosphere, further increases mass transfer rate coefficient；The increase of cigarette speed can slow down drop decrease speed simultaneously, thus can make slurry
Liquid increased resident time in desulfurizing tower, increases soak time, reaches the purpose for improving desulfuration efficiency.
(2) bottom of towe of the present invention is connected with alkali lye pond, and the alkali lye pond is arranged at outside desulfurizing tower, is realized outside the tower of desulfurizing tower
Precipitation, in the work cleared up alkali lye sediment, only need to enter accommodating operation, you can efficiently solve desulfurization outside tower
The problem of tower needs periodic cleaning.And it is divided into sedimentation basin and circulatory pool, a side using ceramic filter plate in alkali lye pond
Face can be filtered the alkali lye with flue gas particle by ceramic filter plate, be divided into the precipitated liquid with flue gas particle be deposited to it is heavy
Shallow lake bottom of pond, and discharged by the sewage draining exit of sedimentation basin, separation cleaning is very convenient, and on the other hand, the alkali lye after filtering is being followed
In cisterna ambiens, achievable sodium solution can be with recycled for multiple times, and the alkali lye of circulation is free of flue gas particle, is not susceptible to pipeline and spray
The blocking of drenching layer, reasonable in design with simple in construction, easy to use, it is easy to operate, the advantages of service life is long.
