Wet desulfurizing process is that China applies most common flue gas scrubbing CO_2 technique.Wet desulphurization exiting flue gas one
As in saturation or close to saturation state wet flue gas.Wet flue gas is lower with temperature after in smoke stack emission to air
When surrounding air contacts, in flue gas diffusion process, saturation or nearly saturation wet flue gas generate condensation and condensation since temperature reduces,
The a large amount of condensing water droplets formed in flue gas generate refraction to light, scattering is called " cigarette to show white or grey
Plumage " (" the big white cigarette " that is commonly called as, " white haze ", " white plume " etc.).
Influence of the white cigarette to environment is mainly reflected in two aspects.On the one hand it is higher using wet flue gas relative humidity, contains
There are a large amount of sulfate, nitrate, sulfate, nitrate particle to enter " core " for becoming in air and adsorbing other pollutants, be
Cause a key factor of haze.On the other hand it is that spreading for plume also causes " vision dirt to the resident on power plant periphery
Dye " generates certain influence to the life of resident.
Currently, the major technique that white cigarette is administered includes flue gas, flue gas cool-down reheating and flue gas cool-down technology.Wherein,
Flue gas technology can eliminate white cigarette when environment temperature is higher, and it is not notable that white cigarette effect is eliminated when environment temperature is relatively low.Separately

Example is not limited to the scope of the present invention for illustrating the present invention.
The device that spraying cooling in a kind of desulfuration absorbing tower eliminates white cigarette, including desulfuration absorbing tower 1 are present embodiments provided,
Desulfuration absorbing tower 1 is internally provided with the first demister 11, and 11 top of the first demister is equipped with for being carried out to flue gas by cooling water
The spraying ventilating device 12 of cooling, and the water collector for collecting the cooling water after spraying, water collector connect desulfurization and inhale
Receive the first buffering pond 3 outside tower 1.
In the present embodiment, water collector is pallet 13, and 13 bottom opening of pallet simultaneously passes through pipeline and the first buffering pond 3
Connection, can make the cooling water after spray flow automatically to the first buffering pond 3 and exchange heat.
In the present embodiment, the desulfuration absorbing tower inner wall of 13 top of pallet is surrounded by for preventing spraying cooling water from bypassing
Pallet influences the baffle 14 of desulphurization system water balance downstream to desulfuration absorbing tower slurry pool.
In the present embodiment, current equalizer (not shown) is additionally provided with inside desulfuration absorbing tower 1, current equalizer is located at pallet 13
Top, the lower section of spraying ventilating device 12.
In the present embodiment, one kind in packing layer, turbosphere, bubble level or combination can be used in current equalizer.
In the present embodiment, 12 top of spraying ventilating device is equipped with for removing the second demister of droplet carried in flue gas
17。
In the present embodiment, tubular type or bundled tube, board-like, ridge type can be used in the first demister 11, the second demister 17
One kind in demister or combination are arranged in the top of spraying layer 15.
In the present embodiment, the liquid-gas ratio of 12 flue gas of spraying ventilating device spray is 0.5-3, and one layer to three layers spray can be arranged
Drenching layer.
In the present embodiment, spraying ventilating device 12 includes nozzle, and nozzle uses pressure type or rotarytype injector.
In the present embodiment, spraying ventilating device 12 buffers pond 7 by the second centrifugal pump 6, second and connects with cooling tower 5
