Diameter ratio be 0.1~0.3, retaining collar diameter 11~25mm bigger than outer barrel diameter, inner cylinder is higher by 5~20cm compared to outer barrel.
As preferred：The adjacent inner barrel blade overlapping area of the inner cylinder swirl vane is single inner cylinder swirl vane
5%~11%, the adjacent outer barrel blade overlapping area of the outer barrel swirl vane is single outer barrel swirl vane projected area
5%~11%.
As preferred：Demisting dust pelletizing system and absorption tower outlet are followed successively by the spray system.
As preferred：The end of the central tube is welded with shrouding.
The beneficial effects of the utility model are：
1st, it is favorably improved efficiency of dust collection.Because flue gas and sprayed slurry contact area are bigger, more abundant, flue gas temperature is mixed
Degree can be reduced rapidly.Meanwhile, after flue gas is spun up, kinetic energy increase, according to the equation of gas state, gas temperature also can
Decrease.Cigarette temperature drop is low to be helped to strengthen the adsorption capacity of dust in flue gas, after adsorbing powder dust condenses, it is easier to removed by dedusting
Mist system is removed.
2nd, desulfuration efficiency is effectively improved.Flue gas can be produced by this purifier and be rotated and be accelerated, and flue gas flows through inner cylinder
Direction of rotation and flow through outer barrel direction of rotation on the contrary, force flue gas be in unordered turbulence state.The slurries of absorption tower spray
Under the impact of unordered turbulent flow flue gas, secondary-atomizing rate is improved, reaction surface area increase, the hybrid reaction of slurries and flue gas
More fully, so as to effectively improve desulfuration efficiency.
3rd, easy to implement, improvement project amount is few, and energy consumption is low.For retrofitted unit, installation of the present utility model is very convenient,
Improvement project amount is few, is not required to increase slurries spray flux, therefore is not required to newly-increased circulating pump, and absorption tower system operation energy consumption is low.
4th, system reliability is high, and maintenance is convenient.The utility model is stainless steel structure, and component strength is good, and stability is high, peace
System is reliable and stable under the effect of flue gas load after the completion of dress.Stainless steel surfaces are smooth, and impeller clearance is big and the moment is by slurries
Rinse, be not easily blocked, artificial cleaning is also more convenient during maintenance.
