This internally circulating wet flue gas desulfurization tower adopts said structure that flue gas is vulcanized more fully, the slurrying pond contacts with flue gas with the lime stone slurry in the slurries pond is capable of circulation, improve utilization rate, saved water resource, the calcium sulfate of pond, slurries pond bottom precipitation enters sedimentation basin, can be utilized once more, so this desulfurizing tower takes off the harmful components that both can deviate from the flue gas, fall dirty the reduction of discharging, conserve water resource effectively generates new utilizable product simultaneously again.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail:
Fig. 1 is the structural representation of internally circulating wet flue gas desulfurization tower.
The specific embodiment
A kind of internally circulating wet flue gas desulfurization tower, comprise column foot 10 and body of the tower 20, body of the tower 20 inside are provided with desulphurization system 30, in the upper end of body of the tower 20 is exhanst gas outlet 21, exhanst gas outlet 21 places are provided with demister system 40, in the lower end of body of the tower 20 is gas approach 22, and air inlet 22 is downward tangential direction with body of the tower 20.In the bottom of body of the tower 20 is slurries pond 1, and the top in slurries pond 1 links to each other with fluid infusion system 70, and the bottom in slurries pond 1 links to each other with soot cleaning system 50, also is provided with pulping system 60 in the outside of body of the tower 20, and pulping system 60 links to each other by spray circulating pump 33 with desulphurization system 30.
Described desulphurization system 30 is for being provided with desulfurization pipeline 31 on body of the tower 20 outer walls, spray equipment 32 links to each other with desulfurization pipeline 31 and enters the inside of body of the tower 20, and this spray equipment 32 is 2～8 from top to bottom, and what this spray equipment sprayed is annular vaporific gas.
Described demister system 40 is for being positioned at the circulation demister 41 at exhanst gas outlet 21 places.
Described pulping system 60 is formed by stirring pump 61 and slurrying pond 62, and fluid infusion system 70 is made up of fluid infusion pump 71 and fluid infusion pond 72, and the upper end in fluid infusion pond 72 communicates with slurrying pond 62.
Described soot cleaning system 50 is made up of deashing pump 51 and sedimentation basin 52, and wherein the inlet of deashing pump 51 is connected with pipeline with the bottom of column foot 10, and the outlet of deashing pump 51 links to each other with sedimentation basin 52 usefulness pipelines.
Its operation principle is: the body of the tower 20 of desulfurizing tower is cylindrical tower body, and flue gas enters in the tower by gas approach 22, and flue gas is cut sth. askew and entered downwards, and this kind structure helps weakening the reflux in tower vortex, reduces crushing, prolongs gas-liquid contact time, prevents that slurries from flowing backwards.Lime stone and water are made lime stone slurry with the agitator stirring in slurrying pond 62, fluid infusion pump 71 is input to water in the fluid infusion pond 72, water in slurrying pond 62 is low excessively, water in the fluid infusion pond 72 keeps the skin wet in slurrying pond 62 by the passage on top, spray circulating pump 33 is sent into the lime stone slurry that makes in the desulfurization pipeline 31, by spray equipment 32 annular spray in tower, the lime stone slurry of ejection contacts with the hot flue gas that adverse current makes progress the chemical absorbing reaction takes place, and be cooled, lime stone slurry absorbs sulfur oxide and other acidic materials from flue gas, sulfur oxide again with calcium carbonate reaction, form calcium sulfite, under the acting in conjunction of centrifugal inertial force and gravity, grey water droplet after the reflection constantly is thrown to the tower body inwall, thereby by the washing of the lime stone slurry of ejection in the spray equipment 32, flows to the slurries pond 1 of tower body bottom through the tower body wall, stir lime stone slurry that pump 61 makes simultaneously and be delivered to the slurries pond 1 of tower bottom, keep the height in slurries pond 1, the position; The calcium sulfate that the bottom in slurries pond 1 is constantly precipitated is in deashing pump 51 is discharged to sedimentation basin 52, and this calcium sulfate can be utilized once more.Flow to into circulation demister 41 by the flue gas after the complete desulfurization, gas enters atmosphere from exhanst gas outlet 21.Contact with flue gas owing to circulating repeatedly by spray circulating pump 33 at desulfurizing tower sodalime stone slurries, not only the water source is saved in recycling, and has generated byproduct calcium sulfate, has reduced production cost.
