Specific embodiment
It is real below in order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention
Example combination attached drawing is applied to be specifically addressed to provided by the invention.
It please refers to shown in Fig. 1 and Fig. 2, shows a kind of stalk emission-control equipment, the reactor tank including filling weak lye
1, which is equipped with air inlet 11 and gas outlet 12.Exhaust gas decentralized institution 2, exhaust gas decentralized institution 2 are equipped in reactor tank 1
Be connected with air inlet 11, by exhaust gas decentralized institution 2 will enter reactor tank 1 in exhaust gas disperse, expand exhaust gas with it is weak
The contact area of lye improves reaction efficiency, to realize exhaust gas after straw burning so that exhaust gas reacts rapidly with weak lye
Fully absorb neutralization.Further, it is equipped with spray channels 3 at the gas outlet 12 of reactor tank 1, is equipped with different height in spray channels 3
Multiple spraying mechanisms 4 of degree, the lower end of reactor tank 1 are equipped with liquid pumping hole 51, and liquid pumping hole 51 is connected with drawing liquid pump 5, and drawing liquid pump 5 goes out
Liquid mouth is connected by bifurcated passage 6 with multiple spraying mechanisms 4, is just directly discharged in air after reacting originally with weak lye
Exhaust gas handled again through spraying mechanism 4, neutralization reaction occurs again, so that the exhaust gas being discharged into air is more environmentally-friendly.Meanwhile
The setting of drawing liquid pump 5, so that the constancy of volume of the weak lye in reactor tank 1, in 1 bottom of reactor tank, another part exists a part
In spraying mechanism 4, drawing liquid pump 5 returns to 1 bottom of reactor tank by spraying mechanism 4 from 1 bottom drawing liquid of reactor tank, realizes reactor tank
Weak lye in 1, which recycles, to be neutralized, and avoiding weak lye from additionally adding to spraying mechanism 4 causes the weak lye in reactor tank 1 excessive, causes
Waste causes weak lye to overflow reactor tank 1 what is more.
Specifically, exhaust gas decentralized institution 2 includes the spray head 21 and connecting tube 23 with internal cavities, one end of connecting tube 23
It is connected to the air inlet 11 of reactor tank 1, the other end of connecting tube 23 and the connects with the internal cavities of spray head 21, if spray head 21 is equipped with
Dry dispersion hole 22, the connects with the internal cavities of dispersion hole 22 and spray head 21 are made by being provided with the spray head 21 of several dispersion holes 22
Exhaust gas by not being directly to be discharged near air inlet 11 after the air inlet 11 of reactor tank 1, cause to get lodged in air inlet in exhaust gas centralized
Mouthfuls 11, be unfavorable for reacting for exhaust gas and weak lye, but by the connecting tube 23 of exhaust gas decentralized institution 2 to each dispersion hole 22 after
It discharges again, so that the contact area of exhaust gas and weak lye increases, accelerates neutralization of the weak lye to exhaust gas.In the present embodiment, give up
The setting of gas decentralized institution 2 can be submerged in reactor tank 1 by weak lye, but the height of weak lye is not above reactor tank 1
Air inlet 11 prevents weak lye from flowing out to another device from reactor tank 1.
In order to keep exhaust gas and reacting for weak lye more abundant, the dispersion hole 22 in exhaust gas decentralized institution 2 is arranged in spray head
21 lower surface, the i.e. opening direction of dispersion hole 22 can be such that exhaust gas sprays towards the bottom of reactor tank 1 towards the bottom of reactor tank 1,
Constantly rise in weak lye again, the reaction contact time of exhaust gas and weak lye extends, so that the sulfur dioxide in exhaust gas is filled
Divide and neutralizes.
Specifically, spraying mechanism 4 includes the internal cyclic annular circle body 41 with pipeline, cyclic annular circle body 41 is arranged in spray channels
On 3 inner wall, the side of cyclic annular circle body 41 is equipped with inlet 42, and inlet 42 is connected to bifurcated passage 6, sets on bifurcated passage 6
There is the liquid flowing valve 52 of controllable feed liquor, several spray apertures 43 is evenly provided on cyclic annular circle body 41, exhaust gas is in spray channels 3
Neutralization reaction occurs with weak lye again under the action of spraying mechanism 4 of different height, so that the sulfur dioxide in exhaust gas is more
It is discharged into air after the secondary processing that is absorbed, discharge standard can be reached, environmental protection.
In addition, the structure of the junction of reactor tank 1 and spray channels 3 is pyramidal structure 13, exhaust gas can be made to be concentrated through spray
Channel 3 is drenched, the weak lye set with spray reacts more abundant.
In addition, the air inlet 11 in reactor tank 1 is connected with surge tank 7, reactor tank 1 and surge tank 7 pass through ventilation pipe 71
Connection, surge tank 7, which is equipped with exhaust gas inlet 72, leads to exhaust gas since the severe degree of titanium white continuous acidolysis reaction is different
The speed of discharge is also different, and the controllable speed into the exhaust gas in exhaust-gas treatment reactor tank 1 of setting surge tank 7 makes exhaust gas
Reactor tank 1 is stably entered, also ensures that exhaust gas can be neutralized sufficiently with the weak lye in reactor tank 1.It is also connected on surge tank 7
Air blower 73 avoids having exhaust residual in surge tank 7, and exhaust gas is made to fully enter reactor tank 1 and weak lye neutralization.
The above is only preferred embodiments of the present invention, are not intended to limit the implementation manners and the protection scope of the present invention, right
For those skilled in the art, it should can appreciate that and all replace with being equal made by description of the invention and diagramatic content
It changes and obviously changes obtained scheme, should all be included within the scope of the present invention.
