Harmless treatment is carried out to toxic, the pernicious gas that are discharged in production process with packed absorber or spray absorber.
Currently, to increase absorbing liquid to the assimilation effect of exhaust gas, it is common to use be dynamic wave exhaust gas treatment technology, it is so-called
Dynamic wave is exactly that circulating pump is utilized to spray a fluid column in pipeline, and exhaust gas is then blowed to fluid column, is reached after being allowed to area diffusion
To the effect of absorption, but dynamic wave absorption techniques have a fatal premise, exactly need the wind pressure of gas very big, that is, blower
Power it is sufficiently large, not so fluid column can not be dispelled, not dissipated once blowing, a ring is formed around fluid column
Shape channel, gas are just run away easily in the case where no assimilation effect, are unable to reach desired effect.
How the drawbacks of for the prior art is improved, the final stage pipeline before exhaust gas enters absorption tower by technology
Technical treatment is carried out in trunnion, the flow velocity in conjunction with this section of gas is existing much larger than the flow velocity i.e. physics of empty tower gas velocity risen in tower
Shape designs a waste gas absorption tower inlet throat atomising device, with solve in the prior art absorbing liquid and toxic, pernicious gas without
The drawbacks of method comes into full contact with.
Utility model content
To overcome the shortcomings of the existing technology, the utility model provides a kind of waste gas absorption tower inlet throat atomising device,
By the way that new device is arranged in the final stage pipeline before exhaust gas enters absorption tower, be utilized exhaust gas high-speed flow kinetic energy and
Dynamic pressure, the absorbing liquid moment that spray head is sprayed blow out mist droplet, to increase absorbing liquid and discarded contact area, improve absorption
Effect.
To realize the above-mentioned technical purpose, the utility model uses following scheme: a kind of waste gas absorption tower inlet throat atomization
Device a comprising absorption tower body is provided with air inlet pipe on the side wall of absorption tower body, and at the trunnion of air inlet pipe, one is sent
Liquid pipe is radially across air inlet pipe side wall and enters to inside trunnion, and inside trunnion, liquid pushing tube difference is upwards and lower section extends
It is provided with a upper jet pipe and a lower jet pipe, a spray head is respectively arranged in the end of upper jet pipe and lower jet pipe, in liquor charging
The end of pipe is also equipped with a spray head；The air inlet pipe is bent downwardly after penetrating to absorption tower body inside, and in air inlet pipe
Bottom be that the taper of diffusion type is arranged, and bottommost is provided with a circle tooth side, inside the absorption tower body, in air inlet
Fluid collection device is provided with above pipe, the top of fluid collection device is packing support.
Spray head on lower jet pipe and the spray head on the line and upper jet pipe between the spray head of liquor charging tube end and liquor charging pipe end
The included angle A of line between the spray head in portion is 120 degree；Spray head on lower jet pipe and the line between the spray head of liquor charging tube end and
The angle of the line between the spray head on spray head and lower jet pipe on upper jet pipe is 120 degree.
All spray heads are all towards setting outside air inlet pipe.
It is designed above the utility model has the following beneficial effects: the utility model passes through, by absorption tower body side wall
Air inlet pipe trunnion at liquid pushing tube is set, and multiple spray heads are set on liquid pushing tube, because the flow velocity of this section of gas is much larger than tower
Flow velocity, that is, empty tower gas velocity of interior rising, this technology are exactly that kinetic energy and the dynamic pressure of exhaust gas high-speed flow is utilized, and spray head is sprayed
Absorbing liquid moment blows out mist droplet, and which increases the specific surface areas of absorbing liquid, improve gas liquid interfacial area, can be very
The absorption mass transport process of this partially liq is completed in short time；The utility model, which also has both, washes exhaust gas rapid cooling, particulate matter
The effect for washing and reducing air-flow pulse, particularly with temperature height, the big exhaust gas of dust, effect is clearly.
