2. the tail gas after being absorbed by liquid absorption in first order absorption scrubbing tower is passed through two grades of absorption scrubbing towers by flue, The absorbing liquid circulated simultaneously in liquid pool is also passed into two grades of absorption scrubbing towers, and absorbing liquid is revolved by two grades of absorption scrubbing tower high speeds Fully contacted with tail gas after the shower nozzle turned is atomized;
3. the tail gas after being absorbed by liquid absorption in two grades of absorption scrubbing towers is passed through three-level by flue and absorbs scrubbing tower, Circulate the absorbing liquid in liquid pool simultaneously to be also passed into three-level absorption scrubbing tower, absorbing liquid passes through three-level and absorbs the rotation of scrubbing tower high speed Fully contacted with tail gas after the shower nozzle atomization turned;
4. the gas that three-level is absorbed after being absorbed by liquid absorption in scrubbing tower is passed through in turbulence washing tower by flue, is entered One step removes HS, HF, fluorine silica gel in tail gas;
5. the tail gas after turbulence washing tower processing is passed through multiple baffle demister by flue, and one is entered in multiple baffle demister Step removes mist, bubble and the smokeshade in tail gas;
6. multiple baffle demister processing after tail gas is introduced into by air-introduced machine in coke filter, wherein multiple baffle demister with The particle in wire gauzee filter removing tail gas is added between air-introduced machine, flue gas is further removed into the tail gas in coke filter In particle.
7. the tail gas after processing is introduced smelly tower at three-level by the tail gas after coke filter processing by air-introduced machine, except deodorizing Taste, the gas after processing is discharged into air by chimney;
It is preferred that, after being washed in described first order absorption scrubbing tower, two grades of scrubbing towers, three-level scrubbing tower and turbulence washing towers Liquid be collected into collection washing lotion pond and clarify by pipeline.
It is preferred that, the liquid clarified in described collection washing lotion pond is passed through in circulation liquid pool and recycled as absorbing liquid, collects Saturated solution and sediment in washing lotion pond are admitted to ball mill grinding, and the material after grinding is used to produce calcium superphosphate.
It is preferred that, absorbing liquid is the limewash that PH is 8-13.
Present invention process is simple, and vent gas treatment effect is good, improves efficiency, not only solves the gas such as HS, HF in tail gas Solution absorption, HS and the stink absorption problem of other sulfide are solved again, while multiple during solving vent gas treatment again The problem of miscellaneous fluorine silica gel and mist block system.Absorbing liquid instead of the water in existing process for limewash in the present invention, carry High HS, HF absorptivity, with the addition of multiple baffle demister, wire gauzee filter and coke filter effectively eliminate mist and Blockage problem of some solid particles to whole system.Absorbing liquid is recycled in whole technical process, and saturated solution and heavy Starch is used in production calcium superphosphate, improves raw materials for production conversion ratio, discharge of the whole technique without waste liquid, waste residue and waste gas, Final gas discharge has reached discharging standards.
Specific embodiment:
During Waste Sulfuric Acid production calcium superphosphate the main component of tail gas for HS, HF, sulfide, smokeshade etc. it is complicated into Point, and the compositions such as mist, bubble and fluorine silica gel can be produced during vent gas treatment, and these compositions are in vent gas treatment process In easy block system, vent gas treatment efficiency is influenceed, because the present invention HS, HF, the sulfide that can remove in tail gas can be removed again Remove the compositions such as the mist generated in the flue gas particle in tail gas and processing procedure, bubble and fluorine silica gel simultaneously and eliminate tail gas In stink.
Processing method detailed process using tail gas during Waste Sulfuric Acid production calcium superphosphate is as follows:
