2the transformation efficiency of gas.At present, the primary structure on absorption tower comprises tubbiness tower body, and the inner and upper of tower body is provided with acid trap, acid trap connects the sour mouth of spray, in the below tower body of acid trap, be provided with the strut member with penetrating hole, on strut member, pile up and have filler, in the lower side of tower body, be provided with gas inlet and acid discharge mouth.As China Patent No. " 200520007382.7 " discloses a kind of sulfuric acid drying absorbing tower, its open day is on 04 26th, 2006, its technical scheme is that described absorption tower comprises tower body, at tower body internal upper part, be provided with acid trap, acid trap connects the sour mouth of spray, lower side at tower body is provided with gas inlet and acid discharge mouth, described tower body is the single layer structure of acidproof siliceous steel plate welding production, on the outer side of tower body, be fixed with stiffener, stiffener is uniformly distributed along the outer side of tower body, is provided with grate formula strut member in the below tower body of acid trap.
But the prior art that the above-mentioned patent document of take is representative, in actual use, still exist following defect: one, the sour mouth of a plurality of sprays in tower body, the acid solution that is often sprayed at central zone in tower body is more, and be sprayed near the acid solution of tower body inner wall area less, the homogeneity that acid solution is sprayed is poor, and this just makes the SO passing through from tower body central zone
2sO in gas
3gas is easily absorbed, and the SO passing through from tower body inner wall area
2sO in gas
3gas is not easy to be absorbed, and causes SO
2the low conversion rate of gas; Two, SO
2gas from the gas inlet of tower body enters in tower body, because filler and strut member stop, SO
2gas is slower to the speed of tower body top motion, not only causes SO
2the low conversion rate of gas, also causes SO
2the transformation efficiency of gas is low.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, provides in a kind of pyrite-based sulfuric acid production technique and improves SO
2the absorption tower of transformation efficiency, the utility model can be accelerated SO in tower body
2the velocity of flow of gas, is accelerating acid solution and SO
3in the time of gas reaction speed, improve SO
2the transformation efficiency of gas.
For achieving the above object, the technical solution adopted in the utility model is as follows:
In a kind of pyrite-based sulfuric acid production technique, improve SO
2the absorption tower of transformation efficiency, it is characterized in that: comprise tower body and suction fan, this tower body is provided with acid discharge mouth, inlet mouth, packing support part, acid separating device, acid inlet and air outlet from bottom to up successively, described acid separating device is connected with acid inlet, between described packing support part and acid separating device, filler is housed, described suction fan is fixedly mounted on the tower body outer wall between packing support part and acid separating device, the air suction inlet of described suction fan is communicated with air outlet, and the air outlet of described suction fan is communicated with vapor pipe.
Described acid separating device comprises the sour mouth of a plurality of sprays and the sour house steward of the confession being connected with acid inlet, and the sour house steward of described confession is helicoidal structure, and the sour mouth of described a plurality of sprays is evenly fixed on the sour house steward of confession of helicoidal structure.
The quantity of the sour mouth of the upper spray of the sour house steward of described confession is 30-38, and each spray angle that sprays sour mouth is less than 60 degree.
Employing the utility model has the advantage of:
One,, in the utility model, by suction fan, can accelerate SO in tower body
2the gas mobile speed that makes progress, is conducive to improve acid solution and SO
2sO in gas
3the speed of response of gas; In addition, suction fan can produce certain vibration when work, therefore, is arranged on the suction fan on the tower body outer wall between packing support part and acid separating device, and the vibration of generation can be accelerated the downward velocity of flow of acid solution in tower body, is conducive to improve SO
2the transformation efficiency of gas and production efficiency.
Two, in the utility model, described acid separating device comprises the sour mouth of a plurality of sprays and the sour house steward of the confession being connected with acid inlet, the sour house steward of described confession is helicoidal structure, the sour mouth of described a plurality of spray is evenly fixed on the sour house steward of confession of helicoidal structure, this structure makes to spray the acid solution that sour mouth sprays can cover tower body inside equably, is conducive to improve SO
3the assimilation effect of gas.
Three, in the utility model, the quantity of the sour mouth of the upper spray of the sour house steward of described confession is 30-38, and each spray angle that sprays sour mouth is less than 60 degree, and this structure guarantees that the spray effect of acid solution is better, further improves SO
