Technical field
The utility model relates to a kind of sulfur dioxide absorbing tower, especially absorbs the absorption tower of the sulfur dioxide that produces in the citric acid acidolysis process.
Background technology
Sulfur dioxide is modal oxysulfide, and colourless gas has the intense stimulus smell, is one of Air Pollutant Discharge.Acidolysis process in Citric Acid Production also has a certain amount of sulfur dioxide generation, for preventing environmental pollution, must in the acidolysis process, process acid hydrolysis tail gas, at present, although occurred the absorption plant of various sulfur dioxide on the market, to a certain extent can sulfur dioxide absorption, but the poor problem of ubiquity absorption efficiency.
Summary of the invention
For above problem, the utility model proposes a kind of sulfur dioxide absorbing tower, adopt the utility model can the Effective Raise removal rate of sulfur dioxide, improve the competitiveness of enterprise aspect environmental pollution improvement.
The utility model is mainly by the following technical solutions: a kind of sulfur dioxide absorbing tower, comprise tower body, and the tower body top is provided with gas vent, and the tower body inner bottom is provided with the medicament storage tank, and medicament storage tank top is provided with the gas access, and gas outlet is provided with air-introduced machine; The inner medicament storage tank of tower body top is provided with revolving top and packing layer from top to bottom successively, is provided with the medicament pipeline between revolving top and the medicament outlet, and revolving top and medicament pipeline are flexibly connected, and the medicament pipeline is provided with circulating pump.
At first, the tail gas that contains sulfur dioxide enters the absorption tower from the gas access of tower body bottom, because gas outlet is provided with air-introduced machine, can impel tail gas to move in tower body inside from bottom to top; Tail gas lower and on running in, medicament in the medicament storage tank rises to tower body top along the medicament pipeline under the effect of circulating pump, and spray from distributing device, be sprayed onto on the packing layer, tail gas fully contacted, mixes, reacted at the packing layer position with medicament this moment; The tail gas of removing after the sulfur dioxide continues to rise and discharge from the gas vent at tower body top, has absorbed the later medicament of sulfur dioxide and has continued descendingly, flow in the medicament storage tank of tower body bottom.Because distributing device is revolving top, and be flexibly connected with the medicament pipeline, guaranteed that medicament is more intensive, more be evenly distributed in the regional of packing layer, take full advantage of all attaching spaces of packing layer, increase the practical efficiency of filler.Compare with fixed distributing device, the part of adopting the distributing device of this structure effectively to reduce to cause because of nozzle blockage can not supplying medicament shortcoming, because even a certain nozzle blockage can't supplying medicament, in the rotary course of rotary material distributor, nozzle afterwards still can spray medicament cloth is carried out in this zone.
Further, the sealed at both ends and both sides of described revolving top trunk line vertically are provided with branch pipe(tube), and branch pipe(tube) is provided with the nozzle that rotation is arranged, and can guarantee that distributing device rotates uniform distribution under the effect of high-pressure injection medicament.
Filler in the packing layer is the stainless steel steel wire, and its diameter 1mm improves the surface area of filler device greatly, makes medicament and contains SO
2The tail gas contact area significantly improve, be SO
2Absorption advantage is provided.
In real work, each enterprise can adjust the filler degree of depth according to actual conditions, amasss and the time of tail gas by filler, SO in the more effective assurance tail gas to strengthen filling surface
2Removal.The medicament that adopts can be the alkaline solutions such as NaOH or potassium hydroxide.After medicament was repeatedly recycled, the workman can judge whether medicament lost efficacy by the concentration of active ingredient in the test agents, after medicament lost efficacy, the blowoff valve in its medicament exit was discharged.
In sum, the utility model adopts rotary material distributor and packing layer, and medicament carries out reverse haptoreaction with tail gas, has further increased contact area and the time of contact of tail gas and medicament, makes SO in the discharge tail gas
2Content effectively reduced, the clearance that has improved has solved SO in the present citric acid acidolysis process
2The problems such as medicament skewness, the gas-liquid contact time that absorption plant exists is short, desulfurized effect is poor improve the competitiveness of enterprise aspect environmental pollution improvement.
