Abstract
The utility model discloses a waste gas treatment system. The system comprises a gas-collecting hood, a fan, an absorption purification tower, a circulating dosing pond and a desulfurization circulating pump, wherein the gas-collecting hood, the fan and the absorption purification tower are connected sequentially from front to back; the waste water outlet of the absorption purification tower is connected with the circulating dosing pond; the output end of the circulating dosing pond is connected with the input end of the desulfurization circulating pump; and the output end of the desulfurization circulating pump is connected with the absorption purification tower. Acid mist waste gas is treated by the treatment system and can be emitted after reaching the standard; the treatment system adopts a treatment process with good purification effect, stable performance, low energy consumption, low running cost, small floor area and convenience in maintenance and operation; the service life of the equipment is long, only the purification tower is in a vapor-liquid two-phase contact state in the whole system, and the purification tower is made of an acid/alkali-resistance and corrosion-resistance material.
Description
[technical field]
The utility model relates to the technical field of exhaust-gas treatment, particularly the technical field of acid mist exhaust treatment system.
[background technology]
Country's being widely used alloy product at present.Its drawback is that aluminium alloy can produce a large amount of acid mists in process of production, serious to the infringement of plant and equipment, severe contamination air, and the health of the personnel to periphery has great harm.
The processing of acid mist at present, from the angle of reducing investment outlay, if the treatment systems such as traditional eddy flow moisture film pinnacle are suitable, but this system poor processing effect, operating cost is high, is not durable.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of exhaust treatment system, and treatment effect is good, and cost is low, and the life-span is long.
For achieving the above object, the utility model proposes a kind of exhaust treatment system, comprise gas skirt, blower fan, type absorption purification tower, circulation dosing pond and desulfuration recycle pump, described gas skirt, blower fan and type absorption purification tower are connected from front to back successively, the wastewater outlet of described type absorption purification tower connects circulation dosing pond, the output in described circulation dosing pond connects the input of desulfuration recycle pump, and described desulphurization circulating delivery side of pump connects type absorption purification tower.
As preferably, described blower fan is rotproofness centrifugal fan.
As preferably, the multistage absorption tower that described type absorption purification tower is support holder structure.
As preferably, the multistage absorption tower of described support holder structure comprises tower body, in described tower body, is provided with packing layer, and in described packing layer, filler is the hollow ball of 38 millimeters of diameters, and the top of described tower body is also provided with demister.
As preferably, described desulfuration recycle pump is rotproofness circulating pump.
The beneficial effects of the utility model: the utility model is by treatment system by qualified discharge after acid mist exhaust-gas treatment, and this treatment system adopts good purification, stable performance, low energy consumption, low operating cost, floor space treatment process few, easy to maintenance and easy and simple to handle; Equipment life is long, and only purifying column is in gas-liquid two-phase contact condition for whole system, and purifying column adopts acid and alkali-resistance, anti-corrosion material to make.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is that the structure of the utility model exhaust treatment system is looked schematic diagram.
In figure: 1 gas skirt, 2 blower fans, 3 type absorption purification towers, 4 circulation dosing ponds, 5 desulfuration recycle pumps.
[specific embodiment]
Consult Fig. 1, the utility model comprises gas skirt 1, blower fan 2, type absorption purification tower 3, circulation dosing pond 4 and desulfuration recycle pump 5, described gas skirt 1, blower fan 2 is connected from front to back successively with type absorption purification tower 3, the wastewater outlet of described type absorption purification tower 3 connects circulation dosing pond 4, the output in described circulation dosing pond 4 connects the input of desulfuration recycle pump 5, the output of described desulfuration recycle pump 5 connects type absorption purification tower 3, described blower fan 2 is rotproofness centrifugal fan, the multistage large-scale absorption tower that described type absorption purification tower 3 is support holder structure, the multistage large-scale absorption tower of described support holder structure comprises tower body, in described tower body, be provided with packing layer, in described packing layer, filler is the hollow ball of 38 millimeters of diameters, described tower body top is also provided with demister, described desulfuration recycle pump 5 is rotproofness circulating pump.
The utility model course of work: in the course of the work, waste gas, after gas skirt 1 is drawn by blower fan 2, first enters acid mist waste gas absorption purifying column 3 to a kind of exhaust treatment system of the utility model.Type absorption purification tower 3 neutral and alkali cleaning solutions are evacuated in tower by circulating pump, flow downward through filler, acid mist waste gas adverse current rises, at the wetted surface gas-liquid contact of filler, there is a series of physical-chemical reaction, and because mass transport process occurs concentration difference, thereby complete by gas cleaning process direct qualified discharge after the waste gas dehydration after purification.In the time that alkaline detergent solution pH value reaches certain value, need regular dosing to change the circulation fluid in circulation dosing pond 4; Circulation fluid saturated in circulation dosing pond 4 is regularly disposed to Sewage Disposal processing, to guarantee the normal working concentration of circulating medical solution.The utility model is by treatment system by qualified discharge after acid mist exhaust-gas treatment, and this treatment system adopts good purification, stable performance, low energy consumption, low operating cost, floor space treatment process few, easy to maintenance and easy and simple to handle; Equipment life is long, and only purifying column is in gas-liquid two-phase contact condition for whole system, and purifying column adopts acid and alkali-resistance, anti-corrosion material to make.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
