The acid mist treatment system
Technical field
The utility model relates to a kind of treatment system, especially a kind of acid mist treatment system.
Background technology
The processing of acid mist at present, it is the most suitable from the angle of reducing investment outlay, to select for use " wet method " technology to remove acid mist.The mode of wet processing has quite a few kinds, and like traditional eddy flow moisture film pinnacle, and eddy flow adds tubulent contact tower etc.But the poor processing effect of these two kinds of treatment systems, operating cost are high, and the external structure of the big tower of moisture film is looser, the crack occurs easily and leak, leak gas, and therefore are not durable.
The utility model content
The purpose of the utility model provides that a kind of treatment effect is good, cost is low, the acid mist treatment system of long service life.
Realize the acid mist treatment system of the utility model purpose, comprise the air-suction cover, pretreatment chamber, purifying column, air-introduced machine and the delivery pipe that link to each other successively, the wastewater outlet of said pretreatment chamber and purifying column links to each other with sewage plant; Said purifying column is a fountain vacuum filler filtration tank.Fountain vacuum filler filtration tank, treatment effect is good because resistance is little, getting rid of needs air-introduced machine power less relatively, thereby so power saving reduced operating cost, more durable.
Said fountain vacuum filler filtration tank comprises tower body, from bottom to top is provided with one-level packing layer, secondary packing layer and demister in the tower body successively.
The beneficial effect of the acid mist treatment system of the utility model is following:
1, the acid mist treatment system of the utility model, floor space is few.
2, investment is lower, and operating cost is low.
3, the clearance of acid mist is high, and clearance reaches more than 85%.
4, easy maintenance, simple to operate, personnel can accomplish overall device operation.Entire equipment is of a tightly knit structure, and durable, long service life.
Description of drawings
Fig. 1 is the structural representation of the acid mist treatment system of the utility model.
The specific embodiment
The embodiment of the utility model is following:
As shown in Figure 1, the acid mist treatment system of the utility model comprises the air-suction cover, pretreatment chamber, purifying column, air-introduced machine and the delivery pipe that link to each other successively, and the wastewater outlet of said pretreatment chamber and purifying column links to each other with sewage plant; Said purifying column is a fountain vacuum filler filtration tank.Fountain vacuum filler filtration tank, treatment effect is good because resistance is little, getting rid of needs air-introduced machine power less relatively, thereby so power saving reduced operating cost, more durable.
Said fountain vacuum filler filtration tank comprises tower body, from bottom to top is provided with one-level packing layer, secondary packing layer and demister in the tower body successively.
The operation principle of the acid mist treatment system of the utility model is following: acid mist uses cleanser to carry out preliminary treatment through air-suction cover inspiration pretreatment chamber; Sending into purifying column then further handles; Discharge through air-introduced machine and delivery pipe at last, the sewage of pretreatment chamber and purifying column purifies the back discharging through sewage plant.
In purifying column; Flue gas at first gets into the packing layer of tower body below; Work through the one-level filler makes water contact with gas, earlier remove partly dust and solubility waste gas about 20%, when the gas that continues to rise gets into tower body; Contain alkalies and under the effect of secondary filler, fully contact with waste gas once more, make the waste gas clearance in the waste gas reach 40-50%.When gas rose to the demister district, demister dammed back the moisture in the flue gas in the tower, thereby avoided the moisture outflow and the corrosion chimney.Mainly in this segment process, dust removal efficiency reaches more than 90% each pollutant, and acid mist waste gas clearance reaches 85%.But flue gas qualified discharge after treatment.
The advantage of the acid mist treatment system of the utility model is following:
1, the acid mist treatment system of the utility model, floor space is few.
2, investment is lower, and operating cost is low.
3, the clearance of acid mist is high, and clearance reaches more than 85%.
4, easy maintenance, simple to operate, personnel can accomplish overall device operation.Entire equipment is of a tightly knit structure, and durable, long service life.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in this area make the utility model technical scheme all should fall in the protection domain that claims of the utility model confirm.
