Abstract
The utility model relates to a waste gas purifying device, in particular to equipment for dust extraction, dehydration and desulphurization of industrial waste gas; the technical proposal is that: the waste gas purifying device comprises a waste gas inlet (5), a spraying device, a sewage box (4), a spiral shaped channel and a flue gas outlet; the waste gas inlet, the spraying device and the sewage box (4) are sequentially arranged, the spiral shaped channel is arranged above the sewage box, and the flue gas outlet is arranged at the top end of the spiral shaped channel; the waste gas purifying device has the beneficial effects that: compared with the common equipment for dust extraction, dehydration and desulphurization of industrial waste gas, the investment is saved by two thirds; the device has low resistance and high efficiency, the water collecting efficiency of the spiral shaped channel can each 90 percent without secondary pollution; the structure is simple and can replace common wet-type dust removal facilities such as an impact wet-type filter collector, a water bath dust catcher and the like; the waste gas which achieves the encoding standard can be discharged to air after secondary purification is carried out, thereby having the functions of environment protection and waste water circulation and pollution reduction.
Description
Affiliated technical field:
The utility model relates to a kind of purifier of waste gas, the equipment of particularly industrial waste gas dedusting, dehydration, desulfurization.
Background technology:
At present, coal slime, brown coal drying and upgrading can produce large quantity of exhaust gas, industries such as metallurgy, building materials also produce a large amount of hot industry waste gas, need carry out purified treatment, and the method for industrial waste gas dedusting, dehydration, desulfurization mainly comprises following process: industrial waste gas is fed in the water, carry out water bath dust-removing, perhaps, mix, separate and carry out udst separation or the like, desulfurization if desired by air water to the waste gas shower water, in water, add alkaline matter, and undertaken by desulfurizer.The problem that above-mentioned method for purifying waste gases and equipment exist is: investment is big, technology and complex structure, and purification efficiency is low.
The utility model content:
The utility model purpose provides a kind of purifier of waste gas, and simplified structure reduces investment, improves purification efficiency, and energy-conserving and environment-protective solve the problems referred to above that background technology exists.
The utility model purpose is achieved through the following technical solutions:
The purifier of waste gas comprises exhaust gas entrance, spray equipment, foul water tank, helical channel, exhanst gas outlet, and exhaust gas entrance, spray equipment, foul water tank arrange that successively the top of foul water tank is provided with helical channel, and the top of helical channel is provided with exhanst gas outlet.
The quantity of said helical channel can be one, also can be more than two, and the center of helical channel can be hollow, when flue gas passes through, forms a gas column.Helical channel is exactly the cavity that is made of helical blade, helical form is spiraled and advanced, and also is provided with water fender on helical blade, makes that the sewage under the collection drips, and secondary is blown afloat and takes away by air-flow never again.
Exhaust gas entrance is a downward elbow, makes the direction of exhaust-gas flow downward before this, and spray equipment comprises spraying water nozzle and sparge pipe, is arranged on the exhaust gas entrance place, and foul water tank is arranged on the exhaust gas entrance bottom, and the bottom of foul water tank is provided with sewage draining exit and flashback tank.
When putting into suitable basic species in the spray water, this system also plays desulfidation.
Containing micronic dust waste gas is squeezed in the malleation mode by air-introduced machine, mix with shower water, the dust that carries in the waste gas is dissolved in the water droplet, because the effect of malleation, the direction of waste gas was downward before this, racing makes progress for 180 ° again then, and the sewage that major part is contained dust throws away by centrifugal action, and sewage can enter sewage disposal system and recycle.
Waste gas after first time dedusting dehydration purifies enters the helical channel dehydration immediately and purifies, and is in contact with one another at spiral and waste gas and not only slows down flow velocity in the collision, and the water droplet with contained micronic dust collects again, flows down by the suitable spiral wall of its gravity, repeats above-mentioned circulation.
The utility model is not only applicable to coal drying and dewatering, but also can be widely used in metallurgy, building materials and other waste gas purification places.
The beneficial effects of the utility model are: compare with common industrial waste gas dedusting, dehydration, desulphurization plant, reduce investment outlay 2/3rds; The little purification efficiency height of resistance, the water collection efficiency of helical duct can reach 90 percent, can not produce secondary pollution; Simple for structurely can replace wet dust removal facilities such as common impact wet filter dust collecting technique device, wet dust collector; Waste gas behind the double purification is disposed to atmosphere after reaching " GB ", has played the i.e. reduction of discharging effect that circulates of environmental-protection function and waste water.
