Described moisture film purification plate is multiaperture-type or screen mesh type double-decker.
The utlity model has following beneficial effect: the utility model is rationally distributed, adopts the dedusting of whirlwind spray cleaning device, and to the fine solid particle good dedusting effect, the solution after purification is recycled after concentrated, economize on resources, and is beneficial to environmental protection.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1, aggregation cover, 2, whirlwind spray cleaning device, 3, the dirt water separation tank, 4, Waste water concentrating device, 5, collecting pit, 21, ,22, spray dust district, cyclone dust collection district, 23, exhaust outlet, 24, scavenge port, 211, bucker, 212, smoke dust duct, 213, dust storage chamber, 214, dust-exhausting port, 221, spray equipment, 222, moisture film purification plate, 223, shower nozzle, 31, sedimentation basin, 32, separate wall, 33, the purified solution storage pool, 34, water pump.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated
as shown in Figure 1, a kind of crucible type Metal Melting emission-control equipment, comprise aggregation cover 1, whirlwind spray cleaning device 2, dirt water separation tank 3, Waste water concentrating device 4, collecting pit 5, described aggregation cover 1 is connected with whirlwind spray cleaning device 2, described dirt water separation tank 3 is divided into sedimentation basin 31 and purified solution storage pool 33 by separating wall 32, described whirlwind spray cleaning device 2 is connected with the top of sedimentation basin 31 by scavenge port 24, the height of described separation wall 32 is lower than the position of scavenge port 24, described purified solution storage pool 33 is connected with collecting pit 5 through Waste water concentrating device 4 by water pump 34,
described whirlwind spray cleaning device 2 is by cyclone dust collection district 21, spray dust district 22, the scavenge port 24 of the exhaust outlet 23 at top and 22 bottoms, spray dust district forms, described cyclone dust collection district 21 comprises smoke dust duct 212, the dust storage chamber 213 of smoke dust duct 212 belows and the bucker 211 that is positioned at smoke dust duct 212 tops, described dust storage chamber 213 bottoms are provided with dust-exhausting port 214, described spray dust district 22 comprises the spray equipment 221 that is positioned at exhaust outlet 23 belows, described spray equipment 221 is provided with a plurality of shower nozzles 223, uniform liquid under described shower nozzle 223 sprays is covered with the cross section of whirlwind spray cleaning device 2, described spray equipment 221 belows are provided with moisture film purification plate 222,
Described moisture film purification plate 222 is multiaperture-type or screen mesh type double-decker.
In the Metal Melting process, fire door can discharge a large amount of ash-laden gas, aggregation cover is set and exactly these useless flue gases is drawn in, assemble, the size of aggregation cover, the depth depend on the size of the fume amount that produces, and useless flue gas is sent into whirlwind spray cleaning device by pipeline after drawing in, assembling.When flue dust enters the cyclone dust collection district of whirlwind spray cleaning device, the flue dust air-flow is along certain direction high-speed and continuous rotation, big dust particle collides the wall that gathers dust under the effect of centrifugal force, by deadweight, sink down into dust storage chamber, subsequently regularly or quantitatively dust is removed from scavenge port.Uncollected fine solid particle enters in the spray dust district from smoke dust duct with flue gas, shower nozzle on spray equipment, spray top-down fog-like liquid, and the flue gas that contains fine solid particle from bottom to top crosses between the moisture film purification plate, fine solid particle weightening finish sedimentation after atomization, acidic flue gas and the neutral degraded of alkaline water smoke flow into the dirt water separation tank in the lump, the purpose that double-deck moisture film purification plate is set is to increase crossing time of contact of fine solid particle flue gas and vaporific alkaline water, to improve absorption and neutralization.Dust-laden liquid precipitates after flowing into sedimentation basin, and at the bottom of sediment sank to pond, the aqueous solution covered and separates coping and enter the purified solution storage pool, complete dirt, moisture from.Purified solution in the purified solution storage pool extracts to the Waste water concentrating device and concentrates through water pump, from outlet, discharges and flows into collecting pit, after centralized collection, can change other (as gypsum) industries over to, as industrial chemicals, recycles.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
