The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing
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 enrichment facility 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, and described purified solution storage pool 33 is connected with collecting pit 5 through waste water enrichment facility 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 is formed, 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, liquid under described shower nozzle 223 sprays evenly is covered with the cross section of whirlwind spray cleaning device 2, and 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 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 is produced, and useless flue gas draws, assembles the back in and sends into whirlwind spray cleaning device by pipeline.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 action of centrifugal force, sink down into dust storage chamber by deadweight, 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 the 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, the fine solid particle weightening finish sedimentation of atomizing back, 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 sediment sinks at the bottom of the pond, and the aqueous solution covers and separates coping and enter the purified solution storage pool, finish dirt, moisture from.Purified solution in the purified solution storage pool extracts to the waste water enrichment facility through water pump and concentrates, and discharges from outlet to flow into the collecting pit, can change other (as gypsum) industries after the centralized collection over to, recycles as industrial chemicals.
The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, all falls within protection scope of the present invention.
The technology that the present invention does not describe in detail, shape, structure partly are known technology.
