Description
Technical field
The utility model relates to smoke eliminator, relates in particular to a kind of wet fume purifier.
Background technology
The gas wet cleaning is that dusty gas is contacted with water or other liquid, and the grit in the gas is subjected to the interception of liquid or is got off by liquid trap because of inertia and water droplet or moisture film collision, and gas is purified.The device category of wet cleaning is more, and common having is following several: 1. 2. cyclone scrubber of spray jet scrubber.This wherein comprises cyclonic water film deduster and cylinder-rotating deduster again, and three types of the cyclone scrubbers of center spraying.3. 4. 5. 6. Venturi scrubber of turbulent flow tower washer of foam scrubber of auto-excitation type spray jet scrubber.Except that above-mentioned six big classes, also have packed bed formula washer and mechanical induction spray jet scrubber etc.
Above-mentioned technique device is mostly bulky, makes complicatedly, invest greatlyyer, and water consumption is big, is not suitable for the smoke abatement use of the small incinerator of township enterprise.
At present individuality is torn old rent workshop emerge in multitude open in the township enterprise, wherein some local quite a few be engaged in scrap electrical wires and lead mould peeling off of skin and copper core.And thin wire stripping is very hard very difficult, thereby takes the burning way to reclaim wherein copper.Plastic plastic skin is burned, thereby emits a large amount of waste gas that contains flue dust, is seriously polluting the air in rural area, is greatly damaging the healthy of peasant.
From the waste or used plastics electric wire, reclaim metallic copper, generally use physical method, cut fragmentations such as mill, processes such as elutriation.Equipment is huge, and investment is big, and one of import needs about 1,000,000 yuan of RMB.The old cable in plastics of tearing open in rural area reclaims copper now, and thick line is peeled off with hand, and fine rule adopts the way of burning.Plastic foreskin is burnt, reclaimed the copper core.The plastics copper cash is after burning, and waste gas freely discharges, and strengthens contaminated air and environment.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1,
The trend of expression flue gas.A kind of wet fume purifier of the utility model, comprise that the waste gas that is used for containing flue dust pumps to the blower fan 1 of this purifier, the air outlet of described blower fan 1, reducing pipe 2, trunnion 4, increaser 5 are communicated with from top to bottom successively, this purifier also is provided with liquid circulating apparatus and water tank 9 and the coupled logical secondary spraying tube 11 that is positioned at its top, the inner chamber top of described secondary spraying tube 11 is provided with demister 14, and the top is provided with purified gas outlet 15; The lower end of described increaser 5 places in the liquid of water tank 9; The degree of depth of inserting is advisable with 50～100mm.Described liquid circulating apparatus comprises the overfall that is arranged on water tank 9 sidewalls, and overfall and overflow pipe 6 join, and described overflow pipe 6 is communicated with the effluent settling chamber 7 that is provided with delivery port 7-1; Liquid circulating apparatus comprises that also the circulating pump 8 that is communicated with water tank 9, the water pipe 10 that is communicated with circulating pump 8, the inner chamber top that is arranged at secondary spraying tube 11 that is communicated with water pipe 10 are positioned at nozzle II12, the nozzle I3 that is arranged at reducing pipe 2 that is communicated with water pipe 10 below the demister 14, and water pipe is provided with water inlet 13.
Can buy on the air exhauster market, existing small blast fan can use; Pipeline and valve also can have been bought finished product from market; Tubular structure can be made entire combination assembling then with general carbon sheet welding by design size.Nozzle I, the II of atomizing usefulness makes by the design machined; Purification is adopted usually in the water with liquid and is added surfactant and can be recycled, and catches recirculated water in the irregular replacing water tank of muddy degree behind the flue dust according to water, to reach using water wisely.Sewage is discharged to effluent settling chamber and discharges after sedimentation, can reach environmental protection requirement fully.
Operation principle of the present utility model:
Air exhauster pumps to cleaning system with flue gas; Water pipe and nozzle I and nozzle II, the liquid that is used to be used in purification reaches the atomizing shape.This decontaminating liquid adds surfactant, so that wetting better soot dust granule surface, reaches by liquid and coats.Usually this decontaminating liquid adopts common well water or running water, not only cheaply but also convenient.The dust and the water smoke that enter purifier form superfine extremely many droplets through the stirring that reducing pipe, trunnion produce fierceness, the little droplet that has surfactant is wetting with soot dust granule, condense into the larger particles that water dust mixes, through behind the increaser, flow velocity reduces, make the effect of cohesion carry out sooner, flue gas includes the impact type washing of surfactant solution again through water tank, enter the secondary spraying tube through the atomized liquid spraying and dedusting, carry out aqueous vapor by demister and separate, purified gas is discharged this purifier.Ash-laden gas at first after the efficient spray washing dedusting of the Venturi scrubbing pipe through comprising reducing pipe, trunnion, increaser, enters the cleaning dust once more of carrying out impact type in the solution in the water tank, enters the secondary spraying tube at last and carries out spray washing dedusting once more.By the structure of Venturi tube, the coupling of impact type water tower deduster, remedy the deficiency of single udst separation, mixing of cigarette G﹠W and spray are hit, thereby improve purification efficiency; The purification water recycles, environment protection emission; The demand that adapts to current rural area waste plastics incineration flue gas, the efficient height, volume is little, and cost is low, water-saving, smoke abatement efficient can significantly reduce the pollution of flue dust 85%～95% by experiment.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make a lot of forms, these all belong within the protection domain of the present utility model.
