The specific embodiment

Referring to figs. 1 through Fig. 5, a kind of wet type smoke abatement device, it comprises the smoke pipe 1 that is connected with exhaust opening 3, described smoke pipe 1 is tilted to setting for zig-zag type, smoke pipe 1 is connected with exhaust opening 3 by elbow 2, the elbow 2 outer high pressure positive blowers 4 that are provided with are as advancing, described smoke pipe 1 is provided with the wet type water injector, the wet type water injector is included in smoke pipe 1 outside high service person in charge 5 is housed, feed pipe is responsible on 5 and is provided with the mouth 51 that sprays water with high pressure that stretches in the smoke pipe 1 every suitable distance, be communicated with reflux tank 6 in the smoke pipe bottom near elbow 2 places, reflux tank 6 connects cold filtration device 8 by back water pump 7, and cold filtration device 8 delivery ports connect to supply water by supply-water pump 9 is responsible for 5.

Further improvement of the utility model, described cold filtration device 8 comprises cooling water tank 81, the coaming plate 82 of sealing around cooling water tank 81 is provided with, radiator fan 83 is equipped with on top in the coaming plate 82, driving air-flow during the radiator fan rotation down blows, there is return pipe nozzle 84 corresponding position, radiator fan 83 below, during work, the recirculated water of reflux tank 6 is transported to return pipe nozzle 84 through back water pump 7, atomizing ejection under high pressure cools back rapidly under the effect of radiator fan 83 and falls in the cooling water tank 81, for the aqueous vapor that makes atomizing is not easy to scatter and disappear from the top, having set up roof type loam cake 85 above coaming plate 82, is ventilating opening 86 between coaming plate and the roof type loam cake 85.

The utility model is provided with the mouth that sprays water with high pressure in the zig-zag type smoke pipe, utilize water spout to spray from the water atomization of feed pipe; Meanwhile, flue dust from exhaust opening 3 is advertised by the high-pressure blast of high pressure positive blower 4 after entering elbow 2, flue dust upwards flows at a high speed, when swiftly flowing flue dust runs into the water droplet of atomizing ejection from water spout 51, both produce impact and rub and fully mixing, harmful substance in the flue dust and dust particle etc. are mixed with water to flow in the reflux tank 6, the efficiency of dust collection height of the design's wet type smoke abatement device, can make the gas that is discharged into the external world reach environmental requirement, in addition, native system has reduced the temperature of smoke exhaust pipe owing to use recirculated water as adsorbing medium, goes for higher temperature and needs the working environment of operation continuously.

Smoke pipe described in the present embodiment 1 is the rectangle smoke pipe, and the manufacturing and the installation of rectangle smoke pipe are easier to, and the bottom surface is convenient to sewage and drains, and similarly also can use the smoke pipe of cross section for circular or other shape.

Further, the utility model is provided with water fender 11 in smoke pipe 1 inside outside corresponding to part water spout 51, because water fender 11 is arranged, the water that these water spouts 51 in water fender 11 fronts gush out when working can impact to splash on the water fender 11 and scatter, and water fender 11 back do not have water smoke, be formed for the pipeline that gas flows through, can reduce the resistance of smoke evacuation, reach dust removing effects again; Further, optimal way of the present utility model, described water fender 11 one of water spout installing of whenever being separated by.

In the such scheme, described water fender 11 is the radial setting of V-type, and the interior recess 12 of the radial water fender of V-type is corresponding to the axial line of water spout 51, when water when water spout gushes out, part can be flushed on the interior recess 12 of V-type of water fender, forms the regional up and down mixing that intersects, with abundant absorption flue dust.

Further; the utility model is provided with aqueous vapor separate mesh 13 on the top of smoke pipe 1; because the design's the main water of wet dust removal device is as the dedusting medium; often there are some moisture to be taken away from the smoke pipe top by gas; waste water resource; in addition; in order to strengthen dust removing effects and to make pipeline less scaling; usually can in water, throw in some Phytochemistry medicines; the aqueous vapor separate mesh is set, and can to make moisture content run into aqueous vapor separate mesh 13 back on the top of smoke pipe separated from the gas; gas water outlet place discharges, and moisture content is back to reflux tank 6 from smoke pipe.

For large enterprises such as coal-fired power plant, oil-refining chemical factories, often need equipment to run without interruption, therefore, at this class requirement of enterprise, the utility model designs standby or parallel system solves the problems referred to above, as Fig. 6, shown in Figure 7, adopt one main one auxilliary totally two groups of wet type water injectors, in addition, described cold filtration device 8 also can be installed in parallel by the multichannel unit, and its control mode also can be as required and flexible configuration.

The above be the utility model preferred embodiment, it does not constitute the restriction to the utility model protection domain, so long as realize that with essentially identical means the purpose of this utility model all should belong to protection domain of the present utility model.
