The specific embodiment:

The present invention is further illustrated below in conjunction with accompanying drawing, see shown in Fig. 1~3, industrial waste gas purification device, it includes casing 1, water injector 9, gas filtration processing layer 12, gas filtration processing layer 12 is an activated carbon filter layer, also available similar substance with identical function replaces active carbon, be used for eliminating the various harmful chemicals of gas, offer bleeding point 4 and gas discharge outlet 13 on the casing 1, the top of casing 1 is provided with seal cover 10, water injector 9 is located at the top of casing 1 inner chamber, be provided with circuitous chamber 5 of the gas that is positioned at water injector 9 belows and the gas dispersion chamber 11 that is positioned at gas discharge outlet 13 places in casing 1 inner chamber, gas filtration processing layer 12 is arranged between gas dispersion chamber 11 and the gas discharge outlet 13, and bleeding point 4 is communicated with the bottom in the circuitous chamber 5 of gas, and gas dispersion chamber 11 is communicated with the top in the circuitous chamber 5 of gas.Gas is provided with multilayer choke net 6 in the circuitous chamber 5, and choke net 6 is horizontal positioned, and a side of choke net 6 offered gas port 16, and three limits of choke net 6 except that crossing gas port 16 all contact with the circuitous chamber of gas 5 inwalls, and the gas port 16 of crossing of adjacent two layers choke net 6 staggers mutually.Choke net 6 can allow water and waste gas pass, simultaneously also can allow dust pass mesh drops in the tank 2, wherein coarse powder dust particle drops on the highdensity screen pack 3, quantity can be opened cleaning door 15 for a long time and be cleared up, but covered owing to spill the water that gets off above the choke net 6, waste gas is difficult to pass choke net 6, most waste gas can only be passed through by the circuitous space between the choke net 6, space between the multilayer choke net 6 forms circuitous gas circuit, gas circuit is complicated, increase the gas circuit route, when increasing waste gas and the time of contact of water through the circuitous chamber 5 of gas, viscosity lacquer slag in the waste gas, dust such as non-volatile matter is with after the water of water injector 9 ejections mixes, drop on the highdensity screen pack 3, make to keep no coarse shot-like particle in the water of tank 2, do not influence the water pump normal operation, dietary fibres on the screen pack 3 can be cleared up according to its degree of congestion, and dust purification is effective; Waste gas enters the circuitous chamber 5 of gas from bleeding point 4 earlier and carries out dust purification, the dustless waste gas that utilizes gas filtration processing layer 12 to discharge again continues the charing filtration treatment, like this, can be not by dust barrier gas filtration treatment layer 12, make it possible to eliminate long-term effectively the various harmful chemicals in the gas, waste gas is discharged from gas discharge outlet 13 after filtering, and good purification can guarantee enterprise's operate as normal.

Side at casing 1 is provided with water pump 7, and the below in the circuitous chamber 5 of gas is provided with tank 2, and the input port of water pump 7 is communicated with tank 2, and its delivery outlet is communicated with water injector 9 by aqueduct 8, is provided with high density filter net 3 between circuitous chamber 5 of gas and the tank 2.The present invention with coarse dust collection to highdensity screen pack 3, amount is cleared up for a long time, the dustless waste gas of discharging is continued filtration treatment through gas filtration processing layer 12, the viscosity that the highdensity screen pack 3 in place can not stop is coated with lacquer slag, dust such as non-volatile matter dissolve in the water of tank 2, after the work long period, the micronic dust shot-like particle increases when a certain amount of gradually, can influence water pump 7 work, at this moment addle is entered in the tank 2 of other preparation, take turns water storage through the tank of several preparations and make non-volatile material precipitation, utilize other water pump of preparation in the water suction tank 2 of post precipitation, to reuse again, not contaminated air.

Wherein, water injector 9 includes the many rows sparge pipe 17 that is interconnected, evenly be provided with a plurality of shower nozzle 18 or the tanks of water spray down on every row's sparge pipe 17, the shower nozzle 18 or the tank of this water injector 9 are evenly distributed, water spray is even and area is wide, effectively increase the contact area of waste gas and water, make the dust in the waste gas soluble in water more fully.Certainly, water injector 9 also can be the constructional device of other large tracts of land water spray.

In addition, the outside of gas discharge outlet 13 is provided with the side door 14 that can open and close, and is convenient to repair gas filtration processing layer 12.A side of casing 1 also is provided with the cleaning door 15 that can open and close, convenient operation to casing 1 inside.

In sum, the present invention not only clean-up effect is remarkable, and the conserve water resource, and is free from environmental pollution.

See Fig. 4, another embodiment as invention, different from the embodiment described above is, between adjacent two layers choke net 6, also all be provided with horizontal shower nozzle 19, horizontal shower nozzle 19 lays respectively on two inboards in the circuitous chamber 5 of gas, horizontal shower nozzle 19 is partly tubaeform, its top, horizontal, the bottom is downward-sloping, makes the current level spray or downward-sloping ejection, and can upwards not spray, the water spraying direction of horizontal shower nozzle 19 is opposite with airflow direction between the two-layer choke net 6 that it is positioned, flow from water and air-flow collision that horizontal shower nozzle 19 gushes out, the dirt that more increases gas makes it to quicken to mix with the fierceness friction of water, produces better clean-up effect.

See Fig. 5, another embodiment as invention, removing casing 1 with above-mentioned embodiment enlarges equally, make outside the gas slowly rising, different is, gas does not have choke net 6 or only is provided with one deck choke net 6 in the circuitous chamber 5, and the circuitous gas circuit of the industrial waste gas purification device of this structure is uncomplicated, the rate of filtration is very fast, is applicable to that purification does not contain the waste gas of oil paint slag.

See Fig. 6, as the another embodiment of invention, different is that its casing 1 inside has only one deck can filter the current-sharing choke net 20 of coarse slag, circuitous chamber of gas and choke net are not established in the inside, the effect of current-sharing choke net 20 be stop gas straight on, upwards flow equably after making gas dispersion, because casing has enlarged, air-flow is slack-off, water under top water injector 9 sprays is direct and gas is crosslinked, dust is met fall under water, and this structure also is to be applicable to that purification does not contain the waste gas of oil paint slag.In addition, be provided with dust proof 21 at the top of casing 1, the top of dust proof 21 is provided with rain shield 22, prevents that external environment condition from falling into the dust obstruction current-sharing choke net 20 of thick shape.

Certainly, the above only is a better embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
