Abstract

Disclosed is a three-level highly effective dust-removing and purification device, which is the combination of Veturi and the active carbon filter for an incinerator. The utility model comprises a multilevel dust-removing device, a flue, an induced fan and a chimney. The device is characterized in that the multilevel dust-removing device is combined by a cyclone dust collector for first-level processing, a Veturi water-bath dust collector for second-level processing and an (fiber) active carbon purifier for absorbing and removing dioxin at the third level, which are sequentially installed. In contrast with the prior art, the utility model has the advantage of effective dust removing (even desulphurizing) and discharging dioxin up to the standard for a complete tail gas purifier due to the three-level combination of the efficient dust-removing purifier. The device is simple in structure, easy for installation and highly effective in purification, which is applicable to purifying the smoke from the garbage incinerator and the dusty gas in metallurgical, mining, coal and founding industry.

Description

The three-stage high-effective dust-removing cleaning equipment of venturi and active carbon filter combination

Technical field: the utility model belongs to the smoke abatement and dust control purifier of environmental protection equipment, particularly a kind of three-stage high-effective dust-removing cleaning equipment that is mainly made up by venturi (pipe) deduster and active carbon filter.

Background technology: environmental protection is a fundamental state policy of China, at present to various incinerators (as incinerator) the udst separation of generation volume of smoke and other pernicious gases (as dioxin organic carcinogen, sulfur dioxide etc.) be subjected to the extensive attention of governments at all levels and general public day by day.Though many comparatively effectively smoke dispersal, dust removal and desulphurization purifiers (these cleaners have wet type or dry type) are arranged at present, if any the cyclone dust removal formula, venturi (pipe) deduster, impingement washing scrubber and fiber bag precipitator or the like.When these dedusters are used singly or in combination, because of structural reason or combined method mode are oversimplified and when scientific and reasonable inadequately (just single-stage or secondary simple combination), the udst separation effect that it is actual is particularly in the shortcoming (there is very strict restriction in country to the dioxin qualified discharge) that also has the severe overweight discharging aspect the removing dioxin organic carcinogen.For example existing hollow drum type cyclone dust collector only is applicable to the removing of big dust particle, and the small particles flue dust is removed poor effect, though and venturi scrubber is a kind of high-effective dust-removing device, the adsorption removal dioxin is seemed powerless.

The purpose of this utility model is the deficiency that will overcome above-mentioned prior art, thereby design a kind of three-stage high-effective dust-removing cleaning equipment that mainly comprises venturi and active carbon filter combination, it have simple in structure, cost is low, installation is controlled conveniently, dust can be eliminated, the effect of dioxin emission compliance can be made again.

The utility model is realized with following technical scheme, it comprises multistage dust arrester, cross flue, composition such as air-introduced machine, chimney, it is characterized in that described multistage dust arrester be meant be docile and obedient that preface lay to install as the first order handle the cyclone dust collectors of (removing crude particle dust), as handling venturi (pipe) wet dust collector of (adsorption removal particle dust and desulfurization) and combine in the second level as the active carbon purifying device (filter) that the third level is used for the adsorption removal dioxin.

Compared with the prior art, the utility model is owing to adopt the high-effective dust-removing cleaning equipment of three grades of reasonable combination, can efficiently eliminate dust (even desulfurization), can make the dioxin qualified discharge again, thereby form a comparatively perfect exhaust gas cleaner, complete machine structure is simple, easy for installation, the purification efficiency height is specially adapted to the gas cleaning of incinerator, also applicable to the purification of industry ash-laden gas such as metallurgy, mine, coal, casting.

Description of drawings: Fig. 1 is a kind of overall structure schematic diagram of the present utility model.

Wherein: 1-incinerator, 2-incinerator secondary combustion chamber, 3-cyclone dust collectors (being prior art), 4-crosses flue, 5-venturi (pipe) wet dust collector (can play heat exchange action, be prior art), the 6-water pump, 7-clear water reserviors, 8-air-introduced machine, the 9-third level removable (bar gate type) active carbon purifying device (filter), 10-glass outer fiber filtering layer, the composite fibre active carbon filtering layer of 11-intermediate course, the 12-chimney, the 13-nozzle, 14-sedimentation basin, 15-dewatering station.

The specific embodiment: as can be known with reference to accompanying drawing, the utility model also can have following technical characterictics when specific design is implemented: the active carbon purifying device of described third level adsorption removal dioxin can be to be made of the filtering layer that the multilayer composite fiber active carbon of movable dismounting is made, or constitute (accompanying drawing is slightly) by the composite fibre active carbon filtering layer that the drum type brake multiple layer combination is installed, also can also be to be that glass fibre filter material layer 10, intermediate course are constituted by the bar gate type filter course of the movable dismounting that composite fibre active carbon filtering layer 11 is combined into by skin.Why the utility model adopts fiber-reactive charcoal filtering layer filtrate, is because it is more much higher in efficient aspect minimizing dust concentration and the reduction dioxins concentration than granular activated carbon, powder active carbon spray equipment after testing.

Operation principle process of the present utility model is as follows: after being discharged from secondary combustion chamber by the high-temperature flue gas (about 850 ℃) of incinerator generation, the cyclone dust collectors that at first enter the first order are isolated the coarse granule (temperature drops to about 600 ℃) in the flue dust, under the effect of air-introduced machine, enter again in the spray chamber of venturi (pipe) wet dust collector 5, (make high-temperature flue gas about this quenching to 100 ℃ at this nozzle 13 that high atomisation is housed, cross 300 ℃ of-500 ℃ of intervals that are easy to generate dioxin most), flue dust fully mixes with water smoke and contacts, after promptly being adsorbed with water, most of flue dust falls in the sedimentation basin 14, after the band steam flue gas after the preliminary purification passes through dewatering station's processed again, advance to the detachable fiber-reactive char filter of installing of the third level (bar gate type) again and carry out last purification together, at this moment most dioxin (for organic hypertoxic carcinogenic substance) are had the adsorbed removing of fibre active carbon filtering layer of high absorption property, are cleaned clean flue gas up to standard at last and enter chimney row to atmosphere by outlet flue.After wherein dismountable composite fibre active carbon filtering layer filtrate laying dust concentration increases, continue again to use or change after can conveniently taking out cleaning.
