Description

The three-stage high-effective dust-removing cleaning equipment of impact water bath 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 impact water bath 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, storage water heater impingement washing scrubber and fiber bag precipitator or the like.When these dedusters are used singly or in combination, because of structural reason or the combined method mode is oversimplified, 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.

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 impact water bath and active carbon filter combination, it have simple in structure, cost is low, floor space is little, 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, casing, impact dewatering station, composition such as air-introduced machine, smokejack, 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 the storage water heater impingement washing scrubber of (adsorption removal particle dust and desulfurization) and combine in the second level as active carbon (absorption) clarifier 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 perfect exhaust gas cleaner, complete machine structure is simple, occupation of land easy for installation is little, and purification efficiency height, energy consumption are low, do not need cycling use of water, be 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: the 1-incinerator, 2-incinerator secondary combustion chamber, 3-cyclone dust collectors (being prior art), 4-crosses flue, the 5-casing, 6-impact tube cylindrical shell, 7-advances mouth, 8-taper baffle, 9-impacts dewatering station, the 3rd layer of plate washer of 10-, 11-second layer plate washer, 12-have waveform (profile of tooth) the reaction type plate washer (also claiming the ground floor plate washer) of pilot hole, 13-bosh (being positioned at the casing periphery), 14-storage cistern (interior dress dust suction water), 15-ash disposal mouth, the removable bar gate type active carbon purifying of 16-third level device (filter), 17-glass outer fiber filtering layer, the fiber-reactive charcoal filtering layer of 18-intermediate course, 19-outlet flue (having purified), the S shape of 20-dewatering station is crossed flue.

The specific embodiment: with reference to accompanying drawing as can be known, the utility model also can have following technical characterictics when specific design is implemented:

One, the active carbon purifying device 16 of the impact tube cylindrical shell 6 of the partial storage water heater impingement washing scrubber of described formation, taper baffle 8, dewatering station 9 and the plate washer and the third level is to be installed in jointly in the casing 5 of a bottom band storage cistern 14, also is provided with bosh 13 around the outer of casing.

Two, the active carbon purifying device 16 of described third level adsorption removal dioxin can be to be made of the filtering layer that the multi-layer fiber active carbon of the movable dismounting of bar gate type is made, or constitute (accompanying drawing is slightly) by the fiber-reactive charcoal filtering layer that the drum type brake multiple layer combination is installed, also can also be to be that glass fibre filter material layer 17, intermediate course are constituted by the bar gate type filter course of the movable dismounting that fiber-reactive charcoal filtering layer 18 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.

Three, the described ground floor plate washer that is arranged in impact dewatering station 9 is to make waveform (profile of tooth) reaction type plate washer 12 structures with pilot hole.

Operation principle process of the present utility model is as follows: after being discharged from secondary combustion chamber by the high-temperature flue gas of incinerator generation, the cyclone dust collectors that at first enter the first order are isolated the coarse granule in the flue dust, under the effect of air-introduced machine, enter in the impact tube cylindrical shell 6 by advancing mouth 7 again, after rushing at taper baffle 8, air-flow pours in the dust suction water of storage cistern at a high speed and evokes spray, flue dust fully mixes with water and contacts, most of flue dust promptly is adsorbed with water, band steam flue gas after preliminary purification clashes into by ground floor plate washer (the waveform reaction type plate washer with pilot hole) again, rise to the top second road plate washer, clash into again and rise to the 3rd road plate washer again behind the second road plate washer (downside) and clash into once more, the steam major part that makes the band flue dust is attached to also being back in the storage cistern again on these plate washers, flue gas after being purified is crossed flue 20 by S shape and is advanced to the detachable fiber-reactive char filter of installing of the third level (bar gate type) and carry out purifying together at last, at this moment most dioxin (for organic carcinogen) 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 fiber-reactive charcoal filtering layer filtrate laying dust concentration increases, can continue again to use or change after can conveniently taking out cleaning.
