Abstract
The cloth bag and active carbon filter combined three-stage high-effective dust-removing cleaning equipment for incinerator includes multi-stage dust-removing device, flue and draguthf an, and is characterized by that said multi-stage dust-removing device includes first-stage cyclone separator, second-stage pulse type cloth bag dust remover and third-stage fiber active carbon cleaning device for cleaning and removing dioxayin. It is a complete tail gas cleaning system, and possesses extensive application range.
Description
Technical field: the present invention relates to a kind of flue-gas dust removal and purification device, particularly a kind of three-stage high-effective dust-removing cleaning equipment that mainly makes up that is used for incinerator by cloth bag and active carbon filter.
Background technology: environmental protection has at present become a fundamental state policy of China, to various incinerators (comprising coal-burning boiler, incinerator) the udst separation of a large amount of flue dust that produces and other pernicious gases (as sulfur dioxide or dioxin organic carcinogen etc.) be subjected to the extensive attention of governments at all levels day by day.Many comparatively effectively dust-removal and desulfurizing purifiers (these cleaners have wet type or dry type) have appearred at present, if any whirlwind (band moisture film or not with moisture film) cleaning type, storage water heater impingement washing scrubber and fiber bag precipitator or the like.These dedusters are because of structural reason; or its ways and means that is used in combination dedusting is oversimplified and scientific and reasonable inadequately (just single-stage or secondary simple combination); its actual smoke abatement and dust control clean-up effect is particularly removed the dioxin aspect and also had weak point (also can't be up to standard): existing hollow drum type cyclone dust collector only is applicable to the removing of bulky grain dust; the fluctuation of the flue gas rate of climb is unstable in running into tube; even can't form the helical form air-flow; can make the dust removing effects of small particles be subjected to very big influence; though sack cleaner is the technology (its efficiency of dust collection is higher) that generally adopts in the incinerator; can reach the relevant dust emission standard of country; but be subjected to the cloth bag material to limit (generally require air inlet temperature＜200 ℃); between incinerator (the outlet flue temperature reaches 850 ℃) and sack cleaner, need heat exchanger; temperature is reduced to guarantee below 200 ℃ that sack cleaner normally uses; owing to well-known reason, tail gas from incinerator (flue gas) is reduced in 300 ℃ of-500 ℃ of intervals and is easy to be combined into again dioxin.Therefore though the bag-type dust efficiency of dust collection is very high, existing flue dust exhaust gas cleaner (or system) the generally technological process of its udst separation but seems powerless to the elimination of dioxin only till the bag-type dust, is difficult to accomplish qualified discharge.
The object of the invention is to overcome the deficiency of prior art, thereby provide a kind of three-stage high-effective dust-removing cleaning equipment that mainly comprises cloth bag and active carbon filter combination, make to have and make simply, install and control conveniently, when being used for incinerator, dust can be efficiently eliminated, the emission compliance of dioxin can be made again.
The present invention realizes with following technical scheme, compositions such as it comprises multistage dust arrester, cross flue, air-introduced machine chimney is characterized in that: described multistage dust arrester is meant the pulsed sack cleaner handled according to the tactic cyclone dust collectors of handling as the first order, as the second level and combines as (fiber) active carbon purifying device that the third level is mainly used in the adsorption cleaning dioxin.
The present invention repeatedly purifies in the analysis of testing result at various incinerator smokes according to national environmental protection monitoring expert, think if general its technological process of exhaust gas purification system device if only to the end till the bag-type dust of one-level, though can solve the dust concentration limit value requirement that is up to state standards, but the elimination absorption that human body is produced the organic carcinogen dioxin of significant damage seems powerless, therefore the present invention adopts the high-effective dust-removing cleaning equipment that comprises three grades of reasonable combination of active carbon filter in tail gas clean-up, it can absorb effectively attached to the dioxin in the flue dust, therefore the dioxin that smoke stack emission is gone out is up to standard, thereby form a perfect exhaust gas purification system device, be specially adapted to the gas cleaning usefulness of incinerator, also applicable to the udst separation of other Industrial Boilers.
Description of drawings: Fig. 1 is a kind of structural representation of the present invention.
Wherein: the secondary combustion chamber of 1-incinerator, 2-incinerator, 3-cyclone dust collectors (remove coarse granule flue dust usefulness, be prior art), 4-one-level heat exchanger, 5-two-stage heat exchanger, 6-pulsed sack cleaner (for prior art), 7-(fiber) active carbon purifying device (also claiming active carbon filter), 8-air-introduced machine, 9-chimney, 10-cross the fibre active carbon filtering layer of flue, the outer field glass fibre filter material layer of 11-(or filter plate), 12-intermediate course.
The specific embodiment: with reference to accompanying drawing as can be known, the present invention also has following technical characterictic when specific design:
One, between the cyclone dust collectors 3 of the first order and partial pulsed sack cleaner 6 these two-stage dust arresters, also need be provided with two-stage heat exchanger at least, can make higher temperatures flue gas rapid cooling the after two-stage heat exchanger is handled that comes out from cyclone dust collectors like this until reaching the requirement of sack cleaner inlet temperature, in order to avoid filter bag is burnt out.
Two, the active carbon purifying device 7 of described third level adsorption removal dioxin can be to make conveniently detachable filter layer of cloth by the multi-layer fiber active carbon to constitute, or sending out filtering layer by the fiber-reactive that the drum type brake multiple layer combination is installed constitutes (accompanying drawing slightly), also can also be to be that glass fibre filter material layer 11, intermediate course are constituted by the conveniently detachable filter course that fiber-reactive charcoal filtering layer 12 is combined into by skin.Why the present invention adopts fiber-reactive charcoal filtering layer material, 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 invention is as follows: the high-temperature flue gas (about 850 ℃) that is produced by (rubbish) incinerator at first enters cyclone dust collectors and separates coarse granule the flue dust after secondary combustion chamber is discharged, enter first and second grade heat exchanger then and carry out twice continuously rapidly after the cooling, enter sack cleaner (inlet temperature requires≤170 ℃, in order to avoid filter bag is burnt out).Flue gas is handled a large amount of thin flue dust in back by sack cleaner and is retained down (dust concentration is up to standard substantially), also remaining a small amount of flue dust that still contains dioxin enters fiber-reactive carbon purifying device again, after active carbon adsorption is handled, by the air-introduced machine effect, the flue gas extraction is entered chimney row to atmosphere, because the fiber-reactive charcoal is to organic matter absorption property extra-heavy (dioxin is an organic carcinogen), dust concentration that comes out like this and dioxins concentration are just extremely low, have guaranteed that both all can reach the qualified discharge standard of national regulation.
