Abstract
The invention discloses a combined flue gas dust removal device. The combined flue gas dust removal device mainly comprises a first vertical double-sleeve cyclonic spray settling dust collector and a second multi-pipe direct-blowing type dust collector; high-temperature flue gas enters through a flue gas inlet (1), reaches the bottom of the dust collector along a spiral cyclone plate (10) and enters a flue gas guide pipe (4) to be discharged; the flue gas enters the second multi-pipe direct-blowing type dust collector through a flue (7), is filtered through water, passes through two water sprayers (16 and 14) and two cyclone plates (15 and 13) and is finally discharged through a flue gas outlet (12). The combined flue gas dust removal device has the technical characteristics that the structure is compact and the dust removal effect is good, an induced draft fan does not take water when the flue gas is fed into the device, and the flue gas retention time is long.
Description
Technical field
The present invention relates to boiler smoke dedusting technology field, it is a kind of combined fume dust remover, and it is to be used on the boiler that burns timber, waste paper, cloth etc., the device that can effectively the flying dust in flue gas be removed.
Background technology
In recent years, along with the needs of industrial production development and urban environmental protection, the harm understanding that people's environmental pollution causes is also more and more clear, more and more higher to requirement and the desire of improvement and protection of the environment.Special process burning such as some timber, waste paper, cloth and produce in a large amount of flue gases and contain a large amount of flying dust and pernicious gas, how effectively to reduce the discharge of dust and pernicious gas in flue gas, is that many R&D institutions are in the problem of constantly studying.
The object of the invention is to utilize the technology of existing maturation, reasonably combine, the a large amount of flying dust and the pernicious gas that while reducing burning, produce, realize qualified discharge, it is to be contained in boiler tail for this device, by boiler induced-draft fan, directly high-temperature flue gas is fed through in combined fume dust remover, can avoid air-introduced machine water phenomenon, flue gas is introduced into after vertical pair of sleeve whirlwind spray sedimentation pretreatment of first, most flying dust in flue gas is first effectively removed, by flue, enter into after the direct-firing dedusting of second multitube again, thumping majority flue dust is removed, the flue dust left behind is processed through two road water sprays again, last flue gas up to standard is discharged by exhanst gas outlet.This programme remove more up hill and dale flue gas with flying dust and pernicious gas, flue gas is purified.This apparatus structure is compact, and flue gas fully contacts with water, and the time of staying is long, the feature of good dedusting effect.
Summary of the invention
Task of the present invention mainly discloses a kind of combined fume dust remover, it is to be contained in boiler tail, by boiler induced-draft fan, directly high-temperature flue gas is sent in combined fume dust remover, can avoid air-introduced machine water phenomenon, through dedusting flue gas good up to standard by flue, be connected to again chimney discharged to atmosphere in.
Task of the present invention is achieved like this, a kind of combined fume dust remover, it has mainly been combined by vertical pair of sleeve whirlwind spray settling dust remover pretreatment of: first and the direct-firing deduster of second multitube, high-temperature flue gas is first entered by smoke inlet (1), along spiral spiral board (10), arrive behind deduster bottom, entering into flue gas mozzle (4) discharges again, flue gas enters into the direct-firing dust arrester of second multitube by flue (7) again, flue gas sprays (16) by two road water again after water filtration, (14) after, again through two road spiral boards (15), (13), finally by exhanst gas outlet (12), discharged.
Technical characterictic of the present invention has compact conformation, and flue gas is sent into, and air-introduced machine can be with water, and gas residence time is long, good dedusting effect.
Be a kind of combined fume dust remover structure accompanying drawing below, the invention will be further described in conjunction with the accompanying drawings and embodiments.
Fig. 1 is a kind of combined fume dust remover structural representation.
(1) in figure, overfall, (2), deduster staving 1, (3), water spray nozzle 1, (4), flue gas mozzle, (5), water spray nozzle 2, (6), gas approach, (7), flue, (8), water spray nozzle 3, (9), water spray nozzle 4, (10), spiral spiral board, (11), directly blow smoke pipe, (12), exhanst gas outlet, (13), spiral board 1, (14), water spray nozzle 5, (15), spiral board 2, (16), water spray nozzle 6, (17), concrete foundation, (18), deduster staving 2.
The specific embodiment
The present invention is achieved like this, and with resistant material, makes a vertical pair of sleeve whirlwind spray settling dust remover and a direct-firing deduster of multitube, between two dedusters, with flue, connects.Vertical pair of sleeve whirlwind spray settling dust remover, its deduster staving 1 is toroidal, in staving bosom position, one section of flue gas mozzle is housed, its bottom is smoke inlet, top is exhanst gas outlet, between the deduster staving 1 of toroidal and flue gas mozzle, spiral spiral board is housed, along on deduster staving 1 wall, surrounding is equipped with water spray nozzle from top to bottom.High-temperature flue gas is first entered by smoke inlet (1), arrives behind deduster bottom, then enter into flue gas mozzle (4) discharge along spiral spiral board (10), and flue gas enters into the direct-firing dust arrester of second multitube by flue (7) again.It is the deduster staving 2 by toroidal for the direct-firing dust arrester of multitube, in its centre position, be equipped with one group be evenly arranged from top to bottom directly blow smoke pipe (11), at the end opening that directly blows smoke pipe, pipe directly extend in pond, the bottom surface in pond is to become an inclined-plane with concrete casting, there is a water outlet in bosom, and there is an overfall outside of openning, the sewage precipitating containing volume of smoke can be discharged.Directly blow between smoke pipe and the inwall of deduster staving 2, divide upper and lower two layers two road spiral boards (13), (15) are housed, on the deduster staving wall of the bottom of spiral board, water spray (14), (16) are also respectively housed one, high-temperature flue gas enters and directly blows after smoke pipe, effective filtration through water, flue dust is removed in a large number, flue gas enters into behind two road spiral boards (13), (15) He Er road water spray (14), (16) again, and flue gas up to standard is discharged by exhanst gas outlet (12).
Claims (1)
1. a combined fume dust remover, it is characterized in that: it has mainly been combined by vertical pair of sleeve whirlwind spray settling dust remover pretreatment of first and the direct-firing deduster of second multitube, high-temperature flue gas is first entered by smoke inlet (1), along spiral spiral board (10), arrive behind deduster bottom, entering into flue gas mozzle (4) discharges again, flue gas enters into the direct-firing dust arrester of second multitube by flue (7) again, flue gas sprays (16) by two road water again after water filtration, (14) after, again through two road spiral boards (15), (13), finally by exhanst gas outlet (12), discharged.
