Abstract
The invention discloses a double-swirl flue gas dust remover capable of spray settling. High-temperature flue gas enters from a flue gas inlet, is subjected to spray settling through two water spray nozzles, and tangentially enters a first double-sleeve cyclone dust removal main tower from the bottom; the main tower is composed of a main tower body and a circular column installed in the middle of the tower; the upper part adjacent to the circular column is provided with two swirl plates; the tower body on the upper part is respectively provided with two water spray nozzles; the upper part of the main tower is provided with a splash plate capable of preventing water from being taken away by the flue gas; the top of the main tower is connected with a second cyclone dust remover through a top plate; the second cyclone dust remover is composed of a cyclone tower body and a middle flue gas guide pipe; spiral guide plates are installed between the cyclone tower body and the middle flue gas guide pipe; a water spray nozzle is installed between every two guide plates; the upper part of the flue gas guide pipe is provided with a flue gas outlet; and smoke dust and sewage subjected to spray settling are discharged by an overflow port. The dust remover has the technical characteristics of compact structure, long flue gas retention time and favorable dust removal effect.
Description
Technical field
The present invention relates to boiler smoke dedusting technology field, it is a kind of band spray sedimentation double-cyclone 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, and this device is first through spray sedimentation pretreatment by flue gas, a part of flying dust in flue gas is first effectively removed, and increase flying dust band water probability, and then after processing by the two sleeve whirlwind of first, then carry out the processing of second whirlwind, 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 band spray sedimentation double-cyclone fume dust remover, and it is to be contained in boiler tail, utilizes flue to connect, by the draft of boiler induced-draft fan, and the device that flying dust in flue gas and pernicious gas are removed.
Task of the present invention is achieved like this, a kind of band spray sedimentation double-cyclone fume dust remover, it is mainly completed by: flue gas spray expansion chamber and the two sleeve cyclone dust removal of first and second cyclone dust removal, the first horizontal direction of high-temperature flue gas is entered by smoke inlet (1), after the sedimentation of Jing Er road water spray nozzle (2) spray, tangentially by bottom, enter into the two sleeve cyclone dust removal king-towers of first again, king-tower forms by one section of circular abutment (3) being housed in the middle of king-tower tower body (9) and tower, at the upper position near circular abutment, two road spiral boards (4) are housed, (6), upper column at it is equipped with respectively two road water spray nozzles (5) with it, (7), upper position at king-tower is also equipped with the water fender (8) that anti-sealing is taken away by flue gas, top board for top (10) at king-tower is connected with second cyclone dust removal, second cyclone dust removal is comprised of whirlwind tower body (14) and middle flue gas mozzle (12), spiral type flow guide plates (13) is housed between the two, between deflector, fill water spray nozzle (15), on flue gas mozzle top, have an exhanst gas outlet (11), the flue dust settling down through spray and sewage are by overfall (16), (17) discharge.
Technical characterictic of the present invention has compact conformation, and gas residence time is long, good dedusting effect.
Be a kind of band spray sedimentation double-cyclone 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 band spray sedimentation double-cyclone fume dust remover structural representation.
