Abstract
The invention relates to a centrifugal dust removal device which comprises a smoke inlet pipe, a banana bending dust remover, an inspection manhole, a dust delivery machine with a built-in scraping plate, a head of a scraper, a self-balance type inspection hole, a tail part of the scraper and a smoke outlet pipe, and is characterized in that the curvature radius of the banana bending dust remover is 1.0 to 1.2 times as large as the diameter of the smoke inlet pipe. The centrifugal dust removal device has the advantages that the rotation travel is short, the equipment resistance is only 200 Pa to 300 Pa, the efficiency of removing dust with the grain size larger than or equaling to 25 um in the smoke can be more than 95%, the structure is simple, and the operating cost is low.
Description
Technical field
The present invention relates to dust arrester, specifically belong to centrifugal dust removal device.
Background technology
Iron and steel enterprise has a large amount of technological process meetings to produce ash-laden gas, and environment is produced and polluted.For solving problem of environmental pollution, discharge is up to state standards, must be to it through dust removal process.
Conventional deduster has sack cleaner, electrostatic precipitator, gravitational precipitator and cyclone dust collectors etc. at present.Use at present conventional cleaner to have the problems such as investment is high, resistance is large, operating cost is high, efficiency of dust collection is low.When sack cleaner exists operation, resistance is larger, causes system energy consumption to raise; Electrostatic precipitator control program complexity, investment cost is higher; For the gravitational precipitator that grit is separated from air-flow by Action of Gravity Field, its dust removing effects is poor, and only to being greater than 150 μ m granule dusts, produces effect.The cyclone dust collectors that carry out dust separation for same dependence centrifugal force are generally comprised of air induction mast, simplified, cone and blast pipe, flue gas air-flow after air induction mast enters rotatablely moves from top to bottom along outer wall, swirling eddy transfers upwards along axle center, to rotate at cone base, particle is shifted to gradually outer wall under the effect of centrifugal force, and the dust that arrives outer wall falls into ash bucket along wall under the effect of gravity and centrifugal force.Although its efficiency of dust collection that dust size is greater than to 30 μ m can reach 90%, because flow rotation stroke is long, its equipment resistance reaches 1000Pa～1500Pa, and it is high that energy consumption is wanted relatively.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and make flow rotation stroke short by the change to the radius of curvature of banana-bends deduster in cleaner, equipment resistance is little, be applicable to dust size >=25 μ m, its efficiency of dust collection is 95% and above centrifugal dust removal device.
Realize the technical measures of above-mentioned purpose:
Centrifugal dust removal device, smoke inlet pipe, banana-bends deduster, inspection manhole, built-in scraper ash-transmission machine, scrapper conveyor head, self-balancing type manhole, scrapper conveyor afterbody, smoke outlet tube, consist of, it is: the radius of curvature of banana-bends deduster is 1.0～1.2 times of smoke inlet pipe diameter.
It is characterized in that: the flue gas flow rate that control smoke inlet pipe and smoke outlet tube go out is all at 25～28m/s.
It is characterized in that: on built-in scraper ash-transmission machine, be provided with 3～4 manholes.
The present invention has following beneficial effect: rotating distance is short, and equipment resistance is only 200Pa～300Pa, to the efficiency of dust collection of the dust of particle diameter >=25 μ m in flue gas reach 95% and more than, and simple in structure, operating cost is low.
