Abstract
The utility model relates to a centrifugal type dust collecting device which is composed of a smoke inlet pipe, a banana bend dust collector, an overhauling manhole, an internally-arranged scraper ash conveyor, a scraper machine head part, an automatic balance type overhauling hole, a scraper machine tail part and a smoke outlet pipe, wherein the curve radius of the banana bend dust collector is 1.0-1.2 times as much as the diameter of the smoke inlet pipe. The centrifugal type dust collecting device has a short rotating route and has the equipment resistance of 200-300 Pa; the dust collecting efficiency of dust with the grain diameter more than or equal to 25 microns in the smoke reaches 95% or more; and the centrifugal type dust collecting device has the advantages of simple structure and low operation cost.
Description
Technical field
The utility model relates to dust arrester, specifically belongs to centrifugal dust arrester.
Background technology
Iron and steel enterprise has a large amount of technological process meetings to produce ash-laden gas, environment is produced pollute.For solving problem of environmental pollution, discharging is up to state standards, must be to it through dust removal process.
Conventional at present deduster has sack cleaner, electrostatic precipitator, gravitational precipitator and cyclone dust collectors etc.Use conventional cleaner to have problems such as investment is high, resistance is big, operating cost is high, efficiency of dust collection is low at present.Resistance was bigger when sack cleaner existed operation, caused system energy consumption to raise; The electrostatic precipitator control program is complicated, and investment cost is higher; For the gravitational precipitator that leans on the gravity effect that grit is separated from air-flow, its dust removing effects is relatively poor, and only to producing effect greater than 150 μ m granule dusts.Carry out the cyclone dust collectors of dust separation generally is made up of air induction mast, cylindrical shell, cone and blast pipe for same dependence centrifugal force; Flue gas air-flow after air induction mast gets into rotatablely moves along outer wall from top to bottom; Swirling eddy transfers to rotate to the axle center, upper edge at cone base; Particle is shifted to outer wall gradually under action of centrifugal force, the dust that arrives outer wall falls into ash bucket at gravity and action of centrifugal force lower edge wall.Though it can reach 90% to dust size greater than the efficiency of dust collection of 30 μ m, because the air-flow rotating distance is long, its equipment resistance reaches 1000Pa～1500Pa, and energy consumption is wanted height relatively.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency; Provide a kind of through the change to the radius of curvature of banana-bends deduster in the cleaner, make the air-flow rotating distance short, equipment resistance is little; Be applicable to dust size >=25 μ m, its efficiency of dust collection 95% and more than centrifugal dust arrester.
Realize the technical measures of above-mentioned purpose:
Centrifugal dust arrester; Be made up of smoke inlet pipe, banana-bends deduster, inspection manhole, built-in scraper ash-transmission machine, scraper plate chain-drive section, self-balancing type manhole, scraper plate drive end unit, smoke outlet tube, 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 utlity model has following beneficial effect: rotating distance is short, and equipment resistance is merely 200Pa～300Pa, to the efficiency of dust collection of the dust of particle diameter in the flue gas >=25 μ m reach 95% and more than, and simple in structure, operating cost is low.
