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

Centrifugal dust arrester
Technical field
The present invention relates to dust arrester, specifically belong 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.The cyclone dust collectors that carry out dust separation for same dependence centrifugal force generally are made up of air induction mast, simplified, cone and blast pipe; 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.
Summary of the invention
The objective of the invention 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 present invention 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.
Description of drawings
Fig. 1 is a main TV structure sketch map of the present invention
Fig. 2 is the left TV structure sketch map of Fig. 1
Among the figure: 1-smoke inlet pipe, 2-banana-bends deduster, the built-in scraper ash-transmission machine of 3-, 4-scraper plate chain-drive section, 5-manhole, 6-scraper plate drive end unit, 7-smoke outlet tube.
The specific embodiment
Do below in conjunction with accompanying drawing and to further describe:
Embodiment 1
Centrifugal dust arrester is made up of smoke inlet pipe 1, banana-bends deduster 2, built-in scraper ash-transmission machine 3, scraper plate chain-drive section 4, manhole 5, scraper plate drive end unit 6, smoke outlet tube 7.The radius of curvature of its banana-bends deduster 2 is according to 1.0 times of value machine-shapings of smoke inlet pipe 1 diameter.For further realizing that efficiency of dust collection reaches 95% and the above object, also can the flue gas flow rate that smoke inlet pipe and smoke outlet tube go out all be controlled at 25m/s.
Embodiment 2
Centrifugal dust arrester is made up of smoke inlet pipe 1, banana-bends deduster 2, built-in scraper ash-transmission machine 3, scraper plate chain-drive section 4, manhole 5, scraper plate drive end unit 6, smoke outlet tube 7.The radius of curvature of its banana-bends deduster 2 is according to 1.05 times of value machine-shapings of smoke inlet pipe 1 diameter.For further realizing that efficiency of dust collection reaches 95% and the above object, also can the flue gas flow rate that smoke inlet pipe and smoke outlet tube go out all be controlled at 26m/s.
Embodiment 3
Centrifugal dust arrester is made up of smoke inlet pipe 1, banana-bends deduster 2, built-in scraper ash-transmission machine 3, scraper plate chain-drive section 4, manhole 5, scraper plate drive end unit 6, smoke outlet tube 7.The radius of curvature of its banana-bends deduster 2 is according to 1.1 times of value machine-shapings of smoke inlet pipe 1 diameter.For further realizing that efficiency of dust collection reaches 95% and the above object, also can the flue gas flow rate that smoke inlet pipe and smoke outlet tube go out all be controlled at 28m/s.
For overhauling the convenient bodily protection that reaches the maintainer, the manhole 5 on the built-in scraper ash-transmission machine 3 is added to 3~4.
Need to prove that embodiment is merely gives an example.
