Steel slag powder bag dust collector

In 1, an overviewSteel slag ironmaking, steelmaking process is the inevitable product of steel production, mainly from hot metal and scrap elements contained in oxidized after the formation of the oxide, metal charge into the impurity. At present domestic steel slag dust the dust remover for the vast majority of air box pulse type; but some are low pressure pulse long bag type, but the bad effect. For my company based on steel slag grinding of flue gas components, high content of special flue dust, dust particles, hardware features such as research and development of new low pressure pulse long bag dust collector.2, work principleDust flue gas through the air inlet duct, in the wind tunnel wind suddenly reduced and inclined partition collision, large particles of dust by the weight on the natural settlement through the air duct," human" plate rolled from hopper. Large particle sedimentation reducing flue gas itself dust concentration of reducing bag filter load. Smoke in the inclined partition under the action of uniformly into the middle lower part of the box body, is arranged at the middle part in the box body baffle in flue gas is divided into two parts; one part of the flue gas through the deflector along into the bag, the other part containing a large particles of flue gas through the deflector along into the hopper, again through the filter bag dust particles settling bottom up, after the bag filtering.3, equipment compositionDust collector consists of a dust remover body system, air deflector system, filtration system, cleaning system, instrument control system and protection system.4, technical characteristicsThe dust collector is the solution to the current air box pulse bag dust collector area, the existing low pressure pulse long bag are poorly used malpractice. Using a new type of dust collector structure in the structure is good for reducing the speed bag to prevent dust from directly flushing the filter bag, the benefit of high dust concentration dust deposition, in the filter selection considering the particularity of the steel slag grinding flue gas. In view of the above problems to solve the method includes: an air inlet, lambdoidal board design, the design of helical baffle deflector plate, abrasion resistant treatment, bag, filter spacing selection.In 5, the performance guaranteeDust emission concentration to ensure value for30mg/Nm3;Dust collector system running resistance < 2200Pa, running resistance:1600-2000Pa;The dust remover body leakage rate≤ 2%;Dust removal equipment service life of 30years;Filter service life of more than30000 hours;Electromagnetic pulse valve service life of more than5 years.6, application fieldSteel slag, slag and other industry dust treatment.
