Lime kiln baghouse dust collector bag is a source of research and development in Zhengzhou design of a highly efficient dry-type dedusting equipment. Lime kiln baghouse using choke plus diversion of flue gas deflector. This device ensures uniform flue gas into each bag room. In order to ensure the reasonableness of the flue gas diversion device company with a computer simulation of the flue gas deflector design, which is similar to louvered, can play the effect of mechanical removal of high concentrations of smoke have a good effect of dust Ash does not have a blocking happen. Test results show that, after adjusting the air distribution precipitator can meet the state standards. Limekiln high resistance to condensation baghouse best, in the absence of external insulation condition solved due to condensation caused by lime dust bag sticky problem, dust removal efficiency of 97.8%, and has a simple structure, convenient for bags without additional compressed air cleaning and automatic cleaning and so on.
