Introduction

PPC type air box pulse bag type dust collector is a new type of dust colector developed and proclucedby our company to absorb the advantages of various foreign dust collectors.This senes of products has dozens of speciications,which are dvided into several boxes according tö the size of the dust collector.There are four kinds of bags in each room:32. 64.96,and  128  bags.The  length  of  the  fiter  bag  is  2.450  mm  and  3060  mm.The  amount  of  flue  gas  treated  is 3000-3000000m3/h,the concentration of flue gas dust is ≤1200g/Nm3,the dust removal efficiency can reach above 99.9%,and the dust concentration of the  purified  gas  is  less  than  50g/Nm3,which  can  meet  the  requirements  of cement,electric power,metalurgy,chemical industry,etc.A variety of flue gas dust treatment needs are required in the

industry.

Working    PrincipleThe dusty gas enters the ash bucket from the air inlet of this equipment Partof the coarser dust particles due to inertialcollision,Natural sedimentation and other reasons fall into the ash here.Most of the dust particles nise to the bagchamber with the airflow.After fitering through the fiter bag,the dust particles are retained on the outer surface of thefiter bag.The purified gas enters the box from the inside of the fiter bag,and then the valve plate hole and the air outletport are arranged.Into the atmosphere.Achieve the purpose of dust removal.As the filtration process continues,thedust on the outer surface of the fiter bag gradually increases,and the running resistance of the dust collector graduallyincreases When the resistance reaches a preset value,the cleaning controllersends a signal.First control the poppetvalve to close the valve plate hole.In arder to cut off the fitered airflow,stop the fltration process,and then the batterypulse valve opens,injecting compressed air into the tank in a very short time.The compressed air expands rapidly in thetank and flows into the interior of the filter bag,causing deformation and vbration of the fiter bag,In accition,the duston the outer surface of the fiter bag is removed into the ash hopper.After the cleaning is completed.The poppet valveopens again The dust collector enters the filtering working state,and the cleaning control has two control modes timingand constant resistance.
