Combination Filter Cartridge Dust CollectorA Dust Collector Composed Of Filter Cartridges As Filtering Elements Or Using Pulse Blowing. The Filter Cartridge Dust Collector Can Be Divided Into Inclined Insertion Type, Side Installation Type, Lifting Type, And Upper Installation Type According To The Installation Method. Filter Cartridge Dust Collectors Can Be Divided Into Long Fiber Polyester Filter Cartridge Dust Collectors, Composite Fiber Filter Cartridge Dust Collectors, Anti-static (based On Actual Reports) Filter Cartridge Dust Collectors, Flame-retardant Filter Cartridge Dust Collectors, Membrane Filter Cartridge Dust Collectors, Nano Filter Cartridge Dust Collectors, Etc.
The Structure Of The Combined Filter Cartridge Dust Collector, Including The Intake And Exhaust Ducts, Is Based On The Actual Situation. The Sudden Expansion Of The Main Cross-sectional Area Is A Technical Improvement Measure For The Dust Cleaning Device.
Structure
The Structure Of The Combined Filter Cartridge Dust Collector Consists Of An Inlet Duct, An Exhaust Duct, A Box Body, An Ash Hopper, A Cleaning Device, A Guide Device, An Airflow Distribution Plate, A Filter Cartridge, And An Electrical Control Device, Similar To The Structure Of An Air Box Pulse Bag Dust Collector.
The Arrangement Of The Combined Filter Cartridge Dust Collector Is Very Important. It Can Be Vertically Arranged On The Box Flower Board Or Tilted On The Flower Board. From The Perspective Of Dust Cleaning Effect, Vertical Arrangement Is More Reasonable. The Lower Part Of The Flower Board Is The Filtering Chamber, And The Upper Part Is The Pulse Chamber Of The Air Box. An Airflow Distribution Plate Is Installed At The Inlet Of The Dust Collector.
Working Principle
After The Dusty Gas Enters The Dust Collector Hopper, Due To The Sudden Expansion Of The Airflow Cross-section And The Effect Of The Airflow Distribution Plate, Some Coarse Particles In The Airflow Settle In The Hopper Under The Action Of Dynamic And Inertial Forces; After The Dust Particles With Fine Particle Size And Low Density Enter The Dust Filter Chamber, They Deposit On The Surface Of The Filter Material Through A Combination Of Brownian Diffusion And Screening Effects. The Purified Gas Enters The Clean Air Chamber And Is Discharged Through The Exhaust Pipe And Fan.
The Resistance Of The Combined Filter Cartridge Dust Collector Increases With The Increase Of The Thickness Of The Dust Layer On The Surface Of The Filter Material. Clean The Dust When The Resistance Reaches A Certain Specified Value. At This Time, The PLC Program Controls The Opening And Closing Of The Pulse Valve, The Lifting Valve Of The First Chamber Is Closed, The Filtered Airflow Is Cut Off, And Then The Electromagnetic Pulse Valve Is Opened. Compressed Air And A Short Period Of Time Expand At A Suitable Speed Inside The Upper Box, Flowing Into The Filter Cartridge, Causing The Filter Cartridge To Expand And Deform, Generating Vibration. Under The Action Of Reverse Airflow Flushing, The Dust Attached To The Outer Surface Of The Filter Bag Is Peeled Off And Falls Into The Ash Hopper. After The Dust Cleaning Is Completed, The Electromagnetic Pulse Valve Closes, The Lift Valve Opens, And The Chamber Returns To The Filtering State. The Cleaning Process Is Carried Out Sequentially In Each Room, Starting From The Cleaning Of One Room And Ending With The Next Cleaning Cycle. The Fallen Dust Falls Into The Ash Hopper And Is Discharged Through The Ash Removal Valve.
During This Process, It Is Necessary To Regularly Replace And Clean The Filter Cartridge To Confirm The Filtration Effect And Accuracy, Because In Addition To Being Blocked, Some Dust Will Also Deposit On The Surface Of The Filter Material, Increasing Resistance. Therefore, The Correct Replacement Time Is Generally Three To Five Months!
The Characteristics Of The Combined Filter Cartridge Dust Collector Are As Follows:
① Due To The Pleated Cylindrical Shape Of The Filter Material, The Density Of The Filter Material Arrangement Is High, Resulting In A Compact Structure And Small Volume Of The Dust Collector;
Cartridge Filter
② The Height Of The Filter Cartridge Is Small, Easy To Install, And The Maintenance Workload Is Small;
③ The Filtering Area Of The Same Volume Dust Collector Is Relatively Large, The Filtering Wind Speed Is Small, And The Resistance Is Not High;
④ The Folding Of Filter Media Requires Strict Sealing At Both Ends And No Air Leakage, Otherwise It Will Reduce The Effectiveness.
