Rotary Kiln Bag FilterFlue Gas Process Flow:
After Being Drawn Out From The Kiln Head, The High-temperature Flue Gas Is First Cooled By A Forced Circulation Water-cooled Machine (pre Dust Removal), Then Purified By An Effective Bag Filter, And Finally Discharged By An Exhaust Fan. The Tail Of The Rotary Kiln Pulse Bag Filter Adopts A Large Capacity Sealed Hood Bag Filter, Which Has Achieved Relatively Ideal Results. The Large Volume Sealed Hood At The Kiln Tail Can Buffer Intermittent Impact Airflow And Reduce The Exhaust Volume Of The Dust Collector; Connect The Sealed Hoods Of Several Vacuum Boxes (not Less Than 5) In The Rotary Kiln To The Sealed Hood At The Kiln Tail As A Whole, So That Some Of The Dusty Gas At The Tail Of The Machine Can Pass Through The Material Layer And Vacuum Box, And Be Extracted By The Process Smoke Exhaust, Which Can Also Reduce The Exhaust Volume Of The Bag Filter At The Kiln Tail. In Order To Minimize The Exhaust Volume Of The Dust Collector As Much As Possible And Make Full Use Of The Capacity Of The Process Smoke Exhaust, Bends, Trolleys, And Other Air Leaks Should Be Strictly Sealed To Increase The Dust Removal Effect Of The Dust Collector. Similarly, Other Dust Producing Points At The Tail Of The Rotary Kiln Should Also Be Made Into Large Capacity Hoods As Much As Possible, And Bag Filters Should Be Used To Concentrate Dust Collection And Generate Circulating Airflow Inside The Hood To Eliminate And Reduce Positive Pressure.
Characteristics Of Rotary Kiln Bag Filter:
① Good Dust Cleaning Effect: Using A Large-diameter Submerged Pulse Valve, The Spraying Resistance Is Small, The Air Pressure Is Low, And The Instantaneous Spraying Pressure For Dust Cleaning Reaches 2000pa, With Strong Dust Cleaning And Good Effect
② Easy Maintenance: Adopting An Upper Cover Structure, The Filter Bag Frame Can Be Easily Removed To Facilitate Bag Replacement At A Suitable Speed; The Main Fan Is In A Clean Airflow Working Environment, And The Blades Of The Main Fan Do Not Require Cleaning And Maintenance. The Fan Operates Relatively Stably.
③ Investment Saving: A New Type Of Composite Filter Material With Significantly Improved Matching Performance, Flexural Resistance, And Peel Strength, Which Can Withstand High Temperatures (based On Actual Reports), Increase Filtration Speed, And Have A Long Service Life; The Skeleton Adopts An Integral Die Welded Skeleton, And The Upper Part Of The Skeleton Is Equipped With An Integral Venturi Tube, Which Has Good Overall Performance, Corrosion Resistance (based On Actual Reports), High Surface Smoothness, And Does Not Damage The Filter Bag; The Filter Unit And Dust Collector Flower Plate Are Assembled With Spring Clamps For Easy Disassembly And Maintenance, And Have Good Sealing Performance; Due To The Good Quality Of The Accessories, The Overall Operating Costs Have Been Significantly Reduced.
④ Design: In Response To The Special Situation Where The Outlet Flue Gas Temperature Of The Rotary Kiln Hot Furnace Can Reach Over 450 ° C, An Outdoor Natural Cooling System Has Been Specially Designed, Which Does Not Consume Energy Or Power And Can Save Costs. On This Basis, An Automatic Controlled Cold Air Valve Is Also Added For Use In Case Of High Temperature, Protecting The Operating Characteristics Of The Equipment.
