Overview
The flat bag air filtration system efficiently filters dust-laden air through its specially designed filter bags. The contaminated air enters from the top and is purified as it flows through the filter media, leaving the chamber as clean air. Dust particles are trapped on the filter surface, forming a protective dust cake that enhances overall filtration. Periodic automated cleaning removes the accumulated dust, ensuring uninterrupted operation.
Smart Cleaning Technology
This dust removal equipment uses an innovative offline cleaning system, where gas pulses are injected into the filter bags to dislodge dust buildup. The cleaning trolley, connected to the cleaning valve via a spiral sleeve, is guided by a chain-driven mechanism with built-in expansion compensation. The system is equipped with maintenance-free bearings, a directional control device, and limit switches, ensuring smooth and precise operation.
Offline Cleaning Benefits
-
Reduced particle re-adhesion: Dust is fully removed without re-contaminating adjacent bags.
-
Optimal filtration efficiency: Supports the formation and maintenance of a stable dust cake layer for pre-filtration.
-
Lower operational wear: Prolongs the lifespan of the filter bags and reduces downtime.
Importance of Clean Gas Pulses
Using clean gas for backflushing improves dust removal by maintaining a consistent powder layer. In industries like foundries, fine dust (<1µm) agglomerates into larger particles, which can be effectively filtered by the system. A powder cake thickness of approximately 0.1 mm (~100 grams/㎡) enhances filtration and extends bag durability.
Applications
-
Metal Foundries: Suitable for sand handling, casting, grinding, and shot blasting dust control.
-
Energy Sector: Ideal for flue gas purification in boilers and other high-temperature systems.
-
Mining Operations: Perfect for dust collection at crushers, screeners, conveyor belts, and silo systems.
-
Aluminum Industry: Specialized fume extraction systems for primary and secondary aluminum processes.
-
Miscellaneous Industries: Effective for tobacco, incineration, and powder manufacturing facilities.
