The filter cage, which acts as a holder for filter bags in bag filter systems, plays a vital role in the proper and optimal functioning of these systems. The filter cage is a sturdy holder for bags in bag filter systems, made from various types of wire, and helps facilitate proper airflow.
These wires are produced in different thicknesses and lengths to meet diverse needs. Filter cages come in various types, such as those with star rings, circular rings, and book-type rings. Star ring cages, with their unique design, protect the bags and enhance filtration efficiency. Various coatings improve their resistance to harsh environmental conditions.
How Filter Cages Work
The operation of a filter cage is as follows: First, the filter bag is placed over the cage, and then this assembly is installed inside the dust collector housing. Contaminated air enters the dust collector chamber and passes through the pores in the filter bag fabric. Suspended particles and pollutants, due to their size and structure, cannot pass through these pores and are captured by the bag’s fibers.
The filter cage, with its structure, protects the bag against pressure and suspended particles, preventing pore clogging. It also ensures uniform airflow and improves filtration efficiency. During bag cleaning, the cage helps dislodge and collect particles through shaking or an automated system.
Advantages of Filter Cages
Filter cages, as a critical component of bag filter systems, offer numerous benefits for various industries, some of which are highlighted below:
Protection of Filter Bags: By being placed inside the filter bags, filter cages protect them from air pressure and the accumulation of suspended particles. This prevents tears and damage to the bags, extending their lifespan.
- Uniform Airflow Distribution: Filter cages help distribute airflow evenly inside the bag, preventing dead zones and reducing filtration efficiency loss. This enhances filter performance and improves the capture rate of suspended particles.
- Extended Filter Bag Lifespan: By protecting filter bags and aiding in their cleaning, filter cages help prolong bag life and reduce maintenance costs.
- Improved Bag Filter System Performance: Filter cages enhance overall bag filter system performance by optimizing airflow, preventing pore clogging, and assisting in bag cleaning.
