Reverse Air Bag House - Modular Dust Collector System | Efficient Reverse Flow Cleaning, Low Velocity Dust Separation, Optimized Air Filtration

The Reverse Air Bag House is a modular type construction type dust collector in which each module act as a device which accepts the dust-laden gases, filters it, collects the dust, and discharges the clean air. The dirty air enters the side of the hopper so that, due to the low velocity, much of the entrained dust (particularly the large size of the dust particles) will drop directly in to the hopper. Continuing upward, the air encounters the tube sheet where it passes through the collars and in to the filter bags. The dust in the air does not penetrate the bags but remains as a deposit on their inside surfaces. The air itself, however, does pass through the bag material, then continues upward and out through the top of the compartment. From there it is directed through an exhaust manifold.

At specific intervals, a cleaning cycle is initiated in which the air flow through the module is stopped and air moving in the opposite direction is introduced. This reversed flow and the partial collapse of the bag which it produces causes the accumulated dust to break loose and fall out of the bags. The dislodged dust drops in to the hopper and is removed by dust handling equipment. After the dust has had a few moments to settle, the valves are reset to their position for filtering and the module is returned to service. The air to be filtered is moved through the dust collector by the ID Fan installed downstream of the exhaust manifold. Because air is being pulled
