Shaker - Mechanical Shaker Bag Houses
Shaker bag houses use mechanical shaking or vibrating actions to dislodge the filter cake. Bag bottoms are secured to a plate and their tops are connected to horizontal beams. These beams, driven manually or by a motor, vibrate to produce waves in the bags which shake off particulate matter. The recommended air to cloth ratio for these bag houses is between 2.0:1 and 2.5:1.
Advantages
Design and operation simplicity.
Can be compartmentalized to allow sections to be cleaned without shutting off the whole system.
Disadvantages
Cannot operate in high temperatures.
More energy and time intensive than other cleaning methods.
Small amounts of positive pressure inside the bag can significantly reduce collection efficiency.
Large footprint and space requirements, and requires a large number of bags.
