How Shaker Filter Bags Collect Dust
Shaker baghouses collect dust similar to reverse air baghouses. Dust collects on the inside surface of the shaker filter bags, and then clean air exits through the top of the bag. The main difference is how the bags cleaned.
How to Clean Shaker Filter Bags
Shaker baghouses are engineered so that filters are hung and tensioned from the top of the unit, and at the bottom they are attached to a tube sheet. Mechanically shaking the filter bags is what cleans them. Shaker baghouses only clean while the system is off-line. Shaker baghouse operation is simple and can be seen in applications where no compressed air is available.
Construction of Shaker Filter Bags
Fabric filter bags used in shaker baghouses are typically constructed with woven or light weight media options like polyester sateen, shaker felt, beane knit, and more. Treatments are dependent on a plant’s application and dust characteristics. The most common top and bottom configurations for shaker baghouses are below.
