Abstract
An improved baghouse which is adapted to remove particulate matter from an air flow. The baghouse has three main chambers being the plenum, the receiving chamber, and a hopper. The three chambers are separated from each other using tubesheets having multiple holes therein. Filtering bags are connected to the upper and lower tubesheets. Attachment of the bag to the upper tubesheet is accomplished using a thimble that is preferably assembled with the bag and then delivered to the site ready for easy insertion into the hole of the tubesheet. A strap to sandwich the bag to the upper thimble. At the lower end, there are attached thimbles on the tubesheet and the bags are secured to those thimbles using clamps. Through the use of beads on the thimbles and bags, shaped clamps and straps, the bag is secured to both thimbles such that slippage and leakage are eliminated; further the shaped bottom clamps prevent relative motion between the bag and the top of the bottom thimble so that excess bag wear is avoided.
