Title:
BAG HOUSE ELEMENTS
Document Type and Number:
WIPO Patent Application WO2002020129
Kind Code:
A3
Abstract:
The filter structures commonly known as a bag house or a filter bag or an air filter with a bag construction can be made by preparing the bag assembly, either in a tubular or a bi-fold construction by placing a layer of fine fiber on the upstream surface of the filter media structure. The filter assembly includes a filter cabinet with an interior component. The filter component is suspended within the filter cabinet interior. The filter component includes a frame or support for the filter media. The frame or support holds the filter bags such that the filter bags are suspended from the frame in the cabinet interior. The intake air enters the cabinet, passes through the filter assembly and exits the cabinet. The air must pass first into the fine fiber layer, the filter media and then the exterior of the cabinet.
