A housing for an industrial baghouse constructed of a plurality of panels having a stiffening element integral with the wall. Each panel is similarily constructed in the shape of an elongated 'U'. The panels are arranged upright in juxtaposition to, and in an alternating manner with, each adjoining panel. A channel is formed between two adjoining panels by overlapping the ends of each panel with the next adjoining panel. This channel creates a stiffening element to give structural rigidity to the housing wall. A housing wall so constructed can withstand the internal pressure associated with a baghouse.

Baghouse with integral wall stiffeners

Tensioning tool

Tensioning cap for a bag filter

An industrial baghouse having a single clean air plenum in which a portion of the filter bags can be serviced while the baghouse remains on line. Service compartments in the clean air plenum can be individually isolated from the remainder of the clean air plenum by installing removable slide gates through normally sealed slots formed in the top of the baghouse. When a service compartment has been enclosed by the gates, it is isolated from the clean air plenum and access doors above the compartment can be removed to provide access for on line inspection and servicing of the filter bags and related components. Removable gaskets which normally seal the slots can be removed prior to insertion of the gates and replaced following removal of the gates.

Baghouse with on-line maintenance capability

For an inside to outside dust collector, a self tensioning bag retainer for connecting the upper end of a fabric sleeve filter to an overhead support. For preinstallation of the filter assembly, a compressed tensioning spring is retained from movement by a pin member to facilitate ease of installation. With the pin member removed, however, the spring acts upwardly against a retainer cap to appropriately tension the sleeve filter and to permit controlled flexure during cycling from a filtering to a cleaning operation.

Self tensioning cap for bag filters

A disposable filter cartridge for suspension from the tube sheet in a baghouse. A wire mesh cylindrical cage is rigidly fitted with a diffuser having plurality of flexible fingers which sealingly encircle the tube sheet collar. A fabric filter sleeve encases the cage and has an upper seal skirt of greater diameter than the outside diameter of the diffuser. The cage may be equipped with a bottom end cap having an annular groove adjacent the cage to facilitate crimping thereon. The bottom of an open filter sleeve may be provided with a cuff having a continuous sealing band disposed therein of slightly larger diameter than the bottom end cap.

Disposable filter cartridge

For retarding oxidation of hotmix asphalt, an inert gas injection system for a storage bin equipped with a self-sealing intake door and pressure equalizing valves. Inert gas is periodically introduced into the bin by electrically timed control.
