Abstract
Apparatus and method for purging floaters in top inlet baghouse construction wherein the upper plenum of a baghouse compartment and the clean exhaust gases duct are operably connected with a purge duct, a controllable purge damper inserted therein. At termination of the usual cleaning operation, clean exhaust gases are introduced into the top plenum by opening of the controllable purge damper to purge floaters from the upper plenum and down through the bag filters and out the bottom plenum to the reverse air duct. At the termination of the floater purge cycle, the purge damper is closed and the compartment returned to on-line operation. In alternate embodiments, a bottom inlet baghouse construction is purged of floaters wherein clean exhaust gases are given entrance into the upper portion of the bag filters with a controllable purge damper interposed. One embodiment connects with the clean exhaust duct and the other embodiment opens to the filter plenum. At termination of the usual cleaning operation, clean exhaust gases are introduced into the upper portion of the bag filters by opening the controllable purge damper. Then the purge damper is closed and the compartment returned to …
