ABSTRACT:
Apparatus for removing and collecting dust from dust laden air includes a traveling manifold which travels through an upper clean-air chamber back and forth from one end of the baghouse to the other. Process air is directed upwardly and inwardly through the walls of an array of filter bags suspended in a lower chamber. At the upper ends of the filters bags are open mouths which communicate with the upper chamber. Pressurized reverse-direction air is injected from the traveling manifold into the mouths of the filter bags through openings in a flat cover plate. A bag support plate, located beneath the cover plate, separates the lower dust-laden air chamber from the upper clean-air chamber. The reverse air is injected successively into the mouths of a single row of filter bags for forcing air outwardly through the fabric walls of the filter bags to cause dust accumulated thereon to drop off and fall into the lower chamber. The traveling manifold is provided with leading and trailing seal plates which register against the flat cover plate and prevent the pressurized reverse air from escaping into the upper clean-air chamber and force it to flow downwardly into the interior of the filter bags. Means are provided for maintaining the seal plates close to the flat cover plate as the manifold travels thereover, and for adjusting the angular position of the seal plates. End seal plates are also provided.
