Abstract

An apparatus for removing particles from a surface utilizing a manifold having three regions is disclosed. The three regions include a triangular inlet region, a collection duct region and an exhaust duct region. The triangular inlet includes a narrow constant gap slot along the length of the manifold through which stream of parallel air flow through uniformly. The collection duct is adjacent to the triangular inlet and collects the air flow exiting from the triangular inlet. The exhaust duct, in one embodiment, is centrally located at the apex of the triangular manifold, partially situated on the collection ducts where they meet. The exhaust duct provides an exit for the air being transported by the collection ducts. The combination of these three regions provide uniform air flow velocity through the manifold.

An apparatus for removing particles from a surface utilizing a manifold having three regions is disclosed. The three regions include a triangular inlet region, a collection duct region and an exhaust duct region. The triangular inlet includes a narrow constant gap slot along the length of the manifold through which stream of parallel air flow through uniformly. The collection duct is adjacent to the triangular inlet and collects the air flow exiting from the triangular inlet. The exhaust duct, in one embodiment, is centrally located at the apex of the triangular manifold, partially situated on the collection ducts where they meet. The exhaust duct provides an exit for the air being transported by the collection ducts. The combination of these three regions provide uniform air flow velocity through the manifold.

Referring to Figure 1, which shows a schematic elevational view of the uniform air flow manifold. The uniform air flow section of the manifold has three regions. The first is the triangular inlet region or narrow gap region 10. This is a narrow constant gap slot having uniform, constant velocity, and parallel air flow streams through it. The base of the triangular inlet region 10 is indicated by an imaginary line, L1, drawn from the opposing end points of the second region called the collection duct 20. The collection duct 20 is located
.ust above the triangular inlet region 10. The bent architecture of the collection duct 20 forms the top two diagonal sides of the triangular inlet region 10. The collection duct 20 (shown here as a circular cross-section duct) collects air flow exiting the triangular inlet region 10 and transports the collected air flow to a third region, the exhaust duct 30. The preferred embodiment of the exhaust duct 30 in the invention is for the exhaust duct 30 to be centrally located near the apex of the triangular configuration of the manifold 100 and, partially on the collection ducts 20 where they meet.
