Abstract

Apparatus for removing dust particles from an air stream includes a tubular housing having an inlet end and an outlet end; a plurality of Venturi tubes having open inflow ends and open outflow ends supported side-by-side within the housing, with their axes parallel to the housing axis so that their inflow ends receive air flowing into the inlet end of said housing; a nozzle for spraying water into the air entering each of the Venturi tubes whereby dust particles in the air are collected in the water and whereby sludge-containing water and air are discharged through the outflow ends of said Venturi tubes; a tank which surrounds said tubular housing, the tank having an outer wall surrounding and spaced from the tubular housing and partition means in the space between said outer wall and the tubular housing dividing the space into first and second compartments; a sludge separator in communication with the outflow ends of the Venturi tubes; conduit means connected to the sludge separator for supplying sludge-containing water from the separator to the first compartment; a sludge outlet for the first compartment; a conduit for conveying essentially sludge-free water from the first compar…
