ABSTRACT:
In this application there is presented a mechanical dust collector which includes an elongated cylindrical housing at the bottom of which a dirty gas stream enters through a primary volute which directs the incoming stream to a cup shroud mounted in the housing axially thereof and generally centrally of the volute, this volute being closed at the bottom and open at the top only to the shroud, whose center is closed so that the inlet stream is given a helical upward draft which throws the solid particles out of the stream toward the interior wall of the housing. Then a secondary volute is provided at the opposite end of the housing leading tangentially from a secondary inlet, this secondary volute being closed at the top and open at the bottom only at an annular space adjacent the inner wall of the housing so that a secondary stream is provided there driving smoothly down the inner wall of the housing and causing the fine solid particles to pass downwardly and below a solid ground which extends horizontally outwardly beyond the cup shroud and which terminates short of the inner wall of the housing. The clean gas passes out the top of the housing through a central outlet.
