Abstract

791,510. Air filters. HALLSTROM, O. H. May 29, 1956 [June 14, 1955], No. 16559/56. Class 8(2). An air filter comprises a casing 1 divided into a lower dust-laden air inlet chamber 7 and into an upper filtered air suction chamber 8 by a filtering wall 6 formed by vertical concentric tubes 11 of porous polyvinyl chloride bridged alternately at their upper and lower ends, and flushing liquid is supplied from a pipe 14 to one or other of the chambers 7, 8 through pipes 12, 13 respectively according to the setting of a three-way cock 15. Liquid from pipe 12 washes dust having fallen from the upstream side of filter wall 6 into the hopper 16 through an outlet 18 closed by an automatic flap valve 17 of the gravity type. A reverse flow of liquid through the filter wall 6 is effected by liquid in pipe 13 gaining access to a spray ring 20 through a piston valve 22 which serves to seat a valve 25 against the clean air outlet 10.
