Apparatus for removing foreign particles for air

Apparatus for removing foreign particles from air, comprising

• a housing having spaced opposite inlet and outlet ends, air containing foreign particles being admitted into said housing at said inlet end and cleaned air being discharged from said housing at said outlet end;
• a liquid source in said housing;
• a stationary helical vane in said housing having a plurality of helical ribbons extending from said helical vane;
• a rotary vane having a plurality of blades mounted for rotation within an area surrounded by said helical ribbons;
• and
• spraying means for spraying liquid from said liquid source into said housing, whereby foreign particles in air entering said housing at said inlet end are coated with said liquid, said air entering said housing throws the liquid-coated foreign particles onto said helical vane and said helical ribbons and off said helical vane and helical ribbons, said air entering said housing rotates said blades of said rotary vane which collect and coalesce liquid mists on the surfaces thereof and said foreign particles are flung off said blades of said rotary vane and dispersed by said helical ribbons onto all surfaces in said housing and into said liquid source while clean air is discharged at said outlet end.

Apparatus for removing foreign particles from air, comprising

• a substantially cylindrical portable housing disposed substantially horizontally with its axis substantially horizontal, said housing having an inlet end and a spaced opposite at the ends of an axis spaced from and parallel to the axis of said housing and means for admitting air containing foreign particles into said housing at said inlet end and means for discharging cleaned air from said housing at said outlet end;
• clamping means on said housing at said inlet end for affixing said housing at its inlet end in a substantially sealed manner to an enclosure having air containing foreign particles;
• liquid supply means comprising an open bath at the bottom of said housing, a liquid supply, liquid level sensing means connected to said liquid supply for sensing the level of liquid in said bath, liquid control means for controlling said liquid supply to supply liquid to said bath upon said level of said liquid falling below a predetermined magnitude and spray means including pressurized nozzle means at said inlet end for spraying liquid from said liquid supply into said housing, whereby foreign particles in air entering said housing at said inlet end are coated with said liquid;
• a helical vane affixed in said housing and having a plurality of helical ribbons extending from said vane and fixedly mounted in said housing, whereby air entering said housing throws the liquid-coated particles onto said helical vane and helical ribbons and off said helical vane and ribbons;
• a rotary vane having a plurality of blades mounted for rotation with an area surrounded by said helical ribbons, whereby said blades collect and coalesce liquid mists, including said liquid-coated foreign particles on the surfaces thereof and said air entering said housing rotates said blades and said foreign particles are flung off said blades of said rotary vane and dispersed by said helical ribbons onto all surfaces in said housing and into said liquid bath while clean air is discharged at said outlet end.

• a stationary helical vane in said housing;
• a rotary vane having a plurality of blades mounted for rotation within an area adjacent said helical vane;
• and
• spraying means for spraying liquid from said liquid source into said housing, whereby foreign particles in air entering said housing at said inlet end are coated with said liquid, said air entering said housing throws the liquid-coated foreign particles onto said helical vane and off said helical vane, said air entering said housing rotates said blades of said rotary vane which collect and coalesce liquid mists on the surfaces thereof and said foreign particles are flung off said blades of said rotary vane and dispersed by said helical vane onto all surfaces in said housing and into said liquid source while clean air is discharged at said outlet end.
