Abstract: Disclosed is an air-cleaning blower (“ACB”) that includes an inlet cover, housing, clean-side cover, and impeller. The inlet cover may be a rigid flat surface with a central opening. The housing may have a hollow inner cavity and walls that form an incomplete cylinder with a slit between the walls. The clean-side cover may be a rigid flat surface with apertures, and with brackets extending between the apertures to connect an impeller/motor mount to the clean-side cover. The impeller may be mounted on the impeller/motor mount inside the housing between the inlet cover and the clean-side cover. The impeller rotates to induce suction of particulate-pervaded air or gas through the central opening, to circulate the heavier particulates against an interior of the walls until ejection through the slit, and to circulate the lighter cleaned air or gas in front of the heavier particulates until ejection through the apertures.

Abstract: Provided is an air or gas cleaning blower with a spiral separation chamber. An impeller draws in particulate-pervaded air or gas and imposes a centrifugal force that accelerates the particulate-pervaded air or gas outwards in the chamber. The particulates, because of their heavier mass relative to the air or gas, accumulate against the outer chamber wall. Most of the lighter air or gas is unable to penetrate through the layer of particulates and is trapped in between the particulates about the outer wall and the inner wall of the chamber. The impeller pushes the separated particulates and cleaned air or gas further down the chamber with the particulates ejecting out a first outlet about the outer chamber wall and the cleaned air or gas circulating around the first outlet, moving further down the chamber, and ejecting out a second outlet.

Abstract: Some embodiments provide a centripetal air or gas cleaning apparatus for removing particulates from air or gas. The apparatus comprises an inlet, housing, impeller, a clean air outlet, and a particulate outlet. The housing has an inner conical surface. The impeller's rotation creates negative pressure towards the inlet that intakes particulate-pervaded air or gas into the housing. The rotation also induces an accelerating force that throws the particulate-pervaded air or gas against the outer walls of the housing. Here, the particulates separate from the air or gas, penetrate a high-pressure zone, and are ejected through the particulate outlet located in the high-pressure zone. The air or gas, having less inertia, deflects away from the high-pressure zone where it is then subjected to a centripetal force that drives the air or gas towards the center of the housing behind the impeller where it is ejected through the clean air outlet.
