A dust collector includes a cylindrical housing forming an outer appearance of the dust collector; a cyclone formed inside the housing to cause a swirling flow to separate dust from air introduced into the housing; axial inlet type swirl tubes to receive air and fine dust that have passed through the cyclone, and causing a swirling flow to separate the fine dust from the air; and a mesh configured to surround an outside of the axial inlet type swirl tubes to form a boundary between the cyclone and the axial inlet type swirl tubes, wherein the axial inlet type swirl tubes are configured with four groups and stacked in multiple stages on virtual quadrants, the axial inlet type swirl tubes arranged in the same quadrant are arranged to face the same direction, and the axial inlet type swirl tubes arranged in different quadrants are arranged to face different directions.

A separator provides mechanical separation of suspended particles or debris within a fluid. The separator includes a cylindrical body having an inlet pipe for directing the fluid generally tangentially into the cylindrical body, causing the fluid to spin around the inside diameter of the cylindrical body. An outlet pipe, having an outer diameter smaller than the inside diameter of the cylindrical body, can extend from a top end of the cylindrical body into the cylindrical body. Directional blades can be disposed on an outer surface of the outlet pipe, with a gap between the directional blades and the inside surface of the cylindrical body. A baffle dome disposed an a lower end of the cylindrical body slows down the fluid flow, causing the particles and debris to remain below the baffle and settle. The fluid then exits out the outlet pipe as a cleaned fluid.

A method for separating a vapor from a carrier gas is disclosed. An air-sparged hydrocyclone is provided with a porous sparger covered by an outer gas plenum. A cryogenic liquid is provided to the tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the cyclone. The carrier gas is injected into the air-sparged hydrocyclone through the porous sparger. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted gas is drawn through a vortex finder while the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.

In an air cleaner (32), three cyclone dust collection units (34) are arranged on one side of a filter dust collection unit (35) in a mutually parallel relationship. The cyclone dust collection units are arranged along a circumferential direction of the filter dust collection unit, and the central cyclone dust collection unit has a smaller diameter than the remaining cyclone dust collection units positioned on either side of the central cyclone dust collection unit so that the dust collection units can be accommodated in a rectangular profile is a highly space efficient manner.
