According to one implementation, a centrifugal oil mist separator includes a duct, a fan and a power transmission mechanism. The duct forms a flow path of a first exhaust gas discharged from an engine. The first exhaust gas includes oil mist. The fan is disposed inside the duct. The power transmission mechanism rotates the fan using energy of a second exhaust gas discharged from the engine. The second exhaust gas includes no oil mist.

A cleaner is provided. The cleaner includes a suction head, a dust collector connected to the suction head, and a fan motor provided to generate a suction force inside the dust collector, wherein the dust collector comprises a housing having an inlet and an outlet, a fixed body arranged inside the housing, and a rotating body rotatably provided between the housing and the fixed body.

A casing includes a tubular part including a gas inlet; a gas outlet apart from the gas inlet in an axial direction of the tubular part and in communicative connection with an inside and an outside of the tubular part; and a solid substance discharge port aligned with the gas outlet in a direction along an outer periphery of the tubular part. A blade rotates together with a rotor and has a first end adjacent to the gas inlet and a second end adjacent to the gas outlet. The casing has a space extending to the solid substance discharge port with respect to the second end of the blade in the axial direction of the tubular part. A separation device further includes a discharge tubular part having an inner space in communicative connection with the solid substance discharge port and protruding from an outer peripheral surface of the tubular part.

The present invention refers to an accelerating cyclone that separates solid particles, comprising in its general structure a lower conical body (1) (17A and 17B), comprising a lower opening (18), a central cylindrical body (2) immediately above the conical body (1) whose diameter is smaller than the largest diameter of the conical body cone (1), and a third upper, also cylindrical, body (3) of smaller diameter than the diameter of the central cylindrical body (2), comprising a side opening for the acceleration air output (5); where the cylindrical central body (2) allows to accelerate the speed of the solid material particles and is the cyclone pressure chamber; and where said cylindrical central body (2) comprises a side opening for the acceleration air input (8) and at least one duct (9).

A device collects material from air. The device swirls air within a fluid housing so as to deposit the material, such as viruses, bacteria, fungi and other particles, from the air in a way that the material can later be analyzed. The device can be used to provide for detection of airborne organisms or properties of material in the air.

A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.

A separation apparatus for separating an unwanted substance from an extraction target includes a forming unit configured to form a separation chamber through which the extraction target passes, and a suction unit communicating with the separation chamber in a direction crossing a passage direction of the extraction target and configured to suck air in the separation chamber. The forming unit includes an inlet for the extraction target, which communicates with the separation chamber, and an outlet for the extraction target, which communicates with the separation chamber, and the air is sucked from the outlet into the separation chamber by suction of the suction unit.

A diffuser for a jet pump of a separator comprises an inlet defining a first flow area; an outlet in fluid communication with the inlet through which fluid exits the diffuser, in which a flow path extends from the inlet to the outlet, and in which the outlet defines a second flow area greater than the first flow area so that a velocity of fluid flowing through the inlet is greater than a velocity of fluid flowing through the outlet; and a communication port extending through a wall of the diffuser with an inlet in communication with an interior of the diffuser and an outlet in communication with an exterior of the diffuser, in which the communication port inlet is between the diffuser inlet and the diffuser outlet, so that contaminants separated from the fluid stream are removed through the communication port.

An active rotating separator is disclosed, comprising a separator drum arranged to receive multiphase fluid via an upstream end and to deliver separated fluid phases from a downstream end of the drum. An electric motor is installed in the flow through the drum, the motor operable to generate rotation in the fluid flow that passes through the drum, the motor comprising an open rotor permitting through-flow of fluid through the motor.
