A device for separating gas and liquid from a mixture of gas and liquid phases includes a fluid guide member comprising a fluid inlet and a fluid outlet connected by a conduit configured as an elongated spiral disposed about an axis. A liquid coalescing medium is disposed on an exterior surface of the fluid guide radially outward from the elongated spiral conduit with respect to the axis. The separator also includes a plurality of radial channels providing radial flow paths for fluid from the elongated spiral conduit to the coalescing medium.

The present patent of invention application refers to a draining and sealing device (1), belonging to the field of forward flow or reverse flow mist eliminators or polygonal plate systems used in various industries, which consist of a tubular body (10) formed by an optional upper portion (11) comprising a cover e having a closed upper end (12) and radial drainage openings (13); an intermediate attachment portion comprising a thread (14) or welding ring (15) or flange (16); and a lower tubular portion (17) provided with a lower end having drainage holes (18); said drainage and sealing device (1) also being formed by a body of drainage and sealing fibers (20) housed in the lower tubular portion (17) that provides drainage of the collected liquid and sealing against the countercurrent circulation of mist-containing gas; said drainage and sealing device (1) may have the tubular body (10) without no upper portion (11).

An oil separator provided with a housing with an inlet for an oil-gas mixture and which defines a space that is closed off by means of a lid, whereby a screen is provided in the aforementioned space in which a filter element is affixed and a pipe or collector that connects the interior of the filter element to an outlet in the housing for purified gas, whereby the oil separator is provided with a drainage line for the removal of the oil that has been filtered out, wherein the drainage line ensures the removal of the oil that has been filtered out from the underside of the filter element directly to an outlet for oil in the housing.

A coalescing filter assembly including a coalescing filter element is provided. The coalescing filter assembly includes a base housing and a cover housing that together form a coalescing chamber. Disposed within the coalescing chamber is the coalescing filter element. The coalescing filter element includes a frame with a partition that separates an unfiltered side from a filtered side of the coalescing filter assembly. A port connects the unfiltered side to the filtered side through the partition. A coalescing tube including coalescing filter media is connected to the port. Unfiltered fluid that enters the coalescing filter assembly is passed through the coalescing filter media such that the contaminants are removed to create a filtered fluid. The filtered fluid exits the coalescing filter assembly at an outlet of the coalescing filter assembly.

A separating apparatus for separating liquid from gas has a housing with a connection device for connecting to a connection head of a machine along a connection axis. The housing has a gas inlet and a gas outlet surrounding the connection axis. A separating medium inside the housing separates gas inlet from gas outlet. A liquid collection chamber inside the housing at a clean gas side surrounds connection axis and gas outlet. A liquid drain leads out of the liquid collection chamber. Gas outlet and liquid drain lead out of the housing at a side provided with the connection device. A pipe section arranged inside the housing surrounds circumferentially the connection axis and forms at least partially a radially inner boundary of the liquid collection chamber. The pipe section leads to the gas outlet. The pipe section is functionally separated from mechanical force-transmitting connection elements of the connection device.

The present invention relates to operation of air-oil separators and oil filters used in systems requiring oil separation and filtration on a single block. In other words, the present invention discloses an oil separation and filtration system having an air-oil separator and an oil filter.

A concentrating apparatus for concentrating compressed air includes a first hollow cylindrical concentrating unit which is adapted to cause compressed air to: (i) collide with an upstream side of a collision plate so as to be concentrated and partially liquefied; (ii) move to an annular passage and be jetted into an air moving chamber so as to be adiabatically expanded and partially liquefied; (iii) be compressed in an air compressing passage and pushed out so as to retreat along a conical partition wall; (iv) collide with a downstream side of the collision plate so as to be concentrated and partially liquefied; (v) be introduced into an upstream end of an outlet tube; and (vi) move to a downstream end of the outlet tube and into a second hollow cylindrical concentrating unit.

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid, and a second container, the second container being arranged to separate at least a part of one or more components contained in the fluid from the fluid. The two containers are interconnected by a throttle device adapted to throttle a transfer of at least a part of the fluid from the first container into the second container.

A device for separating a fluid component from a fluid, in particular compressed air of a vehicle, is provided. The device has a first container for containing the fluid, the first container being arranged to separate at least a part of one or more components contained in the fluid from the fluid by evaporation. The first container includes one or more openings through which a substance can be supplied to the fluid in the first container for breaking an emulsion or mixture of two or more components contained in the fluid and an exhaust through which the at least part of the one or more separated components can be exhausted.

An oil mist recovery, separation and purification device for a minimum quantity lubricant (MQL) grinding process, including: a pneumatic separation mechanism, a pipeline and a fan fixedly connected with one end of the pipeline, wherein the fan is configured to form a negative pressure in the pipeline, one cone-shaped filter mesh mechanism is disposed in the pipeline, and a tip of the cone-shaped filter mesh mechanism faces the side of an air inlet direction of the pipeline; and a filtering and recovery mechanism connected with the pipeline and including a case body, a filtering mechanism and a recovery mechanism, wherein the case body is connected with the pipeline through a connecting part, and the filtering mechanism is connected with the recovery mechanism. The device can separate, recover and reuse oil mist particles in the air.
