Disclosed in a filter for filtering a working fluid comprising a canister having an inlet and an outlet; a first partially perforated generally conical member positioned in said canister; a second generally conical member positioned inside said first partially perforated generally conical member, whereby the working fluid upon entering the inlet is caused to spin inside the canister, to pass through the perforated portion of the first generally conical member, to enter an inlet to the second generally conical member, to spin within the second conical member and to pass through the outlet.

Improved apparatus for collecting particles from air comprises a cyclone having air inlet and outlet means, means maintaining an airflow there through and means delivering a collecting fluid from a reservoir to particles separated from the air flow in the cyclone, in which the air inlet means is associated with means for heating the incoming air. The apparatus, which is optionally provided with enclosure means for trapping heat, prevents freezing of the collecting fluid at temperatures near to and even below 0° C.

A cyclone which includes an upper cylindrical portion opening into the wider end of a lower frustro-conical portion, with a primary air inlet such that the inlet air is substantially tangential to the circumference of the cyclone, and an exhaust outlet at or adjacent the top of the cylindrical portion; a control valve is associated with the exhaust outlet and can be used to partially or completely shut off the outlet; a secondary air inlet is associated with the narrow end of the frustro-conical portion and is provided with an air flow stabilising device adapted to admit a stream of air substantially along the longitudinal axis of the cyclone; also including means for withdrawing processed product from the frustro-conical portion.

A method and apparatus for separating the components of a feed material prior to or simultaneously with at least partially vaporizing one of the components is described. The apparatus comprises at least one inlet (8) for admitting the feed material (10) containing the two components to the apparatus (2) wherein a device for introducing a first movement to the feed material is located, such as, for example, an in-line swirl generator (14), which imparts a swirling movement to the feed material to partially separate the components into two swirling flows. The partially separated material on emerging from the in-line swirl generator (14) is in an evaporation tube (20) in which the more volatile component is vaporized to further assist in separating the two components into a liquid component and a gaseous or vapor component. The liquid component and the vapor phase are discharged from the apparatus in two streams through the same outlet (36). Modifications of the method and apparatus include (i) having multiple evaporation tubes (20), each optionally provided with its own in-line swirl generator to facilitate better distribution and separation of the feed material, and (ii) having a reject nozzle (40) and reject conduit (42) located within the generator for allowing passage of vapor or gas through the in-line swirl generator (14) when there is an intermediate flow formed in the generator (14) and conveyed to the evaporation tube (20). The method and apparatus of this application are used as a pre-treatment in an overall separation plant.
摘要:
A two-stage hydrocyclone system for separating oily fluids including a first stage hydrocyclone set up to produce a concentrated oil stream, while the second stage hydrocyclone is set up to optimize the production of clean water from the dirty water underflow stream of the first stage hydrocyclone. The hydrocyclone stages are mounted within a pressure vessel with divider walls, with the first stage producing a concentrated oil stream substantially free of water and a dirty water stream containing some oil. This dirty water stream from the first stage is fed to the second stage to obtain a clean water stream.

An apparatus that includes (i) a centrifugal separator assembly and (ii) a fluidized bed reactor having a reactor chamber, the separator assembly being connected to the reactor and provided for separating solid particles from gas discharged from the reactor chamber. The apparatus includes planar peripheral walls defining a vortex chamber, having a rectangular cross section, the vortex chamber having an interior gas volume in which at least two vertical gas vortices can be formed, and the planar peripheral walls including a first wall portion connecting the separator assembly to the reactor chamber, at least two gas outlets, disposed one after the other in the longitudinal direction of the vortex chamber, for discharging cleaned gas from the gas volume, at least one solid particles outlet for discharging separated solid particles from the gas volume, and at least one gas inlet, arranged in the first wall portion, for introducing gas from the reactor chamber into the gas volume. The at least one gas inlet includes at least two inlet ducts which are mainly perpendicular to the first wall portion and arranged side-by-side in the first wall portion within a less than ninety degree sector of one gas vortex within the vortex chamber.
摘要:
A cyclone separator for a solids-laden process gas from a fluidized bed boiler or reactor also provides a pressure seal and heat exchanger surfaces for the reactor or boiler. The cyclone includes a cylindrical main housing with a longitudinal axis. The housing is made of membrane wall construction. A portion of the tubes are bent outwardly to form an inlet which communicates with the main housing for receiving the solids-laden process gas from the boiler or reactor. Solids are separated from the solids-laden process gas as they swirl together in the main housing of the cyclone separator. A partition wall is disposed at the lower section of the main housing around the longitudinal axis for defining an outer chamber and an inner chamber adjacent the outer chamber. Gas is provided to the outer and inner chambers for creating fluidized beds of the solids in the outer and inner chambers. Solids are passed from the inner chamber to the outer chamber through an underflow port in the partition wall. Solids exit the main housing from an overflow port which communicates with the reactor. Immersed heat exchanger surfaces are provided in the outer chamber for removing heat therefrom.
摘要:
An interstage separator for transferring polymeric crumb from a first stage pneumatic conveyor with hot wet air, to a second stage pneumatic conveyor with cool dry air. The interstate separator is characterized by a tangential inlet for the crumb, and an enclosed separating chamber within which the crumb is separated from the first stage air stream. A transition member associated with the separator directs the crumb into a second stage air stream and, then, to a second stage pneumatic conveyor. The interstage separator transfers the rubber crumb from the first stage air stream to the second stage air stream without fouling of the associated equipment.
摘要:
A vessel for separating entrained particles from a gas in which a vertically extending tubular portion extends through a portion of a housing for providing an outlet for the gas after separation from the particles. The tubular portion includes a tube formed into a spiral coil, and a continuous fin extends from the tube for the entire length of the tube. The fin is welded to adjacent sections of the tube to render the coil airtight. A layer of insulation material extends to both sides of the coil.
