A ram circuit for an aircraft includes a ram inlet housing (24), a ram outlet housing (36), a heat exchanger (34), a ram air fan (26), and a particle separator (44). The ram inlet housing includes a chamber and an inlet configured to receive air. The ram outlet housing is fluidly connected to the ram inlet housing. The heat exchanger is disposed between and fluidly connected to the inlet housing and the outlet housing. The ram air fan is disposed in the outlet housing and includes a motor (30) with a cooling inlet. The particle separator includes an outer inlet (58) and a clean air outlet (64). The outer inlet is configured to receive ram air from the chamber of the ram inlet housing and faces into a flow of air passing through the chamber. Clean air is discharged through the clean air outlet which is fluidly connected to the cooling inlet of the motor.

Séparateur cyclonique à co-courant permettant de séparer une phase légère L1, contenue dans un mélange M1 comprenant également une phase dense D1 comportant en aval, dans le sens de circulation de la phase dense D1, du niveau de l'entrée interne (3) de l'enceinte intérieure, des moyens (6) limitant la progression de la phase légère L1 à l'extérieur de ladite enceinte intérieure. Le mélange M1 est introduit en (1) et on récupère la phase dense D1 en (9) et la phase légère en (4). Cet appareil permet la séparation rapide, à partir d'un mélange M1, comprenant une phase dense et une phase légère, de ladite phase dense et de ladite phase légère, par exemple la séparation d'un solide et d'un gaz.
摘要:
A method and apparatus for separating the components of a feed material prior to or simultaneously with at least partially vaporising 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 vaporised to further assist in separating the two components into a liquid component and a gaseous or vapour component. The liquid component and the vapour 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 vapour 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 reactor (10) in which a furnace section (28), a heat recovery section (30) and a horizontal cyclone separator (68) are formed in a vessel. A bed of solid particulate material including fuel is supported in the furnace section (28) and air is introduced into the bed at a velocity sufficient to fluidize same and support the combustion or gasification of the fuel. A mixture of air, the gaseous products of combustion and the particles entrained by the air are directed to the vortex chamber (70) of the cyclone separator (68) through an inlet duct (72). The helical end (78) of the vortex chamber (70) forces the mixture to spirally circulate within the chamber, where the solid particles of the mixture are separated by centrifugal forces. A central tube (76) extends partially within the vortex chamber (70) and receives the cleaned gases from the low pressure center of the chamber. The portion of the tube (76) behind the helical end (78) of the vortex chamber (70) opens directly into the heat recovery area (30) for passing the clean gases thereto. A trough (74) extends from the lower portion of the vortex chamber (70) to the fuel bed for receiving the separated particles and returning them to the bed.

Improved apparatus for collecting particles from air comprises a cyclone (13) having air inlet (14) and outlet (15) means, means maintaining an airflow there through and means (28) delivering a collecting fluid from a reservoir (26) to particles separated from the air flow in the cyclone (13), in which the air inlet means (14) is associated with means for heating (30) 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 grade C.

A cyclonic fluid separator for separating condensable, liquid and/or solid components from a fluid mixture comprises an upstream fluid inlet section in which the fluid mixture is accelerated to a supersonic velocity to expand and cool the fluid mixture such that one or more condensable fluid components are liquefied and/or solidified, a downstream separation section in which condensables depleted and condensables enriched fluid fractions are separated and fed into separate outlets, and a midstream vortex generation section which comprises a plurality of tilted wings of which the wing tips (5A,5B)are located at relatively large mutual spacings (D) and at a small spacing (S
摘要:
A cyclonic fluid separator for separating one or more condensable components, such as water, and/or solids, such as smoke or sand particles, from a fluid mixture has a tubular housing (1) having a fluid inlet section in which the fluid mixture is accelerated to a supersonic velocity and thereby expanded and cooled such that condensable components condense and/or solidify, one or more wings (9) for inducing the fluid mixture to swirl within a central section (8) of the tubular housing, a fluid separation section in which a tubular vortex finder (2) is movably arranged, a condensables enriched fluid outlet (18) which is connected to an annular space surrounding the tapered tubular vortex finder (2) and a condensables depleted fluid outlet (16) which is connected to the interior of the tapered tubular vortex finder (2). The vortex finder may be movable in a radial and/or longitudinal direction (4,5) within the housing to align the entrance (14) of the vortex finder with the centre of rotation (13) of the swirling fluid, which centre of rotation may be unaligned to and/6r spiral about the central axis (3) of the tubular housing as a result of the radial fluid displacement by the wing(s) (9) .
摘要:
Un séparateur, servant à séparer des particules solides d'un courant de gaz chaud, comprend une chambre à cyclone comportant un conduit de sortie de gaz axial (16). Le conduit de sortie est formé par plusieurs tubes de refroidissement (19) qui définissent entre eux plusieurs passages (20) pour le gaz. Le conduit de sortie est relié à une ouverture ménagée dans l'une et/ou l'autre des extrémités de la chambre à cyclone. Les particules solides sont séparées par des forces centrifuges, au fur et à mesure que l'écoulement de gaz suit un chemin incurvé dans la chambre à cyclone, et par des forces d'inertie au fur et à mesure que le gaz change de direction pour s'écouler dans le conduit de sortie.
