Abstract: A tubular filter for dynamic cleaning of an air flow containing suspended particles and a system for filtration using this filter includes a flow channel (1), carried out curved and a unit (6, 8) for generating an air flow in the flow channel (1). The tubular filter is arranged in a low pressure chamber (2) and is configured to generate Dean vortices in its curved portion. On outer and inner parts of the curved portion of the flow channel (1) are provided outer (10) and inner (20) openings, respectively, for discharging suspended particles from the flow channel (1) in the low pressure chamber (2). The system for filtration includes a filtration unit (22) with at least one tubular filter (21), a control unit (17) for controlled regulation of the unit (6) for generating a flow in the flow channel (1) and an electric power supply unit (18).

Abstract: A cyclone type liquid/gas or liquid/liquid separator having separation properties that are stabilized, even when the flow rate and the proportions of the liquid phases for separation vary, by means of a platform situated in the low portion of a cylindrical separation chamber that is fed at its top end via a tangential feed orifice. An installation and a method are also provided for separating the oil and water contained in crude oil, with the help of a cyclone separator.

Abstract: A fluid trap apparatus includes an inlet configured to receive a flow of composite fluid into the apparatus. The composite fluid contains at least a first fluid and a second fluid. An outer wall defines an interior chamber. A flow diffuser is interposed within the interior chamber. The flow diffuser directs the flow of the composite fluid to circulate through the interior chamber. The first fluid and the second fluid separate as the composite fluid circulates through the interior chamber. A method of separating a first fluid from a second fluid includes introducing a flow of composite fluid into a separate chamber. A pressure gradient is created within the separation chamber. A flow diffuser is interposed in a flow path between an inlet and an outlet. The flow diffuser directs the flow of the composite fluid within the separation chamber. The first fluid and the second fluid are separated.

Abstract: The invention is a separator designed to separate an incoming stream of liquid, gas, and some particulate matter into a separate gas stream, and a separate liquid stream containing the particulate matter. This is achieved through cyclonic action and the use of a float to operate internal valves within the cyclone. The float is mounted on a shaft which is rotated by the motion of the incoming fluid stream and this motion is used to agitate the solids in the liquid so as to prevent the outlet port from becoming jammed. The outlet port also has an auger contained therein that removes particulate matter.

Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.

Abstract: Gas/liquid separating devices include a separator (1) for separating a mixed gas/liquid flow (M). A liquid drain (2) communicates with the separator and defines a liquid storage chamber (30). The liquid drain serves to temporarily store a liquid separated from the mixed flow within the liquid storage chamber, so that a space that is not occupied by the liquid is ensured within the liquid storage chamber. An adjusting mechanism (52, 152) may serve to adjust the pressure within the space of the liquid storage chamber.

Abstract: A bubble-removing apparatus has a main body having a central axis, a main chamber, an inflow port for introducing a fluid containing entrained bubbles tangentially into the main chamber so that the fluid is caused to rotate in the main chamber about the central axis to cause the bubbles to separate from the fluid and collect around the central axis, an outflow port for discharging the fluid, and a discharge outlet for discharging the bubbles separated from the fluid. A valve chamber is disposed between the discharge outlet and the main chamber, and a block member is disposed in the valve chamber and has a through-hole in fluid communication with the main chamber. A float member is disposed over the block member and undergoes movement within the valve chamber in response to changes in internal pressure within the main chamber to place the through-hole of the block member into and out of fluid communication with the discharge outlet to thereby control the discharge of the bubbles from the discharge outlet.

Abstract: The method of operating rotating separator apparatus, to which fluid, including gas and liquids is supplied in a fluid jet via a nozzle, which includes separating the liquids from the gas in the stream, at a first zone within the rotating apparatus, and separating the liquids into liquids of differing density at a second zone within the apparatus. The separated liquids are removed via two open weirs which isolate the liquids in the separating zones from the shear forces from scoops within the weir passages. Longitudinal ribs may be provided for structural support, coalescence promotion and fluid recirculation inhibition.

Abstract: A gas elimination system includes a gas elimination device and a priming system. The gas elimination device includes a vortex chamber that forms a vortex in the fluid flowing into the chamber and a particulate filter that removes particles from the fluid. The particulate filter is located in the vortex chamber such that the vortex is formed in a substantial volume of the chamber before it encounters the particulate filter. When the fluid encounters the particulate filter, the vortex is generally stopped, and additional released gasses rise through the open top of the particulate filter. The device also includes an outlet chamber connected to the vortex chamber, and the particulate filter extends into the outlet chamber. A check valve is located at the outlet of the outlet chamber to shut off flow when the device contains excess gas. The priming system in the form of a pillow block is arranged to force air or fluid upward to dislodge the check valve, should it become stuck in the valve seat.

Abstract: An apparatus for cleaning hydraulic fluid includes a centrifugal fluid-spinning disk arranged in a housing, of which an upper portion forms a vapor chamber and a lower portion forms a fluid collecting basin. A vacuum pump is connected to the housing through an oil mist separator, such that water vapor is vacuumed away and hydraulic fluid collects in the oil mist separator to then be pumped away. The apparatus further includes preferably a single container that contains both the contaminated hydraulic fluid that is to be cleaned and the cleaned hydraulic fluid. A flexible inlet line and a flexible outlet line with respective hydraulic quick connectors are provided to connect the apparatus and particularly the oil container to a hydraulic system of an aircraft, for example. A high pressure pump connected to the outlet line pumps the cleaned hydraulic fluid into the aircraft hydraulic system and a pressure maintaining valve in the inlet line maintains the system pressure.

Abstract: An apparatus for removing liquid from an air liquid separator is disclosed having a rotatable chamber in communication with the liquid collecting portion of the air-liquid separator such that liquid from the separator may enter the interior of the chamber. A drive motor is associated with the chamber to rotate the chamber such that water collects on the interior of a peripheral wall. A pitot tube extends into the interior of the chamber and has an inlet end adjacent to the inside of the peripheral wall such that water may enter the tubes as the chamber rotates. The other end of the pitot tube extends exteriorly of the apparatus. Rotation of the chamber will cause water to enter the pitot tube and pass through the tube to the exterior of the device.
