摘要:
A separation method and apparatus are disclosed having particular application for effecting removal of sand from a production wellstream, enhancing the quality of recovered oil, gas and water output streams ( 12, 13, 14 ) and reducing erosion caused by entrained sand. The wellstream is passed initially through a cyclone separator ( 4' ) which separates substantially all the water and sand as underflow and substantially all the oil and gas as overflow. A gravity separator ( 11 ) separates the overflow from the cyclone separator ( 4' ) into oil, gas and water, and a further cyclone separator ( 17 ) separates the underflow from the first cyclone separator ( 4 ') into water and sand.

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:
Apparatus (10) for separating entrained solids from a fluid flow (e.g., pond water), comprises an inner chamber (12) and an outer chamber (14) thus enabling two different separation operations to be performed. Specifically, the outer chamber (14) is used for cyclonic separation, with fluid flowing into the chamber from inlet (16) being swirled into a vortex to effect separation of relatively coarse solid particles from the fluid flow. Once subjected to cyclonic separation, fluid overflows weirs (18) into the inner chamber (12) for removal of relatively fine particles and other contaminants by filtration using resilient foam (40), before flowing through outlet (22).

A separator device (3) provided with a cyclone chamber (11, 79) for separating solid and/or liquid particles from a gas flow. The cyclone chamber (11, 79) has an upper wall (49) in which an outlet opening (15) is present, and a substantially rotationally symmetrical side wall (47, 81) in which an inlet opening (13) is present adjacent the upper wall (49). A discharge opening (17, 85) for the separated solid and/or liquid particles is present at a side (55, 83) of the cyclone chamber (11, 79) remote from the upper wall (49). According to the invention, a rotatable annular centrifugal unit (61, 87) is arranged in the cyclone chamber (11, 79) around the outlet opening (15) near the upper wall (49), by means of which unit a short-circuit flow running directly from the inlet opening (13) to the outlet opening (15) in the cyclone chamber (11, 79) is prevented. The efficiency of the separator device (3) is considerably improved thereby. In a first embodiment, the centrifugal unit (61) comprises a rotatable annular disc (65) positioned adjacent and parallel to the upper wall (49). In a second embodiment, the centrifugal unit (87) comprises a rotatable rim of blades (89) which is partly countersunk into a recess (95) in the upper wall (49). The separator device (3) can be used in a cyclone vacuum cleaner (1).

A cyclone dust collector wherein the interior of a cyclone body is divided into an upper space and a lower space by a partition member provided with a plurality of cylindrical filters, a suction port is so provided as to communicate with the lower space, a common discharge port is so provided as to communicate with the upper space, a collected dust recovery box is fixed to the lower end of the cyclone body, and a discharge blower is connected to the discharge port of the cyclone body. The dust collector is further provided with backwashing stop valves capable of opening and closing upper end portions of the filters and having backwashing nozzles, stop valve driving mechanisms adapted to open and close the stop valves, compressed air hoses connected to the backwashing nozzles of the stop valves, and backwashing electromagnetic valves for controlling the supply and cutoff of backwashing compressed air to the compressed air hoses. Each of the filters is able to be backwashed independently by supplying compressed air to the filters via the compressed air hoses, with the upper end portions of the filters closed by the stop valves.
摘要:
The invention relates to a process and apparatus for the separation of heavier from lighter fractions in aqueous slurries by means of centrifugal force. The slurry is made to spin in the separation chamber under the influence of the differential pressure generated between the inlet and outlet of a cyclone separation chamber (4). The differential pressure, which can amount to several bar, is generated by means of a pressure increasing stage in the form of a transport rotor device (20) which acts in conjunction with a stator arrangement (22); essentially this takes place immediately in front of the inlet of the slurry into the separation chamber (4). The rotor blades of the cyclone rotor device (10) as the rotor blades of the transport rotor device (20) can be mounted on the same rotary shaft (5) in order to induce additional rotary force into the slurry. The separation of floatable fractions in aqueous slurries is effected by the presence of micro gas bubbles introduced into the separation chamber (4). The separated floatable fractions can be removed from the gas bubbles to which they adhere by means of an anti-foaming device driven by the rotary shaft (5) of the transport rotor device (20).

The invention relates to a cyclone separator (1) with an elongated and essentially vertical housing (2) whose upper section (3) has a carrier gas/product inlet (4), a separator (5) and a discharge (7) for carrier gas/fine material. The lower section (9) of the housing has a coarse material discharge (11). To improve grading, it is proposed that the housing should be provided with a central built-in unit (12) extending substantially axially for separating the carrier gas/particle streams (23) associated with the cyclone and directed downwards in the peripheral region and upwards in the central region.

The filter construction comprises an inlet passage (1), a gas exhaust passage (2) and a filter (3) placed in the gas flow between said passages. As taught by the invention, it comprises a preseparation chamber (4) having a flow cross section substantially superior to that of the inlet passage and into the upper part of which the inlet passage opens and where the mass and the gas flow downward.
摘要:
A method and a device for reduction of any buildup of corrosion accumulations in a conduit circuit (1) for a continuous flow of a system liquid in a heating or cooling system, where a diverted flow (6) of the system liquid is diverted to a regeneration circuit (5) connectable to the conduit circuit. The diverted flow is, in a first regeneration step, subjected to (a) a pressure reduction which sets free any gases in the liquid, and (b) to centrifugal forces which separate any particles and gases from the liquid, and (c) to a turbulence which accomplishes a reduction in velocity of the diverted flow. The diverted flow is, in a second regeneration step, passed through a particle trap (9).
