A centrifugal separator includes a separation drum, a feed inlet, at least one heavy material outlet with a ring-shaped recess and at least one light material outlet. The feed inlet is located at the head of the separation drum. A feed accelerator is installed at the feed inlet. This feed accelerator cooperates with the proper form of the separation drum and the corresponding location of the material outlet to form a material differential rotation propulsion device. The material differential rotation propulsion device is capable of rotating the feed slurry material along with the separation drum in a slightly different rotation speed and forcing the processed materials to be discharged from separation drum via different outlets. The infeed flow rate is larger than or equal to the total sum of the outfeed flow rates of heavy and light materials so that the separation drum is full of materials during operation.

A method for washing platelets includes introducing anticoagulant into a platelet product container, drawing re-anticoagulated platelet product from the platelet product container, and introducing it into a centrifuge bowl. The centrifuge bowl separates the platelets from the supernatant in which they are suspended. The method then washes the platelets by introducing wash solution into the centrifuge bowl. As the wash solution is introduced into the bowl, it displaces the supernatant from the bowl and into a waste container. The method then introduces platelet additive solution into the centrifuge bowl, which displaces the wash solution from the centrifuge bowl and into the waste container and further wash the platelets. The method then repeatedly accelerates and decelerates the centrifuge bowl to resuspend the platelets in the platelet additive solution.

A centrifugal filtering device includes a centrifugal drum and a rotary filter. The centrifugal drum has a receiving space for accommodating the source fluid. The rotary filter rotatably mounted in the receiving space includes a filter body and a filtrate discharge pipe. The filter body includes a filter cartridge defining a filtrate-collecting space. The filtrate discharge pipe connecting the filter body is communicative in space with the filtrate-collecting space. By rotating at least one of the centrifugal drum and the rotary filter, the source fluid is driven to generate a vortex by a centrifugal force. The centrifugal force drives the source fluid to form a heavy-phase fluid hitting the centrifugal drum and a light-phase fluid approaching the filter cartridge. The light-phase fluid passes the filter cartridge and then reaches the filtrate-collecting space as a filtrate, and the filtrate is exhausted via the filtrate discharge pipe of the centrifugal filtering device.

Method and system for recovering weighting material and making a weighted drilling fluid

Номер: US20170014836A1
Автор: Russell FISHER
Принадлежит: KAYDEN INDUSTRIES LP

A horizontal centrifuge, method and system of use, recovers weighting materials from a returned drilling fluid slurry. A clean fluid is delivered, through a clean fluid pipe arranged axially at the hub, to solids discharge ports. The clean fluid is directed radially and circumferentially outwardly at the discharge ports for mixing homogeneously with the recovered weighting materials from forming a reconstituted weighted drilling mud. The reconstituted weighted drilling mud can then be delivered to a rig mud tank for use in a drilling operation. In the system, a drilling fluid and low gravity solids, which are separated from the weighting materials in the horizontal centrifuge, being a first centrifuge, are directed to a second centrifuge which is capable of removing the low gravity solids, thereby producing a clean fluid. The clean fluid is recycled to the first centrifuge for delivery through the clean fluid pipe.

The invention relates to a centrifugal separator comprising a casing which delimits and seals off a space in which a rotor is arranged. The rotor forms a separation space which is sealed or isolated from the space, and in which separation space centrifugal separation of a higher density and a lower density component from a fluid takes place. An inlet extends into the rotor for introducing fluid to the separation space, and a first outlet extends from the rotor for discharge of a component separated from the fluid. The space is connected to a pump device which is arranged to remove gas, thereby maintaining negative pressure in said space. The rotor comprises at least one second outlet extending from the separation space to the space for discharge of at least one higher density component separated from the fluid. The invention also relates to a method in such a centrifugal separator. 1. A centrifugal separator comprising a casing which delimits a space which is sealed relative to the surroundings of the casing and in which a rotor is arranged for rotation , which rotor forms within itself a separation space , and in which separation space centrifugal separation of at least one higher density component and at least one lower density component from a fluid takes place during operation , into which rotor at least one inlet extends for introducing said fluid to the separation space , and from which rotor at least one first outlet extends for discharge of at least one component separated from the fluid during operation , wherein the space is connected to a pump device which is arranged to remove gas from the space during operation , thereby maintaining negative pressure in said space , and wherein the rotor comprises at least one second outlet extending from a portion of the separation space to the space for discharge of at least one higher density component separated from the fluid during operation;the at least one second outlet being configured to at least partially seal ...

A centrifugal separator for separating a fluid mixture into components, including a non-rotating part, a rotor which is attached to a shaft which is rotatably supported in the non-rotating part around a rotational axis, which rotor forms within itself a separation space delimited by a rotor wall. The separator includes an inlet extending into the rotor for supply of a fluid mixture to be separated in the separation space, at least one sensor measuring unbalance conditions in the frame; a level determining arrangement including two or more space defining elements of arbitrary form arranged on the interior surface of, or close to, the rotor wall, where each space defining element defines a space which communicates with the separation space or another of the space defining elements through at least one inlet opening arranged at a certain radius from the rotational axis and not outside that radius and where that certain radii of the space defining elements are different. Methods for determining when a predetermined amount of heavy phase fluid (purification) or sludge (clarification) has been separated are also disclosed. The separator and methods make it possible to determine when the level of separated heavy phase fluid or sludge is high enough for emptying or discharge of the separator. 1. A centrifugal separator for separating a fluid mixture into components , comprising:a non-rotating part;a rotor, said rotor being attached to a shaft rotatably supported in the non-rotating part around a rotational axis, the rotor forming within itself a separation space delimited by a rotor wall;an inlet extending into the rotor for supply of a fluid mixture to be separated in the separation space;at least one sensor measuring unbalance conditions in the frame; anda heavy phase level determining arrangement comprising two or more space defining elements of arbitrary form arranged on an interior surface of, or close to, the rotor wall,wherein each space defining element defines a ...
