摘要： A centrifugal separator for cleaning gas containing contaminants includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas to be cleaned, a rotating member including a plurality of separation members arranged in said separation space and being arranged to rotate around an axis of rotation, a gas outlet configured to permit discharge of cleaned gas and including an outlet opening through a wall of the stationary casing, a drainage outlet configured to permit discharge of liquid impurities separated from the gas to be cleaned, and a drive member, for rotating the rotating member. The centrifugal separator further includes a control unit configured to control the drive member to rotate the rotating member at a first speed during a separation phase and at a second speed, which is higher than the first speed, during a cleaning phase to remove clogging on or between said separation members, wherein the cleaning phase is shorter in time than the separation phase.

摘要： An oil separator that separates mist oil from processing-target gas containing mist liquid includes a plurality of separation disks. The plurality of separation disks rotate around an axis, and are stacked and spaced in an axial direction. The separation disk includes an inner peripheral part and an outer peripheral part. The inner peripheral part forms a surface of a frustum of a hypothetical cone or pyramid coaxial with the separation disk, and is inclined with respect to a radial direction toward one side in an axial direction. The outer peripheral part forms a surface of a frustum of a hypothetical cone or pyramid coaxial with the separation disk, and continuously extends outward from an outer peripheral edge of the inner peripheral part. The outer peripheral part is inclined with respect to the radial direction toward another side in the axial direction.

摘要： A system for analyzing particles in an air stream includes a first heater element configured to deflect particles in an interior region of the air stream towards a peripheral wall of an air channel encompassing the air stream, a second heater element controllable to deflect the particles in a first lateral direction along the peripheral wall, and a third heater element controllable to deflect the particles in a second lateral direction along the peripheral wall. Thermal gradients in the air channel generated by the heater elements may thermophoretically force particles towards the peripheral wall in a direction perpendicular to the air stream to allow thermophoretic forcing and scanning of particles in either the first lateral direction or the second lateral direction along the peripheral wall and onto a surface of a particle detector. Systems and methods for scanning particles with thermophoretic forces are disclosed.

摘要： The present invention is a centrifuge to be used for removing ice particles from the air fed to a gas turbine system. In an embodiment, the centrifuge is comprised of three ducts defining an air-path which comprises of two bends greater than 90 degrees. In an embodiment, the first two ducts extend past the bends to provide a dead air zone to trap ice particles which have been introduced by cooling air containing moisture. The dead air zones are further provided with revolving doors which remove the ice particles from the system. In an embodiment, the centrifuge receives cold air from the compander and removes ice particles before exhausting the cold air to a gas turbine electric generator, such that the blades of the gas turbine generator are not damaged by the ice particles.

摘要： An internal combustion engine and centrifugal separator assembly separates contaminants from crankcase gas. A crankcase is connected to the centrifugal separator including a centrifugal rotor. A rotor housing delimits a separation space in which the centrifugal rotor is arranged to rotate. A gas inlet conducts crankcase gas to a central part of the centrifugal rotor. A gas outlet communicates with a part of the separation space surrounding the centrifugal rotor and to conduct cleaned crankcase gas out of the separation space. A particle outlet communicates with the part of the separation space. The particle outlet is connected to a collector for the separated particles. The collector is configured to communicate with the gas inlet via a connection to provide a pressure difference between the particle outlet and the collector. The separated particles are drawn out of the particle outlet and into the collector during operation of the centrifugal separator.

摘要： A system for separating an air-liquid mixture in a low gravity environment is disclosed having a high speed separator to initially process the air-liquid mixture. A second, low-speed separator has its inlet connected to the liquid discharge outlet of the high speed separator in order to remove the entrained air bubbles from the liquid discharge of the high speed separator. The low speed separator has a stationary housing enclosing a rotating, paddle-type separator. The housing defines a liquid collector portion which communicates directly with a liquid discharge outlet. Air removed by the low speed separator may be vented to the ambient atmosphere, or may be returned to the air-liquid mixture inlet of the high speed separator.
