A gas-liquid separator includes an inlet pipe through which a gas-liquid two-phase fluid flows and a swirling flow generating ribbon disposed within the inlet pipe to swirl the gas-liquid two-phase fluid along an inner surface of the inlet pipe, wherein the inner surface of the inlet pipe includes a first step surface at a location downstream of a flow direction of the gas-liquid two-phase fluid from the swirling flow generating ribbon, the first step surface increasing an inner diameter of the inlet pipe downward thereof.

The disclosure relates to an axial-flow centrifugal separator for separating particles from a dispersion, in particular a suspension, which contains the particles and a fluid, the separator including a hollow cylindrical pipe section for conducting the dispersion in a conducting direction. An inner wall of the hollow cylindrical pipe section may have an internal thread, the lead angle of which increases in the conducting direction.

A cyclone separator wherein the tapered tip of the conical hollow body faces downwards. The air separator has at least one immersion tube which abuts the conical wall of the conical hollow body and which protrudes upwards within the conical hollow body, the conical hollow body tapered tip which faces downwards being connected to an outlet for fine material. The first cylindrical hollow body is equipped with a rotating rod basket which is enclosed by a static circular conveyor trough for coarse material, the conveyor trough resting against the lower outer circumference without contacting same. The conveyor trough for coarse material is connected to an outlet out of the cylindrical hollow body, and the volume enclosed by the rod basket is fluidically connected to the conical hollow body.

An ultra violet air disinfectant machine 100 that includes a cyclone separator 120 configured and arranged for effecting a spiral vortex flow of air through a disinfection chamber 129 about a longitudinal axis x operable for inertial concentration of microbes in the spiral vortex flow of air proximate a sidewall 122s of the cyclone separator 120, and a source of germicidal ultraviolet radiation 140 positioned external to the disinfection chamber 129 for emitting germicidal ultraviolet radiation towards and into the disinfection chamber 129.

In an FCC apparatus and process gas and catalyst exit from a riser, are disengaged from each other and the catalyst is stripped. Product gases are evacuated from catalyst that can over crack the product gases to other undesired products. A baffle in or above the stripping section can direct product gases into a passage that evacuates the product gases to product recovery in isolation from the catalyst.

A multi-cyclonic dust filter device comprises a dust collection chamber for collecting dust, a cyclonic chamber providing a gas to-be-filtered out dust to enter and forming a first cyclone to enter into the dust collection chamber, and a deflector component disposed between the dust collection chamber and the cyclonic chamber; the deflector component comprises a first deflector tube for receiving the gas to-be-filtered out dust refluxed from the dust collection chamber and forming a second cyclone, and a second deflector tube disposed in a same axial direction as the first deflector tube and separately disposed by an airflow convergence interval, the first deflector tube is provided with at least one dust filter hole for discharging the dust in the second cyclone, and the second deflector tube combines the first cyclone and the second cyclone through the airflow convergence interval to form a third cyclone for discharging.

A centrifugal gas-liquid separator wherein a tubular casing houses a central tubular duct, which is provided with a first free end and with a second end that communicates with a gas-outlet duct and carries a transversal annulus-shaped plate having a perimetral edge that faces the inner wall of the tubular body to define an annular gap. The plate divides the space inside the tubular casing into a first chamber and into a second chamber that communicate with each other through the annular gap. A liquid-outlet duct communicates with the second chamber and a liquid-phase/gas-phase inlet duct extends tangentially from the tubular casing and discharges into the first chamber through an inlet nozzle. A regulation device is provided, which is designed to modify the section of the inlet nozzle in order to modify the rate of entry of the liquid phase and gas phase into the first chamber and to adapt the operation of the centrifugal gas-liquid separator following variations of flow rate.

A turbine engine having an inducer assembly. The inducer assembly includes a centrifugal separator fluidly coupled to an inducer with an inducer inlet and an inducer outlet. The centrifugal separator includes a body, an angular velocity increaser to form a concentrated-particle stream and a reduced-particle stream, a flow splitter, and an exit conduit fluidly coupled to the body to receive the reduced-particle stream and define a separator outlet.

A turbine engine having a bypass fluid conduit coupled to the turbine section includes at least one particle separator located within the bypass fluid conduit to separate particles from a bypass fluid stream prior to the bypass stream reaching the turbine section for cooling. A centrifugal separator for removing particles from a fluid stream includes an angular velocity increaser, a particle outlet, an angular velocity decreaser downstream of the angular velocity increaser, and a bend provided between the angular velocity increaser and the angular velocity decreaser.
