Disclosed is a device for cooling particulate materials or particles, in particular granulates of polymeric materials, having an outer container with an, in particular frustoconical, outer shell surface and an inner container, which is arranged at least in sections in the interior of the outer container, with an, in particular frustoconical, inner shell surface, wherein an intermediate space is formed between the outer shell surface and the inner shell surface, wherein an inlet equipment for introducing a gas flow as well as the particles into the intermediate space is provided in an inlet-side initial region of the device, and wherein an outlet opening for the particles is provided in an outlet-side end region of the device opposite the inlet equipment, wherein the inlet equipment is so arranged and/or designed that the gas flow as well as the particles can be introduced substantially tangentially into the intermediate space.

A hydrogen-water separator for a fuel cell includes an upper separation chamber having a first cylindrical sidewall defining an inlet port and a lower collection chamber configured to collect separated water. The collection chamber has a bottom and a second cylindrical sidewall defining a drain port disposed above the bottom. A divider is disposed between the separation chamber and the collection chamber. The divider spans the first cylindrical sidewall and defining one or more openings. An outlet tube is arranged vertically in the separation chamber and having an entrance that is disposed above the divider and below the inlet port.

A sand trap for oil and gas extraction includes a cyclonic flow section having a longitudinal axis, an inlet for receiving a high-pressure fluid stream with particulates, an upper portion, a choke area, and a funnel portion narrowing from the upper portion to the choke area. The inlet has an axis generally perpendicular but askew to the longitudinal axis. A vortex finder extends downwardly from a cap and defines a passageway coaxial with the longitudinal axis for fluid to exit. A spherical accumulator extends downwardly from the cyclonic flow section and has a center axis coaxial with the longitudinal axis. Upper and lower ends of the spherical accumulator each have an opening centered along the longitudinal axis, and the spherical accumulator is unobstructed from the upper opening to the lower opening for the particulates to pass unimpeded and accumulate in the accumulator.

A separator for separating solid particles from a processing gas stream that has been fed repeatedly through a work machine, wherein the separator includes a processing gas inlet through which particle-laden processing gas emitted from the work machine is fed into the separator, and a filterless separator element to reduce the particle content of the processing gas and a processing gas outlet to discharge the processing gas with its reduced particle content to the work machine, the separator including a secondary stream filter, which filters a smaller portion of the processing gas, and a secondary outlet, connected thereto, which ejects the filtered secondary stream of processing gas.

Described embodiments generally relate to a hydrocyclone for isolating particles within a fluid. The hydrocyclone comprises an upper conical section defining at least one inlet to receive the fluid, a vortex finder extending into the upper conical section, and an overflow port fluidly connected to the vortex finder and configured to expel a portion of the fluid out of the upper conical section; and a lower conical section defining an underflow port to expel the remaining fluid out of the lower conical section, the lower conical section being fluidly connected to the upper conical section to define a single hollow volume. The shape of the hydrocyclone causes particles smaller than a predetermined size to be isolated by expelling the particles from the overflow port.
