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.

A separator apparatus is described for separating liquids and solids from a gas. The separator apparatus includes a reverse flow cyclone comprising a cylindrical section, a conical section, and a top, the cylindrical section having a feed inlet, the top having a gas outlet, and the conical section having a reject outlet at the bottom thereof. An axial cyclone is disposed in the cylindrical section, the axial cyclone oriented with a first end located proximate to the top of the apparatus and a second end opposite the first end, the axial cyclone having a tapered entrance fixture at the second end thereof and having a wall with a plurality of openings located between the first end of the axial cyclone and a midpoint of the axial cyclone. A drain plate is coupled to the cylindrical section below the openings of the axial cyclone.

Provided is a chiller and system that may be utilized in a supercritical fluid chromatography method, wherein a non-polar solvent may replace a portion or all of a polar solvent for the purpose of separating or extracting desired sample molecules from a combined sample/solvent stream. The system may reduce the amount of polar solvent necessary for chromatographic separation and/or extraction of desired samples. The system may incorporate a supercritical fluid chiller, a supercritical fluid pressure-equalizing vessel and a supercritical fluid cyclonic separator. The supercritical fluid chiller allows for efficient and consistent pumping of liquid-phase gases employing off-the-shelf HPLC pumps. The pressure equalizing vessel allows the use of off-the-shelf HPLC column cartridges. The system may further incorporate the use of one or more disposable cartridges containing silica gel or other suitable medium. The system may also utilize an open loop cooling circuit using fluids with a positive Joule-Thompson coefficient.

An autonomous vacuum cleaner operable to navigate about a surrounding environment to perform a surface cleaning operation without continuous human input. The vacuum cleaner includes a suction nozzle and a suction motor and a fan assembly operable to generate an airflow through the vacuum cleaner from the suction nozzle through a debris separator to a clean air exhaust. The suction motor and the fan assembly having an axis of rotation and a fan of the fan assembly rotatable about the axis of rotation. The axis of rotation is orientated horizontally. The debris separator includes a cyclonic separator operable to separate debris from the airflow and the cyclonic separator includes a cylindrical wall along a longitudinal axis, the longitudinal axis of the cyclonic separator being orientated horizontally.

A particle separator (1) for fluids has an outlet chamber (3) arranged within an inlet chamber (2) and is fluidically connected to same, wherein the inlet chamber (2) has a curved guide surface (5) extending around a main axis (4) running transverse to the main flow direction in the inlet chamber (2) for the fluid flowing into the inlet chamber (2) via an inlet channel (6). Particles can be filtered out of the fluid largely independently of the orientation of the particle separator relative to the gravitational vector and without entering the outlet channel even after separation of the fluid flow and possible positional change. The outlet chamber (3) is closed with respect to the inlet chamber (2) transverse to the direction of the main axis (4) and open in the direction of the main axis (4), and has an outlet channel (7) that extends through the inlet chamber (2).
