Described are a system, device, and method for atmospheric water generation (AWG). A device can include a nucleation chamber defining a cyclonic pathway therewithin. A humid gas is communicated along the cyclonic pathway within the nucleation chamber. Electrospray nozzle(s) is(are) used to disperse a nucleation initiator into the inner volume of the nucleation chamber to cause nucleation of water droplets from water vapor in the humid gas. The water droplets can be condensed out of the air to form an aqueous product. The nucleation initiator can be electrically charged before dispersion within the nucleation chamber to increase nucleation of water droplets from the humid gas. The nucleation initiator can comprise a salt, a desiccant material, a hygroscopic material, an ionic liquid, water droplets, CaCl.sub.2, NaCl, LiCl, MgCl.sub.2, KCOOH, CH.sub.3COOK, or sulfates. Humid gas can be cooled to a temperature of between about 33 F. and about 75 F. before nucleation.

This invention relates to a process and apparatus for growing agricultural products with a reduced abundance of radioactive carbon-14 (.sup.14C) by employing centrifugal separation of atmospheric gases to selectively remove carbon dioxide (CO.sub.2) with .sup.14C. Agricultural products with reduced .sup.14C content can be grown in controlled environments with filtered atmospheric gases for the benefit of reducing harmful damage to human DNA that is unavoidable with our current food chain, due to the natural abundance of .sup.14C in atmospheric gases. Bilateral and unilateral compression helikon vortex apparatus provide efficient and economical removal of CO.sub.2 with .sup.14C from atmospheric gases with a single filtration pass, which is ideally suited for large scale agricultural production.

The present invention relates to methods for dewatering tailings and systems for performing same. In certain aspects, the invention relates to methods of producing a dewatered tailings residue or a stackable tailings residue, comprising subjecting tailings to hydrocyclonic separation to produce one or more partially dewatered underflows and a final water-rich overflow; separating the final water-rich overflow, by centrifuging, into a recovered water stream and a low-water residue; and mixing together the low-water residue and at least part of the one or more partially dewatered underflows to produce a dewatered tailings residue or a stackable tailings residue.

A ventilation module for a rail vehicle contains a housing having an air inlet, an air outlet, a dust discharge opening, a first cleaning station in an upper region of the housing, a cyclone separator which has a dust outlet and a cyclone air outlet. A second cleaning stage is disposed in a central region of the housing, which is arranged underneath the first cleaning stage such that air from the cyclone air outlet can reach the second cleaning stage. A dust discharge channel is connected to the dust outlet and is arranged in the central region. A dust discharge fan is set up to extract air and dust from the dust discharge channel and to remove the same through the dust discharge opening. A machine room fan is arranged in a lower region of the housing and is set up to extract air through the second cleaning station.

A handheld vacuum cleaner includes a dust cup assembly, a multi-cone separator and a motor assembly. The dust cup assembly includes a dust cup and a first filter structure. The multi-cone separator includes a number of conical cylinders arranged outside the first filter structure. Air inlet ends of the number of conical cylinders are in fluid communication with an air outlet end of the first filter structure. The motor assembly includes a motor arranged outside the first filter structure. The motor and the number of conical cylinders are located at a same end of the first filter structure. An air inlet end of the motor is in fluid communication with an air outlet end of the multi-cone separator. The number of the conical cylinders at least partially surround a peripheral side of the motor.

Various embodiments relate to devices and methods for treating a mixture of expansion gas and filling product foam in a beverage filling plant, comprising the steps of introducing the mixture of expansion gas and filling product foam into a closed separation container and extracting the expansion gas out of the closed separation container via suction.

An air filtration system comprising a plurality of sections configured to receive an incoming airstream is disclosed. In some embodiments, each section of the plurality of sections includes a first airstream receiving side (ASRS) and a second air stream exhaust side (ASES), and a plurality of cells each comprising a cyclonic cavity having a tangential inlet arranged to receive a portion of the airstream via the ASRS, and an axial outlet arranged to exhaust the portion of the airstream to the ASES. Each section is further configured with a cover that can be opened and closed, such that the closing of one or more respective covers of respective sections forces the airstream to flow through remaining sections having open covers as well as their respective cells, at a velocity greater than when such one or more respective covers are open.

A surface cleaning apparatus includes an air flow path, a cyclone bin assembly, and a suction motor. The air flow path extends from a dirty air inlet to a clean air outlet. The cyclone bin assembly is provided in the air flow path, and includes a cyclone chamber, a cyclone air inlet, a cyclone air outlet, a cyclone axis of rotation, and an axially extending cyclone chamber sidewall extending between first and second axially opposed ends. The cyclone chamber sidewall has first portion that is moveably mounted with respect to a second portion of the cyclone chamber sidewall between a closed position in which the first and second portions meet at a first juncture and a second juncture and an open position in which the cyclone chamber is opened. The first juncture extends at an angle to a plane that is transverse to the cyclone axis of rotation.

A cyclone type liquid-vapor separator includes a chamber including: an internal space wherein the treatment liquid introduced into the internal space is depressurized and evaporated; a vapor outlet formed on a top of the chamber and through which vapors generated through the evaporation is discharged; and a concentrated liquid outlet formed on a bottom of the chamber and through which the concentrated treatment liquid is discharged; an inlet part coupled to a side surface of the chamber in a tangent line direction of an inner peripheral surface of the chamber, the treatment liquid introduced into the chamber is turned in the form of vortexes along the inner peripheral surface of the chamber, and at least one partition wall disposed in an area between the inlet part and the vapor outlet of the internal space of the chamber and protruding from the inner peripheral wall of the chamber to prevent mist contained in the vapors from moving upwardly.
