Embodiments of the disclosure pertain to an apparatus comprising a phase separator configured to separate a mixture comprising (i) water containing NaCl and (ii) oil and/or gas into separate streams comprising the water, the oil (when oil is in the mixture), and the gas (when gas is in the mixture), an electrochemical membrane separation cell configured to separate sodium and chloride ions in the water stream to form a stream comprising a first sodium hydroxide solution and a stream comprising (i) hydrochloric acid and/or (ii) chlorine gas, a compressor configured to compress a gas containing CO.sub.2, a spray dryer configured to mix aqueous NaOH and the compressed gas to form sodium carbonate, and a cyclone separator configured separate the sodium carbonate from any excess components of the aqueous NaOH and/or the compressed gas.

Provided is a cardboard conversion line including a wet cyclone dust collector for removing dust laden air from the conversion line. The wet cyclone dust collector has a swirl chamber in which air containing particles swirls in a rotational direction and a plurality of circumferentially spaced nozzles located within the swirl chamber to direct a spray of fluid within the swirl chamber in the rotational direction to wet the air containing particles, and the wetted particles are separated from the air in the swirl chamber. In this way, a system may be provided to clean high volumes of air containing particles without having to provide an explosion vent and without having to provide additional fans, motors, and compressed air.

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 vacuum cleaner including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; and a rotatable shell provided at a lower side of and surrounding the first cyclone so as to define a first storage section configured to collect foreign matter and dust filtered by the first cyclone between the rotatable shell and the outer case, wherein the rotatable shell includes a skirt having a plurality of steps arranged along a circumference of the rotatable shell.

A vacuum cleaner, including a cleaner body; and a dust collector provided in the cleaner body, wherein the dust collector includes a first cyclone provided within an outer case to filter foreign matter and dust from air introduced into the dust collector; a second cyclone accommodated within the first cyclone to separate fine dust from the air introduced into the first cyclone; a screw provided at a lower side of and surrounding the first cyclone, and having at least one vane spirally extended along a flow direction of the air introduced into the outer case to induce the inflow of foreign matter and dust filtered by the first cyclone into a first storage section.

A centrifugal liquid separating system broadly comprises an insert cartridge including a housing, an inlet, one or more flow guides, a stator, a compression nozzle, an expansion nozzle, and an outlet. The flow guides guide liquid flowing into the inlet past the stator into the compression nozzle. The stator induces a rotational vortex into the liquid flow. Liquid with heavier particles in the liquid flow is urged to the outside of the rotational vortex. Liquid with lighter particles and cleaner liquid is urged to the inside of the rotational vortex. The compression nozzle and the expansion nozzle are aligned to cooperatively form an annular liquid channel. The liquid with the heavier particles flows through the annular liquid channel and the liquid with the lighter particles and the cleaner liquid flows to the expansion nozzle to the outlet.

A dust separator including a top member having a top member having an inlet port arranged to supply dust-laden air and an outlet port arranged to remove clean air, the top member having a lower portion configured as a lip and having a radius which equals diameter of the inlet port, and a dust separator plate, housed within the lip, having a passage with at least one opening arranged to remove the dust from within the top member.

A system and methods for separating liquids, aerosols, and solids from a flowing gas stream whereby gas flows through a helical path formed in a separator element. Partially separated gas exits the bottom of the separator element at a generally conical cavity. Clean gas exits through an inner tube that is axially aligned beneath the helical path. Separated materials exit through an annular space between the inner tube and an outer tube. Separation occurs in the helical channels which include radially diverging walls to provide an aerodynamically efficient flow, in a region of high swirl created in a generally conical cavity beneath the separator element. In higher liquid-loading or slug flow conditions, a passageway may be formed in the separator element for recirculating a portion of the gas flow exiting from the bottom of the outer tube, into an axial passage in the helical separator, and exiting from the bottom of the helical separator near the vertex of the conical cavity.
