Systems and methods are provided for mobile treatment of an exhaust stream. A treatment assembly including an inlet. A coupling is configured to releasably couple the inlet with an outlet of a stationary processing facility that produces an exhaust stream. The treatment assembly receives the exhaust stream in an input stream, treats at least one constituent of the input stream, and produces a treated exhaust. The treatment assembly is decouplable from the stationary processing facility and transportable to various locations.

Provided is a photocatalytic air-conditioning filter module, which is applied to a target space, including a first casing partition wall part having lattice-shaped spaces where photocatalytic balls are positioned, a second casing partition wall part connected to a rear end of the first casing partition wall part and having lattice-shaped spaces positioned to be staggered with respect to the lattice-shaped spaces of the first casing partition wall part, the photocatalytic balls accommodated in the lattice-shaped spaces of the first and second casing partition wall parts, a first cover configured to cover a front surface of the first casing partition wall part and prevent the photocatalytic balls from separating from the first casing partition wall part, and a second cover configured to cover a rear surface of the second casing partition wall part and prevent the photocatalytic balls from separating from the second casing partition wall part.

Provided is a pneumatic system for a vehicle, in particular a commercial vehicle. The system comprises a compressor, an air dryer cartridge, and a purge valve. The purge valve is protected by a filter. The filter is arranged in a housing and covers an inlet of an air channel formed in the housing which connects the inlet and the purge valve.

A frame-type air purifier includes a purifier housing and a front cover. The purifier housing includes a rear plate and a circumferential plate. The circumferential plate surrounds an outer periphery of the rear plate and forms a basin-shaped space. The basin-shaped space is divided into an open chamber and a close chamber. The open chamber includes a front opening. The close chamber includes an air inlet. The close chamber receives a purifier body. The front cover includes a front plate and a side frame. The side frame surrounds an outer periphery of the front plate and extends towards the rear plate. The front cover covers the front opening without contacting. The front plate and the circumferential plate are spaced by a longitudinal spacing. The side frame and the circumferential plate are spaced by a lateral spacing. The longitudinal spacing and the lateral spacing form an L-shaped air inlet channel.

Systems and methods are provided for mobile treatment of an exhaust stream. A treatment assembly including an inlet. A coupling is configured to releasably couple the inlet with an outlet of a stationary processing facility that produces an exhaust stream. The treatment assembly receives the exhaust stream in an input stream, treats at least one constituent of the input stream, and produces a treated exhaust. The treatment assembly is decouplable from the stationary processing facility and transportable to various locations.

A dust extraction unit is disclosed including a first and a second air filter removable and mountable within the dust extraction unit and a body defining an air flow path which passes through the first and the second air filters when the first and the second air filters are mounted within the body of the dust extraction unit. The body of the dust extraction unit comprises a first portion operable to receive the first air filter and a second portion operable to receive the second air filter. The first and second portions are connected by a hinge so that the first portion is moveable between a first configuration in which the first and second portion define an air flow path though the dust extraction unit and a second configuration which provides access to the portion of the dust extraction unit operable to receive the second air filter.

A dual-stage sand and gas separator for use within a wellbore of a fluid producing well is disclosed. During sand separation, fluid is ported into a vortex housing and across a vortex cup which imparts a vortex motion on the fluid to separate solids from the fluid. Some of the solids are filtered by a sand filter screen, while heavier solids are diverted down hole by a diverter plate. The fluid pass internally through the vortex cup into the gas separation housing. During the gas separation phase, a sump is created by the transfer tubing and gas is separated from the fluid and ported away from the tubing.

A liquid separator comprises a vessel with an inlet for a liquid/gas mixture. The vessel defines a space sealed at the top by means of a lid in which is situated an outlet to discharge treated gas. A shield is provided in the space extending around the outlet as of the lid, and a filter element provided within the shield. An outlet zone is defined between the shield and the filter element, wherein the outlet zone is in connection with the outlet. The shield comprises a bottom wall with at least one inlet opening and connection means for attaching the filter element onto the bottom wall. The connection means is configured such that the filter element, in a mounted condition, extends around the inlet opening as from the bottom wall, within a chamber defined by the shield, the lid and the bottom wall.

The present invention relates to a gas generator including a cylindrical filter in a housing including a gas discharge port, the housing including a plurality of independent protrusions or an annular protrusion protruding inwardly from an inner wall surface of the housing, the independent protrusions including an annular protruding wall surface, the annular protrusion including an annular tip surface, the cylindrical filter including a first annular end surface and a second annular end surface, a support member which includes an annular surface portion for supporting the cylindrical filter being arranged, the annular surface portion being an annular planar portion, or including an annular planar portion and a deformed portion for which all or a part of at least one of the inner peripheral portion and the outer peripheral portion of the annular planar portion is deformed, the support member being configured such that a part of the support member including an outer peripheral portion of the annular planar portion is arranged abutting against the annular protruding wall surface of the independent protrusions or the first annular protruding wall surface of the annular protrusion, and the second annular end surface of the cylindrical filter abutting against the annular planar portion of the support member, and the first annular end surface abutting against an inner wall surface of the housing.

A frame-type air purifier includes a purifier housing and a front cover. The purifier housing includes a rear plate and a circumferential plate. The circumferential plate surrounds an outer periphery of the rear plate and forms a basin-shaped space. The basin-shaped space is divided into an open chamber and a close chamber. The open chamber includes a front opening. The close chamber includes an air inlet. The close chamber receives a purifier body. The front cover includes a front plate and a side frame. The side frame surrounds an outer periphery of the front plate and extends towards the rear plate. The front cover covers the front opening without contacting. The front plate and the circumferential plate are spaced by a longitudinal spacing. The side frame and the circumferential plate are spaced by a lateral spacing. The longitudinal spacing and the lateral spacing form an L-shaped air inlet channel.
