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 particle separator assembly includes an airbox providing an outer tapered portion tapering from a first section having a first cross sectional area to a first opening having a second cross sectional area less than the first cross sectional area. The example assembly includes a flow diverter providing an inner tapered portion that tapers to a second opening. The example assembly includes an air filter housed by the airbox, the air filter is spaced from the second opening in a first direction, and the first opening is spaced from the second opening in a second direction opposite the first direction.

A system includes a cyclonic separator that separates a first production fluid into a lighter phase and a heavier phase and a pipe that transports the lighter phase from a first exit of the cyclonic separator to an annulus. The pipe includes an inlet fluidly connected to the cyclonic separator, a first outlet fluidly connected to the annulus, and a second outlet fluidly connected to the annulus. The system also includes a low pressure recombination zone that reintroduces the lighter phase to the heavier phase, thereby forming a second production fluid. The low pressure recombination zone transports the second production fluid to a well exit.

The partial or full dehydration of organic or inorganic matter containing water by induction of matter into a vacuum and processing matter through a specially designed acceleration channel is disclosed. The inducted matter accelerates in air from zero speed to sub-sonic speed to reach supersonic speed. As the material transitions the sound barrier, it is subject to acoustic shock waves and an instant negative pressure drop occurs. The sound waves disintegrate, disinfect the material and extract part or all moisture from any organic or inorganic material.

A negative-pressure dust collector system employs a dust separator device to separate the dust that is entrained in a stream of dust-laden air, exhausts the air stream to a vacuum-inducing machine, and discharge the separated dust downward into a bagger arrangement. The latter employs an open-bottom generally rigid hopper with a grid across its open bottom. A flexible dust collection bag is clamped onto an exterior of the hopper and hangs from the hopper. Under vacuum, the bag closes off the open bottom of said hopper. The grid has openings dimensioned so that dust in the container passes freely through the grid when the vacuum-inducing machine is shut off, but so that the bag may be sucked up against the grid, but not sucked into the open-bottom hopper when vacuum is applied. A flexible apron may be attached to the bottom of the hopper between the grid and the dust-collection bag.

A discharge arrangement (120) for a comminution reactor assembly (100). The discharge arrangement (120) comprises a main chamber (202) extending along a main axis (124). The main chamber has an inlet (121) arranged to be fluidly connected to a comminution reactor (110) and an outlet (122) arranged opposite from the inlet (121) along the main axis (124) and closeable by a common material take-out valve (204). The main chamber (202) is arranged to support a fluid-material stream (123) along a helical path about the main axis (124) from the inlet (121) towards the outlet (122). The discharge arrangement (120) further comprises an airduct (206) arranged extending into the main chamber (202) at an acute angle (a) with respect to the main axis (124). The airduct (206) comprises an aperture arranged facing the outlet (122). Thereby, a portion (125) of the fluid-material stream (123) changes direction from the helical fluid-material stream (123) about the main axis (124) from the inlet (121) towards the outlet (122) to a helical flow inside the airduct (206).
