An actuator for a separator for separating contaminants from a fluid stream which includes entrained contaminants. The actuator is arranged to move along an actuator axis to adjust an open cross-sectional area of at least one aperture of the separator, and comprises a flexible diaphragm, and a support assembly for the flexible diaphragm. The support assembly is movable along the actuator axis carrying the flexible diaphragm and has an upper support member mounted on a lower support member. A portion of the flexible diaphragm is located between the upper and lower support members. The lower support member comprises an axially extending support portion coupled to a radially extending support portion. The upper support member comprises a diaphragm anti-inversion feature coupled to a radially extending support portion. The diaphragm anti-inversion feature extends such that it axially overlaps at least part of the axially extending support portion of the lower support member.

A vacuum cleaner comprising a dirty air intake and a cyclonic separating apparatus connected in series. The cyclonic separating apparatus comprises a plurality of cyclonic separators connected in parallel. The vacuum cleaner further comprises a bleed valve provided upstream of the plurality of cyclonic separators. The bleed valve opens to admit bled air into the plurality of cyclonic separators in response to a drop in pressure in the vacuum cleaner. The bleed valve is also connected to the inlets of the plurality of cyclonic separators via a common plenum.

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.

A dust collecting system for single crystal growth system includes an air compressor, a dust collecting device, a first inert gas source, a rotary pump and a scrubber. The air compressor is fluidly connected to an exit pipe of the single crystal growth system. The exit pipe is used to exhaust unstable dust from the single crystal growth system. The dust collecting device is fluidly connecting to the exit pipe to collect the dust oxide. The first inert gas source is fluidly connected to the exit pipe to blow a first inert gas into the exit pipe to compel the dust oxide toward the dust collecting device. The rotary pump is fluidly connected to the dust collecting device. The scrubber is fluidly connected to the rotary pump. The rotary pump transports the residual dust oxide toward the scrubber. The present disclosure further provides a method for collecting dust.

An air conditioning device includes a body comprising an inlet plenum portion to receive input air including vapor molecules, a spray chamber portion to receive the input air, the received input air being rigorously mixed within the spray chamber, a sprayer portion to charge a liquid droplet and to release the charged liquid droplet into the rigorously mixed air to cause the charged liquid droplet to attract a vapor molecule, such that the vapor molecule attaches to the charged liquid droplet and separates from the input air, a separation chamber portion to cause the liquid droplet with the attached vapor molecule to separate from the rigorously mixed air and to condense and collect as liquid within an outlet plenum, and an air outlet portion to direct output air from the air conditioning device, a first humidity of the output air being less than a second humidity of the input air.

A device for separating and extracting suspended solids and particles from a fluid is shown. The device can include a hydro-cyclonic process unit, a variable geometry vortex process unit, a reverse coalescence and flocculation process unit and a fixed geometry vortices separator process unit. The fluid to be treated can enter the device through a fluid inlet and travel and recirculate through the several process units. The process units can collectively induce vorticose separation of the fluid and separate suspended solids and particles within the fluid. The suspended solids and particles can then be extracted from the device via one or more extraction fluid outlets. After the desired amount of suspended solids and particles has been removed, the processed fluid can be discharged from the device.

An inertial vortex particle scrubber includes a housing having an inlet guide, twin vortex chambers and an outlet. A particle-laden air stream is accelerated as it passes through the inlet guide into the twin vortex chambers where particles are displaced by centrifugal forces toward a wall of the twin vortex chambers. A relatively particle-free air stream is then discharged from the outlet.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A water treatment device including a first hydrocyclone and a biocidal fluid injector is described. The first hydrocyclone has an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet. The biocidal fluid injector is configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water. The biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.

A surface cleaning apparatus such as an extractor has a liquid delivery system, a separator, a collection chamber in communication a the separated element outlet of the separator, and a separated liquid collection container downstream from the collection chamber.
