A uniflow cyclone for a hand vacuum cleaner has a dirt chamber that is external to the cyclone chamber and vortex finder, which has a solid portion that is spaced from and faces a dirt outlet of the cyclone chamber and a porous section that is angularly spaced around the cyclone axis of rotation of the cyclone from the solid portion.

A cyclone for a hand vacuum cleaner has an outlet port that is sized to produce an annular flow band in the cyclone which extends radially inwardly to overlap the solid sidewall of the vortex finder.

A dust cup assembly (100) and a handheld cleaner (1000) having the same are provided. The dust cup assembly (100) includes: a cup casing (1); a device housing (2) configured as a tube shape and disposed in the cup casing (1), wherein an outer end face of the device housing (2) at an axial side thereof abuts against or extends beyond a partial inner surface of the cup casing (1), and a dust removal chamber (A1) is defined between an inner surface of the cup casing (1) and an outer peripheral surface of the device housing (2) and surrounds the device housing (2) along a circumferential direction of the device housing (2); and a negative pressure device (3) located within the device housing (2) and enabling dusty air to enter the dust removal chamber (A1) for dust and air separation.

Disclosed herein are phase separator devices, and related methods of fabrication and use. The disclosure provides improved phase separator devices for phase separation of input feeds, and systems/methods for utilizing and fabricating the devices. The disclosure provides phase separator devices utilizing inertial separation and porous media extraction for the phase separation of two-phase input feeds (e.g., to separate an input feed of a two-phase mixture to a first phase output (e.g., to a liquid output flow) and to a second phase output (e.g., to a gas output flow)). The device can separate a mixed fluid flow of both liquid and gases. The liquid and gas can include liquid and vapor phases of the same chemical/constituent (e.g., ammonia), or may include liquid and gases of two different constituents (e.g., liquid water and air). The phase separator devices can be utilized at standard gravity to micro-gravity to zero gravity environments.

The present disclosure relates to a gas cooling-scrubbing apparatus and an associated method. There is provided a gas cooling-scrubbing apparatus, comprising: a cyclone jet scrubbing unit, a spray scrubbing unit, a filtering spray unit, and a coalescing dehydration unit, wherein the cyclone jet scrubbing unit comprises a cyclone jet scrubbing monopipe (2), a cyclone jet cooling water pipe (15), a cyclone jet pipe plate (14) and a cyclone jet overflow pipe (13); wherein the spray scrubbing unit comprises a spray filtering pipe (3), a spray pipe plate (11), a spray overflow pipe (12), a scrubbing nozzle (9) and a scrubbing nozzle water pipe (10); wherein the filtering spray unit comprises a filtering bed (4), a spray head (7) and a spray water pipe (8); and wherein the coalescing dehydration unit comprises a coalescing bed (5). There is also provided a gas cooling-scrubbing method.

A separator tank and a gas compressor having a separator tank are provided. The separator tank includes a tank body defining an inner volume, a tank inlet pipe providing fluid communication with the inner volume of the tank body, wherein the tank inlet pipe tangentially penetrates the tank body and is oriented to direct fluid entering the tank body in a spiral fluid flow pathway, and a sump tube positioned to collect fluid flowing within the tank body, the sump tube comprising a vertically oriented opening oriented to align and capture fluid flowing along the spiral fluid flow pathway.

A method of separating a fluid includes adding a fluid to a canister of a fluid separator. The canister includes first and second barriers disposed concentrically within the canister that define a first and second annulus within the canister, and a canister rotor having a first magnet associated therewith. The method includes rotating an induction base rotor disposed within an induction base. The induction base rotor includes a second magnet. The canister rotor and the induction base rotor are magnetically coupled and rotating the induction base rotor causes the canister rotor to rotate. The method further includes forming a vortex in the fluid via the rotation of the canister rotor, and the vortex causes the fluid to separate into a first component and a second component.

A cyclone separator for a powder recovery device of a powder coating system includes an inlet region with an inlet for a mixed flow of powder/air, a separation region adjoining the lower end region of the inlet region for the centrifugal separation of at least a portion of the powder contained in the mixed flow, and a powder collecting region connected or connectable to the lower end region of the separation region for collecting the powder separated in the separation region. The powder collecting region is shiftable relative to the separation region between a first position in which the powder collecting region is aligned in flush connection with the lower end region of the separation region and a second position in which the powder collecting region is not aligned in flush connection with the lower end region of the separation region.

A separator tank and a gas compressor having a separator tank are provided. The separator tank includes a tank body defining an inner volume, a tank inlet pipe providing fluid communication with the inner volume of the tank body, wherein the tank inlet pipe tangentially penetrates the tank body and is oriented to direct fluid entering the tank body in a spiral fluid flow pathway, and a sump tube positioned to collect fluid flowing within the tank body, the sump tube comprising a vertically oriented opening oriented to align and capture fluid flowing along the spiral fluid flow pathway.

A filter assembly including a filter screen (27) comprising a band (27′) of porous material extending between two axially aligned opposing ends (38, 38′) and defining a cylindrical periphery (29), wherein the ends (38, 38′) are each secured to a dynamic tensioning mechanism (46) that permits the ends (38, 38′) to move bi-directionally relative to one another about the periphery (29) of the filter screen (27).
