The present invention addresses to a third stage system with self-bleeding by means of the use of an internally or externally installed ejector with application in all multicyclone systems operating at positive pressure, whether for application in particulate abatement or protection systems of turbo-expanders or in industrial units that involve the need of recovering solid products carried by the process gas, aiming at eliminating the need for any additional separation systems using cyclones or filters to carry out the bleeding of the cyclone legs.

An upright extractor has an upright section moveably mounted to a surface cleaning head. The upright section has a wand and hose assembly and a liquid separator. The liquid separator comprises a solid collection chamber that is separated from a liquid collection chamber by a porous divider. The upright extractor is operable in a floor cleaning mode in which the handle is a driving handle of the upright extractor. The upright extractor is also operable in an above floor cleaning mode in which the inlet end of the wand is disconnected from fluid flow communication with the surface cleaning head dirty fluid inlet and an above floor air flow path extends from the inlet end of the wand to the clean air outlet and the liquid separator and the suction motor are provided in the above floor cleaning air flow path.

Systems and methods for removing contaminants from surfaces of a solid material using a flow of compressible fluid to draw incompressible fluid through pathways between fragments of the solid material. At least one method includes introducing solid material into a processing chamber, concurrently directing compressible fluid and incompressible fluid into the processing chamber via the inlet fluid distribution manifold, and operating a vacuum pump to maintain a pressure at a discharge outlet of the processing chamber sufficient to promote the compressible and incompressible fluids each achieving a velocity of at least 10 meters per second within the processing chamber.

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.

An air conditioning device includes an inlet plenum to receive input air, a sprayer to charge at least one of a plurality of liquid droplets generating at least one charged liquid droplet and to release the charged liquid droplet into air rotating vortex, moving the input air within a spray chamber, to cause the charged liquid droplet to attract and attach a vapor molecule of the input air separating the molecule from the input air, a separation chamber to cause the liquid droplet with the attached vapor molecule to separate from the vortex to condense and collect as liquid, and an air outlet to direct, away from the air conditioning device, output air including air remaining following the separation, from the vortex, of the liquid droplet with the attached vapor molecule, where a first humidity of the output air is less than a second humidity of the input air.

A hand vacuum cleaner comprises a cyclone comprising a front end having a cyclone air inlet, a rear end having a cyclone air outlet and a cyclone axis of rotation extending between the front end and the rear end of the cyclone. A conical pre-motor filter is positioned rearward of the cyclone. The pre-motor filter has a front end that faces that faces towards the cyclone air outlet. A suction motor is positioned rearward of the pre-motor filter. The suction motor has an inlet end that faces towards a rear end of the pre-motor filter. A handle is provided at the rear end of the hand vacuum cleaner and is positioned rearward of the suction motor. The handle has an energy storage member housing, The cyclone axis of rotation and the suction motor axis of rotation are parallel, and the handle axis extends at an angle to the cyclone axis of rotation and the suction motor axis of rotation.

A suction apparatus includes a housing, at least one cyclone chamber, a collection container configured to as to be releasably connectable to the housing, and having a filter element. The suction apparatus further includes at least one positioning device within the cyclone chamber and configured for positioning at least one collection element within the cyclone chamber.

Disclosed are a base station and a cleaning equipment. The base station includes: a first box defined with a sewage inlet for solid-liquid mixed garbage to enter the first box; a second box communicated with the first box, for receiving liquid garbage from the first box; a cyclone separator communicated with the first box; and a fan communicated with the cyclone separator, the fan is configured to drive an external airflow into the first box from the sewage inlet, and drive the external airflow to enter the fan after passing through the cyclone separator, such that the solid-liquid mixed garbage enters the first box through the sewage inlet.
