A device for producing and treating a gas stream is provided that includes an enclosure, of which the lower part is submerged in a liquid supply open at the top and includes at least one liquid intake opening. The submerged lower part of the enclosure contains a volume of this liquid and at least one opening for discharging a gas stream, positioned above the surface of the volume of liquid contained in the enclosure. The device further provides for injecting a gas stream including at least one injection conduit and extends in the upper part inside the enclosure outside the volume of liquid. During operation of the device an incoming gas stream is introduced to create an outgoing gas stream, treated by direct contact with said volume of liquid that is discharged outside the enclosure. A facility inclusive of the device and method of operation are also provided.

A swirl air/liquid air purifier comprises: a liquid accommodating disk, having a liquid accommodating space formed in a recessed status for accommodating a liquid; an air discharging pipe, disposed at a top end of the liquid accommodating disk and upwardly extended so as to be formed as a hollow body, wherein a bottom end thereof has a bottom base which is sealed at the top end of the liquid accommodating disk, the bottom base is formed with a plurality of air inlet holes arranged adjacent to a periphery of the air discharging pipe, one side of the air inlet hole is downwardly extended and obliquely inclined thereby forming an inclined guiding plate/pipe allowing a swirl airflow to be generated; and an air suction fan, disposed in the air discharging pipe.

Provided is an air purification apparatus and method. The apparatus comprises a body having a cavity, an air intake, and an air exhaust. A water reservoir, disposed within the cavity contains a fluid and is in fluid communication with the air intake. A first chamber is disposed within the cavity and is in fluid communication with the water reservoir and the air exhaust. A solar power assembly attaches to the body, the solar power assembly has one or more solar panels. The air purification apparatus has a battery in electrical communication with the one or more solar panels.

A wet scrubber having a body that is molded from a plastic material in combination with a nozzle insert that is removably received in the inlet of the wet scrubber and configured to optimize the speed of fluid flow entering a mixing chamber provided in the wet scrubber. Interchangeable nozzle inserts allow to optimize operation of the wet scrubber for different processes the wet scrubber is operating in conjunction with.

A liquid filter apparatus for gas/solid separation includes a housing with a filter chamber, a semiconductor process gas inlet, and a process gas outlet. The filter chamber forms a liquid reservoir, and the semiconductor process gas inlet and the process gas outlet are in communication with the filter chamber. The housing further includes a filter liquid inlet and a filter liquid outlet, which are in communication with the liquid reservoir for delivering and removing filter fluid, respectively, to and from the liquid reservoir.

An exhaust configuration for a wet scrubber. The exhaust configuration includes a diffuser that is attached to the wet scrubber and which defining an outlet for discharging scrubbed air and paint laden water from the wet scrubber. Attached on lateral sides of the diffuser are wings. The wings extend away from the outlet.

The present invention is a portable air purifier device intended to be attached to the belt or to the neck of the user and generate purified air enough to breath easily and adequate to make an air curtain to push a way ambient air. Principle of the operation of this device is to push inlet polluted air through layers of ionized water. Water will absorb particles and copper and silver ion kills possible air born bacteria and produce clean air. The purified air will be then delivered to the face of the user either by a flexible hose to a mask or through several flexible hoses to form an air curtain in front of a user's face.

An air scrubber has an electrically driven fan and a drum having a mat forming a closed circulating band spanning a support of the drum. The mat is electrically rotatably driven about a rotation axis, wherein a lower part of the drum is immersed in a water basin. The mat can be removed from the drum by a movement in the axial direction and pushed back on again by a movement in the axial direction.

Processes for separating methane from a gas mixture that comprises methane and C.sub.2 gas, including C.sub.2+ gas, and other gases, including CO.sub.2 and H.sub.2S, that are based upon formation of gas hydrates, and systems useful for implementing such processes, are disclosed.

According to one embodiment, a dust collection apparatus includes a liquid supplier, a first member, and a liquid recoverer. One end of the first member is connected to the liquid supplier, one other end of the first member is connected to the liquid recoverer. The first member is conductive. The first member has a first surface including a plurality of trenches.
