Abstract: A method and apparatus for cleaning a gas comprising a rotatable centrifugal cylinder having passageways for flowing a gas stream with a liquid stream through the cylinder to centrifugally remove the particulates from the gas stream with the liquid stream; turbine blades positioned inside the cylinder and connected to the cylinder to rotate the cylinder when the liquid stream flows through the turbine blades; fan blades positioned inside the cylinder and connected to the cylinder to rotate with the cylinder to pump the gas stream through the cylinder; and a pump connected to a reservoir of liquid, for pumping the liquid stream.

Abstract: A system and method of cleaning a gas of undesired particulate, aromas, and gases is disclosed. The invention uses a centrifugal scrubbing space to liquid wet a gas and includes a container for containing a liquid with a pump to circulate the liquid. The gas is pumped from outside the container, through an inlet cylinder, a fan wheel, a scrubbing space, over a surface of the liquid, through a cyclone space, and out a top outlet. The liquid may be pumped with a standard pump, a cone-shaped rotatable case attached to the fan wheel, or a pump with a non-rotatable case and an impeller attached to a same shaft as the fan wheel. The gas inlet may be positioned below or above the apparatus, and the fan motor may be positioned inside or outside the apparatus.

Abstract: A system and method of cleaning a gas of undesired particulate, aromas, and gases of the type utilizing a centrifuge with various combinations and apparatus used to liquid wet a gas stream is provided. The gas scrubber of the present invention includes a container for containing a liquid having a surface forming a space between said surface and the container top; a motor having a rotatable vertically mounted shaft mounted above said top with said shaft connected to and rotatable with a centrifuge cylinder having an inlet positioned outside of said container and having an outlet positioned in said space. Said cylinder contains fan blades to draw gas from said cylinder inlet and out said cylinder outlet. A vertically mounted rotatable siphon pipe, connected to said shaft, that has an inlet positioned below said surface and an outlet positioned proximate said centrifuge inlet to draw liquid up and out to the centrifuge inlet and flow down the centrifuge wall to clean the wall and mix with said gas.

Abstract: A system and method of scrubbing gas utilizing a liquid to wet a gas stream is provided. The scrubber comprises a container containing a liquid; a tube having a tube inlet opened exterior of the container connected via a throat to a tube outlet allowing a gas to flow from exterior the container into the space above the liquid; a motor having a rotatable shaft; a siphon pipe connected to the rotatable shaft having a siphon inlet disposed below the liquid surface and a siphon outlet positioned above the surface proximate the tube throat; wherein the rotating siphon pipe draws and rotates the liquid through the siphon pipe into the tube throat drawing the gas into the throat mixing with and scrubbing the gas; and a second opening in the container for discharging the scrubbed gas from the container.

Abstract: A system and method of cleansing a gas of undesired particulate, aromas, and gases of the type utilizing a liquid to wet a gas stream is provided. The gas scrubber of the present invention including: a container having a bottom wall and a top wall interconnected by a side wall and containing a liquid therein, the top wall having an opening formed therethrough by a sleeve having an inlet opening and an outlet opening interconnected by a throat, and a mechanism for pressurizing the liquid that may include a pump for directing the pressurized liquid through a converging nozzle discharging the pressurized liquid into the throat to draw a gas into the inlet opening and mix with the pressurized liquid in the throat and discharging the mixture into the container releasing the gas from the mixture and discharging the gas to the atmosphere. Undesired gases are removed from the original stream by absorption in the liquid and particulate is dropped out of the gas stream after being wetted by the liquid.
