Abstract:
1. A gas scrubber for scrubbing a gas by using a liquid to remove particulate and absorb gas molecules from the gas, comprising: a container having a reservoir for containing a liquid, the liquid having a surface that defines a space above the surface, the container also having a space outlet that connects the space to an exterior of the container; a scrubbing cylinder positioned in the space and having a top, a fan wheel space positioned at the top, an inside wall, an open bottom end positioned above the surface of the liquid, and a centrifugal scrubbing space extending from the fan wheel space downward along the inside wall; an inlet tube having an inlet positioned on the exterior of the container and an outlet positioned at the fan wheel space to provide a passage way that allows the gas to flow from the exterior of the container through the inlet tube, the fan wheel space, the centrifugal scrubbing space, over the surface of the liquid, through the space in the container, and out the space outlet; a pump having an inlet connected to the reservoir and an outlet positioned to pump the liquid to the centrifugal scrubbing space to allow the liquid to circulate from the reservoir, through the pump, to the centrifugal scrubbing space, and back to the reservoir; and a fan wheel positioned in the fan wheel space and mounted to a shaft having a motor for rotating the shaft and the fan wheel, the fan wheel pumping the gas through the passage way and discharging the gas tangentially at a high velocity in the centrifugal scrubbing space, to rotate the liquid with the gas in the centrifugal scrubbing space, to impact and centrifugally mix the particulate and the gas molecules with the liquid to scrub the gas.
