Centrifugal separator

The separation efficiency of a centrifugal gas separator is heightened by a rotary drum of a bottomed double-walled construction which allows a gas mixture to be admitted into the drum interior circumferentially rather than axially through two or more holes perforated into the central portion of the inner wall thereof. The inner and outer walls of the drum define a space that connects with the holes and which is further communicated with a gas mixture storage tank via a passage provided in the upper end cap and a gas inlet tube axially contained within a drive shaft movably supported by a damper and integrally joined to the upper end cap. Both end caps are perforated with a plurality of orifices and the entire mechanism is enclosed by a bottomed cylindrical vacuum tank provided with outlet pipes for discharging the separated gases obtained through the orifices. Circumferentially admitting the gas mixture through the aforementioned holes during rotation cancels gas flow in the radial direction, enables the angular velocity of the gas mixture to exceed that of the velocity of the drum and enhances convection currents, whereby the separation efficiency surpasses that of the centrifugal separators of the former art.
