Abstract
A gas suction filtration apparatus in which a liquid filter medium is contained in a closed container. A gas intake pipe is positioned so as to introduce the gas to be filtered into the bottom of the container and a suction device applies a suction force to the upper part of the container to draw the gas through the liquid filter medium. Gas-liquid mixing plates are disposed in the container which have numerous holes for passage of the gas therethrough. The mixing plates have diameters only slightly smaller than that of the container, and preferably the gap between the outside diameter of the plates and the inside diameter of the container is smaller than the diameter of the holes so that substantially all of the gas to be filtered must pass through the holes to facilitate contact between the gas and the liquid filter medium.
Claims11
A gas suction filtration apparatus comprising:
- a closed cylindrical container for a liquid filter medium with an upper space therein;
- a gas intake conduit pipe for introduction of the gas to be filtrated into said filter medium, said gas intake conduit pipe having its intake external to said container and its exhaust interior to a bottom of said filter medium;
- a gas suction means communicating with the upper space for application of a suction force to the upper space;
- and
- plural gas-liquid mixing plates with numerous pores on their surfaces for enhancing contact between said filter medium and the gas to be sucked, said mixing plates being rotatable about an axis of said container and each having an outside diameter slightly smaller than an interior diameter of said container so that substantially all of the gas to be filtered must pass through said pores in said mixing plates to facilitate contact between the gas and the liquid filter medium,
- each of said mixing plates further comprising a skirt about its periphery which extends toward the bottom of said container to facilitate capture of the gas so that more gas finds passage through said pores.
A gas suction filtration apparatus comprising:
- a cylindrical, closed container for a liquid filter medium, the container having an upper space above the filter medium;
- intake means for introducing a gas to be filtered at a bottom of said container and suction means for applying a suction force to the upper space for drawing the gas through the liquid filter medium;
- at least one circular mixing plate in said container between the bottom thereof and the upper space which has a plurality of holes for passage of the gas therethrough, said mixing plate having an outside diameter and said cylindrical container having an inside diameter which differ by less than a diameter of said holes so that substantially all of the gas to be filtered must pass through said holes in said mixing plate to facilitate contact between the gas and the liquid filter medium;
- and
- means for rotating said mixing plate about the axis of said cylindrical container.
