Apparatus for removing undesired matter from dirty gas comprising

• a chamber defining a downwardly vertical path for gas and fluid flow,
• means for introducing a fluid and a dirty gas substantially simultaneously into an upper portion of said chamber for passage downwardly through said chamber, said dirty gas containing undesired matter to be removed,
• means for drawing said gas and fluid downwardly through said chamber,
• support means carrying a plurality of small-diameter, generally spherical solids providing a large number of small venturi passages between adjacent solids and impingement surfaces, said support means being disposed across the path of flow of gas and fluid through said chamber so that the gas to be cleaned and fluid impinge upon said solids,
• outlet means for separately removing gas and fluid carrying said matter from said chamber, and
• means for vibrating said support means for shaking said solids and maintaining them free of adsorbed matter taken out of the gas.

• means for introducing a fluid and dirty gas substantially simultaneously into an upper portion of said chamber for passage downwardly through said chamber, said dirty gas containing matter to be removed,
• means for drawing said gas and fluid downwardly through said chamber at high velocity,
• support means carrying a plurality of small-diameter solids providing a large number of small venturi passages and impingement surfaces, said support means being disposed across the path of flow of gas and fluid through said chamber so that the gas to be cleaned and fluid impinge upon said solids,
• outlet means for separately removing gas and fluid carrying said matter from said chamber, and
• means coupled to said support means for vibrating said support means and the solids carried thereby to prevent matter removed from the gas from adhering thereto and blocking the passages therebetween.

• an apertured support plate carrying an array of a plurality of small-diameter solids providing a large number of small venturi passages and impingement surfaces, said array of solids being disposed across the path of flow of gas and fluid through said chamber so that the gas to be cleaned and fluid impinge upon said solids,
• outlet means for separately removing gas and fluid carrying said matter from said chamber, and
