    摘要: A fluidized-bed process and apparatus involving a vertical column containing a plurality of perforated trays, each tray having a weir disposed on its upper surface to divide that surface into first and second sections, each of which has a plurality of apertures. One section of each tray constitutes 80 to 95% of the total tray surface area. Location of the weir on successive trays alternates from side to side of the column to provide for cross-flow of the fluidized material on the trays.

    摘要: In a process for the purification treatment of a waste gas containing gaseous pollutants, including the steps of upwardly introducing the waste gas into the bottom of a tower a multiplicity of stepped trays and at the same time introducing an activated carbon into the top of the tower, allowing the waste gas and the activated carbon to come into contact to form a fluidized bed each on the stepped trays, thereby causing the gaseous pollutants in the waste gas to be adsorbed on the activated carbon the waste gas can be continuously purified by recycling the activated carbon spheres and adopting, as the stepped trays, perforated plates of a specific design.

    摘要: An apparatus for purifying an exhaust gas containing solvent vapours by bringing the exhaust gas and adsorbent particles into continuous mutual contact to adsorb the solvent vapours onto the adsorbent particles and subsequently regenerating the adsorbent particles containing the solvent vapours thus adsorbed and simultaneously recovering the solvent vapours. In regenerating the adsorbent particles containing the solvent vapours, the apparatus is capable of advantageously using an incondensable inert gas as a carrier gas for regenerating the adsorbent particles.
