  • Patent number: 4817296
    Abstract: The machine of the invention comprises the following components interconnected through air conduits; a cage drum rotatably mounted in a housing, an air cleaner for intercepting mechanical impurities, an air cooler, an air heater with a steam heating element, an adsorber with respective inlet and outlet connections for steam admission and discharging a mixture of steam and adsorbed solvent. The machine comprises also a system of directional valves for changing the direction of air flow therethrough and a means for cooling and separating a mixture of condensates of steam and solvent, which is connected, through a device for condensate separation and discharge, to the outlet of the steam heating element of the air heater.The inlet of steam heating element is connected to an outlet connection for discharging a mixture of steam and desorbed solvent vapors from the absorber.

  • Patent number: 4769921
    Abstract: A process for recuperation of organic solvents in dry-cleaning machines comprising circulation of air first through a cleaning drum of a machine containing textile articles treated with an organic solvent and squeezed, a filter, an air cooler and a heater, and then through a cleaning drum with the articles, filter, air cooler and an absorber. The circulated air recovers the solvent from the articles which solvent is first condensed in the air cooler and then adsorbed in the adsorber. Simultaneously with circulation of air through the cleaning drum, filter, air cooler and heater effected first is desorption of the solvent adsorbed in the previous process cycle of the dry-cleaning machine operation from the adsorbent by means of steam which together with vapors of the desorbed solvent is condensed in the heater, followed by the removal, from the adsorber to the heater, of the remaining steam and its condensate due to the pressure drop in the adsorber-heater system by means of compressed air.
