International ClassB01D 053/04Foreign Application Priority Data1995-09-07 FRAbstractA process and device for scrubbing flows of gaseous effluents loaded with polluting substances, wherein the effluents are caused to circulate through a device including an array of scrubber units (4a to 4n) juxtaposed in an enclosure (3), each containing materials adsorbing the substances. When the adsorbing load thereof is saturated and for the scrubber units (4) to regain the scrubbing capacity thereof, they are selectively and successively isolated by a mobile collector (8) during the time required for their desorption by heating and for the substances to be transferred by an auxiliary fluid (a fraction of the circulating effluents for example or a gas delivered selectively to the inlet of the scrubber unit to be desorbed by an auxiliary circuit), and the substances mixed with the auxiliary fluid are possibly transferred towards a reactor (10) suited for removing them. The process can be applied for concentrating and scrubbing of polluting substances such as VOCs or gas dehumidification.Field of SearchWith sequential cleaning of plural unitsPneumatic reverse flushing With heating or cooling With plural indirect heat transfer steps on solid sorbent or gaseous fluid mixture or constituent thereof Heating and cooling Inorganic gas or liquid particle sorbed (e.g., vapor, mist, etc.) Hot sweep gas And regeneration Plural solid sorbent beds With heat exchange means With rotating gas distributor Zigzag arrangement of flat solid sorbent beds for parallel flow Movable solid sorbent bed (e.g., fluidized bed, etc.) Rotating solid sorbent bed And means for driving gas flow (e.g., pump, blower, compressor, etc.) Compressor With means for regenerating solid sorbent With recovery or separation means for desorbing fluid Plural canisters Gas contacting means | |
