DEVICE AND METHOD FOR TREATING GAS EFFLUENTS IN A CHAMBER CONTAINING INTEGRATED HEATING/COOLING ELEMENTS IN THE FORM OF THIN PLATES

摘要

The invention concerns a method and a device for purifying air and for recuperating polluting gases with selective adsorption, desorption and condensation/adsorption cycles. The invention is characterised in that the air loaded with single or multiple pollutants enters (6) a chamber (19) and passes through one or several adsorbent materials (2) located between two heat-regulated elements slightly spaced apart (1) for fast, homogeneous and perfectly controlled heating/cooling of said adsorbents. When the detector (9) indicates that the adsorbents are saturated, the air inlets and outlets are isolated. The heating elements quickly raise the temperature of the adsorbents up to a set temperature, a carrier gas (8) passes through the adsorbents in counter-current and transfers the polluting gases towards the integrated condensation unit using the condensation products whereof a highly cooled part (4) is used for condensation (3) and the other is conveyed to the storage unit (10). If necessary, the residual gaseous pollutants are conveyed to a secondary small adsorber (5) which will restore said gases into the main adsorber in adsorption mode.
