1. the auxiliary polymeric adsorbent pressure-variable adsorption of a nitrogen blowing reclaims the method for organic exhaust gas, it is characterized in that adopting the absorption that hockets of two absorbers that polymeric adsorbent is housed, when one of them absorber adsorbs, another absorber carries out adsorbent bed regeneration, adsorbent bed regeneration adopts the auxiliary vacuum desorption of nitrogen blowing, and concrete steps are:

  • (1) absorption;

    enter absorber containing the waste gas of volatile organic matter through gas gathering system and adsorb;

    (2) desorption;

    in absorber, adsorbent is through vacuumize-nitrogen blowing process, and the VOCs being adsorbed is desorbed and gets off to obtain desorption gas from adsorbent;

    (3) reclaim;

    desorption gas is by condensation or absorb processing recovery VOCs, and adsorbent is wherein macroporous absorbent resin.
