Background technology
Major part Chemical Manufacture producer can all generate tail gas in process of production at present, in order not to pollute air, be required forThe tail gas that it is produced is handled, then could be emptied, however at present in the Chemical Manufacture producer of some organics, theyThe tail gas of generation is often with a large amount of low-boiling-point organic compound, however the tail gas absorbing system that they use but can not be effectiveThese organic matters are recycled, and have been exhausted directly in air, bring atmosphere pollution, while also resulting in the waste of material.
Carbon adsorption is most widely used recovery technology, and principle is the porous structure using adsorbent, will be discardedIn VOC captures, the organic exhaust gas containing VOC is made into VOC absorption by active-carbon bed, exhaust gas is purified and is discharged into airIn.After carbon adsorption reaches saturation, desorption and regeneration is carried out to the carbon bed of saturation；It is passed through vapor to release VOC strippings, and and waterSteam forms vapour mixture, leaves adsorbent bed together；It is liquid with condenser cooling steam mixture, is then detached againRecycling.
But current adsorbent equipment, it is difficult to there is preferable adsorption effect, and exhaust-gas treatment quality is undesirable.
