This technology focuses on VOCs (Volatile Organic Compounds) waste gas treatment, which combined the process of absorption, enrichment, parsing, catalytic pyrolysis, recycling etc., reaching the purpose of the \\\"package solving\\\". The specific content is: using the special adsorption material to absorb and enrich waste gas with big air volume and low concentration, then transform them into small air volume and high concentration. After that, waste gas through the process of catalytic pyrolysis, using clean gas to parse. The end-product are CO2 and H2O, aiming at the purpose of \\\"ultra low emission\\\".
