| description | The invention discloses a novel volatile organic compounds environmental-protection governance recovery method and device, relates to the volatile organic compounds (VOCs) containing industrial waste gas environmental-protection governance and organic compound recovery technologies, and is used for environmental-protection governance and organic compound recovery of VOCs containing industrial waste gas in plastic soft packing printing (dry laminating) industry, coating industry, petrochemical industry, fine chemical industry and the like. The VOCs containing industrial waste gas after pretreatment is absorbed and purified by an adsorbent in a purifying bed, so as to realize up-to-standard emission; the adsorbent adsorbed with saturation organic compounds is subjected to heating-up desorption, condensing recovery, vacuum desorption and condensing recovery in a nitrogen environment and at the temperature of 80 DEG C-120 DEG C, so as to realize secondary recovery of an organic solvent. The governance circulating period is short, the governance ability of the device is large, operation is safe and efficient, the unit governance cost is optimized, more than or equal to 50% of the desorption cost can be saved relative to a conventional process, the recovered organic solvent has good quality, and environmental protection, energy saving effect and economic benefits are good. |
