Description

technical field [0001] The invention relates to the technical field of VOCs waste gas treatment, in particular to an activated carbon adsorption and catalytic combustion device for VOCs waste gas treatment. Background technique [0002] Industrial waste gas containing volatile organic compounds (VOCs) is one of the main sources of air pollution. At present, the main method of VOCs governance terminal control is adsorption regeneration method. The adsorption method widely uses activated carbon as the adsorbent. When the adsorption reaches the saturation of VOCs, the activated carbon needs to be desorbed by hot air, steam or pressure swing. This VOCs exhaust gas catalytic combustion system consists of a fixed adsorption bed and an online desorption device. The fixed adsorption bed absorbs the organic components in the exhaust gas into the activated carbon through the activated carbon filled in the bed, so that the exhaust gas is purified, and the purified clean gas passes thr...

Problems solved by technology

However, there are still the following defects: (1) Each fixed adsorption bed needs to be equipped with an online desorption device, which increases the cost and occupies a large area; (2) There are potential safety hazards when the online desorption device is in operation, and fire and explosion-proof devices need to be installed; ( 3) It cannot be used in flammable and explosive factory areas
