Embodiment
[0068] Adopt the treatment system and the treatment method of VOCs waste gas provided by the present invention to process the battery production enterprise waste gas, specifically as follows:
[0069] Adsorption: VOCs-containing exhaust gas (VOCs concentration greater than 6500ppm) enters the first-stage adsorption tank through the first-stage exhaust gas delivery pipeline, removes VOCs in the exhaust gas through activated carbon adsorption, and then enters the second-level adsorption tank through the second-level exhaust gas delivery pipeline, and is again adsorbed and desorbed by activated carbon After removing the VOCs in the exhaust gas, it is discharged to the atmosphere through the clean gas discharge pipe, and the emission concentration of VOCs is less than 45.5ppm;
[0070] Desorption: High-pressure water vapor enters the first-level desorption tank and the second-level desorption tank through the first-level steam delivery pipeline and the second-level steam delivery p...
