This invention discloses a pollution-free emission treatment and purification device and method for nitrocellulose waste gas, belonging to the field of waste gas treatment technology. The device filters waste gas through filter holes, blocking dust particles. Water is sprayed from several nozzles onto the filter cartridge and comes into contact with the waste gas. Volatile organic compounds in the waste gas are removed through water absorption. The sprayed water directly impacts the outside of the filter cartridge, achieving backflushing of the filter holes and flushing out particulate impurities and sticky substances. Combined with the continuous rotation of the filter cartridge, the water thoroughly cleans the filter cartridge and filter holes, achieving automated unclogging of the filter holes. After impurities are flushed out of the filter holes, they are discharged through the discharge pipe. Opening the discharge valve outside the treatment tank allows the discharge of mixed materials and wastewater. The treatment tank can be cleaned without stopping the equipment, thus extending the service life of the equipment and facilitating efficient and stable purification of waste gas.
