Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense door production, in particular to a VOCS purification device for a paint spraying room of a civil air defense door. Background Art

[0002] The VOCS purification device for the paint spraying room of civil air defense doors refers to the purification equipment used to treat the volatile organic compounds (VOCs) generated in the paint spraying room. During the painting process, volatile organic compounds will be released into the air, which may have an impact on the environment and human health. Therefore, the paint spraying room is usually equipped with a VOCS purification device to purify and treat these harmful gases. The working principle of the VOCS purification device is generally to use adsorption, oxidation, desorption and other methods to convert volatile organic compounds into harmless substances or make them meet emission standards. Usually, the VOCS purification device in the paint spraying room is mainly composed of an activated carbon adsorption box and a combustion catalytic furnace, which filters the particulate matter in the harmful gas and converts the gas into carbon dioxide and water.

[0003] The activated carbon adsorption box in the VOCS purification device of the paint spraying room needs to be replaced after being used for a long time. The existing technology is mostly manual replacement. When replacing, the staff needs to pull out the box in the box and then replace the activated carbon. Due to the large volume of the activated carbon adsorption box, when replacing the protruding activated carbon inside, it is necessary to use ladders and other climbing equipment to replace it, which increases the replacement time of the activated carbon. Replacing the activated carbon adsorption box may require shutting down or suspending the painting operation, resulting in interruption of the painting production, affecting the work progress and production efficiency.
