Methods for dechlorination disposal of polyvinyl chloride wastes and apparatus thereof.

摘要

The present invention provides methods for making gases generated in the treatment of polyvinyl chloride wastes harmless by neutralization and dissolving, and an apparatus thereof, and a suction-type solution filter container to be used, and providing to shape useful materials or components, such as activated carbon with excellent adsorbability, from the post-treated residues of the wastes. Polyvinyl chloride wastes are put in the sealed container 1 and heated at 400 DEG C or less without oxygen or with air-blocked condition; the gases from the wastes, such as chlorine or hydrogen chloride, are sucked to extract from the container; the extracted gases are introduced into the suction-type solution filter container with liquid filtration agents to pass therethrough; chlorine is removed and reduced in volume from the wastes in the sealed container.
