Title:
TREATMENT OF PLASTIC AND ITS APPARATUS
Document Type and Number:
Japanese Patent JP3575914
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve an operability and energy efficiency of a thermal decomposition of a plastic and also a quality and recovery ratio of a heat decomposed product.
SOLUTION: A plasticizer is removed by bringing a plastic into contact with a material having an absorptivity of the plastic in a heated state. A lead component is removed by using acetic acid and hydrogen chloride. The plastic is thermally decomposed after forming the plastic into thin layers. The molten plastic is heated from the interior. A heated gas having low activities is blown into the molten plastic. The plastic is decomposed by adding a heavy oil or a plastic including no halogen to the molten plastic. The thermally decomposed gas is treated by an active carbon and a hydrogen chloride trapping agent. The thermally decomposed gas is distilled by using a distilling column having plate trays having variable number of penetrating holes.
