APPARATUS FOR REMOVING CHLORINE OF CHLORINE-CONTAINING POLYMERIC RESIN AND CHLORINE REMOVING METHOD

摘要

PROBLEM TO BE SOLVED: To take out generated hydrogen chloride without mixing the same with heating gas while preventing the corrosion caused by hydrogen chloride in an apparatus for removing the chlorine from a chlorine-containing polymeric resin and a chlorine removing method using the same and to use the residue of a resin material after dechlorination treatment as a raw material for a furnace as it is without separating a heating medium from the residue. SOLUTION: In a rotary kiln type chlorine removing apparatus, the main body A of the apparatus is constituted of an outer pipe 1 and the inner pipe 2 arranged therein and the interior of the inner pipe is set to a passage for a resin material to be treated and the space between the inner pipe and the outer pipe is set to a passage for heating gas. In the dechlorination method using this apparatus, as a heating medium to be supplied into the inner pipe along with a chlorine-containing polymeric resin material, powdery granular matter usable as an iron source of a furnace, an iron source reducing agent, fuel or an auxiliary raw material, especially pref., powdered coke is used.
