<p>PURPOSE:To avoid environmental pollution by a method wherein vulcanized rubber is heated to desulfurization temperature by imparting microwave energy and heating air thereto to regenerate it, while gas of bad smell generated is burned to deodorize it and part of the processed gas is used as heating gas for desulfurization. CONSTITUTION:After selection 12 of the kind of waste vulcanized rubber in a raw material 11, the rubber is formed into powder in a crushing process 13 and rubber processing oil or regenerating agent is added to the powder of the rubber, which is mixed and adjusted 14 and then is heated to a specified temperature in a microwave heating process 15 to effect depolimerization reaction, wherein a burning type deodorizing device 31 is connected to discharge gas of bad smell produced by heat in a desulfurization precess from the process 15 to deodorize it so that part of the processed gas is regulated to a temperature close to the desulfurization temperature of the rubber to return it to the process 15 for reuse as heating air. The desulfurized rubber is passed through a cooling process 32 and a refining process 17 to be prepared as regenerated rubber 18 or passed through a mechanical heating means 33 and cooling process 34 to produce a regenerated rubber 18.</p> |
