<p>PURPOSE:To recover oil from waste resin in high efficiency, by carrying out thermal cracking of a waste resin in a dry distillation furnace in a state shielded from air, cooling and condensing generated dry distillation gas and separating impurities from liquefied product with a centrifugal separator. CONSTITUTION:Roughly crushed waste resin is charged to a dry distillation furnace 5 and heated with a burner to start the dry distillation and generate dry distillation gas. The generated dry distillation gas is condensed by cooling and the condensed liquid and noncondensed gas are collected in a tank 7. The condensed liquid is treated with a dust separator 10 to remove impurities, purified and introduced into a centrifugal separator 39. Heavy water, light oil and solid impurities are separated by centrifugal separation taking advantage of the specific gravity difference. The light oil is stored in an oil tank as a high- quality fuel oil.</p> |
