Abstract

PURPOSE: To perform an efficient treatment in a sludge evaporation drying process using oil as fluidizing medium by a method wherein dried slurry is separated into oil and solid, the solid is dry-distilled to recover oil, and the dry-distilled oil is used as replenishing oil.
CONSTITUTION: The sludge 1 is mixed with a circulating oil 14 to form the slurry, which is sent to an evaporator 3 to separate water 4 from the sludge 1. The dehydrated slurry is guided to a centrifugal separator 5 where recovered oil 6 and solid 7 are separated. The solid 7 is charged in a dry-distillator 9 together with combustibles such as coal 8. This process produces a dry-distilled oil 10 consisting of oils from the solid 7 and from the coal 8. The dry-distilled oil 10, along with recovered oil 6, is used as the circulating oil 14. Meanwhile, combustibles such as gas and coke from the dry-distillator 9 and combustible mixture 11 from the solid 7 are used as fuel for a boiler 11 and the dry-distillator 9.
