Abstract
A system for treating liquid containing waste material which includes a reaction vessel for treating other material to achieve a reaction which includes the formation of hot gases. The system includes a dryer adapted to receive the hot gases from the reaction vessel, and these hot gases are introduced to the dryer for heating the waste material to a temperature in excess of the boiling point of the liquid in the waste material. The waste material is circulated within the dryer to maximize the exposure of the waste material to the heat in the hot gases. Waste gas generated by the boiling of the liquid is withdrawn from the dryer, and a solid portion of the waste material is discharged from the dryer and delivered to the reaction vessel. This solid portion provides at least some of the fuel value required for operating the heating means of the reaction vessel. The hot gases from the reaction vessel are preferably introduced to a longitudinally and centrally located pipe cluster of the dryer whereby, upon rotation of the dryer, the waste material is continuously moved back and forth between said pipe cluster and the inner wall surface of the dryer.
