Vertical evaporator/reactor for domestic and industrial effluents has dynamic core with driven spiral screw and inner injection tube

摘要

The evaporator/reactor consists of a vertical chamber (1) containing one or more dynamic cores (2), each comprising a tubeless spiral screw (3) turned by a motor (4) at the top or bottom and surrounding a double or multiple injection tube (5). The screw spiral can be conical or not, and its pitch can be progressive or simple, while the tube allows the injection of effluent (6) and heating fluid (7). The vertical chamber is e.g. about 150 cm in diameter by 300 cm high.
