摘要
A debris-cleaning apparatus for toxic waste sites is mounted on a trailer (T). The apparatus includes a chamber (10) and a crane (70) that lowers a basket drum (200), filled with contaminated debris, into the chamber (10). The drum (200) is cylindrical and has journal shafts (210) at either end which drop into bearings (12) in the chamber (10). The drum (200) can be coupled to a drive motor (350) to rotate the drum (200) during a washing operation in which the chamber (10) is filled with heated detergent solution and agitated. The drum (200) surface is perforated. The agitation is increased by pumping the detergent solution into eductors (400) inside the chamber (10), each eductor (400) including a nozzle (410) and a venturi (430) concentric with the nozzle (410); the jet entrains large amounts of detergent to create a high volume turbulent flow inside the chamber (10). The chamber (10) is then drained into a holding tank and the debris is sprayed with detergent from orifices (234) drilled through the drum walls.
