PRESSURIZED SCREW SYSTEM USING AIR LOCKS FOR WASTE DISPOSAL

摘要

Hazardous waste is treated by shredding and then passing the material through an enclosure by means of a conveyor through direct steam impingement. The enclosure is maintained at a pressure greater than or equal to atmospheric pressure in order to maintain steam temperature at or above 212° F. Pressure locks are positioned at an inlet and discharge of the enclosure. The pressure locks allow transport of waste material into and out of the enclosure while maintaining a pressure differential between the interior and exterior of the enclosure.

1. A waste disposal system for disposing of waste materials comprising:
an enclosure having an interior and including an inlet opening at one end and a discharge opening at another end; a conveyor positioned between the inlet opening and the discharge opening; a steam source and a conduit connected from the steam source to the interior of the enclosure; an inlet pressure lock chamber positioned adjacent to the inlet opening; and a discharge pressure lock chamber positioned adjacent to the discharge opening.
