Device and procedure for continuous treatment of waste

摘要

An apparatus and procedure for efficiently sterilizing waste material or products. The apparatus includes a reactor in the form of a cylindrical container housing two cylindrical tubes, a larger first tube and a smaller second tube. A first helical blade extends inwardly from the inner surface of the second tube, and a second helical blade bridges the outer surface of the second tube to the inner surface of the first tube. As the set of tubes is rotated in unison, material flows in one direction within the second tube and in the opposite direction in the space between the tubes. This axially compact design allows non stop introduction and extraction of waste, efficient use of heat energy, provided by steam injected into the reactor through a steam port, and allows for material to be input into and extracted from the device both at one end of the reactor.

主权项

1. An apparatus for treating waste comprising:
a reactor comprising an external static tank capable of containing the waste under pressure, a reverse rotor disposed within the external static tank, the reverse rotor comprising a first tube and a second tube, each of the first and second tubes being cylindrical and having a longitudinal axis, the first and second tubes being coaxial about their longitudinal axes, the first tube being larger in diameter than the second tube, an inner helical blade disposed on an inner wall of said second tube defining a first flow path for waste when the reverse rotor is rotated about the longitudinal axes of the first and second tubes, an outer helical blade bridging an outer surface of the second tube and an inner surface of the first tube, the outer helical blade defining a second flow path for waste when the reverse rotor is rotated about the longitudinal axes of the first and second tubes, the first and second flow paths being directionally opposite with respect to the longitudinal axes of said tubes, such that rotation of the reverse rotor in the rotational direction about its axis causes movement of waste in two axially opposite directions, wherein the first and second tubes are joined together by the outer helical blade and rotate in the same rotational direction.
