REACTOR FOR THE HYDROTHERMAL OXIDATION TREATMENT OF ORGANIC MATTER IN A REACTIONAL ENVIRONMENT

摘要

Reactor for hydrothermally oxidizing an organic material in a reaction medium which comprises in particular: a longitudinal body provided with a cold interface flange; an inner tube, placed in the body to form an annular zone and comprising a cold end and a hot end, the inner tube delimiting an internal reaction zone in fluid communication with the annular zone through an opening disposed in the hot end of the inner tube ; a stirring means of the reaction medium located in the inner reaction zone and rotatably mounted around the longitudinal axis of the body; means for injecting the organic material to be treated into the inner tube. The inner tube is rotatably mounted on the cold flange to be rotated about the longitudinal axis; the injection means comprises a sleeve, placed inside the inner tube, having a bore which defines a passage of the organic material to be treated from the first end to the second end of the sleeve; the stirring means comprises blades fixed on the inner wall of the inner tube and spaced from each other in a longitudinal direction of the inner tube, rotated by the rotation of the inner tube, and a plurality of counter blades fixed on the wall; outer sleeve and spaced apart from each other in a longitudinal direction of the sheath.
