Abrasion Resistant Controlled Cavitation Reactor

摘要

A controlled cavitation reactor is disclosed that is particularly suited to the treatment of abrasive fluids and slurries with a minimum of erosion and mechanical failure caused by abrasion. The reactor includes a generally cylindrical housing having a peripheral wall that extends between end plates. A rotor is rotatably disposed in the housing and has at least one outer peripheral surface spaced from the peripheral wall to define a cavitation zone therebetween. A plurality of bores extends through the peripheral surface of the rotor. The rotor may be formed with a central void zone between two lobes of the rotor with each lobe defining a separate cavitation zone with the peripheral wall of the housing. One or more inlet ports is arranged to introduce fluid to the housing tangentially and within one or more void zones. One or more exit ports is arranged to receive fluid from the housing tangentially within another void zone. As a result, fluid takes a spiral path into the housing, across the cavitation zone, and out of the housing. This greatly reduces sharp changes in direction and accordingly reduces abrasion and consequent damage.

主权项

1. A controlled cavitation reactor for treating a fluid flowing therethrough, the controlled cavitation reactor comprising:
a housing defining a substantially cylindrical internal chamber confined by a peripheral wall and end walls; a first rotor disposed in the internal chamber and being mounted for rotation therein, a peripheral surface of the rotor being spaced from a peripheral surface of the internal chamber to define a first cavitation zone therebetween; a motor coupled to the first rotor for causing selective rotation of the first rotor within the internal chamber of the housing; a plurality of cavitation inducing features on a peripheral surface of the first rotor; a fluid inlet port extending through the peripheral wall of the housing for introducing fluid to be treated into the controlled cavitation reactor; the fluid inlet port being oriented to introduce fluid into the internal chamber in a direction substantially tangent to the peripheral wall of the internal chamber and in the direction of rotation of the rotor; a fluid outlet port extending through the peripheral wall of the housing for extracting treated fluid from the chamber; the fluid outlet port being oriented to receive treated fluid from a direction substantially tangent to the peripheral wall of the internal chamber and from the direction of rotation of the first rotor.
