METHOD FOR ENHANCING CHEMICAL REACTIONS

摘要

The present invention relates to enhancing chemical reactions and particularly reactions in a continuous system. The invention comprises circulating a fluid mass through the system at a selected rate of flow, introducing a chemical agent into the fluid mass, mounting two relatively straight tubes of different diameters in concentric radially spaced relationship to form an annular passage of substantially uniform thickness and isolating said tubes from each other to prevent direct transmission of sonic resonant energy from one tube to the other. The fluid mass is passed with said chemical agent introduced therein through the passage, setting up a cavitation condition throughout the length and circumference of at least one of said tubes in the ultrasonic range and transmitting said cavitation condition in a radial direction relative to the annular passage at a multiplicity of locations directly to the fluid mass and the chemical agent therein simultaneously and uniformly throughout the entire length and perimeter of the annular passage while said fluid mass and accompanying chemical agent are in transit through said annular passage. Then the resulting combination of said fluid mass and said chemical agent is collected at a discharge location. The improved method of this invention is useful in processing and recovery of metals and cuts down on the processing time over known methods and maximizes metal recovery.
