System for measuring, monitoring and control of bubble size in flotation columns

摘要

System for measuring, monitoring and control of bubble size in flotation column. The present invention describes a system online measurement, monitoring and control of the size of bubbles for testing a pilot or bench flotation column.His main area of application is the mineral processing, the system is coupled in the base of flotation columns, being composed by three parts: Board of generation of bubbles; camera display for obtaining digital images of bubbles and chamber injection of bolh The column flotation.The bubbles generated in a controlled manner in the chamber to generate bubbles, amount to the display chamber where they are obtained from digital images of bubbles, and these images processed and analyzed in a computer in real time (onhine). After the bubbles are introduced on the basis of the flotation column through a chamber of injection of bubbles.The automated control of the size of the bubble is performed by varying - if the dosage of surfactant (flow) injected into the chamber to generate bubbles as a function of the difference between the diameter of bubble and the bubble diameter measured desired ("set point").
