Title: Evaluation of Pulse Jet Mixer Concentration Profiles to Track Slurry Suspension

Abstract

A series of tests were conducted to evaluate the mixing performance of pulse jet mixers. A pulse-jet mixing system involves an array of pulse tubes with nozzles directed toward the vessel floor inside the mixing vessel. Fluid is expelled from the pulse tubes during the drive portion of the PJM cycle. Fluid refills into the pulse tubes during the refill portion of the PJM cycle. This cyclical process can be used to mix slurries. Concentration profiles as a function of location and elevation in the tank were taken during the pulse jet mixer cycle at several radial locations within the mixing vessel: at the center, near the wall, and half-way between the center and the wall. The data are being examined to determine how the time during the cycle affects the solids suspension and settling. Examples will be presented for several particle types, concentrations, and pulse-jet operating conditions.
