PARTICLE SUSPENSION IN SPHERICAL VESSELS

Popis výsledku v původním jazyce

Performance of particle suspension using various agitators and jet configurations was tested in a spherical vessel. Although uncommon, spherical vessels can be found throughout the industry, most commonly as storage tanks or anaerobic digesters, however, there seems to be no data regarding how to efficiently facilitate particle suspension in this geometry. Therefore, assessment of the necessary power input for particle suspension and the corresponding level of homogenisation was performed utilizing video analysis. Of the devices used, most were capable of achieving just-suspended state, however achieving homogeneity in the whole volume was problematic. The best performing from the tested methods were the one which least enhanced tangential flow, such as Rushton turbine or PB6 agitator. Due to high difference in densities between the particles and liquid, jets were performing poorly. However, when applied to suspensions of comparable densities, their efficiency was one of the best.
