RESEARCH OF PENTHAERITRITH ABLATION AT ITS PULSING FLUIDIZATION

SECAIJ

Abstract

The experimental estimation of agency of some technological parameters of pulsing fluidization of a penthaeritrith layer on its ablation from the working chamber of the apparatus is executed. The description of the laboratory-scale plant and a technique of conducting experiences is resulted. With application of the instrumental methods the disperse composition of penthaeritrith, subjected to fluidization is defined. Removal possibility of "small" fractions of a material from the working chamber is sized up. It is shown, that material ablation increases proportionally to increase in speed of fluidization agent (air). The increase in a ripple frequency of air leads to considerable decrease in ablation. It’s established fact of decrease in ablation at decrease of initial altitude of a material layer in the working chamber. Empirical dependence for calculation of a constant of ablation speed is gained. The equation for calculation of process kinetics is resulted. Satisfactory convergence experimental and design data on penthaeritrith ablation from a pulsing layer is ascertained. The gained information can be useful to development engineers of production engineering of processing of disperse materials in systems "gas-solid".
