Abstract
This article describes new constructive solutions in the design of multistage shelf dryers and their efficiency in terms of the environmental safety of production. The urgency to develop the multistage shelf devices for the drying process is substantiated. The features of the improved shelf contacts are presented. The physical model of the interaction of “gas”-“solid” flows and the main advantages of the declared constructive solutions are described. Emissions of solid particles with outgoing gas can be significantly reduced by developing mechanisms for controlling the particles’ motion on the shelf and predicting the distribution law of particles in the device (while obtaining a reliable and uniform distribution of the gas flow). A comparative analysis of the solid particles’ concentration in the devices with different shelves (in comparison with classical fluidized bed devices) is presented. The necessity to use computer modeling in the optimization design of environmentally friendly drying units is substantiated. The computer modeling results of the hydrodynamic conditions of the gas flow in the dryer are presented. New designs of shelf units allow controlling the motion of dispersed particles in the workspace of the device. At the same time, it is possible to predict dust and small particles’ behavior and ensure their reliable trapping from outgoing gases. The obtained results have the prospects for further implementation due to the analysis of the dryer’s technology readiness level and the investigation of a roadmap for entering the domestic market.
