Abstract
In this article modelled processes of heat treatment of the technogenic waste – phosphogypsum – in a suspended state in a dehydrator mine. Its use greatly intensifies the processes of heat and mass transfer, due to the increase in the contact surface. The objective is to choosing a rational design of the installation. The theoretical velocity of the particles of phosphogypsum in the dehydrator, the fuel consumption and the amount of air for combustion are calculated. The necessary shape and dimensions of the plant sections were chosen to achieve optimum speeds. A computer simulation of the installation for heat treatment of phosphogypsum in suspension has been performed. This allowed us to determine the shortcomings of the design of the main units and to propose optimal parameters.
