A Centrifugal Drum-type Reactor for Fast Thermal Treatment of Hydrargillite
https://doi.org/10.18412/1816-0387-2016-1-13-28
Abstract
Main stages of development of a pilot centrifugal drum-type reactor for manufacturing an X-ray amorphous product (50 kg/h) of hydrargillite activation are reported. Characteristics features of the product are a high reactivity and the specific surface area as large as two orders of magnitude of the initial area. The new reactor is shown to consume as low energy as a half of that consumed by the industrial thermal activation of hydrargillite in flowing flue gases. A mathematical model is suggested for the process of centrifugal thermal activation of hydrargillite to consider the evolution of the heat state of a particle in the course of its heating, dehydration, and cooling. The model allows the energy consumption to be estimated at all the process stages; it will be useful for developing standard series of the reactors.
