Abstract

The article deals with the screening process of complex pyrolysis products. It is envisaged to use drum screen as a unit for separation into fractions of pyrolysis products of drum screen. With the help of three-dimensional modeling and theoretical calculations using the theory of probability, calculated and experimentally validated screen model. On the developed and manufactured experimental psychological installation, studies were carried out with obtaining graphic dependencies, the study of physical properties pursues the goal of pyrolysis on the efficiency of screening in a drum screen. On the basis of graphic dependences, there are conclusions about the available parameters of the screening process of special pyrolysis products. Theoretical studies have been carried out on the presence of side effects on the effectiveness of selection in a drum screen. Recommendations are given for the use of sequential devices for the fractionation of complex pyrolysis products.
