Influence of design and technological parameters on the efficiency of the granular filter

Abstract

The main types of devices for separating dust from process gases are considered. Their advantages and disadvantages are indicated. Granular filters are noted as the most effective ones. They can work in a very aggressive environment, both chemically active and with high-temperature gases. The design of a granular filter with high efficiency of cleaning dusty gases is proposed. An experimental installation of a granular filter was created for experimental confirmation of the high efficiency of the proposed filter design. The material used in the experimental setup as a filter material, its mineralogical and chemical composition are described. The central composite rotatable plan of the fractional factor experiment was chosen as the main plan of the experiment. To conduct experimental studies, the studied factors and levels of variation were determined. Based on the results of the experiment, a regression equation was obtained that expresses the efficiency of the cleaning process from the structural and technological parameters of the granular filter in encoded form. Graphical dependence of the effect of main design-technological parameters of granular filter efficiency depending on the time of his work were done. The high efficiency of the proposed granular filter for cleaning process gases from highly dispersed dust has been experimentally proved.
