Analysis of the aspiration system and gas cleaning for the cooling zone of the sintering machine for phosphorite ore

Abstract

This study describes the gas emission aspiration and purification system, which is a crucial component of the life support system for a mining and processing plant. The aspiration system aims to maintain favorable working conditions and prevent the increase of dust content and harmful emissions in the air of working areas beyond the maximum permissible values. This study addresses the cleaning of aspiration and gas emissions in the technological zones of sintering machines during the sintering of ore phosphate material. It provides technical solutions for cleaning gases during the sinter cooling process, considering the condensation of moisture from gases inside exhausters. The text also reveals the technological parameters for the functioning of foam apparatuses, cyclones, and splash catchers. The process of cleaning gases in the technological cooling zone of the sintering machine is carried out in two parallel foam apparatus, using both dry and wet methods.
