Popis: This study analyzes the specific properties and technological parameters of gas emissions from chemical-energy processes [1], considering the volume and content of toxic components, as well as the operating experience of gas emission purification systems at existing phosphate plants. A three-stage system of apparatuses is studied for gas purification: an ensemble of single cyclones, foam aggregates irrigated with aqueous caustic soda solution. It is established that cyclones are the most suitable apparatus for dry gas cleaning, and that their diameter should be no more than one meter to increase the efficiency of cleaning. It has been demonstrated through scientific research that when cleaning phosphorite sintering gases, which have a volume exceeding the capacity of a single cyclone, it is necessary to use group cyclones. These are several cyclones combined into one group with a common hopper. It is recommended that the cyclone speed be increased by approximately 50% in comparison to the standard speed, which contributes to an increase in the efficiency of the separation of impurities in the purified gas.
