Kinetics of cyclone dust flotation separation in polluting industries

Abstract

Abstract This article describes the study of the kinetics of flotation separation of silicate and carbon dust phases of silicon cyclones. For research, we selected 50 samples of dust gas purification production of silicon to the Silicon situated in the city of Shelekhov of the Irkutsk region. The dust caught by bag filters can be applied as an additive in concrete, rubber products or subjected to processing for expansion of a scope of application. Silicate and carbonate phase of the cyclone dust silicon production separately represent the products in demand. The cost depends on the degree of purity, structure and particle size distribution. Describes the basic dependence of the flotation nanoscale this part of carbon and microsilica. Micro particles inherent in the formation of stable heterogeneous conglomerates. Dissimilar particles can both be introduced into the foam product and remain in the chamber reducing the quality of concentrates. To solve this problem, pulp conditioning is used with the help of sonochemical installations, which contributes to the separation of a large number of conglomerates. The effect of aeration on the flotation process of nanoscale particles is described. Conducting experiments on laboratory experimental flotation machine in different modes and with different flotation reagents. A method of conditioning the pulp, which increases the efficiency of flotation and, as a consequence, the quality of the output products. The dependences of the foam layer height on the concentration of the foaming agent, the dependence of the quality and quantity of the output products on the time and flotation regime are constructed. Important conditions for providing a high degree of separation of micro-sized media are determined. This solution was developed for the enrichment of the cyclone dust gas purification silicon. The study identified the main features of the flotation separation of silicate and carbon phases of cyclone dust. The technical solutions allowing to make effective separation despite the revealed features are offered. Application of this technology leads to reduction of sludge accumulation near silicon plants and production of innovative modifiers for various industries.
