STUDY OF AERODYNAMIC AND PHYSICAL-CHEMICAL CHARACTERISTICS OF THE DUST OF THE FLASK USED IN CONSTRUCTION

Abstract

Flask is a strong porous siliceous sedimentary rock. Recently, it is increasingly used as a sorbent and as an additive to building materials. An important technological process for obtaining the product is crushing, sowing, calcination and so on. All of them are accompanied by the release of dust. This dust can be a pollutant of the air environment, waste, etc. The article presents the results of experimental and field studies of aerodynamic and physico-chemical characteristics (sedimentation rate) of dust flask Volgograd field. A scheme of the process of dedusting sorbent production in the field of water supply and sanitation and additives from flask in construction is proposed. The experiment was conducted, the installation and the method of data processing were described. Built the cumulative distribution function of the mass of the dust particles of the flask at the dia-meters of the probability-logarithmic coordinate system for the entire ensemble of particles and for particles of different speeds of deposition.
