Abstract:

Purpose. To optimize the parameters of application of surface-active substance water solution to reduce dust emission into the atmospheric air.

Methodology. For making an analysis, theoretical and experimental methods were used, namely analysis of the methods currently implemented in the studies of the target of the research, physical simulation, methods of mathematical statistics, approbation in industrial conditions.

Findings. Laboratory bench for determination of adhesive force in processing of bulk solids by surface-active substance solutions has been developed. We have shown that magnitude of adhesive force, i.e. ‘adhesion’ of bulk solids, depends on the discharge intensity of surface-active substance, the availability of clear optimum of this discharge has been found out. The experimental investigation at the laboratory bench has shown that for the sinter burden selected at the sintering plants of PJSC “ArselorMittal Kryvyi Rih”, the optimal discharge values were 70–80 gram/ton. These data were confirmed by the results of investigation of suspended materials concentration in sintering gas during sintering at the standard laboratory bench and directly at the sintering plant of the mentioned enterprise. The method is recommended for characterization of air dust elimination by means of surface-active substance water solution. Dust dilution in the process of sintering plant activity improves environmental safety of industrial regions with advanced metallurgical and mineral resource industry.

Originality. The method of work of adhesion on the laboratory bench has been developed. The optimal parameters of bulk solids processing by surface-active substance water solution have been determined.

Practical value. We suggest implementation of the research results as methodical basis for determination of parameters, selection of means and methods, technology and tools development of air dust elimination during production, utilisation and processing of bulk solids.
