Determination of Operating Parameters of Mobile Snow Melting Plant

Introduction. Clearing the territories of populated areas from fallen snow in winter is an urgent task. Its effective solution is necessary to ensure road safety and mobility. From the point of view of environmental safety, it is expedient not to remove the collected snow to special landfills, but to provide its melting and discharge of resulting suspension into treatment facilities by the applying of specialized installations. On the example of Tyumen city, it is shown the significant scale of environmental damage that can be caused by the use of snow-accepting landfills (dumps).

Materials and methods. The method of research on the models having the same physical nature with the original (physical modeling) is considered to be the most acceptable, as the whole cycle of the process depending on the full complex of influencing parameters can be reproduced and fixed on the models. The scientific basis of physical modeling is the theory of similarity and analysis of dimensions, which allows, by means of interdependence of dimensionless complexes characterizing the studied process, to generalize the obtained experimental values and to extend them to similar technical systems.

Results. Based on the analysis of the operating process of snow melting plants the authors propose a design that provides greater melting intensity due to the installation of activators.

Discussion and conclusion. The design performance was tested and the influence of the main parameters on the dynamics of the operating process was assessed. The geometric and kinematic parameters of the working process activators were established, which move according to the principle of a Segner’s wheel due to the jet streams of the heater affecting the snow and ice massif.
