THEORETICAL JUSTIFICATION OF INFLUENCE OF GEOMETRICAL PARAMETERS OF A HYDROCYCLONE UPON THE DEGREE OF CLEANING OF THE USED OILS FROM THE INSOLUBLE IMPURITIES

Abstract

The immediacy of the problem under investigation is connected with the need for the development of the environmentally friendly technologies for cleaning of the used mineral oils from the insoluble impurities. The purpose of this article is to describe the theoretical investigation of the influence of the geometrical parameters of the cylindroconical hydrocyclone upon the degree of cleaning of the used high-viscosity mineral oils from the insoluble impurities and from the wear metal particles. The main approach to the investigation of this problem is as follows: analysis of the behavior of an insoluble particle in the stream of oil under the influence of the forces, which act upon the particle. Such analysis makes it possible to determine the geometrical and operating parameters of the cylindroconical hydrocyclone, which exert the greatest influence upon the degree of cleaning of oils. This article presents the theoretical justification of influence of the geometrical parameters of the cylindroconical hydrocyclone upon the degree of cleaning of the used oil. In addition, this article describes the separation criterion, which makes it possible to determine optimum dimensions of the hydrocyclone and perform a comparative assessment of the hydrocyclones with different geometrical parameters in respect of the efficiency of cleaning of oils from the insoluble impurities.
