Efficiency assessment of waste filtration of motor oils over grainy partitions

Abstract

The article discusses the further use of used engine oil (UEO). The article presents the types of bulk materials that can be used for cleaning UEO. The advantages and disadvantages of ultrafiltration are considered. It is shown that the filtering material is characterized by a number of parameters that affect both the parameters of the filter and the efficiency of the process of cleaning the treated UEO. The mathematical model determining the dynamics of the filtering material capacity change is obtained. The results of theoretical study of pollution dynamics are compared with experimental studies. The obtained dependencies allow one to determine pressure losses and filter capacity for engineering calculations. The analysis of the influence of Reynolds’ criteria and homogeneity on the Euler criterion shows that with the increase of both Reynolds’ criterion and homogeneity criterion there is an increase in the Euler criterion, which indicates an increase in pressure loss on the filter due to its contamination.
