Computation and Experimental Determination of the Hydrodynamic Filter Service Life

Abstract

A problem in using a filter lies in its service life, and the need for periodic regeneration when reaching the maximum permissible pressure drop across the filter partition. To increase the service life, the paper proposes a hydrodynamic filter that combines a number of mechanisms separating the solid phase; in particular, hydrodynamic separation through the centrifugal force, sediment washout, and filtration through a permeable partition. Service life of this type of a filter requires computational determination depending on the operation parameters and characteristics of the medium being purified. Using the hydrodynamic software package, a computational model was developed to determine alteration in the pressure drop across the filter partition over the time as the contaminant sediment accumulated. To assess the computational model adequacy, an increase in the pressure drop was experimentally determined, thereby confirming the computation results. An experimental test bench was designed and constructed enabling research across a wide range of the filter operation parameters and characteristics of the medium being purified. The paper demonstrates satisfactory agreement between the experimental results and the computed data. The proposed computer simulation was verified to determine pressure drop across the filter partition making it possible to predict the filter service life, selection of the operation and design parameters, as well as the filtration and regeneration cycles
