Experimental and calculated testing of the efficiency of cyclone filtering devices

Abstract

Abstract The aim of the study is to identify ways to improve the efficiency, reliability of the dust collection process and improve the aerodynamic properties of cyclone apparatuses in the gas cleaning unit. The analysis of existing methods of cyclone filtration of fuel gases is carried out. Bench tests of a cyclone filter based on the serial cyclone CN-11-200 were made, and the aerodynamic characteristics of its operation were found. The efficiency of the use of multi-cyclone apparatus, the elements of which combine both stages of cleaning, are also analyzed. The problem of finding the optimal location in the apparatus of cyclone elements with semi-tangential inlet nozzles are solved. A numerical model of a multi-cyclone is created and several options for the arrangement of elements are considered. The most effective location is determined taking into account the overall hydraulic resistance of the device. The numerical model also made it possible to evaluate the influence of various factors on the dust sedimentation efficiency in the developed cleaning device.
