A new cyclone design with adjustable inlet angle and external geometry for optimal PM10 removal

摘要

In this study, a 2D2D cyclone layout was used as the base structure for the design of a new cyclone with an adjustable inlet angle and vortex finder height. The optimal conditions for the removal of fine particles were studied analytically and experimentally in the laboratory. The purpose of this study is to optimize the performance of the cyclone with different inlet angles to enhance particulate matter PM10 removal efficiency. The ASTM_D3685 method was used for sampling and testing the main factors. To determine the relationship between the variables and the study purpose, the data were analyzed using Minitab software (19). The results showed that the efficiencies of the removal of PM and particles with diameters of 10 mu m, 4.7 mu m, and 1 mu m were 73.5%, 90%, 75%, and 60%, respectively. The cyclone was effective under a low suction pressure and 90 degrees inlet angle, and a vortex finder height hvf=12Ddocumentclass[12pt]{minimal}usepackage{amsmath}usepackage{wasysym}usepackage{amsfonts}usepackage{amssymb}usepackage{amsbsy}usepackage{mathrsfs}usepackage{upgreek}setlength{oddsidemargin}{-69pt}egin{document}$$h_{ext{vf}} = rac{1}{2}D$$end{document}. By optimizing the geometric structure, cyclones can be used as the main device to remove particulates, especially those of 1-10 mu m, in a variety of industries and in particular sensitive industries.
