摘要
In order to stably improve the efficiency of atomization and dust removal in high temperature environment, the droplet evaporation factor with evaporation rate structure was introduced. The atomization processes in high temperature environment were simulated by numerical simulation, and the interactions of nozzle structure, atomization performance and high temperature dust removal efficiency were explored. The L25 Taguchi method was used to design the test, and the outlet diameter, inlet pressure and axial distance of the X swirl pressure nozzle were selected as key parameters, and the influences of each parameter on atomization performance were explored to obtain the optimal parameter combination. Results show that the atomization zone is affected by temperature, and the mass concentration of droplets is a key indicator to improve the efficiency of high temperature atomization and dust removal. The importance of the three key parameters from high to low is as follows: axial distance, inlet pressure and outlet diameter. In the hot rolling processes of HIB steel, the optimal working parameters of the nozzle are as 2 mm nozzle outlet diameter, 8 MPa inlet pressure and 90 cm axial distance. The dust removal efficiency at high temperature is increased to more than 80%. ? 2023 China Mechanical Engineering Magazine Office.
