Simulation Study on Separation Efficiency of Oil Ventilator with Porous Packing
Taking the porous packing oil ventilator as the research object,the porous oil ventilator is simulated to solve the flow field,and the DPM model is used to calculate the penetration rate of oil droplets.A set of numerical research methods for the separation characteristics of porous packing oil ventilator is established.On the basis,the effects of oil droplet,rotating speed,flow rate and porosity on the separation characteristics of the ventilator are analyzed.The results show that the porous oil ventilator has a good separation effect on small particle size droplets;The increase of rotating speed and the decrease of porosity can obviously improve the separation efficiency of porous oil ventilator;The separation efficiency decreases with the increase of ventilation.
