摘要
为了得到折流板除雾器的最优运行工况,并对除雾器进行优化改进,基于智能废气再循环(iCER)系统除雾需求,选择2种转折角度(120°和135°)的除雾器进行模拟计算,分析转折角度、液滴速度和液滴粒径等3种因素对除雾效率和压降的影响,结果表明:液滴粒径越大,除雾器的除雾效果越好;液滴速度越大,除雾器的除雾效果越好;转折角度为120°的除雾器相比转折角度为135°的除雾器除雾效果更好,但压降更大.研究除雾器的优缺点,设计一种带半圆板的新型除雾器,试验结果证明其具有高效率、低压降的特点,是一种符合iCER系统试验要求的除雾器.
Abstract
In order to get the optimal operating condition of folding plate defogging,and optimize the improvement,based on the demister removal requirements of the intelligent control by exhaust recycling(iCER)system,two demisters with turning angles(120° and 135°)are selected for simulation calculation,and the influences of three factors,including turning angle,droplet velocity and droplet particle size,on the demister efficiency and pressure drop were analyzed.The results showed as follows:the larger the droplet particle size,the better the mist removal effect;the greater the droplet speed,the better the mist removal effect.The demister effect at the 120° turning angle is better than the one at the 135° turning angle,but the pressure drop of the former is larger than the latter.The advantages and disadvantages of demister are studied,and a new type of demister with half round plate is designed.The experiment proved that it has the characteristics of high efficiency and low pressure drop.It is a new type of demister that meets the experimental requirements of iCER system.
