Simulation Calculation and Performance Optimization of Demister in Ship iCER System
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.
