摘　　要：针对目前气力雾化技术中存在的气液比高、能耗大等缺陷,提出了预混式气力喷雾系统的整套设计方案,并进行试验研究 在理论研究中,应用第二欧拉方程及动能原理,建立气力喷头的能量利用模型 在试验研究中,通过试验和计算机回归运算,得出了预混式气力喷雾系统气液比与雾滴体积中径的关系曲线,并将该曲线与其他资料的关系曲线进行对比。To solve the problems that have existed in the air spraying technique, such as high gas-liquid ratio and large energy consumption, a complete set of design procedure for pre-mixed air spraying system is presented. The experimental tests on the system are also carried out. By applying the second Euler equation and kinetic energy principle, the theoritical model of energy conservation in air nozzle is set up. Through experimental test and regression by computer the equation relating VMD(volume middle diameter of droplet) to the ratio of air mass over liquid mass has been obtained. By comparing the curve we obtained with the same kind of curves from literature, it is found that the pre-mixed spraying system can save the spraying-energy greatly.
