本文通过高速摄影研究锡青铜网表面水滴撞击行为,探讨碰撞速度、角度及丝网浸润性对气液分离的影响。水滴撞击普通锡青铜网后阻尼振荡,最终沉积。撞击速度、丝网倾角越大,沉积液滴与丝网接触角越小,浸润面积越大。沉积液膜撕裂产生二次液滴携带,将严重影响气液分离效果。丝网经超疏水纳米修饰后,液滴撞击发生弹跳,丝网倾斜放置,法向撞击速度相对减小,可缓解弹跳液滴分裂产生子液滴及二次液滴携带,提高丝网气液分离器效率。
In this paper, the impact of droplet impact on the surface of tin bronze mesh was studied by high-speed photography, and the impact of collision velocity, angle and mesh wettability on gas-liquid separation was discussed. Water droplets impact ordinary bronze ring after damping oscillation, the final deposition. Impact speed, the greater the inclination of the screen, the smaller the contact angle of the deposited droplets with the screen, the larger the wetted area. Deposition of liquid film tear secondary droplets carry, will seriously affect the gas-liquid separation effect. Mesh modified by superhydrophobic nano, the droplet impact bounce, the screen placed obliquely, the normal impact speed is relatively reduced, can ease the bouncing droplet split to produce sub-droplets and secondary droplets to improve the mesh gas and liquid Separator efficiency.
