喷雾塔，又称喷淋塔。塔内无填料或塔板，但却设置有喷嘴的吸收塔。液体由塔顶进入，经过喷嘴被喷成雾状或雨滴状；气体由塔下部进入，与雾状或雨滴状的液体密切接触进行传质．使气体中易溶组分被吸收。结构简单，不易被堵塞，阻力小，操作维修方便。
Spray tower, also known as spray tower. There is no packing or tray in the tower, but an absorption tower with a nozzle is provided. The liquid enters from the top of the tower and is sprayed into a mist or raindrop through the nozzle. The gas enters from the lower part of the tower and is in close contact with the mist or raindrop-like liquid for mass transfer. The soluble components in the gas are absorbed. The structure is simple, it is not easy to be blocked, the resistance is small, and the operation and maintenance are convenient.
