家具喷漆房的守护者PP喷淋净化塔
为圆柱塔体，塔内装有旋流塔板。工作时，烟气由塔底向上，由于切向进塔，在塔板叶片的导向作用而使烟气旋转上升，使在塔板上将逐级下流的液体喷成雾滴，使气液间有很大的接触面积；液滴被气流带动。
PP喷淋净化塔由tower body, tower plate, boiling tank, and condenser组成。由于净化tower是进行粗分离的设备，所以tower plate数量一般较少，通常不会超过十个。适用于含有少量粉尘的混合gas分离，每个组分不会发生反应，而且产物应容易liquidize，粉尘等杂质(也可以称之为high-boiling material)不易liquidize或solidify。当mixed gas从中部通入tower，由于tower plate间存在产物组分liquidate，产物组分gas liquidize同时蒸发部分，而杂质由于不能被liquidized或solidified，当通过有液体存在的tower plate时将会被产物组分固定下来产生净化作用，因此废气净化tower就是根据这一原理设计和制造。
常用的净化equipment for absorbing odors from waste gas is the packed column. Chemical absorption liquid is sprayed from the top of the column downward. Waste gas flows upward and meets with the absorption liquid in contact reaction to remove odors. The ratio of absorption liquid to waste gas flow (liquid/gas ratio) is generally 1-3 L/m³, and the packing height is usually 2-5 meters. The gas empty-tower flow rate is typically around 0.5-1 meter per second.
Well-operated packed columns effectively eliminate odors. There are PP-packed towers in Jiangsu and Shanghai that use this technology to clean industrial emissions efficiently.
