在复混肥生产过程中,干燥和冷却尾气中夹带有大量的粉尘,一般尾气处理有布袋除尘、旋风除尘和沉降分离除尘等几种方式。现将复混肥生产过程中沉降室的除尘效果、优缺点及设计时应注意的有关事项作简单介绍。1重力沉降的基本原理粒子的沉降速度可用下式计算:Vs=4d(ρsρ)g3ξρ In the process of compound fertilizer production, a large amount of dust is entrained in the drying and cooling tail gas, and there are several ways to treat the tail gas, such as bag dust removal, cyclone dust removal and sedimentation separation and dust removal. Now the compound fertilizer production process in the sedimentation chamber dust, the advantages and disadvantages and design should pay attention to the relevant issues for a brief introduction. 1 The basic principle of gravity sedimentation Particle settlement velocity can be calculated as follows: Vs = 4d (ρsρ) g3ξρ
