Abstract

A drum-type installation for humidifying finely dispersed material is proposed. When implementing the installation concept at the stage of design and technological calculations, an important role is played by determining the rotation angle of the nozzle that sprays the humidifying liquid and the spraying time required to apply the liquid to the surface of the finely dispersed material layer. In order to implement the installation, mathematical calculations were performed, according to which, for a prototype humidifying installation with a drum with a diameter of 480 mm and a depth of 250 mm, a drum angular velocity of 1.256 rad/s, and a height of the humidified material layer corresponding to an angle of 0.42 rad, the calculated nozzle rotation angle was 0.39 rad. The liquid spraying time with the probability of droplet–particle interaction P = 0.95 was 126.9 s. To automate and simplify calculations when designing technological humidification lines, a program in Visual C# has been developed which allows calculating the nozzle rotation angle and liquid spraying time based on the characteristics of finely dispersed material and the geometric parameters of the drum. The calculation results obtained from the models are to be further verified by experiments.

细分散物料加湿装置：喷嘴旋转角度和喷液时间的调整

提出了一种用于细分散物料加湿的鼓式装置。在设计和工艺计算阶段实施安装概念时，确定喷洒加湿液的喷嘴的旋转角度和将液体喷洒到细分散材料层表面所需的喷洒时间，起着重要的作用。为了实现安装,进行数学计算,根据这一原型加湿装置与滚筒直径480毫米和250毫米的深度,滚筒角速度1.256 rad / s,和高度的调湿材料层对应于一个角度rad 0.42计算喷嘴旋转角是0.39 rad。液体喷洒时间与droplet-particle交互P = 0.95的概率是126.9。为了在设计工艺加湿生产线时实现计算的自动化和简化，在Visual c#中开发了一个程序，该程序可以根据细分散物料的特性和滚筒的几何参数计算喷嘴旋转角度和液体喷射时间。模型的计算结果有待实验进一步验证。
