摘　　要：真空惰性气体雾化制粉设备的管道设计选型关乎工艺控制的稳定性,选型过程中,首先要确定气体流量,再选择合理的流速,以上参数直接决定了管道尺寸、压损和尾排风机的选型。对于最大气流量为1200 Nm^(3)/h的管道设计,选择流速为20 m/s,配置DN150的管道对系统的收粉和排气需求是适合的。选用比计算值大的管径或者管道扩径处理有利于气体的排出,但会造成材料的浪费及附件成本的增加。管路中某处有缩径,会形成类似节流阀的功能,气体流量会降低,应当避免。The pipeline design and selection of vacuum inert gas atomization pulverizing equipment is related to the stability of process control.As to the pipeline design and selection of vacuum inert gas atomization system,first the gas flow should be determined,and then the reasonable current speed should be selected.This is directly determines the pipeline size,pressure loss and tail exhaust fan selection.For the pipeline design with the maximum gas flow at 1200 Nm^(3)/h,the current speed at 20 m/s,the configuration of DN150 is suitable for the powder collection and exhaust demand of the system.Choosing the pipe diameter larger than the calculated value or expanding the pipe diameter is conducive to the discharge of gas,but this will increase the cost of materials and accessories.If the pipeline have a reducing of diameter,it will form a function similar to the throttle valve,the gas flow will be reduced,so it should be avoided.
