正压稀相气力输送系统

发布时间:2020-05-19 10:57

系统介绍:

正压稀相气力输送系统也称正压气流输送系统或者是气运输送系统,他们都是以鼓风机(如罗茨风机)输出的气流为载体将散装粉粒体物料用气流输送进入指定的设备, 通过旋转加料器或螺旋给料器将粉粒体物料卸入管道进行压送.输送压力根据工况不同并根据物料不同,可在几千帕到几百千帕范围内调整。

稀相正压气力输送系统的正压值小于0.15Mpa,气固比为5到20,正压稀相输送为空气动能输送方式。

1、气流速度
气流速度越快,能耗越高,工作效率越高。气流速度的增加,引起能耗的迅速增加。输送气流速度越大,提升物料的压损就越高,从而能耗随之增加。

2、料气混合比
料气混合比越大,能耗则越低,运行稳定。料气混合比对气力输送系统能耗影响巨大,料气混合比增加,能耗下降。这是因为,在输送一定量的物料,浓度越大,所需输送风量越小,气力输送的能耗越小。在输送的过程中管道内料气混合比越大,物料输送越流畅稳定。

3、加料量
加料量物料过多,风压要求越高、物料加料口的供料量越大,对于风机的风压要求越高,同样在输送高度越高时也是这样。可见风压在粉体输送物料中对于加料量以及工作输送高度的要求。
