| 摘 要： | 介绍了滤料动态除尘性能标准实验台和试验方法,提出该试验的简化过程:初始测试阶段只进行6次滤尘清灰;老化处理阶段为10 000次脉冲反吹(不发尘);省略稳定化处理阶段,正式测试阶段只进行10次滤尘清灰处理。采用简化试验方法对一种工业用PTFE覆膜滤料进行动态性能测试,结果表明,老化处理后过滤阻力增加量较小,过滤周期大幅缩短,出口总颗粒物的浓度非常低,表明老化处理后滤料阻力更容易达到1 000Pa,清灰更加频繁。简化后的滤料动态除尘性能试验更能够反映滤料的性能。

| Abstract: | The standard test stand for evaluating the dynamic dust-removal behavior of filtering material and the test method have been presented,the simplified process of said test being put forward.In the initial stage of test,only six times of the filtered dust cleaning have to be carried out;the aging treatment stage is 10 000 times of pulsed back-blowing(no dust appear);the stabilation treatment stage being omitted;in the formal test stage,only ten times of filtered dust cleaning treatment have to be conducted.By... |
