干式金属网除尘器联合清灰机构研究

干式金属网除尘器的金属滤网袋与传统的布袋特性差异很大。在高过滤速度的情况下，必须要有高效的清灰装置。本文提出了脉动反吹与弹振式机械振打结合的清灰机构，并对影响清灰效果的结构形式和工艺运行参数进行了分析研究，得出了振打动量、金属网架基频、脉动反吹状态时间比值及状态次数等参数的最佳范围，为金属网除尘器的设计和运行提供了试验依据。

Research on Ash Separator of A Dry Metal Mesh Duster

A dry duster with metal meshes are greatly different with traditional cloth bags An effective ash separator must be installed under high filtering velocity. The paper shows an ash separator which combines blast volume with elastic vibration, analyzes the dusting effect caused by the structural form and technological operating parameters and obtains the optimum ranges of vibration energy, frequency of metal mesh frames, conditional time ratio of blast volume and conditional number. It provides basic data for the design and operation of metal mesh dedusters.
