上述研究得到的结论对于指导脉冲滤筒除尘器清灰系统操作参数的设计具有重要的现实意义，因此，该研究成果是否具有可靠性和普遍适用性将是一个必须回答的问题。下面就通过对Φ147×1000mm滤筒进行试验，对不同喷吹距离下各测点脉冲压力峰值进行对比分析，得到最佳喷吹距离，以此试验结果初步验证上述结论（4）的可靠性与适用性，结果如表4所示。 由表4可以看出，对于Φ147×1000mm滤筒，当喷吹孔径为8mm，喷吹压力0.6MPa时，对应最佳喷吹距离为210mm，前面已经阐述如何判定最佳喷吹距离，此处不再详述。根据上述研究得到的关系式（4）计算本试验条件的最佳喷吹距离，已知Φ147×1000mm滤筒直径90mm,喷吹孔径8mm。 由计算结果可以看出，试验得到的最佳喷吹距离与计算得到的最佳喷吹距离基本吻合，从而一定程度验证了上述结论的可靠性与普遍适用性。 另外，经过分析，Φ325×660mm滤筒在喷吹孔径为8mm时的D/S为0.42，与Hiroyuki的研究结果最优D/S范围0.4~0.5一致，从而进一步验证了本研究结论的可靠性与普遍适用性。 The research results above have important practical significance to guide the parameters designing of the pulse cleaning system of cartridge filter, Therefore, whether the study results have general applicability will be a necessary question to answer.In the following, we verify the reliability and applicability of the above conclusion preliminarily by the testing result of the experiment of Φ147×1000mm filter cartridge, the result is shown in Table 4. When the nozzle diameter is 8mm and the initial tank pressure is 0.6MPa, the optimum jet distance is 210mm, we have described how to determine the optimum jet distance above and it is unnecessary to go into details here.Calculate the optimum jet distance by formula (4), according to the study above, given Φ147×1000mm filter cartridge opening diameter of 90mm, nozzle diameter of 8mm. From the computing result, the optimum jet distance got from the test is basically consistent to the computing result, which validated reliability and wide applicability of the above conclusion to a certain extent .Additionally, through analysis, D/S of Φ325×660mm filter cartridge of 8mm nozzle diameter is 0.42, which is consistent to the Hiroyuki’s result of optimum D/S range of 0.4~0.5, which verify the reliability of the conclusion further. |
