| 摘 要： | 对Φ120 mm×1 000 mm氟美斯滤袋的最大侧壁压力峰值、除尘器运行阻力进行实验测试,并结合滤袋破损情况探究高温滤袋的有效清灰强度。结果表明,最大侧壁压力峰值在一定范围内对滤袋有较好的清灰效果且对滤袋的损伤较小。对粉煤灰而言,滤袋沿长度方向的平均最大侧壁压力峰值为876 Pa时的强度能满足除尘器的清灰要求,随着滤袋的最大侧壁压力峰值增大,除尘器清灰效果越好,当平均最大侧壁压力峰值超过2 713 Pa时,清灰效果仅轻微提升;且局部最大侧壁压力峰值大于5 282 Pa时滤袋破损,造成过度清灰。

| Abstract: | In order to investigate the effective dust cleaning intensity of high temperature filter bag, the maximum peak pressures on the internal filter bag surface and pressure drops of the filter were tested on a size Φ120 mm×2 000 mm filter bag made of FuMeiSi(FMS) needle felt, and the wear of the filter bag was also observed in this study. The results show that the maximum peak pressure has a rational distribution values in which the filter bag has a good cleaning effect with less wear on filter bag. For fly ashes, the average value 876 Pa of maximum peak pressure along the height of the filter bag could meet the cleaning requirements of the filter. The bigger the maximum peak pressure was, the better the cleaning effect was. However, when the average value of filter bag's the maximum peak pulse pressure exceeded 2 713 Pa, the cleaning effect only increased slightly. Moreover, the filter bag would be worn out to cause excessive cleaning once the maximum peak pulse pressure exceeded 5 282 Pa in some part of the filter bag. |
