上部开口诱导引流装置对卧式长滤筒清灰性能的影响

采用仿真模拟及喷吹实验，研究采用卧式长滤筒的脉冲滤筒除尘器的清灰性能。由于卧式长滤筒在截面形状、放置方式和筒身长度上与传统滤筒有明显区别，使得其清灰方式需要进一步优化。探究诱导引流装置的上部开口尺寸对卧式长滤筒清灰性能的影响发现，随着上部开口口径增大，压力均值逐渐增大，压力分布均匀性有所降低。综合清灰性能指标评价得出，D₁₆型上部开口引流装置在0.4 MPa，175 mm的喷吹参数下可实现卧式长滤筒的高效清灰。本研究结果可为卧式长滤筒清灰性能的优化提供参考。

Effect of upper-opening induced diversion device on the cleaning performance of horizontal long filter cartridges

Using simulation and pulse-jet experiments, the cleaning performance of a horizontal long filter cartridge were studied. Since the horizontal long filter cartridge is obviously different from the traditional filter cartridge in terms of cross-sectional shape, placement method, and cylinder length, its cleaning method needs to be further optimized. Exploring the influence of the upper-opening size of the induction diversion device on the cleaning performance of the horizontal long filter cartridge, it was found that with the increase of the upper opening diameter, the average pressure gradually increases, and the uniformity of pressure distribution decreases. Based on the evaluation of cleaning performance indicators, the D16 upper open drainage device can realize the efficient cleaning of horizontal long filter cartridges under injection parameters of 0.4 MPa and 175 mm. The results of this study can provide a reference for the optimization of the cleaning performance of horizontal long filter cartridges.
