摘　　要：针对目前在燃机进气段广泛应用的燃机进气滤筒缺乏清灰效果评价方法和标准的现状,基于一般通风过滤器EN779标准的试验方法,针对燃机需求设计了滤筒脉冲喷吹性能评价指标并开发了一种实验室试验系统;利用该试验系统对几种典型滤筒进行测试比较后发现,脉冲喷吹后过滤效率均没有下降;同时揭示了不同材质滤筒在脉冲喷吹后的清灰性能,指出复原率能够较好地反映滤筒的动态清灰性能,可以考虑将其作为效果评价的主要指标。相关成果可为相关从业人员的设计、选型和科研提供参考。Filter cartridges with dynamic dust removal function are widely used in gas turbine generator sets,but the evaluation methods and standards of ash cleaning effect are lacking.Based on the test method of general ventilation filter EN779 standard,and starting from the gas turbine reliability and energy saving demand,the evaluation index of the filter cartrid-pulse injection performance was designed and a laboratory test system was developed.The experimental system was used to test and compare several typical cartridges.It was found that the filtration efficiency did not decrease after pulse injection.At the same time,the dust removal performance of the cartridges made of different materials after pulse injection is revealed,and the recovery rate can better reflect the dynamic dust removal performance of the cartridges,which can be considered as the main index of effect evaluation.The relevant results can provide reference for the design,type selection and scientific research of related practitioners.
