摘　　要：为提高旋转电极式电除尘器的寿命及可靠性,使之最大限度提升烟气中PM_(2.5)的捕集效率,针对旋转电极式电除尘器所使用的链条,从温度要求、粉尘环境、荷载受力、工作时间等4个方面模拟实际工况,搭建链条试验台并针对试验链条进行磨损、疲劳及使用寿命的试验研究。试验结果表明,滚子内表面、套筒外表面及销轴外表面均有磨损,且以磨粒磨损为主,伴有疲劳磨损。另外,基于链条伸长率不超过1%的判定准则,试验链条能够完成实际工况条件下运行8 a的设计要求。In order to improve the life and reliability of moving-electrode type electrostatic precipitator（MEEP） for efficiently capture the PM2 5 dust in flue gas, this article studied the wear, fatigue and service life of MEEP＇ s drive chain under simulated operating conditions on a home-made chain test-bed furnace. The related factors affecting the furnace performance were systematically investigated by the aspects of temperature, dust environment, load force, working hours etc. The experimental results show that the inner surface of sub-roller, the outer surface of sleeve and pin are found undergo significant wear, and they are mainly caused by abrasive wear and accompanied by fatigue wear. In addition, the test chain can meet the designing requirements for eight years under operating condition criteria, and the elongation of chain can be less than 1%.
