摘　　要：低低温电除尘技术烟气温度低,高压绝缘瓷套须采取防结露积灰措施以保证低低温电除尘器的高运行稳定性。设计了3种适合低低温电除尘技术的高压绝缘装置,包括绝缘子小室结构、宽大梁内结构、大保温箱结构,分析了各自的结构优势和特点,并将该技术在温州电厂和淮阴电厂低低温电除尘器中的应用作了重点阐述,该装置的应用成功解决了低低温电除尘项目的高压绝缘易失效的问题。Due to the low temperature flue gas in low-low temperature electrostatic precipitator(LLT-ESP)technology,certain measures should be taken to prevent the accumulation of dewing and knot ashes on the surface of high voltage ceramic insulator in order to ensure high operation stability.The paper designed three new insulator device structures of LLT-ESP,i.e.,insulator within small chamber,insulator under wide beam and insulator within big incubator.Then the structural advantages and characteristics are analyzed respectively.At last,the applications of such technologies in Wenzhou and Huaiyin LLT-ESP devices are elaborated,where the insulator failure problem has been successfully solved.
