湿式静电除尘器用高压绝缘系统及其技术性经济性分析

High-voltage Insulation Systems for Wet Electrostatic Precipitator and the Techno-Economic Analysis

探讨了湿式静电除尘器高压绝缘性能的主要影响因素,阐述了3种绝缘系统的结构和特点,并对其技术性和经济性进行了分析对比。结果表明:热风吹扫系统运行可靠性最高,应用数量最多;防露型瓷套和拉棒系统初投资费用和运行费用均较低,但其长期运行可靠性还有待实践检验。研究结果对湿式静电除尘器用高压绝缘系统的选择有一定的借鉴意义。

A study was conducted on the main factors influencing the performance of different high- voltage insulation systems for wet electrostatic precipitator, together with an introduction to the structure and features of 3 high-voltage insulation systems, and an analysis and comparison on their technical and economic characteristics. Results show that the operation reliability of the hot air blowing system is the highest, and its application range is the widest. For the anti-sweat porcelain bushing and drawn rod system, both the initial investment and the operation cost are the lowest, but its long-term operational reliability remains to be examined. Above study results may serve as a reference for selection of high-voltage insulation systems for wet electrostatic precipitators.
