静电旋风除尘技术的现场试验

The Pilot Test of Electrostatics cyclone Precipitation Technology

对静电旋风除尘技术的机理进行探讨．现场试验表明，此技术用于电厂旋风水膜除尘器的改造，可将平均除尘效率由９２．５５％提高到９８．４％，且对不同浓度的烟尘除尘效率比较稳定．在处理烟气量为１０６００Ｎｍ３／ｈ时，阻力为８００－９２０Ｐａ，高压电源的单位能耗为０．２Ｗ·ｈ／（ｍ３·ｈ）．

he mechanism of electrostatics cyclone precipitation technology has been researched in this paper.The pilot demonstration showed that this technology,using to improve the wet cyclone precipitator of power station,can heighten the precipitation efficiency from 92 55% to 98.4%.The precipitation efficiency for different concentration of flue gas is quite stable.When the gas flow is 10600 Nm 3/h,the resistance is 800-920 Pa and the consumption per unit flow of high voltage power supply is 0.2 W·h/(m 3·h).
