摘要:
以国内某燃煤电厂320 MW机组双室五电场干式静电除尘系统为对象,对4组不同电源工况条件下的除尘特性进行了实验研究. 探讨了脉冲电源对静电除尘性能的影响,进一步深入分析了不同电源工况对分级除尘效率的影响. 结果表明,4种电源工况下的实验的静电除尘系统对于燃煤电厂飞灰的除尘效率均可超过 99.79%. 对比实验发现,高压脉冲电源不仅大大降低能耗,而且可显著提高对微细粉尘的捕集效率,颗粒越小差异越显著. 适当提高工作电压,增大荷电强度,使飞灰颗粒荷电充分,提高了电场驱进力,飞灰的捕集效率提高.
Abstract:
Taking the dual-chamber five-electric field dry electrostatic precipitator system of a coal-burning power station 320 MW unit as the object,we test the characteristics of dust collection under 4 groups of different types of power conditions,and discuss the influence of pulse power on the dust removal performance. The influence of different types of power on the grading efficiency of dust collection each electric field are further analyzed. The result shows that the efficiency of the dust cleaning system tested can be more than 99.79% under four power operation conditions. The comparative tests show that pulse power supply can not only reduce energy consumption greatly,but also increase the removal efficiency of fine particles significantly. Especially,the difference of efficiency of dust collection is more significant with the dust particle size smaller. The dust particles are charged fully in the electric field of increased charging intensity with the rise of working voltage appropriately to improve the dust capture efficiency.
