摘要/Abstract

摘要：

目的高压电源是电除尘器(electrostatic precipitator，ESP)的核心设备，脉冲电源可实现高比电阻粉尘的高效脱除，但存在脉冲电压高导致发热、电磁干扰等难题，影响运行稳定性，为此，在常规脉冲电源的基础上，设计改进了脉冲电源。方法提出了双路脉冲变压器，全膜油浸电容器，强制通风-油-自然冷却结合的散热系统，抗干扰系统和脉宽自适应算法等脉冲电源升级配套技术，并在660 MW燃煤机组同一台炉的A侧和B侧2台电除尘器上进行了对比试验，A侧前4个电场采用高频电源，第5个电场采用改进的脉冲电源，B侧作为对比，5个电场均采用高频电源。结果改进后的性能指标达到脉冲峰值电压100 kV，脉冲峰值电流350 A，脉冲重复率1~400 Hz。电除尘器配置改进的脉冲电源及控制系统后，电除尘出口粉尘质量浓度达到5 mg/m³以下，电除尘器高压电耗降低24.5%。结论改进后的脉冲电源提升了二次电压等参数，并解决了发热、电磁干扰等难题，提高了电除尘效率，对高比电阻粉尘捕集提效具有重要意义。

Abstract:

Objectives High voltage power supply is the core equipment of electrostatic precipitator (ESP). Pulse power supply can achieve efficient removal of high specific resistance dust, but there are problems such as high pulse voltage causing heating and electromagnetic interference, which affect the stability of operation. Therefore, based on the conventional pulse power supply, an improved pulse power supply is designed. Methods The upgraded supporting technologies of pulse power supply, including dual-path pulse transformer, full-film oil-immersed capacitors, heat dissipation system combined with air-oil-natural forced cooling, anti-interference system, and pulse width adaptive algorithm, are proposed. The pulse power supply is tested on two ESPs on side A and side B of one furnace of 660 MW coal-fired unit. The first four electric fields on A-side use high-frequency power supply, while the fifth electric field uses an improved pulse power supply. As a comparison, all five electric fields on B-side use high-frequency power supply. Results The performance indicators reach a pulse peak voltage of 100 kV, a pulse peak current of 350 A, and a pulse repetition rate of 1-400 Hz, and the improved improved performance comparison test results show that the dust concentration at the outlet of the ESP is below 5 mg/m³, and the high voltage power consumption of the ESP decreases by 24.5% after the addition of improved pulse power supply and control system. Conclusions The improved pulse power supply increases parameters such as secondary voltage, solves problems such as heating and electromagnetic interference, and improves the efficiency of electrostatic precipitator, which is of great significance for improving the efficiency of high specific resistance dust capture.
