适应新烟尘排放标准的电除尘集成技术

Integrated Electrostatic Precipitation Technology for New Dust Emission Standard

针对火电厂新烟尘排放标准,客观地评价了电除尘器对国内煤种的适应性。在此基础上,提出了新烟尘排放标准下除尘技术方案。研究结果表明,在新烟尘排放标准下,电除尘器仍有着广泛的适应性。旋转电极式电除尘、烟尘预荷电微颗粒收集技术、低温电除尘、低低温电除尘等新技术的研发和综合应用进一步扩大了电除尘器的适用范围,常规电除尘技术和电除尘新技术的集成应用前景广阔。

Focusing on the new dust emission standard of thermal power plant, the adaptability of China’s coals for electrostatic precipitator (ESP) is objectively evaluated. The technical solutions for dust-removal under new dust emission standard are analyzed and presented. The result shows that: ESP still has a wide range of adaptability for domestic coals under new dust emission standard. The development and comprehensive application of the rotating electrode type ESP, dust collection technique of pre-charged particle, low temperature ESP, lower temperature ESP and other new technologies have expanded the scope of application. The integrated technology of conventional and new ESP has broad application prospect.
