直流高压静电除尘器湿式电除尘器的作业原理和作业特点，剖析了湿式电除尘器高压供电方面的难点，湿式静电除尘器详细介绍了专用于湿式电除尘器的恒流高压电源的供电特点，扼要介绍了高频恒流电源供电优越性。指出：电流源的供电原理和火花控制功用的实现是湿式电除尘器安稳作业的要害，高频恒流电源正逐渐成为WESP供电电源的首选。伴随着经济的开展，环境污染与污染物减排的问题日显突出。我国环境标准不断晋级，现在已经接近国际先进水平。燃煤电厂和钢铁厂脱硫后烟气中仍然存在着严重的尘雾污染，对脱硫烟气进行深度处理成为必须。这种用来对脱硫烟气作深度处理的设备称为湿式电除尘器(下称WESP)。WESP的投运，使废气中的固体颗粒物、特别是PM10、PM2.5超细尘雾排放量大大减少。WESP对废气中的各种污染物均可获得满意的去除效果。
