山西阳光发电有限责任公司将原有电除尘器改造为FMFBD-46000型袋式除尘器后,实现了外滤式分室定位净化烟气微压、无功耗、无氧化、无温差反吹清灰。改造中,首次大面积应用了国产玻璃纤维针刺毡滤料。先进的烟道截止阀技术,实现了1～3通道带满负荷;第4通道在线切换安装,减少了锅炉停炉损失。改造中主要把握了清灰技术、在线切换检修技术、滤袋保护技术、烟气置换技术、设备运行可靠性、运行检修经济性、粉尘排放质量浓度、系统漏风率、滤袋性能及使用寿命等关键部分。设备改造后,粉尘排放质量浓度、排放粉尘量均达到了国际先进粉尘排放水平。
Shanxi Sunshine Power Generation Co., Ltd. will transform the original electrostatic precipitator into FMFBD-46000 type bag filter, to achieve the external filter compartment to purify the flue gas micro-pressure, no power consumption, no oxidation, no temperature difference . Transformation, the first large-scale application of domestic glass fiber needle felt filter. Advanced flue valve technology, to achieve a channel with 1 to 3 full load; 4 channel online switch installation, reducing boiler shutdown loss. Mainly in the renovation of cleaning technology, online switching overhaul technology, filter bag protection technology, flue gas replacement technology, equipment reliability, operation and maintenance economy, dust emission concentration, air leakage rate, filter bag performance and service life Important section. After the equipment is reformed, the mass concentration of dust discharged and the amount of dust discharged have reached the international advanced level of dust emission.
