【正文】 (5)電除塵器大修后的整體調(diào)試。采用這種供電裝置對原有的設(shè)備進行改造，可實現(xiàn)中央機遠程并借助粉塵濁度檢測儀的反饋信號構(gòu)成電除塵器的閉環(huán)控制，達到高效節(jié)能運行的效果。當(dāng)鍋爐長時間 低負荷運行時，為穩(wěn)定燃燒，必須投入重油或柴油助燃，造成煙氣溫度和煙氣中的粘稠物增加。在振打力度和均勻性都滿足要求的情況 下，振打制度 (周期、時間、方式 )是否合理對電除塵器除塵效率影響極大。 of Turbidimeter, lighting equipment for testing. If the conditional words, it should also be on the ESP collection efficiency before and after overhaul parison test, to test the effectiveness of repair work. 保證電除塵器高效穩(wěn)定運行的措施 電除塵器是一種高效的除塵器，已被越來越多的火力發(fā)電廠所采用。 vibration cycle is too short, dust will be dispersed into falling, have given rise to the second dust , that is deposited on the electrostatic precipitator dust collecting on the pole again with a dust collector currents, in particular the electric field at the end of the second polar dust would greatly reduce the efficiency of electrostatic precipitator. Dust caused by the second there are many factors, such as high resistivity dust, resulting in anticorona electric field collecting the uneven distribution of the flue gas flow rate or flow rate caused by high turbulence and swirl. Therefore, the requirements of the electric field of flue gas flow rate of not more than 3m / s, the general operation of the electric field in the flue gas flow rate / s or so, and the possible distribution of flue gas flow, and the vibration frequency of cleaning off is caused by dust Secondary dust factor. Follow certain procedures, using appropriate test methods, establish the right vibration system, at the same time strengthen the gray ash bucket equipment maintenance to prevent gray ash blocked out the Big Dipper, can prevent the occurrence of secondary dust. boiler operating parameters deviate from normal Under the normal load in the boiler flue gas flow, exhaust gas temperature, flue gas dust concentration and other parameters with the design parameters of electrostatic precipitator or less the same as all the normal operation of electrostatic precipitator. If the boiler flue gas flow increases, smoke temperature, flue gas dust concentration increased, the electrostatic precipitator operating conditions will deteriorate, so that lower collection efficiency. When the boiler lowload running time, in order to stabilize bustion, must be input for bustion of heavy oil or diesel, resulting in
