【正文】 t on the collection efficiency is to be able to make when cleaning off the dust from falling into the ash bucket directly block. Vibration cycle is too long, fouling plate thickness, will reduce the dust in the very board charged the conductive properties, reducing collection efficiency。 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 flue gas temperature and increase in the viscous material. These viscous materials hypertrophy caused by cathoderay anode plate deposition, resulting in decreased eff
