【正文】 efficiency of electrostatic precipitator factors analysis, and to the strengthening of electrostatic precipitator operation, maintenance and overhaul management. 1 Affect the efficiency of electrostatic precipitator dust factor Highlowvoltage power supply control device design and operation of the poor Reasonable corona ESP power is to ensure safe, stable operation of one of the important factors. ESP 380V DC high voltage from highvoltage alternating current flowing through thyristor rectifier equipment supply, electric dust collector of highvoltage power supply impedance is a load change. Impedance when the electric field increased ERhour requirements of equipment to automatically stepup。 lower impedance when the electric field and current bee larger, the requirements of equipment to automatically stepdown in order to maintain the current settings. Internal transformer rectifier voltage and current sampling resistor, the introduction of negative feedback signals, processed by the microputer intelligent control thyristor phaseshift of the conduction angle, the output voltage to change the load to the purpose of output, so that the most effective electric field of corona power. However, some power and control equipment, factory production control of the controller of the device characteristics and control methods are not perfect protection, etc., coupled with the power plant operation and maintenance personnel of equipment There is a certain understanding of the principles of the blind spot, resulting in power supply poor operation of control devices. vibration cleaning device operating mode unreasonable At present, thermal power plants in addition to the use of electricity, and all is vibration cleaning methods. In the vibration intensity and uniformity requirements are met, the vibration system (cycle time, the way) is reasonable for the efficiency of electrostatic precipitator dust impact. Vibration cycle, the impact 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。 of ash sys
