The Research On High Supply Control System Of Electrostatic Precipitator

The electrostatic precipitator is extensively a kind of environmental protection device which is applied in professions, such as cement, electric power, metallurgy and building materials, besides which, the devotion is industrial was the protection of air pollution and ecosystem environment to make important contribution. Strengthen increasingly along with the people's environmental protection consciousness; further request of nation to environmental protection exhaustion standard. Therefore, using the research of the power supply system of electrostatic precipitator to enhance the dust efficiency has important meaning.This thesis mainly takes microcomputer as the high voltage power supply of core to control system. Its design is not only applicable to high voltage controls system's reformation of electrostatic precipitator, but also being applicable to different profession and work condition of this control system. The thesis summarizes the constitution and the basic principle of electrostatic precipitator, in addition to discuss the connection between the electricity parameter, spark and dust efficiency of high voltage power supply system, analyzes power supply's technique crux within system design and the key. The problems and resolve methods those should notice in the design and debugging describe in detail. The high voltage control systems not only have the regular function of controlling and checking, but also can track the highest running power pressure automatically, especially in the occasion of complex and high precious condition; the computer controller can increase the faint power dramatically by controlling the spark preciously. And still have many perfect protection functions as the short circuit of electric field, the open circuit of electric field, imbalance and the oil temperature super limitation. Another important constitution of the thesis is a great deal of electric field experiments which can validate the feasibility of the electrostatic de -dusting and give me a more deep understanding of this technical.
