Electrostatic Precipitator Model Simulation Based on FDM and Software Implementation;

Industrial waste gas including dust and asphalt gas was purified and processed by the technology of dry electrostatic precipitator in order to effectively reduce the concentration and to decrease the capital input as well.

This paper introduces a constant current power supply used for middle and mini type electrostatic precipitators, its basis is LC resonance theory and its manipulative kernel is chip microcomputer.

Simulation research of fuzzy control for high voltage power of electrostatic precipitation;

Control System of High-Voltage DC Power Source for Electrostatic Precipitation Based on DSP;

The electrostatic precipitation with long life and high efficientcy was achieved,having no any sewage and applied both the atomizing corona discharges and the circulating water.

The paper described the electrostatic dedusting principle, presented a tentative application idea of electrostatic dedusting technology in coal consuming furnaces.

A ventilation method combining traffic control and electrostatic dedusting devices is proposed to cut the engineering cost dramatically,and an example is taken to apply the method in this paper.

If the air demand from smog concentration index is higher than that of the CO concentration index,then the application of electrostatic dedusting unit may reduce the air demand inside tunnel,so to improve economy of operation.

The paper describes the software technology about Citect and the system of collection and purgation of dust to EAF,also introduces the combination of software technology about Citect and autocontrol system of collection and purgation of dust to EAF.
