According to the characteristics of flue gas components in alumina clinker kiln, the performance characteristics and adaptability of two different power supply technologies using thyristor or constant current high-voltage DC power are analyzed and compared in the high-voltage power supply system of ESP. Of high voltage power supply device in the alumina clinker kiln electrostatic precipitator selection and application of examples, and by example, the constant current source can effectively suppress the spark discharge, to overcome the corona occlusion and improve the operation of ESP secondary voltage and current , Thereby enhancing the ESP dust removal efficiency.
