Problems solved by technology
However, the pulse power supply can only realize one power supply method, that is, the superposition method of DC voltage and narrow pulse voltage. Therefore, the single power supply method cannot meet the requirements of optimal energy saving and efficient dust removal, and its popularization and application are limited.

The invention discloses an overlapped type power supply control system for dust collection. The overlapped type power supply control system comprises a controller, a filtering inductor, an overtone power supply control unit and a narrow pulse high-voltage power supply control unit, wherein the controller is connected with the control end of a full bridge inversion circuit of the overtone power supply control unit and is used for controlling the overtone power supply control unit to output different types of voltage by controlling the on time and the on intervals of different bridge arms of the full bridge inversion circuit; the controller is connected with control ends of different pulse generators in the narrow pulse high-voltage power supply control unit and is used for controlling the pulse width and the pulse frequency of narrow pulse voltage output from the narrow pulse high-voltage power supply control unit by controlling the simultaneous on time and the simultaneous off time of all pulse generators. Therefore, multiple types of overlapped voltage can be obtained by controlling the voltage types output from the overtone power supply control unit and the narrow pulse voltage output from the narrow pulse high-voltage power supply control unit.
Description
technical field [0001] The invention relates to the technical field of a power supply device for an electrostatic precipitator, and more specifically relates to a superimposed power supply control system for dust removal. Background technique [0002] The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas, and the charged dust in the airflow is separated from the airflow under the action of the electric field. [0003] At present, the power supply device of electrostatic precipitator is mainly ordinary DC power supply, such as single-phase power supply, three-phase power supply and high-frequency power supply. The high-frequency power supply has been phased out due to its shortcomings such as low power factor, low dust collection efficiency, and excessive ripple coefficient of the supply voltage waveform; although the three-phase power supply has solved the problem of single-phase power frequency power supply, t...
