Operation optimization method and device for electrostatic composite dust collector

The invention discloses an operation optimization method and device for an electrostatic composite dust collector. The operation optimization method comprises the following steps: implementing an operation adjustment experiment to the electrostatic composite dust collector, utilizing ash removal interval time and operation resistance obtained by meeting preset conditions during the experiment process to draw a first relation fitting straight line, further obtaining real-time control constant parameters and offset of the ash removal interval time, utilizing a high voltage output value in an electric field and a boiler load value obtained by meeting the preset conditions during the experiment process to draw a second relation fitting straight line, further obtaining real-time control constant parameters and offset of the high voltage output value in the electric field, furthermore utilizing the first relation fitting straight line and the real-time changed operation resistance variation value to obtain a control value of the corresponding ash removal interval time, and utilizing the second relation fitting straight line and the real-time changed boiler load value to obtain a control value of the corresponding high voltage output value in the electric field.
