The invention discloses a control method of a high-
voltage electrostatic dedusting energy-saving device. The control method which is applied to a high-
voltage electrostatic dedusting energy-saving controller comprises the following steps: 1, a control
chip outputs an
electric heating signal to a plurality of electric heater driving circuits in advance; 2, the control
chip acquires temperature signals of the electric heaters through a plurality of electric heater heat sensors; 3, the control
chip compares anyone of the temperature signals with a preset value; 4, whether the compared temperature
signal reaches the preset value is judged, step 2 is repeatedly carried out if not, and step 5 is carried out if so; 5, constant
temperature control programs are started; 6, whether all the electric heaters enter the constant
temperature control programs is judged, the step 2 is repeatedly carried out if not, and step 7 is carried out if so; and 7, the step up
transformer drive circuit, the
rapping motor drive circuit, the sensors and the
multipath communication interface control programs of the controller are started. The control method has the beneficial effects of electric heater
life prolongation, maintenance cost reduction and energy saving.
