Control method of high-voltage electrostatic dedusting energy-saving device

Abstract

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.
