The electric dust collector refers to a device that collects dust that has been negatively charged or positively charged by causing the dust collecting electrode to become an anode and the discharge electrode to become a cathode. Generally, a high voltage is applied between the dust collecting electrode and the discharging electrode to generate an unequilibrium electric field by a corona discharge so that the charged dust or gas is collected by the electrostatic force on the dust collecting electrode. Electrostatic precipitators can be applied to large workplaces where dust or gas is generated due to high discharge electrodes, as well as to workplaces where dust or fine particles act. A high voltage of, for example, 30 to 100 kV is required for the dust or particulate matter in the dust collecting device, and may be divided into a DC voltage method or a micro pulse method according to the voltage application method. Such an electrostatic precipitator needs to be cleaned or cleaned at regular intervals. Various techniques for cleaning the electrostatic precipitator related thereto are known.

[

The automatic washing control system according to the present invention can be applied to the automatic washing of the electric dust collector 10 composed of a plurality of dust collecting filters. The plurality of dust collecting filters may be connected to each other in parallel or in series to form one dust collecting device. And each of the dust collecting filters can be electrically connected and can operate independently or operate together.

The pressure measurement by the detection sensor 15 means to measure the pressure of the air stream flowing into the electrostatic precipitator 10 and the pressure of the air strip discharged from the electrostatic precipitator 10. The detection sensor 15 can measure the amount of discharged air. For example, when the amount of air to be charged is high, it means that the dust collecting performance of the electric dust collector 10 is weakened. Such a detection sensor 15 can confirm the dust collecting performance of the electric dust collector 10 by measuring factors related to the dust collecting performance of the electric dust collector 10. And the information detected by the detection sensor 15 may be transmitted to the control unit 11. [
