Document Type and Number:
WIPO Patent Application WO/2016/023488
Kind Code:
A1
Abstract:
A control method and system for passive cleaning of an electrostatic precipitator of a smog-removing fresh air system. The method comprises the following steps: S100: detecting outdoor humidity, φ; S200: with φ1 being a maximum humidity setpoint, if φ ≤ φ1, then proceeding to step S300, and if φ > φ1, then proceeding to step S201; S300: starting automatic cleaning of an electrostatic precipitator (7); S400: when cleaning is completed, transmitting power to a plate of the electrostatic precipitator (7); S500: if the electrostatic precipitator (7) can be turned on, then proceeding to step S600, if the electrostatic precipitator (7) cannot be turned on, then proceeding to step S501; and, S600: the electrostatic precipitator (7) starting steps of normal operation. The method allows automatic determination of a plate short circuit and performance of a control operation corresponding thereto, thus facilitating use of the smog-removing fresh air system. The system comprises a humidity sensor (9) and a control device (10). The humidity sensor (9) is arranged outdoors and is connected to the control device (10). The control device (10) is connected respectively to a three-way solenoid switching valve (11) and a control valve set of the electrostatic precipitator (7). The system can reliably and effectively implement the control method.
