The invention relates to a hydraulic ultrasonic scale removal device for a wet electric precipitation demister and a scale removal process. At present, a hydraulic ultrasonic scale removal device for the wet electric precipitation demister for realizing synchronous scale removal and prevention and a scale removal process are absent. The scale removal device is characterized by comprising a wet electric precipitation demister, an ultrasonic transmitting system, an ultrasonic detector, a hydraulic scale removal device and a control system, wherein the ultrasonic transmitting system comprises an ultrasonic transmitter, an ultrasonic generator and attached facilities; the ultrasonic transmitter, the ultrasonic detector and the hydraulic scale removal device are arranged in the wet electric precipitation demister; and the control system is connected with the attached facilities. The scale removal process comprises the following steps: allowing flue gas to pass through the wet electric precipitation demister, starting the ultrasonic generator, and crushing, dispersing and loosening the smoke dust on an anode plate and cathode rays; and starting the hydraulic scale removal device, and performing hydraulic scouring and scale removal on the cathode rays and anode plate. According to the device disclosed by the invention, the design is reasonable, and synchronous scale removal and prevention can be realized.
Description
technical field [0001] The present invention relates to a hydraulic ultrasonic descaling device and a descaling process, in particular to a hydraulic ultrasonic descaling device and a descaling process for a wet electrostatic precipitator demister, which is specially used in a wet electrostatic precipitator demister, such as The utility model is applied in a wet electrostatic precipitator or a mist eliminator, and belongs to the technical field of air pollution control. Background technique [0002] With the increasingly stringent national environmental protection policies, domestic thermal power units in service and newly-built thermal power units are equipped or plan to be equipped with wet electrostatic precipitators (fog) to ensure that boiler smoke and dust discharge meets the standards. At present, the mist eliminators or wet electrostatic precipitators installed in active thermal power units at home and abroad have a certain degree of fouling problem. The existing onl...
