Ultrasonic cyclone, sludge treatment system and working method

The invention provides an ultrasonic cyclone, a sludge treatment system and a working method. The ultrasonic cyclone comprises a cyclone and an ultrasonic vibrator mounted on the cyclone, the ultrasonic vibrator comprises an ultrasonic pipeline generator, an ultrasonic vibration column and an ultrasonic transducer; the ultrasonic pipeline generator is arranged in front of the cyclone, and the ultrasonic transducer is arranged on the ultrasonic pipeline generator; and one end of the ultrasonic vibration column is arranged in the cyclone. The device integrates an ultrasonic function and a cyclone separation function, can realize the functions of separation of superfine sand in sludge, disruption of sludge cells and recovery of energy in the sludge, greatly reduces the process flow of sludge treatment, improves the efficiency of sludge treatment, reduces the investment, land occupation and cost, and is suitable for industrial production. And the sludge treatment method is more energy-saving and more efficient. 本
