Study on scale inhibitive mechanism and its application of power ultrasonic in heater transfer equipment

Scale deposition is a hot issue and difficult problem for researchers. When scale grows, theutilization of heat power becomes lower and the operations are going to be abnormal, which increasesthe production cost. In our study, a scale inhibitive mechanism was revealed and the ultrasonicparameters were optimized. In addition, a novel type of ultrasonic equipment was devised. The factory-scale experiment results showed that the ultrasonic technique could prevent scale from appearance,increase the evaporation rate of evaporation system remarkably, decrease clearing times of the heattransfer equipment and consumption of chemical cleaning agent and prolong the life expectance ofequipment without chemical pollution.
