Problems solved by technology

[0002] After long-term production, sales and after-sales service, it is found that there are some problems in the existing ultrasonic anti-scaling and descaling devices, some are design problems, some are improper selection of components, the biggest problem is the anti-scaling and descaling The descaling effect is not ideal. With the continuous accumulation of problems and the in-depth understanding of the ultrasonic descaling mechanism and magnetic transducer, a new design concept has been proposed, and a step-by-step power ultrasonic strong pulse anti-scaling and descaling device and step-by-step control method
[0003] In the design of the step-by-step power ultrasonic strong pulse anti-scaling and descaling device, the power device on the transducer is a high-frequency thyristor, but there are two performance parameters that do not meet the control requirements, one is the maximum withstand voltage of 1200V The other is that the cut-off frequency is up to 15KHz, which is too far away from the ultrasonic frequency. The only way to solve the frequency problem is to wind two sets of coils on the transducer and control them separately, so that the operating frequency of the thyristor can be reduced by half. , the problem is solved
There is another problem. Once the thyristor is turned on under DC, it will be out of control. Only when the main circuit current is less than the maintenance current can it be turned off. The discharge process makes the thyristor realize the ideal turn-off process

Abstract

The invention provides a stepping type power ultrasonic strong pulse scale preventing and removing device and a control method. The control mode that a main triggering loop corresponds to a set of transducer coils is adopted by the device, so that the ultrasonic pulse vibrating effect is higher; and meanwhile, two silicon controlled main loops with the different connecting modes are triggered alternately so that two sets of coils of a transducer can work alternately; and the stepping type control mode is adopted for scale preventing and removing equipment, continuous ultrasonic waves are obtained, a dynamic film formed by ultrasonic waves on the equipment pipe or plate wall is prevented from being damaged by pause of the ultrasonic waves, scale prevention and removal are greatly facilitated, and the effect is obvious, especially for equipment with the high scaling speed.
