Abstract

The invention discloses a method for carrying out detection and control on ultrasonic intensity in water treatment. The method is characterized in that the output of a power amplifier in water treatment is monitored by using a system for carrying out detection and control on ultrasonic intensity in water treatment, if a detected acoustic intensity is deviated from a reference acoustic intensity, the system automatically adjusts the output power of the power amplifier, so that the value of the acoustic intensity of an ultrasonic water treatment system always remains at a preset reference value, thereby providing an automatic acoustic-intensity stabilization system for researches on ultrasonic water treatment, and ensuring the service life of an ultrasonic transducer; meanwhile, through carrying out measurement of acoustic intensity parameters, an effect that the ultrasonic transducer with different operating frequencies can carry out water treatment under the condition of a same acoustic intensity parameter, therefore, the method disclosed by the invention can be used for solving the problem that in the existing water treatment technology, factors affecting the operation of degradation can not be researched because of the lack of important parameters.

Description

technical field [0001] The invention relates to a method for detecting and controlling ultrasonic sound intensity in water treatment, and belongs to the technical field of ultrasonic detection and control. Background technique [0002] In recent years, ultrasonics has been the most widely used part in the development of acoustics, and power ultrasonic technology is one of the most important branches of ultrasonics. Its working principle is to change or accelerate some physical, Chemical and biological properties or states. In power ultrasound technology, sound intensity is a very important physical quantity. The measurement of its value has a very important impact on the development of ultrasonic transducers and the application of power ultrasound, such as ultrasonic cleaning, ultrasonic medical treatment and ultrasonic water treatment. At present, the measurement methods of ultrasonic sound intensity in liquid mainly include: thermal probe method, radiation force method, s...
