Ultrasonic cleaning machine: the preset application of ultrasonic cavitation in chemical industry

Ultrasonic cleaning machine: Ultrasonic cavitation In the chemical industry, the ultrasonic cleaning machine is used. Ultrasonic vibration usually refers to high frequency sound waves with vibration of 20,000 times/s or more. At present, ultrasonic is commonly used in cleaning, cutting, drilling, medical diagnosis, geological measurement, metal non-destructive testing and so on. In the chemical industry, the use of ultrasound has also been increasingly confronted, resulting in a new interspersed discipline -- sonic chemistry.

As early as the 1920s, Richard and Loomis of the United States first studied the effects of ultrasound on various solids, liquids, and solutions, and found that ultrasonic waves can accelerate chemical reactions. Because of the low level of ultrasound skills at the time, research and application have been greatly affected and limited. In the mid-1980s, following the development and development of ultrasonic equipment, it provided the primary premise for the application of ultrasonic in the chemical and chemical process, and it also enabled the research task of this category to be quietly quiet for nearly half a century. The first meeting of ultrasound chemistry was held in the UK in April 1986. Later, countries such as Europe and the United States successively held repeated sonochemical research conferences, discussed the mechanism and application of sonochemistry, and announced a number of valuable academic papers and monographs. At present, how to apply the results of sonochemical research to industrial production as soon as possible has become a hot spot in the world. In particular, the United States, Britain, France, Japan, Russia and other countries have achieved some pauses in industrialization. China's research tasks in this area started late, and a large number of research reports were concentrated in the 1990s. Among them, Yunnan University, Tsinghua University, Nanjing University, and South China University of Technology have done a lot of tasks in ultrasound practice and application. The power of sonochemical use is mainly due to ultrasonic cavitation. Ultrasonic cavitation is an extremely complex physical scene. It is a very important basic research topic in the application of ultrasonic technology. In recent years, people have been interested in it and their enthusiasm is very strong. The cavitation effect of ultrasonic cleaning machine is also common. Used in food, medical, petroleum, light industry and other industries.
