Application of ultrasonic vibrating rod in cleaning

Due to the unique round tube design characteristics, the ultrasonic vibrating rod is particularly suitable for cleaning various pipes. The principle is to convert electric energy into ultrasonic energy, and transfer it to scale, water and the inner wall of the pipe according to its own laws, so that it can obtain great energy. The shock wave generated in the transmission process of the ultrasonic wave causes the scale, water and the inner wall of the pipeline to resonate. Due to the different vibration frequencies of the scale, water and the inner wall of the pipeline, the water molecules in the pipeline collide violently, generating a strong impact force, impacting the scale layer on the heat exchange surface, making it brittle, peeling, falling off and smashing, and discharging it together with the sewage of the equipment, thus realizing the thorough cleaning of the inner wall of the pipeline by the ultrasonic vibrating rod. In addition, the ultrasonic vibrating rod can also be used for cleaning the tank body. It can be freely placed at any position of the cleaning tank. It is very flexible and convenient to use. It occupies a small space and does not leave a dead angle for cleaning.

Application of ultrasonic vibrating rod in extraction of traditional Chinese Medicine

The effective components of traditional Chinese medicine can be extracted by ultrasonic vibrating rod. First, add the extraction solvent into the container, crush or cut the Chinese herbal medicine into granules as required, and put it into the extraction solvent; Start the ultrasonic generator, install the ultrasonic vibrating rod on the top of the extraction tank, and send ultrasonic waves to the extraction solvent. On the one hand, the "cavitation effect" and mechanical action generated by the ultrasonic wave in the extraction solvent can effectively break the cell wall of the medicinal materials, make the effective components in free state and dissolve into the extraction solvent, on the other hand, it can accelerate the molecular movement of the extraction solvent, so that the extraction solvent and the effective components in the medicinal materials can quickly contact each other, Dissolve and mix with each other.

The optimal temperature for ultrasonic vibrating rod extraction of medicinal materials is 40-60 ℃, so it is not necessary to equip a boiler to provide steam heating, which is conducive to saving energy and improving environmental pollution. More importantly, it has a protective effect on the active ingredients in the medicinal materials that are unstable in heat, easy to hydrolyze or oxidize. The ultrasonic vibrating rod can generally run for about 30 minutes to obtain the best effect. The extraction efficiency is greatly improved compared with the traditional process, and is not limited by the nature and molecular weight of the components of Chinese herbal medicines. It is suitable for the extraction of most kinds of Chinese herbal medicines and various components (including liquid-liquid extraction and solid-liquid extraction). Therefore, more and more pharmaceutical companies have adopted ultrasonic vibrating rod to extract traditional Chinese medicine.

Application of ultrasonic vibrating rod in accelerating chemical reaction

The front end of the head of the ultrasonic vibrating rod tool is close to the outer wall of the kettle body or extends into the kettle cavity of the kettle body. The ultrasonic transducer can send ultrasonic waves to the chemical reactants in the kettle cavity. The treated liquid can cause changes in the activity of the reaction system due to the "cavitation" effect of ultrasonic waves, destroy the solvent structure of the chemical reactants in the kettle cavity, generate instantaneous high temperature and high pressure sufficient to trigger chemical reactions, and form a local high-energy center, To promote the smooth progress of the chemical reaction, which is the main factor for the catalytic chemical reaction using the ultrasonic vibrating rod.

The secondary effects of ultrasonic wave, such as mechanical vibration, emulsification, diffusion and crushing, are conducive to the full mixing of reactants in all directions. The ultrasonic vibrating rod adopts a high-power concentrated energy transducer, which can make the material move violently, accelerate the transmission and diffusion of the material, and replace the traditional mechanical stirring. Of course, in practical application, it is better to accelerate the reaction when used with an electric stirrer.

Ultrasonic vibrating rod can be used to treat all kinds of organic wastewater which is difficult to degrade. At present, it has been used to treat wastewater containing monocyclic aromatic compounds, polycyclic aromatic hydrocarbons, phenols, chlorinated hydrocarbons, chlorinated hydrocarbons, organic acids, dyes, alcohols, ketones, etc., and has achieved good results. In the actual industrial wastewater, the equipment has been used to treat papermaking wastewater, printing and dyeing wastewater, tannery wastewater, coking wastewater, pharmaceutical wastewater, garbage leachate, etc., and achieved good results.

In addition, in some scenic lakes and rivers, the ultrasonic vibrating rod can also be used to kill and suppress algae. The mechanical effect, cavitation effect, thermal effect and acoustic flow effect of ultrasonic wave make the algal cell break and the chemical bond break in the material molecule act on the outer wall of the alga and make it break and die, so as to achieve the effects of lifting and breaking of the algal vacuole, cell death or growth inhibition, causing a series of biological effects. The cavitation effect causes the microbubbles in the liquid to expand rapidly and then close suddenly, Shock wave and jet are generated to eliminate algae and balance water environment ecology. Low intensity ultrasound destroys the structure and function of phycobilisome and interferes with the synthesis of chlorophyll, thus achieving the purpose of inhibiting the growth of algae.
