Application of ultrasonic vibrating probe in cleaning: Due to the unique design of round tube type, ultrasonic vibrating probe is especially suitable for cleaning all kinds of pipelines. The principle is to convert electric energy into ultrasonic energy and transmit it to scale and water according to its own rules. The inner wall of the pipe makes it get a lot of energy. The shock ultrasonic generated by the ultrasonic during the transmission process causes the scale, water and the inner wall of the pipe to resonate. Due to the different oscillation frequency of the scale, water and the inner wall of the pipe, the water molecules in the pipe collide with each other, generating strong impact force and impact heat transfer surface. The upper scale layer is made to be crispy, peeled off, detached, pulverized, and discharged together with the discharge of the equipment, thereby realizing the cleaning of the inner wall of the pipeline by the ultrasonic vibrating probe. In addition, the ultrasonic vibrating bar can also be used for cleaning the tank body, and can be freely placed at any position of the washing tank. The use is very flexible and convenient, and the occupied volume is small, and the cleaning does not leave a dead angle.
Application of ultrasonic vibrating probe in extraction of traditional Chinese medicine
The ultrasonic component can be used to extract the active ingredients of traditional Chinese medicine. Firstly, an extraction solvent is added to the container, and the Chinese medicinal material is pulverized or cut into granules as needed, and placed in an extraction solvent; the ultrasonic generator is turned on, the ultrasonic vibration probe is mounted on the top of the extraction tank, and ultrasonic are emitted to the extraction solvent, and the ultrasonic is The 'cavitation effect' and mechanical action generated in the extraction solvent can effectively break the cell wall of the medicinal material, so that the active ingredient is in a free state and dissolved in the extraction solvent, and on the other hand, the molecular motion of the extraction solvent can be accelerated, so that the solvent is extracted. It is in rapid contact with the active ingredients in the medicinal materials, and is mutually mixed and mixed.
The excellent temperature of the ultrasonic vibrating probe for extracting the medicine is 40-60 degrees Celsius, so there is no need to equip the 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 heat-labile, easily hydrolyzed or oxidized herbs. The ultrasonic vibrating probe generally runs in about 30 minutes to obtain excellent results. The extraction efficiency is greatly improved compared with the traditional process, and it is not limited by the composition and molecular weight of Chinese herbal medicines. It is suitable for most kinds of Chinese herbal medicines and various ingredients. Extraction (including liquid-liquid extraction and solid-liquid extraction). Therefore, the use of ultrasonic vibrating probes for Chinese medicine extraction has been increasingly adopted by many pharmaceutical companies.
Application of ultrasonic vibrating probe in accelerating chemical reaction
The front end of the ultrasonic vibrating probe horn is closely attached to the outer wall of the kettle or into the cavity of the kettle body. The ultrasonic transducer can send ultrasonic to the chemical reactants in the cavity, and the liquid to be treated is ultrasonic. The cavitation effect can cause changes in the activity of the reaction system, destroy the solvent structure of the chemical reactants in the cavity, generate instantaneous high temperature and high pressure sufficient to initiate the chemical reaction, form a local high energy center, and promote the smooth progress of the chemical reaction. The main factor of the catalytic reaction of the vibrating probe.
The secondary effects of ultrasonic such as mechanical shock, emulsification, diffusion, crushing, etc. are all beneficial to the full mixing of the reactants. The ultrasonic vibrating probes use high-power concentrating transducers, which can make the material undergo intense forced motion and accelerate. The transfer of matter can replace traditional mechanical agitation. Of course, in practical applications, it is better to use the electric mixer to accelerate the reaction.
Application of ultrasonic vibrating probe in anti-scaling
We take the heat exchanger as an example. The ultrasonic vibrating probe is generally installed in the inlet of the heat exchanger. It is controlled by flange connection and control valve. It can be used to repair and maintain the ultrasonic equipment without stopping production. The main principle is that the ultrasonic transmits and generates energy during the transmission process, and the material molecules such as scale, water and metal heat exchange surface obtain energy in the vibration process, and the water in the heat exchange tube generates vibration and intense collision while acquiring energy. The water molecules containing various inorganic salts which are unstable in themselves generate numerous cavitation bubbles (cavitation), forming a water molecule cavitation cavity. These bubbles, when rapidly expanding and suddenly closing, produce local impacts of thousands of atmospheres and high-speed jets of up to 400 km/h and high energies of more than 5000 k. These energies destroy the combination of positive and negative ions with acid radicals and destroy the formation of scale. Conditions to achieve anti-scaling.
Application of ultrasonic vibrating probe in water treatment
The ultrasonic vibrating probe gathers the ultrasonic probe to concentrate the energy, and the strong sound intensity can be obtained on the end face of the ultrasonic radiation. Due to the energy gathering effect of the horn, the sound energy density is greatly improved; the reaction can be accurately designed according to the density of the acoustic energy. The emitting end face of the probe is generally designed to be detachable, so that the probe of the appropriate size of the end face can be selected at any time according to the required sound intensity. At the same time, when the probe is severely corroded by cavitation, only the end portion needs to be replaced without having to replace the price. Expensive whole vibration probe. Ultrasonic vibrating probes can be used to treat various refractory organic wastewaters. They have been used in monocyclic aromatic compounds, polycyclic aromatic hydrocarbons, phenols, chlorinated hydrocarbons, chlorinated hydrocarbons, organic acids, dyes, alcohols, ketones, etc. Research on wastewater treatment and 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, landfill leachate, etc., and achieved good results.
