Ultrasonic sonochemistry 1. Overview of Guosheng ultrasonic sonochemical equipment: As a physical tool and tool, ultrasonic chemical processing technology can produce a series of conditions close to extremes in the medium of chemical reaction, which can not only stimulate or promote many Chemical reactions, speeding up chemical reactions, and even changing the direction of certain chemical reactions, produce some unexpected effects and miracles, which is ultrasonic chemistry. Ultrasonic chemistry can be applied to almost all chemical reactions such as extraction and separation, synthesis and degradation, biodiesel production, microbial treatment, degradation of toxic organic pollutants, organisms
As a physical means and tool, ultrasonic chemical treatment technology can produce a series of near-extreme conditions in the medium of chemical reaction. This energy can not only stimulate many chemical reactions, accelerate the speed of chemical reaction, but also change the direction of some chemical reactions, which is called ultrasonic chemistry. Ultrasound chemistry can be applied to many chemical reactions, such as extraction and separation, synthesis and degradation, biodiesel production, microbial control, degradation of toxic organic pollutants, biodegradation treatment, cell comminution, dispersion and coagulation, etc. Ultrasound chemical treatment equipment also has a prominent advantage, that is, it has no moving parts, no electromagnetic radiation, simple installation and fixing, suitable for high pressure, high temperature, toxic, explosive dangerous environment applications. Another application of ultrasonic sonochemical treatment equipment is in the field of sewage treatment and scale prevention and removal. Many experts and scholars have done a lot of research and experiments to prove that ultrasound is effective in scale prevention and removal of pipelines and equipment.
The working principle of ultrasonic acoustical equipment:
At present, the research of ultrasound chemistry has involved many fields, such as chemistry, materials science, environmental protection, including the application in organic synthesis and treatment of toxic organic pollutants which are difficult to biodegrade. Ultrasound has the characteristics of strong propagation direction, high vibration intensity of medium and cavitation in liquid. Ultrasound can promote chemical reactions that cannot occur under conventional conditions or improve the existing reaction speed and degree. However, these phenomena are not the result of the direct action of acoustic waves on the reactants. It is generally believed that the above phenomena are mainly caused by the mechanical and cavitation effects of ultrasound, which are the result of the changes in the reaction conditions and environment. Mechanical action - introducing ultrasonic wave into chemical reaction system, ultrasonic wave can make substance move violently, produce one-way force to accelerate the transfer and diffusion of substance, can replace mechanical stirring, can make substance peel off from the surface, so as to renew the interface. Cavitation - In some cases, the generation of ultrasonic effect is related to the mechanism of cavitation. Acoustic cavitation refers to a series of dynamic processes of small bubbles (holes) existing in liquid under the action of acoustic wave: oscillation, expansion, contraction and even collapse. These two effects are the main reasons for the acceleration and activation of chemical reactions by ultrasound. Our company produces focused probe type high-power ultrasonic acoustic chemical treatment equipment. Without changing the existing production equipment and process flow of customers, you can upgrade your ordinary equipment to chemical equipment with ultrasonic through simple installation. The ultrasonic power is large, the investment is small, the installation is simple, the power consumption is low, the adaptability is wide and the installation is simple.
Ultrasound chemical treatment equipment consists of three parts: ultrasonic transducer, special driving power supply and reactor. Ultrasound transducer components mainly include high-power ultrasonic transducer, horn and tool head, which are used to generate ultrasonic mechanical vibration and transmit the vibration energy to liquid. The transducer converts the input electric energy into mechanical energy, i.e. ultrasound. The tool head is connected with the horn. The horn transmits the ultrasonic energy vibration to the tool head, and then transmits the ultrasonic energy to the chemical reaction liquid by the tool head.
