A kind of internal and external circulation type ultrasonic-microwave stirred autoclave
Technical field:
The present invention relates to ultrasonic-microwave-microwave technique application apparatus field, it is specifically related to internal and external circulation type ultrasonic-microwave-microwave stirred autoclave.
Background technology:
Ultrasonic-microwave and microwave have important effect in chemosynthesis, and its chemical effect can be accelerated chemical reaction velocity and specific reaction is had selectivity. When ultrasonic-microwave is propagated in media as well, due to the interaction of ultrasonic-microwave and medium, make the change with chemistry of medium generation physics, thus produce a series of mechanics, calorifics, the effect of ultrasound with chemistry of electromagnetism. The mechanical effect of ultrasonic-microwave can facilitate the dispersion of the emulsification of liquid, the liquefaction of gel and solid; The small bubbles that ultrasonic cavitation is formed can constantly move with the vibration of surrounding medium, grow up or vanish suddenly. When vanishing, surrounding liquid pours bubble suddenly and produces high temperature, high pressure, produces shock wave simultaneously; The effect of ultrasonic-microwave can impel and occurs or accelerate some chemical reaction. Such as pure distilled water produces hydrogen peroxide after supersound process; The water being dissolved with nitrogen produces nitrous acid after supersound process; The aqueous solution of dyestuff is understood variable color after supersound process or is faded. Ultrasonic-microwave also can accelerate hydrolysis, the decomposition and aggregation process of many chemical substances. Photochemistry and electrochemical process are also had a significant effect by ultrasonic-microwave. The aqueous solution of each seed amino acid and other organic substances is after supersound process, and characteristic absorbance spectrum band disappears and generally absorbs in uniform, and this shows that cavatition makes molecular structure there occurs change. Under the effect of microwave high-frequency electric field, polar molecule repeatedly fast orientation rotate and frictional heat; In body, ion vibrates under microwave action and also vibration energy can be converted into heat; General molecule makes thermal motion energy increase after also absorbing microwave energy; Reactant molecule will produce distortion and vibration, and then affects the generation etc. of chemical reaction.
Owing to thermo-responsive degree of some reactions are different, in other reaction process then can endothermic heat of reaction or exothermic heat of reaction, just unavoidably there is heat transfer process in this. Can not dispelling the heat in time or reaction heat cannot regulate and causes temperature control in system if stirred, chemical reaction process and equipment all can produce serious danger. The microwave that common band stirs or ultrasonic-microwave device, for the control of device internal heat, all are had no idea to realize, application are had certain restriction.
