Description
Technical field
The utility model is about a kind of microwave heating equipment, refers to especially the reaction unit that utilizes microwave heating of the continued operation of a kind of energy and high temperature high voltage resistant.
Background technology
Microwave has the short (high (obvious characteristic such as 300MHz～300GHz), Quantum Properties of 1m～1mm), frequency of wavelength.The basic principle of microwave heating is conduction and the dielectric polarization of charged particle.Ionic conduction refers to that the ion in medium produces transference cell and produces heat at elect magnetic field.Dielectric polarization mechanism refers under electromagnetic field effect, and polar molecule is from the polarity oriented of random distribution state shift according to electromagnetic field.Under the effect of microwave high-frequency electromagnetic field, these orientation movements agree to the frequency of alternating electromagnetism constantly to change, and cause strenuous exercise and the collision friction of molecule, thereby produce heat, cause electric field energy to be converted into the interior heat energy of medium.Nonpolar molecule is because internal charge is evenly distributed not by microwave heating.Microwave heating has the characteristics of penetrability, instantaneity and selectivity heating, and thermal loss is little, easy to operate, sanitation and hygiene are pollution-free, is used widely in life is produced.
Traditional microwave heating technique is mainly for heated food, and is in recent years, along with the development of microwave heating technique, that the report that microwave heating technique is applied on chemical engineering industry is increasing.
