In particular, when in use,

microwaves are electromagnetic waves, as are radio waves, television signals, communication radars, infrared rays, visible light, and the like, but have different wavelengths. Microwaves are electromagnetic waves (wavelength 1m to 1 mm) having a frequency of 300MHz to 300KMHz, and are generally used in television, broadcasting, and communication technologies. In recent times, microwave is used as an energy source, a branch technology is expanded, and heating, drying and sterilization are carried out in industry and agriculture; carrying out chemical reactions such as catalysis and extraction and exciting plasmas in the chemical industry;

the material medium is composed of polar molecules and nonpolar molecules, and under the action of an electromagnetic field, the polar molecules are changed from a random distribution state to be oriented and arranged along the direction of the electric field. Under the action of microwave electromagnetic field, these orientation motions are continuously changed at frequencies of billions of times per second, so that the violent motion and collision friction of molecules are caused, and heat is generated, so that electric energy is directly converted into heat energy in the medium. It can be seen that microwave heating is heating of dielectric material itself by loss of electric field energy. The dielectric constant epsilonr and the dielectric loss tangent tg delta of different dielectric materials are different, so that the thermal effect under the action of the microwave electromagnetic field is different. Substances organized by polar molecules can better absorb microwave energy. The water molecules are extremely strong in polarity and are the best medium for absorbing the microwaves, so that materials containing the water molecules must absorb the microwaves. Another class consists of non-polar molecules that are substantially non-absorbing or minimally absorbing to microwaves, such as polytetrafluoroethylene, polypropylene, and glass, ceramic, etc., that are transparent to microwaves and non-absorbing to microwaves, and that can be used as containers or supports for microwave heating or as sealing materials.

The microwave is obtained by passing direct current or 50Hz alternating current through an electric vacuum device or a semiconductor device and making electrons move specially in a magnetic field. This movement can be explained simply as follows: from the viewpoint of electrical structure, one kind of molecules is called as non-polar molecular dielectric, and the other kind is called as polar molecular dielectric. In general, they are randomly arranged, and if they are placed in an alternating electric field, the polar molecular orientation of these media also changes with the change in polarity of the electric field, which is called polarization. The stronger the applied electric field, the stronger the polarization, the faster the applied electric field changes polarity, the faster the polarization, and the more intense the thermal motion of the molecules and the friction between adjacent molecules. In the process, the conversion of electromagnetic energy into heat energy is completed, when the heated material is placed in a microwave field, polar molecules of the heated material are oscillated and rubbed back and forth at high frequency of billions times per second along with the microwave frequency, and the generated heat is enough to ensure that the material is heated and dried in a short time. In a microwave oven, a magnetron is used to convert electrical energy into microwave energy.

Compared with the traditional heat conduction heating mode, the microwave heating mode has great advantages, and the main advantages are as follows:

(1) The heating speed is high

Conventional heating (such as flame, hot air, electric heat, steam, etc.) is to transfer heat to the surface of an object to be heated first by heat conduction, convection, and heat radiation, and then to raise the central temperature step by heat conduction (also commonly referred to as external heating). It takes a certain heat conduction time to reach the desired temperature in the central part, whereas it takes longer for objects with poor heat conduction. Microwave heating belongs to an internal heating mode, electromagnetic energy directly acts on medium molecules to be converted into heat, the medium is heated inside and outside simultaneously through transmission, heat conduction is not needed, and therefore uniform heating can be achieved in a short time.

(2) Uniform heating

When the heating is carried out by an external heating mode, in order to increase the heating speed, the external temperature needs to be increased, and the temperature difference gradient is increased. However, this is accompanied by the generation of exogenous or endogenous phenomena. When the microwave is heated, the microwave can uniformly permeate regardless of the shape, and heat is generated, so that the uniformity is greatly improved.

(3) Energy-saving high-efficiency

Different materials have different absorptivity to microwaves, and substances containing moisture easily absorb microwave energy. Glass, ceramic, polypropylene, polyethylene, fluoroplastic, etc. rarely absorb microwaves, metals reflect waves, and none of these materials can be heated by microwaves. In microwave heating, the heated material is generally placed in a heating chamber made of metal, the heating chamber is a closed cavity body for electromagnetic waves, the electromagnetic waves cannot be leaked out and only can be absorbed by a heated object, and air in the heating chamber and a corresponding container cannot be heated, so that the heat efficiency is high. Meanwhile, the environmental temperature of the workplace is not increased, and the production environment is obviously improved.

(4) The heat pipe is ready to use when opened and has no thermal inertia.

(5) Clean and sanitary

When food, medicine and the like are processed and dried, the microwave heat effect and the biological effect can be quickly killed and killed at a lower temperature, and the nutrient components and the original color and luster can be maintained to the maximum extent, so that the microwave heating is widely applied to the food industry.

(6) Selective heating

Materials with different properties have different absorption losses to microwaves, so that the microwave drying device has the characteristic of selective heating and is beneficial to the drying process. Since the absorption loss of water molecules to microwaves is the greatest, the microwave absorption power is higher at the sites with high water content than at the sites with lower water content, and the drying rate tends to be uniform. However, some substances have negative temperature coefficients, and the higher the temperature is, the larger the epsilonr and the better the tg delta is, so that the positive feedback causes the temperature of the part to rise sharply. The microwave heating of such materials requires careful design of the manufacturing process.

(7) Safe and harmless

Microwave energy is typically transmitted within a closed heating chamber, waveguide, made of metal. The company integrates years of processing experience and technical equipment, adopts advanced design, and strictly controls the microwave leakage at the feed/discharge port, the observation window, the furnace door and the like within the national safety standard index, which is greatly lower than the safety standard established by the country. And the microwave does not belong to radioactive rays and has no harmful gas emission, thereby being a very safe heating technology. Meanwhile, the company adopts advanced electromagnetic compatibility (EMC) technology, and can further control the influence on the power utilization environment and the space in the aspects of conduction and radiation of a microwave system.

Based on the above microwave characteristics, in the microwave waste pyrolysis device, under the direct action of microwave energy, microscopically, the molecules of the waste are randomly arranged, the waste is placed in an alternating electric field, the polar molecule orientation of the media also changes along with the polarity change of the electric field, the stronger the external electric field is, the stronger the polarization effect is, the faster the polarity change of the external electric field is, the faster the polarization is, and the more violent the thermal motion of the molecules and the friction effect between adjacent molecules are. The method has the advantages that a large amount of heat energy is generated, bonds between macromolecules are cut off, oxygen is not involved in the whole pyrolysis process, micromolecular solid, liquid and gas are generated, the gas can be discharged after the gas is purified, the solid and the liquid can be compressed in a concentrated mode, and the final product can achieve the effects of volume reduction and weight reduction.
