A kind of microwave oven device and its pyrolysis method for pyrolysis

Abstract

The invention discloses a microwave oven device for pyrolysis and a pyrolysis method thereof, which comprises a microwave furnace body and a reaction chamber arranged outside the furnace body; a closed end cover is arranged on the top of the reaction chamber body, and the There are four side air inlets distributed on the surrounding wall, four bottom air inlets are arranged at the bottom of the reaction chamber, and an electric heating device is arranged on the peripheral wall of the reaction chamber; the reaction chamber is connected with the furnace body through a movable link bracket. According to the needs of the material to be pyrolyzed, select the number of side air inlets or bottom air inlets, turn on the stop button and start button, after completing the above operations on the body, set the upper and lower limits of temperature, power level, and set the reaction according to needs After setting the time, turn on the electric heating button to keep the reaction chamber warm. When the actual temperature measured by the thermocouple reaches 300 degrees, turn on the microwave button, and choose whether to turn on the stirring function according to the experimental needs; when the pyrolysis of the material is completed, the microwave oven will automatically turn off.

Description

technical field [0001] The invention relates to the field of microwave machinery, in particular to a microwave oven device for pyrolysis and a pyrolysis method thereof. Background technique [0002] Microwave is an electromagnetic wave with a frequency of 300MHz-300GHz. Microwave heating is the conversion of microwave energy absorbed by the material in the electromagnetic field into heat energy of the material, which belongs to volumetric heating. Microscopically, when microwaves act on matter, dipoles will form in the dielectric material, and the existing dipoles will rearrange and vibrate at a speed of hundreds of millions of times per second with the high-frequency alternating electromagnetic field. Molecules need to be rearranged along with the direction of the changing high-frequency electromagnetic field, and the molecules have a certain thermal motion and there is mutual interference between the molecules, resulting in friction. In this microscopic process, the micro...
