Abstract

This invention relates to a heating device, specially to a resonant cavity structure heated by a microwave resonant cavity which provides a new design of a microwave resonant cavity heated at the same time by the inside and surface including a resonant cavity, a cut-off wave guide and a coupling wave guide, among which, the cavity is a vertical hollow cylinder, the magnet control tube generates microwave to enter into the resonant cavity via the waveguide, materials are heated in the cavity and chemical reactions are taken in the cavity. The system is mounted with a microwave leakage -detecting sensor to test the leakage on-line timely and realizes the real-time on-line display.

Description

Technical field [0001] The invention relates to a heating device, in particular to a structure of a resonant cavity heated by a microwave resonant cavity, which is mainly applied to chemical reactions and belongs to the technical field of microwave chemistry. Background technique [0002] The traditional heating method requires a high-temperature heat source, such as flame, hot air, electric heating, etc. The surface heating source is used to heat the surface of the object first, and then conduction and convection transfer the heat from the outside to the inside of the heated object. , Gradually increase the center temperature of the object. It takes a certain amount of time for the center to reach the required temperature, so the heating speed is very slow; if it is an object with poor thermal conductivity, the time required is longer. This is a relatively slow and long process, with low efficiency, long operation time, and no selectivity in the heating process. However, the use...
