A MATERIAL DRYING AND PYROLYZING METHOD

摘要

This invention discloses a material drying and pyrolyzing method, including the following steps: sending the material into rotary kettle; making use of the microwave energy to heat the materials within the rotary kettle to pyrolyze and decompose the material in order to get decomposed gas and solid substance; condensing and recycling the gas generated from the decomposing; recycling and disposing the solid substance generated from the pyrolyzing. The method of this invention makes use of the microwave energy to rapidly heat the material inside the rotary kettle, and rotates the rotary kettle at the same time to make the material more uniformly heated, improve the material pyrolyzing efficiency, which can greatly improve the pyrolyzing and separating efficiency of the material and effectively reduce the energy consumption, with the improvement of the safety performance of the equipment operation. In the meanwhile, it also avoids the secondary pollution to the environment caused by the burning of the heating energy, thus effectively improves the economic and social benefits.
