Description

technical field [0001] The invention relates to a material continuous pyrolysis gasification device. Background technique [0002] Traditional heating methods use radiation, convection, and conduction to heat from the surface to the inside. In order to avoid excessive temperature gradients, the heating speed is often not too fast, and the components of the material cannot be selectively heated. Because microwaves can directly penetrate into the material, compared with traditional heating methods, microwave heating can achieve balanced heating inside and outside the material, which has the advantages of fast heating rate and high energy utilization efficiency, and microwave can treat components with different dielectric properties in the material. Selective heating is performed. Therefore, the particularity of microwave heating makes pyrolysis products have greater advantages compared with traditional gasification technology, and it is a promising material heating method. ...

Problems solved by technology

However, the arrangement of the microwave source in this method is limited to the lower part of the reaction chamber, and the space is limited. To realize flash pyrolysis cracking, it is necessary to equip a high-power magnetron to increase the microwave field strength, which will greatly increase the cost.
