文中提出一种与物料种类无关的热解过程分类新方法。首先,根据热量传输路径,物料受热过程分为壁面加热物料、壁面加热气流、内热源加热物料、内热源加热气流、惰性固体显热加热和惰性气体显热加热,物料共有6种基本受热方式;其次,将6种受热方式组合使用时,热解过程中物料有57种类型的复合受热方式,所以将物料的受热方式归纳为63个类别。文中还分析了热解气的组分来源,以真干馏热解气为基准,给出了饱和度的定义,用于描述热解气的品质。同时,以物料受热方式和饱和度为指标,构建了热解过程的新分类体系,经进一步完善后,可用于烘焙、干馏、气化、碳化、焙烧等各类热解工程的方案设计与优化。
In this paper, a new method of classification of pyrolysis process which is independent of material type is proposed. First of all, according to the heat transfer path, the heating process of the material is divided into wall heating materials, wall heating airflow, heating materials within the heat source, heating airflow within the heat source, sensible heat of inert solid and sensible heat of inert gas. Secondly, the combination of six kinds of heating methods, the pyrolysis process has 57 types of composite material heating, so the material is heated to 63 categories. In this paper, the components of the pyrolysis gas are also analyzed. Based on the pyrolysis gas of the pyrolysis gas, the definition of the saturation is given to describe the quality of the pyrolysis gas. At the same time, a new classification system of pyrolysis process was constructed based on the material heating method and saturation. After further improvement, it can be used in the design and optimization of various pyrolysis projects such as baking, retorting, gasification, carbonization and roasting .
