水煤浆气化炉渣的特性分析及应用探讨

Characteristic Analysis and Application Discussion of Coal Water Slurry Gasifier Slag

为达到煤化工气化炉炉渣资源化、减量化和无害化利用目的,需要寻找一条高效综合利用气化渣的技术路线。研究了气化炉渣的粗渣和细渣的粒度分布、工业分析、密度、形貌和化学组成等特性,发现气化渣粗渣容易实现分选,获得高热值燃料和无机颗粒用于建材产品。而气化细渣水分含量高,通过粒度分选不易分离,需要其他工业分离技术进一步分离以获取高热值产品。

In order to achieve the goal of resource utilization,reduction and harmless utilization of gasifier slag in coal chemical industry,it is necessary to find a technical route for efficient comprehensive utilization of gasification slag.This paper studied the particle size distribution,industrial analysis,density,morphology and chemical composition of coarse slag and fine slag of gasifier slag.It is found that coarse slag of gasification slag can be easily separated,and high calorific value fuel and inorganic particles can be obtained for building materials.However,gasification fine slag has high moisture content,which is difficult to be separated by particle size separation,and needs further separation by other industrial separation technologies to obtain high calorific value products.
