摘要
在目前通用的水煤浆气化炉工艺烧嘴和干煤粉气化炉工艺烧嘴的基础上,分别提出了新型的工艺烧嘴结构,并对使用两种新型气化炉工艺烧嘴协同处置煤化工废水废液的相关问题进行了分析探讨,主要包括工艺烧嘴结构、煤化工废水废液对气化工艺的影响、煤化工废水废液对工艺烧嘴使用寿命的影响等几方面内容.分析研究结果表明:通过Aspen Plus工艺流程模拟软件的计算,采用新型结构的水煤浆工艺烧嘴协同处置某煤化工企业含水量较高的吡啶废水,会造成合成气中有效气含量略有降低,建议采取相应措施消除上述影响;采用新型粉煤工艺烧嘴协同处置煤化工废水废液,若废水废液处置量和原有工艺烧嘴蒸汽消耗量相当,则不会对气化工艺有明显影响.
Abstract
On the basis of the commonly used process burners for coal water slurry gasifiers and dry pulverized coal gasifiers,new process burner structures were proposed respectively,and the relevant issues of using two new gasifier process burners for co-processing of coal chemical wastewater and waste liquid were analyzed and discussed,mainly including process burner structure,the impact of coal chemical wastewater and waste liquid on gasification process and service life of process burners,etc.The analysis results showed that,through the calculation with Aspen Plus process simulation software,using new structure of coal water slurry process burner for co-processing of pyridine wastewater with high water content in a coal chemical enterprise would cause a slight decrease of the effective gas content in the syngas.It was recommended to take corresponding measures to eliminate the above effects.When a new type of pulverized coal process burner was used for co-processing of coal chemical wastewater and waste liquid,if the treatment amount of wastewater and waste liquid was equivalent to the steam consumption of the original process burner,it would not have a significant impact on the gasification process.
