鸡粪超临界水氧化工艺特性与经济性分析OA
Operating and Economic Analyses of Supercritical Water Oxidation Process for Chicken Manure
为更好实现废物的高效处置和能源化利用,采用Aspen Plus对鸡粪超临界水氧化工艺进行模拟,并分析系统的能量转化和运行特性.结果表明:新型超临界水氧化系统的 效㶲优于基于传统水膜反应器的超临界水氧化系统,而燃烧反应器和氧化反应器是该系统 损㶲的最主要来源,分别占24.49％和18.62％;系统 效㶲随反应温度和鸡粪浆液质量分数的提升有所升高;鸡粪超临界水氧化的净处理成本为211.54元/t.利用易燃型高浓度有机废液替代燃料可实现废物协同处理,获得更显著的经济效益.
Supercritical water oxidation of chicken manure was simulated using Aspen Plus,and the energy conversion and operating characteristics of the process were analyzed to achieve efficient disposal and energy utilization.Results indicate that,the efficiency of the new system is better than those with traditional transpiring wall reactors.The combustion reactor and oxidation reactor are the main sources of exergy loss in the system,accounting for 24.49％and 18.62％,respectively.The exergy efficiency increases with the increases of reaction temperature and mass fraction of chicken manure slurry.The net treatment cost of supercritical water oxidation of chicken manure is 211.54 yuan/t.The use of flammable high concentration organic wastewater as a substitute for fuel can achieve a collaborative disposal of waste and obtain more significant economic benefits.
