医疗垃圾热解气化研究

Modeling Study on Pyrolysis of Medical Wastes

利用热解动力学原理,建立热解过程转化率模型。并耦合非稳态导热方程建立传热模型,共同构建垃圾热解过程的数学模型。采用TDMA算法编制模拟计算程序。对典型运行工况下垃圾内部温度场的变化规律进行模拟。结果表明,模拟值与实测值具有相同的变化规律,所建数学模型可以用来研究垃圾在外热式热解炉内的热解规律。

Coupled with the heat-transfer model and based on pyrolysis dynamics theory,the mathematic model of solid waste pyrolysis was built up. Simulating the changes of temperature of solid wastes,the modeling showed the results similar to the real experimental ones.
