摘要：为减少中药渣堆存对环境的污染,采用循环流化床锅炉技术对中药渣进行资源化利用研究。根据中药渣基本特性,采用"动态仓储缓存-机械压滤脱水-太阳能温室干燥-循环流化床锅炉燃烧"的工艺方案,对中药渣进行处理,分析中药渣在循环流化床中燃烧锅炉设计参数、燃烧过程、床压控制、药渣含水率对炉膛温度和尾部烟道温度的影响、返灰量补充、环保指标等,并对药渣处理的效益进行评估。结果表明:中药渣作为生物质燃料进入循环流化床锅炉燃烧,产生的蒸汽再作为中药提取原料,形成一个闭合循环;该处理过程具有良好的经济效益和环保效益。

Abstract: In order to avoid the pollution to the environment caused by the traditional Chinese herb residue，the technology of circulating fluidized bed (CFB) was used to recycle it in a resource-based way．According to the basic characteristics of Chinese herb residue，the industrial solution of stored in mixing bin－filtered by mechanical pressure－dried by solar thermal energy in greenhouse－burned by circulating fluidized bed boiler was selected，and important burning process data was analyzed at the same time，including boiler design parameters，bed pressure control parameters，change trend of temperature in boiler furnace and tail flue with moisture content of herb residue，the effective measure of adding ash to adjust burning process，the environmental indicators and so on．Finally，benefits of this Chinese herb residue treatment were evaluated．The results show that Chinese herb residue is burned as bio-fuel in CFB boiler and produce steam for herb extraction producing，forming a reasonable closed recycle well．
