摘　　要：针对现有生物质热解炭化设备生产效率低、设备运行不稳定、生产连续性差及需引用外部热源加热致使耗能高等问题,采用热解可燃气回燃利用方案,设计了一种双筒回转连续式生物质热解炭化设备。详细介绍了生物质热解炭化设备的结构和工作原理,并进行热解炭化试验测试。试验表明,热解温度450℃、物料平均滞留时间30 min时,生物质热解炭化设备纯小时生产率103.8kg/h、生物炭得率34.6%和出炭温度47℃,各项性能指标均达到设计要求,可实现连续运行生产生物炭。Aiming at problems of low production efficiency,unstable equipment operation,poor production continuity and high en-ergy consumption caused by external heat source heating,a double-cylinder rotary continuous biomass pyrolysis carbonization equip-ment was designed and developed by using biomass pyrolysis carbonization scheme of pyrolysis combustible gas reburning.Structure and working principle of pyrolysis carbonization equipment were introduced in detail,and pyrolysis carbonization test was carried out with corn straw as raw material.Test results showed that pyrolysis temperature was 450℃,average residence time of material was 30 min,pure hour productivity of carbonization equipment was 103.8 kg/h,biochar yield was 34.6%,and carbon temperature was 47℃.All performance indexes met design requirements,and continuous operation of biochar production could be realized.
