Two-way Separation of Water and Gas Pilot Equipment Based on Biomass Continuous Pyrolysis

  • 摘要:

    针对现有生物质热解设备存在的热解气中水分含量高及设备密封性差等问题,结合农业废弃物原料特征,提出了水气双向分离热解工艺方案,在此基础上,对水气双向分离热解反应器、进料和冷却出炭装置进行了专门设计,开发了水气双向分离式生物质连续热解中试设备。设备运行检测结果表明,以玉米秸秆为原料,原料处理能力27.6 kg/h,生物炭得率32.2%,热解气产率0.41 m3/kg,热解气热值15.3 MJ/m3,热解气含水率6.82%,各项技术指标均达到设备设计目标与要求。该中试设备的开发为设备示范应用提供了基础支撑。
