- 以市政污泥为原材料，通过造粒和热解工艺成功合成污泥基生物炭材料，并以其为载体，通过浸渍负载相变芯材聚乙二醇，制备聚乙二醇/污泥基生物炭复合相变蓄热调理剂。通过扫描电子显微镜、傅里叶变换红外光谱分析、热重分析、差示扫描量热和微量热分析等手段对其进行结构表征及性能测试。结果表明，所制备的污泥基生物炭蓄热调理剂具有稳定的相变储热能力，负载聚乙二醇的质量分数达到77.9%，熔融潜热为45.65 J/g，表现出良好的定形相变效果和循环稳定性，能够促进微生物放热，可用于提升生物干化系统效率。
- Abstract:
- Municipal sludge was used as the raw material to successfully synthesize sludge-based biochar through granulation and pyrolysis. The obtained biochar served as a carrier, into which polyethylene glycol (PEG) was impregnated and loaded as the phase-change core material, yielding a PEG/sludge-based biochar composite phase-change heat-storage conditioner. The structural characteristics and thermal performance of the prepared material were investigated using scanning electron microscopy, Fourier-transform infrared spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and microcalorimetry. The results indicated that the prepared sludge-based biochar heat-storage conditioner exhibited stable phase-change thermal storage capability. The mass fraction of loaded PEG reached 77.9%, with a melting latent heat of 45.65 J/g, demonstrating favorable shape-stabilized phase-change behavior and cyclic stability. Furthermore, it could promote microbial heat release and thus enhance the efficiency of bio-drying systems.
