Description

technical field [0001] The invention relates to the technical field of resource utilization of municipal solid waste, and more specifically relates to a microwave-driven hydrothermal carbonization reactor device and method for municipal solid waste. Background technique [0002] Municipal solid waste contains huge renewable low-grade energy. Scientific and reasonable disposal of municipal solid waste not only avoids secondary pollution, but also realizes resource utilization and energy utilization. However, municipal solid waste has the characteristics of low energy density and high initial moisture content. How to realize high-efficiency energy conversion of municipal solid waste from the source and high-value utilization of products has become a research hotspot in recent years. [0003] The development of hydrothermal carbonization technology provides a new way to realize the efficient resource utilization of biomass waste. Hydrothermal carbonization technology makes ful...

AI Technical Summary

Problems solved by technology

[0004] Existing hydrothermal carbonization equipment usually uses high-temperature and high-pressure reactors, and the heating mode is traditional electric heating, which leads to long time-consuming hydrothermal carbonization experiments or experimental research, and large heat loss from the external body, which is not conducive to giving full play to the advantages of hydrothermal carbonization technology. It is suitable for laboratory experiments and research on hydrothermal carbonization driven by municipal solid waste
