摘要：

本研究在生物质流化床锅炉尾部烟气，设计了1000 t/a规模的碳捕集中试系统平台，采用“鼓泡床吸附+真空加热脱附”工艺。系统包括烟气预处理、CO₂吸附、气力输送、CO₂脱附、电控等子系统，采用撬块模式布置。运行结果显示，系统烟气进口流量550-650 Nm3/h，CO₂浓度12-15 %，经吸附后出口CO₂浓度0-0.15 %，捕集回收率达98.9 %，满足设计要求。能耗方面，系统总装机功率110.5 kW，再生热能耗小于2.07 GJ/t-CO₂，低于传统液胺技术。该系统可连续运行，操作简单，无设备腐蚀、氨逃逸等问题，为推动第二代碳捕集技术发展提供了实践参考。

Abstract:

This study designed a carbon capture pilot-scale system with an annual capacity of 1000 tons based on the flue gas from a biomass fluidized bed boiler, utilizing a "bubbling bed adsorption + vacuum heating desorption" process. The system includes subsystems for flue gas pretreatment, CO? adsorption, pneumatic conveying, CO? desorption, and electrical control, all arranged in a skid-mounted configuration. Operational results show that the system's flue gas inlet flow rate is 550-650 Nm3/h with a CO? concentration of 12-15 %. After adsorption, the outlet CO? concentration is 0-0.15 %, achieving a CO? capture and recovery rate of 98.9 %, meeting the design requirements. In terms of energy consumption, the system has a total installed power of 110.5 kW, with a regeneration thermal energy consumption of less than 2.07 GJ/t-CO?, lower than that of traditional amine-based technologies. The system can operate continuously, is easy to operate, and does not suffer from equipment corrosion or ammonia escape issues. It provides practical reference for the development of the second-generation carbon capture technologies.
