CO2 zero-emission production process and system for calcining limestone by using solar energy
The invention discloses a CO2 zero-emission production process and system for calcining limestone by using solar energy, and the specific process is as follows: solar energy is reflected to a heat collection and energy storage device through a mirror field, the heat collection and energy storage device focuses and stores energy, the collected kiln tail waste gas containing high-concentration CO2 gas is heated to 900-1200 DEG C, and is conveyed into a decomposing furnace for calcining and decomposing limestone, and then the limestone is calcined and decomposed. After high-concentration CO2 waste gas generated by limestone decomposition in the decomposition furnace enters a preheater system to preheat limestone, the high-concentration CO2 waste gas returns to the heat collection energy storage device; and the decomposed calcium oxide is cooled to 80-100 DEG C through a cyclone cooler in an independent cold air supply mode. According to the invention, low-energy-consumption, low-pollution and low-emission solar clean energy is used for replacing high-energy-consumption, high-pollution and high-emission traditional energy such as coal, petroleum and the like, and zero emission of CO2 is realized.
本发明公开了一种利用太阳能煅烧石灰石的CO2零排放生产工艺及系统，具体工艺为太阳能通过镜场反射到集热储能器上，集热储能器聚焦并储存能量，将收集的含高浓度CO2气体的窑尾废气加热至900～1200℃，并输送到分解炉内锻烧分解石灰石，分解炉内石灰石分解产生的高浓度CO2废气进入预热器系统预热石灰石后，再返回到集热储能器中；分解后的氧化钙采用独立供应冷风的方式通过旋风冷却器进行冷却至80～100℃。本发明以低能耗、低污染、低排放的太阳能清洁能源替代煤炭、石油等高能耗、高污染、高排放的传统能源，并实现CO2零排放。
