Method for preparing active mineral admixture through suspension roasting of industrial solid waste
The invention discloses a method for preparing an active mineral admixture through suspension roasting of industrial solid waste. During production, the material flow trend is as follows: vanadium slag, stone coal and limestone are uniformly mixed and then sequentially enter a P1 suspension preheater, a P2 suspension preheater and a P3 suspension preheater through an elevator for preheating, decomposition and solid-phase reaction; the mixed material enters a roasting furnace to be sintered, the sintered material enters a gas-solid separator to generate an active mineral admixture, the active mineral admixture sequentially enters a cooler C2, a cooler C1 and a heat exchanger to be further subjected to heat exchange, and the active mineral admixture is conveyed to a finished product warehouse; during production, the airflow trend is as follows: a high-temperature fan generates running airflow, cold air in a heat exchanger sequentially enters a C1 cooler and a C2 cooler, hot air enters a roasting furnace, and hot flue gas of the roasting furnace sequentially enters a gas-solid separator, a P3 suspension preheater, a P2 suspension preheater and a P1 suspension preheater; the invention has the advantages of energy conservation, consumption reduction, low calcination temperature, good stability of the high-temperature sintered mineral admixture, less formula, simple process and small environmental pollution.
一种悬浮焙烧工业固废制备活性矿物掺合料的方法，生产时料流走向：钒渣、石煤、灰岩混合均匀后经提升机依次进入P1悬浮预热器、P2悬浮预热器、P3悬浮预热器内预热、分解和固相反应；混合料进入焙烧炉内进行烧结，烧结后的物料进入气固分离器内，生成活性矿物掺合料，活性矿物掺合料依次进入C2冷却器、C1冷却器、换热器内进一步换热，活性矿物掺合料送至成品库；生产时气流走向：高温风机产生运行气流，换热器内的冷空气依次进入C1冷却器、C2冷却器，热空气进入焙烧炉，焙烧炉的热烟气依次进入气固分离器、P3悬浮预热器、P2悬浮预热器、P1悬浮预热器；本发明节能降耗，煅烧温度低、通过高温烧结矿物掺合料稳定性好，配方少、工艺简单，环境污染小。
