Recycling method of high-titanium blast furnace slag
The invention belongs to the technical field of comprehensive utilization of metallurgical solid waste resources, particularly discloses a recycling method of high-titanium blast furnace slag, and aims to solve the problem of how to recycle sensible heat resources of the high-titanium blast furnace slag. According to the recycling method of the high-titanium blast furnace slag, liquid-state high-titanium blast furnace slag at the temperature of 1200-1350 DEG C is cast into high-temperature slag blocks at the temperature of 900-1000 DEG C through a slag casting plate, and then the high-temperature slag blocks are intermittently added into a heat exchange tank for heat exchange through cold air flowing from bottom to top in the heat exchange tank; after heat exchange, cold air becomes hot air and is used for power generation of power generation equipment or material drying, so that sensible heat resources of the high-titanium blast furnace slag can be fully recycled, and the utilization rate reaches 40% or above.
本发明属于冶金固废资源综合利用技术领域，具体公开了一种高钛型高炉渣的回收利用方法，旨在解决如何回收利用高钛型高炉渣的显热资源的问题。该高钛型高炉渣的回收利用方法，通过利用铸渣板将温度在1200～1350℃的液态高钛型高炉渣铸造为900～1000℃的高温渣块，再将高温渣块间歇式加入换热罐中通过换热罐内由下往上流动的冷风进行换热；换热后，冷风变为热风并用于发电设备发电或物料干燥，可使得高钛型高炉渣的显热资源得到充分回收利用，利用率达到40％以上。
