Abstract
The present application provides a lime kiln apparatus recycling CO2 which includes a kiln body (100) and a heat-accumulating furnace set (20). The kiln body (100) defines no burner therein, and the heat-accumulating furnace set (20) provides hot CO2 (70) heated to a set temperature to the kiln body (100) for calcining mineral material, thereby finished lime is obtained. CO2 generated during the lime production is all recycled. After being dedusted, a part of the recycled CO2 is transported to the heat-accumulating furnace set (20) for heating, and is sent back to the kiln for calcining the mineral material after being heated to a temperature within a range of 800° C.-1200° C., and the other part of the recycled CO2 is recycled for use.
