Annular lime shaft kiln
The invention discloses an annular lime shaft kiln. The annular lime shaft kiln comprises kiln bodies, wherein each kiln body consists of an outer ring wall and an inner ring wall, an annular cavity is formed between the inner ring wall and the outer ring wall, lintels through which the outer ring wall and the inner ring wall are connected are arranged in the annular cavity, the annular cavity is divided into a preheating zone, a calcining zone and a cooling zone from up to down, and burner nozzles are respectively arranged at the parts at the calcining zone of the outer ring wall and the inner ring wall; a distribution mechanism is arranged at the upper ends of the annular cavities, a discharging mechanism is arranged at the bottoms of the annular cavities, a feeding mechanism, a combustion supporting mechanism, a cooling mechanism and a waste-gas dust-removal system are arranged on the outer sides of the inner ring walls and the outer ring walls. The annular lime shaft kiln adopts annular structures of the inner ring walls and the outer ring walls, so that the air in the kiln bodies can be uniformly distributed, limestone can be uniformly calcined in a plurality of directions, and the phenomenon that limestone is stuck is avoided; the annular lime shaft kiln has the characteristics of being high in production efficiency, low in energy consumption, environment-friendly, safe in running, simple to operate, small in occupied area, low in investment, and the like.
