How to Treat Lime in Environmental Protection Lime Kiln

Environmental protection lime kiln can not only protect the environment, but also produce lime with good quality and low cost. For enterprises adopting this new technology, the economic benefits will be significantly improved. This is the practical significance of promoting the new technology of lime kiln.

Due to the increasing demand for lime in the steel industry, the soil and lime kiln in the market began to operate. However, the production process and product quality of the old kiln can no longer meet the needs of modern production, with low product activity, uncontrollable burning and overburning, and serious environmental pollution caused by fuel waste. Therefore, the new environmental protection lime kiln production line has been widely used because of its good production technology level. The following environmental protection lime kiln manufacturer introduces the working principle of the environmental protection lime kiln production line:

The qualified limestone is hoisted by the elevator and transported to the top bin of the preheater. The top bin controls the feeding amount, and then distributes limestone evenly to each chamber of the preheater through the feeding pipe. Limestone is heated to about 900 ° C in the preheater, about 30% of which is decomposed, and pushed into the rotary kiln by the hydraulic push rod. Limestone is calcined and decomposed into calcium oxide and carbon dioxide in the rotary kiln. The limestone generated after decomposition enters the cooler and is cooled to 100 ° C by the cold air pumped in.

The hot air enters the kiln for heat exchange and mixed combustion with the gas. The waste gas is cooled by the multi pipe cooler, enters the bag type dust remover through the induced draft fan, and then enters the chimney through the exhaust fan.

Lime from the cooler is sent to the finished lime silo successively through vibrating feeder, conveyor, elevator and other equipment.

The high energy efficiency of ash discharge from environmental protection lime kiln is related to the improvement of production efficiency and the realization of environmental protection purposes.
