Abstract

The invention relates to a large rotary kiln system and a working method thereof. The large rotary kiln system comprises a rotary kiln, a preheater system, a material sliding trolley and a material cooling system. The rotary kiln is provided with a two-gear support; the preheater system comprises a material distribution bin, a preheater body and a material pushing system; a material sliding vehicle is arranged between a feed opening in the bottom of the preheater system and an inlet of the rotary kiln; the top of the material cooling system is connected with an outlet of the rotary kiln, a discharging port is formed in the bottom, and a cooler with an external air chamber is arranged in the material cooling system. The method is used for calcining active lime or light-burned dolomite; a two-gear supported large rotary kiln is used as core equipment, a preheater system is arranged at the front end of the system, a material cooling system is arranged at the rear end of the system, and other related corollary equipment are added to jointly form a large rotary kiln system; as an advanced technology for leading green development of the iron and steel industry, the method has remarkable comprehensive benefits and advantages in the aspects of increasing the resource utilization rate, improving the lime quality, saving energy and the like.

Description

technical field [0001] The invention relates to the technical field of rotary kilns, in particular to a large-scale rotary kiln system and a working method thereof. Background technique [0002] Active lime is an important auxiliary material for industrial production, widely used in chemical industry, calcium carbide, alumina, papermaking, environmental protection and many other industries. The active lime produced by rotary kiln has the characteristics of uniform calcination and stable product quality. From the 1970s to the beginning of this century, my country's lime rotary kiln production lines were limited to a few large iron and steel enterprises, but the proportion of total production capacity was low, and the output of a single kiln was low, making it difficult to form economies of scale. Therefore, it is urgent to develop a large-scale lime rotary kiln system. [0003] The invention provides a large-scale rotary kiln system supported by two gears, which is used for...
