Abstract

The invention discloses a feeding method for alumina clinker sintering and related equipment, relates to the technical field of material processing, and can solve the problems that the denitration efficiency of exhaust gas discharged by an existing alumina rotary kiln is low, and the content of nitric oxide in the discharged exhaust gas is difficult to reach the standard. The feeding method for alumina clinker sintering comprises the following steps: spraying hot flame into a sintering cavity of an alumina clinker rotary kiln; the spraying amount of the slurry close to the flue is controlled to be smaller than the spraying amount of the slurry away from the flue, and the slurry sprayed into the sintering cavity is used for heat exchange with the hot flame.

Description

technical field [0001] The present application relates to the technical field of material processing, and in particular, to a feeding method and related equipment for alumina clinker sintering. Background technique [0002] At present, the alumina rotary kiln adopts wet feeding method. The heat exchange between the hot air injected into the rotary kiln and the slurry injected into the rotary kiln can easily cause the temperature of the exhaust gas from the rotary kiln to drop rapidly, resulting in the discharge from the rotary kiln. The temperature of the exhaust gas is low, resulting in a low efficiency of exhaust gas denitration, and the nitrogen oxide content of the exhaust gas is difficult to meet the standard. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a feeding method and related equipment for alumina clinker sintering, which can improve the problems of low denitration efficiency of the exhaust gas discharged from the existin...
