Abstract

The invention discloses sintering equipment comprising a rotary kiln, a combustor and a dust removing device, wherein the rotary kiln is provided with a head end and a tail end; the combustor is connected with the head end of the rotary kiln so as to supply fuel to the rotary kiln; a smoke inlet of the dust removing device is connected with the tail end of the rotary kiln; and a dust outlet of the dust removing device is connected with the head end of the rotary kiln so as to be convenient for one part of kiln ash separated by the dust moving device to return to the rotary kiln. The sintering equipment can effectively reduce or eliminate a sintering ring in the rotary kiln and eliminate the slagging operation and has longer service life.

Description

technical field [0001] The invention relates to a sintering device, in particular to a sintering device used in the process of producing alumina. Background technique [0002] Alumina is the main raw material for electrolytic aluminum smelting. At present, the vast majority of alumina production uses bauxite as raw material. The production method is mainly Bayer method, and a few use sintering method, Bayer-sintering series method, etc. [0003] In the process of producing alumina by sintering method or Bayer-sintering tandem method, raw meal or Bayer process red mud needs to be sintered, which is traditionally sintered by sintering equipment with a rotary kiln. [0004] Rotary kiln is the main component of sintering equipment. During sintering, the rotary kiln can be divided into four zones according to the sequence of sintering materials moving in the furnace and processing, namely drying zone, decomposition zone, firing zone and cooling zone. [0005] During the sinter...
