Embodiment Construction

[0012] The present invention will be further described below in conjunction with drawings and embodiments.

[0013] The top cover 2 at the top of the kiln body is equipped with a charging port 1, and a fixed decompression cone 3 is erected in the center of the kiln body. The fire channel 4 is formed between the kiln outer wall 6 and the inner wall 8, and the interlayer between the decompression cone 3 and the inner wall 8 forms a calcining area. On the inner wall 8 of the fire channel 4 surrounding the interlayer of the calcining area, a fire port 15 is opened into the calcining interlayer, and a supporting frame 9 is installed on the position corresponding to the fire port 15 in the calcining interlayer, and the high-temperature furnace 10 is installed beside the kiln body. The furnace 10 is tangentially connected to the fire channel 4 through the ignition port 5. There is a cooling bucket 13 under the pressure reducing cone 3 in the kiln body. The bottom of the cooling bucket...

Abstract

The invention discloses a vertical interlayer cyclone direct-combustion lime kiln. A pressure relief cone (3) is vertically and fixedly arranged at the center in a kiln body; flame paths (4) are formed between the outer wall (6) and the inner wall (8) of the kiln body; a calcining zone is formed between the pressure relief cone (3) and the inner wall (8) in the manner of interlayer; flame throughholes (15) are arranged in a calcining interlayer on the inner wall (8) around the flame paths (4) of the interlayer of the calcining zone, whereas support-combustion brackets (9) are arranged corresponding to the flame through holes (15) in the calcining interlayer; high temperature furnaces (10) are respectively and tangentially connected into the flame paths (4) from ignition holes (5); and a cooling bucket (13) is arranged below the pressure relief cone (3) in the kiln body. The flame paths are arranged around the periphery of a kiln, and stones homogeneously dispersed and supported in the calcining zone are spirally and centripetally burnt, and thus, an atmosphere environment with a good combustion condition, uniform heating, heat radiation and full conduction is formed in the kiln, and meanwhile, spiral up hot air and the down stones reversely interact in the curing stroke, therefore, high-effect heat exchange with heat convection is realized.

Description

technical field [0001] The invention relates to the treatment of lime in the international patent classification C04B, and belongs to the limestone calcination technology, in particular to a vertical interlayer swirling branch-fired lime kiln. Background technique [0002] In the known technology, limestone is one of the important ores with wide application. Its processing generally requires high-temperature calcination. The chemical composition of limestone includes CaO content ≥ 53.5%. In the prior art, limestone is calcined in a kiln. Lime kiln is mainly composed of kiln body, feeding device, material distributing device, combustion device, ash unloading device, electrical appliances, instrument control device, dust removal device and so on. Calcination temperature 1000-1200℃; unit lime heat consumption: 3673kj / t; total decomposition rate of limestone ≥ 89%; dust concentration in exhaust gas ≤ 30mg / Nm 3 , The commonly used co-firing process includes: limestone and fuel a...
