During operation, treat the raw material of carbonization through conveyer from the charging aperture 1 of the kiln head cover 2 of described retort Enter in inner barrel 3, and along with the rotation of inner barrel 3 is moved to kiln tail from kiln hood.Meanwhile, The high-temperature hot flue gas produced through burner 8 burning respectively enters in corresponding segmentation chuck 9, inwardly Heat supply in cylinder, in order to material carbonization.Heat smoke after heat supply after through the row of each segmentation chuck 9 QI KOU is sent;In inner barrel, the material after carbonization is discharged from kiln hood 5, produced by carbonization reaction Combustible fumes is then sent from kiln head cover 2, such as, enter incinerator 7 burning and reclaim heat.
By embodiment, this utility model is described further below.
Embodiment
Use retort as shown in Figure 1, during operation, treat that carbonization raw material is (former through pre-oxidize Material coal) enter in inner barrel 3,6 chuck sections (from kiln through charging aperture 1 by kiln head cover 2 Head be respectively the first chuck section to the 6th chuck section to kiln tail) set by burner heat supply under carry out Carbonization, the waste gas in chuck section is discharged from air vent.Material is rotating according to predetermined thermograde Inner barrel in uniformly heat, the carbonizing production obtained is discharged from the discharge gate of kiln hood.Carbonization is anti- Extraction should be exported through the combustible gas of kiln head cover 2 by produced combustible gas, send incinerator 7 burning to utilize.
Concrete, raw coal size 3~8 mesh, in controlling in inner barrel corresponding to the first chuck section Between temperature be 360~380 DEG C, the medium temperature controlled in inner barrel corresponding to the second chuck section is 430~450 DEG C, control the 3rd chuck section, the 4th chuck section, the 5th chuck section and the 6th chuck section institute Medium temperature in corresponding inner barrel is respectively 480~520 DEG C, carbonization time 2 hours.
Carbonizing production: bulk density~716g/L, intensity~97.5%, yield~68.6%.
Comparative example
Using tradition internal heat type retort to carry out carbonization, feed coal ibid, is 900 DEG C with inlet temperature High-temperature flue gas as thermal source, carbonization time 2 hours.
Carbonizing production: bulk density 670g/L;Intensity 93.7%, yield 62.5%.
From the foregoing, it can be understood that carry out carbonization by segmentation external-heat carbonizing apparatus, make through pre-oxidation Feed coal granule carries out low temperature pyrogenation, and gained carbonized material intensity, yield and bulk density are all obviously improved.
