Technical field
The utility model belongs to a kind of calcining kiln, particularly the can-type calcine furnace of charcoal element production usefulness.
Background technology
Can-type calcine furnace is that the charcoal element is produced calciner commonly used, material secluding air in tank body carries out indirect heating and calcines the volatile component of removing in the carbon material, this calcining furnace can take full advantage of a large amount of volatile matters that carbon materials overflows in calcining the combustion heat reduces energy consumption, the shortcomings such as but existing can-type calcine furnace existence group number is few, air supply is not enough cause that UTILIZATION OF VESIDUAL HEAT IN is insufficient, the deficiency such as calcination efficiency and quality are low.
The utility model content
In order to overcome the low deficiency of the insufficient thermo-efficiency of existing calcining furnace UTILIZATION OF VESIDUAL HEAT IN, the utility model provides a kind of tank type carbon calciner.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of tank type carbon calciner, per four calcining tanks consist of a combustion chamber with the furnace wall of the band heating quirk that is positioned at the tank body both sides, the expansion joint is arranged between each combustion chamber and compile flue, there are at least 8 layers of quirk the furnace wall of band heating quirk, quirk communicates with the preheated air road, the calcining tank body is connecting blow-down drum, blow-down drum is with the interlayer watercooling jacket outward, it is characterized in that: totally 72 the calcining tanks in 18 combustion chambers that whole calcining furnace is arranged by yi word pattern form, the calcining furnace front wall is provided with the furnace retaining carriage outward, rear wall is provided with the furnace retaining frame outward, and the bottom, combustion chamber is supported by bottom prop, and calcining tank body top is provided with charging opening, the bottom is connecting blow-down drum, blow-down drum is with the interlayer watercooling jacket outward, and material discharging machine is equipped with in the blow-down drum lower end, is small feed bin between material discharging machine and the blow-off valve.
Be provided with the combustion of natural gas mouth that communicates with natural gas line in the front wall of described combustion chamber, the furnace wall of band heating quirk is for building the fire-resistant silica brick wall that quirk is arranged, be provided with the volatile matter passage with the bottom, combustion chamber within the walls behind the combustion chamber, the horizontal volatile matter passage that is positioned at combustion chamber bottom links to each other with the waste heat boiler flue through compiling flue, and communicates with external flue towards chimney in the flue vertical shaft that the gas fume of combustion chamber outlet is connected.
The long 2180mm of described calcining tank, wide 360mm, high 5576mm.
The disclosed can-type calcine furnace of the utility model is increased to 18 group of 72 tank with 7 group of 28 tank of traditional calcining furnace, increases to 8 layers of quirk around the calcining tank, and the tank body size changes long 2180mm into, wide 360mm, high 5576mm; The calcining furnace discharge system adopts the Full automatic closed continuous discharge device of counterflow; The direct discharge of the blow-down drum of prior art is improved to the blow-down drum mouth continuous pulp discharge machine is installed, the material of discharge is introduced into and is sent to next procedure by the blow-off valve discharge by feed belt again after small feed bin is detained buffering.Realized the two-way utilization of fugitive constituent in the can-type calcine furnace, except satisfying calcining furnace burning itself, unnecessary fugitive constituent enters waste heat boiler by designated lane, is used for generating; Because above improvement, the utility model has been obtained good effect:
1. increased output, discharge by 90 kilograms/tank/hour be increased to 150-160 kilogram/tank/hour.
2. the saving energy when normally producing, utilizes the fugitive constituent burning of raw material, fully without postcombustion.
3. unnecessary fugitive constituent is used for cogeneration, has both reduced the carbon emission amount, has effectively protected environment, meets again the Development patterns of recycling economy, for enterprise has created benefit.
4. Full automatic closed continuous discharge device of counterflow, level of automation is high, has reduced workman's labour intensity; Can make product uniform motion in calcining furnace, fugitive constituent evenly overflows, thereby so that the temperature-stable in the burner hearth guarantees constant product quality, homogeneous.According to detecting the calcined coke true density at 2.08g/cm 3More than, powder remains on below the 410 μ Ω .m than resistance.
In addition, because product is kept in motion, solved the problem of burner hearth coking, prevent scaffold and blow out phenomenon, and closed discharge has prevented effectively that then dust from overflowing, and has both reduced waste, has greatly improved again workman's work situation.
5. calcined coke cushions through small feed bin, can guarantee that calcined coke fully lowers the temperature, and effectively stops extraneous air to enter the calcining tank body, prevents that raw material from secondary oxidation and tank body occurring and blowing out phenomenon.
