The flue gas discharge opening 2-1 gone out, the upper end of described flue 3 is provided with carbonizing gas outlet 3-1 discharged for carbonizing gas.
In the present embodiment, wooden raw material in use, is first seated in flue 3, then passes through by this dry distillation carbonizing furnace
Flue 3 is lifted in described body of heater 2 by the mode of lifting, and is tightly connected, then in the upper end of flue 3 and the upper end of body of heater 2
Being that described flue 3 heats by described burning heater, the flue gas that described burning heater produces can enter flue 3 and stove
Temperature gap is added, it is also possible to realizing heating flue 3 sidewall, now, described flue 3 sidewall is heated, diapire is subject between body 2
Heat, is so capable of the most indirectly heating raw material wooden in flue 3, and meanwhile, the flue gas in body of heater 2 is arranged by flue gas
Outlet 2-1 discharges, and the carbonizing gas produced in flue 3 is discharged by carbonizing gas outlet 3-1.
In the present embodiment, this dry distillation carbonizing furnace is in use, it is possible to will fill wooden raw-material flue 3 and directly hang in
Carry out heating dry distilling in body of heater 2, after heating terminates, then flue 3 is hung out from body of heater 2 cooling, then to next stove
Gallbladder 3 carries out heating dry distilling, i.e. forms Linesless charcoal finished product, entered the wooden raw material in flue 3 by this in the flue 3 after cooling
In the ranks connect the mode of heating, and flue 3 is lifted or hung out the mode of described body of heater 2, be effectively increased dry distillation efficiency.
In the present embodiment, described pedestal 1 is the tubular structure become with laying fireproof bricks.By arranging air intlet thereon
1-1 and for controlling the regulation door 1-2 of described air intlet 1-1 openings of sizes, it is possible to be effectively the combustion heating confession of flue 3
Oxygen, and oxygen-supplying amount can be adjusted by it by described regulation door 1-2, to realize being adjusted flue 3 combustion heating.
Have for separating wood vinegar in carbonizing gas, wood tar as it is shown in figure 1, described carbonizing gas outlet 3-1 connects
Carbonizing gas processing means with wood gas.By arranging described carbonizing gas processing means, it is possible at carbonizing gas
Reason, makes the wood vinegar in carbonizing gas, wood tar and wood gas efficiently separate out from carbonizing gas, and wooden raw material is done
When evaporating, the carbonizing gas of generation is mainly composed of wood vinegar, wood tar and wood gas.
As it is shown in figure 1, described carbonizing gas processing means includes for cooling down carbonizing gas and then making wood vinegar therein
The gas cooler 12 separated with wood tar, carbonizing gas outlet 3-1 of described flue 3 is by carbonizing gas conveying pipe
5 are connected with the cooler air inlet 12-1 of gas cooler 12, and aqueous vapor outlet 12-2 of described gas cooler 12 connects
There is the aqueous vapor discharge pipe 9 for discharging wood gas and steam, described aqueous vapor discharge pipe 9 is provided with aqueous vapor discharge pipe shut-off valve

In conjunction with Fig. 1 and Fig. 4, the flue 3 of this dry distillation carbonizing furnace is after being heated, and its interior temperature gradually rises, pressure also by
Cumulative height, the temperature in flue 3 is increased in 270 DEG C of these temperature ranges, and the predominantly water vapour in carbonizing gas is with few
Amount wood gas, containing the side-product composition such as wood tar and wood vinegar in steam, in the process due to the carbonizing gas produced
Can not light, carbonizing gas now processes, at gas in entering into gas cooler 12 by carbonizing gas conveying pipe 5
Wood vinegar and wood tar aqueous vapor etc. is separated out bottom gas cooler 12 through wood tar due to carbonizing gas cooling in cooler 12
And wood vinegar discharge pipe 20 is drained into separate tank, in separate tank, wood tar is layered owing to density is different with wood vinegar moisture content, thus
Realizing separating, in carbonizing gas, remaining water vapour and a small amount of wood gas are through aqueous vapor outlet 12-2 of gas cooler 12 warp
Aqueous vapor discharge pipe 9 is discharged, and now xyloid coal letter shoot shut-off valve 14 is closed, and uses common combustion due to now general
Material, the flue gas produced in body of heater 2 is taken away through blower fan 11 and is emptied by smoke discharge pipe 10 after flue gas cleaner 17 processes.Pass through
Heating-up temperature constantly raises, and when the temperature in flue 3 is increased to more than 270 DEG C, the wood gas concentration now produced can be lighted,
Now turning off aqueous vapor discharge pipe shut-off valve 8, open xyloid coal letter shoot shut-off valve 14, carbonizing gas purifies through gas cooler 12
Wood gas after process is from wood gas outlet 12-3 and is delivered to described burning heater through xyloid coal letter shoot 13 and sentences
Use as fuel, until the temperature in flue 3 rises to 400 DEG C, i.e. hang in dry distilling from flue 3 and complete average about 6 hours.By
In use wood gas as fuel, in body of heater 2 now flue gas be mainly composed of carbon dioxide, cleaner, can turn off
Flue gas delivery pipe shut-off valve 7, is directly emptied flue gas by flue gas evacuated tube 21.
In the present embodiment, by arranging described carbonizing gas processing means, it is possible to carbonizing gas is efficiently separated
Processing, and make the wood gas separated can serve as the heating fuel of flue 3, it has effectively saved the energy, and xyloid coal
The flue gas produced after gas firing is cleaner, it is possible to directly empties, decreases the pollution to environment.By arranging flue gas cleaner
17, it is possible to the flue gas that in body of heater 2, other fuel combustion produces in addition to wood gas is carried out purified treatment, and then avoids flue gas straight
Run in sky and cause environmental pollution.
