Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 2, a kind of bamboo wood carbonized kiln that utilizes function with fume afterheat, comprise some some chambers 1 that form of being piled up by refractory brick, some described chambers 1 upper end is openable capping 2, described some chambers 1 comprise combustion chamber 11, preheating chamber 12 and kiln 13, in the present embodiment, be eight chambers 1, be respectively three combustion chambers 11, three preheating chambers 12, two kilns 13, described combustion chamber 11, preheating chamber 12 is connected by exhaust gases passes 3 successively with kiln 13, in described combustion chamber 11, be provided with the burning chamber 111 for placing firewood.
Described burning chamber 111 tops are provided with stone or metal plate for standing a stove on as a precaution against fire 112, and described burning chamber 111 belows are provided with fire grate 113.Stone or metal plate for standing a stove on as a precaution against fire 112 tops are used for placing retort, and described burning chamber 111 is for combustion fuel, and described fire grate 113 bottoms are for the rear lime-ash producing of fuel-in-storage burning.
Described kiln 13 is connected with smoke eliminator 4 by exhaust gases passes 3, in described smoke eliminator 4, be provided with induced draft fan 41, smoke eliminator 4 is set makes chimney 5 expellant gas can meet the requirement of environmental protection, and can by regulate induced draft fan 41 rotating speed regulate flue gas flow, thereby realize each chamber temperature regulate.
Described smoke eliminator 4 is connected with chimney 5 by exhaust gases passes 3, and chimney 5 is for being discharged to atmosphere by the flue gas after purifying.
Exhaust gases passes 3 between described combustion chamber 11 is positioned at the first half of described combustion chamber 11.Because the gas in combustion chamber 11 all can up move after heated, therefore exhaust gases passes 3 is arranged at combustion chamber 11 first halves and is relatively applicable to flow of flue gas.
Exhaust gases passes 3 between described preheating chamber 12, between described preheating chamber 12 and described kiln 13 and between described kiln 13 is interspersed in the first half and the Lower Half of described chamber 1.Because no longer heating to be therefore interspersed, the flue gas between described preheating chamber 12, between described preheating chamber 12 and described kiln 13 and between described kiln 13 can make flue gas longer in the time of chamber 1 interior stop, and the heat exchanger time between retort is elongated, heat utilization ratio is improved.
In described burning chamber 11, be provided with gas pipeline 114, gas pipeline 114 be set and replace solid fuel ignition to retort heat supply.
On described some chambers 1, be provided with the first temperature-measuring port 14.Insert thermopair at the first temperature-measuring port 14 and can record the temperature in each chamber 1, and by regulating combustible gas or solid fuel feed rate in combustion chamber 11 to carry out the temperature in control combustion chamber 11, and then control bamboo charcoal carbonization temperature; By regulating the frequency of induced draft fan 41 in smoke eliminator 4, control the flue gas flow of flow through preheating chamber 12 and kiln 13, and then control pre-carbonization temperature and the drying temperature of bamboo wood.Regulate and control by said temperature, control bamboo wood carbonized temperature between 400 ~ 900 DEG C, can realize the control of bamboo wood low-temperature carbonization, middle temperature charing and high temperature carbonization, the pre-carbonization temperature of bamboo wood is between 150 ~ 300 DEG C, and bamboo wood drying temperature is between room temperature ~ 150 DEG C.
On described chimney 5, be provided with the second temperature-measuring port 51, similarly insert thermopair at the second temperature-measuring port 51 and can record in chimney 5 flue-gas temperature, prevent the too high waste that causes heat of flue-gas temperature, and can be by the flue-gas temperature in the frequency adjustment chimney 5 of the combustible gas in adjusting combustion chamber 11 or solid fuel feed rate or induced draft fan 41.
The present invention, in the time implementing, all places a retort in each cavity, be placed with the bamboo material of different states in each retort, the fuel in ignition combustion chamber, fuel combustion heating retort.Bamboo wood in retort in combustion chamber 11 completes charing under high-temperature flue gas effect; Flue gas in front side combusion chamber 11 enters by flue in the combustion chamber 11 of rear side, and boosting is carried out in the combustion chamber 11 of rear side; Flue gas in combustion chamber 11 enters in preheating chamber 12 by flue, and high-temperature flue gas is wrapped in retort and it is conducted heat, and destructive distillation temperature in the kettle raises gradually, reaches bamboo wood carbonized condition, and bamboo wood is pre-charing in retort; Reducing and be not enough to reach bamboo wood carbonized temperature through flue-gas temperature after three preheating chambers 12, therefore enter into kiln 13 when interior at flue gas by flue, flue gas conducts heat to retort, bamboo wood carries out drying and dehydrating with this understanding, and the blower unit in smoke eliminator after kiln 13 is extracted the flue gas in kiln 13 discharge by chimney out.Thus, the present invention takes full advantage of fume afterheat, and energy utilization rate is high, and can control by the adjusting of fuel input and induced draft fan frequency the temperature of each chamber, makes bamboo wood charing at optimal temperature.
Utilize kiln of the present invention, can realize bamboo charcoal produces continuously, its technological process is as follows: after the bamboo wood carbonized in the interior retort in arbitrary combustion chamber 11 completes, the retort that bamboo wood in combustion chamber 11 is completed to charing by lifting appliance hangs out and is positioned over the outer naturally cooling of stove, again the retort in arbitrary preheating chamber 12 is hung in this combustion chamber 11, due to the pre-charing of process, the bamboo wood carbonized time in this retort can shorten greatly so; The interior retort of arbitrary kiln 13 is hung in the preheating chamber 12 that hangs out retort and carries out pre-charing simultaneously, similarly, because bamboo wood is at the red preliminary thermal dehydration of kiln 13, therefore in the time that the retort in kiln 13 hangs in preheating chamber 12, the intensification of bamboo wood and pre-carbonization process are comparatively easy; And then the retort of filling bamboo material outside kiln is hung in kiln 13.Circulation successively, produces continuously.
Be charged to bamboo charcoal discharging process from bamboo wood, fill the retort of bamboo material first in the interior heating of arbitrary kiln 13, bamboo wood hangs in after dehydration gradually and in preheating chamber 12, carries out pre-charing, then in combustion chamber 11, carries out complete charing from hanging in preheating chamber 12.Improve thus the charing efficiency of bamboo charcoal entirety, and improve the heat utilization rate of kiln.
