Abstract
The utility model relates to an internally heated carbonization and activation furnace. The furnace body of the internally heated carbonization and activation furnace is divided into a carbonation furnace and an activation furnace; the carbonation furnace is positioned above the activation furnace; both the carbonization furnace and the carbonation furnace are provided with transmission wheels and rotating wheels; the carbonization furnace is connected with a carbonization furnace tail gas passage; the activation furnace is connected with an activation furnace tail gas passage; the carbonization furnace is communicated with an external hot flue; the tail end of the carbonization furnace is connected with a gravity conveying passage; and the carbonization furnace is communicated with the activation furnace through the gravity conveying passage. By using the internally heated carbonization and activation furnace, both the temperature and the energy consumption of the furnace head can be reduced, and active carbon is produced under a low temperature condition, so that the consumption of phosphoric acid is reduced; and experimental data shows that the average unit consumption is reduced by 0.1-0.2 ton of phosphoric acid per ton of active carbon and meanwhile the quality of the active carbon is also effectively improved.
Description
Technical field
The utility model relates to a kind of internal heat type carbon activation furnace, relates in particular to phosphoric acid method and makes equipment in the gac.
Background technology
At present, what activated carbon of phosphoric acid method mainly adopted is the converter of internal heat type charcoal activation integral, the main drawback that it exists is: the one, and the excess Temperature of burner is generally about 600-800 ℃, and the optimum temps that generates with evidence gac hole after deliberation is about 450 ℃, rising along with the charcoal activation temperature, thereby gac can be lost the adsorptive power that causes gac by burning in various degree to descend, so the optimum temps of phosphoric acid method activation is generally best about 450 ℃.The 2nd, the charcoal activation of activated carbon of phosphoric acid method is an endothermic process, and being main endothermic phase, the charing stage accounts for 80% of whole endothermic process institute heat requirement, therefore temperature can sharply reduce along with the activation carbonization process in the production of charcoal activation integral, and the length of soak time depends on activation temperature, activation temperature is higher, soak time is shorter, thus charcoal activation integral stove must under hot conditions, just can make the activation finish more abundant.The 3rd, the higher phosphoric acid of temperature can be burnt lose more, and therefore acid consumption can be higher.
Summary of the invention
The purpose of this utility model provides temperature and the energy consumption that can reduce burner, reduces phosphoric acid consumption, a kind of internal heat type carbon activation furnace of Effective Raise quality of activated carbon.
The technical scheme that the utility model is taked is: a kind of internal heat type carbon activation furnace, it is characterized in that body of heater is divided into charring furnace and activation furnace, charring furnace is positioned on the activation furnace, be equipped with power wheel and rotor wheel on charring furnace and the activation furnace, be connected with the tail gas of carbonization stove road on the charring furnace, be connected with the activatory furnace exhaust gas road on the activation furnace; Charring furnace interlinks with the hotflue of outside, and the end of charring furnace is connected with the gravity transfer road, interlinks by the gravity transfer road between charring furnace and the activation furnace.
Adopt the utility model, can reduce temperature and the energy consumption of burner, and under cold condition, produce gac, thereby phosphoric acid consumption has been reduced, test factually data and show, average quantity used in unit volume blasted has reduced by 0.1～0.2t phosphoric acid/t gac, also effectively improves simultaneously quality of activated carbon.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Sequence number represents among the figure: charring furnace 1, power wheel 2, rotor wheel 3, tail gas of carbonization stove road 4, gravity transfer road 5, activation furnace 6, activatory furnace exhaust gas road 7, handling machinery 8, hotflue 9.
Embodiment
The utility model is described in further detail below in conjunction with specific embodiment.
With reference to Fig. 1, the body of heater of this internal heat type carbon activation furnace is divided into charring furnace 1 and activation furnace 6, and charring furnace 1 is positioned on the activation furnace 6, is equipped with power wheel 2 and rotor wheel 3 on charring furnace 1 and the activation furnace 6, be connected with tail gas of carbonization stove road 4 on the charring furnace 1, be connected with activatory furnace exhaust gas road 7 on the activation furnace 6; Charring furnace 1 interlinks with the hotflue 9 of outside, and the end of charring furnace 1 is connected with gravity transfer road 5, interlinks by gravity transfer road 5 between charring furnace 1 and the activation furnace 6.
Wherein, the size of activation furnace 6 is generally about 1/2nd of charring furnace 1 size, because the heat that needs at activation section is 1/4th of charing section institute heat requirement.During use, the wood chip that phosphoric acid is kneaded is by handling machinery 8(spiral conveyer) send charring furnace 1 to, charring furnace 1 is under power wheel 2 and rotor wheel 3 drives and effect, according to certain rotational speed, to guarantee that impregnated wood chip has more uniform heat to enter, thereby guarantee that charing can fully carry out, the heat of charring furnace 1 is to be provided by hotflue 9.The tail gas of charring furnace 1 enters recovery system through tail gas of carbonization stove road 4.The carbonized material that charing is good is entered in the activation furnace 6 by gravity transfer road 5 and activates.The tail gas of activation furnace 6 enters recovery system through activatory furnace exhaust gas road 7.The temperature of charring furnace 1 remains between 100～500 ℃, and the temperature of activation furnace 6 remains between 350～500 ℃.
In above-mentioned, this internal heat type carbon activation furnace greatly reduces the activation temperature of activated carbon of phosphoric acid method, make 600～800 ℃ of original end flue temperatures be reduced to 500 ℃, thereby make quality inferior blue adsorptive power under identical condition of gac improve 1～3mL, Caramel adsorption has improved 20～50%.Owing under cold condition, producing, both reduced phosphoric acid consumption, show according to test data, average quantity used in unit volume blasted has reduced by 0.1～0.2t phosphoric acid/t gac, compares with traditional integrated furnace again simultaneously and has reduced energy consumption.In addition, effectively solved the contradiction of gac output and quality of activated carbon, because generally higher owing to output is required in the production of present charcoal activation integral converter, so activation temperature improves in a part of factory for output, thereby quality of activated carbon is descended.And this production unit makes charcoal, activation separately, and different pyrolytic processs makes gac output and quality reach unification in two processes thereby utilized fully.
