A kind of biologic grain carbonizing apparatus
Technical field
The utility model is related to charring process field, a kind of specific biologic grain carbonizing apparatus.
Background technology
Using biomass carbonizing furnace, molding biologic grain or crushed biomass can further be carbonized, produce charcoal,
Charcoal combustion efficiency significantly improves, and pollutant load when burning in flue gas is substantially reduced, and is a kind of high-grade civilian combustion
Material, good charcoal can be also used for metallurgical industry.Therefore, during producing charcoal with retort how effectively,
Adequately discharge combustion gas, tar improve the quality of final finished charcoal for improving biologic grain carbonization reaction rate even
There is important influence.
Currently, existing carbonizing apparatus is usually to install exhaust outlet in the side of reacting furnace gas, this design is discharged
Keep the local carbonization reaction close from exhaust outlet fast, the local carbonization reaction remote from exhaust outlet is slow, and very possible carbonization reaction is not
Completely, the exhaust gas that carbonization reaction generates also is expelled directly out via exhaust outlet, has prodigious pollution to environment.
Invention content
The technical problems to be solved in the utility model is to provide a kind of biologic grain carbonizing apparatus, can purify and carbonize instead
The exhaust gas that should be generated accelerates the circulation of gas, keeps carbonization reaction abundant, to solve the problems mentioned in the above background technology.
The utility model is realized in this way：A kind of biologic grain carbonizing apparatus, including preheating cabinet, charing case, cooler bin
And conveyer belt, the conveyer belt are worn inside the preheating cabinet, charing case and cooler bin；The preheating cabinet bottom is installed with
Air-heater, the preheating cabinet top are installed with feed hopper, and ground terminal is installed with charing heater box inside the charing case,
The charing box top is installed with air inlet pipe, and one end of the air inlet pipe is installed with waste gas purification apparatus, described useless
Air purifying apparatus side is installed with exhaust fan, and active carbon filter screen is installed with inside the waste gas purification apparatus.
Preferably, the cooler bin bottom is installed with holder.
Preferably, the output end of the side wall of the cooler bin and the corresponding conveyer belt is installed with a discharge bucket.
Compared with prior art, the utility model has the beneficial effects that：
1, the utility model, it is simple in structure, reliable, of low cost and efficient；
2, active carbon filter screen can effectively purify exhaust gas, tar, and of low cost；
3, exhaust fan can be accelerated to carbonize the flowing of case inner air, accelerate carbonization reaction.
Description of the drawings
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure：1 preheating cabinet, 2 charing casees, 3 cooler bins, 4 air-heaters, 5 conveyer belts, 6 feed hoppers, 7 exhaust fans, 8 exhaust gas are net
Makeup set, 9 air inlet pipe, 10 charing heater boxes, 11 discharge buckets, 12 active carbon filter screens
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to Fig. 1, the utility model provides a kind of technical solution：This kind of biologic grain carbonizing apparatus, including preheating cabinet
1, case 2, cooler bin 3 and conveyer belt 5 are carbonized, the conveyer belt 5 is worn inside the preheating cabinet 1, charing case 2 and cooler bin 3；Institute
It states 1 bottom of preheating cabinet and is installed with air-heater 4, the particle on conveyer belt 5 can be preheated, 1 top of the preheating cabinet
It is installed with feed hopper 6, the 2 inside ground terminal of charing case is installed with charing heater box 10, and 2 top of the charing case is solid
Dingan County is equipped with air inlet pipe 9, and one end of the air inlet pipe 9 is installed with waste gas purification apparatus 8, the waste gas purification apparatus 8 one
Side is installed with exhaust fan 7, carries out exhausting to charing case 2 by exhaust fan 7, accelerates gas flowing, and exhaust gas passes through exhaust gas
Purifier 8 purifies, and is installed with active carbon filter screen 12 inside the waste gas purification apparatus 8,3 bottom of the cooler bin is fixed
Holder is installed, the output end of the side wall of the cooler bin 3 and the corresponding conveyer belt 5 is installed with a discharge bucket 11.
Operation principle：Preheating cabinet 1 is heated in use, first opening air-heater 4, then by biologic grain through feed hopper
6 input conveyer belts 5, make biologic grain be preheated in preheating cabinet 1, the biologic grain after heating is transported to by conveyer belt 5
Case 2 is carbonized, biologic grain generates exhaust gas, tar and charcoal after the charing heating reaction of heater box 10, and exhaust fan 7 is to carbonizing case
2 inside carry out exhausting, make gas flow faster in charing case, carbonization reaction is more complete, and the exhaust gas of extraction is through waste gas purification apparatus 8
It is discharged after purification, charcoal is sent into inside cooler bin 3 by conveyer belt to carry out being transported to discharge bucket 11 after cooling down, and completes biologic grain
Charing.
Although the foregoing describe specific embodiment of the present utility model, those familiar with the art answers
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
