Description

A kind of manufacture method of artificial synthetic carbon

The present invention relates to a kind of manufacture method of charcoal, relate in particular to a kind of method of the phyteral fiber being made charcoal.

In existing charcoal processing technology, the method for phyteral fibers such as straw, wood chip, bamboo bits being made charcoal is substantially as follows: it comprise select materials, several steps such as charing, shaping, oven dry.Wherein carbonization process is finished by charring furnace, and this and traditional burning wood are got the method basically identical of charcoal, normally the plant material are placed in the stove, and it is lighted, and make the charing of plant material under airtight destructive distillation situation, and then cooling, takes out powdered carbon or charcoal piece again; The process of oven dry is finished by stoving oven, is placed in the drying baker through finished product charcoal bonding, extrusion molding, and with heater case heating, drying powdered carbon is bonding, extrusion molding, the finished product charcoal is placed in the drying baker, the electricity consumption heating, drying.In the aforesaid method, the carbonization process time is long, feed intake, discharging is very inconvenient, and can not work continuously, last stoves such as needs charing the powdered carbon cooling, take out after, just can carry out the charing of next stove, thereby efficient is low.In this carbonization process, have the plant material about 30% to be burnouted, with this as charing required light the energy.In the aforesaid method, also need auxiliary fuel heat supplieds such as electricity in the drying course, the cost of manufacture of finished product charcoal oven dry is improved greatly.

But the object of the present invention is to provide a kind of charring furnace of streamline operration to finish charing, utilize simultaneously heat that the piece material discharges manufacture method again in carbonization process the Kiln seasoned artificial synthetic carbon of finished product charcoal.

For achieving the above object, the present invention has adopted following technical scheme: the manufacture method of artificial synthetic carbon, the phyteral fiber is divided into piece material, particle, then its charing is become powdered carbon, add tackiness agent again and mix and stir, and extrusion molding, oven dry at last, after the characteristics of present method were that but particle is finished charing by the charring furnace of uninterrupted duty, the charing of the oven dry of finished product and piece material was finished by the charing stoving oven behind its extrusion molding.Particle is as follows by the process of charing in charring furnace: particle is sent into from the commentaries on classics thorax top of changing in the stove, evenly fall layer by layer with the rotating vane that changes in the thorax, the heat of heating chamber enters in the commentaries on classics thorax from the through hole that changes on the thorax wall, and light particle, particle in dropping process by charing, the particle that its heat that discharges at carbonization process will add is again subsequently lighted, and forms uninterrupted carbonization process, and powdered carbon is then discharged through discharge port.The charing of the oven dry of finished product and piece material is finished by the charing stoving oven, its process is as follows: earlier the piece material is placed in the interior stove, the finished product charcoal of need oven dry is loose shape to be placed in the drying shed, light the piece material, when interior stove Nei Wenduda is more than 600 ℃, close chimney, make chimney gas, and discharge by the smoke outlet of drying shed by drying shed.In the process that the plant material falls in changeing thorax, the temperature of changeing the thorax internal upper part is at 200 ℃～400 ℃, and the temperature at middle part is at 400 ℃～1200 ℃, and the temperature of bottom is between 200 ℃～400 ℃.

Owing to adopted technique scheme, the present invention that the charing of particle is uninterruptedly carried out, and the heat that discharges when utilizing the particle charing, its main energy sources as charring furnace is supplied with, not only improve working efficiency, and saved the energy.Simultaneously, the energy has been saved in the heat that the piece material discharges in carbonization process be used to again the to be shaped oven dry of charcoal, has reduced the manufacturing cost of artificial synthetic carbon.

Accompanying drawing 1, process flow diagram of the present invention.

The structural representation of charring furnace in accompanying drawing 2, the inventive method.

Charing structure of Stove synoptic diagram in accompanying drawing 3, the inventive method.

Below in conjunction with embodiment and accompanying drawing processing step of the present invention is further elaborated.

As shown in Figure 1: step of the present invention divided for 5 steps finished.1 is sub-material, and 2 is the charing of particle, and 3 is mixing and stirring of powdered carbon, and 4 is extrusion molding, and 5 is the charing of piece material and the oven dry of shaping charcoal.

As shown in Figure 2: earlier the plant material is divided into two kinds in particle, piece material by screen cloth, below 30 cubic centimetres is particle, and more than 30 cubic centimetres is the piece material.In the heating chamber 13 of charring furnace, put into a certain amount of block of material, and light.Subsequently particle is sent into from opening for feed 17, particle evenly falls under the effect of gravity and rotating vane 12 after entering and changeing thorax 11, commentaries on classics thorax wall 14 has through hole 15 and communicates with heating chamber 13, through hole 15 is arranged close slightly at the middle part of changeing thorax wall 14, because the effect of said structure, the temperature of changeing in the thorax 11 is followed successively by: 200 ℃～400 ℃ on top, 400 ℃～1200 ℃ at middle part, 400 ℃～200 ℃ of bottoms.Particle is falling and dehumidifying under above-mentioned temperature, smoke evacuation, charing successively under the effect of rotating vane 12 layer by layer.Subsequently, powdered carbon is discharged from discharge port 16.The inlet amount of charring furnace is the 25-50 kg/minute, determines the rotating speed of rotating vane according to the size of inlet amount, and particle is 120～320 seconds through the time of charring furnace.The powdered carbon of discharging from discharge port 16 contain the charcoal rate 60% to more than 90%.In the above-mentioned carbonization process, only need when beginning to light particle a certain amount of block of material of adding heating chamber 13 in, with this fuel that uses as point, subsequently the particle of Jia Ruing can in flame that spent particle discharged and heat, be lighted, charing.But in order to make effectively stable work of charring furnace, in process thereafter, can regularly insert some piece material slightly in heating chamber 13, the ratio of the treatment capacity of its quantity and particle was generally 6: 100.The powdered carbon of being discharged by charring furnace discharge port 16 mixes and stirs tackiness agent and powdered carbon in 1: 3 ratio after cooling, uses spiral extrusion machine extrusion molding then.

As shown in Figure 3: the finished product that is shaped is the intersecting parallels alternate tiers row pattern in the drying shed 22 of charing stoving oven, and in the stove 21, finished product is about 2: 5 with the amount ratio of piece material in the piece material being placed in again.Interior stove 21 tops have ventage 24 to communicate with chimney 23, drying shed 22.Piece material in lighting in the stove 21 makes it begin carbonization process, and the flue gas of its generation is discharged through chimney 23 by ventage 24, and the heat of its generation is transmitted to drying shed 22 by internal protecting wall 26 and plays the oven dry effect.When interior furnace temperature reaches more than 600 ℃, close chimney 23 passages, the flue gas that stove 21 produces in making, heat are by drying shed 22, and by smoke outlet 25 discharges that are located at drying shed 22 bottoms, this further provides the heat of baking needed to drying shed 22, the piece material in the simultaneously interior stove 21 have also progressively been finished charing.
