Description
Technical field
The present invention relates to machine-made carbon preparing technical field, and in particular to a kind of preparation side of high heating value fragrant machine-made carbon
Method.
Background technology
Machine-made carbon, also known as artificial carbon, regenerated carbon, smokeless clean charcoal, be with woody debris' extrusion process into carbonaceous it is bar-shaped
Thing.Rod carbon feedstock wide material sources, rice husk, peanut shell, boll hull, corncob, cornstalk, kaoliang stalk etc. all can be used as raw material production rod
Charcoal, it is optimal using sawdust, wood shavings, bamboo scraps.With wood chip（Sawdust）For primary raw material, branch, rice husk, bamboo scraps, peanut skin, sunflower seeds
It can also be used after shell, furfural dregs, schlempe, bagasse, corncob, cocoanut shell, coffee shell and southern and northern crops stalk crushing,
But matching method need to be groped to adjust.Drying stove is dried into the appropriate standard raw material of humidity, and forming machine is entered after cooling（System
Rod machine）, then through high temperature, high pressure plasticizing aftershaping is firewood rod（Semi-finished product）, through retort（The form of carbide furnace is varied, and one
As be brick clay kiln）Charing finished product charcoal.Machine-made carbon density is big, and calorific value is high, it is smokeless, tasteless, pollution-free, do not explode,
It is inflammable, it is green product generally acknowledged in the world.
Charcoal has following difference compared with charcoal：1st, it is environmentally friendly：Do not fall trees, produced using bamboo and wood products's waste material,
Turn waste into wealth.And producing common charcoal will fall trees, ecological environment is destroyed；2nd, high energy：Fixed carbon content 80% or so, calorific value
7500-8000kcal/kg, and the fixation carbon content of charcoal is low, calorific value 6500kcal/kg or so；3rd, sanitation and hygiene：Smokelessly without charcoal
During head, burning no-spark, burning residual ash fall naturally do not float up, after the burning of ash 3% or 6% or so it is residual it is grey less, it is inflammable；4、
Regular shape, it is rational in infrastructure, it is easy to use, there are uniform length and size, hollow or solid construction, beneficial to burning and use；5、
Water content is low：Within 5%, common charcoal water content is big；6th, without chemical substance, nontoxic free from extraneous odour, pollution-free, burning time
The advantages that long.But the calorific value of existing machine-made carbon and burning time are often not fully up to expectations.In addition, these machine-made carbons are being made
During work, often not easy-formation, machine-made carbon charcoal rate is very low, density and mechanical strength are also not high enough.Some machine-made carbons exist
Waste gas and pernicious gas are generated when burning insufficient, welding also endangers health.
Machine-made carbon is using wide, and for raw material using also relatively wide, demand is quite big.Therefore, developing one kind can solve
The machine-made carbon of certainly above-mentioned performance issue is highly desirable.
The content of the invention
The technical problems to be solved by the invention：For current common machine-made carbon in combustion, combustion heat value is not high
And unpleasant taste is easily produced, cause the defects of machine-made carbon is intolerant to burning, there is provided a kind of high heating value fragrant machine-made carbon
Preparation method.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
A kind of preparation method of high heating value fragrant machine-made carbon, it is characterised in that specifically preparation process is：
（1）Pine sawdust and cedar sawdust are mixed to be placed in pulverizer and crushed, sieving obtains granular mixing wood chip, places into soft
Change and soften in device, obtain self-control softening wood chip, it is standby；
（2）By pecan is fluffy, Chinese chestnut fruit is fluffy, rice husk, peanut skin and bagasse are mixed to be placed in pulverizer and crushed, it is screened to
It is granular, place into demineralizer and soften, obtain self-control softening discarded object, it is standby；
（3）Weigh 10~12g lotus leaves and the mixing of 16~18g lavenders be placed in 4~6g peach gums, 6~10mL Yoghourts and 10~
In the fermentation tank of 12mL deionized waters, it is sealed by fermentation, filtering, removes fermentation filter residue, obtains making filtrate by oneself；
（4）Count in parts by weight, weigh self-control softening wood chip, self-control softening discarded object, self-control filtrate and lignite respectively and be put into baking
Dried in dry machine, discharging, obtain mixture, then mix to be placed in screw type shaping machine with calcium carbonate powder and alumina powder and press
Type is made, discharges, obtains moulding stick；
（5）After above-mentioned moulding stick is loaded into block form steelframe car, place into brick clay kiln, first carbonize, continue to refine, natural cooling
To room temperature, discharging, you can high heating value fragrant machine-made carbon is made.
Step（1）Described pine sawdust and the mass ratio of cedar sawdust are 1：1, grinding time is 10~12min, grain diameter
For 1~3mm, softening temperature is 400~500 DEG C, and the softening time is 6~8min.
Step（2）The quality such as described pecan is fluffy, Chinese chestnut fruit is fluffy, rice husk, peanut skin and bagasse are, grinding time
For 8~10min, grain diameter is 0.5~0.7mm, and softening temperature is 400~500 DEG C, and the softening time is 7~9min.
Step（3）Described fermentation temperature is 35~45 DEG C, and fermentation time is 7~9 days.
Step（4）Described meter in parts by weight, it is soft that 30~40 parts of self-control softening wood chips, 12~20 parts of self-controls are weighed respectively
Change discarded object, 6~8 parts of self-control filtrates, 8~10 parts of lignite, 4~6 parts of calcium carbonate powders and 3~5 parts of alumina powders, dry temperature
Spend for 130~140 DEG C, drying time is 20~30min, and the moisture content of mixture is 2%~3%, and forming temperature is 320~420
DEG C, briquetting pressure be 8~10MPa, molding time is 1~2h, and the external diameter of moulding stick is 40~50mm, and the internal orifice dimension of moulding stick is
10~16mm.
Step（5）Described carbonization temperature is 260~300 DEG C, and carbonization time is 3~5 days, and it is 690 to continue refining temperature
~700 DEG C, refining time is 4~6h.
Compared with other method, advantageous effects are the present invention：
（1）Of the invention uses the fluffy discarded object of each seed pod in agricultural production, is made filtrate by oneself and helped using pine sawdust and cedar sawdust as base material
The making that agent etc. carries out machine-made carbon as filler is fired, wherein constantly increasing containing carbochain, carbon elements are continuously increased, to a certain degree
On reduce the calorific value for keeping and enhancing machine-made carbon on the basis of wood chip dosage, reduce the use of timber resources, also will
Discarded object in agricultural production is sufficiently used, and reduces the destruction to environment, and carbonaceous material is continuously increased, greatly
Ground has expanded the source of mechanism carbon feedstock, so as to improve the calorific value of machine-made carbon, because Chinese chestnut fruit is fluffy and pecan is fluffy to mechanism
Filling inside charcoal, and rice husk, peanut skin and bagasse are also effectively filled, and the phosphorus content for being advantageous to machine-made carbon improves, also right
The calorific value of wood chip plays humidification, again so as to improving the calorific value of machine-made carbon；
（2）The present invention reasonably matches the content of cellulose in raw material and lignin, it is ensured that and machine-made carbon has certain hardness, then
Lignite, combustion adjuvant and peach gum are added, at high temperature under high pressure, machine-made carbon inside is effectively filled, makes top layer moisture evaporation, with
Reduce the time of heat confession and the consumption of fuel, it is ensured that machine-made carbon there are enough calorific values, continuously adds by lotus leaf and lavender processing
Into filtrate of the self-control with fragrant, it is dispersed in mixing inside machine-made carbon and surface, promotes machine-made carbon firing
The smell of delicate fragrant is given out during burning, is with a wide range of applications.
