Description
Technical field
The present invention relates to a kind of preparation method of high-performance compounding machine charcoal processing, belongs to technical field of resource comprehensive utilization.
Background technology
For a long time, charcoal is widely used as always life fuel, and charcoal is that timber burns under conditions of anoxic
Or pyrolysis and produce, production charcoal needs to consume the substantial amounts of forest reserves, heavy damage ecological environment, China's forest cover
Less than the 10% of territory, the formation of forest needs certain growth cycle, substantial amounts of deforestation not to meet protecting ecology ring to area
Border, the requirement for creating low charcoal society, developing a circular economy；The production method of conventional charcoal is that timber is put among stove to be pyrolyzed
Carry out earth kiln charcoal processing technique have the shortcomings that poor sealing, long the production cycle, yield poorly, the cigarette in high cost, and pyrolytic process
Gas is directly discharged, and not only waste of resource also creates environmental pollution, in recent years, with the raising of national requirements for environmental protection, earth kiln system
It will be trend of the times that charcoal is eliminated；
Agricultural-forestry biomass raw material is typical regenerative resource, and it has a wide material sources, rich reserves, and it is excellent that growth cycle is short etc.
Point.The biomass total amount of annual production is about 1400 ~ 180,000,000,000 tons on the earth, and China's stalk discarded every year is up to more than 6,000,000,000
Ton, resource has a high potential, and agricultural-forestry biomass raw material is pyrolyzed the pore space structure prosperity of gained biomass carbon, is readily burned.But agriculture
Woods biomass resource there is also its limitation, be mainly shown as：Distribution is not concentrated, not easily collecting etc., therefore agricultural are used alone
Biomass prepare machine-made carbon for raw material, consider much meet need of the daily productive life to carbonaceous fuel from yield angle
Ask；China's lignite resource enriches, and cheap, but brown coal volatile ingredient height (>40%), fixed carbon content is low, pore space structure not
Prosperity, the machine-made carbon combustion efficiency that brown coal preparation is used alone is undesirable, and these shortcomings limit the application of brown coal, are with brown coal
Raw material, low temperature distillation in employing carries out charing process to brown coal, sloughs most of moisture therein and volatile matter, obtain performance compared with
Good lignite semi-coke charcoal, and it is mixed with biomass carbon, its range of application can be expanded.
Based on background above, this paper presents one kind both to have overcome biomass carbon yield little, brown coal fixed carbon is solved again
Content is low, compounding machine charcoal processing preparation method the problems such as pore structure is undeveloped.It is contemplated that making full use of reproducible agriculture
Woods biomass resource and cheap, rich reserves brown coal, first with pyrolysis（Destructive distillation）Technology is to agricultural-forestry biomass raw material
It is processed, the flue gas in pyrolytic process is fully used, and the byproduct biomass carbon produced by being pyrolyzed（With comparing
It is little）With the brown coal of reserves very abundant（Proportioning is larger）Second step charing is carried out after mixing, flue gas volatilization in carbonization process is removed,
The porosity of compounding machine charcoal processing is increased, and flue gas is entered and absorbed in pond, the moisture for absorbing flue gas is used again by circulation
Close machine-made carbon dispensing link.Compounding machine charcoal processing prepared by the present invention not only solves the limitation of both biomass carbon and brown coal,
And resource is recycled, meet the requirement of energy-conserving and environment-protective, Green Development.
The content of the invention
The problem existed for above-mentioned prior art and deficiency, the present invention provides a kind of preparation of high-performance compounding machine charcoal processing
Method.The preparation process is with abundance, cheap, the renewable and biomass that are easy to crush and cheap brown
Coal is carbon source, with the compounding machine charcoal processing for mass producing high low price, high income, calorific value, porosity height, be extensively received by the market
Potential.The present invention is achieved through the following technical solutions.
A kind of preparation method of high-performance compounding machine charcoal processing, it is comprised the following steps that：
（1）First biomass material that moisture content is less than 5%, brown coal are crushed to into respectively particle of the granularity less than 1cm；
（2）By step（1）The biomass raw material particle for obtaining pyrolysis in the case where temperature is for 400 DEG C～900 DEG C obtains charcoal, by heat
The biomass gas produced in solution preocess are used as combustion gas after further processing；
（3）By mass percent be 10～40% the step of（2）The charcoal that obtains, mass percent are 40～70% steps（1）
The brown coal that obtain, mass percent be 1～10% binding agent, mass percent 1～10% be combustion adjuvant, mass percent be 5～
14% water is well mixed and obtains mixed material, and mixed material is pressed into into the carbon rod with centre bore；
（4）By step（3）The carbon rod with centre bore for obtaining is warming up to 400～700 with the heating rate of 30～200 DEG C/min
DEG C charing 1～12h, compounding machine charcoal processing is obtained after cooling.
The step（1）Middle biomass material is walnut shell, pine nut shell, cocoanut shell, corncob, bagasse, furfural dregs, coffee
One or several arbitrary proportion mixtures in coffee shell, peanut shell.
The step（3）Middle binding agent preparation method is：By the mud coal containing more than 30wt% humic acids, brown coal or weathered coal
Particle diameter is crushed to less than 1mm, is 1～10 according to liquid-solid ratio:1ml/g is added to the NaOH solution that percent concentration is 5～30%
In, stir 20～40min in the case where temperature is for 80～120 DEG C and prepare binding agent.
The step（3）The combustion adjuvant for obtaining be 50～80wt% manganese dioxide, 15～30wt% alundum (Al2O3)s and 5～
20wt% calcium carbonate mixtures.
The step（4）The pyrolysis smoke that carbonization process is produced will be incorporated in cistern by pipeline and will be only absorbed by the water, and be stored
Sewage in pond will be recycling in step（3）The middle water as mixed material.
The invention has the beneficial effects as follows：Fixed carbon content >=80% of the machine-made carbon, ash content≤5%, calorific value >=35MJ/Kg,
Minimum temperature is more than or equal to 420 DEG C during burning；Biomass material used and brown coal are cheap in the machine-made carbon, deliming effect
Good, porosity is high, and two-step carbonization is adopted in the preparation process of the machine charcoal processing, and first step carbonization process is the pyrolysis of biomass material
（Destructive distillation）Charcoal-gas coproduction, pyrolysis smoke and byproduct biomass carbon are fully used；Second step is biomass carbon（Match somebody with somebody
It is smaller）, brown coal（Proportioning is larger）Deng mixture charing, in improve the fixed carbon content of brown coal, and volatile matter removal process
