Matter charcoal 3 class product.Wherein gas-phase product (combustible gas) is used for generating electricity, supplies or hot combustion gas etc.；Solid product (biomass
Charcoal) high added value activated carbon (shell class) and industrial reducing agent and civilian can be prepared respectively according to the difference of biomass material
Charcoal for roasting (wooden class), charcoal base organic-inorganic Chemical Mixed Fertilizer (stalk raw materials)；Liquid product (biomass extract) prepares liquid
Fertilizer.At present, solid product (wooden class)-Linesless charcoal produces industrial reduction agent and quick burning charcoal does not have because product index is unstable yet
Obtain industrialization.Product liquid-wood tar recycling is a difficult problem being currently needed for solving.Wood tar is wood chip gasification
One of Poly-generation production technology fluid product, is a kind of thick organic mixture of pitchy, and research shows wood tar
In containing 40% about phenolic compound, comprising: the phenol derivatives such as phenol, xylenol, catechol, guaiacol.Volatilization
A large amount of presence of property aldehydes matter show that biomass coke tar has certain hazardness to environment, and biomass coke tar is any simultaneously
Throw aside, will also result in the wasting of resources.
Content of the invention:
Proposed by the present invention is a kind of wood tar base adhesive, the gasification forming charcoal made of charcoal, and its purpose is intended to will be many for gasification
The intractable side-product of coproduction-wood tar substitutes part phenol wood tar base adhesive in addition recycling, minimizing molding
The usage amount of charcoal adhesive phenol, reduces production cost, meanwhile, prepares solid molding fuel charcoal with gasification charcoal, high heating value Linesless charcoal
There is some strength, burning is smokeless, tasteless and meets national standard and the market demand.Present invention process is easy, easy to process, with
When can higher value application wood tar and gasification charcoal.
The technology of the present invention solution: the forming charcoal made with wood tar base adhesive, gasification charcoal, obtained by wood chip gasification
Linesless charcoal pulverize after, wood tar base adhesive, high heating value Linesless charcoal be blended by a certain percentage, be re-fed into being squeezed into in former
Type charcoal is it is contemplated that its forming charcoal meets charcoal industry standard, Charcoal Weight content 80%-90%, wood tar base adhesive weight
Amount content 5%-10%, high heating value Linesless charcoal (more than caloric value 33mj/ kg) 5%-10%(is adjusted according to gasification charcoal carbon content height
Whole).
Wood tar therein is with wood wastes as raw material with gasification charcoal, in finite quantity oxygen supply (0.8m3Air/1kg is former
Material) under the conditions of, with air as gasifying agent, obtain solid by-product and product liquid in 600-700 DEG C of gasification.
Wood tar base adhesive therein is to replace phenol (to substitute with wood chip gasification gained wood tar (phenols content 40%)
Amount 12%) react with formaldehyde, then with polyvinyl formal, its modified (solid content: 40%, viscosity: 120mpa.s) is obtained.
Advantages of the present invention:
1) primary raw material of the present invention is Gasification Polygeneration System side-product Linesless charcoal, wood tar, not only solves wood tar recycling
Problem, and by Linesless charcoal higher value application, extend industrial chain.
2) intractable for Gasification Polygeneration System side-product-wood tar is substituted part phenol wood tar base adhesive to be provided
Sourceization utilizes, and reduces the usage amount of forming charcoal adhesive phenol, reduces production cost, meanwhile, with gasification charcoal, high heating value Linesless charcoal system
Standby solid molding fuel charcoal has some strength, burning is smokeless, tasteless and meets national standard and the market demand.Present invention process
Easy, easy to process, simultaneously can higher value application wood tar and gasification charcoal.
Brief description
Accompanying drawing 1 is forming charcoal production technological process.
Specific embodiment
Below by specific example, the present invention is further described.
In example, Linesless charcoal and wood tar derive from the wood chip biomass gasification boiler Poly-generation project of the prosperous wood industry of Jiashan of Zhejiang Xinhua: former
Material derives from wood industry processing waste, leftover pieces etc., granular size 4cm, sends into biomass multi-production gasification installation, in 600-
At 700 DEG C, gasification produces combustible gas, biomass carbon, bio liquid.(its waste log and gasification charcoal Industrial Analysis such as table 1 below)
Table 1 wooden waste, the Industrial Analysis (unit is wt.%) of gasification charcoal
Take 20kg gasification charcoal to pulverize through pulverizer, cross 20 mesh sieves standby；
30g wood tar is taken to react by 1:1.1 formaldehyde with 250g phenol, more modified to it with polyvinyl formal and starch
It is standby that (solid content: 40%, viscosity: 120mpa.s) is obtained 500g wood tar base adhesive；
Take 200g high heating value Linesless charcoal to pulverize through pulverizer, cross 20 mesh sieves standby；
Take phenol glue 500g standby.
Market purchase mechanism carbon rod 500g, standby.
With wood tar base adhesive, gasification charcoal forming charcoal: the gasification charcoal that processed 10kg and the high heating value of 200g are wooden
Charcoal stirs, and after then taking 500g wood tar base adhesive and 500g water to stir, is added into gasifying in charcoal, simultaneously plus
The water entering 2.5kg stirs, and sends into forming machine molding system rod afterwards,
Finally send into oven for drying to moisture content 5%.
Phenol glue forming charcoal: after taking 500g phenol glue and 500g water to stir, be added into the gas that 10kg was processed
Change in charcoal, the water being simultaneously introduced 2.5kg stirs, send into forming machine molding system rod afterwards, finally send into oven for drying extremely aqueous
Rate 5%.
Do not compare because amylan forming charcoal intensity is relatively low.
Mechanism molding: market is buied
3) three kinds of charcoal physicochemical properties are shown in Table 2
Table 2 solid fuel physicochemical property
Wood tar base adhesive, the every physical and chemical index of gasification charcoal forming charcoal be close to machine-made carbon as seen from the above table, better than phenolic aldehyde
Gum forming charcoal.
Combustion index is shown in Table 3
Table 3 forming charcoal integrated combustion property index
| Ignition temperature DEG C | Maximum combustion speed (dw/dt)max(%/DEG C) | Average combustion rate (dw/dt)mean(%/DEG C) | Burn-out temperature DEG C | Comprehensive combustion index | |
| Charcoal for roasting | 400 | 0.412 | 0.0481 | 657 | 1.8852e-10 |
| Phenol glue forming charcoal | 325 | 0.461 | 0.0913 | 540 | 7.37923e-10 |
| Forming charcoal of the present invention | 360 | 0.400 | 0.05200 | 571 | 1.7504e-10 |
As seen from the above table wood tar base adhesive, gasification each combustion index of charcoal forming charcoal close to machine-made carbon, better than phenol glue
Forming charcoal.
Contrast mechanism's charcoal industry standard wood tar base adhesive, gasification charcoal forming charcoal are primes.
