Abstract
A kind of production method of utilizing straw to produce flake porous charcoal is characterized in: comprise select materials, shred, pulverizing, moulding, loading of kiln, intensification, charing, cooling, packaging process, perhaps first charing aftershaping.Its technology comprise select materials, moulding, loading of kiln, intensification, charing, cooling, pulverizing, batching, formed package operation.60 tons of extrusion equipment in-mold moldings are adopted in moulding, and charcoal is block-shaped for many ribs or cylindrical, end face have at least 3 axial openings, even fragment is axially arranged and be linked to be rod or globulate, olive shape.This method production cost is low, but continuous production, and charcoal piece hardness is controlled, can light with match.
Description
The present invention relates to a kind of production method of machine-made carbon, is a kind of production method of utilizing the plant straw to produce flake porous charcoal.
At present, the method for utilizing furfural dregs, vinasse and each kind of plant straw to produce charcoal mainly contains two kinds: a kind of be with the charcoal machine extrude carbon rod, this method power consumption is too high, the cost height, technology does not pass a test, and does not have practical value; Two kinds be to be extruded into excellent after drying destructive distillation (charing) earlier, this method little power consumption, and cost is low, but the moulding component wear is excessive, can not guarantee ordinary production, and carbon rod hardness is higher, with match point not.
The purpose of this invention is to provide a kind of method of utilizing the plant straw to produce flake porous charcoal, to solve the above-mentioned shortcoming of current mechanism charcoal production method, reducing cost ensures safety in production, and turns waste into wealth.
The object of the present invention is achieved like this: the method for utilizing the plant straw to produce flake porous charcoal has two kinds: the one, charing after the first moulding, its production technique comprise select materials, shred, pulverizing, moulding, loading of kiln, intensification, charing, cooling, packaging process form; Two kinds is pulverizing, moulding after the first charing, its production technique comprises: select materials, moulding, loading of kiln, intensification, charing, cooling, pulverizing, batching, moulding, packaging process form, 60 tons of extrusion equipments are adopted in moulding, at in-mold molding, kiln is selected many courages annular kiln for use, and carbonization temperature is controlled at 200-250 ℃.
Elder generation's charing aftershaping proportioning raw materials: (weight %)
Powdered carbon 85-90%, water 6-12%, tackiness agent 3-9%
Below in conjunction with embodiment technology is further specified:
Its technological process of production of charing is after example 1, the first moulding:
Select materials-shred-pulverize-moulding-loading of kiln-intensification-charing-cooling-packing.
Specification:
1) select materials: select dried plant straw for use, water content is less than 12%, removes impurity such as brick and tile, lump of earth.
2) chopping: select for use hay cutter to cut into chunks, its length is as the criterion to pulverize the function wedging.
3) pulverize: adopt pulverizer that straw is pulverized and be powdery, longest fiber is not more than 15mm.
4) moulding: adopt 60 tons of extrusion equipments, as honeycomb briquette upper and lower mould moulding, by the counterdie tube extrude flake porous rod.It is shaped as cylindrical or multi-edge column-shaped, and end face has at least 3 axial openings, and uniform fragment is axially arranged, but is linked to be bar-shapedly, firmly fragment can be separated, if more mold exchange also can be pressed into sphere or olive shape, forming pressure is the 35-40 ton, is 3.43-3.92MPa.
5) loading of kiln: adopt many courages annular kiln continuous production, courage also can be selected drying and carbonization dual-purpose stove batch production for use for the encloses container of band hermatic door and vent valve.
6) heat up: adopt electrically heated, also can select fuel heating such as combustible gas or oil, straw for use, stop heating when being raised to 200 ℃ and enter char zone.
7) charing: temperature is controlled at 200-250 ℃ of insulation 8 hours in char zone, enters the cooling zone then and slowly cools off.
8) cooling: adopt naturally cooling or blowing to force cooling.
9) packing: can adopt box or bag type package
Example 2: the technical process of first charing aftershaping is: select materials-moulding-loading of kiln-intensification-charing-cooling-pulverizing-batching-moulding-packing.
Select materials in the operation, loading of kiln, intensification, charing, cooling, packaging process be with example 1, different is:
1) moulding: straw shaped employing packing machine is pressed into bulk, or manually straw is pressed in the kiln courage; 60 tons of extrusion equipments are adopted in the powdered carbon moulding, and at in-mold molding, that carbon rod is shaped as is cylindrical, multi-edge column-shaped, end face have at least 3 axial openings uniform, uniform fragment is axially arranged but is linked to be bar-shapedly, firmly fragment separately also can be able to be pressed into sphere, olive shape.Forming pressure is the 35-40 ton, is 3.43-3.92MPa.
2) pulverize: adopt pulverizer.
3) batching: powdered carbon 90%, water 4%, tackiness agent (wood tar oil or paper pulp) 6%, with stirrer or manually mix.
This invention compared with prior art has the following advantages: 1) the high 3.57MJ/ kilogram of calorific value (8500 kilocalorie/kilogram); 2) inflammable, can light with match; 3) cost is low, can produce continuously; 4) the charcoal piece adopts mould molding, and shape is changeable, can produce flake porous rod, and is if more mold exchange also can be produced sphere, olive shape rod, easy to use.
