Description
Technical field
The present invention relates to a kind of fuel, relate to a kind of making method of coal derived fuel charcoal specifically.
Background technology
In recent years, increasing both at home and abroad to demand as the various fuel charcoals of heating and food and drink fuel, along with the protection increasing of country, be that the former char yield of raw material constantly descends with natural forest to the forest reserves.Machine-made charcoal is the substitute products of charcoal, and it is big to have density, the calorific value height, smokeless, tasteless, pollution-free, do not explode, advantage such as inflammable, be the Green Product of generally acknowledging in the world, current throughput even do not satisfy the market requirement.Machine-made carbon is a raw material with agricultural residuums such as sawdust, stalks, processes through operations such as super-dry, plasticizing forming, charing, cooling, packings.Plasticizing forming is to utilize the contained xylogen of biomass self cohesiveness that (140-280 ℃) produces when being heated, and adopts the screw rod extrusion forming technology, makes grain formings such as wood chip under certain pressure; Charing is the pyrolytic process of wood chip rod in kiln of moulding, finally obtains machine-made carbon, simultaneously recyclable inflammable gas and wood vinegar.
At present the problem that exists of machine-made carbon industry is, the screw rod extrusion forming technology yields poorly, the energy consumption height, the consumable accessory life-span is short, ingredient requirement is harsh; In addition, the production of machine-made carbon is difficult to obtain continuous and competent raw material supply.
Summary of the invention
Purpose of the present invention provides a kind of making method of coal derived fuel charcoal just at existing weak point in the above-mentioned prior art.
Purpose of the present invention can realize by following technique measures:
The making method of coal derived fuel charcoal of the present invention comprises the steps:
A, get bituminous coal 80 ~ 95, agricultural crop straw 0 ~ 10 and organic binder bond 4 ~ 10 by mass ratio, puddle evenly after, add an amount of moisture and mix thoroughly once more;
B, the resulting material of step a is pressed into spheroplast on shaper, afterwards the gained green-ball is dried in air naturally;
C, will put into charring furnace through natural air dried green-ball, be 400～700 ℃ in temperature, and carbonization time is to carry out charing under the condition of 90min～120min, again through cool off the coal derived fuel charcoal.
The granularity of bituminous coal described in the present invention is less than 3mm; Described agricultural crop straw is to be crushed to particle diameter less than 3mm with pulverizer behind natural air drying; Described organic binder bond is a Sodium salts humic acids; The moisture 14-16% of material before the moulding.
Shaper described in the present invention is a roller briquetting machine commonly used in the moulded coal industry.
Carbonization time described in the present invention contains the heating-up time.
Beneficial effect of the present invention is as follows:
Coal derived fuel charcoal of the present invention is main raw material with bituminous coal and agricultural crop straw, and is cheap and easy to get, adds the combustioncharacteristics that agricultural crop straw can effectively utilize biomass energy, improve fuel charcoal product.Material forming is selected roller briquetting machine for use, and the output height, energy consumption is low, equipment attrition is little.Carbonization temperature is low, the time is short, energy consumption is little.Gained coal derived fuel charcoal product physical strength height, ultimate compression strength〉25kg/; Fixed carbon〉75%; Fugitive constituent〉10%; Ash＜10%; Calorific value〉7000 kilocalories/Kg; Easily igniting, anti-burning, burning are complete, no smoke, no Mars flue dust, stove table temperature height.
