Abstract
The invention discloses a method for preparing coal-based fuel carbon, which comprises the following steps of: a, taking the following components in percentage by mass: 80 to 95 percent of bituminous coal, 0 to 10 percent of crop straw and 4 to 10 percent of organic binder, uniformly mixing, and adding a proper amount of water for uniform mixing; b, pressing materials obtained in the step a into spheroids on a molding machine, and naturally airing the obtained green pellets; and c, putting the naturally aired green pellets into a carbonization furnace, carbonizing at the temperature of between 400 and 700 DEG C for 980 to 120 minutes, and cooling to prepare the coal-based fuel carbon. The coal-based fuel carbon has the advantages of cheap and readily available raw materials, low cost, effective utilization of biomass energy, the compressive strength of the prepared fuel carbon product of 25kg/piece, 75 percent of fixed carbon, 10 percent of volatile matter, 10 percent of ash content, 6,500 kilocalorie/kg of heat value, 0.4 percent of sulfur content, easy ignition, fire resistance, complete combustion, no smoke, no spark or smoke dust, high furnace surface temperature, high stability, and no collapse or break in the combustion process.
Description
Technical field
The present invention relates to a kind of fuel, relate to specifically a kind of making method of coal-based fuel carbon.
Background technology
In recent years, increasing to the demand as the various fuel carbons of heating and food and drink fuel both at home and abroad, along with the protection increasing of country to the forest reserves, the former char yield take natural forest as raw material constantly descends.Machine-made charcoal is the substitute products of charcoal, has density large, and calorific value is high, smokeless, tasteless, pollution-free, do not explode, the advantage such as inflammable, be the Green Product of generally acknowledging in the world, current throughput even can not meet the market requirement.Machine-made carbon is take forest and agricultural biomass such as sawdust, stalks as raw material, 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 extruding forming technique, makes the 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.
The problem of machine-made carbon industry existence at present is that the screw extruding forming technique yields poorly, energy consumption is high, 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 sufficient raw material supply.
Summary of the invention
Purpose of the present invention provides a kind of making method of coal-based fuel carbon just for existing weak point in above-mentioned prior art.
Purpose of the present invention can realize by following technique measures:
The making method of coal-based fuel carbon of the present invention comprises the steps:
A, get bituminous coal 80 ~ 95, agricultural crop straw 0 ~ 10 and organic binder bond 4 ~ 10 in mass ratio, after puddling evenly, add appropriate moisture again to mix thoroughly;
B, the resulting material of step a is pressed into spheroplast on forming machine, afterwards the gained green-ball is dried in air naturally;
C, will put into charring furnace through the green-ball that naturally dries, be 400～700 ℃ in temperature, and carbonization time is to carry out charing under the condition of 90min～120min, then through cooling coal-based fuel carbon.
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 after natural air drying; Described organic binder bond is Sodium salts humic acids; The moisture 14-16% of material before moulding.
Forming machine described in the present invention is roller briquetting machine commonly used in 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-based fuel carbon of the present invention is take bituminous coal and agricultural crop straw as main raw material, and is cheap and easy to get, adds the combustioncharacteristics that agricultural crop straw can effectively utilize biomass energy, improve the fuel carbon product.Material forming is selected roller briquetting machine, and output is high, energy consumption is low, equipment attrition is little.Carbonization temperature is low, the time is short, energy consumption is little.Gained coal-based fuel carbon product physical strength is high, ultimate compression strength〉25kg/; Fixed carbon〉75%; Fugitive constituent〉10%; Ash＜10%; Calorific value〉7000 kilocalories/Kg; Easily igniting, anti-burning, burning are complete, smoke smell free, high without Mars flue dust, stove table temperature.
