Abstract
The invention discloses a preparation method of bio-coal. The method adopts the raw materials of coal, dry crop straw, clay and hydrated lime with a weight ratio of 10 to 7-9 to 1-3 to 0.4-0.6. The bio-coal is prepared through the steps of crushing, blending, molding and air drying. According to the invention, the raw materials are uniformly mixed with a mixer; the mixture is granulated with a high-pressure granulator, wherein a granulation pressure reaches 2000-4000 kg/cm<2>; and the obtained bio-coal granules are air dried. The method adopts a high-pressure bonding process. Various plant straws and the coal are mixed and extruded. The bio-coal has an advantage of full combustion. With the bio-coal, a large amount of crop straws can be consumed, such that the environment can be protected, and coal resource is saved. The prepared bio-coal has a good combustion effect, and is convenient to use.
Description
Technical field
The present invention relates to a kind of preparation method of biofuel, be specifically related to a kind of preparation method of biological coal.
Background technology
Coal is Nonrenewable resources, and along with the continuous exploitation of coal, coal reserves reduces day by day.Biological coal is the solid fuel be combined into according to a certain percentage with biomasss such as coal and vegetation stalks, is a kind of New-type fuel of Substitute coal, also becomes biological coal briquette, is particularly suitable for the fuel that Rural areas uses.Be beneficial to environment protection due to biological coal and fully digest agricultural crop straw and make full use of low-grade coal resources, produce biological coal technique simply, less investment is the good investment project in rural area simultaneously.Therefore the preparation method researching and developing new biological coal has great importance.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provide a kind of newly, workable, the preparation method of the biological coal that combustion efficacy is good.
Technical problem to be solved by this invention is realized by following technical scheme.The present invention is a kind of preparation method of biological coal, is characterized in: raw materials used for coal, dry agricultural crop straw, clay and slaked lime, through pulverizing, batch mixing, shaping, dry and form; The weight ratio of feed coal, agricultural crop straw, clay and slaked lime is 10:7-9:1-3:0.4-0.6; Raw material mixer mixes, and carries out granulation with high pressure tablets press, and granulation pressure reaches 2000-4000 kg/cm, is finally dried by biological coal particle and get final product.
In the preparation method of a kind of biological coal of the present invention: the weight ratio of feed coal, agricultural crop straw, clay and slaked lime is preferably 10:8:2:0.5.Granulation pressure preferably reaches 3000 kg/cm.
Compared with prior art, the present invention adopts high pressure bonding process, by various straw and coal extrusion shaping; not only sufficient combustion, but also agricultural crop straw can be digested in a large number, protection of the environment; save coal resources, obtained biological coal combustion efficacy is good, easy to use.
