Embodiment 1

[0031] A kind of preparation technology of biomass power charcoal, its method is:

[0032] 1) Take the biomass, that is, the straw, collect it, dry it in the air until the moisture content is 30%, and then pulverize it;

[0033] 2) The crushed straw is sent to the carbonization pool, under the isolation of air, at the ignition temperature (that is, after the straw is ignited, immediately lay another layer of straw on it, and so on layer by layer) Carry out low-temperature carbonization for 6 hours, and use the carbonization pool to remove the tar therein;

[0034] 3) Biomass carbon powder and inorganic binders generated after carbonization, such as: bentonite, kaolin, clay, white mud, river mud, etc., or cement, or water glass, raw (cooked) ash, calcium carbide mud, phosphate, Sulphate etc. and admixture argillaceous coal gangue are by weight: 70 parts of biomass charcoal powder, 15 parts of inorganic binders, 15 parts of argillaceous coal gangue fully stir and mix in proport...

Embodiment 2

[0039] A kind of preparation technology of biomass power charcoal, its method is:

[0040] 1) Take the biomass, that is grass, and dry it after collecting until the water content is 30%, and then pulverize;

[0041] 2) The pulverized material is sent to the carbonization tank, and under the isolation of air, low-temperature carbonization is carried out at the ignition temperature for 7 hours, and the tar therein is removed;

[0042] 3) Biomass carbon powder and organic binders generated after carbonization, such as: coal tar pitch, coal tar or PVA, FAA, PA, PE or starch or vegetable oil residue or animal glue; or pulp waste liquid or lignocellulose Equally and admixing sandy coal gangue in parts by weight: 80 parts of biomass charcoal powder, 10 parts of organic binder, fully stirring and mixing in proportion of 10 parts of admixing sandy coal gangue;

[0043] 4) The stirred material is sent to the molding machine to be shaped into granules to make biomass charcoal for power;...

Embodiment 3

[0047] A kind of preparation technology of biomass power charcoal, its method is:

[0048] 1) Take biomass, that is, all kinds of wood, collect and air-dry until the water content is 30% and then pulverize;

[0049] 2) The pulverized material is sent to the carbonization tank, and under the isolation of air, low-temperature carbonization is carried out at the ignition temperature for 7.5 hours, and the tar therein is removed;

[0050] 3) Biomass charcoal powder and composite binder generated after carbonization, such as: coal tar and pulp composite, etc., and then mixed with fine sand in parts by weight: 75 parts of biomass charcoal powder, 20 parts of composite binder, and The ratio of 15 parts of fine sand is fully stirred and mixed;

[0051] 4) The stirred material is sent to a molding machine to be shaped into a block to make biomass charcoal for power;

[0052] 5) The finished product after airing and drying.

[0053] The finished biomass power charcoal is directly sen...

Abstract

The present invention discloses one kind of biomass charcoal and its production process and application in generating electricity, and relates to stalk utilizing technology. The biomass charcoal producing process includes the following steps: 1. drying stalks in the sun and crushing; 2. charring in the charring tank and eliminating tar; 3. mixing biomass charcoal in 70-80 weigh portions, adhesivein 10-15 weigh portions and additive in 10-15 weigh portions; 4. forming the mixture in a forming machine; and 5. drying the formed biomass charcoal.

Description

technical field [0001] The invention relates to a power generation technology utilizing crop stalks, in particular to a preparation process of biomass power charcoal and its application in power generation. Background technique [0002] The electric power industry is an important part of the energy industry, providing power support for economic development, and thermal power generation using coal for power is currently the most important method of power generation, but my country's existing thermal power generation units have high coal consumption, low efficiency, serious pollution. [0003] Since coal is a non-renewable energy and it will produce a large amount of harmful gas and pollute the environment when it is burned, people are looking for a renewable energy to replace the use of coal to ensure sustainable economic development, and use crop straw to generate electricity It is an emerging power generation technology. [0004] At present, there are three modes of domest...
