Technical Field

the invention relates to a wood chip pellet fuel, in particular to a wood chip pellet fuel and a preparation method thereof.

Background

with the continuous development of global economy, the demand of human beings on energy is continuously increased, while the energy resources such as petroleum, natural gas, coal and the like are continuously reduced, and the development of biomass renewable energy sources is a hot spot concerned by all circles. China is a large country of solid biomass energy, biomass fuels such as various crop wastes, forest wastes and the like are extremely abundant, but the biomass fuels cannot be effectively utilized for a long time, and generally, the biomass fuels are incinerated or buried or decomposed and fermented to prepare chemical fertilizers, so that the environment is polluted, the waste resources are easily wasted, the recycling rate is not high, and high-value products with large market demand are difficult to prepare. Therefore, the problems of difficult resource recycling, low recycling value and low recycling rate of the crop and forest waste exist at present.

Disclosure of Invention

The invention aims to provide a wood chip pellet fuel and a preparation method thereof. The method has the advantages of fully recycling the crops and the forest waste, improving the recovery rate of the crops and the forest waste, and remarkably improving the recycling value of the crops and the forest waste, along with simple and practical process.

the technical scheme of the invention is as follows: the sawdust pellet fuel is prepared from the following raw materials in parts by weight: 80-100 parts of China fir sawdust, 20-40 parts of rice hull, 10-15 parts of dry cow dung, 1-5 parts of corncob, 1-5 parts of combustion improver and 1-3 parts of adhesive.

In the above wood chip pellet fuel, the wood chip pellet fuel is prepared from the following raw materials in parts by weight: 85-95 parts of China fir sawdust, 25-35 parts of rice hull, 12-14 parts of dry cow dung, 2-4 parts of corncob, 2-4 parts of combustion improver and 1-3 parts of adhesive.

In the above wood chip pellet fuel, the wood chip pellet fuel is prepared from the following raw materials in parts by weight: 90 parts of China fir sawdust, 30 parts of rice hull, 13 parts of dry cow dung, 3 parts of corncob, 3 parts of combustion improver and 2 parts of adhesive.

the preparation method of the wood chip pellet fuel comprises the following steps;

a, respectively adding rice hulls, dried cow dung and corncobs into a grinder, and grinding into particles with the diameter of 2 ~ 4 mm;

b: uniformly mixing the rice hulls, the dry cow dung, the corncob particles and the cedar wood chips to obtain mixed particles;

c: drying the mixed particles by a dryer until the water content is 3-8%;

d: adding a combustion improver and an adhesive into the dried mixed particles, and uniformly mixing to obtain a primary material;

E: putting the initial material into a compression molding machine, compressing into cylindrical granules, bagging and packaging.

The invention has the advantages that: by adopting the cedar chips, the rice hulls, the dried cow dung and the corncobs as main raw materials, the cost is low, the carbon content is high, and the heat productivity is high; the produced granular fuel has large heating value, the heating value is 4000-; meanwhile, the granular fuel does not contain sulfur and phosphorus, does not corrode the boiler, can prolong the service life of the combustion boiler, and does not generate sulfur dioxide and phosphorus pentoxide during combustion, thereby not causing acid rain, atmosphere and environment pollution; the main raw materials are clean and sanitary, so that the prepared granular fuel is tidy, the feeding and the use are convenient, the labor intensity of workers is reduced, and the labor environment is greatly improved; because the raw materials are purely natural crops and forest wastes, ash after the granular fuel is burnt is high-quality organic potash fertilizer with extremely high grade, and the organic potash fertilizer can be recovered to create profits; effectively relieve energy shortage, treat waste pollution, protect ecological environment and meet the requirement of sustainable development. In conclusion, the method has the advantages that the crop and forest waste is fully recycled, the process is simple and practical, the recovery rate of the crop and forest waste is improved, and the recycling value of the crop and forest waste is obviously improved.
