Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problems of low energy density, unstable combustion rate, low combustion efficiency and insufficient combustion of biomass itself, in addition, biomass is very easy to absorb moisture and cause damp and mildew. Biomass pellet fuel cannot meet the requirements of moisture-proof and mildew-proof, and it is easy to absorb moisture and mildew during long-term storage. A preparation method for biomass pellet fuel is provided

Embodiment 1

[0036] A method for preparing biomass pellet fuel, comprising the following steps:

[0037] Step 1: Prepare pine wood, straw, camphor wood, and rice husk, place the woody materials in the storage bin, put the beetles into the storage bin after mixing, and the beetles live with the woody materials for 7-12 days;

[0038] Step 2: Take out the woody raw material, put it into the fermentation bin for fermentation, and take it out after the fermentation is completed;

[0039]Step 3: After taking out the wooden raw material, add the following auxiliary materials into the wooden raw material, including: 10-20 parts by mass of animal manure, 10-20 parts by mass of bamboo charcoal, 20-40 parts by mass of anthracite, 10-20 parts by mass of binder, 5-10 parts by mass of epoxy resin; 5-10 parts by mass of foaming agent, the epoxy resin and foaming agent are now pretreated, and then the processed material is mixed with all raw materials;

[0040] Step 4: Convey the stirred material to the...

Embodiment 2

[0045] In step 1, prepare pine wood, straw, camphor wood, and rice husk, and place the wooden raw materials in the storage bin. Before placing them in the storage bin, the pine wood, straw, camphor wood, and rice husk need to be screened and dried, including:

[0046] S1: Pine wood, straw, camphor wood, and rice husk need to prepare enough raw materials in order not to affect the production of fuel, and at least 15 days or so of raw material production needs must be guaranteed;

[0047] S2: Then crush and screen the pine wood, straw, camphor wood, and rice husk respectively, and transport the raw materials to the screening machine through the auger conveyor for screening, and screen out larger pieces of wood or wooden nails, soil and other miscellaneous materials. thing;

[0048] S3: After being screened, it should be transported to the tumble dryer through the auger conveyor for drying by hot air;

[0049] S4: After the raw materials are dried, there may be a lot of moisture...

Embodiment 3

[0052] In step 1, place the beetles into the storage bin. The beetles live together with the wooden materials for 7-12 days. The beetles are made of Asian longicorns, and 10-15 Asian longicorns are put into each square meter of the raw materials. No closed type is used during this period. A storage bin to ensure that longhorns can survive normally in the storage bin.

[0053] In the present invention, longicorns can be cultured and released in batches. Asian longicorns can decompose lignin, and this beetle can decompose lignin of trees, leaving sugar cellulose composed of glucose, which is decomposed into The small pieces are then fermented to produce ethanol. The presence of ethanol in woody raw materials can greatly improve the flammability of biomass particles and make the combustion effect of biomass particles better.

Abstract

The invention discloses a biomass granular fuel preparation method, and relates to the field of biofuels. The method comprises the following steps: 1, preparing pine wood, straw, camphorwood and ricehusk, placing a wood raw material in a storage bin, mixing, placing beetles in the storage bin, and allowing the beetles and the wood raw material to live for 7-12 days; and 2, taking out the wood rawmaterial, putting the wood raw material into a fermentation bin for fermentation, and taking out the wood raw material after fermentation. Asia longicorn and the wood raw material are placed together, lignin in the wood raw material is decomposed and fermented by utilizing the Asian longicorn, the Asian longicorn can decompose lignin, the beetles can decompose the lignin of trees, carbohydrate cellulose composed of glucose is left, the glucose is decomposed into small pieces and then fermented to generate ethyl alcohol, ethyl alcohol exists in wood raw materials, the combustibility of biomassparticles can be greatly improved, and the combustion effect of the biomass particles is better.

Description

technical field [0001] The invention relates to the field of biofuels, in particular to a method for preparing biomass particle fuels. Background technique [0002] Biofuels generally refer to solid, liquid or gaseous fuels composed or extracted from biomass, which can replace gasoline and diesel produced from petroleum, and are an important direction for the development and utilization of renewable energy. The so-called biomass refers to the use of air, water, Various organisms produced through photosynthesis such as land, that is, all living and growing organic substances, including plants, animals and microorganisms, are different from traditional fuels such as oil, coal, and nuclear energy. These emerging fuels are renewable fuels . [0003] Biomass fuels that use agricultural and forestry wastes, such as straw, sawdust, bagasse, and rice bran, as the main raw materials have the advantages of high efficiency, cleanliness, and no pollution. In addition, biomass can easi...
