Production process of biomass pellet fuel and complete equipment

Abstract

The invention discloses a production process of a biomass pellet fuel and complete equipment. The production process comprises the following steps of: 1, crushing: crushing biomass raw materials until the granularity is below 200nm; 2, tempering and curing: helically stirring, pressurizing and extruding, mutually rubbing, kneading and crushing, and mechanically crushing the crushed biomass, wherein the granularity and the flexibility of the biomass are improved, at this moment, the biomass can be naturally raised, the active organic matters of bound water, tar oil and the like inside the biomass can be extruded out to become a natural bonding agent; 3, drying and stirring: stirring and drying the tempered and cured biomass raw materials to ensure that the water content is controlled to be 15-25 percent; 4, extruding and forming, wherein the biomass pellet fuel with granularity of below 20nm is obtained; and 5, air-cooling and drying, wherein the water content of the biomass pellet fuel is controlled to be below 10 percent. The invention has the advantages of good continuity of produced biomass pellet fuel, wide application range of the biomass raw materials, lower energy consumption, easiness of formation and high production efficiency; and the formed granule has smaller volume and is convenient for transportation and storage.

Description

technical field [0001] The invention relates to a production process and a complete set of equipment for biomass particle fuel. Background technique [0002] The energy problem is one of the decisive factors affecting social and economic development. Solving the energy problem will solve the power problem of economic development. The shortage of conventional energy supply in my country has seriously affected the rapid development of social economy, and the large-scale concentrated use of fossil energy, A large amount of carbon dioxide, sulfur dioxide, nitrogen oxides and other substances are released, which has caused harm to the living environment of human beings. For this reason, countries all over the world have vigorously strengthened the development and research of renewable energy technologies. As the fourth largest energy resource, biomass occupies an important position in renewable energy. The development of biomass energy can not only supplement the shortage of conve...

Problems solved by technology

[0004] When using, due to the wide range of biomass raw materials, including straw, corn stalks, branches, bark, wood particles, etc., there are certain differences in their natural size and flexibility. Drying and repeated crushing can control the particle size below 10mm, and more equipment is used, resulting in high energy consumption and low production efficiency; at the same time, it is necessary to add adhesive biomass raw materials and stir them to mix Uniformity, resulting in cumbersome process and difficult molding, and the density of the particles after molding is small, the volume is large, and it is not convenient for transportation and storage
