Problems solved by technology

[0003] Due to the wide range of biomass raw materials, including straw, corn stalks, branches, bark, wood pellets, etc., there are certain differences in their natural size and flexibility. When granulating materials with poor flexibility, it is easy to The particles produced are poor in quality, easy to break, and difficult to store. At the same time, the combustion effect of the biomass pellet fuel produced by the existing production process needs to be improved, and its production process is too complicated, and the waste of resources is large. Therefore, in this field The technician provides a kind of production technique of biomass particle fuel, to solve the problem raised in the above-mentioned background technology

Embodiment 1

[0028] A production process of biomass pellet fuel, comprising the following steps:

[0029] S1. Raw material pretreatment: first air-dry the material, and then use a pulverizer to crush different types of materials to less than 200mm;

[0030] S2. Drying and dust removal: use a dryer to dry the crushed material of S1 to keep the water content below 15%, and then remove dust from the material after drying to remove powder with a particle size of less than 0.1mm;

[0031] S3. Screening and material separation: use drum sieve to screen and separate the pulverized materials, and then dry and dehumidify the separated materials to obtain materials with different particle sizes;

[0032] S4. Stirring and granulation: Put different types of small particle size materials in S3 into the mixer for uniform mixing. The time is controlled within 30 minutes. During this period, add binder to the mixer until the mixing is uniform, and then convey the stirred materials Enter the pelletizing ...

Abstract

The invention discloses a production process of a biomass particle fuel, and relates to the technical field of production of biomass particle fuels. The production process comprises the following steps: S1, pretreating raw materials; S2, drying and dedusting; S3, screening and distributing; S4, stirring and granulating; and S5, dedusting and screening. Compared with the prior art, a given amount of binder is added in the stirring and granulating process, so that in the granulating process of the material, the adhesion is high, and the cracking is unlikely to occur; the adopted binder is an environment-friendly binder, so that the biomass particle fuel is small in pollution when in combustion, the cost is low, the storage is also convenient, the bacteria breeding can be inhibited, and the mustiness can be prevented; moreover, a given amount of coal powder is added in the stirring process, so that the combustion heat value of the biomass particles can be improved, the combustion qualitycan be improved. According to the production process provided by the invention, the biomass particle fuel with high quality can be obtained, the production efficiency is high, the resource waste is less, and the failure rate is low.

Description

technical field [0001] The invention relates to the technical field of production of biomass particle fuel, in particular to a production process of 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 c...
