Description

TECHNICAL FIELD

[0001] The utility model relates to a wood chip particle drying device belongs to the technical field of drying device. BACKGROUND

[0002] The wood chip particle drying device is an important equipment in the production of biomass energy, and is specially used for reducing the moisture content in the wood chip particles. The wood chip particles processed just now usually contain a high moisture content, and if directly stored or used, it is easy to cause mildew, deterioration, combustion efficiency reduction and other problems. The drying device quickly removes the moisture in the particles through high-temperature airflow, so that the moisture content is reduced from the initial 30%-50% to 8%-15%, thereby ensuring the storage stability, transportation safety and combustion performance of the particles. This equipment is widely used in wood processing plants, biomass fuel production enterprises and environmental protection energy projects, and can significantly improve the economic value and practicality of the wood chip particles. In actual use process, the drying effect of the wood chip particle drying device is often uneven. Because the initial humidity of the wood chip particles is unevenly distributed, some particles may have a higher moisture content due to more water contact during cutting or crushing, while other particles are relatively dry. In addition, the flow distribution of hot air in the drying process, the accumulation state of particles in the equipment and the change of feeding speed will all affect the efficiency of moisture evaporation. Some particles in certain areas may quickly dehydrate due to direct hot air impact, while other particles may still contain more moisture due to difficulty in fully contacting hot air. This uneven drying effect will cause large differences in the moisture content of the same batch of particles, and some particles may be over-dried and become fragile and pulverized, increasing processing loss; while another part of the particles may still contain a high moisture content, which is easy to mildew and clump, affecting the subsequent combustion efficiency or storage quality. This uneven drying problem is particularly evident in continuous production, and the operator needs to closely monitor the drying state of the particles to ensure that the overall quality meets the requirements.
