Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle impurity removal, in particular to an impurity removal device for biomass particle production. Background Art

[0002] Biomass pellet fuel is essentially the direct combustion of biomass energy, a processed and utilized form of biomass. Direct combustion methods can be categorized as stove combustion, boiler combustion, garbage combustion, and solid fuel combustion. Solid fuel combustion is a newly popularized technology, solidifying biomass into a solidified form before burning it in traditional coal-fired equipment. Its advantages include fully utilizing biomass energy to replace coal, reducing CO2 and SO2 emissions, contributing to environmental protection, controlling greenhouse gas emissions, mitigating climate change, and reducing the occurrence of natural disasters. Biomass pellet fuel is made from straw and other materials.

[0003] Biomass pellets are made by cold-dense molding of crushed biomass straw, forestry waste and other raw materials using rollers and ring dies at room temperature. The density of the raw materials is generally 0.1-0.13t / m3, and the density of the molded pellets is 1.1-1.3t / m3, which is convenient for storage and transportation and greatly improves the combustion performance of biomass.

[0004] During the production of biomass pellets, in order to prevent impurities from entering the equipment and damaging the equipment, a series of screening processes are often required. After screening out large particles of impurities, fine dust and gravel particles also need to be screened. During screening, due to the fragility of the raw material plants after drying, a portion of the raw materials will be screened together with the gravel and dust. Although the loss of raw materials in a single screening is small, long-term accumulation will also cause more raw material losses.

[0005] Therefore, it is necessary to provide a biomass pellet production impurity removal device to solve the above technical problems. Utility Model Content
