Description

Technical Field

[0001] The utility model relates to the technical field of biomass particles, in particular to a biomass particle machine with dust removal and dehumidification functions. Background Art

[0002] Biomass pellet machine is a kind of equipment used to process biomass raw materials such as sawdust, straw, rice husk, bark, etc. into high-density pellet fuel. This machine is usually divided into two types: flat die biomass pellet machine and ring die biomass pellet machine. They can convert the raw materials into small stick-shaped solid pellet fuel through steps such as crushing, pressurization, densification, and molding. The working principle of the biomass pellet machine is to extrude the raw materials using rollers and ring dies at room temperature to make pellet fuel. The density of this pellet fuel is greater than 1.1, which is convenient for transportation and storage. At the same time, the combustion performance is improved, which helps to reduce dependence on fossil energy and atmospheric emissions. However, the ring die biomass pellet machine will produce too much water vapor and dust during the extrusion granulation process. The existing pellet machine has poor dust removal and dehumidification effects, which is not conducive to the normal operation of the pellet machine. Utility Model Content
