System and method for biomass fuel production

Abstract

The invention discloses a system and method for biomass fuel production. The system comprises a drying system, a smashing system and a pelletizing system. The discharging end of the drying system communicates with the feeding end of the smashing system through a pipeline. The discharging end of the smashing system communicates with the feeding end of the pelletizing system through a pipeline. Thedrying system comprises a drying drum body, a multi-level cyclone separation device, a first air guide pipe, a second air guide pipe and a multi-level dust settling chamber. A roller body is arrangedinside the drying drum body, and one end of the roller body communicates with the multi-level cyclone separation device through the first air guide pipe. The multi-level cyclone separation device communicates with the multi-level dust settling chamber through the second air guide pipe. Transferring is achieved through a hoister among all the systems, and the automatic production process from woodchip raw materials to final products can be facilitated. Meanwhile, materials can communicate through the pipelines for transferring in the whole production process, raised dust produced by the materials can be avoided, environmental pollution is reduced and explosion potential safety hazards caused by the high dust content in the air in production are lowered.

Description

technical field [0001] The application relates to a biomass fuel production system and method, which belongs to the field of biomass fuel production. Background technique [0002] Biomass fuel (also known as biomass pellet fuel) is a block-shaped environmentally friendly new energy fuel material produced by processing straw, straw, rice husk, peanut shell, corn cob, camellia husk, cottonseed husk, etc., as well as "three leftovers". . The diameter of biomass particles is generally 6-10 mm, and the ignition point is about 250 °C. Biomass fuel needs to be dried, and most of the existing drying equipment is drum drying. [0003] During the drying process, the temperature of the hot air is above 300°C, and the biomass fuel often rubs against each other or the inner wall of the cylinder in the drum drying cylinder, resulting in spontaneous combustion due to excessive local temperature of the material. After spontaneous combustion, biomass fuel is prone to produce a large amoun...

AI Technical Summary

Problems solved by technology

In the process of sawdust granulation, the mechanical vibration of the sawdust granulator is large, and a large amount of steam and dust are generated, which affects the workshop environment.

In addition, the transfer of materials from raw materials to finished products will also consume a certain amount of manpower, thereby affecting production efficiency
