Systems and methods for biofuel production

Abstract

This application discloses a system and method for biomass fuel production, including: a drying system, a crushing system and a granulation system, the discharge end of the drying system is connected with the feed end of the crushing system; the discharge end of the crushing system The material end is connected to the feed end pipeline of the granulation system; the drying system includes: the drying drum body, the multi-stage cyclone separation device, the first air guide pipe, the second air guide pipe, and the multi-stage dust reduction chamber; the drying drum machine There is a cylinder body inside the body, one end of the cylinder body is connected with the multi-stage cyclone separation device through the first air duct; It is easy to realize the automatic production process from wood chip raw materials to final products. At the same time, during the whole production process, the materials are connected through pipelines for transfer, which can avoid the dust generated by the materials, reduce environmental pollution, and reduce the production due to excessive dust content in the air. High risk of explosion safety hazard.

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, corncob, 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 amount...

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
