Production method and production equipment of biomass particles

Abstract

The invention belongs to the field of biomass energy, and in particular relates to a production method of biomass particles. In the production method, a mixture of sawdust and bamboo dust is used as the raw material. The invention further provides production equipment of biomass particles. The production equipment comprises a raw material conveying belt, a hopper, a feeding device and a granulating device, wherein the discharging end of the raw material conveying belt is above the hopper; the raw material conveyed through the conveying belt directly enters the hopper; the lower part of the hopper is connected with the feeding device; the feeding device feeds the raw material to the granulating device. The production equipment is characterized in that a stirring device is also arranged in the hopper; the stirring device comprises a rotary rod and a plurality of sets of stirring paddles; each set of stirring paddle is composed of 2-4 paddles; the paddles in the same set are at the same height; the included angle between each paddle and the plane vertical to the rotary rod is 0-15 DEG. The production method and the production equipment of the biomass particles disclosed by the invention have the advantages that the bamboo dust resource is sufficiently utilized; the novel field for manufacturing the biomass particles is opened; furthermore, glue is unnecessarily added in the manufacturing process; in addition, the heat value of the obtained biomass particles is higher than that of the pure sawdust product.

Description

technical field [0001] The invention belongs to the field of biomass energy, in particular to a production method and production equipment of biomass particles. Background technique [0002] Biomass energy is an important part of new energy. It has important characteristics such as non-pollution and renewable. Increasing the use of biomass sources can effectively reduce carbon dioxide emissions and reduce environmental pollution. Secondly, biomass energy has a wide range of sources and is easy to use. 1. The price of raw materials is low, and the waste residue left by burning is a good organic fertilizer, and the utilization of biomass energy can promote the development of ecological agriculture. [0003] One of the existing biomass energy utilization methods is to use the remaining wood chips processed by traditional wood product manufacturers to make biomass pellets. As a substitute for coal, biomass pellets made of wood chips have the advantages of high calorific value an...
