Embodiment Construction

[0038] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0039] Such as figure 1 Shown, a kind of preparation method of compact biomass particle comprises the following steps:

[0040]S1. Raw material pretreatment: Mix crop straw, bagasse, bamboo chips, wood chips, combustion-promoting agent, anti-slagging agent, and aquatic plants to obtain mixed raw materials, and then heat them under air-isolated conditions. The heating temperature is controlled at 100-110°C, finally chop the mixed raw materials, and control the water content of the mixed raw materials at 13%-15%;

[0041] S2. Filtration: screen the large particles in the chopped mixed raw materials through a screen to remove the small particles;

[0042] S3, crushing: the mixed raw material is transported to a high-speed p...

Abstract

The invention provides a preparation method of compact biomass particles, belongs to the technical field of biomass particles, and solves the technical problems that raw materials are loose, short incombustion time and the like. The preparation method of the compact biomass particles comprises the steps as follows: S1, raw material pretreatment: mixing crop straw, bagasse, bamboo dust, sawdust, acombustion promoter, a slagging inhibitor and aquatic plants to form a mixed raw material, heating the mixed raw material under an air isolation condition, controlling the heating temperature at 100-110 DEG C, finally, chopping the mixed raw material, and controlling the moisture content of the mixed raw material at 13%-15%; S2, filtration: screening large-particle substances in the chopped mixedraw material by a screen, and screening out small particles; S3, crushing: conveying the mixed raw material to a high-speed crusher by a belt conveyor for crushing to prepare fine powder; conveying the fine powder by the belt conveyor continuously and drying the fine powder by a drying oven at 60-70 DEG C to prepare a dried material.

Description

technical field [0001] The invention belongs to the technical field of biomass granules, in particular to a preparation method of compact biomass granules. Background technique [0002] Biomass fuel is a block-shaped environmentally friendly new energy produced by processing straw, straw, rice husk, peanut husk, corncob, camellia oleifera husk, cottonseed husk, etc., as well as "three leftovers". It is convenient for storage and transportation, and greatly improves the combustion efficiency. Therefore, the convenience of using bioenergy particles is comparable to that of gas, oil and other energy sources. The existing biomass particles with straw, straw, rice husk, peanut husk, corncob, camellia husk, and cottonseed husk as the main raw materials have low combustion value and low combustion efficiency. [0003] During the combustion process, because the extrusion is relatively loose, or becomes loose during transportation, it will burn out in a short time during combustion,...
