Composite wheat straw sawdust base biomass particle and manufacturing method thereof

Abstract

The invention discloses a composite wheat straw sawdust base biomass particle. On one hand, sawdust is subjected to carbonizing treatment and is modified; the toughness and the density of inorganic carbon particles are improved; the combustion heat value of sawdust carbon residue is improved; the volatile components in the combustion process are reduced; the sulphur content in exhausted waste gas is low; on the other hand, wheat straw, dog tail grass and oat hulls are subjected to fermentation treatment; the structure layer of the raw materials is changed, so that the compact tissue structure is formed; a high-content organic matter substance is formed; the composition ingredients of the organic matter are improved; then, modified fluorite powder and wood leftover materials are added to be continuously subjected to fermentation treatment; combustibles in the organic matter raw materials are improved; finally, other effective auxiliary agents are matched to be subjected to extrusion forming; the prepared straw sawdust base biomass particle fuel is an energy source with the lowest price in clean energy sources; the price is stable; the heat value is high; the supply is reliable; the price fluctuation risk of fossil energy sources can be avoided; the structural energy-saving benefits can also be realized.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to sawdust-based biomass particles of compound wheat straw and a preparation method thereof. Background technique [0002] With the increasing demand for energy, the widely used non-renewable energy such as oil, coal, and natural gas is facing the problem of depletion. In order to solve the energy crisis that mankind is about to face, it is necessary to develop renewable new energy sources to replace non-renewable fossil fuels. Biomass energy, as a cheap and clean renewable energy, is attracting more and more attention from people. As a large agricultural country, our country has comparative advantages in raw material supply, energy demand and government policy support of biomass energy. big advantage. The source of sawdust and straw is abundant, the cost is low, and the sulfur content of sawdust is very low. The biomass pellet fuel prepared from it as a raw material replace...

AI Technical Summary

Problems solved by technology

However, the traditional biomass pellet fuel prepared by using sawdust and straw has many defects such as low calorific value, unsafe use of slagging boilers, excessive sulfur content polluting the environment, and large ash content.
