Composite sawdust-based biomass particles of waste cotton clothes and preparation method of particles

Abstract

The invention discloses composite sawdust-based biomass particles of waste cotton clothes. On one hand, sawdust is subjected to carbonization treatment and then modified, therefore, the toughness and the density of inorganic carbon particles are improved, the combustion heat value of sawdust carbon residues is increased, volatile components in the combustion process are decreased, and the sulphur content of exhaust gas is low; on the other hand, rice straw, sweet potato vines and sorghum stalks are subjected to fermentation treatment, therefore, the structural layer of the raw materials is changed to form the compact tissue structure, high-content organic matter is generated, and components of the organic matter are increased; the materials are continuously subjected to fermentation treatment by adding modified dolomite and the waste cotton clothes, then combustibles in the organic matter raw materials are increased, and lastly the materials are subjected to extrusion forming by being compatible with other effective auxiliaries. In this way, the prepared biomass particles have the advantages of being low in cost, good in toughness, long in service life, resistant to sun, not prone to corruption and the like.

Description

technical field

[0001] The invention relates to the technical field of biomass fuels, in particular to a sawdust-based biomass particle compounded with waste cotton clothes 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 ma...
