Abstract

The invention discloses a preparation method for biomass granular fuel. The preparation method comprises the following steps of: after uniformly mixing herbivorous animal waste, paper mill sludge and furfural residue, deodorizing and drying the mixture and then crushing the mixture to obtain a material A; uniformly stirring straw powder, bamboo powder, bagasse, peanut shells and the material A, then adding vinegar residues and propionic acid to uniformly stir the mixture, then leaving to stand for 10-15 hours, raising the temperature to 60-70 DEG C, insulating the mixture for 1-2 hours, ceaselessly stirring the mixture in the temperature raising and insulating processes, taking out the mixture and washing the mixture till the pH value is 6.5-7 to obtain a material B; and after uniformly mixing the material B, cottonseed meal and rapeseed meal, drying the mixture, then adding kaolin, diatomite, bentonite, calcium peroxide, aluminum hydroxide, propylene glycol, polyvinyl alcohol, anthracite and waste grease to uniformly mix the mixture, drying the mixture in vacuum till the water content of the mixture is 3-6wt% and granulating the mixture to obtain the biomass granular fuel.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a method for preparing biomass particle fuels. Background technique [0002] Biomass solid molding dyes refer to solid fuels that use agricultural production residues such as crop straws and are compressed into specific shapes by special equipment to increase their density. When using CO 2 Net emissions are approximately zero, NO X , SO 2 The low emissions are conducive to reducing the phenomenon of straw burning in vast rural areas and improving the atmospheric environment. The current preparation method of biomass solid particle fuel usually adopts a hot pressing molding method, that is, the raw material is pulverized and dried and directly added to a molding machine, and the solid particle fuel is obtained by hot pressing. [0003] However, due to the inherent high content of alkali metal elements in biomass such as straw, the ash melting point is low, and the slaggi...
