The invention discloses a method for preparing
solid forming fuel with pig
manure as
raw material. The method comprises the steps as follows: firstly,
drying the pig
manure to enable the
moisture content of the pig
manure to be reduced to 10%-25%, then crushing the pig manure and adding the additive capable of desulfuration, deodorization and mold prevention via 2%-5%
dry basis quality of the pig manure so as to form the dried pig manure
raw material; uniformly mixing and stirring 20%-100% of the dried pig manure
raw material, 0%-80% of
biomass and 0%-20% of
coal by
dry weight to obtain the raw material mixture, and then utilizing forming
machine to perform hot-pressing formation, so as to obtain the
solid forming fuel. The method has the characteristics of simplicity, convenience, feasibility,
energy conservation and
environmental protection, high treatment efficiency, low production cost, and high convenience for large-scale industrialized production, and the
solid forming fuel has no
odor, is not easy to
mildew, is convenient in transportation and storage and high in
combustion efficiency and has fewer secondary
pollutant emissions. Therefore, harmless treatment and
resource utilization of the pig manure are realized, and the problem about treatment and disposal of the excessive pig manure can be effectively solved.
