Biomass fuel with swine excrement and preparation method thereof

Abstract

The invention relates to a biomass fuel with swine excrement and a preparation method thereof. The fuel is prepared from the following raw materials in parts by weight: 100 parts to 120 parts of the swine excrement, 50 parts to 60 parts of sawdust powder, 30 parts to 40 parts of branches and leaves of cunninghamia lanceolata, 30 parts to 40 parts of branches and leaves of pine wood, 20 parts to 30 parts of straw fermented materials, 10 parts to 20 parts of coal dust and 10 parts to 20 parts of clay. The preparation method of the biomass fuel comprises the following steps: mixing the branches and leaves of the cunninghamia lanceolata, the branches and leaves of the pine wood and the sawdust powder to obtain a mixture 1; then mixing the mixture with the swine excrement and the straw fermented materials to obtain a mixture 2; then mixing the mixture 2 with the coal dust, the clay and the remaining sawdust powder and uniformly stirring; drying and then feeding into a granulating machine; extruding into cylindrical grains; finally baking the cylindrical grains to obtain the biomass fuel. According to the biomass fuel prepared by adopting the method disclosed by the invention, the swine excrement is developed as the fuel, so that the cost of a farm is reduced, the problem of the shortage of the fuel also can be solved, treatment ways of the excrement is added, the waste of the excrement is avoided, and the fuel can be supplied while environment protection can be achieved at the same time; moreover, the biomass fuel has significant economic benefits and environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of pollutants in the breeding process, and in particular relates to a pig manure biomass fuel and a preparation method thereof. Background technique [0002] With the increasingly serious consumption of energy resources, the increasingly tense energy resources, and the increasingly prominent environmental pollution problems, various industries have gradually strengthened their awareness of the use of renewable energy. Among them, the use of biomass energy is currently the most practical solution. Biomass is the most widespread substance on the earth, including all animals, plants and microorganisms, as well as many organic matters derived, excreted and metabolized by these living substances. Biomass energy is currently a very important energy source. Under the circumstances of rapid social and economic development, the dual nature of resource conservation and environmental friend...
