Abstract

The invention discloses high-heat environment-friendly biomass and a preparation method therefor. The method comprises the steps: 1) carrying out primary crushing on wastes of agriculture and forestry; 2) feeding the primary-crushed wastes of agriculture and forestry to a finishing crusher through a conveying belt, wherein the diameter of the finishing-crushed wastes of agriculture and forestry isnot greater than 8mm; 3) feeding the finishing-crushed material to a material regulating and mixing bunker through a pumping machine, meanwhile, adding fly ash, a sulfur fixation agent, a combustionimprover, a surfactant and a metal catalyst into a mixer, and carrying out mixing, so as to obtain a mixture; 4) uniformly mixing the obtained mixture and crushed materials in the material regulatingand mixing bunker through a conveying device, so as to obtain a raw material for granulation, wherein the raw material for granulation has the wettability of 12% to 18%; and 5) feeding the raw material for granulation obtained in the step 4) to a press-granulating production machine through a pumping machine, and carrying out granulating, thereby obtaining the high-heat environment-friendly biomass. According to the high-heat environment-friendly biomass and the preparation method therefor, resources are saved, the energy consumption is lowered, and the production value is increased.

Description

technical field [0001] The invention relates to the technical field of energy treatment and reuse, more specifically, a high-calorie and environment-friendly biomass and a preparation method thereof. Background technique [0002] Using wood fiber and straw as raw materials, the granular fuel formed by high-pressure and low-temperature compression molding through professional machinery and special technology is collectively referred to as biomass pellet fuel. Biomass pellet fuel has high calorific value and is clean and pollution-free. It is a high-tech environmental protection product that replaces fossil energy. [0003] The CO2 released by biomass pellet fuel during combustion is roughly equivalent to the CO2 absorbed by photosynthesis during its growth, so the greenhouse gas CO2 emission of biomass pellets is zero. Biomass fuel is a renewable energy source. As long as there is sunlight, the photosynthesis of green plants will not stop, biomass energy will not be exhauste...
