Abstract

The invention discloses a preparation method of a carbon-base efficient organic-inorganic compound fertilizer. The preparation method comprises the following steps: (1) material mixing: adding a solid carbon additive into a biomass raw material in a mass ratio of 5%-8%, wherein the solid carbon additive contains the following components in percentage by weight: 50%-60% of diatomite, 20%-30% of calcium oxide and 15%-30% of magnesite powder; (2) pyrolysis and gasification: carrying out pyrolysis and gasification on the biomass raw material and the solid carbon additive in a gasification furnace so as to obtain biomass fuel gas containing partial impurities, and discharging carbon residues; (3) gas separation: purifying the biomass flue gas so as to separate wood tar and wood vinegar liquid; and (4) batching: mixing 40%-60% of the carbon residues, 10%-20% of mixed liquid of the wood tar and the wood vinegar liquid, 20%-35% of an inorganic-nitrogen phosphorus-potassium fertilizer and 2%-5% of diatomite. According to the preparation method, the inorganic fertilizer and the residues obtained after the biogas regeneration can be efficiently utilized, the obtained compound fertilizer is capable of increasing soil aggregates and improving the air permeability of soil and has sterilization and desinsection effects, the utilization rate of a crop to the fertilizer is increased, the resource consumption is low, and comprehensive economic benefits are increased.

Description

technical field [0001] The invention relates to a method for preparing compound fertilizer, in particular to a method for preparing organic-inorganic compound fertilizer by using biomass raw material as the main raw material. Background technique [0002] With the improvement of the awareness of environmental protection of the whole people, a large amount of biomass resources such as straw are moving towards the road of comprehensive utilization. Biomass pyrolysis and gasification to produce gas-fired power generation has become an inevitable direction for the development of renewable energy. However, after pyrolysis and gasification, a large amount of ash, wood tar and wood vinegar will not be processed, which will easily cause secondary pollution to the environment; while chemical elemental fertilizers, such as nitrogen fertilizers, phosphorus fertilizers, and potassium fertilizers, have high nutrient content and quick effect, but their The release speed is fast, the crops...
