Problems solved by technology

The current briquette fuel mainly uses biomass such as corn stalks, corn cobs, wheat straw, straw, cotton stalks, peanut shells, sawdust, wood chips, bark, etc. The texture is loose, the moisture content is large, the calorific value is low, the resources are scattered, and it is not easy to store and transportation
Moreover, the level of agricultural mechanization in most rural areas is low, and there is no one-stop machinery and equipment from biomass harvesting to fuel making. The large-scale collection and storage of biomass briquette fuel raw materials has become a "bottleneck" in the process of biomass briquette fuel processing and production. ", restricting the industrialization of biomass briquettes

Abstract

The invention discloses a method for coproducing high-humic-acid organic fertilizer by using biomass briquette fuel. According to the method, peat is taken as a raw material, and the coproducing high-humic-acid organic fertilizer by using biomass briquette fuel is co-produced according to the chemical composition characteristic of peat. The method comprises the following basic steps: crushing peat, mixing and compounding the pear, extruding the pear to form the coproducing biomass briquette, mixing ash produced by burning the coproducing biomass briquette, peat and dairy cow manure, and preparing the high-humic-acid organic fertilizer by composting fermentation. The method realizes the poly-production of the biomass briquette fuel and the high-humic-acid organic fertilizer from peat, solves the key problem that peat is mainly used as organic fertilizer and a horticultural substrate product at present and has a low added value, and meanwhile solves the industrialization requirement problems how to obtain raw materials intensively, transport and store products conveniently and meet market industrialization requirements in the neighborhood during the large-scale production of biomass briquette fuel.

Description

technical field [0001] The invention belongs to the field of research and application of coal and biomass conversion and clean energy, and in particular relates to a method for preparing biomass briquette fuel and co-producing high humic acid organic fertilizer with peat as raw material. Background technique [0002] Biomass refers to any organic matter synthesized by photosynthesis using solar energy. Biomass briquette fuel is to dry and pulverize various dispersed biomass without a certain shape to a certain particle size, and then extrude it into a certain shape with a certain density under certain temperature, humidity and pressure conditions. Tall solid fuels in the form of rods, blocks, pellets or pellets. There are currently two main types of biomass briquettes available around the world: briquettes and pellets. Raw material is the core of biomass briquette fuel, and the raw material requirement of biomass briquette fuel is to obtain nearby materials, sufficient res...
