Preparation of solid bio-fuel block

Abstract

The invention relates to a preparation method of a solid bio-fuel brick, and the preparation method comprises the steps as follows: reusing agroforestry plant processing waste residues, obtaining products of biological tar, biomass carbon powder and the like by high-temperature oxygen-free pyrolysis, evenly mixing the products with MgO and turpentine oil, compression molding and evenly coating a water-proof coating on the surface thereof. The mass percentages of various substances of the biological solid fuel are as follows: 5-40 percent of biological tar, 20-50 percent of biomass carbon powder, 5-20 percent of MgO and 2-15 percent of turpentine oil; and the mass percentages of various substances of the water-proof coating are as follows: 80-95 percent of paraffin and 5-20 percent of turpentine. The biological solid fuel has the advantages of flammability, light weight, waterproof property, high calorific value, high flame, full combustion, and the like; the biological solid fuel is lighter and more flammable than coal; compared with wood, the biological solid fuel is easy to carry, high in calorific value and long in burning time. The solid bio-fuel brick can be used in outdoor and wild places, and mainly applicable to emergency aid, heating and cooking for sudden accidents.

Description

Technical field: [0001] The invention relates to a method for preparing solid biofuel block, in particular to a method for preparing biosolid fuel from the product of high-temperature anaerobic pyrolysis using agricultural and forestry plant processing waste residues as raw materials. Background technique: [0002] In recent years, with global climate change, severe weather has occurred frequently, coupled with the occurrence of large-scale geological disasters, paralyzing infrastructure such as electricity and transportation. Normal heating and cooking. For this emergency, if a light, flammable, heat-resistant solid fuel is developed, the situation will be greatly improved. Moreover, this solid fuel is also very suitable for long-term field operations, army camping training, travel and so on. [0003] Biomass is a renewable resource that can be converted into other high-value energy sources. In my country, a large amount of agricultural and forestry plant processing biom...

Problems solved by technology

In my country, a large amount of agricultural and forestry plant processing biomass waste (including straw, fuelwood, etc.) is produced every year, and the output of agricultural straw is about 800 million tons per year. In addition to straw returning to the field and feed, the amount of resources that can be used as energy is about 400 million tons, and the reasonable annual mining of fuelwood is 160 million tons, but such a large resource is not fully and efficiently utilized, and is often burned on the spot, seriously polluting the environment
