The invention discloses a biomass type carbon, which includes biomass carbon powder, a combustion promoter, a proppant and an adhesive. The biomass type carbon can realize biomass carbon powder moulding, and then can achieve further development and utilization of biomass carbon, and has the characteristics of high calorific value, low volatile component, long combustion time and ultra-low emission. At the same time, the invention also discloses a biomass type carbon processing technology, the technology has simple process, can achieve industrial production, and is convenient for popularizationand utilization.

Description

technical field [0001] The invention relates to the technical field of biomass energy, in particular to a biomass-type carbon processing technology. Background technique [0002] At present, my country's agricultural and forestry waste resources are the most abundant in the world. Every year, hundreds of millions of tons of straw cannot be effectively treated. In the harvest season, straws are often burned on site, which seriously pollutes the environment and causes a great waste of resources. Agricultural straw carbonization technology is an effective form of straw resource utilization, which can convert agricultural and forestry straw into high-quality solid fuel. Through straw pyrolysis carbonization technology, waste straw can be converted into gas and biochar, which can provide clean energy , and can effectively return to the field and sequester carbon, with good economic and environmental benefits. [0003] The further development and utilization of biomass charcoal n...

Problems solved by technology

[0003] The further development and utilization of biomass charcoal needs to be shaped, but there are obvious defects in the existing biomass charcoal forming technology: one part, the molding fuel is prepared by mixing biomass fuel and soil material. CN107324773A discloses a biomass charcoal-based environmental protection Brick and preparation plan, the main raw materials are 35-45% of bio-carbon black, 55-65% of soil material, forming aids bentonite, fulvic acid powder, and cassava powder; although the preparation cost is low and it is easy to burn completely, but due to the addition of a large amount of The soil material will cause the overall calorific value of the molding fuel to be low, and the use effect is not ideal

In the other part, using biomass charcoal powder as the main raw material and using additives such as binders together can obtain briquette fuel with high calorific value, but its combustion effect is not ideal, and the density and particle size of biomass charcoal powder are small. The structure is compact after being molded with adhesive, so that the combustion process is not easy to fully burn, and the combustion process is easy to collapse, which is beneficial to gas circulation, resulting in unsatisfactory combustion effects; as disclosed in CN108277055A, a method for preparing biomass carbon powder molding fuel , through the cooperation of biomass carbon powder, binder, adhesion promoter, adhesion enhancer and water to form a briquette fuel, although the briquette fuel has high compressive stress and anti-drop strength, but the briquette fuel is not easy to achieve complete combustion, resulting in resources waste

[0004] Therefore, it is an urgent problem for those skilled in the art to provide a biomass-type charcoal processing technology that can obtain briquettes with high calorific value, long combustion time and sufficient combustion.
