Problems solved by technology

[0002] Civil honeycomb has long been produced with high-priced (900 yuan / ton) anthracite as raw material and clay. To produce better honeycomb, high-priced binders, oxidants, combustion aids, desulfurizers, etc. must be added, and the production cost is high.
The price of briquette coal is about 500 yuan / ton higher than that of bituminous coal, making it difficult to gain a foothold in market competition

Abstract

The invention relates to a system and method for producing flammable carbon through humic acid clean conversion, and belongs to the technical field of energy conversion. According to the method, an indirect heating pyrolytic technology is adopted, organic macromolecule bonds of humic acid are destroyed, the humic acid with high moisture and low heating value is subjected to clean conversion to form humic acid based flammable carbon with a high heating value, and by-product combustible gas is scientifically used for relevant energy consumption equipment of production systems. Through reasonabledeveloping and utilization of rich humic acid resource, the heating value of an obtained product is far higher that in a national honeycomb briquette index standard, the ash content is far lower thanthe national honeycomb briquette index standard, and the system is mainly applied to urban and rural domestic clean fuel, changes the traditional method which takes anthracite, as a raw material, incombination with clay to produce domestic clean fuel, provides a new energy product, and has high market competitiveness.

Description

technical field [0001] The invention belongs to the technical field of energy conversion, and in particular relates to a system and method for cleanly transforming humic acid to produce flammable charcoal. Background technique. [0002] Civil honeycomb has long been produced with high-priced (900 yuan / ton) anthracite as raw material and clay. To produce better honeycomb, high-priced binders, oxidants, combustion aids, desulfurizers, etc. must be added, resulting in high production costs. The price of briquette coal is about 500 yuan / ton higher than that of bituminous coal, making it difficult to gain a foothold in the market competition. The north produces briquette coal for civilian use, and the government provides financial subsidies, while the south of Yunnan has no financial subsidies, so enterprises rely on adding more clay to reduce production costs to survive. Therefore, the briquette production plant sticks more and more. Counties in Yunnan generally add 30% of coa...
