Device for manufacturing biological carbon

Abstract

The invention relates to a device for manufacturing biological carbon. A pre-heating chamber is positioned in a smoke gas chamber, both ends of the pre-heating chamber are respectively connected with a material outlet rolling tube and a material inlet roller, the other end of the material outlet rolling tube is connected with a middle material cabin, the lower part of the middle material cabin is connected with a material inlet chamber, the other end of the material inlet rolling tube is connected with a gas collection chamber, a mixed gas outlet of the gas collection chamber is connected with a gas inlet of a spraying washing cooling tower, a dry distillation chamber is positioned in a combustion chamber, both ends of the dry distillation chamber are respectively connected with a front rolling tube and a back rolling tube, the other end of the front rolling tube is connected with the material inlet chamber, the other end of the back rolling tube is connected with the material outlet chamber, a cooling chamber is connected under the material outlet chamber, a mixed gas outlet of the material outlet chamber is connected with a gas inlet of the spraying washing cooling tower, an external fuel combustion device and a non-condensed combustible gas combustion device are arranged in a position in the combustion chamber positioned at the lower part of the dry distillation chamber, and a hot smoke gas pipeline is arranged between the top of the combustion chamber and the bottom of the hot smoke gas chamber. The device for manufacturing the biological carbon provided by the invention can be used for industrially manufacturing the biological carbon in a pollution-free way at low cost.

Description

technical field [0001] The invention relates to a material processing device, in particular to a device for producing biochar from livestock manure, crop stalks, rice husks, peanut shells, bagasse and other biomass. Background technique [0002] Scientists refer to a carbonaceous material formed by dry distillation and pyrolysis of biomass as raw material under anaerobic conditions as "biological carbon". Biochar is a form of charcoal that can be kept in the land for a long time without being broken down into carbon dioxide. After being buried in the ground, it can last hundreds to thousands of years without disappearing. [0003] In theory, any plant or livestock excrement can be pyrolyzed, carbonized, and activated to form biochar in an oxygen-free environment. Biochar can be produced from a wide range of biomass sources, such as livestock manure, crop straw, rice husk, peanut shell, bagasse, etc. [0004] For a long time, the ratio of fertilization in my country has be...
