Embodiment 1
[0110] This embodiment produces biochar. The biomass raw material 59 is cow dung from a cattle farm. The cow dung is preheated, carbonized, activated, and cooled to make biochar. 3 tons of cow dung are processed every day.
[0111] The preheating chamber 58 is located in the hot flue gas chamber 17, and both ends of the preheating chamber 58 are connected with the discharge drum 11 and the feed drum 5, wherein the discharge drum 11 is connected with the intermediate silo 13, and a sealing device 8 is installed at the connection , The feed drum 5 is connected to the gas collection chamber 3, and a sealing device 8 is installed at the connection. The mixed gas outlet 4 of the gas collection chamber 3 is connected with the air inlet 43 of the spray washing cooling tower 42 through the mixed gas pipe 41,
[0112] The length of the preheating chamber 58 is 2 meters, and the diameter is 0.8 meters. The filling rate of raw materials in the preheating chamber 58 is 45% of the volume ...

Abstract
The present invention provides a device for biochar manufacturing. The device comprises a hopper, a rotary preheat chamber, a rotary dry distillation chamber and a cooling chamber. The rotary preheat chamber is located in a hot flue gas chamber, with one end connecting to the hopper through an incoming roller and a first screw conveyor and the other end connecting to the top of a middle hopper through an outgoing roller, used to preheat the biomass raw material; the rotary dry distillation chamber is located inside a combustion chamber, with one end connecting to the bottom of the middle hopper through a front roller and a second screw conveyor and the other end connecting to a discharge chamber through a back roller, and a burner being installed at its bottom; the dry distillation chamber is used for carbonizing the preheated biomass raw material and causing it to undergo an activation reaction with steam and flue gas to form biochar; the cooling chamber is located below the discharge chamber and is used for cooling the biochar formed through the activation reaction. The biochar manufacturing device of the present invention can use livestock manure, crop stalks, bagasse and other biomass as raw material to manufacture biochar in a low-cost and industrialized manner.
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...
