Biochar processing system

Abstract

The invention relates to a biochar processing system, and belongs to the technical field of biochar processing equipment. The biochar processing system comprises a combustion base provided with a plurality of preheating chambers and a plurality of combustion chambers, the preheating chambers and the combustion chambers are communicated with one another, a wood gas conveying pipe is arranged outside the combustion base and communicated with a plurality of branch pipes extending into the combustion chambers, one end of the wood gas conveying pipe is connected with a wood gas combustion hearth, a discharge chimney, a preheating chamber and a combustion chamber of the wood gas combustion hearth are all communicated with a smoke induced draft fan, a discharge pipeline of the reaction kettle is communicated with a cooling box body, the cooling box body is mounted on a combustion foundation, the bottom of the cooling box body is communicated with a wood vinegar output pipe and a wood gas output pipe, and the wood gas output pipe is communicated with a wood gas conveying pipe. The system is novel in structural design, capable of separating wood gas in smoke and recycling the wood gas, high in production efficiency, energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a biochar processing system, which belongs to the technical field of biochar processing equipment. Background technique [0002] Biochar refers to biomass such as agricultural and forestry waste, which is a carbon-rich product formed by pyrolysis in a reactor under the condition of anoxic and certain temperature. Biochar is extremely rich in carbon content and has a good application prospect. The existing biochar processing system mainly has the following deficiencies: [0003] 1. During the reaction in the reactor, a mixture of tar, wood gas, water, etc. will be discharged, and the mixture is a high-temperature mixture. The existing biochar processing system cannot separate tar and wood gas, resulting in low resource utilization, and if it is discharged directly, it will cause great pollution to the environment; [0004] 2. The existing biochar combustion chamber has an unreasonable structural design, and the reaction kettle...

AI Technical Summary

Problems solved by technology

The existing biochar processing system cannot separate tar and wood gas, resulting in low resource utilization, and if it is discharged directly, it will cause great pollution to the environment;

[0004] 2. The existing biochar combustion chamber has an unreasonable structural design, and the reaction kettle is directly placed in the combustion chamber for heating, resulting in long heating time and low heating efficiency;

[0005] 3. The materials in the reaction kettle will generate wood gas during the heating process. The combustion of wood gas can generate heat, which can provide heat for external equipment. The existing biochar processing system does not separate the wood gas, and the wood gas is mostly mixed with other materials. The gas is directly disposed of by external dust removal equipment, resulting in energy waste
