Biochar production equipment

Abstract

The invention relates to biochar production equipment, and belongs to the technical field of biochar processing equipment. The biochar production equipment 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 biochar production equipment 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 biological charcoal production equipment, which belongs to the technical field of biological charcoal 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 production equipment mainly has the following deficiencies: [0003] 1. The sealing effect of the reaction kettle is poor, the air leakage between the kettle cover and the kettle body affects the quality of the charcoal, and the reaction kettle cannot be stably erected in the combustion chamber; [0004] 2. During the reaction of the reactor, a mixture of tar, wood gas, water, etc. will be discharged, and the mixture is a high-temperature mixture. Existing biochar production equipment cannot ...

AI Technical Summary

Problems solved by technology

Existing biochar production equipment cannot separate tar and wood gas, and wood gas cannot be recycled, resulting in low resource utilization, and if it is discharged directly, it will cause great pollution to the environment;

[0005] 3. 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;

[0006] 4. After the reaction is completed, the biochar needs to be taken out of the reactor. At present, most of the biochar in the reactor is taken out by manually standing near the mouth of the reactor and using tools. The labor intensity of the workers is high, the operating safety factor is low, and the work efficiency is low. Low;

[0007] 5. Because the reactor has a certain height, it is difficult to feed materials into the reactor, which increases the labor intensity of workers;
