The process of making biochar from bamboo chips mainly includes raw material preparation, pyrolysis carbonization, cooling grinding and other steps. The following is a detailed production process:
一、 raw material preparation
1. Collect bamboo scraps: Collect bamboo scraps from the bamboo processing process to ensure the cleanliness of bamboo scraps and remove impurities and soil particles.
2. Pretreatment: Initial treatment of bamboo chips, such as natural air drying or drying, to reduce its moisture content. It can usually be dried quickly and efficiently with the dryer of Jiutian machinery to quickly reduce the moisture content of bamboo chips to less than 10% to ensure the smooth pyrolysis process.
二、pyrolysis carbonization
1. Equipment preparation: pyrolytic carbonization is carried out with the carbonizing furnace of Jiutian Machinery and other equipment. The carbonization furnace of Jiutian Machinery has good sealing and temperature control ability to ensure the stability and safety of the pyrolysis process.
2. Pyrolysis process: the pre-treated bamboo chips are put into the carbonization furnace for high temperature pyrolysis under the condition of hypoxia or no oxygen. The pyrolysis temperature is generally controlled at about 500 ° C, and the heating rate can be adjusted according to the actual situation, usually 8-10 ° C/min. The pyrolysis time is generally about 2 hours to ensure that the bamboo chips are fully carbonized.
3. Gas treatment: In the pyrolysis process, some combustible gases and harmful gases will be produced. These gases need to be properly disposed of, such as collection, use or discharge to a safe area.
三、 cooling grinding
1. Cooling: After the pyrolysis is completed, the carbonized products are removed from the carbonization furnace and cooled to room temperature naturally. Pay attention to avoid quenching to prevent cracking of carbonized products.
2. Grinding: Grinding the cooled carbonized products to obtain the required size of biochar. The grinding intensity and time should be controlled during the grinding process to avoid damaging the structure and properties of biochar.
Matters needing attention
1. Safe operation: In the entire production process, safety operation procedures should be strictly observed to ensure the safety of personnel and equipment.
2. Environmental protection treatment: Proper disposal of the generated waste and pollutants to reduce environmental pollution.
3. Quality control: Quality testing and control of the produced biochar to ensure that it meets relevant standards and requirements.
Through the above steps, Jiutian Machinery's carbonization machine can be used to convert bamboo scraps into biochar products with multiple uses. These products can be widely used in soil improvement, environmental governance, energy utilization and other fields. Realize the reuse of waste biomass fuel, protect the environment and improve economic benefits!
