The carbonization process of rice husk is a process of converting organic matter in rice husk into carbonaceous material after pyrolysis and gasification reaction at high temperature. The following are the detailed steps of rice husk carbonization:
一、Preliminary preparation
1. Rice husk collection: First of all, a large number of rice husks need to be collected as raw materials. The husks are usually a byproduct of rice processing.
2. Cleaning and drying: Clean the collected rice husks to remove impurities and dust. Then, the rice husk is dried to a certain moisture content at the appropriate temperature, which usually needs to be dried in the oven at about 100 ° C for a period of time to ensure that the rice husk can be evenly heated during the carbonization process.
二、the carbonization process
1. Equipment selection: The carbonization furnace of Jiutian machinery is selected for the carbonization of rice husks. The carbonization furnace of Jiutian machinery has good sealing and temperature control ability to ensure the smooth progress of carbonization process.
2. Temperature and atmosphere control: the dried rice husks are sent into the carbonization furnace, and the pyrolysis and gasification reactions occur in a relatively closed environment by controlling the temperature and atmosphere in the furnace (such as anoxic environment). In this process, the organic material in the rice hull will gradually lose oxygen atoms, forming a high-carbon structure.
Temperature range: Carbonization temperature usually needs to be adjusted according to the specific equipment and the quality of the rice husk, but it is generally carried out at high temperatures, such as between 500 ° C and 900 ° C.
o Atmosphere control: Oxygen deprivation is maintained in the furnace to promote the carbonization of rice husks without complete combustion.
3. Duration: The carbonization process needs to continue for a certain time to ensure that the rice husk is fully carbonized. The specific time depends on the temperature in the furnace, the quality of the rice husks and the performance of the equipment.
三、post-processing
1. Cooling and collection: After carbonization is completed, the carbonization furnace is naturally cooled to room temperature, and then carbonized rice husks are collected. At this point, the carbonized rice husks have been transformed into a black, porous, carbonaceous material.
2. Screening and grading: According to needs, carbonized rice husks can be screened and graded to obtain carbonized products of different particle sizes.
四、 Precautions
1. Safe operation: The carbonization process involves high temperature and possible harmful gas emissions, so safe operation procedures must be strictly observed to ensure the safety of personnel and equipment.
2. Environmental protection treatment: the waste gas, waste water and waste residue generated during the carbonization process need to be properly treated in accordance with environmental protection requirements to reduce environmental pollution.
3. Quality control: The quality of carbonized rice husks is affected by many factors, such as raw material quality, carbonization temperature, time and so on. Therefore, the parameters need to be strictly controlled in the carbonization process to ensure the quality and stability of the product.
In summary, the carbonization of rice husks is a complex process that requires careful design and operation. Through reasonable carbonization treatment, rice husk, an agricultural waste, can be converted into valuable carbonized materials to achieve resource reuse and environmental protection.
