Focus on carbon equipment
The micro-negative pressure adjustment of the continuous carbonization machine is a key step, which is related to the stability of the carbonization process and the quality of the carbonized product. The following are specific methods for adjusting the micro-negative pressure of the continuous carbonization machine:
1. Adjust the excess air volume:
During the micro-negative pressure adjustment process of the continuous carbonization machine, it is necessary to adjust the excess air volume of the inlet gas to offset the hot air volume out of the furnace, so as to achieve a stable micro-negative pressure state.
Under normal circumstances, the excess air volume should be set to be about 3% larger than the hot air volume out of the furnace to ensure the stability of the internal air flow.

2. Adjust the hot air volume out of the furnace:
The hot air out of the furnace is the power source inside the carbonization machine. Correctly setting the hot air volume out of the furnace can improve the internal air flow and improve the thermal efficiency of the carbonization machine.
If the air flow inside the carbonization machine is still unstable after adjusting the excess air volume, you can try to adjust the hot air volume out of the furnace to achieve a better micro-negative pressure state.
3. Check the sealing of the carbonization machine:
Air leakage in the furnace shell is one of the important reasons for the loss of control of the micro-negative pressure inside the carbonization machine.
In the process of adjusting the micro-negative pressure, it is necessary to carefully check the sealing of the carbonization machine, including checking the details such as door sealing and exhaust duct to ensure that there is no air leakage.
4. Avoid frequent adjustment of parameters:
When adjusting the micro-negative pressure, avoid blindly and frequently adjusting parameters such as over-air volume, hot air volume out of the furnace and air leakage of the furnace shell.
Frequent adjustment may cause unstable air flow inside the carbonization machine, which will affect the product quality and the service life of the carbonization machine.
5. Pay attention to safety:
When adjusting the micro-negative pressure, it is necessary to pay attention to the safety performance of the carbonization machine.
Especially after the carbonization machine is started, the micro-negative pressure adjustment should be carried out after the equipment runs stably for a period of time to ensure the stability and safety of the equipment.
6. Follow the operating specifications:
The operator should follow the operating specifications of the continuous carbonization machine to ensure the accuracy and safety during the adjustment process.
If necessary, you can refer to the equipment manual or consult professional technicians.
In summary, the micro-negative pressure state of the continuous carbonization machine can be effectively adjusted by adjusting the over-air volume, adjusting the hot air volume out of the furnace, checking the sealing of the carbonization machine, avoiding frequent parameter adjustments, and paying attention to safety. This can not only improve the efficiency and product quality of the carbonizer, but also extend the service life of the carbonizer.
