To judge whether the pyrolysis has been completed, it is necessary to observe the temperature changes and reaction conditions. There are a few rules to judge whether the material in the reactor is dry:
1 The oil flow in the glass sight becomes smaller, the flow rate becomes slower, and the color becomes darker.
2: Observe the temperature change: pay attention to the duration and the temperature change during the constant temperature reaction stage. For example, the temperature stops rising when it no longer absorbs heat or starts to drop because of heat loss.
3:Increase the furnace firepower and increase the pyrolysis furnace temperature, but the airbag temperature drops instead.
When judging whether the pyrolysis has been completed, it is necessary to comprehensively judge by multiple aspects based on production experience. At the same time, attention should be paid to safety protection measures to avoid accidents caused by excessive temperature or other unexpected situations.
