Could you please explain in detail the function of raw material self-protection? Thank you
In simple terms, it means that the raw material supply is automatically cut off; in the event of an accident, such as a disruption in the main air supply or an insufficient amount of raw material, an automatic shutdown mechanism takes effect, thereby preventing other accidents caused by slow manual cutting of the material supply.
Agree with the person above; it’s important to protect people’s safety and property
The original purpose of self-protection design is to ensure the safe production and operation of the device, as well as to protect other equipment from damage.
Raw material protection involves automatically shutting off the raw material feed in emergency situations, thereby preventing a large amount of raw material from entering the lift pipe after the two-stage fluidization is interrupted
Self-protection can be imagined as a fuse or a relay protector~ Their function is similar; both are meant to safeguard the safety of people, machines, and materials in the downstream processes!
Here, the conditions for self-protection of the crude oil involve self-protection of the main air supply, as well as self-protection driven by the two reactors; another condition is self-protection when the feed rate is low. However, we have removed this condition
