92. Why must the system be disconnected when the unit shuts down?
Without a removal system, the equipment can experience vibrations caused by pressure fluctuations, which may damage its internal components; at the same time, this can lead to the deposition of light components in the gas within the unit, resulting in liquid contamination； Usually, it is necessary to close the inlet and outlet valves and open the vent valve to relieve pressure
To avoid pressure fluctuations in the entire system caused by the shutdown of the main fan, stability can be maintained. After removing the unit from the system, it is possible to reduce the unit’s load by lowering the outlet pressure, which is beneficial for protecting the rotor and bearings.
This question relates to catalytic units. The following considerations apply: When the main fan is shut down, the system must first be isolated, that is, the outlet valve must be closed and the vent valve opened. The reason for this is to avoid pressure fluctuations in the entire unit caused by the shutdown of the main fan. By stabilizing the situation after isolating the unit from the system, it is possible to reduce the load on the unit by lowering the outlet pressure, which is beneficial for protecting the rotor and bearings.
Yes, considering it from the perspective of the catalytic device
When shutting down the main blower, the system must first be isolated—that is, the outlet valve should be closed and the vent valve opened. The reasons for this are as follows: to prevent pressure fluctuations throughout the entire plant caused by the shutdown of the main blower, thereby maintaining stability. After isolating the unit from the system, its load can be reduced by lowering the outlet pressure; this is beneficial for protecting the rotor and bearings.
