When the supercharger is shut down, the external heat exchanger lifting air pipe will not immediately return the catalyst, right?

After all, the main fan has not stopped yet. In other words, if the supercharger is shut down and the external heat extraction lift damper is temporarily left open, is it okay? If there is time to relax, how long will it be?
Whether to pour the catalyst depends on whether the booster air self-protection or the booster anti-surge valve is opened in time. When the pressure of the two devices is stable, the main air can replace the booster air in a short time.
The current device design generally prevents the catalyst from coming over, but it does not necessarily mean that it will not. ESD will fully close the sleeve fluidizing air, external heat fluidizing air valve and booster air outlet check valve, which will not affect the supercharger. However, it is very possible that the catalyst will flow back to the regulating valve. Generally, the superchargers of small devices are centrifugal and have low power, so there is no need to open the anti-surge vent valve. There is a non-purified air line at the root of the external heat collector and the sleeve fluidized air regenerator. It can be opened slightly so that when the supercharger is stopped, the catalyst will not flow back quickly. Is there an outlet pressure control valve at the outlet of the supercharger, which can return the supercharged air to the main air? Generally, there is no one-way valve on this pipeline. If the supercharger stops, this valve can be opened to allow the main air to replace the supercharged air for a short time. As for accident steam, it is best not to use it.
There is usually a one-way valve to prevent backflow
When the supercharger is shut down, the supercharged air self-protection action will be activated. The one-way valve of the supercharged air outlet will be fully closed, and the catalyst will not flow back in the short term. Keep the non-purifying damper open for a long time.
