Please, experts, take a look and see if this change is feasible

Previously, a zero-level buffer tank was installed for unloading the raw materials; now a tail pipe needs to be installed. Figure 1 shows the design proposed by the design institute. Can it be modified to the connection style shown in Figure 2? ? Please give some advice, thank you
Is the exhaust pipe connected to the pump outlet? ； That’s not possible, right?
Is Figure 1 not complete? Should the high-position discharge port be used as the exhaust port? Personally, I think it cannot be changed to Figure 2. The purpose of the exhaust pipe is to vent the volatile gases from the zero-level discharge tank. As shown in Figure 2, the inlet pipe of the large storage tank is inserted into the bottom of the tank; once liquid fills the tank, a liquid seal is formed, and as a result, the exhaust pipe at the zero level cannot discharge air. Even if the inlet pipe is not completely sealed, it is not recommended to make any changes. Because the pipe has a downward bend, there are dead corners. For reference! When working with producer gas, there have been accidents of flash explosions occurring when welding was carried out in dead corners at the inlet pipe of the compressor that could not be accessed.
No, it’s better to use Figure 1. Remember to close the exhaust valve after the exhaust gas in the zero-position tank has been completely discharged
The high-position discharge port above is used to connect to the top of the tank truck in order to balance the air pressure. Okay, follow the construction plans provided by the design institute.
Okay, okay, everything will be closed after unloading.
