The tank is equipped with a gas phase pipe; it was designed by a Canadian expert. I’ve seen that the material feeding in this case is very steady. The design from Germany, on the other hand, results in material being fed in pulses, and there is a lot of noise and impact force at the site. We plan to change the setup to use design C.
What about the balance tube? Negative pressure distillation doesn’t have pressure balance pipes – how is material discharged?
Both B and C are prone to poor material discharge, especially B – the gas phase in the tank cannot be expelled, so how can material be discharged? Will blowing up the tank be necessary?
It’s a simple sketch; the tank has vapor pipes. The phenomenon observed in B is that the material is discharged in pulses, as if a siphon effect is occurring.
The pressure in the receiving tank below you is not consistent with the system pressure; therefore, a balance pipe needs to be added at the top of the tank to connect it to the system
Option A: Connect vacuum there where there is no condenser? Connect a pipe from the non-condensing steam pipeline to the receiving tank.
The balance tube is the connecting pipe between the top of the receiver tank and the non-condensable gas pipeline of the condenser
