Pressure-reducing flashing
Thread Content
Is there a direct coexistence of gas and liquid after the liquid passes through the throttle valve? Speed increases, pressure decreases – how does pressure change during fluid flow?
The pressure decreases; if the pressure doesn’t decrease, it can’t flow that fast
This has been discussed on this forum before; you can search for it
After the flow is blocked, the pressure must decrease
Principle: It mainly relies on the fact that when pressure is applied, the vapor pressure decreases, allowing more solvent (usually water) to flash into a gaseous state, thereby achieving concentration. Structure: Very simple. The diameter should be a bit larger; it’s a bit like a cyclone separator. Chemical suppliers certainly need to maintain a certain level, otherwise the liquid will leak out as well. Vaporization occurs when saturated water under high pressure is introduced into a container at lower pressure; the sudden drop in pressure causes this saturated water to turn into both saturated steam and saturated water at the pressure of the container.
