U-bend in the feed pipeline of the desulfurization regeneration tower
Thread Content
Why do both the feed line and the air inlet line for the desulfurization regeneration tower need to reach the top of the tower before feeding from the bottom? Why does it need to be this tall?

If the injector is lowered, air cannot be drawn in
“”Air lines are used to prevent liquid from flowing back (backflow). “” Hello, what about the feed pipeline?
Hello, then why is it the feed pipeline?
The feed pipe is inserted from below so that air can dissolve more effectively into the liquid, allowing for sufficient time for the reaction to take place.
Hello, I mean why does the feed pipeline have to be the same as the air pipeline – why must it first reach the top of the tower and then come down from the bottom? Why is this height required?
You need to first understand why the air pipeline and the liquid inlet pipeline are combined – this is mainly to use the high-speed jet of liquid to create a vacuum that draws air into the regeneration tank. If the two pipelines are separated, the liquid can still be introduced from below; however, in that case the air pipeline would require external power. Which approach is more cost-effective? The former takes advantage of potential energy.
