Anti-Splash Mechanism for Pressure Vessels

One possibility (among others) would be a perforated plate arranged above the splash zone but below any exit nozzles.

Hi!

Guid me to the design literature please.

Not quite sure what you mean,

One way we do it, on milk vats to keep it from foaming, is on the inlet, we have a tube with a elbow that channels it to the inside wall of the tank, the product comes exits the tube gently contacts the wall and then the product follows the wall down to the level.

Hi!

To be more specific, I am asked to contain the liquid level within the specified limits in pressure vessel. please guide me to the design literature for this problem.

So, this is really about level control in a vessel?

The easiest way to get accurate level control is to introduce overflow weirs into the vessel.

Hi!

U realy got the point, so please send me some standard practices.

Thanx.

The easiest way to deal with this is to check out materials from steam boiler manufacturers and their water level / low water cut-off controls. These can be installed in parallel with a pressure-rated liquid level site glass (a vertical glass tube contained in a pressure-rated housing) so you can observe the liquid levels as well as control them.

The level control will keep a valve open to fill the pressure vessel to the required level, and then shut the valve when the level is reached. Additional switches are available to open a drain valve at over-flow level and to sound an alarm if the liquid level falls below some pre-defined lower limit.

I'm not sure if there really is any design literature on this, other than adapting designs from earlier vessels built in the manufacturer's past. A sketch of the proposed vessel woud help, with all inlets and outlets shown; and pressure, temperature, and fluid specified.

Try a dip tube and a level transmitter controlling inlet valves to stop the inflow of material. The dip tube should address your splashing problem; the level control your... level control issue.

There are many differeent designs that will work, Splash plate, Defusser, baffle, spreader bar, deflector plate, ect. E-mail me at Processes Unlimited Int. Inc. rflaurin@prou.com and I will send you a PDF example. I will need to know the carteristics are and at what pressure your liquid is entering the vessle in order to determine the best sugestion
