Small Question About Compressing Air in a Storage Tank

[MechEng2020]

Hello all,

I am new to this forum, and I have been searching for some assistance. I am currently working on designing a semi-portable misting system with a group of other Engineering students. We have hit one roadblock, in that some people in the group want to attempt to use a pump to get the water from the tank through the pipes, while I think we should focus on compressing the air in the tank.

My question is, would the compression system be viable? My only concern with the pump option is not acquiring enough pressure in the tubing system to produce a fine enough mist (~60-100 PSI). Any suggestions or comments would be greatly appreciated as I want to continue the design process but need to establish a rock-solid parts requirement first.

For what it's worth, we have access to a 48V power supply for whichever decision we decide to go with.

Thank you for your time and assistance.

It's kind of strange system in your design, i.e. a tank with pump or compressor for a "misting" system, the power system of 48V.

first, the pump is for the liquid application, not the misting system. Normally, the tank is designed for low pressure application, said 5 psig, but not for 60 psig system. You may use compressed air to push the liquid out from the pressure vessel, but not the tank.

Is it a mist generator what's you are looking for?

Define "viable".

Do you mean cost effective or physically possible?

For what you want to do I suspect it is not really viable but depends on the volume, weight and flow.

In most places anything above 15 psi becomes a pressure vessel and a whole host of rules and regulations kick in.

But if you want a portable power source then presurising the vessel before leaving home could be useful e.g. like an aerosol can.

But in most circumstances a portable pump would be better.
