Bubbler design

Postby ThePaterPiper » Sat Oct 07, 2017 11:08 pm

Hi lads and lassies,

Just wanted to run an idea I have been thinking about for a while now by you. Firstly let me warn you that you are about to be blown away by my impressive paint skills, but I digress.

anyway, basically, I am thinking about bubble caps, and how can we get more bubble out of a single bubble cap. So I was thinking of angled sides, like a flat topped cone, with the downcomer in the centre. Cue impressive drawing...

Image


I guess the idea being the vapour has more area to escape on the horizontal plane, and it will push against the liquid that is falling toward the outer edge and making it's way toward the middle of the bubbler.

All based off a 4 inch glasser.

Thoughts?

Ok, so it could be my mental state, or your exceedingly complicated drawings... but which bit is the bubble cap? The small orange bit or the large blue bit?!?! :obscene-drinkingdrunk:

The cap is the orange thing with black slots and the blue is the reflux, I believe.

I can't see why it wouldn't work, would it work better? Not sure, only one way to find out. There's a bit of work there with building cones but I'd be keen to see it :handgestures-thumbupleft:

There is no need to over-complicate the cap design, slanted sides will work the same as vertical sides, but involve a lot more work.

If you think about it the gas will escape the moment it can, this means it will come out the top of the slot, not so much the bottom.
This will push the liquid to the sides of the module anyway.

The reflux difuser is a good idea tho with a centre cap tho.

Yeah, the orange is copper, the blue liquid and white vapor. I see what you mean scyth, I wonder if the slots were different lengths to distribute the bubbles to different radiuii.

I know the cones will be more difficult, but I was thinking they would look really cool. I was thinking of making a die and pressing them, would that work?

It is way over complicated but that’s what the mess in my head translates to :))

If slots were different lengths the bubbles would just come out the bigger slots because that is the easiest path for them.

Pressing them out of flat plate would be easier than forming bending them.
It would be different to look at and if that is what you want go for it.

Well that would be enough lol. I was thinking of flattening. Out some pipe and pressing that. If gas flow were high enough, wouldn’t you get the bubbles coming from the full length of the cuts regardless? There would be a point that the longer / higher portion of the cuts couldn’t cope with volume of gas?

Yeah that would happen, not sure at what power level it would happen tho.
Would be fine on a strip run.
Would it make spirit runs harder?
Would you not get enough distillation cycles to acheive high %ABV?

Yeah, I have no idea mate. It might look cool though. Like a wee Scottish space ship :laughing-rolling:

What about if you had the caps angled inwards towards the bottom and wide at the top? That may give you the little bit of extra resistance and distance through liquid you are looking for?

Side note, you should totally run classes on using paint. You are all over that stuff! :D

Yeah bluc, it is. Just thought with the taper, it would spread the bubbles over a wider series of radii. Smaller bubbles over a larger area, without drilling a million holes for a perf. plate. Plus, looking for something different visually too.

Psyka, that's an interesting idea, but I wonder if that would make the bubbles re-join? Not sure. Thanks for the recognition on my paint skills though! It is rarely recognised. :laughing-rolling:

I have no still building qualifications whatsoever so this is a completely uneducated thought but, wouldn't thinner slots and more of them give you more bubbles than fancy shapes?

Also how much of the bubble cap will be visible once the plates are loaded and bubbling like mad?

Cheers,
Prof. Green.

Functionally I can't see how it would be any different to just running a cap the same size as the OD of your cone cap... 2.5" in a 4" would be about it.

It would look kinda cool, yes, but a whole lot more work involved.

Yeah, good points Prof. Green, they would completely disappear wouldn't they. and yes, I was aiming to find the thinnest cutting tool I could find for that very reason.

Thanks for the advice re size Zac, I was still pondering that. The work, I don't mind so much as long as I can come up with something that is functional and looks cool. It would be a bit sad to lose sight of them in operation though. That may be the deal breaker.

Never mind these blokes mate. You have a novel idea that will work so go for it. Just be sure and post photos. Whether it will work better is neither here nor there. Have a look at Gas ons plate design quirks from a few years ago.

Thanks Bushy. That’s one crazy spider thingy isn’t it! And yes, I think it’s possibly as much about expressing yourself as long as it works. I found some artist copper sheets at the scrappy today, thin enough it will be workable. These bits won’t need any strength, so I think they will be just fine. Anyone used it before?

To me they're just a different shaped cap (except the internal downcomer thingy) so I would still run with 1mm wide slot every 5mm. I don't think you would have to make them any thinner or longer :think:
