Sieve plates made from SS mesh
I hate drilling holes
Can SS mesh be used for sieve plates

Re: Sieve plates made from SS mesh
My initial thought was NO, I was thinking of an entire mesh plate. Then started thinking of different ways to incorporate very fine mesh into a copper plate.....the more I think the more I think maybe.

Re: Sieve plates made from SS mesh
My thoughts go back to the 5-10% open plate thinking . Looking at the mesh I'm seeing way more than that which would equate to plate colapse .
But surely this is all about surface tension of the stuff on the plate . Tiny holes could overcome surface tension but then there must be a critical size where larger sizes won't cause colapse at power levels that won't cause entranment... but , too fine a hole size causing restiction to vapour flow and bubble production .
Still seeing a need for downcomers
Perhaps there is a compromise where areas of a plate have mesh ... like a coarse hole pattern covered in mesh .
Googe where are you
An excellent question Shady and if anyone can crack it , it will probably be you

Re: Sieve plates made from SS mesh
I'll get started with my latest fiasco sorry I meant experiment, just as soon as UPS drops off some mesh like this

Figure to try it with and without a downcomer

Something I just thought about
It would be easy to plug up fine mesh

Re: Sieve plates made from SS mesh
Don't know if this is going to work but
I've got the plate made and the boiler is heating up.

Re: Sieve plates made from SS mesh
The plate above flooded. Maybe the #100 screen was too fine. I'll try using #40 next time.
Until then I figured to add a downcomer and see what happens.
Note to the plastic police. The silicone is for experiments only

Re: Sieve plates made from SS mesh
First thing I found out
For mechanical reasons, the screen needed to be on top of the copper frame
The screen sieve plate actually worked, but not very good, there was almost more pressure drop across the screen than the downcomer could overcome. In order to get the plate to work, I had to flood it, then turn the power down low for a couple seconds and let the liquid flush down to fill the downcomer cup. Any attempt to turn the power up, would cause the cup to boil/blow dry.
Long story short
The plate had a very narrow window that it would operate over.
And couldn't handle very much power.

Re: Sieve plates made from SS mesh
Interesting. Larger mesh hole size then maybe?

Re: Sieve plates made from SS mesh
not sure how big the holes are in a #40, FWIW, my experiments with holes indicates 1.5-1.8mm works with reasonable power handing.yakattack wrote:Interesting. Larger mesh hole size then maybe?

Re: Sieve plates made from SS mesh
The #40 screen will have the same specs as this

And here's the specs on the #100 that I tried and failed with, probably because it was too restrictive

Re: Sieve plates made from SS mesh
Love that you're doing this shady. How much is this little experiment running you? Also if you do find one that works well how do you plan to fix the plates without using silicone?
How difficult was it to attach and secure the downcomer ?

Spend more time than money
I can't explain it, but I got a picture in my head and it "should" be easyyakattack wrote:Also if you do find one that works well how do you plan to fix the plates without using silicone?
I'm lazy, I reused the downcomer and copper plate from an earlier experiment.yakattack wrote:How difficult was it to attach and secure the downcomer ?
All I had to do was cut out a big hole in the old plate and cover it with SS screen

Look at the prepuched metal from this place. http://www.mcnichols.com/gallery/product-photos" onclick="window.open(this.href);return false;" rel="nofollow
They sent me a packet of samples once. one foot sq sheets of SS punch to dif percentages.
Also, StillDragon sells SS filter plates you could add a down comer to.

shady, do you have a metal supermarkets near you? (it's a franchise that sells small quantity of metals) that mesh on the site you linked looks crazy expensive.

Re: Sieve plates made from SS mesh
have you considered using this application for dual flow plates shady?, no downcomer, match the open area to rising vapors. I've done it with my flap plates, can't see why it wouldn't work thus way. Dads link has some awesome designs!.

Re: Sieve plates made from SS mesh
What I'm hoping is SS mesh can be used as a dual flow plate.
Or if not, add a down comer and find the mesh size that works
The crazy part of this experiment is, I don't need a sieve plate
A friend wanted to know why, there's no info about using SS screen for a plate
I figured to find out why and/or how

Re: Sieve plates made from SS mesh
I tried making a dual flow plate using the #40 SS mesh and it flooded
I ran the plate again with a down comer and it worked
Figure it's time to try using #30 mesh and see what happens.

Re: Sieve plates made from SS mesh
Here's the findings
#100 screen flooded with and without a downcomer.
#40 screen flooded without a downcomer and worked poorly with a downcmoer
#30 screen was too porous and drained too fast to even hold liquid.
I believe it's safe to say, trying to make a Sieve plate from SS mesh, is a waste of time.

Re: Sieve plates made from SS mesh
plates with high % opening are only used for thick material distillation (slurry). There are called 2 way plates if I recall, because they let the distillate run down though the plate.
Otherwise they are inneficient.

The SS screen has been contaminated during a nickel-- iron battery experiment.
