Deroy lens improvement

[enrysuper]

Hi,
I bought a Deroy''s lens, also called "Lentille de correction", a sort of dephlegmator, it works in order to "pre-condense" the fewest volatile components, and let goes out the most volatile, due to a "veil of water" placed on the heitght of it.
That is!

The first run with this support disappointed me, because the "weil of water" don't cover all the surface, and ABV doesn't rise, and the feints/head concentration don't improve

So I decide to open the object in order to discover it.
That's is!

So I think that I can put a reverse pyramidal pattern coil in order to condense back into liquid when the vapour comes into contact with the "reflux coil".
(sorry for this picture I don't use CAD but I must learn)

I think I can collect more foreshot/head, because when the flow rise up, the fewest volatile (ethanol-tails mixture) fall down and the most voltatile (a part of methanol, etyl-acetate..) go to the waterjacket then they will be rejected. I will do the same with tails.

Questions are, could it be a right way? Is it an improvement? Suggestions?

Thank a lot
