Plate spacing, thickness and Dc's
Posted: Wed Jun 12, 2013 9:44 pm
Hi all,
Sorry for the essay to follow :-B
I'm about to commence my first build with a 4", 5 plate modular perf bubbler with an add on packed section for vodka.
I have all the goodies apart from some 1.6mm flat sheet for plates, a few reducers and a parrot (I cant be bothered building a parrot).
Before I start cutiing I have a number of things I'd like to confirm so I dont have to do things twice !
I have expandon stainless ferrules to solder on over the 4" column with 3" sight glasses.
I will be sitting the perf plates in between the joins of each modular section, to allow for easy cleaning and alingment as well as less soldering which is a bonus.
Now I know that most peope use a 100 - 120mm plate spacing, with the same distance between the boiler and first plate. Will 150mm make a difference? Space with expandon ferrules is limited?
I would assume not if they are all even?
I have a number of copper sheets which are about 0.9mm thick with dimensions of 300x400mm for plates but think I need to go up to 1.6mm. Any advise on minimum plate thickness?
As for DC's, I'm going with 3/4" however I'm a little confused as to whether a 1" inch cup soldered to the plate below is better to obtain a fluid lock (weir system).
I was thinking a DC height above the plate of 20mm, dropping down into a 1" cup (cup soldered to the plate below)
eg: cup 1" diameter and 20mm height soldered onto plate with downcomer "falling" from above, about 10mm into the cup below to form a fluid lock.
Any advantage to this method? or should I simplify the build by dropping the DC to within say 10mm of the plate below and the distilate on the plate forms the fluid lock?
I'm also looking at a 4" diameter by 5 inch refulx condensor with 7 x 3/4" tubes
Also product condensor of 2.5" diameter by 23" long with 4 x 3/4 inch tubes.
Packed section for vodka will be 4"diameter by 6".
Looking at starting this build this weekend so feedback and advise greatly appreciated!
Obviously a build thread will follow ;-)
Cherrs everyone!
