building an ozone generator

Guest
I have a 7.5kv transformer from a neon sign and I want to use it to build an
ozone generator. I read somewhere that the best way is to wrap tin foil (or
wire screen) on the inside and outside of a mason jar and connect the leads
to each layer of foil without them touching each other. Since the glass is
acting as an insulator, why couldn't I just get a piece of plate glass and
fix a fine wire mesh screen on either side? What size would be effective or
too big? Is the shape important? Should I have a fan to circulate the air
around it? Thanks in advance.

You are aware that Ozone is toxic, right?

It's also highly beneficial in the correct doseage. An ozone generator
has just been developed that kills the virus that gives rise to cold
sores with one 10 second application of its gas shroud to the affected
skin! Ozone's a terrific disinfectant in general, actually.

It's always helpful if you would kindly disclose what you plan to do
with your ozone generator? Are you trying to replenish the depleted
ozone layer? Purify well water? Destroy all the rubber parts in your
house? Manufacture smog? The design tends to follow the application.

for why you don't want to use an open arc to generate ozone.

Looks like the amateurs are getting into air-zones' panties ;-)

The results of an experiment measuring the effects of ozone in very
low concentrations on the lungs was published a few years ago. If I
am remembering the numbers correctly I think they found a double-digit
percentage decrease in function even at extremely low concentrations.

Google, or a Medline search, could probably turn that up.

For shock ozone treatment an open arc is just fine.






>for why you don't want to use an open arc to generate ozone.
 
Ozone is only "toxic" because it is a very effective oxidizer - probably THE
most effective. It oxidizes everything organic that it touches.

Flat plate ozone generators can work well. Basically you have two flat metal
plates connected to the HV generator and kept apart by an insulating sheet
larger in area than the plates. Mica seems to work the best although glass
can do but it tends to not last as long.
The separation distance is something that you will have to experiment with.
Making one sheet of wire mesh has also been tried as this allows the ozone
to escape more easily. especially if air is blown over it with a fan.
Please note that any HV ozone generator can also produce nitric acid from a
combination of moisture and nitrogen from the air. Apart from the health
risks this will rapidly destroy the metal plates.

....and you think that this fact justifies the quotation marks you
put around the word "toxic"?

Remember Doc Brown from the _Back to the Future_ movies? Do you
have an "impossible" engineering project that only someone like
Doc Brown can solve? My resume is at http://www.guymacon.com/
 
My company makes ozone monitors (and other gas detectors). Frommemory,
the danger levels for ozone start at 0.1ppm - at any rate that's where
the first alarm level is (these things are defined by various safety
bodies, depending on your country, they all more or less agree)

So though a photocopier or laser printer is OK, I wouldn't want to be
near any other source 8)

We sometimes use chlorine to check ozone sensors are working. (Easier to
keep in a bottle or generate: ozone tends to decompose.) You wouldn't
want a lungful of that, would you?

Not THE most effective. It doesn't oxidize xenon, but potassium
fluoroplatinate will.

There is a lot of 'I'm safer than you' zealotry. They often all agree
simply because lower levels of the substance either occur naturally or
can't be reliably detected. AIUI, at 0.1 ppm you can JUST smell ozone,
and if you can't smell it, you won't complain about it.

Apart from the ozone related problems, let me remind you that neon sign
transformer is a bad choice for this application - it is much too powerful
and very dangerous. Such transformers can provide enough current to kill you
instantly, so watch your steps!
