cold vaporization.

[maxopus]

a question (every one comes to me).
with a friend we designed a machine based on a hot vaporization system (of simple water).
The machine works however, being my brain always looking for better solutions, today I came up with something that, if possible, could simplify the system.

I thought about the technology used by pump injectors.

As it is not necessary that the steam is hot (but it is necessary that the water particles are very small) then it could be much simpler, energeticly less expensive and much less bulky to obtain vaporization for high pressure instead of for high temperature.

It would be a much simpler thing than a pump injector in the strict sense, as it should have much less expensive and limited workloads over time simply controlled by a timer.

I also heard about ultrasound vaporizers.

in practice it would be very finely vaporizing 250 cc of water per minute.

Is there any one of you who has experiences or useful news in this sense?

Thank you in advance.

hello max, I take advantage of it to greet you.
I've been curious about this and, looking around, I found this definition.
industrial ultrasound vaporizers work from 20 to 40 khz
but the piezoelectric crystal has an impedance
high, so to get him to deliver 5w... p=v^2/r
i.e. v=sqrt(p*r) if p=5w and r=1mohm the voltage is high.
on this principle work some types of aerosols, try to search on google, "ultrasonic cleaner schematic"then there is this:http://www.ultrasuoni.it/principio.phptry to click on "technique".
if they can help you.. .

If you go to a children's shop or one of appliances, find two types of humidifiers and two types of aircraft.
"classic" (both humidifiers and aerosols, I mean) and ultrasound
In fact these last ones are absolutely cool.
silent, emit a constant and cold steam and immediately ready
I can't get into the detail of the operation, however a small amount of water is maintained over a kind of metal foil that is made to vibrate at high frequency, generating this "steam" which is then diffused with an air flow

those I have at home don't reach those courses, of course.
250 cc maybe in an hour....
but it might be interesting to take it as a point, even if I suspect it is not so simple to make a large enough for your amount of water to vaporize

One thing about the genere?http://www.mainlandmart.com/humidify.htmlhttp://www.siansonic.com/ultrasonicatomizer.htmhttp://www.bosan-control.com/product_detail.php?pid=84&cat_id=18alternatively we should discover the source that infests all our zones of fine water particles suspended in the air, often apostrophes as "killers", like certain curved diabolics:

thanks to all for the info.
I also saw some of these pages.

I will investigate, the ultrasound system seems to be the cheapest to achieve even if reaching powers like those we demand will be almost impossible (or at least it can give big problems of bulk).
keep in mind that the 250 cc/minute are those of the small machine.
then there is the standard machine from 500 cc/minuto and then the big one from 1.000 cc/minuto.

Orpo, in the rush I had not realized that they were /minuto... I knew those links for an application I should do but I was thinking about my needs, 500cc/hour:redface:

I have no idea the costs, but the ultrasound nozzleshttp://www.siansonic.com/pdf/ultrasonic_nozzle.pdfarrive at 2000cc/hour, they are very compact (ø40, h100mm) and with thirty of them, in little place, you get the maximum flow you need. I have no idea even the cost for the generator that will have to feed them but should not be exaggerated and however in line with the corresponding for ultrasound washing machines.
Now that I've done a half a kilo of your caxxis, I'm going back to my parents and I'm going to end up hurting:

I normally do a lot more damage than you.
compared to me in the field of damage you are an amateur.

do not provoke me eh!...otherwise I open a thread on the helical excavation, which is a sort of "end of world" [cit.] :biggrin:

 

[maxopus]

If you know how much they asked me for an ultrasound system... to fall on the ground.

 

[fab69]

Well, let him know no, so we play "all down the ground"! :biggrin:

Cheers. !

[fab69]

However, really there is something to turn into the chair!
Otherwise, did you think about the radiant plate systems with water jet? you should still get the required course. as long as after the generated steam is "manageable" for your application. . .

I thought you had any idea of the orders of magnitude of generator costs with some power.
for this my ultrasound washing machine for years pampering, polishing and trying to never make her sick, even if, when it happens, looking at him in the belly I have every time the impression that these tear us not little...
