Hello everybody, my name is Ed Miselli. I'm a member of the the oxy kit and pillar tribe and we are building an oxygen concentrated water. Today I'm going to show you how it works, what the parts do and try to explain some of the theory. So let me show you what's going on here. This is our concentrated, this is the one that works really well. So we have a compressor. This compressor is about a two horsepower compressor. How much we actually needed to get 15 liters per minute output. It is quite a bit of you know empty compressor. The air comes the the pressure hazard. We're running around 30 psi at the moment with this compressor so that the air comes out of the compressor and goes into the cooling coils. This is a very simple effective way of cooling the air. I believe it's about 25 foot of copper coil. So you can actually feel the difference of the hot air on the top and as the coil at the bottom. So the air comes directly from the compressor into the cooling coils. After the cooling coils it actually goes into the input pressure regulator. This is set at around 30 psi maximum. So after the input pressure regulator it splits and it goes into these two valves. Those two valves are three port two way valves. So the input comes from one side and this is the per exhaust. So this valve is going to switch from either getting pressurized air or from emptying through this opening. We have two cents each one filled with about about three pounds of zeolite. We're using three inch pipe and I have other videos showing the details of the inside of each sieve canister the details of the the screens that are holding the zeolite in, the springs that are keeping it compressed and so forth. So air comes in from the bottom. It goes through the zeolite. The zeolite is the nitrogen and then then concentrated oxygen goes out from the top. When it goes out from the top as you can see it goes into this this this teethe and it splits off. It splits off into a as you can see here. So we have this y configuration with with orifices inside. Each of these orifices has a 1.6 millimeter diameter hole in it. I made those using aluminum rod drilled in the center with a 1.5 1.6 millimeter drill bit and then I cleaned them up a little bit. What this effectively does is it splits off the concentrated oxygen comes comes out of the active sieve and it's split. Half of it goes into the surge tank. This is our surge tank and half of it goes into the the sieve that's being purged at the moment. And so what this does is the oxygen pushes out the remaining nitrogen in that sieve because now it's under low pressure and it pushes out the nitrogen and it fills this the empty sieve with oxygen. During the next cycle whenever this sieve starts to pressurize it it now has has some concentrated oxygen in there and it actually gets enriched even more. So that increases our concentration and then it feeds again as it comes out it splits half of it goes into the surge tank to be consumed. The other half goes into the the empty sieve to fill it to push out the nitrogen and to to enrich in which it even even even higher than it was when it came out of the first the first sieve. This is our equalization valve. What this does is after the sieve is is purged this opens up a little bit to allow the full canister to start to pressurize the empty canister. This way we're utilizing that pressurized oxygen to fill the canister to to ramp up the pressure quicker. This helps this helps with with the nitrogen and sorption because the higher the pressure the more nitrogen absorbed. The output goes into a surge tank. The surge tank is basically an empty canister that is supposed to temporary hold the the oxygen before it's consumed. The output of the surge tank goes into the second pressure regulator. This is a low pressure regulator set at around seven or eight psi. The output from this pressure regulator then goes into our output flow meter. This output flow meter is set to 15 LPM and then the output from the flow meter comes out. It's split here. One side goes into our mask. The other side is going into our sensor. Our oxygen meter. This is what's going to tell us if it's actually making oxygen or not. This flow meter is set to about 300 milliliters per minute because the flow meter doesn't require very much flow in order to measure it. It's actually, as you can see the label, it's the milliliters maximum. Now I'm going to go ahead and turn it on. The electronics, the impact button electronics, we're using an Arduino board to control the timing. The Arduino board is very simple, very easy to use, very cheap and it's very easy to get. The Arduino board controls a relay board. This is an eight relay board. We're only using three of them actually. One of them is used for turning on the compressor but it's not used right now. Basically, we're only using three of them because we have three valves, equalization valves and two impact valves. So we are going to make the code available. We're using about a five second cycle for each active sieve and a 300 milliliters per second equalization cycle along with a 300 milliliters per second, I guess, field cycle. I'm going to go into the compressor and this will get it going. We're also using a cooling fan next to the compressor. This fan keeps it cool because after several hours of running, the pressure is rising up. You can see from the pressure gauges how it shares pressure rises and minute entry. I first think it's holding Tianra. The tank蓄 propri Gravity okay Allowation So the output of the pole meter is a pole meter. So the pole meter is putting out, going to the two sides of the pole. And then the pole is flat. And the pole is going to go into our, and we go to my pole meter. And we will make you 95.9 with an active wave. And this is pretty cool, I can't see.
