- This is a scaled down version of my wet scrubber invention. I'm testing it to see whether it sprays water everywhere. The water is contained in the bucket, it works.

Do you maybe have a drawing of how it works? I also want to build one but I dont quite understand how it works
Genius
So, what happened next? I've been wondering about this idea off and on for at least 7 years. Seems there are a small handful of videos out there with people who have had the same idea and actually come up with some sort of prototype. Is it actually useable?
Hi Frank,
Thanks for your interest in my project. Yea I haven't touched this for several years since I have been between living situations. In the end, the wet scrubber technology is great for removing particles down to 1-10 micron range but submicron particles (like smoke) will pass through it very easily. My conclusion is I wasn't able to surpass current technology of getting down to submicron filtration using just water. Using just wetscrubbing will either require many many stages and large pressure drops to get to the sub micron range. This means the use an external "flux" is required to get the smaller stuff meaning the particle laden air is either charged with high humidity or with static electricity to be removed with an additional stage.
This is what I tried with the an electrostatic precipitation stage if you look at my other videos. An electrostatic precipitator will remove sub micron particles but at the cost of energy, increase bulk of machine size, and with some ozone generated. If you goto the EPA archives, there are some great info about wetscrubber technology. The best technology I've heard of so far is known as a cloud scrubber which uses the high humidity "flux" technique I mentioned. If that could be miniaturized to something like a household air filter, I think it would be a great invention.
The wetscrubber is still pretty decent as a shop vac, it sucks up lots of dust and filters out most of the particles without having to empty a the vac very often. A hepa fabric filter product will still out perform it however in terms of filtration but will require frequent filter changes in exchange.
Locke Lab that sounds great. I was thinking of it in terms of wood shop dust collection, in line with a cyclone separator. Large or small, but for me personally I currently only have a shop vac with a Dust Deputy and a fancy dust extractor. I was thinking that something like your product would work to practically eliminate that kind of air contaminant completely from ever entering the filler at all, or is that a pipe dream? I got the idea from my very short term ownership of a Rainbow vacuum cleaner.
@@Frankengruvin I have built something like what you are describing. Shopvac with second stage water filtration. Its a bit crude but it works. Check out this video ua-cam.com/video/bS2QPDEt284/v-deo.html
It filters out lots of things but leaves behind the invisible tiny particles that only a hepa could take care of. If you add a third stage then it would make the hepa filter last a lot longer. Downsides of the second stage water filtration is you must remember to empty and sterilize it time to time with bleach, it can get nasty and spew harmful germs.

Is this to remove Sulphur oxides? Or particulate matter?
This is more for larger particles. It would have to be optimized to have higher surface area in order to scrub gases. The scrubbing liquid may also have to be different than plain water to do so as well
