wet scrubber


I am setting up a factory for making vacuum-formed acrylic shower bases reinforced with fiberglass. I will be dealing with resin fumes, microscopic glass fibers (from cutting and handling the fiberglass batts) and larger dust particles of acrylic, fiberglass and cured resin from cutting off the bottoms of these units. I am in China, and the factoryies I have seen merely have fans and blow the stuff outside, with some directing the dusty air over a bit of water that supposedly collects the dust. Being from Canada I cannot accept such a poor solution, but my newly hired employee seems to think that the concept is best. I will be looking into cyclone systems, of which a few posts are made on this site, but can anyone post a fairly simple instructable on how to make a water based system for collecting the dust?

Some chemical engineers have had a conversation about how to do some of the things you're trying to accomplish...

That thread should give you a good place to start with some terms to google. You'll need to design your system according to your specific gasses/particulates, so it seems like some assaying and testing are in order...

Good luck,

water collection systems are actually pretty standard for particulate collection. you basically have a tub/vat of water then you pump the dirty air in one end and let the "clean" air go out the other side. works sort of like those end of the hose lent traps for clothes dryers. those typically pump the dirty air in through the top and then let the air vent back out through the top that way gravity and the force of the air forces the particles into the water.

of course after that you'd have to have a secondary process to remove the particulate from the water.


if you can come up with a cyclonic method, then cleaning out the "dust" from the unit would be easier as you wouldn't have to have the secondary cleaning step to separate the water from the funk
