The picture below is of the after stage thein I mentioned in the first part of this blog along with an addition.
If I have a bucket of water in the shop, along with my walls eventually getting coated with dust from it seeping out of my poor filter bag on my dust collector the water get filled with dust and it sinks to the bottom. after a few days of heavy wood cutting a 1/4” layer of dust is at the bottom. Yes I know, I need to do something about this. Part of it is my mediocre dust collector and part of it is my need to get it better to my collector from my various tools. But that’s another set of issues.
I mention the water because I had an idea of using it to trap the fine dust. It would be simply a spray of water that the dust has to pass through and hopefully get caught up in the water and wash down into a bucket. The diagram below shows a 1/2” pvc pipe suspended in the center of a 6” a pvc pipe. The whole thing would be hanging in a bucket. In the bucket is a small sump pump that is submersible. It would all be wired together to a plug so that when the dust collector was turned on the pump would run also. The pump would send water up and into the 1/2” pvc pipe. The pipe has multiple small horizontal slits cut in it that would spray water out 360. i.e. the slits wold be cut on the pipe rotating around it. The pipe is capped at the bottom so the water is forced out of the slits.
I’m wondering if by the time the dust and air gets to the bottom of the pipe if it would be trapped by the water and drain into the bucket to be sucked up again and trap more dust.
Another thought would be to make the downward 6” pipe much larger. The air would be slowed considerably and the dust might be caught more easily by the water.
Thanks for your thoughts. It will be at least a year before I might try this as I’m currently very busy but It’s been in the back of my thoughts for awhile now.
