Hello Forum Members. I am cautiously moving forward in anticipation of recovering my values from 20 years+ accumulation of jewelers bench filings. They are clean. I sort of incinerated them, more of a pyrolysis actually since I did not leave my burnout oven door ajar so not enough oxygen. I am preparing to finish the process in a stainless steel frying pan.
This Forum is really great to work with. The Library is excellent. Everything I need is right there. I should have gone there first before I incinerated. Harold has an excellent post on incineration. Of course I was just randomly reading posts at that point. I am working from 4metals designs on putting together a scrubber. It will be overkill and work with a semi closed reactor in the fume hood which leads me to my question:
I am thinking of constructing a small fume hood from a plexiglass aquarium. I got the idea from a post on page 7 of my favorite go to place right here, Build your own Equipment. It is the last post of a short thread called Fume Hood Ideas. It is a youttube video of a plexiglass put together. I like the idea for visibility and light. I will be in the garage. Until then I was tending toward the 55 gal plastic drum as the shell, for containment reasons and simplicity. The plexiglass aquarium I am looking at is 20 gallon, 30" x 12" x 12" (small) if I can find one a little bigger in height like 18 inches it would be better. Would any of you go this direction or a plexiglass cabinet like they use for sandblasting? With a small plexiglass fume hood I will have the visibility and can probably vent the entire enclosure through the scrubber (two 5 gallon H2O2 bucket/chambers and third column 12 inch diameter 6 foot tall that will actively flow caustic over two packed chambers. I will be working with 1000ml Berzelius Beakers for one to three ounce digestions of filings. The 55 gal drum will probably be too big to vent through the scrubber so smaller is better. I am kind of answering my question while I am typing. Maybe I should just get a smaller drum and light it with the pyrex pie plate insert. I don't know. I have 38 ounces to process and then I am out of business so this equipment does not have to last more than that. Please let me know your thoughts.
Many Thanks in advance,
Tom
