advice on fume scrubber _fumescrubber_

[gregory-d]

get the 1" size, it will give you more CFM.

Cool thanks.

Easy enough to put a vacuum guage on it, like I said this will be the most important piece of equipment I will ever have, safety first, the other thing I am studying at the moment is safely dealing with the waste, when I am confident of that only then will I start refining

delboy9891, I could suggest a vacuum valve, you need a vacuum however a slight reduction in vacuum may slow the velocity of the fume going through your system. In my situation, we are installing Column Scrubbers with Glass Barrel media to slow down and diffuse the fume.

you can neutralize any waste to pH of 7

Yes after having dropped most of the Hydroxides.

Those are nice columns, how tall are they? As suggested a vacuum valve to slow down the airflow to better match the flow generated by the eductor with the size of the column. Remember the retention time for the fume in the column is what makes this work. And all glass gives the advantage of seeing the color of the fume to determine when you need new chemistry.

Glassware is where it's at. It can be done a lot of ways once you have the basic assembly. Everything begins small, as you find success growth begins in the size of your capabilities. I deal with ores exclusively, I'm no longer dealing with refining as it's too competitive to get the gold to refine.
All ores must start with Pre-treatment, no pre-treatment and you'll never see the gold. He's a few basic starters in Pre-treatment roasts, but there are many others. Breaking complexes is what I do. There isn't any New Chemistry, what I do is apply different applications to existing technology. No Hocus-Pocus, just analytical chemistry.

If you need any more info, just ask...

Hi Peter, could you please provide some information on the eductor you are using with that pump in the video please. I am in the process of setting up a scrubber and love the simplicity of yours. I have a pump on the way with very similar specs to the one you have used. Im thinking of ordering one of these https://www.spaparts.com.au/waterway-gunite-venturi-jet-with-extension-nozzle im just not sure if the 40mm pipe size will matter! i am also going to purchase some variations in the nozzle sizes. 1/4, 5/16 and 7/16.
I look forward to hearing from you soon.
Regards
Geoff

Welcome

Welcome

Thank you, i have hung around here for quite some time and read lots of really interesting and insightful things. I have just never felt like i had done enough reading to post questions.

 

[geoffrod]

So i have dug around the Web and found comprehensive tutorial on building the water aspirated vacuum pump, found here https://www.tetragrowth.solutions/b...-aspirator-vacuum-pump/circulating-water-pump, also there was another which even has 3d print files for the aspirator/eductor https://pubs.acs.org/doi/full/10.1021/acs.jchemed.9b01123.

I have been under the understanding that washing gas through solution is washing. primarily to distill and recover the acids.
I built a washing station and what thought was a scrubber which involves activated charcoal so that clean air can be vented into the atmosphere.

For the most part finding gold in nature and the chemistry of precious metal extraction is a game. Chemistry is a: You get what you put in discipline. I don't neutralize my acids I get them back and reuse them. Why use money to buy more chemicals if I already have the chemicals in solution.
My rules are get the gold for free, process it conservatively ($) and maximize profits.

I can do in 2 weeks what others can do in 1 hard fought expensive day.

In any case this is a cool conversation and the examples are great!

I'll need to review my terminology because I'm no longer confident I'm using the correct terms.

i got some of these to go in the scrubber i am building! are they ok? i havent seen anyone using ceramic rings, i also got some bio balls as well

Yes, I'm curious if those would work as well.

 

[geoffrod]

they work, perlite too. It's best to get #3 or larger though and you'll need to do some research on humidity. Too dry with those and the absorption will not be good. Eventually the fumes will create enough moisture, so it'll work out sooner or later.
Have you considered activated charcoal? there's theres good reason for it's fame.

You can make it yourself, but you need a metal drum with a lid or something. It's pretty much a product of incomplete combustion. It's WAYYYYYY better to just buy some. In part because the danger with incomplete combustion is that when everything gets right, it goes boom! Some people just burn wood and use the leftovers but that not efficient and it's also not activated charcoal, it's mostly just unburned wood so you don't get those benefits.

A benefit of a good activated charcoal system is that in theory, obviously not in practice one could vent the fumes right in thier face and breath easy. That would be incredibly stupid but that's how well it works, done right.

For extraction I truly believe DIY is best if you know how to make stuff and do electrical and such. because for the money anyone with those skills can outbuild any commercially available system. I'm a true believer in overbuilt extraction systems.

Thanks for the reply,
Im not sure i understand about the humidity, these will be sitting in a tube filled to 90% volume with sodium carbonate solution or Sodium Hydroxide.
Have i miss interpreted what you where saying?

I'll just toss this out there for those who like to mess around.
I know how to get my chemicals back, currently, I'm recycling my fumes during my reactions, mostly, and that's cool.
I figured out that it's pretty easy to set up a jig that gets your HNO3 out of the flowing extractor. Why? I just can't help myself, Why not?. I don't like Why?

The thing is I won't have to do setting up, DIY beaker covers, cleaning, leaks, teflon tape, concentrated sulfuric acid. Just work pumping tunes and fa la la, Just distill.

I don't have it figured out TOTALLY yet but those woodworking hoses, some 3/4" PEX and a TINY sonic mister. Shoot man!
If your into it, make it better. This will be a gigantic time and money saver for everyone.

OH shoot. Sorry. I totally got in the wrong section. this was for something else. I*'m sorry. I'm going to see if I am able to delete my reply. Again my apologies. Dumb mistake on my part.
