What would you think of building a waterfall that flows gently along your wall(s)? Without any added compound, just water that traps the dust away. Somewhere, say in calm pools close to the receiving pool at the wall's bottom, you let the dust sediment if it's gross enough to do it quickly, or you filter the dust, and you reinject the water at the wall's top.
The waterfall walls I saw were reasonably silent. They make the air damper and cooler, which is an advantage or a drawback depending on where you work.
Rotating disks do a similar job, draw less power and are more silent, but you may need big ones. Illustration, though or a different purpose, therehttps://www.chemicalforums.com/index.php?topic=57335.msg299467#msg299467
for the atmosphere, you don't need a shell. Built smaller, the thing is sold against tobacco smoke.
Other processes exist. For instance at coal power plants, fumes are extracted by electrostatic filters.
And of course, you can use a fume hood, but they may well be too small, too noisy, and too quickly blocked.
