Abstract:
1. A separator for a mist collection system comprising: a) a cylindrical tube provided with inlet and exit openings to allow air to be drawn therethrough, b) a set of stationary vanes connected in the upstream portion of the tube and sized and positioned to direct the air flowing therethrough in a cyclonic path through the tube such that mist in the air therein migrates outwardly to and in the downstream direction along the inside wall of the tube, c) an annular collection chamber defined in the downstream end of the tube and having an annular upstream opening coincident with the inside wall of the tube such that liquid flowing along the inside of the tube toward the downstream end thereof flows directly into the collection chamber, d) an annular flow restrictor positioned at the upstream opening of the collection chamber and sized for free flow of liquid along the inside wall of the tube into the chamber and for blocking back-flow out of the chamber, the flow restrictor being further sized to provide radial clearance with the inside cylindrical wall of the tube of between approximately one-fourth (¼) to one-half (½) inch, e) a drain hole positioned near the downstream end of the collection chamber, and f) a flow interrupter projecting into the collection chamber to direct the liquid therein into the drain.
