A Scrubber Fume Disposal System for Arc-Plasma-Jet Testing

摘要

A design of a fume scrubber using readily-available components is described, which is useful in channeling and disposing of toxic or nuisance gases arising in the course of flame testing. A cool exhaust is produced, and is under pressure to permit forced venting to the exterior. No moving mechanical parts are employed and corrosionresistance to permit use of a wide variety of media is easily achieved. An unforeseen benefit is the reduction in noise level resulting from the use of the device, and the scrubber has been found to be of value as an acoustic muffler even in cases where exhaust heat and toxicity are not a problem. Operating characteristics with a variety of media are given. Construction notes are presented for a proposed afterscrubber for gases and various neutralizing tanks for liquids which could be placed in series with the present device if still greater scrubbing effect is desired.
