Case Studies Case StudiesTri-Mer’s Fan / Separator is an all-mechanical fume scrubber. This fume scrubber is widely used for sulfuric acid pickling, metal plating and battery charging operations.
Fan/Separator is a 2-stage fume scrubber that is highly efficient at removing H2SO4 and other contaminants from the airstream.
The scrubbing liquid wets the contaminant as it enters the fan, allowing it to be centrifugally spun out of the fan scroll through dynamic mixing. The centrifugal action, using the fan wheel as part of the scrubbing process, eliminates approximately 55% of all airstream contaminants. Scrubber has dynamic scrubbing as the first stage and impingement as the second stage.
The impingement process causes the air to change direction as it passes across the rigid packing media. The packing media also acts as a mist eliminator section. The packing media is supplied in framed packs and provides 99% removal efficiency of 20 micron and larger liquid droplets under a continuous duty load.
Contaminants enter the eye of the fan where they are treated with a fog mist of scrubbing liquor.
Operates with 20% less brake horsepower than conventional fume eliminators.
The fume scrubber’s high efficiencies are possible due to its unique use of the fan as a centrifuge in the scrubbing process.
Fan velocity is precisely controlled so that air crossing the rigid packed media stays within design parameters. The system is positively pressured, working the reverse of conventional “negative air” scrubbers. Thus, air is pushed, rather than pulled, through the system.
55% of system performance results from contact between the contaminant-laden air and the rigid tube packing; 45% is from the centrifugal action of the fan wheel. The unit is extremely effective in eliminating corrosive contaminants; outlet is near saturation. Total energy consumption is generally 15 to 20% less than comparable wet scrubbers with a negative pressure design.
The Tri-Mer fume scrubber was engineered for simple installation and start-up, so start-up costs are low.
