Systems are 50 – 100,000 cfm
Systems are fabricated from PVC, polypropylene, fiberglass overlaid PVC, 316 and 304 stainless steel, and mild steel. Capacities are up to 100,000 cfm. Tri-Mer Corporation holds the U.S. Patent #3,616,604 for and has manufactured Fan/ Separator fume scrubbers since 1966.
The scrubbing liquid wets the contaminant as it enters the fan, which allows it to be centrifugally spun out of the fan scroll through a process of dynamic mixing. The centrifugal action, using the fan wheel as part of the scrubbing process, eliminates approximately 55 percent of all air stream 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 percent removal efficiency of 20 micron and larger liquid droplets under a continuous duty load. The scrubber contains a Venturi evacuation drain for continuous removal of scrubbing liquor. The Fan / Separator is a dry-sump system and will contain only residual liquid passing through the scrubber during any phase of operation.
This Specification defines the design requirements, the quality and types of workmanship and materials, and the performance standards and guarantees for equipment, materials and services supplied by Tri-Mer Corporation.
