Series 6000 Tray Scrubber Systems Series 6000 Tray Scrubber Systems are available for gas flow rates from 1,000 to 150,000 acfm and utilize sieve, valve or bubble cap trays instead of packing to achieve high efficiency gas absorption with extremely low liquid throughput. These scrubber systems have less tendency to foul than countercurrent packed towers due to large diameter tray openings and achieve higher removal efficiency on micron-sized solid particulates than packed towers. The Bionomic Series 6000 Sieve Tray/Bubble Cap Tray Scrubber employs our proprietary Lo-Flo Tray in a perforated sieve or bubble capped riser design. It is capable of scrubbing out both fly ash particulate and hydrochloric acid contaminants. Our tray scrubbers are less susceptible to plugging from particulate in the gas stream than a packed tower design, while offering up to 99% hydrochloric acid removal and fairly high particulate removal. Depending on the removal efficiency needed, the number of tray levels supplied can vary between two and five. Pressure drop ranges from 3 to 11 inches of w.c. for this type of scrubber. During operation, the gas to be cleaned flows vertically upward into the tray section through the sieve holes or capped risers, which can vary up to 1-inch diameter. Scrubbing liquid is introduced to the top tray where it flows in a horizontal cross flow direction to the gas rising over the tray's surface. The gas velocity through the tray openings, holds the liquid up on the tray and creates a froth layer where violent gas and liquid contact occurs to remove particulate and acid gas. After traveling across the tray, the liquid flows over a weir and down to each successive tray level for further scrubbing and contaminant removal. The spent liquid finally cascades into the sump section of the scrubber vessel and discharged on once through water arrangements, or retained in the sump for recirculation and reuse when a chemical reagent scrubbing solution is used. The unique design of the Bionomic Lo-Flo Tray Scrubber enables use of water condensate or other industrial effluent sources to completely eliminate or reduce unit operating cost. If unavailable, sodium or calcium based chemical reagents can be used for the scrubbing liquid.
