在填充床洗涤塔,洗涤液体distributed over packing material in a column or vessel, creating a thin film of liquid on the packing. As the gas to be scrubbed passes upward through the packing material, it contacts the liquid film providing an opportunity for cooling and condensation or a chemical reaction between the scrubbing liquid and the process gas. Packed bed scrubbers can vary widely in design and can be used in vertical or horizontal gas flow arrangements. They can be used for multiple scrubbing applications and are particularly well suited for acids, inorganic gases, soluble gases, fume control, VOCs, and odor control, among other applications.

BETE spray nozzles can evenly distribute scrubbing fluids over the packed beds to ensure even run-down through the packing and avoid any gas bypass through the scrubber. The ability to provide wide coverage areas from a single point allows spray nozzles to provide simpler piping designs and greater clog resistance over pan, trough, or tray distributors. The ability of spray nozzles to provide a wide variety of spray patterns and be manufactured in almost any material allows them to be selected or custom designed for almost any packed bed scrubber application.
