Stainless steel rashing rings serve diverse purposes, and our company excels in their production, utilizing ready-made molds across a range of sizes. Deployed in cooling towers and heat exchange cooling columns, these rings enhance gas contact surfaces while preventing the filtration of solid materials. The pressure exerted by rashing rings aids in the separation of fluids in various processes.
In cylindrical columns where heat transfer occurs, solid tower fillings, namely rashing rings, are strategically employed. The liquid, dispensed with the aid of a liquid distributor, evenly wets the surface of the rashing fillings in an optimal process. Rich gas flows beneath the rashing fill, moving upward through the gaps in the opposite direction of the liquid flow. This design facilitates a larger surface area between fluid and gas, ensuring closer contact between phases.
The dissolved gas in the rich gas is absorbed by the incoming fresh liquid, and the diluted gas is separated from the top. As the liquid descends from the bottom of the column, it becomes enriched through the dissolving process. The concentrated liquid exits the bottom through the liquid outlet. Various types of packed towers exist, with the Rashing Fill Rule categorized as random (randomly poured) and stacked (hand-filled) types. Larger sizes typically utilize units ranging from ¼ inch to 2 inches, while smaller columns often employ the random filling approach.
