The Ring Jet™ Technology — Simple, cost-effective, and efficient. The Ring Jet Scrubber technology employs a multistage process that systematically captures and eliminates specific pollutants as they move through the system. The traditional venturi loses a lot of efficiency in the recovery stage of the venturi and does not maximize the removal of hazardous air pollutants. The Ring Jet is a medium gas side pressure drop system that provides maximum removal efficiency with lower fan horsepower than a conventional high-energy unit. With the Ring Jets, the amount of flue gas is limited, by design, to the volume that the Ring Jet can handle at its maximum efficiency. Thereby the downstream recovery zone is shaped to accommodate the flow of flue gas and water droplets and minimize pressure drop. Particulate removal is achieved at the lowest pressure drop. Maximum removal of acid gases and submicron particulate and aerosols is achieved through the following modifications to an existing scrubber: The Packed Bed Stage: Flue gas entering from the quench stage of the existing venturi passes upward through the scrubber‘s packed bed and liquid is sprayed onto the packing to remove heat from the flue gas. As heat is removed, flue gas water vaporizes into liquid droplets that "capture" particulates out of the flue gases. The cooled and preconditioned flue gases then move to the next stage. The Ring Jet Stage: This stage is comprised of an assembly of many Ring Jet venturi units located on a separate floor of the scrubber tower. As gas enters the Ring Jet, the flue gases pass a manifold of ring jets that subdivide the gas stream in order to boost separation and efficiency. Water is symmetrically injected at a right angle to the gas flow. The high relative velocity differential between the liquid and the flue gas force particulates into liquid droplets. Aerosols and submicron dust particles generated in the cooling and absorption stage are collected here. The Demister Stage: Designed with two demisters, this stage will recover greater than 99% of all droplets contained in the gas that are 10 micron or larger. A seal pot prevents gas from bypassing the demisters and any remaining liquid captured in the demister is returned to the Ring Jet Stage for further capture.
