Series 6500 Jet Ejector Venturi ScrubberSeries 6500 Jet Ejector Venturi Scrubber

Overview

The ideal scrubber selection for low to moderate gas volumes when gaseous and or particulate contaminant removal is required.  The Series 6500 Jet Scrubber creates its own draft to eliminate the need for a fan in most cases realizing cost savings and system simplification.   Inherent with this design, gas is scrubbed with no bypass resulting in a scrubber that can be used for large turndowns in gas flows. The Jet scrubber utilizes a high scrubbing liquid to gas ratio also making it the preferred selection for treating high concentration gas streams to reduce the resultant exothermic reaction temperature rise of the scrubbing liquid.

Jet scrubbers are available in single and multiple stages or can be combined with a Series 5000 Packed Bed polishing scrubber afterwards for additional transfer units to meet extremely high gaseous contaminant removal efficiencies.

A wide choice of entrainment separator types; baffle, cyclonic and fiber or chevron blade modules enables the Bionomic Series 6500 Jet Ejector Venturi Scrubber to neatly handle a complete range of pollutants. All separator types can be integrated with scrubbing liquid recycle tanks in capacities and configurations specifically designed to meet a particular application.

How It Works

Jet Venturi How it Works DiagramThe Jet Venturi utilizes a large scrubbing liquid volume (1) introduced through a special high pressure nozzle (2) to aspirate the pollutant laden gas (3) into the chamber (4) in a concurrent flow pattern. As the gas enters the throat section (5) nozzle formed liquid sheets and droplets are sheared and break up into much smaller sizes due to the high relative velocity difference between the gas and liquid. These extremely small droplets create a tremendous amount of surface area for gas absorption and impaction collection of particulate to occur. Due to the even distribution and large volume of liquid throughout the throat cross section gases can be scrubbed even at extremely reduced rates with no appreciable decrease in removal efficiency. The gas with pollutant containing liquid droplets then proceeds out of the throat into the diffuser section (6) where further scrubbing action occurs. Droplets are removed from the cleaned gas in the entrainment separator (7) before the cleaned liquid free gas exits the system (8). The liquid with contaminants drains through the outlet (9).
