Venturi scrubbers, (including ejector venturis and eductor venturis), efficiently remove fine particles from volatile, hazardous or corrosive gas streams, or gas streams containing solid materials that are difficult to handle, particularly if gas streams are under 300°F.
11 Features of a Venturi Scrubber:
- Venturi scrubbers collect coarse or fine particulate, including particulate under 1 micron and particulate that is sticky or high in moisture.
- When there is a high percentage of fine particulate under 1 micron, the pressure drop and energy requirements becomes very large for efficient collection using a venturi. In practical terms, a venturi cannot collect particles smaller than 0.5 micron.
- Venturi scrubbers with a quench section (evaporative cooler) accommodate high temperature gas streams, including those from casting, sintering, glass manufacturing, incineration and pyrolysis.
- Venturi systems are suitable for high dust loadings.
- Venturi scrubbers accommodate variable gas flows.
- Venturi systems are continuously wetted, and are not vulnerable to clogging, plugging, scaling, or wet/dry line build-up.
- Collection efficiency for venturi scrubbers is 95-98.5%, (depending on the number of stages.)
- Slurries that contain high concentrations of solid material, or valuable material, can be recycled.
- A mist eliminator module provides entrainment separation.
- Venturi systems are custom manufactured in capacities to 300,000 cfm.
- Venturi scrubbers accommodate vertical or horizontal scroll outlet.
