Screen Nozzle
Screen nozzle are typically used in media retention vessels where specific flow and backwash rates are desired. Our applications engineers can recommend the number of nozzles needed for effective collection and distribution.
Down-flow reactors can place extremely high loading on the media retention screens at the bottom of the vessel. In some cases, this can require a false bottom to carry the load. Obviously, some provision must be made for the process flow to pass through this plate. This can most easily and effectively be done by installing a number of screen nozzles uniformly across the plate.
They are economical, easily installed, and have several distinct design advantages:
- Type 316L stainless steel construction.
- Continuous slot design provides increased open area for better collection.
- Standard nozzles are 2in./51mm diameter and can be attached to the plate either with threaded end fittings or with “L”bolts.
- Standard slot opening is typically range between 0.006”(0.15mm), and 0.020in./0.50mm wide suitable for 40 to 50 mesh size media, Other slot sizes are also available.
- Wedge wire screen is highly resistant to plugging.
- Choice of either 3/4” NPT or 1” NPT fittings are available from stock. Other styles, such as tee-bolt mountings, and drop tubes are readily available.
- Less expensive than other screen of equal efficiency.
Small systems may be built modularly from off-the-shelf components requiring minimal customization.
