Vessel Internals Custom Design - Wedge Wire Screen

Wiki Article

Vessel internals are basic components for efficient filtration and separation, custom-designed to meet specific pressure and quality requirements. They play an important role in industries such as petrochemicals, pharmaceuticals, refineries, and wastewater treatment.

Among various options, wedge wire screens have emerged as a popular choice for custom-designed vessel internals.

Wedge wire vessel internals evenly distribute gases and liquids for maximum mass transfer in air and water pollution control systems.

Wedge Wire Screens
Wedge wire screens are filtering and screening devices made from V-shaped wire. They are wound into a cylindrical or flat panel shape. The vee wires are welded to supporting rods, creating a continuous slot that is narrow at the top and wider at the bottom. This design offers high strength, durability, and precision filtration capabilities.

Why do we use vessel internals with wedge wire screen
Wedge wire screens offer several benefits that make them an attractive choice for vessel internal design:
▪ High Filtration Efficiency: Unique wedge-wire design allows for high filtration efficiencies, typically exceeding 99%.
▪ Long Service Life: Made of stainless steel 304, 316, and 904L, it is corrosion resistant and can be used in the harshest environments with a long service life.
▪ Low Maintenance: The wedge wire mesh has a self-cleaning function, which is easy to clean and maintain, thus reducing downtime.
▪ Customizable: Custom wedge wire screens allow manufacturers to design slot openings, wire shapes, and configurations that match the specific particle sizes and flow rates required for a given application.

Application Cases of Custom Wedge Wire Screens in Vessel Internals
1. Petrochemical Reactors
In petrochemical plants, wedge wire scallops and support grids retain catalysts while allowing process fluids to flow freely. Custom-designed screens improve flow distribution and ensure uniform catalyst retention, boosting reactor efficiency.
2. Water Treatment Systems
Wedge wire screens act as media retainers in filters or dewatering units in water treatment systems. A custom design allows for precise filtration, preventing clogging and reducing the need for frequent maintenance.
