Wedge wire screen panels are widely used as catalyst support screens and grids for the petrochemical and refining industries. The support grids are manufactured by v type profile wire, and screen slot is narrow in the above and wide in the below. It has characteristic of durable structure, high strength, load capacity, precise open area and non-clogging. Support grids have flat surface and are available to allow installation through a manway.


Basic Principle


The support grid is a removable screen and self supporting filtration structure, which used to retain the active media or catalyst, while allow the gas or liquid to pass through. It can also withstand pressure drop over the catalyst bed during the entire catalyst cycle.


Benefits


V type wire, non-clogging surface

Self supporting

High open area

Accurate separation

Resist high pressures, temperatures and stresses.

304 stainless steel construction, corrosion resistance


Applications


Sand filters

Carbon filters

Lon exchange

Molecular sieves bed support

Other fixed bed catalyst reactors
