Function and advantage of wedge wire resin trap screen and strainers

2021-05-13 By zhaozhao

When the resin is used for on-line water treatment, when the water pressure disturbance is large (especially the high-pressure disturbance) and the resin cylinder wall is damaged, the resin will enter the whole water system, which will affect the normal operation of other equipment in the system, so resin trap needs to be installed.
Resin trapper is mainly to install a filter screen with a much smaller aperture than resin on the water system pipeline near the outlet of the ion exchanger and other equipment equipped with resin and has the function of flushing. When the resin passes by, it can be intercepted and captured by the filter screen. At the same time, it can be flushed automatically through the front and rear differential pressure to discharge the captured resin out of the system.
We usually choose a wedge wire screen for this screen.

– Prevent expensive ion exchange resin loss
– Protect pumps and important downstream equipment
– V-shaped wire structure is not easy to block, easy to clean(better than -woven mesh filter element and sintered filter element)
– Large opening area and low pressure(large flow, reduce energy loss)
– Special V-shaped wire structure of wedge wire screen. Uniform gap, no resin leakage, no material running
– The branch pipe bears a large pressure without liner
– Various structures to meet the requirements of different containers

Resin traps can protect downstream filters, but due to the limitation of filtration accuracy, they cannot replace downstream filter cartridges, bag filters, membrane filters, etc.
