Resin trap filter is generally installed at the back end of the negative bed, positive bed, and mixed bed of the ion exchanger. When the quality of the resin is poor and the water pressure disturbance is large (especially high pressure disturbance). When the resin is damaged, the resin will enter the back-end desalted water system and affect the normal operation of other equipment in the system, so a resin trap filter screen needs to be installed. On the water system pipeline near the outlet of equipment containing resin such as ion exchangers, install a resin trap filter screen with a hole diameter much smaller than that of the resin. It also has a flushing function. When the resin passes through, it can be intercepted and captured by the filter screen. At the same time, it is automatically flushed through the front and rear differential pressure to discharge the captured resin out of the system. Resin trap filter is used as a supplementary equipment of the ion exchanger to prevent the trapped resin from leaking into the desalted water system when the water outlet device fails. To ensure the normal operation and use of subsequent equipment. It has small size and high recycling efficiency. Our resin trap filter uses stainless steel wedge wire screen as raw material. The stainless steel trapezoid profile wire filter screen has high capture efficiency, large flow area, good mechanical strength and low pressure.
