Negative pressure recoil resin trap filter matched with an ion exchanger.

Why use the BLU-SZB-02 series resin trap filter?

The resin trap is a device installed on the ion exchange water outlet to prevent resin leakage caused by the failure of the water outlet device of the exchanger.

The device can also be used to intercept and crush resin to ensure the safe operation of the boiler system. The device is widely used in power, petrochemical, and other industries.

Due to its structure, the resin trapper in the prior art has the following shortcomings:

  • After the equipment runs for a period of time, the equipment often has to be shut down due to the blockage of resin debris. After shutdown, open the blowdown and manually clean up the captured resin debris.
  • If necessary, the screen tube in the catcher must also be unloaded and the broken resin embedded in the screen tube gap must be cleaned with a steel brush. The above phenomenon is particularly serious and frequent in the resin catcher of the high-speed mixed bed for condensate polishing of subcritical and supercritical generator units.
  • This not only shortens the normal operation time of the equipment and affects the improvement of production efficiency, but also often endangers the safety of the unit equipment, but also increases the labor intensity of the operators.

BLU-SZB-02 series wedge wire screen resin trap filter overcomes the shortcomings of the prior art and provides a negative pressure recoil resin trapper that can clean itself under the condition of uninterrupted operation.

The wedge wire screen filter element has a continuous slotted structure with a uniform gap. The v-wire structure makes it difficult to block and easy to clean.

The advantage of the product is that it can realize self-cleaning of the system without shutdown, overcome the shortcomings of regular shutdown, disassembly, and cleaning in the prior art, improve the safety of equipment operation and prolong the service life of the system.
