Why use BLU-SZB-05 series Resin Trap Filter?

In the water treatment process of cation resin exchanger, when the resin quality is poor (insufficient strength), the water pressure disturbance is large (especially high-pressure disturbance) and the resin cylinder wall is damaged, the resin will enter the whole water system, affecting the normal operation of other equipment of the system.

Therefore, it is necessary to install a resin capture device.

The resin capture device is mainly to install a filter screen with a much smaller aperture than the resin on the water system pipeline near the outlet of equipment equipped with a resin such as an ion exchanger and has the function of flushing.

When the resin passes through, it can be intercepted and captured by the filter screen. At the same time, it will be flushed automatically through the front and rear differential pressure to discharge the captured resin out of the system.

At present, the filter screen in the resin capture device mainly adopts a single-layer or multi-layer nylon net as the resin capture unit. It is easy to be blocked after use for a certain time. The filter screen often needs to be replaced and backwashed regularly to discharge the captured resin out of the system. Shutdown operation is required in the process of replacing the filter screen and backwashing, resulting in the reduction of water treatment efficiency.

The purpose of the BLU-SZB-05 series is to provide a resin trap filter for a cation resin exchange device. The effluent of the cation resin exchanger enters the resin trapper to form a cyclone, which can make the resin trapper not easy to be blocked without backwashing, and realize the continuous operation of the cation resin exchanger.

Installation of BLU-SZB-05 series Resin Trap Filter 

The utility model comprises a shell, a rotating shaft rotationally connected in the shell, and a motor driving the rotation of the rotating shaft. A filter cartridge is fixed on the rotating shaft, an impeller is connected at the bottom of the filter cartridge, a water inlet is arranged on the sidewall of the shell along the tangent direction, a water outlet connected with the filter cartridge is arranged at the top, and a resin return port is arranged at the bottom.

The motor outside the shell drives the rotating shaft to rotate, and the rotating shaft drives the filter cartridge and impeller to rotate. Under the action of the impeller, the water in the shell forms a swirl, and the water with resin in the cation resin exchanger enters the shell along the tangent direction.

Under the action of swirling flow, the resin is separated from the water, moves away from the center of the shell and falls along the inner wall of the shell. The separated resin flows back from the resin return port to the cation resin exchanger, and the water without resin is discharged from the water outlet through the filter cartridge located in the center of the shell.

The cyclone in the cylinder can quickly separate the resin and water, greatly reduce the contact between the resin and the filter cylinder and avoid the blockage of the filter cylinder.

The swirling flow continuously washes the outer wall of the filter cartridge, which can also clean the filter cartridge, further reduces the possibility of filter cartridge blockage, eliminates the need for backwashing, greatly reduces the frequency of filter cartridge replacement, and can realize the continuous operation of cation resin exchanger.

Advantage of BLU-SZB-05 series Resin Trap Filter

By adopting the above technical scheme, the resin contains complete resin and broken resin. Under the action of swirling flow, the fine broken resin will be concentrated in the center of the shell and fall quickly under the action of water flow. By adjusting the flow of the resin discharge port, this part of the broken resin can be discharged from the resin discharge port at the bottom of the collecting hopper.

The relatively complete resin is subject to large centrifugal force due to its large mass. Most of the complete resin is far away from the center of the cylinder. Finally, it flows back from the resin return port on the sidewall of the hopper to the cation resin exchanger to separate the broken resin from the complete resin.

The broken resin is prevented from circulating in the cation resin exchanger all the time, which can improve the water treatment efficiency of the cation resin exchanger, reduce the broken resin concentration in the resin capture device, and avoid small broken resin from blocking the filter cartridge.

  1. The cyclone in the cylinder can quickly separate the resin and water, greatly reduce the contact between the resin and the filter cylinder and avoid the blockage of the resin trap filter.
    The swirling flow continuously washes the outer wall of the filter cartridge, which can also clean the filter cartridge, further reduces the possibility of filter cartridge blockage, eliminates the need for backwashing, greatly reduces the frequency of filter cartridge replacement, and can realize the continuous operation of cation resin exchanger.
  2. The outer wall of the resin trap filter is provided with a spiral convex part, and the lower side of the convex part is provided with a filter hole. After some resin hits the outer wall of the filter cartridge, it can fall along the upper side of the spiral convex part, and the water flows out from the filter hole on the lower side of the spiral convex part. Under the blocking effect of the spiral convex part, the filter hole can be kept unblocked to ensure the normal operation of the equipment.
  3. Under the action of swirling flow, the fine broken resin is concentrated in the center of the shell and discharged from the resin discharge port at the bottom of the collecting hopper, and the more complete resin flows back to the resin trap filter from the resin return port on the sidewall of the hopper, which can separate the broken resin from the complete resin.
