Why use BLU-SZB-09 series Resin Trap Filter?
During the operation of cation bed, anion bed, and mixed bed of water treatment system in thermal power plant, if there are problems such as water cap damage, large water pressure disturbance (especially high-pressure disturbance), poor resin quality (insufficient strength, easy to break) and resin aging, the resin will enter the subsequent water treatment system and affect the normal operation of subsequent equipment of the system Resin traps are installed at the outlet of anion bed and mixed bed to recover the normal resin leaked by ion exchange equipment and prevent the broken resin from entering the subsequent system.
When the above abnormalities occur during the operation of the water treatment system, some resins entering the resin catcher sink at the bottom, some adhere to the outer wall of the filter element, and some are mixed in the gap of the filter element winding wire.
When there are too many attachments on the surface and gap of the filter element of the resin trapper, the pressure difference before and after the filter element increases, and the water passing capacity decreases. It is necessary to restore the water passing capacity by flushing the filter element. Otherwise, the operation quality of the ion exchanger will be affected and the production efficiency will be reduced. In serious cases, the filter element of the resin trapper will be damaged, the resin will enter the subsequent system, and the subsequent equipment cannot operate normally.
When the pressure difference between the front and back of the resin catcher is too large, the filter element of the resin catcher needs to be flushed. In the traditional process, firstly, the flow direction of the flushing water inlet is consistent with that of the water inlet medium during operation, and the broken resin mixed in the filter element gap on the upstream side of the filter element is difficult to remove; Secondly, in the whole flushing process, the direction of flushing force is single, the flushing water is lack of disturbance, the flushing effect is poor, the flushing time is long, and the flushing water is seriously wasted.
The distribution of flushing water power on the surface of the filter element is seriously uneven, and the flushing effect is poor in the area far from the flushing water inlet.
Installation of BLU-SZB-09 series Resin Trap Filter
The BLU-SZB-09 series resin trap filter provides a vertical resin trapper for water treatment in a thermal power plant, which overcomes the shortcomings of the prior art and can effectively solve the problems that it is difficult to remove the broken resin mixed in the filter element gap on the upstream side of the filter element, waste the flushing water and poor flushing effect when flushing the filter element of the resin trap.
The utility model relates to a vertical resin trap filter for water treatment in a thermal power plant, which comprises a cylinder, a water inlet is arranged at the lower part of the wedge wire screen cylinder, and a grease discharge port is arranged at the bottom of the cylinder.
A filter cartridge capable of intercepting resin and opening at the top is arranged in the barrel, the outer diameter of the filter cartridge is less than the inner diameter of the barrel, a water outlet pipe is fixed on the top of the barrel corresponding to the inner side of the filter cartridge, the top of the water outlet pipe is a water outlet, and a compressed air inlet is arranged on the water outlet pipe below the water outlet.
The cylinder includes a grease discharge section and a filter section corresponding to the inside and outside of the filter cylinder. The bottom end of the filter section is fixed with the top end of the grease discharge section. The water inlet is set on the filter section, the grease discharge port is set at the bottom of the grease discharge section, an upper connecting ring plate is set at the bottom of the water outlet pipe, a lower connecting ring plate corresponding to the upper and lower connecting ring plates is set at the top of the filter section, a convex edge is set at the top of the filter cylinder, and the upper connecting ring plate The convex edge and the lower connecting ring plate are fixedly installed together from top to bottom.
Advantage of BLU-SZB-09 series Resin Trap Filter
- The utility model has the advantages of a reasonable and compact structure and convenient use.
- Compressed air enters the filter cartridge from the compressed air inlet, and the air pressure on the inner wall of the filter cartridge is evenly distributed.
- The airflow is blown in the opposite direction to effectively remove the broken resin in the filter cartridge.
- After air scrubbing, scrub with air and water.
- In this process, the air and water phases disturb each other and act fully with the filter cartridge, so that the resin attached to the gap and surface of the filter cartridge is stripped.
- The resin trap filter is flushed to clear water in the bubble-free environment so that the duration of the flushing process is short, the flushing water is saved and the flushing effect is good.
