To replace the boiler softening water resin, first introduce the composition, principle and replacement cycle of the boiler softening water resin. Overview of the resin This model is a strong sodium type with golden yellow spherical particles. It is mainly used for hard water softening, pure water preparation, and malic acid. And the removal of citric acid has a good effect. Resin description This product is an ion exchange resin with a sulfonic acid group (-SO3H) on the polymer matrix of styrene-=vinylbenzene copolymerization and crosslinking structure. Its acidity is equivalent to inorganic acid. It is alkaline, neutral, and even All acid media show ion exchange function. This product has the characteristics of high exchange capacity, fast exchange speed, and good mechanical strength. Description of softening resin: This product is mainly used for hard water softening, pure water preparation, hydrometallurgy, separation of rare elements, extraction of antibiotics, etc. Executive standard: GB13659-92 Specifications: 1. Appearance: golden yellow to brown spherical particles. 2. Sodium Star Water softening resin.
Please pay attention to the following points when replacing resin:
1: First check whether the equipment can work normally and whether the controller is damaged, so that it can work normally after replacing the new resin and use it normally.
Two: Turn off the power if everything is normal. Before replacing the resin, first turn on the backwashing position of the softening water equipment, and fully backwash to loosen the compacted resin in the resin barrel.
3: Open the inlet and outlet pipes of the control valve, remove the sewage pipe and salt suction pipe, and unscrew the water softener control valve. Resin barrels with a diameter of less than 400 can be poured directly into the resin barrels, and the resin can be poured out. If the diameter is above 400, use a vacuum siphon method to suck out the resin.
4: Fix the center tube and seal the center tube with tape (to prevent quartz sand and resin from entering the lifting tube) and slowly put the processed resin into the resin tank around the center tube.
Put the control valve back into the resin bucket, and connect the inlet and outlet pipes, sewage pipes, and salt suction pipes.
5: Open the outlet valve, and slowly open the outlet valve.
Six: Take the softened water from the sampling port for testing, and it is qualified.
