Pellett resin is a commonly used variety in boiler equipment, and soft water resin is the core component of boiler soft water equipment.,Its quality is directly related to the boiler"UseEfficiency and service life: The raw water passes through the soft water resin, which can remove calcium and magnesium ions from the water, reduce water hardness and prevent the formation of scale.When the soft water resin has replaced a certain amount of hardness ions such as calcium and magnesium in the water, it can no longer soften the water. At this point, a water softener is needed to regenerate the resin, which is the reduction and regeneration method after the resin is contaminated by calcium.Now let's talk about how to regenerate the Perlite soft water resin used in boilers.

Step One

withNaWhen regenerating strong cation exchange resin with solution, it is advisable to adopt a stepwise regeneration method. Start at a low concentrationNaThe solution is regenerated because what is desorbed from the resin at this timeCa2+High concentration, butNaThe concentration is relatively low, even if a small amount is formedCa2+NaSediment can also be washed away by the solution. Then gradually improveNaThe concentration, which is desorbed from the resin at this timeCa2+Low concentration, no formationNaSedimentation.

Step Two

Since the weak cation exchange resin is regenerated with the regeneration waste liquid of the strong cation exchange resin. Therefore, while acid is being fed in, dilution water is also being fed into the weak cation exchanger(JF9201Filtered water)The inflow of water should be such that the liquid level does not exceed the acid inlet of the exchanger. In addition, pay attention to observing the color of the regeneration waste liquid discharged from the weak cation exchanger. If it appears as white turbid, adjust the concentration of the incoming acid immediately. Resin, etc.

Step Three

After the acid is fed in, the weak cation exchanger is immediately fed inJF9201The filtered water is replaced and cleaned, and the strong cation exchanger is immediately replaced and cleaned with refined water.

Precautions

　  Calcium contamination is more likely to occur in winter due to the low temperature of the regenerant. ThereforePerlite soft water resin for boilersBefore regeneration, the weak cation exchanger is scrubbed and backwashed, and the pipeline of the regeneration waste liquid between the weak cation exchanger and the strong cation exchanger is backflushed to prevent potential problems before they occur.
