Storage of anion and cation exchange resin:

The fat of ion exchange trees contains a certain amount of water, which should be kept as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (-10%) first, and then gradually diluted. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. In long-term storage, strong type resins should be transformed into salt type, while weak type resins can be transformed into corresponding hydrogen type or free base type or salt type, and then soaked in clean water. During storage or transportation, the resin should be kept at 5-40In the temperature environment of C, avoid overcooling or overheating, which may affect the quality. If there is no insulation equipment in winter, the resin can be stored in saline solution, and the temperature of the saline solution can be determined according to the temperature.
Pre treatment of new resin:

New resins often contain solvents, substances that have not participated in polymerization reactions, and small amounts of low polymers, and may also adsorb heavy metal ions such as iron, aluminum, and copper. When the resin comes into contact with water, acid, alkali, or other solutions, the soluble impurities mentioned above will be transferred into the solution, contaminating the effluent quality in the early stages of use. So, the new resin needs to be pre treated before being put into operation.

Pre treatment of Yang resin

The pretreatment steps for cation resin are as follows:

Firstly, use saturated saline solution, which is approximately twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to ensure that the discharged water does not turn yellow; Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or perform a low flow cleaning), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral. Afterwards, use a 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and use a clear solution

Drift the water to neutral for later use.

Pre treatment of Yin Resin

The steps in its pretreatment method are the same as those in the cation resin pretreatment method; Then use

Soak in 5% HCl for 4-8 hours, then drain the acid solution and rinse with water until neutral; Then dissolve it in 2% -4% NaOH

After soaking in liquid for 4-8 hours, drain the alkaline solution and wash with clean water until neutral for later use.

Transportation and storage of cation exchange resin:
Ion exchange resin contains a certain amount of moisture, which should be maintained as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (8-10%) for 1-2 hours before gradually diluting. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. During storage or transportation, the resin should be kept in a temperature environment of 5-40 ℃ to avoid overcooling or overheating, which may affect its quality. If there is no insulation equipment in winter, the resin can be stored in saline solution, and the temperature of the saline solution can be determined according to the temperature.

The utility model discloses a boiler water deionization treatment system, comprising a mixed bed water supply pump, an ion exchange mixed bed, and a resin trap arranged in sequence along the water flow direction. The ion exchange mixed bed is equipped with uniformly mixed anion exchange resin and cation exchange resin; It also includes acid addition system and alkali addition system. This utility model adopts an ion exchange mixed bed to exchange ionic substances in water, and the anion exchange resin and cation exchange resin in the ion exchange mixed bed are uniformly mixed, so that the exchange of anions and cations is almost simultaneous, eliminating the influence of reverse reactions. Therefore, using this treatment system to deionized boiler water can obtain high-purity deionized water quality; And after using the ion exchange mixed bed for a period of time, adding hydrochloric acid and * solution to the ion exchange mixed bed through the acid and alkali addition system can regenerate the ion exchange mixed bed and enable the long-term stable operation of this treatment system.
