Description

Technical Field

[0001] The utility model relates to the technical field of resin regeneration, in particular to a device for regenerating chelating resin by utilizing nitric acid. Background Art

[0002] In the field of water treatment, ion exchange resins are widely used to remove soluble ions in water, such as cations and anions. These resins will become saturated after a period of time, that is, the ions they adsorb reach their maximum capacity. At this time, they need to be regenerated to restore their exchange capacity. Under normal circumstances, hydrochloric acid (HCl) or sulfuric acid (H2SO4) is used to regenerate cation exchange resins instead of nitric acid (HNO3). This is because hydrochloric acid and sulfuric acid can effectively replace the cations adsorbed on the resin, and they are relatively economical and easily available in water treatment applications. However, in certain specific cases, nitric acid may be used to regenerate the resin, which is mainly based on the following considerations: Oxidizing property: Nitric acid has strong oxidizing properties, which is beneficial in some cases. For example, if the resin is contaminated with organic matter, nitric acid can oxidize and decompose these organics, thereby helping to clean the resin; Special applications: In some industrial processes that require particularly pure water quality, such as semiconductor manufacturing, nitric acid may be used to avoid the introduction of unwanted impurities (such as chloride ions or sulfate ions); Metal ion removal: Nitric acid has a strong complexing ability for certain metal ions, which makes it a better choice in specific metal ion removal processes; pH control: In some processes, using nitric acid regeneration can better control the pH value of the final product. In actual applications, the choice of which acid to use for resin regeneration depends on the specific process requirements, cost considerations, safety factors and requirements for final product quality.

[0003] An existing device for regenerating a chelate resin using nitric acid is not convenient for cleaning the resin plate, scraping off the suspended matter and impurities on the surface of the resin plate and collecting the suspended matter and impurities during use, and is also not convenient for allowing the nitric acid solution to quickly and evenly penetrate the resin plate. A device for regenerating a chelate resin using nitric acid is currently available to solve the above problems. Utility Model Content
