Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an ion exchange device that can monitor resin leakage. Background Technology

[0002] Ion exchange technology is an indispensable core separation technology in many industrial fields, including modern water treatment, hydrometallurgy, food and pharmaceutical manufacturing, and chemical synthesis. Its core equipment—the ion exchanger—selectively removes or converts ionic substances in a solution using special synthetic resin materials, thereby achieving solution purification, softening, refining, and resource recovery. Since the advent of synthetic ion exchange resins in the mid-20th century, this technology has become a pillar process for high-purity water preparation and the separation of specific substances due to its high efficiency, high selectivity, and relatively simple operation. Despite challenges from emerging technologies such as membrane technology, ion exchangers, with their unique advantages, remain irreplaceable in many applications and continue to demonstrate their vitality.

[0003] In industrial fields such as water treatment and chemical purification, resin exchangers, with their highly efficient ion-selective adsorption capabilities, have become key equipment for achieving water purification and substance separation. Among them, anion exchangers, cation exchangers, and chelate exchangers, due to differences in their mechanisms of action and applicable scenarios, together constitute the core system of ion exchange technology, providing customized solutions for the purification needs of different industries.

[0004] Cation exchanger: A "pioneer" in removing cations from water

[0005] Cation exchangers use cation exchange resins as the core adsorption medium, and their working principle is based on exchangeable cations (such as H+) on the resin framework. + Na + ) and cations to be removed from water (such as Ca) 2+ Mg 2+ Fe 3+ (etc.) undergo a displacement reaction.

[0006] Anion exchange resin exchangers: "precision filters" for retaining anions.

[0007] Complementing cation exchangers, anion exchangers, with anion exchange resins at their core, focus on removing anionic impurities from water (such as Cl-). - SO4 2- NO3 - SiO3 2- (etc.). Its working mechanism is based on exchangeable anions (such as OH-) on the resin backbone. - Cl -) It replaces anions in water; for example, when a strongly basic anion exchange resin is used, the OH- ions in the resin... - It can react with Cl in water - SO4 2- Exchange, while neutralizing H in the water + (From cation exchange), ultimately producing pure water with low ion content.

[0008] Chelating resin exchangers: "special effect devices" for targeted capture of heavy metals.

[0009] The core difference between chelating resin exchangers and the previous two types of equipment lies in the use of special resins with chelating functional groups (such as aminodiacetic acid groups and oxime groups). These resins' functional groups can react with heavy metal ions in water (such as Pb). 2+ Hg 2+ Cd 2+ Ni 2+ They form stable chelates, which can achieve high-efficiency adsorption even at low concentrations (ppm level), and have extremely low selectivity for common light metal ions such as calcium, magnesium, and sodium, thus avoiding interference from irrelevant ions.

[0010] In summary, cation and anion exchangers are the "basic partners" in industrial water treatment, achieving comprehensive ion removal through complementary effects; while chelate exchangers are a "specialized tool" for heavy metal pollution, providing efficient solutions for environmental protection and resource recycling. These three technologies can be flexibly combined according to different application scenarios to jointly promote the continuous development of ion exchange technology in water purification, resource recycling, and other fields.

[0011] Ion exchange resin is the core of an ion exchanger, but resin leakage has occurred in most fields. This not only results in economic losses, but also causes great trouble to the operation and maintenance of the equipment and the stability of the subsequent system operation.

[0012] Typical ion exchanger resin leakage problems generally involve at least one of the following issues:

[0013] (1) The water cap at the bottom of the ion exchanger was not properly selected, and the gap was too large, resulting in resin leakage;

[0014] (2) The bottom water cap of the ion exchanger is loose, and the precision wire-wound tubes of the middle drain and inlet are loose, resulting in resin leakage;

[0015] (3) Resin leaked from the exhaust pipe;

[0016] (4) Improper operation leads to resin leakage.

[0017] Therefore, there is an urgent need to provide an ion exchange device that prevents resin leakage and monitors the resin leakage situation so that it can be detected and dealt with in a timely manner to avoid losses. Utility Model Content

A vertically placed resin trap 17 has a resin trap outlet pipe at its upper end and a resin trap drainage pipe 16 at its lower end. Downstream of the equipment backwash inlet 8, there is also an equipment regeneration acid / alkali inlet 9, which is a T-shaped inlet. Opposite to the equipment regeneration acid / alkali inlet 9 is the equipment forward wash outlet 13, which is connected to a forward wash drainage pipe. The intermediate discharge pipe 4, forward wash drainage pipe, backwash drainage pipe, and resin trap drainage pipe 16 all end in a drainage ditch 14. Normally, wastewater enters the ion exchange equipment through the equipment inlet 7 and inlet pipe, undergoing ion exchange reaction in the resin layer. The low-hardness permeable water after the reaction is discharged through the outlet pipe and enters the subsequent treatment system after passing through the resin trap 17. After the resin becomes saturated, it is regenerated to restore its original treatment function.

[0039] This invention optimizes ion exchange equipment, such as...

Figure 1 As shown, there are multiple sight glass observation ports 10, which are located at different heights of the ion exchange equipment body 5, so that the internal medium can be observed on site.

[0041] In this invention, digital monitoring equipment is provided, such as... Figure 1As shown, all resin interception monitoring devices 3 are connected to a remote monitoring system. The remote monitoring system is located in the control room and can transmit the medium status in each drainage pipe to the control room for remote monitoring. Once a resin leak is detected, it can be dealt with in a timely manner to avoid losses.

[0042] In this invention, a precision basket resin trap 15 is provided in the drainage ditch 14 of the ion exchange equipment, such as... Figure 1 As shown, specifically, a precision basket resin trap 15 is installed downstream of the drainage ditch 14 to collect resin even if it leaks into the drainage ditch 14.
