Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, specifically, relate to a kind of ion exchanger. BACKGROUND

[0002] Ion exchanger plays a vital role in water treatment, pharmaceutical, food processing and chemical industry. It effectively removes precipitates and ions in water by adsorption and release of ions, thereby purifying water quality or realizing separation of specific substances. The core component of ion exchanger is ion exchange resin, which is composed of polymer with charged sites. Ion exchange process occurs at charged sites. Currently, most of the synthesized ion exchange resins are prepared from porous microspheres. The surface properties and pore size of these porous microspheres provide suitable conditions for ion attachment. As the ion exchange process proceeds, the exchangeable ions on the resin are gradually replaced by ions in water. When the exchange capacity of the resin approaches saturation, the resin will be ineffective and cannot continue to effectively exchange ions. At this time, the resin needs to be regenerated to restore its exchange capacity. Alkaline solutions such as sodium hydroxide are commonly used as regenerants. OH- in the alkaline solution will exchange with the adsorbed anions on the anion exchange resin, washing the anions off, and the resin will regain exchangeable OH-, achieving regeneration. The flow direction of the regenerated solution and the original water is opposite, i.e. from the lower part of the ion exchanger to the upper part. Countercurrent regeneration can improve the utilization rate of regenerant, reduce regenerant consumption, improve water quality, reduce cleaning water consumption and regeneration waste liquid discharge. However, in actual use, resin will deposit in large quantities at the bottom of the exchanger during long-term exchange, blocking part of the regeneration pipeline and reducing the regeneration treatment effect.

[0028] Referring to Figs. 1 to 3The utility model discloses an ion exchanger, including jar body 100 and filter plate 200, wherein, the upper portion of jar body 100 is provided with water inlet pipeline 110, the lower portion of jar body 100 is provided with backwashing pipeline 120, and the bottom of jar body 100 is provided with drain pipeline 130, be provided with reaction cavity 140 in jar body 100, filter plate 200 is set up in jar body 100, reaction cavity 140 is divided into reaction chamber 141 and clarification chamber 142 with filter plate 200, water inlet pipeline 110 is set up in reaction chamber 141, and backwashing pipeline 120 and drain pipeline 130 are set up in clarification chamber 142, be provided with a plurality of first recess 210 on filter plate 200, and the both sides of first recess 210 are provided with first filter hole 211 respectively. Specifically, in the conventional treatment stage, the raw water containing precipitate and ion flows into reaction chamber 141 through the water inlet pipeline 110 on the upper portion of jar body 100. In reaction chamber 141, raw water is in full contact with the corresponding ion exchange medium, such as ion exchange resin, ion exchange reaction occurs, target precipitate ions in water are removed, and preliminary purification of water quality is realized. After ion exchange reaction, water flows to filter plate 200, filtered water enters clarification chamber 142, and finally is discharged from the drain pipeline 130 at the bottom of jar body 100, completing the entire conventional treatment process. Filter plate 200 divides reaction cavity 140 into reaction chamber 141 and clarification chamber 142, so that ion exchange reaction and clarification filtration process are relatively independent and orderly connected. This partition design helps to improve the treatment efficiency of each stage and ensure the water treatment effect. In the backwashing stage, when backwashing is needed, water flows from the backwashing pipeline 120 at the lower portion of jar body 100 into clarification chamber 142. Backwashing pipeline 120 is arranged in clarification chamber 142 to ensure that backwashing water can flow reversely through the entire treatment area. Backwashing water flows reversely through filter plate 200 and enters reaction chamber 141. In this process, the water flow impacts first recess 210 and first filter hole 211 on filter plate 200. Because the water flow direction is opposite to that in the conventional working stage, and the first filter hole 211 on the both sides of first recess 210 forms a special flow path for the water flow, vortex and turbulence are generated. Vortex and turbulence help to loosen the precipitate and precipitate attached around first filter hole 211 and in first recess 210. With the flow of water in first recess 210, these loosened precipitate are entrained by the water flow and follow the direction of backwashing water flow, realizing self-cleaning of first filter hole 211 and restoring its smoothness. The reverse water flow and special structure of filter plate 200 in the backwashing stage can effectively prevent the accumulation and blockage of precipitate in the filter hole and reaction chamber 141. The special water flow pattern formed by first recess 210 and first filter hole 211 enhances the scouring ability of precipitate, making it difficult for precipitate to adhere to the key parts and prolonging the service life of the equipment.

[0029] In some embodiments of the utility model, the second groove 220 is formed by concave in the central position of filter plate 200, and the second filter hole 221 is arranged on the second groove 220, and the first groove 210 is radially arranged on the side of second groove 220. Specifically, in this embodiment, raw water flows into the reaction chamber 141 through the water inlet pipe 110 on the upper part of the tank 100. In the reaction chamber 141, raw water and ion exchange medium carry out ion exchange reaction, and remove part of impurity ions in water. In the backwashing stage, water flows into the clarification chamber 142 through the backwashing pipe 120 on the lower part of the tank 100, and then enters the reaction chamber 141 through the filter plate 200 in reverse. In the first groove 210, the design of the first filter hole 211 on both sides of the first groove 210 can form impact on both sides of the first groove 210, so as to form vortex and turbulence, and the scouring force on the precipitate is enhanced, and at the same time, the position of the first groove 210 can form tangential impact on the surface of the second groove 220, so as to loosen the stubbornly adhered precipitate. Thus, the backwashing effect is provided.

[0030] In some embodiments of the utility model, the cross section of the first groove 210 is semicircular, and one end of the first groove 210 is communicated with the second groove 220. Specifically, in this embodiment, the semicircular first groove 210 is matched with the first filter hole 211, which greatly enhances the water flow disturbance effect during backwashing. The formation of vortex and turbulence can more effectively flush away the precipitate accumulated on the first groove 210 and the first filter hole 211 for a long time, and the tangential impact on the second groove 220 also helps to clean the stubborn precipitate in the second groove 220, which improves the cleaning ability of backwashing. Through the structure design, the ion exchanger can realize more efficient self-cleaning in the backwashing stage. The frequency and difficulty of manual cleaning are reduced, the maintenance cost is reduced, the performance of the equipment can be better maintained, the service life of the equipment is prolonged, and the long-term stable operation of the ion exchanger is ensured.

[0031] In some embodiments of the utility model, the second filter hole 221 is arranged in a honeycomb shape on the filter plate 200. Specifically, in this embodiment, the regular arrangement of the honeycomb shape makes the filtration of the second filter hole 221 more uniform, avoids the situation that the local filtration pressure is too large or too small, ensures that the filtration effect of each area is consistent, improves the stability of the water quality, and can improve the structural strength of the filter plate 200.

[0032] In some embodiments of the utility model, inlet pipeline 110 includes main pipeline 111 and branch pipeline 112, branch pipeline 112 is provided with multiple, multiple branch pipeline 112 is along the axis of main pipeline 111 is arranged and is communicated main pipeline 111 respectively. Specifically, in this embodiment, raw water with sediment and ion first enters inlet pipeline 110. Inlet pipeline 110 is composed of main pipeline 111 and multiple branch pipeline 112, and multiple branch pipeline 112 is arranged along the axis of main pipeline 111 and is communicated with main pipeline 111 respectively. This structure design makes raw water flow in main pipeline 111 can be evenly distributed into each branch pipeline 112. Each branch pipeline 112 transports raw water to different positions on the upper portion of the tank 100, so that raw water flows into the reaction chamber 141 more evenly.

[0033] In some embodiments of the utility model, one end of main pipeline 111 is provided with water inlet 113, and the other end of main pipeline 111 is provided with water outlet 114 penetrating through tank 100, specifically, in this embodiment, during backwashing, water flows from the lower portion of tank 100 backwashing pipeline 120 into clarification chamber 142, and passes through filter plate 200 into reaction chamber 141 in reverse. With the backwashing, the water flow carrying sediment increases, and the water outlet 114 penetrating through the tank 100 at the other end of the main pipeline 111 serves as the overflow port of backwashing water at this time, and the excess backwashing water carrying loosened sediment overflows from the water outlet 114 and is discharged out of the body.

[0034] In some embodiments of the utility model, a first non-return valve 115 is arranged at the inlet pipeline, and a second non-return valve 116 is arranged at the water outlet 114. Specifically, in this embodiment, raw water enters from the water inlet 113 at one end of the pipeline, and flows through the first non-return valve 115 arranged at the inlet pipeline. In the normal working state, the first non-return valve 115 is in the open state, allowing raw water to pass smoothly into the main pipeline 111. The main pipeline 111 transports raw water to the vicinity of the tank 100, and the multiple branch pipelines 112 arranged along the axis of the main pipeline 111 evenly distribute the raw water in the main pipeline 111, and then introduce the raw water into the upper portion of the tank 100, so that the raw water flows into the reaction chamber 141 more evenly. When backwashing is needed, first close the first non-return valve 115 to cut off the inflow of raw water. Then open the second non-return valve 116 to provide an overflow channel for backwashing water.

[0035] In some embodiments of the present application, a pressure relief valve 150 is provided on the upper end of the tank 100. Specifically, in this embodiment, during backwashing, gas can be introduced in a certain proportion. The introduction of gas will form a gas-liquid mixed flow state in the tank 100. The bubbles of the gas will produce additional stirring effect on the filter plate 200 and the internal structure of the tank 100 during the rising process, further enhancing the stripping and loosening effect on the precipitate. For example, when the bubbles break around the second groove 220 and the first groove 210, local impact force will be generated, helping to remove stubborn precipitates attached to these parts. When the pressure in the tank 100 reaches a threshold value, the pressure relief valve 150 ensures that the pressure in the tank 100 remains constant.

[0036] In some embodiments of the present application, a plurality of guide plates 300 are arranged on the inner circumferential wall of the tank 100, and the plurality of guide plates 300 are arranged in a spiral shape. Specifically, in this embodiment, a plurality of guide plates 300 arranged in a spiral shape are arranged on the inner circumferential wall of the tank 100. When the water flow enters the reaction chamber 141, the guide plates 300 begin to play a role. The spiral guide plates 300 guide the water flow to move downward along the inner circumferential wall of the tank 100 in a spiral shape. This spiral flow mode makes the water flow form a relatively stable and orderly rotating flow field in the tank 100. On the one hand, the contact time of the water flow with the ion exchange medium is prolonged during the spiral downward movement. Because the water flow does not flow directly and quickly to the filter plate 200, but slowly descends along the spiral path, the ions in the raw water have more opportunities to react with the ion exchange medium, thereby improving the efficiency of ion exchange and more effectively removing ion impurities in the water. On the other hand, the spiral water flow movement helps to make the water flow more evenly distributed in the tank 100. It avoids the situation that the water flow is concentrated in a certain area of the tank 100, so that the ion exchange reaction in the entire reaction chamber 141 can be carried out more evenly, improving the consistency of the treatment effect.

[0037] In some embodiments of the present application, at least one observation window 170 is provided on the outer circumferential wall of the tank 100. Specifically, in this embodiment, the observation window 170 provided on the outer circumferential wall of the tank 100 provides a way for the operator to directly observe the internal condition of the tank 100.

[0038] The embodiments of the present application are described in detail above in combination with the drawings, but the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present application.
