Description

Technical Field

[0001] This utility model relates to the field of purification, and in particular to a neutralization system and a waste liquid purification system. Background Technology

[0002] In existing technologies, neutralization systems do not separately treat the precipitate and clear liquid produced by the chemical reaction, resulting in low processing efficiency and precision. The precipitate contains unreacted reagents, various impurities, and part of the clear liquid, while the clear liquid also contains fine precipitate particles. This mixed state greatly interferes with subsequent processing, prolongs purification time, and increases costs. Utility Model Content

[0003] Therefore, it is necessary to provide a neutralization system and a waste liquid purification system to address the problem that the sediment and clear liquid in the neutralization system are not treated separately.

[0004] A neutralization system comprising: a waste liquid assembly for storing and conveying waste liquid; a dosing assembly for conveying a drug and adjusting the pH of the solution; and a neutralization device connected to the waste liquid assembly and receiving the waste liquid conveyed by the waste liquid assembly, and connected to the dosing assembly and receiving the drug conveyed by the dosing assembly.

[0005] The above discloses a neutralization system for wastewater purification. First, the wastewater component efficiently stores and stably delivers wastewater, providing a continuous source of wastewater for the entire treatment process and ensuring uninterrupted treatment. The dosing component precisely delivers chemicals based on the real-time composition and pH of the wastewater, flexibly adjusting the solution's pH value. This allows the neutralization reaction within the neutralization unit to occur under optimal conditions, greatly improving reaction efficiency and ensuring reaction integrity. The chemical reaction in the neutralization unit generates a clear liquid and precipitate, effectively separating metal ions from the wastewater and laying a solid foundation for subsequent advanced treatment. The clear liquid can directly enter subsequent purification stages, reducing treatment steps and time costs; the precipitate can be further recycled, achieving efficient resource utilization. This neutralization system, through the coordinated operation of its components, optimizes the wastewater treatment process, improves treatment efficiency and quality, and achieves the goals of efficient resource utilization and environmental friendliness. This not only helps PCB printed circuit board manufacturers reduce production costs but also enhances their social image and sustainable development capabilities, providing strong support for the industry's green development.

[0006] In one embodiment, the neutralization device includes at least two neutralization components, each connected to both the waste liquid component and the dosing component. These two components alternately receive waste liquid and chemicals and alternately output clear liquid and precipitate. By using at least two neutralization components, the wastewater treatment process is significantly optimized. Since both components are connected to the waste liquid component and the dosing component and can alternately receive waste liquid and chemicals and output clear liquid and precipitate, treatment efficiency is significantly improved. While the first neutralization component is discharging clear liquid and precipitate, the second neutralization component can receive waste liquid and chemicals for neutralization. Once the reaction is complete, the resulting precipitate settles completely to the bottom of the neutralization component. When the first neutralization component has completely discharged, the second component can then discharge clear liquid and precipitate, achieving seamless operation and avoiding interruptions to the treatment process. This alternating operating mode also ensures stable system operation. If a single component operates continuously for a long time, wear and tear or malfunctions are likely to occur. Alternating operation of the two components effectively distributes workload and reduces equipment wear. Even if one component suddenly fails, the other component can be immediately put into use, ensuring that wastewater treatment is not affected. Furthermore, it can further improve the effect and efficiency of the neutralization reaction, helping the entire waste liquid purification system to operate more efficiently and stably, and providing strong support for PCB printed circuit board factories to achieve green production goals.

[0007] In one embodiment, the neutralization device includes a first neutralization component and a second neutralization component. Both the first and second neutralization components are connected to the waste liquid component and the dosing component. The first and second neutralization components alternately receive waste liquid and chemicals and alternately output clear liquid and precipitate. By connecting both the first and second neutralization components to the waste liquid component and the dosing component, when the first neutralization component is discharging clear liquid and precipitate, the second neutralization component can input waste liquid and chemicals for neutralization. Once the reaction is complete, the resulting precipitate completely settles to the bottom of the second neutralization component. When the first neutralization component has completely discharged, the second neutralization component can then discharge clear liquid and precipitate, achieving seamless operation, significantly improving treatment efficiency, and reducing overall treatment time. Simultaneously, this alternating working mechanism effectively ensures the stable operation of the system. Long-term continuous operation of a single neutralization component is prone to wear and tear and malfunction, while the alternating operation of two components can distribute the workload, reduce equipment wear, and extend equipment lifespan. Moreover, if one component suddenly fails, the other component can immediately take over, ensuring that wastewater treatment is not affected and maintaining the continuous operation of the system. Furthermore, the alternating operation of the two components allows the dosing unit to more precisely adjust the dosage of the reagents according to the reaction requirements of different amounts of wastewater, further improving the effect and efficiency of the neutralization reaction. This helps the entire wastewater purification system operate efficiently and stably, providing a solid guarantee for the green production of PCB printed circuit board factories.

One end of the second inlet is disposed in the second water tank assembly, and the other end of the second inlet is connected to the waste liquid assembly. One end of the second discharge assembly is disposed in the second water tank assembly, and the other end of the second discharge assembly is connected to an external system. The dosing assembly is disposed on the second water tank assembly. By connecting one end of the first inlet of the first neutralization component to the first water tank assembly and the other end to the waste liquid assembly, the wastewater to be treated can be quickly introduced into the first water tank assembly. The dosing assembly is disposed on the first water tank assembly, allowing for precise addition of chemicals according to the actual condition of the wastewater, enabling the wastewater to undergo a complete neutralization reaction within the first water tank assembly, promoting the precipitation of pollutants such as metal ions. The first discharge component transports the reacted clarified liquid and precipitate to an external system, preparing for subsequent treatment. Similarly, the second inlet component, the second water tank component, and the second discharge component of the second neutralization component work together to ensure the continuity of wastewater treatment. While the first neutralization component is discharging clarified liquid and precipitate, the second neutralization component can initiate the neutralization reaction in advance and wait for the precipitate to completely settle to the bottom of the second water tank component. Once switched, it can quickly begin operation, using the second discharge component to discharge clarified liquid and precipitate, achieving seamless connection of the wastewater treatment process and greatly improving treatment efficiency. The first and second neutralization components, with their rational structural design, work in conjunction with the entire wastewater purification system to effectively improve wastewater treatment efficiency and quality, reduce treatment costs, and minimize environmental pollution, providing strong support for PCB printed circuit board factories to achieve green and efficient production.

[0009] In one embodiment, the first water tank assembly includes a first water tank body, a first sedimentation baffle, a first stirrer, and a first acid-base detector. The first inlet, the first outlet, and the dosing assembly are disposed on the first water tank body. The first sedimentation baffle and the first stirrer are disposed on two opposing inner sidewalls of the first water tank body. The first acid-base detector is disposed on the first water tank body. By disposing the first inlet, the first outlet, and the dosing assembly on the first water tank body, the functions of introducing wastewater and chemicals and discharging treated liquid are respectively realized, ensuring the continuity of the neutralization process. The first sedimentation baffle, disposed on the inner sidewall of the first water tank body, can effectively promote the separation of sediment. During the neutralization reaction, it can guide the sediment to settle rapidly, preventing sediment from flowing out with the clear liquid, improving the purity of the clear liquid, and providing high-quality influent for the subsequent purification system. The first stirrer can quickly stir the wastewater and chemicals during the neutralization reaction, ensuring thorough mixing, accelerating the chemical reaction, and improving the neutralization efficiency. The first acid-base detector monitors the acidity and alkalinity of the liquid in the water tank in real time, providing accurate data support for the dosing assembly. Based on this data, the dosing unit adjusts the dosage of the reagent in a timely manner to ensure that the neutralization reaction is always in the optimal acid-base environment, thereby further improving the effectiveness and stability of the neutralization reaction.

One end of each device is mounted on the first water tank assembly, and the other end is connected to the external system. The first clear liquid discharge device discharges the clear liquid, and the first sediment discharge device discharges the sediment. By separately mounting the first clear liquid discharge device and the first sediment discharge device on the first water tank assembly, with one end discharging the clear liquid and the other discharging the sediment, precise separation and discharge of the clear liquid and sediment are achieved. After the neutralization reaction is complete, the first clear liquid discharge device can quickly transport the pure clear liquid to the external system, providing high-quality feed water for subsequent deep purification, reducing the burden of impurities in the clear liquid on the purification system, and improving the efficiency of the purification system and the quality of the produced pure water. The first sediment discharge device can orderly discharge the sediment to the corresponding treatment stage, facilitating further treatment and recovery of impurities such as metals in the sediment. This precise discharge design avoids the mixing of clear liquid and sediment, optimizes the subsequent treatment process, and improves the overall treatment effect of the waste liquid purification system. The components of the first emission assembly work together in close coordination with the other parts of the first neutralization assembly and the entire wastewater purification system to ensure the efficient and orderly operation of the wastewater treatment process.

[0011] In one embodiment, the second water tank assembly includes a second water tank body, a second sedimentation baffle, a second stirrer, and a second acid-base detector. The second inlet, the second outlet, and the dosing assembly are disposed on the second water tank body. The second sedimentation baffle and the second stirrer are disposed on two opposing inner sidewalls of the second water tank body. The second acid-base detector is disposed on the second water tank body. By placing the second inlet, the second outlet, and the dosing assembly on the second water tank body, the flow of wastewater input, treated liquid discharge, and reagent addition is ensured to be smooth. The second sedimentation baffle accelerates sedimentation, allowing the clear liquid to separate quickly from the sediment, preventing sediment from mixing with the clear liquid, and providing high-quality influent for subsequent purification. The second stirrer can fully stir the wastewater and reagents, promoting rapid neutralization reaction and improving treatment efficiency. The second acid-base detector monitors the pH in real time, providing data support for the dosing assembly to achieve precise dosing and ensure that the neutralization reaction takes place under optimal conditions. The second water tank assembly works in conjunction with other components of the system, improving the treatment capacity and stability of the entire wastewater purification system and helping printed circuit board plants to efficiently treat wastewater.

[0012] In one embodiment, the second discharge assembly includes a second clear liquid discharge component and a second sediment discharge component. One end of each component is mounted on the second water tank assembly, and the other ends are connected to the external system. The second clear liquid discharge component discharges the clear liquid, and the second sediment discharge component discharges the sediment. By connecting the second clear liquid discharge component and the second sediment discharge component to the second water tank assembly and the external system respectively, precise separation and discharge of the clear liquid and sediment are achieved. After the reaction is complete, the second clear liquid discharge component can quickly transport the pure clear liquid to the subsequent purification system, reducing the processing burden on the purification system and improving purification efficiency and the quality of pure water output. The second sediment discharge component orderly discharges the sediment to corresponding stages such as the reflux acid washing system, facilitating further treatment and recovery of metal impurities in the sediment and preventing the mixing of clear liquid and sediment from interfering with subsequent processes. This precise discharge design optimizes the connection between various stages of the wastewater purification system, improves the overall treatment effect, and works collaboratively with other components of the system to ensure the efficient and orderly operation of the wastewater treatment process.

[0013] In one embodiment, the waste liquid assembly includes a waste liquid tank, a waste liquid output pipe, and a waste liquid control component. One end of the waste liquid output pipe is disposed on the waste liquid tank, and the other end of the waste liquid output pipe is connected to the neutralization device. The waste liquid control component is disposed on the waste liquid output pipe. By connecting one end of the waste liquid output pipe to the waste liquid tank and the other end to the neutralization device, the wastewater stored in the waste liquid tank is efficiently transported to the neutralization stage, initiating the subsequent treatment process. The waste liquid control component disposed on the waste liquid output pipe plays a crucial regulatory role. It can precisely control the output flow rate and velocity of the waste liquid based on the real-time processing capacity and demand of the neutralization device. When the system processing load is large, the waste liquid output velocity is appropriately reduced to prevent the neutralization device from being affected by excessive processing volume; when the processing load is small, the waste liquid output volume is increased in a timely manner to fully utilize the equipment capacity and improve the overall processing efficiency. Through the effective regulation of the waste liquid control component, the wastewater is ensured to enter the neutralization device stably and orderly, closely cooperating with the entire waste liquid purification system, improving the stability and processing efficiency of the system operation.

[0014] In one embodiment, the waste liquid control component includes a buffer, an overflow pipe, a waste liquid flow meter, and a waste liquid pump. The buffer, the waste liquid flow meter, and the waste liquid pump are installed on the waste liquid output pipe, and the overflow pipe is installed on the buffer. By installing the waste liquid pump on the waste liquid output pipe, power can be provided to ensure a stable and continuous delivery of waste liquid from the waste liquid tank to the neutralization device, avoiding interruptions in delivery due to insufficient power and ensuring the continuity of the wastewater treatment process. The waste liquid flow meter monitors the waste liquid flow in real time, providing accurate data for system regulation. Based on the flow data, operators can flexibly adjust the operating parameters of the waste liquid pump to match the waste liquid output with the processing capacity of the neutralization device, improving overall processing efficiency. The buffer plays a buffering and regulating role; when the waste liquid flow fluctuates, it can temporarily store excess waste liquid, preventing sudden flow changes from impacting the neutralization device. The overflow pipe connected to the buffer provides protection for the waste liquid assembly. When the waste liquid in the buffer reaches a certain level, the overflow pipe automatically opens to discharge excess waste liquid, preventing damage to the buffer due to excessive liquid level and ensuring safe system operation. The various components of the waste liquid control assembly work collaboratively and closely cooperate with other components of the waste liquid assembly to ensure stable and accurate waste liquid delivery, laying a solid foundation for the efficient and stable operation of the entire system.

[0015] In one embodiment, the dosing assembly includes a dosing tank, a dosing pipeline, a dosing control component, and a dosing output component. The dosing pipeline is mounted on the dosing tank, the dosing control component and the dosing output component are mounted on the dosing pipeline, and the dosing output component is mounted on the neutralization device and / or an external system. By connecting the dosing pipeline to the dosing tank, the chemicals can be delivered to subsequent stages. The dosing control component, installed on the dosing pipeline, can precisely control the flow rate and velocity of the chemicals based on real-time data such as waste liquid composition, pH, and neutralization reaction progress. This ensures that the added chemicals meet the reaction requirements while avoiding excessive waste and reducing treatment costs. The dosing output component, located on the dosing pipeline and connected to the neutralization device and / or an external system, can accurately deliver the precisely controlled chemicals to the neutralization device, promoting a complete neutralization reaction, effectively precipitating contaminants such as metal ions, and improving the neutralization effect. Connecting to an external system also allows for flexible handling of special dosing requirements in different scenarios. The components of the dosing unit work together in close coordination with other components of the waste liquid purification system, providing strong support for the efficient and stable operation of the entire system and helping PCB printed circuit board factories achieve high-quality wastewater treatment.

[0016] In one embodiment, the dosing control component includes a dosing flow pump and a dosing flow control valve, both mounted on the dosing pipeline. By mounting the dosing flow pump and the dosing flow control valve on the dosing pipeline, stable and precise power can be provided, accurately controlling the dosage of the reagent based on system feedback data. Whether the neutralization system requires a large amount of reagent for rapid pH adjustment or a small amount of reagent is needed for fine-tuning in the later stages of the reaction, the dosing flow pump can flexibly respond, ensuring a stable supply of reagents. The two components work together to enable the dosing system to precisely adapt to the needs of each treatment stage, maintaining the optimal pH environment within the system, greatly improving reaction efficiency and effectiveness, and working closely with the entire wastewater purification system.

[0017] In one embodiment, the dosing output component includes a first output, a second output, and a third output. One end of each of the first, second, and third outputs is disposed on the dosing pipeline, the other end of the first and second outputs is disposed on the neutralization device, and the other end of the third output is disposed on the external system. By connecting one end of the first and second outputs to the dosing pipeline and the other end to the neutralization device, the reagents can be precisely delivered to meet the needs of different reaction zones within the neutralization device. While one neutralization component is outputting the precipitate and clear liquid after the neutralization reaction, the reagent can be added to another neutralization component to carry out the neutralization reaction, ensuring that the neutralization system can operate uninterruptedly and improving work efficiency. The third output is connected to the dosing pipeline at one end and to the external system at the other end, providing the desired acid-base environment to the external system and ensuring that the external system can operate stably and normally.

[0018] The second aspect of this application discloses a waste liquid purification system, which includes the above-mentioned neutralization system.

[0019] The second aspect disclosed above discloses a wastewater purification system. A neutralization system serves as a pre-treatment step for the wastewater purification system. Through precise addition of chemicals via a dosing system, the neutralization system effectively adjusts the pH of the wastewater. During this process, metal ions in the wastewater react chemically with the chemicals, separating from the wastewater and forming precipitates. On one hand, it removes the main pollutants from the wastewater, significantly reducing the burden on subsequent treatment processes and creating favorable conditions for the efficient operation of subsequent purification processes. On the other hand, the effective separation of metal ions makes wastewater treatment more thorough, greatly reducing wastewater pollution to the environment, lowering heavy metal emissions, and meeting environmental protection requirements.

Detailed Implementation

[0034] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0036] The neutralization system and waste liquid purification system of this utility model are described below with reference to the accompanying drawings.

[0037] Example 1

[0038] like Figures 1 to 10 As shown, this embodiment discloses a neutralization system, including: a waste liquid component 1, which is used to store and transport waste liquid; a dosing component 2, which is used to transport drugs and adjust the pH of the solution; and a neutralization device 3, which is connected to the waste liquid component 1 and receives the waste liquid transported by the waste liquid component 1, and is connected to the dosing component 2 and receives the drugs transported by the dosing component 2.

[0039] This application discloses a neutralization system for wastewater purification. First, wastewater component 1 efficiently stores and stably delivers wastewater, providing a continuous source of wastewater for the entire treatment process and ensuring uninterrupted treatment. Dosing component 2 precisely delivers chemicals based on the real-time composition and pH of the wastewater, flexibly adjusting the solution's pH. This allows the neutralization reaction within neutralization device 3 to occur under optimal conditions, significantly improving reaction efficiency and ensuring reaction integrity. The chemical reaction in neutralization device 3 generates a clear liquid and precipitate, effectively separating metal ions from the wastewater and laying a solid foundation for subsequent advanced treatment. The clear liquid can directly enter subsequent purification stages, reducing treatment steps and time costs; the precipitate can be further recycled, achieving efficient resource utilization. This neutralization system, through the coordinated operation of its components, optimizes the wastewater treatment process, improves treatment efficiency and quality, and achieves the goals of efficient resource utilization and environmental friendliness. This not only helps PCB (Printed Circuit Board) manufacturers reduce production costs but also enhances their social image and sustainable development capabilities, providing strong support for the industry's green development.

[0040] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the neutralization device 3 includes at least two neutralization components, both of which are connected to the waste liquid component 1 and the dosing component 2. The two neutralization components are used to alternately receive waste liquid and drugs and alternately output clear liquid and precipitate. By setting at least two neutralization components, the wastewater treatment process is greatly optimized. Both neutralization components are connected to the waste liquid component 1 and the dosing component 2, and can alternately receive waste liquid and drugs and output clear liquid and precipitate, significantly improving treatment efficiency. When the first neutralization component is discharging clear liquid and precipitate, the second neutralization component can input waste liquid and drugs for neutralization reaction, and wait until the reaction is complete before the precipitate is completely settled to the bottom of the neutralization component. When the first neutralization component is completely discharged, the second neutralization component can discharge clear liquid and precipitate, achieving seamless connection of work and avoiding interruption of the treatment process. This alternating working mode also ensures the stable operation of the system. If a single component operates continuously for a long time, it is prone to wear and tear, failure and other problems, while the alternating operation of the two components can effectively distribute the working pressure and reduce equipment wear. Even if one component fails suddenly, another component can be put into use immediately, ensuring that wastewater treatment is not affected. Furthermore, it can further improve the effectiveness and efficiency of the neutralization reaction, helping the entire wastewater purification system operate more efficiently and stably, providing strong support for PCB printed circuit board manufacturers to achieve their green production goals.

[0041] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the neutralization device 3 includes a first neutralization component 31 and a second neutralization component 32. Both the first neutralization component 31 and the second neutralization component 32 are connected to the waste liquid component 1 and the dosing component 2. The first neutralization component 31 and the second neutralization component 32 are used to alternately receive waste liquid and drugs and alternately output clear liquid and precipitate. By connecting both the first neutralization component 31 and the second neutralization component 32 to the waste liquid component 1 and the dosing component 2, when the first neutralization component 31 is discharging clear liquid and precipitate, the second neutralization component 32 can input waste liquid and drugs for neutralization reaction. When the reaction is complete, the precipitate generated completely settles to the bottom of the second neutralization component 32. When the first neutralization component 31 is completely discharged, the second neutralization component 32 can discharge clear liquid and precipitate, achieving seamless operation, greatly improving processing efficiency, and reducing overall processing time. At the same time, this alternating working mechanism effectively ensures the stable operation of the system. A single neutralization component is prone to wear and tear and malfunction if it operates continuously for extended periods. However, by having two components work alternately, the workload is distributed, reducing equipment wear and extending its lifespan. Furthermore, if one component fails suddenly, the other can immediately take over, ensuring uninterrupted wastewater treatment and maintaining continuous system operation. In addition, the alternating operation of the two components allows the dosing component 2 to more precisely adjust the reagent delivery rate according to the reaction requirements of different amounts of wastewater, further improving the neutralization reaction's effectiveness and efficiency. This contributes to the efficient and stable operation of the entire wastewater purification system, providing a solid guarantee for green production in PCB (Printed Circuit Board) factories.

[0042] like Figure 6 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further defines: the first neutralization component 31 includes a first inlet 311, a first water tank assembly 312, and a first discharge assembly 313. One end of the first inlet 311 is disposed in the first water tank assembly 312, and the other end of the first inlet 311 is connected to the waste liquid assembly 1. One end of the first discharge assembly 313 is disposed in the first water tank assembly 312, and the other end of the first discharge assembly 313 is connected to an external system. The dosing assembly 2 is disposed on the first water tank assembly 312. The second neutralization component 32 includes a second inlet 321, a second water tank assembly 322, and a second discharge assembly 323. One end of the second inlet 321 is disposed in the second water tank assembly 322, and the other end of the second inlet 321 is connected to the waste liquid assembly 1. One end of the second discharge assembly 323 is disposed in the second water tank assembly 322, and the other end of the second discharge assembly 323 is connected to an external system. The dosing assembly 2 is disposed on the second water tank assembly 322. By connecting one end of the first inlet 311 of the first neutralization component 31 to the first water tank component 312 and the other end to the waste liquid component 1, the wastewater to be treated can be quickly introduced into the first water tank component 312. The dosing component 2 is installed on the first water tank component 312, allowing for precise addition of chemicals based on the actual condition of the wastewater, ensuring a thorough neutralization reaction within the first water tank component 312 and promoting the precipitation of pollutants such as metal ions. The first discharge component 313 then transports the clarified liquid and precipitate after the reaction to an external system, preparing for subsequent treatment. Similarly, the second inlet 321 of the second neutralization component 32, the second water tank component 322, and the second discharge component 323 work together to ensure the continuity of wastewater treatment. When the first neutralization component 31 is discharging clarified liquid and precipitate, the second neutralization component 32 can initiate a neutralization reaction in advance and wait for the precipitate to completely settle to the bottom of the second water tank component 322. Once switched, it can quickly begin operation, using the second discharge component 323 to discharge clarified liquid and precipitate, achieving seamless connection of the wastewater treatment process and greatly improving treatment efficiency. The first and second neutralization components, with their rational structural design, work in synergy with the entire wastewater purification system to effectively improve wastewater treatment efficiency and quality, reduce treatment costs, and minimize environmental pollution, providing strong support for PCB printed circuit board factories to achieve green and efficient production.

[0043] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first water tank assembly 312 includes a first water tank body 3121, a first sedimentation baffle 3122, a first stirrer 3123, and a first acid-base detector 3124; a first inlet 311, a first discharge assembly 313, and a dosing assembly 2 are disposed on the first water tank body 3121; the first sedimentation baffle 3122 and the first stirrer 3123 are disposed on two opposing inner sidewalls of the first water tank body 3121; and the first acid-base detector 3124 is disposed on the first water tank body 3121. By disposing of the first inlet 311, the first discharge assembly 313, and the dosing assembly 2 on the first water tank body 3121, the functions of introducing wastewater and chemicals and discharging treated liquid are respectively realized, ensuring the continuity of the neutralization process. The first sedimentation baffle 3122, disposed on the inner sidewall of the first water tank body 3121, can effectively promote the separation of sediment. During the neutralization reaction, it guides the rapid settling of precipitate, preventing it from flowing out with the clarified liquid, thus improving the purity of the clarified liquid and providing high-quality feed water for the subsequent purification system. The first stirrer 3123 rapidly stirs the wastewater and chemicals during the neutralization reaction, ensuring thorough mixing, accelerating the chemical reaction, and improving neutralization efficiency. The first acid-base detector 3124 monitors the acidity and alkalinity of the liquid in the tank in real time, providing accurate data support for the dosing assembly 2. Based on this data, the dosing assembly 2 adjusts the dosage of the reagent in a timely manner, ensuring that the neutralization reaction is always in the optimal acid-base environment, further improving the effectiveness and stability of the neutralization reaction.

[0044] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first discharge component 313 includes a first clear liquid discharge component 3131 and a first sediment discharge component 3132. One end of both the first clear liquid discharge component 3131 and the first sediment discharge component 3132 is disposed on the first water tank component 312, and the other end of both is connected to an external system. The first clear liquid discharge component 3131 is used to discharge clear liquid, and the first sediment discharge component 3132 is used to discharge sediment. By disposing of the first clear liquid discharge component 3131 and the first sediment discharge component 3132 on the first water tank component 312 respectively, with one end responsible for discharging clear liquid and the other end for discharging sediment, precise separation and discharge of clear liquid and sediment are achieved. After the neutralization reaction is completed, the first clear liquid discharge component 3131 can quickly transport the pure clear liquid to the external system, providing high-quality feed water for subsequent deep purification, reducing the burden of impurities in the clear liquid on the purification system, and improving the working efficiency of the purification system and the quality of the produced pure water. The first sediment discharge component 3132 can orderly discharge the sediment to the corresponding treatment stage, facilitating further treatment and recovery of impurities such as metals in the sediment. This precise discharge design avoids the mixing of the clarified liquid and the sediment, optimizes the subsequent treatment process, and improves the treatment effect of the entire wastewater purification system. The components of the first discharge component 313 work together in close coordination with other parts of the first neutralization component 31 and the entire wastewater purification system, ensuring the efficient and orderly operation of the wastewater treatment process.

[0045] like Figure 7 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the second water tank assembly 322 includes a second water tank body 3221, a second sedimentation baffle 3222, a second stirrer 3223, and a second acid-base detector 3224. The second inlet 321, the second outlet 323, and the dosing assembly 2 are disposed on the second water tank body 3221. The second sedimentation baffle 3222 and the second stirrer 3223 are disposed on two opposing inner sidewalls of the second water tank body 3221. The second acid-base detector 3224 is disposed on the second water tank body 3221. By disposing of the second inlet 321, the second outlet 323, and the dosing assembly 2 on the second water tank body 3221, the flow of wastewater input, treated liquid discharge, and reagent addition is ensured to be smooth. The second sedimentation baffle 3222 can accelerate sedimentation, allowing the clarified liquid to separate quickly from the sediment, preventing sediment from mixing with the clarified liquid, and providing high-quality influent for subsequent purification. The second agitator 3223 thoroughly mixes the wastewater and reagents, promoting rapid neutralization and improving treatment efficiency. The second acid-base detector 3224 monitors the pH level in real time, providing data support for the dosing assembly 2 to achieve precise dosing and ensure the neutralization reaction proceeds under optimal conditions. The second water tank assembly 322 works in conjunction with other components of the system, enhancing the overall wastewater purification system's processing capacity and stability, and helping the printed circuit board factory efficiently treat wastewater.

[0046] like Figure 7 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second discharge component 323 includes a second clear liquid discharge component 3231 and a second sediment discharge component 3232. One end of both the second clear liquid discharge component 3231 and the second sediment discharge component 3232 is disposed on the second water tank component 322, and the other end of both components is connected to an external system. The second clear liquid discharge component 3231 is used to discharge clear liquid, and the second sediment discharge component 3232 is used to discharge sediment. By connecting the second clear liquid discharge component 3231 and the second sediment discharge component 3232 to the second water tank component 322 and the external system respectively, precise separation and discharge of clear liquid and sediment are achieved. After the reaction is completed, the second clear liquid discharge component 3231 can quickly transport the pure clear liquid to the subsequent purification system, reducing the processing burden of the purification system and improving purification efficiency and the quality of pure water output. The second sediment discharge component 3232 discharges the sediment in an orderly manner to the corresponding links such as the reflux acid washing system, facilitating further processing and recovery of metal impurities in the sediment and avoiding mixing of clear liquid and sediment that could interfere with subsequent processes. This precise discharge design optimizes the connection between various links in the waste liquid purification system, improves the overall treatment effect, and works in conjunction with other components of the system to ensure that the wastewater treatment process is efficient and orderly.

[0047] like Figure 1 and Figure 2As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the waste liquid assembly 1 includes a waste liquid tank 11, a waste liquid output pipe 12, and a waste liquid control assembly 13. One end of the waste liquid output pipe 12 is disposed on the waste liquid tank 11, and the other end of the waste liquid output pipe 12 is connected to the neutralization device 3. The waste liquid control assembly 13 is disposed on the waste liquid output pipe 12. By connecting one end of the waste liquid output pipe 12 to the waste liquid tank 11 and the other end to the neutralization device 3, the wastewater stored in the waste liquid tank 11 is efficiently transported to the neutralization stage, initiating the subsequent treatment process. The waste liquid control assembly 13 disposed on the waste liquid output pipe 12 plays a crucial regulatory role. It can precisely control the output flow rate and velocity of the waste liquid according to the real-time processing capacity and demand of the neutralization device 3. When the system processing load is large, the waste liquid output velocity is appropriately reduced to avoid the neutralization device 3 from affecting the processing effect due to excessive processing volume; when the processing load is small, the waste liquid output volume is increased in a timely manner to fully utilize the equipment capacity and improve the overall processing efficiency. Through the effective regulation of the waste liquid control component 13, the wastewater is ensured to enter the neutralization device 3 stably and orderly, working closely with the entire waste liquid purification system to improve the stability and processing efficiency of the system operation.

[0048] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the waste liquid control component 13 includes a buffer 131, an overflow pipe 132, a waste liquid flow meter 133, and a waste liquid pump 134. The buffer 131, the waste liquid flow meter 133, and the waste liquid pump 134 are arranged on the waste liquid output pipe 12, and the overflow pipe 132 is arranged on the buffer 131. By arranging the waste liquid pump 134 on the waste liquid output pipe 12, power can be provided to ensure that the waste liquid is stably and continuously transported from the waste liquid tank 11 to the neutralization device 3, avoiding interruption of transport due to insufficient power and ensuring the continuity of the wastewater treatment process. The waste liquid flow meter 133 monitors the waste liquid flow in real time, providing accurate data for system control. Based on the flow data, the operator can flexibly adjust the operating parameters of the waste liquid pump 134 to match the waste liquid output with the processing capacity of the neutralization device 3, thereby improving the overall processing efficiency. The buffer 131 acts as a buffer and regulator, temporarily storing excess waste liquid when the waste liquid flow fluctuates, preventing sudden flow changes from impacting the neutralization device 3. The overflow pipe 132 connected to the buffer 131 provides protection for the waste liquid assembly 1. When the waste liquid level in the buffer 131 reaches a certain level, the overflow pipe 132 automatically opens, discharging the excess waste liquid and preventing damage to the buffer 131 due to excessive liquid level, thus ensuring safe system operation. The components of the waste liquid control assembly 13 work collaboratively with other components of the waste liquid assembly 1, ensuring stable and precise waste liquid delivery, laying a solid foundation for the efficient and stable operation of the entire system.

[0049] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the dosing assembly 2 includes a dosing tank 21, a dosing pipe 22, a dosing control assembly 23, and a dosing output assembly 24. The dosing pipe 22 is disposed on the dosing tank 21, the dosing control assembly 23 and the dosing output assembly 24 are disposed on the dosing pipe 22, and the dosing output assembly 24 is disposed on the neutralization device 3 and / or an external system. By connecting the dosing pipe 22 to the dosing tank 21, the drug can be delivered to subsequent stages. The dosing control assembly 23 is installed on the dosing pipe 22 and can precisely control the flow rate and velocity of the drug based on real-time data such as waste liquid composition, pH, and neutralization reaction progress. This ensures that the added drug meets the reaction requirements while avoiding excessive waste and reducing treatment costs. The dosing output component 24 is installed on the dosing pipeline 22 and connected to the neutralization device 3 and / or an external system. It accurately delivers precisely controlled reagents to the neutralization device 3, ensuring a complete neutralization reaction, effectively precipitating metal ions and other pollutants, and improving the neutralization effect. Connecting to an external system also allows for flexible handling of special dosing needs in different scenarios. All components of the dosing component 2 work collaboratively with other components of the wastewater purification system, providing strong support for the efficient and stable operation of the entire system and helping PCB printed circuit board manufacturers achieve high-quality wastewater treatment.

[0050] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the dosing control component 23 includes a dosing flow pump 231 and a dosing flow control valve 232, which are installed on the dosing pipeline 22. By installing the dosing flow pump 231 on the dosing pipeline 22 and the dosing flow control valve 232 on the same pipeline 22, stable and precise power can be provided, and the amount of reagent delivered can be precisely controlled based on the data fed back by the system. Whether the neutralization system requires a large amount of reagent to quickly adjust the pH, or a small amount of reagent is needed for fine-tuning in the later stages of the reaction, the dosing flow pump 231 can flexibly respond and ensure a stable supply of reagent. The two work together to enable the dosing system to accurately adapt to the needs of each treatment stage, maintain the optimal pH environment within the system, greatly improve the reaction effect and efficiency, and work closely with the entire waste liquid purification system.

[0051] like Figure 4 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the dosing output component 24 includes a first output component 241, a second output component 242, and a third output component 243. One end of each of the first output component 241, the second output component 242, and the third output component 243 is disposed on the dosing pipe 22. The other end of the first output component 241 and the second output component 242 is disposed on the neutralization device 3, and the other end of the third output component 243 is disposed on the external system. By connecting one end of the first output component 241 and the second output component 242 to the dosing pipe 22 and the other end to the neutralization device 3, the reagent can be precisely delivered according to the needs of different reaction zones within the neutralization device. When one of the neutralization components is outputting the precipitate and clear liquid after the neutralization reaction is completed, the reagent can be added to another neutralization component to carry out the neutralization reaction, ensuring that the neutralization system can proceed uninterruptedly and improving work efficiency. One end of the third output component 243 is connected to the dosing pipe 22, and the other end is connected to the external system, which can provide the desired acid-base environment for the external system and ensure that the external system can operate stably and normally.

[0052] Example 2

[0053] like Figures 1 to 10 As shown in the figure, this embodiment discloses a waste liquid purification system, including the above-mentioned neutralization system.

[0054] The second aspect of this application discloses a wastewater purification system. A neutralization system serves as a preparatory step for the wastewater purification process. Through precise addition of chemicals via a dosing system, the neutralization system effectively adjusts the pH of the wastewater. During this process, metal ions in the wastewater react chemically with the chemicals, separating from the wastewater and forming precipitates. On one hand, this removes the main pollutants from the wastewater, significantly reducing the burden on subsequent treatment processes and creating favorable conditions for the efficient operation of subsequent purification procedures. On the other hand, the effective separation of metal ions makes wastewater treatment more thorough, greatly reducing environmental pollution, lowering heavy metal emissions, and meeting environmental protection requirements.
