Description

Technical Field

[0001] This utility model relates to the field of organic wastewater treatment technology, specifically to a novel magnetic field-hydraulic coupling recovery device. Background Technology

[0002] Organic wastewater is wastewater primarily composed of organic pollutants. It easily leads to eutrophication, posing a significant health hazard. Organic wastewater generally refers to wastewater with a concentration of 2000 mg / L or higher discharged from industries such as papermaking, leather, and food processing.

[0003] In practical industrial wastewater treatment, nano- or micron-sized heterogeneous catalysts are easily lost with the effluent due to their small particle size, resulting in material waste and potential environmental risks. Currently used static magnetic field recovery methods have significant limitations. Magnetic particles tend to form magnetic chain agglomerates under the influence of a magnetic field, leading to a decrease in specific surface area and consequently affecting catalytic performance. Furthermore, they have low capture efficiency for catalysts in deep suspension. Meanwhile, industrial wastewater often involves complex conditions such as high flow rates, strong shear forces, salinity, and organic matter, placing higher demands on catalyst recovery. However, existing technologies mostly focus on the structural modification of the catalytic material itself, lacking synergistic design and integration schemes with process intensification equipment, making it difficult to simultaneously achieve the unified goals of efficient catalysis and green recovery. Therefore, we propose a novel magnetic field-hydraulic coupling recovery device. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Please see Figure 1 - Figure 4 This utility model provides a novel magnetic field-hydraulic coupling recovery device, comprising:

[0028] The coupled reaction chamber 1 utilizes fluid dynamics optimization to create high-speed mixing in the reaction zone and low-speed vortices in the magnetic capture zone, which is beneficial for particle sedimentation and capture and prevents external contamination.

[0029] Magnetic field unit 2 uses a double-layer water-cooled electromagnetic coil, which can dynamically adjust the magnetic induction intensity from 0 to 0.3T to generate a gradient magnetic field and enhance the capture efficiency of magnetic particles.

[0030] The hydraulic unit 3 includes a variable frequency centrifugal pump 31 and a spiral guide 32. The variable frequency centrifugal pump 31 and the spiral guide 32 form a controllable shear field, and the fluid motion is optimized by adjusting the flow rate and velocity.

[0031] The intelligent control unit 4 intelligently adjusts the magnetic field strength and pump speed based on real-time detection signals to achieve dynamic matching of the magnetic-hydraulic field, monitor and adjust operating parameters in real time, and improve recovery efficiency and stability.

[0032] In this embodiment, preferably, a top cover 5 is detachably installed on the upper end of the coupling reaction chamber 1, and a hopper 6 is installed inside the right side of the top cover 5. A water discharge pipe 7 is installed on the lower right side of the coupling reaction chamber 1, and the water discharge pipe 7 is equipped with a control valve.

[0033] The hopper 6 is designed with a funnel-shaped structure to facilitate the uniform addition of materials to be treated. The control valve of the discharge pipe 7 adopts an electric adjustment mode and can be connected to the intelligent control unit 4 to realize automatic opening and closing and fine flow control based on liquid level or turbidity detection, ensuring efficient and stable discharge process. The discharge pipe 7 is used to discharge the treated fluid.

[0034] In this embodiment, preferably, the magnetic field unit 2 further includes a temperature sensor. The temperature sensor is embedded inside or near the double-layer water-cooled electromagnetic coil for real-time monitoring of the coil's operating temperature. The monitoring data is transmitted to the intelligent control unit 4 via a signal line to achieve automatic adjustment based on a temperature threshold. When the temperature exceeds the set safe range, the intelligent control unit 4 can automatically reduce the magnetic field strength or increase the water cooling flow rate, effectively preventing the coil from overheating and being damaged. This ensures that the dynamic adjustment process of the 0-0.3T magnetic induction intensity is stable and reliable, improving the safety and durability of the device operation.

[0035] In this embodiment, preferably, the variable frequency centrifugal pump 31 is equipped with a flow meter to precisely control the flow rate between 0.5-10 m / s. 3 Within the range of / h. The flow meter is preferably an electromagnetic flow meter, whose output signal is transmitted to the intelligent control unit 4 via a signal line to achieve automatic closed-loop control based on preset flow velocity parameters; when the detected flow velocity deviates by 0.5-10m... 3 When the speed is within the range of / h, the intelligent control unit 4 can adjust the speed of the variable frequency centrifugal pump 31 in real time to ensure that the hydraulic conditions are accurately matched with the material processing requirements, thereby improving the response speed and energy efficiency ratio of the device operation.

[0036] In this embodiment, preferably, the coupling reaction chamber 1 is equipped with a pH sensor, a turbidity sensor, an electromagnetic field intensity probe, and a central controller connected to each sensor. The central controller receives monitoring signals from the pH sensor, turbidity sensor, and electromagnetic field intensity probe in real time, realizing automatic closed-loop control based on preset parameters. When the pH value deviates from the set range, the central controller can automatically adjust the amount of acid or alkali added. When the turbidity exceeds the threshold, a cleaning or flow rate optimization mechanism is triggered. When the electromagnetic field intensity fluctuation exceeds the safe range, the central controller, in conjunction with the intelligent control unit 4, dynamically adjusts the magnetic field strength or hydraulic conditions to ensure efficient and stable reaction process, improve material recovery rate, and enhance the reliability of device operation.

[0037] In this embodiment, preferably, the intelligent control unit 4 integrates a data storage unit, a self-cleaning mechanism, and a safety interlock device. The data storage unit records in real-time the operating parameters of the variable frequency centrifugal pump 31, the monitoring values ​​of each sensor, and the control command execution log, forming a historical operating database for easy retrospective analysis and process optimization. The self-cleaning mechanism automatically initiates the flushing procedure of the pipeline and the coupling reaction chamber 1 based on feedback from the turbidity sensor or preset periodic commands to prevent scaling and blockage. The safety interlock device monitors the status of key system nodes in real-time; when it detects abnormal pressure changes, overload current, or exceeding safety parameter limits, it immediately triggers equipment shutdown protection and issues an alarm, while simultaneously locking the current operating permissions in conjunction with the central controller.

[0038] In this embodiment, preferably, a shock-absorbing bracket is also included below the coupling reaction chamber 1. The shock-absorbing bracket consists of a support cylinder 8 and support columns 9 arranged circumferentially on the outer circumference of the support cylinder 8. The shock-absorbing bracket is used to absorb mechanical vibration and external impact during operation. The support cylinder 8 adopts a carbon steel structure with a shock-absorbing rubber lining. The support columns 9 are distributed at 90-degree intervals and embedded in anti-slip bases to ensure the overall rigidity and horizontal stability of the device and reduce interference with the fluid dynamics within the coupling reaction chamber 1.

[0039] Working principle and usage process of this utility model:

[0040] During operation, wastewater enters the chamber from top to bottom via a variable frequency centrifugal pump 31, while the magnetic catalyst mixture enters from top to bottom via a hopper 6. Flowing through the inlet area of ​​the coupled reaction chamber 1, it is guided by a spiral guide 32 to form a high-speed mixing flow field, promoting full contact and reaction between the wastewater and the magnetic catalyst. The fluid enters the magnetic capture zone, where, under the action of a low-speed vortex and combined with the gradient magnetic field generated by the magnetic field unit 2, magnetic particles are efficiently captured and settle to the bottom of the chamber. The treated clarified fluid is automatically discharged through the discharge pipe 7, with the flow rate precisely controlled by the intelligent control unit 4 based on the turbidity sensor signal. Simultaneously, the central controller monitors the pH value, turbidity, and electromagnetic field strength in real time, dynamically adjusting the addition of acid / alkali agents, pump speed, or magnetic field strength to ensure maximum recovery efficiency. Finally, the settled particles are periodically removed through a bottom valve, and the device completes the rinsing cycle through a self-cleaning mechanism, ensuring continuous and stable operation. After shearing and mixing, the particles react fully and are then rapidly enriched and separated under the action of the lower magnetic field. The control module can intelligently adjust the magnetic field strength and pump speed based on real-time detection signals (such as turbidity, ORP, conductivity, etc.) to achieve dynamic matching of the magnetic and hydraulic fields, thereby improving recovery efficiency and reducing energy consumption.

[0041] With its modular design, it can be flexibly embedded into existing wastewater treatment systems without major modifications; its pulsed magnetic flux and synergistic flow field mechanism significantly improves recovery efficiency, and it is especially suitable for the recovery of magnetic materials in catalytic degradation processes, with broad engineering application prospects.
