Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a Fenton-like electrolytic cell with a flow-guiding water distribution structure. Background Technology

[0002] With the continuous deepening and expansion of industrialization, new pollutants such as antibiotics and perfluorinated compounds, as well as high-concentration and difficult-to-degrade organic wastewater, have posed an unprecedented and serious threat to the aquatic environment. Due to their relatively low concentration, extremely strong toxicity, and difficulty in biodegradation, traditional wastewater treatment processes are inadequate in dealing with them, resulting in generally low removal efficiency. Fenton-like technology, as a highly efficient advanced oxidation technology, has emerged. This technology generates highly oxidizing hydroxyl radicals through catalytic reactions, which can effectively achieve the mineralization and decomposition of pollutants, thereby significantly improving the removal efficiency of pollutants and providing a new technical path for the treatment and protection of the water environment. Therefore, a Fenton-like electrolyzer with a flow-guiding water distribution structure is particularly needed.

[0003] Chinese patent CN219860736U, published on October 20, 2023, discloses an integrated bipolar Fenton electrolyzer device. This device allows for flexible adjustment of electrode area, operating current density, and the corresponding unit cell volume and number based on wastewater type and treatment requirements. Each unit cell operates at a low voltage, ensuring safety and reliability. However, this integrated bipolar Fenton electrolyzer device often employs a single water distribution method, resulting in uneven water distribution and significant variations in wastewater residence time on the electrode surface. This leads to incomplete reactions in some areas, low removal rates of new pollutants, and a lack of targeted flow field guidance structures. The low contact efficiency between wastewater and electrode active sites limits the reaction efficiency of in-situ generated hydrogen peroxide with catalytically active substances. Furthermore, the poor synergy between water distribution and turbulence structures prevents the formation of a stable circulating flow field, resulting in insufficient mass transfer efficiency during the reaction. This not only reduces degradation efficiency but also increases operating energy consumption and treatment costs. Additionally, some devices do not consider the connection between the water distribution system and the deep treatment unit, easily causing fine particulate matter accumulation and affecting the service life of subsequent filtration devices. Utility Model Content

[0004] The purpose of this invention is to provide a Fenton-like electrolyzer with a flow-guiding water distribution structure to solve the problems mentioned in the background art. Existing integrated bipolar Fenton electrolyzer devices often use a single water distribution method, resulting in uneven water distribution, large differences in wastewater residence time on the electrode surface, incomplete reaction in some areas, low removal rate of new pollutants, lack of targeted flow field guiding structure, low contact efficiency between wastewater and electrode active sites, limiting the reaction efficiency of in-situ generated hydrogen peroxide and catalytically active substances. Furthermore, the poor synergy between water distribution and turbulence structures prevents the formation of a stable circulating flow field, leading to insufficient mass transfer efficiency during the reaction. This not only reduces degradation efficiency but also increases operating energy consumption and treatment costs. In addition, some devices do not consider the connection between the water distribution system and the deep treatment unit, easily causing the accumulation of fine particles and affecting the service life of subsequent filtration devices.

[0012] Compared with existing technologies, the beneficial effects of this utility model are as follows: This Fenton-like electrolyzer with a flow-guiding water distribution structure constructs a three-stage water distribution system consisting of main pipe diversion, arc-shaped water distribution, and annular distribution holes by setting up flow-guiding water distribution components. The multi-component diversion pipes, together with the arc-shaped flow-guiding water distribution plate, can uniformly guide wastewater to various areas of the electrolyzer. The annularly distributed water distribution holes further realize the gradient diffusion of water flow, avoiding the problems of local reaction blanks or concentrated water flow scouring the electrodes caused by traditional water distribution. At the same time, the staggered inclined baffles and the flow-guiding water distribution form a synergistic flow field, prolonging the residence time of wastewater on the electrode surface, and allowing the wastewater to fully contact the hydrogen peroxide generated in situ at the cathode and the catalytic active sites at the anode. Mass transfer efficiency is improved. The loading substrate of the anode unit is optimized to combine electrocatalytic oxidation and Fenton-like catalysis, which can promote iron ion circulation. The bimetallic catalytic frame of the cathode unit enhances the in-situ hydrogen peroxide production efficiency, eliminating the need for continuous addition of hydrogen peroxide and soluble metal ions, thus reducing operating costs. The heating rod and temperature sensor work together to stably control the reaction temperature within a suitable range, adapting to the reaction requirements of different water qualities. The aeration disc and aeration blower work together to provide sufficient oxygen, ensuring the in-situ hydrogen production efficiency of the cathode.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5This utility model provides a technical solution: a Fenton-like electrolyzer with a flow-guiding water distribution structure, including a Fenton-like electrolyzer body 1, an inclined plate 2 fixedly installed at the bottom inside the Fenton-like electrolyzer body 1, an installation hole 3 and a through hole 4 on the outer side of the Fenton-like electrolyzer body 1, a top cover 5 fixedly installed on the top of the Fenton-like electrolyzer body 1, an exhaust port 6 on the top of the top cover 5, and a pull ring 7 fixedly installed on the top of the top cover 5. A flow-guiding water distribution assembly 8 is provided inside the Fenton-like electrolyzer body 1; the flow-guiding water distribution assembly 8 includes a fixing seat 801, which is installed on... Inside the Fenton-like electrolyzer body 1, an anode unit 802 is fixedly installed on the outside of a fixing base 801. A load base 803 is fixedly installed at the bottom of the anode unit 802. A connecting column 804 is fixedly installed on the outside of the anode unit 802. A partition 805 is fixedly installed inside the Fenton-like electrolyzer body 1. A baffle 806 is fixedly installed on the outside of the partition 805. A water distribution main pipe 807 is provided inside the Fenton-like electrolyzer body 1. A diversion pipe 808 is connected through the outside of the water distribution main pipe 807. A guide water distribution plate 809 is provided on the outside of the diversion pipe 808. A water distribution hole 810 is opened on the top of the guide water distribution plate 809.

[0021] Furthermore, the flow-guiding water distribution assembly 8 also includes a cathode unit 811, which is installed inside the Fenton-like electrolyzer body 1. A bimetallic catalyst frame 812 is fixedly installed inside the cathode unit 811, and a heating rod 813 is fixedly installed at the bottom of the cathode unit 811. A protective frame 814 is fixedly installed inside the Fenton-like electrolyzer body 1, an aeration disc 815 is provided on the outside of the protective frame 814, an aeration fan 816 is provided on the inside of the protective frame 814, a temperature sensor 817 is fixedly installed inside the Fenton-like electrolyzer body 1, and a filter plate 818 is fixedly installed inside the Fenton-like electrolyzer body 1. The unit is equipped with a sludge outlet pipe 819. By setting up a flow-guiding water distribution component 8, a three-stage water distribution system is constructed, consisting of main pipe diversion, arc-shaped water distribution, and annular distribution holes. The multi-component diversion pipe 808, together with the arc-shaped flow-guiding water distribution plate 809, can uniformly guide the wastewater to various areas of the electrolyzer. The annularly distributed water distribution holes 810 further realize the gradient diffusion of the water flow, avoiding the problems of local reaction blanks or concentrated water flow scouring the electrodes caused by traditional water distribution. At the same time, the staggered inclined baffles 806 form a synergistic flow field with the flow-guiding water distribution, prolonging the residence time of the wastewater on the electrode surface, so that the wastewater can fully contact the hydrogen peroxide generated in situ at the cathode and the catalytic active sites at the anode, thereby improving the mass transfer efficiency.

[0022] Furthermore, mounting holes 3 are adapted to the main water distribution pipe 807, and multiple sets of through holes 4 and sludge outlet pipe 819 are provided, with each set of through holes 4 corresponding to and adapted to the sludge outlet pipe 819. By setting mounting holes 3 to the main water distribution pipe 807 and through holes 4 to the sludge outlet pipe 819, precise connection and installation of the water distribution system and the sludge discharge system are achieved. Mounting holes 3 provide stable positioning support for the main water distribution pipe 807, preventing pipe displacement due to water flow impact during water distribution and ensuring water distribution stability. Multiple sets of one-to-one corresponding through holes 4 and sludge outlet pipe 819 can simultaneously discharge sludge from different areas in the electrolytic cell, avoiding local sludge accumulation. Combined with the sludge guiding effect of the inclined plate 2, sludge discharge efficiency is significantly improved. This adaptability design simplifies the equipment assembly process, achieving a tight connection between the pipe and the tank without additional welding or sealing, reducing installation difficulty, and facilitating subsequent pipe disassembly, maintenance, and replacement, thus meeting the needs of continuous industrial operation.

[0023] Furthermore, multiple identical sets of fixed bases 801, anode units 802, and load substrates 803 are provided, and two sets of anode units 802 are fixedly connected by connecting columns 804. By setting up fixed bases 801, anode units 802, and load substrates 803, multiple sets of fixed bases 801 provide uniform support for anode units 802, ensuring that the anode units 802 are stably distributed in the electrolytic cell and avoiding displacement due to water flow impact or electrode reactions. The load substrate 803 is optimized to have both electrocatalytic oxidation and Fenton-like catalysis functions, which can promote iron ion circulation and enhance the degradation efficiency of pollutants. The connecting columns 804 realize the synergistic linkage of multiple sets of anode units 802, forming a uniform electric field distribution and improving current utilization efficiency. The distributed layout of multiple sets of anode units 802 and the cathode unit 811 form a high-efficiency reaction area, which greatly improves the simultaneous removal effect of new pollutants and conventional pollutants. Moreover, the modular design makes it easy to flexibly adjust the number of anode units 802 according to the wastewater treatment volume and adapt to different treatment scale requirements.

[0024] Furthermore, the horizontal cross-section of the baffle 806 is inclined, and multiple sets of baffles 806 are arranged in an alternating pattern. By setting the baffles 806, the inclined structure of the baffles 806 can guide the water flow to form an upward lift force. Combined with the water distribution direction of the guide water distribution plate 809, a stable vertical circulation flow is constructed in the electrolytic cell, which prolongs the residence time of wastewater on the electrode surface. This allows the wastewater to fully contact and react with the hydrogen peroxide generated in situ at the cathode and the catalytic active sites at the anode, avoiding the problem of insufficient reaction caused by short-flow water in traditional equipment. The alternating layout can break the laminar flow state of the water, enhance the degree of water turbulence, improve mass transfer efficiency, and make the catalytic reaction more uniform and thorough. At the same time, the baffles 806 can also prevent the particulate matter generated by the reaction from floating to the surface and guide it to settle towards the bottom inclined plate 2. Combined with the sludge discharge system, this achieves efficient separation of particulate matter, reduces the adhesion and contamination of the electrode surface, and extends the service life of the electrode.

[0025] Furthermore, the diversion pipe 808 is provided with multiple identical sets, the guide water distribution plate 809 has an arc-shaped structure, and the water distribution holes 810 are provided with multiple identical sets. The multiple sets of water distribution holes 810 are located on the outside of the guide water distribution plate 809 and are distributed in a ring. By setting the guide water distribution plate 809, the arc-shaped structure can evenly diffuse the wastewater transported by the diversion pipe 808 along the arc surface, avoiding the water flow directly hitting the electrode and causing local scouring and wear. The multiple sets of water distribution holes 810 distributed in a ring realize the gradient distribution of water flow, ensuring that the wastewater evenly covers each reaction area of ​​the electrolyzer, eliminating local reaction blank areas, and greatly improving the reaction uniformity. The combination of multiple sets of diversion pipes 808 and guide water distribution plate 809 can flexibly adjust the water distribution points according to the size of the electrolyzer, adapting to the needs of different specifications of equipment. Combined with the flow field optimization effect of the baffle 806, the mass transfer efficiency is improved, and the pollutant degradation effect is significantly enhanced.

[0026] Furthermore, multiple sets of heating rods 813 are provided, and these sets of heating rods 813 are equidistantly distributed at the bottom of the cathode unit 811. The filter plate 818 is tightly fitted with the sludge outlet pipe 819. By setting multiple sets of heating rods 813 and filter plates 818 and sludge outlet pipe 819, the equidistantly distributed heating rods 813 can achieve uniform temperature control within the electrolytic cell. With the real-time monitoring of the temperature sensor 817, the reaction temperature is stably controlled within a suitable range, ensuring the efficient conduct of the Fenton-like reaction and adapting to the reaction requirements of different water qualities. The tight fit between the filter plate 818 and the sludge outlet pipe 819 can efficiently trap fine particles and a small amount of sludge generated during the reaction, preventing them from entering the sludge outlet pipe 819 and causing pipe blockage, thus extending the service life of the sludge discharge system. At the same time, the filter plate 818 can also prevent particles from adhering to the electrode surface and affecting catalytic activity. Combined with the sludge guiding effect of the inclined plate 2 and the synchronous sludge discharge of multiple sets of sludge outlet pipes 819, the sludge can be quickly and thoroughly removed, reducing the frequency and cost of equipment maintenance and improving long-term operational stability.

[0027] Working Principle: First, the operator selects a corrosion-resistant material to process the rectangular electrolytic cell body. An inclined plate 2 is fixedly installed at the bottom inside to ensure sludge can collect downwards along the plate surface. Multiple sets of mounting holes 3 and through holes 4 are pre-set on the outside of the electrolytic cell body. The mounting holes 3 must be precisely matched to the dimensions of the water distribution main pipe 807. The top cover 5 is fixed to the top of the electrolytic cell body with bolts. An exhaust port 6 is reserved on the top of the top cover 5 to discharge the gases generated during the reaction. Simultaneously, pull rings 7 are symmetrically installed on the top of the top cover 5 for easy opening and maintenance. The sealing of each connection point is checked to ensure no leakage. Multiple sets of anode units 802 are fixed inside the electrolytic cell body via fixing seats 801. The load base 803 at the bottom of the anode unit 802 must be parallel to the bottom of the electrolytic cell. Two sets of anode units 802 are connected via... A connecting column 804 is fixedly connected to ensure uniform electric field distribution. A cathode unit 811 is installed at the corresponding position inside the electrolytic cell. A bimetallic catalyst frame 812 is fixed inside the cathode unit 811. The water distribution main pipe 807 is inserted into the electrolytic cell body through the mounting hole 3. Multiple branch pipes 808 are connected to the outside of the water distribution main pipe 807. An arc-shaped guide water distribution plate 809 is installed at the end of the branch pipe 808. Multiple sets of annularly distributed water distribution holes 810 are opened on the top of the guide water distribution plate 809 to ensure that the water flow can be evenly diffused along the arc-shaped plate surface. Multiple sets of inclined baffles 806 are fixed inside the electrolytic cell body through a partition 805, and adjacent sets of baffles 806 are staggered to ensure that a stable upper and lower circulating flow field can be constructed. Multiple sets of heating rods 813 are installed at equal intervals at the bottom of the cathode unit 811. Simultaneously, a temperature sensor 817 is fixed inside the electrolytic cell body, and the two are connected to an external temperature controller via wires. A protective frame 814 is fixed inside the electrolytic cell body, and an aeration disc 815 is installed on the outside of the protective frame 814. An aeration fan 816 is installed inside the frame. The aeration disc uses a microporous structure. A filter plate 818 is fixed inside the electrolytic cell body near the sludge collection area. The filter plate 818 is tightly fitted with the sludge outlet pipe 819. The sludge outlet pipe 819 is passed through the through hole 4 out of the electrolytic cell body to ensure that each outlet pipe is accurately connected to the external sludge discharge pipeline. The external power supply is connected, and the conductivity of the anode unit 802 and the cathode unit 811 is tested to ensure uniform electric field strength. The water distribution system is started, and the water distribution uniformity of the guide water distribution disc 809 is checked. There is no local water flow concentration. Aeration is then turned on. The system ensures uniform bubble distribution, closes exhaust port 6, and sends the wastewater to be treated through a screen to remove suspended solids into a homogenization and equalization tank to ensure the water quality meets reaction requirements. Based on the wastewater treatment volume, wastewater is injected into the electrolytic cell through the main water distribution pipe 807. The aeration blower 816 is turned on, and air is introduced into the electrolytic cell through the aeration disc 815. The temperature control system is activated, and the heating rod 813 and temperature sensor 817 work together to maintain a stable temperature. The DC power supply is connected, and the water distribution system evenly distributes the wastewater into the electrolytic cell through the annular water distribution holes 810 of the guide water distribution disc 809. The staggered baffles 806 guide the water flow to form an up-and-down circulating flow, extending the residence time of the wastewater on the electrode surface and ensuring sufficient contact between the wastewater and the hydrogen peroxide generated in situ at the cathode and the catalytic active sites at the anode.The temperature and pollutant concentration inside the electrolytic cell are monitored in real time. After the reaction, the wastewater is filtered by filter plate 818 to remove fine particles and then discharged from the outlet of the electrolytic cell. It then enters the subsequent activated carbon adsorption column or ultrafiltration membrane module for further treatment to ensure that the effluent meets discharge standards or is reused. The sludge generated during the reaction is guided by inclined plate 2 to collect at the bottom of the cell and discharged simultaneously through multiple sludge outlet pipes 819. After the sludge is discharged, clean water is injected through the water distribution system to rinse the electrolytic cell to prevent sludge residue from clogging the water distribution holes 810 or adhering to the electrode surface. After treatment, the DC power supply is turned off first, and then the aeration blower and heating rod 813 are stopped. After the temperature inside the electrolytic cell drops to room temperature, the residual wastewater and sludge in the cell are drained. The top cover 5 is opened through pull ring 7 to check whether there are pollutants adhering to the surface of the anode unit 802 and the cathode unit 811. If any faults are found, they are replaced in time. After maintenance, the equipment is reassembled and put on standby.
