Description

Technical Field

[0001] This utility model relates to an electrolytic device for the degradation of organic matter in wastewater, belonging to the field of organic matter degradation technology. Background Technology

[0002] With the increasing variety of pollutants in industrial wastewater, including more persistent organic pollutants and toxic and harmful pollutants, direct discharge of these pollutants without effective treatment will severely pollute water bodies, soil, and the atmosphere, disrupting ecosystem balance and even entering the human body through the food chain, causing chronic poisoning, cancer, and other serious diseases, thus endangering public health. This poses an irreversible and serious threat to the natural environment and human health.

[0003] Currently, industrial wastewater treatment technologies mainly include biological treatment, physicochemical treatment, and membrane separation technology. Although these technologies have solved some pollution problems to a certain extent, they still have shortcomings such as low treatment efficiency, high cost, and complex operation. Selecting the appropriate process to treat the corresponding industrial wastewater is of paramount importance. Electrolysis has the advantages of simple process, wide application range, and good treatment effect. It has significant advantages over other processes in treating industrial wastewater with high salinity, high COD concentration, poor biodegradability, and high color. Treatment of poor biodegradability wastewater by electrolysis can greatly improve its biodegradability, which is beneficial to the improvement of subsequent biological treatment effects. Currently, this process is generally used for the pretreatment of poor biodegradability organic wastewater from pharmaceuticals, printing and dyeing, leather making, and petrochemicals, or in combination with other processes to achieve the goals of improving biodegradability, decolorization, and reducing toxicity.

[0004] Traditional waste liquid organic matter degradation devices have certain limitations in terms of treatment efficiency and exhaust emissions, making it difficult to achieve efficient and thorough organic matter degradation. In particular, during the electrolysis process, how to effectively seal the electrolytic cell, ensure the stable connection of conductive joints, and deal with the generated acid mist remain pressing problems that need to be solved in existing technologies.

It has the advantages of high treatment efficiency, stable structure, and effective sealing of the electrolytic cell.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] An electrolytic device for the degradation of organic matter in wastewater includes an insulated electrolytic cell 1 and an insulated sealing cover 12.

Detailed Implementation

[0023] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] Existing industrial wastewater treatment technologies suffer from low treatment efficiency, complex operation, and high costs. Traditional electrolysis devices employ a single electrode layout, resulting in insufficient electrolyte flow during electrolysis and inadequate contact time between organic matter and the electrode. Furthermore, the device has poor sealing performance, allowing harmful gases generated during electrolysis to escape and cause secondary pollution. The fixed electrode installation structure makes replacement and maintenance difficult, affecting the long-term stable operation of the equipment.

[0025] To address the aforementioned issues, and considering the advantages of electrolysis in treating high-salinity, recalcitrant wastewater, the electrolytic cell structure design needs to be optimized to improve treatment efficiency. Analysis of the impact of electrode layout on current distribution reveals that alternating multi-layer arrangements can increase the effective reaction area. To address the issue of harmful gas escape, a solution to enhance the electrolytic cell's sealing is proposed. To solve the problem of inconvenient electrode maintenance, a sliding installation structure design is adopted. Combining fluid mechanics principles, the positions of the inlet and outlet are optimized to promote sufficient wastewater flow.

[0026] This application discloses an electrolytic device for the degradation of organic matter in wastewater, comprising an insulated electrolytic cell 1 and an insulated sealing cover 12. The four sides of the electrolytic cell 1 are sequentially connected as side A, side B, side C, and side D. The sealing cover 12 is provided on side A of the electrolytic cell 1. Several layers of electrode slots are horizontally arranged on the inner walls of sides B and D of the electrolytic cell 1. The electrode slots include titanium anode slots 6 and stainless steel cathode slots 7, which are alternately arranged and have the lowest possible density. Both the lower electrode slot and the top electrode slot are titanium anode slots 6. A titanium-based anode plate 2 is horizontally slidable inside the titanium anode slot 6. A stainless steel cathode plate 3 is horizontally slidable inside the stainless steel cathode slot 7. The positive electrode of the external power supply device 10 is connected to the titanium anode slot 6 on the side of the electrolytic cell 1D, and the negative electrode of the external power supply device 10 is connected to the stainless steel cathode slot 7 on the side of the electrolytic cell 1D. An inlet 4 is provided at the bottom of the electrolytic cell 1, and an inlet pipe is connected to the inlet 4. An outlet 5 is provided at the top of the electrolytic cell 1, and an outlet pipe is connected to the outlet.

[0027] Among them, the titanium anode slot refers to the conductive bracket used to limit and fix the titanium-based anode plate, which can be made of titanium alloy material, and has corrosion resistance and conductivity stability; the stainless steel cathode slot refers to the conductive bracket used to fix the cathode plate, which enhances the structural strength while maintaining conductivity; the horizontal sliding installation method refers to the assembly structure in which the electrode plate is inserted into the slot in a horizontal direction, and a conductive guide strip can be set in the slot to achieve smooth sliding; the upper and lower convection design of the liquid inlet and outlet refers to the flow path of liquid entering from the bottom and exiting from the top, which can be achieved by setting a gradually expanding water inlet channel to achieve uniform water distribution.

[0028] Specifically, the electrolytic cell forms a closed cavity through a sealing cover on side A, which can be removed for electrode replacement during maintenance. Multi-layered electrode slots (alternating titanium anode slots 6 and stainless steel cathode slots 7) on sides B and D form a vertically staggered electrode layout. When the anode and cathode plates are inserted into their corresponding slots, a multi-layered alternating electrode array is formed. The power supply unit supplies power to the electrodes through the slots on side D, creating an electric field perpendicular to the liquid flow direction. Wastewater enters from the bottom inlet and flows upwards, passing sequentially through the gaps between each electrode layer. Gases generated during electrolysis are blocked by the sealed structure and treated through a dedicated exhaust channel. The horizontal sliding structure of the electrode plates facilitates replacement; maintenance only requires opening the sealing cover and removing the old electrode.

[0029] This scheme increases the effective electrolysis area by multiple times within the same volume through a vertically arranged, multi-layered alternating arrangement of anode and cathode electrodes. Traditional devices often use a side-to-center inlet, which can easily create flow dead zones. This scheme's vertical convection design ensures uniform liquid flow through all electrode layers. This application achieves highly efficient electrochemical degradation of organic matter in wastewater. The multi-layered electrode layout extends the residence time of pollutants in the electric field, enhancing the electrolytic degradation reaction. The sealed structure effectively prevents the leakage of harmful gases, reducing environmental risks. The sliding electrode design simplifies maintenance and improves the continuity of equipment operation. The vertical convection liquid distribution avoids electrode passivation caused by excessively high local concentrations, ensuring the stability of treatment efficiency.

[0030] This application further proposes that a titanium anode conductive connector and a stainless steel cathode conductive connector are embedded inside the side of the electrolytic cell 1D. The two ends of the titanium anode conductive connector are A and B, respectively. The A end of the anode conductive connector is connected to the titanium anode slot 6 on the side of the electrolytic cell 1D, and the B end of the anode conductive connector is connected to the positive terminal of the external power supply device 10 through the anode titanium-coated copper conductive rod 8. The two ends of the stainless steel cathode conductive connector are A' and B', respectively. The A' end of the stainless steel cathode conductive connector is connected to the stainless steel cathode slot 7 on the side of the electrolytic cell 1D, and the B' end of the stainless steel cathode conductive connector is connected to the negative terminal of the external power supply device 10 through the stainless steel-coated copper conductive rod 9.

[0031] Among them, the titanium anode conductive connector refers to a conductive component embedded inside the side D of the electrolytic cell, with a material matching the anode slot. Specifically, it can be implemented using a one-piece molded titanium alloy component. Its A end forms a gapless connection with the titanium anode slot via mechanical snap-fit, and its B end can be equipped with a threaded interface for fixing the titanium-clad copper conductive rod. The stainless steel cathode conductive connector refers to a conductive component embedded inside the side D of the electrolytic cell, with a material consistent with the cathode slot. Its A' end can form a continuous conductive path with the stainless steel cathode slot via welding, and its B' end can be equipped with a threaded structure or a flange structure for fixing the stainless steel-clad copper conductive rod. The anode titanium-clad copper conductive rod refers to a commercially available composite conductor with an outer layer of titanium and an inner copper core. Specifically, the titanium layer can be coated onto the surface of the copper core using an explosive welding process. The copper core is used to transmit large currents, and the titanium layer is used to isolate the copper core from electrolyte corrosion. The stainless steel-clad copper conductive rod refers to a commercially available composite conductor with an outer layer of stainless steel and an inner copper core. Specifically, the stainless steel and copper core can be combined using a hot-pressing composite process. The copper core improves conductivity, and the stainless steel layer prevents electrolyte corrosion and mechanical wear.

[0032] Specifically, the A end of the titanium anode conductive connector is directly connected to the titanium anode slot. Both are made of the same material and have no dissimilar metals at the contact surface, eliminating the increase in interface resistance caused by electrochemical corrosion. Its B end is connected to the positive terminal of the power supply via a titanium-clad copper conductive rod. The copper core performs the main conductive function, while the titanium layer protects the copper core from electrolyte corrosion. The A' end of the stainless steel cathode conductive connector is welded to the stainless steel cathode slot to form an integral conductive path, avoiding poor contact caused by vibration. Its B' end is connected to the negative terminal of the power supply via a stainless steel-clad copper conductive rod. The stainless steel outer layer maintains corrosion resistance while the copper core reduces the overall resistance. These two types of conductive connectors, through differentiated material combinations and connection structures, are adapted to the operating conditions of the strong oxidizing environment in the anode region and the reducing environment in the cathode region, respectively, simultaneously improving the conductivity and corrosion resistance of the current transmission path.

[0033] Existing electrolysis devices typically employ external conductive connectors, which are susceptible to corrosion when exposed to the electrolyte environment, leading to increased contact resistance and unstable power supply. Alternatively, they may use a single metal conductive rod, failing to simultaneously meet conductivity and corrosion resistance requirements. This solution, however, integrates the conductive connector into the sidewall of the electrolytic cell, forming a unified structure with the slot, thus isolating the connection interface from direct electrolyte corrosion. It utilizes composite conductive rods made of titanium-clad copper and stainless steel-clad copper, respectively matching the corrosion resistance requirements of the anode and cathode in key conductive areas. Simultaneously, the copper core enhances current-carrying capacity, resolving the technical contradiction between dissimilar metal contact corrosion and the single performance of the conductive medium in traditional devices. This application achieves efficient and stable connection between the anode and cathode conductive connectors and the external power supply in the electrolysis device. Material matching eliminates energy loss caused by interface corrosion, and the composite conductive rod structure simultaneously improves conductivity and corrosion resistance, thereby ensuring the stability of high-current transmission and extending the service life of key conductive components.

[0034] This application further proposes that an acid mist exhaust hole 11 is opened in the center of the top plate of the electrolytic cell 1, and the acid mist exhaust hole 11 is connected to an acid mist purification device through an acid mist exhaust pipe.

[0035] The acid mist exhaust vent refers to a circular or rectangular channel located at the center of the top surface of the electrolytic cell. It can be manufactured using mechanical drilling or stamping processes. The location of this vent is designed based on the natural upward flow of gas, enabling the concentrated collection of acidic volatile gases generated during the electrolysis reaction. The acid mist purification device is used to neutralize and treat acidic gases. It can be implemented using a spray tower filled with an alkaline absorbent or a dry chemical filter. This device is connected to the exhaust vent via a sealed pipeline, forming a closed treatment channel to prevent the escape of unpurified gas.

[0036] Specifically, the acidic gases generated during the electrolysis reaction naturally rise to the top of the electrolytic cell due to density differences. A through-hole in the center of the top plate guides the gas into the external piping via a centralized exhaust path, preventing disorderly diffusion within the cell. The piping system connecting to the acid mist purification device is made of corrosion-resistant materials, such as PVC or fiberglass, ensuring leak-free gas transport. After entering the purification device, the gas is neutralized and converted into salts through spraying with an alkaline solution or contact with a solid adsorbent, ultimately achieving compliant emissions.

[0037] Traditional electrolytic cells typically employ dispersed exhaust vents on the sidewalls, resulting in low gas collection efficiency and a tendency to create eddies that trap waste gas. Existing technologies often separate purification equipment from the electrolysis unit, leading to complex piping connections and insufficient sealing, which can easily cause secondary pollution. This solution utilizes a central through-hole in the top plate and directional piping to form a highly efficient gas collection path, combined with an integrated purification device to achieve fully enclosed waste gas treatment, significantly improving treatment efficiency and safety. This application can directionally collect acidic gases volatilized during electrolysis and achieve efficient neutralization through an external purification device, effectively preventing equipment corrosion and environmental pollution caused by direct emission of acid mist waste gas, while simplifying the structural layout of the waste gas treatment system.

[0038] This application also proposes that connecting blocks are fixedly installed at the four corners of side A of the electrolytic cell 1, and the sealing cover plate 12 is fixed to the connecting blocks by fastening bolts 14.

[0039] The connecting block refers to the support component fixed to the four corners of the side of electrolytic cell A. It can be made in one piece or fixed with bolts. Its function is to provide fixing points for the fastening bolts and ensure uniform force distribution during the installation of the sealing cover. The fastening bolts are threaded fasteners used for mechanical connection. They can be made of stainless steel. They press the sealing cover against the side of electrolytic cell A with preload, while allowing disassembly and maintenance.

[0040] Specifically, four connecting blocks are installed at the four corners of side A of the electrolytic cell using either integral molding or bolt fixing. After the sealing cover plate covers the opening of the electrolytic cell, fastening bolts are passed through the mounting holes on the edge of the cover plate and screwed into the threaded holes of the connecting blocks. The symmetrical layout of the four corner connecting blocks ensures that the sealing cover plate is subjected to even force during tightening, avoiding deformation or sealing failure due to localized stress concentration. The tightening of the fastening bolts compresses the sealing gasket between the sealing cover plate and the electrolytic cell through mechanical preload, forming a continuous sealing interface. When maintenance or replacement of the internal electrodes is required, the sealing cover plate can be removed simply by loosening the four corner fastening bolts, without destructive disassembly.

[0041] Traditional electrolytic cell sealing covers typically employ welded or integral fixed structures, necessitating cutting or forceful disassembly for maintenance, resulting in complex operations and difficulty in achieving repeated sealing. Existing removable cover technologies often rely on single-sided hinges or central fixing methods, which are prone to leakage due to uneven stress leading to seal interface misalignment. This solution, through the coordinated design of four corner connecting blocks and fastening bolts, achieves both rapid cover assembly and disassembly while maintaining seal stability through multi-point symmetrical pressure. This application solves the problems of complex installation structures and insufficient sealing performance of electrolytic cell sealing covers. The symmetrical mechanical connection at the four corners simplifies the cover fixing structure, while the bolt preload evenly compresses the sealing interface, effectively preventing electrolyte leakage and significantly improving the efficiency of cover assembly, disassembly, and maintenance.

[0042] This application further proposes that a sealing gasket 13 is provided at the connection between the sealing cover plate 12 and the A side of the electrolytic cell 1.

[0043] A gasket is a flexible sealing element placed between two rigid contact surfaces. It can be molded from corrosion-resistant rubber or silicone materials and fills the gaps between metal parts during assembly through compression deformation. Side A refers to the front opening end face of the electrolytic cell, which can be machined to form a planar sealing interface. Its surface roughness is controlled below Ra3.2 to ensure uniform pressure on the gasket.

[0044] Specifically, when the sealing cover is bolted to the side of electrolytic cell A, the sealing gasket is compressed and undergoes elastic deformation, completely filling the assembly gap between the cover and the cell. During the electrolytic reaction, this sealing structure forms a continuous physical isolation layer, preventing the chloric acid mist generated inside from escaping along the contact surface, while also preventing particulate matter in the outside air from entering the electrolytic cell through the gaps and interfering with the electrode reaction. The gasket, made of flexible material, can compensate for dimensional changes in rigid components due to thermal expansion under high-temperature conditions, avoiding problems such as cracking of the sealing surface or stress concentration caused by rigid contact.

[0045] Traditional electrolytic cell flange connections rely solely on direct contact sealing with a rigid surface, which is prone to micron-level gaps and leakage under long-term vibration and temperature variations. This solution, however, uses independent sealing gaskets to achieve a more uniform distribution of interfacial sealing pressure. Simultaneously, it utilizes the elastic properties of the material to maintain a dynamic sealing effect, overcoming the technical shortcomings of traditional rigid surface contact seals, such as poor adaptability to interfacial deformation. This application effectively prevents the leakage of corrosive gases during electrolytic cell operation, avoiding damage to the equipment's external walls and the surrounding environment from acid mist. It also maintains the purity of the internal environment of the electrolytic reaction system, ensuring the stability and continuity of the organic matter degradation reaction.

[0046] This application further proposes that the spacing between adjacent electrode slots is 3~5cm. The electrode slots can limit the electrode spacing between the anode and cathode plates, so that the electrolysis of the anode and cathode plates is within a reasonable electrolysis range.

[0047] This application further proposes that the titanium-based anode plate 2 includes a titanium-based support frame and two layers of titanium-based rhombic mesh fixedly disposed within the titanium-based support frame, thereby increasing the plate area of ​​the titanium-based anode plate and improving the surface strength of the titanium-based anode plate.

[0048] This application further proposes that the stainless steel cathode plate 3 has several through holes evenly distributed on it, which can improve the flowability of waste liquid.

[0049] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention.
