Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a low-carbon and energy-saving narrow-flow composite electrocatalytic oxidation intelligent complete set of equipment. Background Technology

[0002] Electrocatalytic oxidation is a catalytic oxidation technology based on electrochemical reactions, belonging to the category of advanced oxidation technologies. It introduces the liquid to be treated into an electrolytic cell, where, under the influence of an electric current, active groups such as hydroxyl radicals are generated on the surface of the electrode materials to oxidize organic matter in the water. This reduces chemical oxygen demand (COD), ammonia nitrogen, removes color, and improves biodegradability. The principle of electrocatalytic oxidation is based on electrochemical technology. It utilizes free radicals and strong oxidizing particles (such as hydroxyl radicals, ozone, and hydrogen peroxide) generated during the electrolytic catalytic reaction to rapidly and non-selectively chain-react with organic pollutants in wastewater, oxidizing and degrading them. This transforms recalcitrant high-molecular-weight organic matter into biodegradable small-molecule compounds, and even ultimately decomposes them into carbon dioxide and water.

[0003] Electrocatalytic oxidation technology, as a highly efficient wastewater treatment technology, has attracted much attention due to its advantages such as no need to add reagents and no secondary pollution. However, this technology consumes a lot of energy during the reaction process, which limits its development and application in areas with insufficient energy. Therefore, a low-carbon and energy-saving narrow-flow composite electrocatalytic oxidation intelligent complete set of equipment is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a low-carbon, energy-saving, narrow-flow composite electrocatalytic oxidation intelligent complete set of equipment to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A low-carbon, energy-saving, narrow-flow composite electrocatalytic oxidation intelligent complete set of equipment includes a box body, in which a sewage treatment component and a cooling component are respectively installed. Multiple brackets are fixedly installed on the top side of the box body, and the same solar panel is fixedly installed on the top side of the multiple brackets. An energy storage battery is fixedly installed on the top side of the box body. An external cable is provided on one side of the box body, and an automatic switch is provided on the outside of the external cable. A rectifier is provided at the bottom end of the external cable. The rectifier, the automatic switch, and the energy storage battery are all electrically connected to a current controller.

[0007] Preferably, the wastewater treatment component includes two electrolytic cells fixedly installed inside the tank body. Two connecting blocks are fixedly installed on the top inner wall and the bottom inner wall of the two electrolytic cells. The same reaction tank is fixedly connected to the side of each pair of connecting blocks that are close to each other.

[0008] Preferably, multiple insulating pads are fixedly installed on the inner walls of the two reaction tanks, each insulating pad contains an electrode, each electrode has a water-permeable hole, and each electrode has a circular hole above and below it.

[0009] Preferably, wastewater inlets and outlets are fixedly installed at both ends of the two electrolytic cells, and both wastewater inlets and outlets are connected to the reaction cell; the electrolytic cells are connected in series, and each electrolytic cell automatically adjusts the reaction current and voltage according to its influent concentration and target removal rate, effectively reducing power consumption loss.

[0010] Preferably, the cooling assembly includes a cooling tank and a water pump fixedly installed on the bottom inner wall of the tank body, an extraction pipe fixedly installed on one side of the water pump, and the other end of the extraction pipe fixedly connected to one side of the cooling tank and communicating with the cooling tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By incorporating solar panels, the DC power generated by solar energy can directly power the equipment, greatly simplifying the circuit design and improving overall efficiency. This allows for simultaneous solar charging and load power supply, effectively avoiding secondary energy losses caused by the charging and discharging conversion of the energy storage battery. Furthermore, the rectifier provides power to the electrocatalytic oxidation equipment, which, as a DC load, does not require DC-AC conversion, thus simplifying the circuit design and improving charging speed and efficiency.

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.

[0023] Reference Figure 1-5A low-carbon, energy-saving, narrow-current composite electrocatalytic oxidation intelligent complete set of equipment includes a box body 1, inside which a wastewater treatment component and a cooling component are respectively installed. Multiple supports 2 are fixedly installed on the top side of the box body 1, and a single solar panel 3 is fixedly installed on the top side of the supports 2. An energy storage battery 4 is fixedly installed on the top side of the box body 1. An external cable 6 is provided on one side of the box body 1, and an automatic switch 7 is provided on the outside of the external cable 6. A rectifier 8 is provided at the bottom end of the external cable 6. The rectifier 8, the automatic switch 7, and the energy storage battery 4 are all electrically connected to a current controller 5. By incorporating the solar panel 3, the DC power generated by solar power can directly power the equipment, greatly simplifying the circuit design and improving the overall efficiency. It achieves simultaneous solar charging and load power supply, effectively avoiding the problems caused by the energy storage battery. 4. Secondary energy loss caused by charging and discharging conversion. In addition, this device is equipped with municipal power supply as a backup power source. Through precise calculation and optimized design, this device successfully reduces the number of photovoltaic panels used and improves economic efficiency. By setting up a current controller 5, which can accurately control the charging and discharging process of the energy storage battery 4, when the voltage of the energy storage battery 4 is lower than the preset value, the system will automatically start the undervoltage protection mechanism, shut down the photovoltaic power supply, and automatically switch to the mains power supply mode. The rectifier 8 provides power to the electrocatalytic oxidation equipment. The electrocatalytic oxidation equipment is a DC load and does not need to be converted from DC to AC, thereby simplifying the circuit design and improving the charging speed and efficiency. This system not only realizes the synchronous operation of battery charging and load power supply, effectively extending the service life of the battery, but also significantly reduces energy loss.

[0024] Specifically, the wastewater treatment component includes two electrolytic cells 9 fixedly installed inside the main body 1. Two connecting blocks 10 are fixedly installed on the top and bottom inner walls of each electrolytic cell 9. Each set of connecting blocks 10 is fixedly connected to the same reaction tank 11 on its closest side. The reaction tank 11 has a tubular structure. When a unit volume of wastewater passes through, its cross-sectional area is smaller than that of conventional devices, resulting in a relatively increased flow velocity within the tank. This increased flow velocity not only helps the wastewater pass through the reaction tank faster but also enhances the relative motion between the wastewater and the electrodes, thereby improving the contact frequency and efficiency between the wastewater and the electrodes. Multiple insulating pads 12 are fixedly installed on the inner walls of the two reaction tanks 11. Each insulating pad 12 contains an electrode plate 13, and each electrode plate 13 has water-permeable holes. When wastewater passes through the electrode plates, the smaller holes and reduced cross-sectional area increase the flow velocity, creating a narrower fluid channel and resulting in a narrow flow. Narrow flow generates turbulence or eddies when passing through small holes, and this disturbance helps accelerate chemical reactions or physical processes in wastewater. When wastewater passes through different electrode holes, the fluid mixing and redistribution caused by the change in channel direction form cross-flow. Cross-flow can make the wastewater more uniformly distributed inside the electrode, avoiding excessively high or low local concentrations. Circular holes are opened above and below multiple electrode plates 13. The circular holes opened above the multiple electrode plates 13 are equipped with the same anode wire 14, and the circular holes opened below the multiple electrode plates 13 are equipped with cathode wires 15. Wastewater inlets 16 and wastewater outlets 17 are fixedly installed at both ends of the two electrolytic cells 9, respectively. Both wastewater inlets 16 and wastewater outlets 17 are connected to the reaction tank 11. Multiple electrode plates 13 are fixed inside the reaction tank 11, and the outer side of the electrode plates 13 is protected by insulating pads 12. 2. The electrode is fixedly connected to the inner wall of the reaction tank 11. The insulating pad 12 can protect the electrode 13 and prevent it from being deformed or damaged. The circular hole at the top of the electrode 13 is connected to the anode wire 14. An insulating layer is provided between the circular hole at the bottom and the cathode wire 15 to achieve the effect of insulation. The circular hole at the bottom of the electrode 13 is connected to the cathode wire 15. An insulating layer is provided between the circular hole at the top and the anode wire 14 to achieve the effect of insulation. Water passage holes are evenly distributed on the electrode 13. Untreated wastewater enters through the wastewater inlet 16 and passes through the water passage holes between the electrodes 13. After the reaction, the effluent is discharged from the wastewater outlet 17 at the other end of the electrolytic cell 9 to enter the next process.

[0025] Specifically, the cooling assembly includes a cooling tank 18 and a water pump 19 fixedly installed on the bottom inner wall of the tank body 1. An extraction pipe 20 is fixedly installed on one side of the water pump 19, and the other end of the extraction pipe 20 is fixedly connected to and communicates with one side of the cooling tank 18. The same branch pipe 22 is fixedly installed on the bottom of the two electrolytic cells 9. A delivery pipe 21 is fixedly installed on the other side of the water pump 19, and the other end of the delivery pipe 21 is fixedly connected to and communicates with one side of the branch pipe 22. The same connecting pipe 23 is fixedly installed on the bottom of the two electrolytic cells 9, and the other end of the connecting pipe 23 is fixedly connected to and communicates with one side of the cooling tank 18. The system is equipped with a water pump 19 and a cooling tank 18. When the temperature of the reaction tank 11 is too high, the water pump 19 drives the extraction pipe 20 to extract the coolant from the cooling tank 18. The coolant is then transported to the distribution pipe 22 through the delivery pipe 21. The distribution pipe 22 is connected to the two electrolytic cells 9, so the coolant will enter the two electrolytic cells 9 through the distribution pipe 22, thereby cooling the reaction tank 11, ensuring the stable operation of the equipment and protecting it from damage. After circulating outside the reaction tank 11, the coolant will be discharged back into the cooling tank 18 through the connection pipe 23, thereby realizing the recycling of the coolant.

[0026] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer for control.

[0027] In use: By incorporating solar panels 3, the DC power generated by solar power can directly supply the equipment, greatly simplifying circuit design and improving overall efficiency. This achieves simultaneous solar charging and load power supply, effectively avoiding secondary energy losses caused by the charging and discharging conversion of the energy storage battery 4. Furthermore, to ensure stable system operation under adverse environmental conditions (such as the rainy season or at night), the device is also equipped with municipal power as a backup power source. Through precise calculation and optimized design, the device successfully reduces the number of photovoltaic panels used, improving economic efficiency. The current controller 5 precisely controls the charging and discharging process of the energy storage battery 4. When the voltage of the energy storage battery 4 falls below a preset value, the system automatically activates the undervoltage protection mechanism, shuts off the photovoltaic power supply, and automatically switches to mains power mode. The rectifier 8 provides power to the electrocatalytic oxidation equipment. As a DC load, the electrocatalytic oxidation equipment does not require DC-AC conversion, thus simplifying circuit design and improving efficiency. To improve charging speed and efficiency, this system not only enables simultaneous charging of the battery and power supply to the load, effectively extending the battery's lifespan, but also significantly reduces energy loss. During the morning to afternoon when power generation is high, solar panel 3 directly supplies power to the electrocatalytic oxidation equipment, with any remaining power stored in energy storage battery 4. As power generation gradually decreases in the afternoon, both solar panel 3 and energy storage battery 4 supply power to the electrocatalytic oxidation equipment. When solar panel 3 is not generating power, energy is directly supplied by energy storage battery 4. During the night, when electricity prices are at their lowest and during off-peak hours, the energy in energy storage battery 4 is almost depleted, and the mains power supply system is activated. The mains power is connected to energy storage battery 4 through rectifier 8. During periods of lower electricity prices, part of the mains power supplies the electrocatalytic oxidation equipment, while the other part stores power in energy storage battery 4. When electricity prices enter peak hours and solar panel 3's power generation is still insufficient, energy storage battery 4 works in conjunction with solar panel 3 to power the electrocatalytic oxidation equipment.
