Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an electrochemical treatment device for dyeing and printing wastewater. Background Technology

[0002] Electrocoagulation is a method of removing pollutants using physicochemical coagulation reactions in the field of water treatment. The reaction principle of electrocoagulation involves using metals such as aluminum or iron as the anode. Under the action of direct current, the anode is dissolved, producing Al and Fe ions. Through a series of hydrolysis, polymerization, and ferrous oxidation processes, these ions develop into various hydroxyl complexes, polynuclear hydroxyl complexes, and even hydroxides, causing colloidal and suspended impurities in dyeing and printing wastewater to coagulate and precipitate, thus separating them. Simultaneously, charged pollutant particles migrate in the electric field, and some of their charge is neutralized by the electrodes, promoting their destabilization and aggregation.

[0003] In the existing technology, the electrocoagulation device mainly consists of an electrolytic reaction cell, a high-voltage pulse power supply and a control system. It mainly uses industrial electricity to provide the energy required for electrolysis by converting it into DC power through the high-voltage pulse power supply. This requires a lot of electrical energy and electrode plates, resulting in high operating costs. At the same time, the pulse power supply has a large initial investment, low cost-effectiveness, and cannot be repaired in a timely manner if the electrode plates are damaged. Utility Model Content

[0018] 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.

[0019] Please see Figures 1-4 This utility model discloses an electrochemical treatment device for dyeing and printing wastewater, including a box 1. The upper surface of the box 1 is open. An inlet pipe 2 is provided on the upper side of the right side wall of the box 1, and an outlet pipe 3 is provided on the upper side of the left side wall of the box 1. An aeration mechanism 4 is provided inside the box 1 near the lower side.

[0020] Specifically, the aeration mechanism 4 includes a partition 401, an air distribution chamber 402, an aeration head 403, and an air pipe 404. The partition 401 is fixedly installed on the inner wall of the box 1 near the lower side. An air distribution chamber 402 is formed between the lower surface of the partition 401 and the lower inner wall of the box 1. Aeration heads 403 are evenly arranged on the upper surface of the partition 401. An air pipe 404 is installed on the partition 401 near the left side, and the air pipe 404 extends out of the outer side of the left side wall of the box 1.

[0021] In this embodiment, the air pipe 404 is connected to the air pump, so that the gas flows into the air distribution chamber 402 on the lower side of the partition 401, and is blown into the box 1 through the aeration head 403, causing the water to tumble and making the electrocoagulation effect better.

[0022] Specifically, the positive electrode conductive mechanism 5 includes a fixed conductive rod 501 and a positive electrode plate 502. The fixed conductive rod 501 is installed in the middle of the upper surface of the housing 1, and the positive electrode plate 502 is evenly arranged on the lower surface of the fixed conductive rod 501 from left to right.

[0023] In this embodiment, the fixed conductive rod 501 is connected to the positive terminal of the control mechanism 8 to provide positive electrical energy to the positive electrode plate 502. Waste iron plates and other iron profiles can be used as the anode electrode plate.

[0024] Specifically, the negative electrode conductive mechanism 6 includes a guide sleeve 601, a movable conductive rod 602, a negative electrode plate 603, and an electric linear module 604. Two guide sleeves 601 are arranged on the left and right sides. The guide sleeves 601 are fixedly installed on the left and right sides of the housing 1 near the upper side, and the movable conductive rod 602 is movably inserted into the left and right guide sleeves 601. The lower surface of the movable conductive rod 602 is evenly arranged with negative electrode plates 603 from left to right. The electric linear module 604 is fixedly installed on the left side of the housing 1, and the upper surface of the slide of the electric linear module 604 is fixedly connected to the right end of the movable conductive rod 602.

[0025] In this embodiment, the electric linear module 604 slide table drives the movable conductive rod 602 to move left and right within the guide sleeve 601, so that the movable conductive rod 602 drives the negative electrode plate 603 to move left and right, thereby achieving the effect of adjusting the distance between the negative electrode plate 603 and the positive electrode plate 502.

[0026] Specifically, the positive electrode plate 502 and the negative electrode plate 603 are arranged at intervals on the left and right.

[0027] In this embodiment, the positive electrode plate 502 and the negative electrode plate 603 can perform electrocoagulation better.

[0028] Specifically, the control mechanism 8 includes a controller 801, an information processing module 802, a relay 803, a current sensor 804, a voltage sensor 805, a wireless communication module 806, a display screen 807, and control buttons 808. The controller 801, information processing module 802, relay 803, current sensor 804, voltage sensor 805, and wireless communication module 806 are installed inside the control box 7. The display screen 807 and control buttons 808 are installed on the front side of the control box 7. The controller 801 is connected to the information processing module 802, relay 803, current sensor 804, voltage sensor 805, wireless communication module 806, display screen 807, and control buttons 808. The relay 803 is electrically connected to the fixed conductive rod 501, the movable conductive rod 602, and the solar panel 9. The current sensor 804 and voltage sensor 805 are installed on the wires input to the solar panel 9. The controller 801 is electrically connected to the backend server 10 through the wireless communication module 806.

[0029] In this implementation, relay 803 electrically connects solar panel 9 to positive electrode plate 502 and negative electrode plate 603. Current and voltage generated by solar panel 9 are collected by current sensor 804 and voltage sensor 805. Information processing module 802 processes the current and voltage information, calculates the current density, and feeds the information back to controller 801. Controller 801 adjusts the distance between positive electrode plate 502 and negative electrode plate 603. Controller 801 also feeds back the voltage, current, current density, and electrode distance of the equipment processed by information processing module 802 to the backend server 10 via wireless communication module 806. This allows operators to view the equipment's operating status through a browser or mini-program. The mini-program provides real-time reminders when electrode replacement is needed or when a fault occurs. The system selects the electrode material parameters and automatically matches the optimal process parameters, enabling various types of waste iron profiles that were previously difficult to utilize to be used as anode electrodes.

[0030] In use, the solar panel 9 is installed in the empty space above the biochemical tank of the dyeing and printing wastewater treatment plant. The positive and negative electrodes of the solar panel 9 are electrically connected to the positive electrode plate 502 and the negative electrode plate 603 through the relay 803 in the control mechanism 8. The current and voltage generated by the solar panel 9 are collected by the current sensor 804 and the voltage sensor 805. The current and voltage information is processed by the information processing module 802, and the current density is calculated. The information is fed back to the controller 801, which causes the slide of the electric linear module 604 in the negative electrode conductive mechanism 6 to move. The movable conductive rod 602 moves left and right within the guide sleeve 601, causing the negative electrode plate 603 to move left and right, thus adjusting the distance between the negative electrode plate 603 and the positive electrode plate 502. The low-voltage DC power generated by the 12V photovoltaic panel is used as the electrocoagulation power source, eliminating the need for the inverter and high-voltage DC power source originally required by the photovoltaic system. The system monitors voltage and current; when the light intensity changes, the voltage and power of the solar panel 9 change accordingly. The controller 801 receives the voltage and current signals, and the information processing module 802 calculates the optimal voltage and current. The optimal electrode spacing is achieved by adjusting the distance between the positive electrode plate 502 and the negative electrode plate 603, ensuring that the voltage and power generated under the current light intensity are utilized most efficiently for the electrocoagulation reaction. Furthermore, the controller 801 transmits the voltage, current, current density, and electrode spacing processed by the information processing module 802 to the backend server 10 via the wireless communication module 806. This allows operators to monitor the equipment's operating status via a browser or app, and receives real-time alerts on the app when electrode replacement is needed or a malfunction occurs. Using a photovoltaic system as the power source provides… This invention effectively utilizes the spare space above the biochemical tank of a dyeing and printing wastewater treatment plant, using photovoltaics as a green power source to improve the greening level of the wastewater treatment plant. The DC power generated by the photovoltaic system itself originally needed to be converted into AC power by an inverter, with an inverter efficiency of 90% (direct output) to 80% (energy storage output), and a comprehensive efficiency of about 70%. In addition, the high-voltage pulse power supply originally required for electrocoagulation has an efficiency of 95%. This invention cleverly couples photovoltaics and electrocoagulation, eliminating the need for inverters, energy storage, and high-voltage pulse power supplies, improving energy efficiency by more than 30%, thereby reducing operating costs and reducing one-time investment.

[0031] In summary, this electrochemical treatment device for dyeing and printing wastewater cleverly couples photovoltaics and electrocoagulation, eliminating the need for inverters, energy storage, and high-voltage pulse power supplies, thus improving energy efficiency by more than 30% and reducing operating costs. It uses photovoltaic power as the electrocoagulation power source, and the control mechanism 8 automatically adjusts the optimal electrode distance for different waste iron profiles under different light intensities and voltages. The Internet of Things improves the convenience of operation and maintenance.
