Description

Technical Field

[0001] This utility model relates to the field of carbon removal and solid waste treatment technology, specifically to a device for direct carbon capture and co-processing of solid waste. Background Technology

[0002] Most current carbon sequestration technologies are non-permanent and limited by processes. Existing carbon control processes mainly rely on secondary energy sources. Each kilowatt-hour of coal-fired power production generates 800 grams of carbon dioxide, but it's difficult to capture 800 grams of carbon dioxide from the use of that same amount of power. Traditional carbon capture technologies suffer from excessive energy consumption and numerous steps, resulting in capture yields less than indirect emissions. Even when using green energy for carbon capture, losses due to inversion, energy storage, and transmission mean the captured amount is less than the emission reduction benefits of direct use. Therefore, based on existing traditional carbon capture technologies, we have successfully developed a solar-powered energy management system. This system utilizes solar power generation, a PLC, and voltage transmitters to form the management system. It determines the load input based on the current voltage transmitter signal, achieving three safety features: automatic system startup, automatic automatic operation, and automatic automatic shutdown. Furthermore, our solar-powered energy management system has a direct application rate of over 90% in the photovoltaic energy technology field, exceeding that of competitors by more than three times.

[0003] When the boiler stops working, our equipment can continue to operate. At this time, the induced draft fan draws carbon dioxide from the air through the company's chimney and into the reaction tank. The equipment then becomes a direct atmospheric carbon dioxide capture device, serving multiple purposes.

[0004] In addition, the treatment of industrial waste such as calcium carbide slag slurry also faces enormous challenges. Direct discharge or simple landfill not only wastes resources but also causes serious environmental pollution.

[0005] Traditional governance methods often consume large amounts of energy and have low energy efficiency, which does not meet the requirements of sustainable development. Utility Model Content

[0006] To address the shortcomings of existing carbon removal technologies and the inefficiency of direct application of photovoltaic energy, this invention provides a photovoltaic carbon capture and solid waste co-processing device. This solves the problems of difficult and high-consumption treatment of carbon dioxide and industrial waste calcium carbide slag slurry. Furthermore, the device's power supply stage utilizes advanced energy-saving and environmentally friendly technologies beyond the traditional carbon removal power supply process (mains power, energy storage). This technology combines photovoltaic panel power generation with a PLC automation system and an energy management system, enabling direct on-site development and utilization of photovoltaic power without energy storage or inversion, and direct application of DC power to eliminate losses caused by inversion. This achieves a synergistic technological innovation that combines maximum photovoltaic efficiency with carbon capture.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a photovoltaic carbon capture and solid waste co-processing device, comprising a reaction tank and a chimney, wherein the reaction tank is provided with an inlet and an outlet, a main flue pipe is connected to the side wall of the chimney, an induced draft fan is connected to one side of the main flue pipe, an inlet duct is connected between the induced draft fan and the inlet, a spray reaction mechanism is provided inside the reaction tank, an outlet duct is connected to the outlet, a discharge pipe is connected between the reaction tanks, and a solenoid valve is provided at the bottom of the tank.

[0008] Furthermore, the spray reaction mechanism includes a partition plate fixedly installed inside the reaction tank. The partition plate has an opening in the middle and a gap between its lower end and the lower wall of the reaction tank. A pressure plate is provided on the wall of the partition plate at an angle of 45° to the smoke inlet direction of the opening. A spray pipe is provided on the upper wall of the pressure plate. The spray pipe is connected to a feeding circulation pipe. One end of the feeding circulation pipe is connected to a feeding circulation pump. The liquid inlet end of the feeding circulation pump is located inside the tank. The spray pipe has a nozzle.

[0009] Furthermore, the housing is equipped with an online pH meter and a liquid level meter. A second housing is provided on one side of the housing, and a conduit is provided inside the second housing. One end of the conduit is connected to a pump body, and the inlet end of the pump body is located inside the housing. Beneficial effects

[0010] This utility model provides a device for direct carbon capture and co-processing of solid waste, which has the following beneficial effects:

[0011] From an energy perspective, direct photovoltaic utilization generates the highest returns. The highest power generation efficiency during energy storage and release is unlikely to exceed 20%, while inverter consumption is around 50%. Utilizing photovoltaic technology can significantly reduce infrastructure costs, simplify processes, and improve energy utilization efficiency.

[0012] Using industrial solid waste calcium carbide slag slurry as raw material, the main component of which is calcium hydroxide, it reacts with carbon dioxide to produce calcium carbonate and water, achieving simultaneous treatment and reducing environmental pollution. This not only solves the waste disposal problem but also achieves simultaneous treatment of industrial solid waste and flue gas. While generating no new emissions or additional electricity consumption, it maximizes the utilization of photovoltaic energy and ultimately achieves the goal of permanently removing carbon dioxide from the carbon cycle by converting it into carbonate. The generated calcium carbonate product can also be used in papermaking, PVC production, coatings, building materials, and other fields. The water produced also has a recycling function, showing broad application prospects. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-2 This utility model provides a technical solution: a photoelectric carbon capture and solid waste co-processing device, including a reaction tank box 5, a chimney 1, and a box 24. The reaction tank box 5 is provided with a flue gas inlet 21 and a flue gas outlet 22. A flue gas main pipe 2 is connected to the side wall of the chimney 1. An induced draft fan 4 is connected to one side of the flue gas main pipe 2. An inlet duct 3 is connected between the induced draft fan 4 and the inlet 21. A spray reaction mechanism is provided inside the reaction tank box 5. A flue gas outlet duct 11 is connected to the outlet 22. A discharge pipe 16 is connected between the reaction tank box 5 and the box 24. A solenoid valve 14 is provided at the bottom of the box 24.

[0018] The calcium carbide slag slurry inside the calcium carbide slag slurry feeding tank 2 is an industrial waste material, which is the waste residue with calcium hydroxide as the main component after the hydrolysis of calcium carbide to obtain acetylene gas. At present, the treatment of calcium carbide slag mainly adopts direct discharge or simple landfill, which not only wastes resources but also causes serious environmental pollution. This technology transforms industrial waste such as calcium carbide slag slurry into harmless substances and produces valuable calcium carbonate products, realizing the recycling of resources and improving economic benefits.

[0019] In the field of energy technology, this design flexibly uses three power supply systems. The system achieves efficient and stable power supply to the equipment through three methods: direct application of photovoltaics, use of photovoltaic energy storage, and grid power supply.

[0020] Direct photovoltaic application: This technology refers to the direct conversion of solar energy into electrical energy and its utilization. Industrial computers efficiently utilize the direct current generated by photovoltaic panels, and an automated energy management system uses current voltage transmitter signals to determine load distribution. This method has advantages such as being clean, renewable, and pollution-free.

[0021] Photovoltaic energy storage applications: The electricity generated by photovoltaic power generation is often limited by factors such as weather and time. In order to achieve a continuous and stable supply of electricity, photovoltaic energy storage technology is adopted. By storing the excess electricity generated by photovoltaic power generation for unforeseen needs, the efficiency and stability of energy utilization are improved.

[0022] Mains power supply: The system automatically switches to mains power supply mode at night or when the equipment's energy storage is insufficient or the voltage is unstable, ensuring normal equipment operation. This allows the equipment to receive a stable power supply under any circumstances, improving its reliability and usability.

[0023] The three-electricity power supply system used is used to supply the electricity required for this process. Due to the instability of photovoltaic power generation, direct power supply to computers can cause damage to computer hardware. Currently, only we can achieve this in this field. The traditional photovoltaic-storage-inverter process can only achieve an energy utilization rate of 16% to 22%. If it is a photovoltaic-direct power supply system, the power generation utilization rate will not exceed 40%, while direct development and utilization of photovoltaics can achieve a photovoltaic utilization efficiency of over 90%.

[0024] In this design, the reaction tank 16 can also be composed of several reaction tanks 16 connected in series to form a large reaction tank, thereby increasing the treatment effect. Alternatively, several reaction tanks 16 can be connected in parallel to increase the inflow of flue gas.

[0025] Furthermore, the spray reaction mechanism includes a partition 9 fixedly installed inside the reaction tank 5. The partition 9 has an opening 8 in the middle and a gap 19 between its lower end and the lower wall of the reaction tank 5. A pressure plate 7 is provided on the wall of the partition 9 at an angle of 45° to the smoke inlet direction of the opening 8. A spray pipe 6 is provided on the upper wall of the pressure plate 7. The spray pipe 6 is connected to a feeding circulation pipe 10. One end of the feeding circulation pipe 10 is connected to a feeding circulation pump 15. The liquid inlet end of the feeding circulation pump 15 is located inside the tank 24. The spray pipe 6 has a nozzle 20.

[0026] Furthermore, the housing 24 is equipped with an online pH meter 12 and a liquid level meter 13. A second housing 23 is provided on one side of the housing 24. A conduit 18 is provided inside the second housing 23. One end of the conduit 18 is connected to a pump body 17. The inlet end of the pump body 17 is located inside the housing 24.

[0027] Furthermore, the process of waste disposal includes:

[0028] S1: First, the induced draft fan 4 is automatically started, and the carbon dioxide gas in the chimney 1 is blown into the reaction tank box 5 through the flue gas inlet duct 3. Since the flue gas inlet 8 in the reaction tank box 5 is equipped with a pressure plate 7, a positive pressure will be formed on the pressure plate 7. Then, the feeding pump circulation pump 15 is started, and the carbide slag slurry in the box 24 is sprayed out from the nozzle 20 on the injection pipe 6 through the feeding circulation pipe 10 onto the pressure plate 7.

[0029] S2: Since the pressure plate 7 is installed to block the smoke inlet direction, a wind pressure surface will be formed, which increases the pressure of carbon dioxide gas on the pressure plate 7, increases the speed of carbon dioxide forming carbonic acid, and makes the carbonic acid falling from the spray react as much as possible to produce calcium carbonate precipitate at the bottom of the reaction tank 5. Since there are several spray pipes 6 and baffles 9, carbon dioxide in the gas can be effectively removed.

[0030] S3: Finally, the current pH data is continuously transmitted back to the PLC management system via the online pH meter 12. When the pH value reaches approximately 8, after a certain delay, pump 17 is started first to add water from the second tank 24 to tank 23 through conduit 18, thus saving water. When the level gauge reaches the set value, pump 17 stops working, and the program automatically starts solenoid valve 14 to discharge calcium carbonate and a small amount of impurities from tank 24. Then, new calcium carbide slag slurry is added to continue operation.

[0031] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0032] Example: In use, the induced draft fan 4 is automatically started first, blowing carbon dioxide gas from the chimney 1 into the reaction tank 5 through the flue gas inlet duct 3. Since the inlet 8 of the reaction tank 5 is equipped with a pressure plate 7 in the direction of flue gas inlet, a positive pressure is formed on the pressure plate 7. Then, the feed pump circulation pump 15 is started, spraying the carbide slag slurry in the tank 24 through the feed circulation pipe 10 from the nozzle 20 on the spray pipe 6 onto the pressure plate 7. Then, since the inlet direction of flue gas is blocked by pressure plates 7, a wind pressure surface is formed, thus increasing the pressure of carbon dioxide gas on the pressure plate 7. The pressure on the surface increases the rate at which carbon dioxide forms carbonic acid, allowing the sprayed carbonic acid to react as much as possible to produce calcium carbonate, which precipitates at the bottom of the reaction tank 5. Because there are several spray pipes 6 and baffles 9, carbon dioxide in the gas can be effectively removed. Finally, the current pH data is continuously transmitted back to the PLC management system via the online pH meter 12. When the pH value reaches approximately 8, after a certain delay, pump 17 is started first, and water from the second tank 24 is added to tank 23 through conduit 18, achieving water conservation. When the level gauge reaches the set value, pump 17 stops working, and the program automatically starts solenoid valve 14 to discharge calcium carbonate and a small amount of impurities from tank 24. Then, new calcium carbide slag slurry is added to continue operation.
