Technical Field
[0001] This utility model relates to the field of carbon capture and recovery technology, specifically a carbon capture and recovery device based on waste heat directional recovery. Background Technology
[0002] Carbon capture, utilization, and storage (CCUS) is a cutting-edge technology aimed at reducing atmospheric carbon dioxide concentration. This technology uses physical adsorption, chemical absorption, or membrane separation to capture carbon dioxide from industrial emission sources (such as coal-fired power plants and steel mills) or directly from the atmosphere. The carbon dioxide is then compressed, transported, and converted into high-value-added products through chemical transformation and biosynthesis, such as biodegradable plastics, building materials, or for enhanced oil recovery (EOR). Unusable portions are permanently stored in deep underground geological structures, achieving resource utilization and negative emissions of carbon dioxide. With technological breakthroughs and policy incentives, CCUS is expected to become a crucial support for energy transition under the goal of carbon neutrality.
[0003] For example, patent CN219072548U discloses a carbon capture carbon dioxide separation and recovery device, including a base, a separation and recovery mechanism on the base, and auxiliary components on the base. The separation and recovery mechanism includes a box fixedly installed on the top of the base, an installation box fixedly installed on the top of the box, and a motor fixedly installed inside the installation box. However, in the use of existing devices, due to the high humidity inside the device shell, carbon and other impurities easily adhere to the inner wall surface of the shell, forming stubborn deposits. These deposits are not only difficult to clean, consuming a lot of manpower and time, but also, as the deposits accumulate, they hinder the internal gas flow and material reactions, greatly reducing the working efficiency of the device. Furthermore, the existing devices have poor heat insulation performance. During heat transfer and storage, a large amount of heat is lost to the external environment through the shell. This not only leads to energy waste but also results in low waste heat recovery efficiency, failing to fully utilize the role of waste heat in the carbon capture and recovery process, thus affecting the energy consumption performance and operating economy of the entire device.
[0004] Therefore, in order to solve such problems, we propose a carbon capture and recovery device based on waste heat directional recovery. Utility Model Content
[0005] The purpose of this invention is to provide a carbon capture and recovery device based on waste heat directional recovery, in order to solve the problems mentioned in the background art. In existing devices, due to the high humidity inside the casing, carbon and other impurities easily adhere to the inner wall surface of the casing, forming stubborn deposits. These deposits are not only difficult to clean, requiring significant manpower and time, but also, as they accumulate, hinder internal gas flow and material reactions, greatly reducing the device's efficiency. Furthermore, existing devices have poor insulation performance; during heat transfer and storage, a large amount of heat is lost to the external environment through the casing. This not only leads to energy waste but also results in low waste heat recovery efficiency, failing to fully utilize waste heat in the carbon capture and recovery process, thus affecting the overall energy consumption and operational economy of the device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon capture and recovery device based on waste heat directional recovery, comprising a tank and a base fixedly connected to the bottom of the tank. A cover plate is provided on the top of the tank. A first motor is fixedly connected to the middle of the top surface of the cover plate.

[0010] Furthermore, an annular groove is provided on the tank body, and an insulation body is engaged and connected inside the annular groove.
[0011] Furthermore, the middle part of the cover plate and the bottom of the tank are both fixedly connected with oil seals, and the oil seals are rotatably connected to the first rotating rod and the second rotating rod.
[0012] Furthermore, an exhaust pipe is connected through the right side of the top of the cover plate, and a first solenoid valve is installed on the exhaust pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are: a carbon capture and recovery device based on waste heat directional recovery adopts a novel structural design, the specific details of which are as follows:
[0014] (1) The carbon capture and recovery device based on waste heat directional recovery, through the synergistic action of components such as telescopic stirring rod, scraper, side block and spring, mixes and stirs carbon dioxide flue gas and absorbent to promote a more complete reaction. At the same time, the scraper can clean the inner wall of the tank. Specifically, during the rotation of the telescopic stirring rod, the scraper at its outer end can stick to the inner wall of the tank. When encountering stubborn deposits, the spring at the outer end of the side block will be compressed or extended due to the force, so that the scraper always keeps in contact with the inner wall, thereby effectively removing carbon and other impurities that are stuck to the wall due to the high humidity inside the device shell. This avoids the problem of deposits accumulating and hindering the internal gas flow and material reaction, greatly reducing the working efficiency of the device, and also reducing the manpower and time costs of later cleaning.
[0015] (2) The carbon capture and recovery device based on waste heat directional recovery utilizes the synergistic effect of components such as annular groove and insulation body. The annular groove is used to install the insulation body, which can keep the temperature inside the tank. This effectively solves the problem of poor insulation performance of existing devices, prevents a large amount of heat from being lost to the external environment through the shell during heat transfer and storage, avoids energy waste, improves waste heat recovery efficiency, gives full play to the role of waste heat in the carbon capture and recovery process, and thus improves the energy consumption performance and operating economy of the entire device.
[0016] Furthermore, both the outer wall of the cover plate and the upper part of the outer wall of the tank are fixedly connected with lugs, and fixing bolts are threaded onto the lugs. Through the cooperation of the fixing bolts and lugs, a stable connection between the cover plate and the tank body can be achieved. At the same time, when it is necessary to inspect or maintain the inside of the device, the fixing bolts can be easily removed and the cover plate can be taken off, which provides convenience for operation. The middle part of the cover plate and the bottom of the tank body are fixedly connected with oil seals, and the oil seals are rotatably connected to the first rotating rod and the second rotating rod. The oil seals can effectively prevent gas or liquid leakage inside the tank body, while ensuring the sealing and stability of the first rotating rod and the second rotating rod during rotation, ensuring the normal operation of the device.

[0025] 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.
[0026] This utility model provides the following technical solution: a carbon capture and recovery device based on waste heat directional recovery.
[0027] Example 1: A carbon capture and recovery device based on waste heat directional recovery utilizes the synergistic action of components such as a telescopic stirring rod 23, a scraper 231, a side block 24, and a spring 241. The telescopic stirring rod 23 mixes and stirs the carbon dioxide flue gas with the absorbent, resulting in a more complete reaction. The scraper 231 cleans the inner wall of the tank 1, facilitating later use and preventing carbon and other impurities from easily adhering to the inner wall surface of the shell due to high humidity, forming stubborn deposits. These deposits are not only difficult to clean, consuming a lot of manpower and time, but also, with the accumulation of deposits, they hinder the internal gas flow and material reaction, greatly reducing the working efficiency of the device. Figure 1 - Figure 5As shown, a carbon capture and recovery device based on waste heat directional recovery includes a tank 1 and a base 3 fixedly connected to the bottom of the tank 1. A cover plate 11 is provided on the top of the tank 1. A first motor is fixedly connected to the middle of the top surface of the cover plate 11. A first rotating rod 2 is fixedly connected to the output end of the first motor. A limiting rod 21 is fixedly connected to the bottom of the first rotating rod 2. A second rotating rod 22 is sleeved on the outer wall of the limiting rod 21, and the bottom of the second rotating rod 22 penetrates the bottom of the tank 1. The bottom of the second rotating rod 22 is fixedly connected to... A second motor is connected to the first rotating rod 2 and the second rotating rod 22. Telescopic stirring rods 23 are evenly fixedly connected to the outer walls of the first rotating rod 2 and the second rotating rod 22. A scraper 231 is fixedly connected to the outer end of the telescopic stirring rod 23. Side blocks 24 are fixedly connected to the left side of the top and bottom of the telescopic stirring rod 23. A spring 241 is fixedly connected to the outer end of the side block 24. The outer end of the spring 241 is fixedly connected to the inner wall of the scraper 231. A hanging ear 12 is fixedly connected to the upper part of the outer wall of the cover plate 11 and the outer wall of the tank 1. A fixing bolt 121 is threadedly connected to the hanging ear 12.
[0028] The device mainly consists of a tank 1, a base 3, a cover plate 11, a first motor, a first rotating rod 2, a limiting rod 21, a second rotating rod 22, a second motor, a telescopic stirring rod 23, and a scraper 231. The first motor is fixedly installed in the middle of the top surface of the cover plate 11, and its output end is fixedly connected to the first rotating rod 2. The bottom of the first rotating rod 2 is fixedly connected to the limiting rod 21, which is sleeved on the outer wall of the second rotating rod 22. The bottom of the second rotating rod 22 penetrates the bottom of the tank 1 and is fixedly connected to the second motor fixed to the bottom of the tank 1. When the first motor starts, it drives the first rotating rod 2 to rotate, and the first rotating rod 2 drives the second rotating rod 22 to rotate through the limiting rod 21. At the same time, the second motor can also be started independently, driving the second rotating rod 22 to rotate, thereby realizing the rotation of the first rotating rod 2 and the second rotating rod 22, and thus making the components fixed to them rotate. The telescopic stirring rod 23 and the scraper 231 on the wall rotate together. When the first rotating rod 2 and the second rotating rod 22 rotate, the telescopic stirring rod 23 rotates accordingly, mixing and stirring the carbon dioxide flue gas and absorbent in the tank 1, so that the two come into full contact and promote the full reaction. At the same time, the scraper 231 at the outer end of the telescopic stirring rod 23 adheres closely to the inner wall of the tank 1 during the rotation, scraping and cleaning any carbon and other impurities that may be attached to the inner wall. Since the top and bottom left sides of the telescopic stirring rod 23 are fixedly connected to the side blocks 24, and the outer ends of the side blocks 24 are fixedly connected to the inner wall of the scraper 231 through the spring 241, when the scraper 231 encounters attachments of different thicknesses, the spring 241 will automatically adjust the pressure between the scraper 231 and the inner wall, ensuring that the scraper 231 can always effectively clean the attachments without affecting the cleaning effect due to excessive or insufficient pressure.
[0029] Example 2: Unlike Example 1, through the synergistic action of components such as the annular groove 14 and the insulation body 141, the annular groove 14 is used to install the insulation body 141. The insulation body 141 keeps the internal temperature of the tank 1 warm, preventing energy loss and addressing the issue of poor insulation performance in existing devices. During heat transfer and storage, a large amount of heat is lost to the external environment through the shell, leading not only to energy waste but also to low waste heat recovery efficiency. This prevents the waste heat from fully utilizing its role in the carbon capture and recovery process, thus affecting the overall energy consumption and operational economy of the device. Figure 6 - Figure 7 As shown, the outer wall of the cover plate 11 and the upper part of the outer wall of the tank 1 are both fixedly connected with hanging ears 12, and the hanging ears 12 are threadedly connected with fixing bolts 121. The tank 1 has an annular groove 14, and the heat insulation body 141 is engaged and connected in the annular groove 14. The middle part of the cover plate 11 and the bottom of the tank 1 are both fixedly connected with oil seals 25, and the oil seals 25 are rotatably connected with the first rotating rod 2 and the second rotating rod 22. The right side of the top of the cover plate 11 is connected through an exhaust pipe, and a first solenoid valve is installed on the exhaust pipe. The middle part of the outer wall of the tank 1 is fixedly connected with an air inlet pipe, and a second solenoid valve is installed on the air inlet pipe. The bottom of the right outer wall of the tank 1 is connected through a sewage pipe, and a third solenoid valve is installed on the sewage pipe. The bottom of the tank 1 is fixedly connected with an inclined plate.
[0030] An annular groove 14 is provided on the tank body 1, and an insulation body 141 is engaged and connected within the annular groove 14. The insulation body 141 can effectively prevent the heat inside the tank body 1 from being lost to the external environment, maintain the temperature inside the tank body 1, thereby improving the waste heat recovery efficiency, allowing the waste heat to play a full role in the carbon capture and recovery process, reducing energy waste, and improving the energy consumption performance and operating economy of the device. When it is necessary to clean the inside of the tank body 1, the water pump installed on the water tank at the bottom of the tank body 1 is started. After the water pump starts working, the water in the water tank is transported through the water pipe 13 to the nozzle at the end of the water pipe 13 that passes through the cover plate 11. The water is sprayed out from the nozzle to rinse the inside of the tank body 1, remove residual impurities, and further ensure the cleanliness of the inside of the device. Meanwhile, water can be replaced with absorbent, making the carbon capture and recovery work in tank 1 more comprehensive. For gas treatment, the gas to be treated enters tank 1 through the air inlet pipe in the middle of the outer wall of tank 1. The second solenoid valve on the air inlet pipe can control the opening and closing of the air inlet. The treated gas is discharged from the exhaust pipe on the right side of the top of the cover plate 11. The first solenoid valve on the exhaust pipe controls the opening and closing of the exhaust. When a certain amount of impurities accumulate in tank 1, the third solenoid valve on the sewage pipe at the bottom of the right outer wall of tank 1 is opened. Since the bottom of tank 1 is fixedly connected with an inclined plate, the design of the inclined plate allows impurities to smoothly gather in the sewage pipe, and then be discharged from tank 1 through the sewage pipe, thus completing the discharge of impurities.
[0031] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
