Description

Technical Field

[0001] This utility model belongs to the field of carbon dioxide treatment technology, and in particular relates to a carbon dioxide capture and testing experimental platform. Background Technology

[0002] Carbon dioxide capture and removal (CO2 capture) is a technology for the efficient separation and recovery of carbon dioxide from industrial emissions, combustion exhaust gases, and the air. It selectively separates CO2 from gas streams through methods such as physical adsorption, chemical absorption, membrane separation, or cryogenic condensation, preventing its direct release into the atmosphere and thus mitigating the greenhouse effect and climate change. This process typically includes gas pretreatment, capture reaction, separation and purification, and subsequent storage or utilization. It can be used in conjunction with high-emission sources such as thermal power plants, steel mills, and cement plants, or deployed in direct air capture systems to ultimately achieve carbon recycling or geological sequestration, providing technological support for carbon neutrality goals. It boasts significant emission reduction and strong sustainability advantages.

[0003] However, existing technologies have some problems: when traditional carbon dioxide supply devices are connected to gas cylinders, experimental operations will cause continuous gas consumption, leading to a rapid decrease in the carbon dioxide reserves inside the cylinders. This forces researchers to frequently replace the cylinders, increasing experimental preparation time and operational burden. In some cases, delays during replacement may even interrupt the continuity of the experiment, affecting the stability and reliability of experimental data, thereby reducing overall experimental efficiency and delaying project progress. Therefore, we propose a carbon dioxide capture and testing experimental platform. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a carbon dioxide capture test experimental platform.

[0005] This invention is implemented as follows: a carbon dioxide capture test experimental platform includes gas tanks for connecting to an external platform body to supply carbon dioxide, and a switching component whose output end is connected to the external platform body. Multiple gas tanks are provided, and their output ends are connected to different input ends of the switching component to achieve multi-source gas supply operation. Specifically, the switching component includes a transmission plate with a first transmission channel and a second transmission channel inside for connecting to different gas tanks. The first and second transmission channels are respectively connected to an output pipe located at the rear of the transmission plate. During gas path control, a frame plate slidably installed inside the transmission plate initially blocks the gas paths of the output pipe and the second transmission channel. When the gas pressure inside the gas tank connected to the first transmission channel is insufficient, the frame plate is moved, connecting the gas path ends of the first transmission channel and the output pipe, and the second transmission channel connects to the output pipe gas path, achieving seamless gas supply switching.

[0006] As a preferred embodiment of this utility model, a hollow channel is provided inside the frame plate, and a through groove provided at the rear of the frame plate connects the output pipe and the hollow channel.

[0007] As a preferred embodiment of this utility model, an air pipe is fixedly connected to the front of the transmission plate, and the upper part of the air pipe is fixedly connected to the transmission plate through a flexible tube, and passes through the first transmission channel.

[0008] In a preferred embodiment of this invention, in the initial state, the piston rod, which is slidably mounted inside the air pipe and driven by the air pressure of the first transmission channel, moves downward. A spring is placed between the piston rod and the bottom of the air pipe. When the air pressure is insufficient, the piston rod returns to its original position. The lower part of the piston rod passes through the transmission plate and is fixedly connected to the frame plate.

[0009] As a preferred embodiment of this utility model, a control valve is fixedly installed on the upper part of each gas tank, and a transmission plug plate is fixedly connected to the output end of the control valve through a transmission pipe, and the transmission plug plate is inserted through the transmission plate.

[0010] In a preferred embodiment of this invention, the control valve includes a screw tube screwed onto the upper part of the gas tank. A hexagonal plate is integrally formed on the upper part of the screw tube. During use, the hexagonal plate and even the screw tube are driven by a wrench to complete the installation. The output end of the bent tube, which is rotatably mounted on the upper part of the screw tube, is fixedly connected to the transmission tube. A knob is fixedly connected to the upper part of a screw rod rotatably mounted on the upper part of the bent tube. The screw rod is slidably mounted inside a shut-off valve block at the lower part of the bent tube. When the shut-off valve block is at its uppermost position, a gas passage opened inside the shut-off valve block connects the input end and the output end of the bent tube.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves continuous, stable, and efficient carbon dioxide supply through the cooperation of multiple gas tanks and a switching component. The gas path of the platform body consists of multiple gas tanks, gas pipes, and a switching component. The gas pipes are connected to the external experimental platform body for gas supply. The output ends of the multiple gas tanks are respectively connected to different input ends inside the switching component, realizing a multi-source parallel supply layout. The switching component is equipped with a transmission plate, which has a first transmission channel and a second transmission channel, respectively connected to different gas tanks, and connected to the output pipe at its rear. A frame plate is slidably installed inside the transmission plate. Its initial position blocks the gas path between the output pipe and the second transmission channel, so that the system supplies gas only from the first gas tank through the first transmission channel during normal gas supply. When insufficient gas pressure is detected in the first gas tank, the frame plate is pushed to move, disconnecting the gas path between the first transmission channel and the output pipe, while opening the gas path between the second transmission channel and the output pipe, realizing seamless access of the second gas tank. The switching process is completed inside the gas circuit, without the need for manual disassembly and reconnection of the gas tubing. This avoids experimental interruptions and CO2 waste caused by changing gas cylinders, ensures continuous gas supply and stable gas pressure, and reduces the frequency of gas cylinder replacement, thereby improving experimental efficiency and data continuity. It is particularly suitable for carbon dioxide capture tests that have high requirements for gas source stability. Attached Figure Description

[0014] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0015] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0016] like Figures 1 to 4 As shown in the figure, the present invention provides a carbon dioxide capture test experimental platform, including a gas tank 1 for connecting to an external platform body to supply carbon dioxide, and a switching component 5 for connecting the output end of the switching component 5 to the external platform body; wherein, multiple gas tanks 1 are provided, and the output ends of multiple gas tanks 1 are connected to different input ends of the switching component 5 to realize multi-source gas supply operation; specifically, the switching component 5 includes a transmission plate 501, and the transmission plate 501 has a first transmission channel 502 and a second transmission channel for connecting to different gas tanks 1. The first transmission channel 502 and the second transmission channel 503 are respectively connected to the output pipe 505 located at the rear of the transmission plate 501. When the air circuit is controlled, the frame plate 504, which is slidably installed inside the transmission plate 501, initially blocks the air circuit of the output pipe 505 and the second transmission channel 503. When the air pressure inside the gas tank 1 connected to the first transmission channel 502 is insufficient, the frame plate 504 is moved, and the air circuit terminals of the first transmission channel 502 and the output pipe 505 are connected. The second transmission channel 503 is connected to the air circuit of the output pipe 505, so as to achieve seamless switching of air supply.

[0017] The aforementioned carbon dioxide capture test platform achieves continuous, stable, and efficient carbon dioxide supply through the cooperation of multiple gas tanks 1 and switching components 5. The air circuit of the main body of the platform consists of multiple air tanks 1 and a switching component 5. The air tanks 1 are connected to the external experimental platform body to supply air. The output ends of the multiple air tanks 1 are respectively connected to different input ends inside the switching component 5 to realize the parallel supply layout of multiple air sources. The switching component 5 has a transmission plate 501 inside. The transmission plate 501 has a first transmission channel 502 and a second transmission channel 503 respectively, which are connected to different gas tanks 1 and are connected to the output pipe 505 at the rear. The frame plate 504 is slidably installed inside the transmission plate 501. Its initial position blocks the gas path between the output pipe 505 and the second transmission channel 503, so that when the system is supplying gas normally, only the first gas tank 1 supplies gas to the outside through the first transmission channel 502. When insufficient gas pressure is detected in the first gas tank 1, the frame plate 504 is moved to disconnect the gas path between the first transmission channel 502 and the output pipe 505, while simultaneously opening the gas path between the second transmission channel 503 and the output pipe 505, achieving seamless connection of the second gas tank 1. This switching process is completed internally within the gas path, eliminating the need for manual disassembly and reconnection of gas tank 1. This avoids experimental interruptions and CO2 waste caused by gas cylinder replacement, ensuring continuous gas supply and pressure stability, while reducing the frequency of gas cylinder replacement, improving experimental efficiency and data continuity. It is particularly suitable for carbon dioxide capture tests that require high gas source stability. In this embodiment, a hollow channel is provided inside the frame plate 504, and a through groove is provided at the rear of the frame plate 504 to connect the output pipe 505 and the hollow channel. An air pipe 506 is fixedly connected to the front of the transmission plate 501. The upper part of the air pipe 506 is fixedly connected to the transmission plate 501 through a flexible hose 507 and passes through the first transmission channel 502. In the initial state, the air pressure of the first transmission channel 502 drives the piston rod 508, which is slidably installed inside the air pipe 506, to move down. A spring 509 is placed between the piston rod 508 and the bottom of the air pipe 506. When the air pressure is insufficient, the piston rod 508 returns to its original position, and the lower part of the piston rod 508 passes through the transmission plate 501 and is fixedly connected to the frame plate 504.

[0018] Automatic air supply switching is achieved through pneumatic drive and mechanical linkage. The frame plate 504 has a hollow channel inside, and its rear slot is connected to the output pipe 505, so that the change of the position of the frame plate 504 directly affects the output air path. The front part of the transmission plate 501 is fixedly connected to the air pipe 506. The air pipe 506 is connected to the first transmission channel 502 through the hose 507. In the initial state, the air pressure generated by the air supplied by the first air tank 1 pushes the piston rod 508, which is slidably installed inside the air pipe 506, to move downward and compress the spring 509 located between the piston rod 508 and the bottom of the air pipe 506, so that the frame plate 504 is kept in the state of blocking the second transmission channel 503 and opening the first transmission channel 502. When the air pressure of the first gas tank 1 drops below the set threshold, the air pressure is insufficient to maintain the downward movement of the piston rod 508. The spring 509 rebounds and drives the piston rod 508 to move upward. Its lower end passes through the transmission plate 501 and is fixedly connected to the frame plate 504, thereby pushing the frame plate 504 to the position of blocking the first transmission channel 502 and opening the second transmission channel 503, realizing the automatic connection of the second gas tank 1 and completing the seamless switching of the air source.

[0019] In this embodiment, a control valve 2 is fixedly installed on the upper part of each gas tank 1. The output end of the control valve 2 is fixedly connected to a transmission plate 4 through a transmission pipe 3. The transmission plate 4 is inserted into a through transmission plate 501. The control valve 2 includes a screw tube 202 screwed to the upper part of the gas tank 1. A hexagonal plate 203 is integrally formed on the upper part of the screw tube 202. During use, the hexagonal plate 203 and even the screw tube 202 are installed by driving a wrench. The output end of the bent pipe 201 installed on the upper part of the screw tube 202 is fixedly connected to the transmission pipe 3. A knob 204 is fixedly connected to the upper part of the screw rod 205 installed on the upper part of the bent pipe 201. The screw rod 205 is slidably installed inside the cut-off valve block 206 at the lower part of the bent pipe 201. When the cut-off valve block 206 is at the uppermost position, the gas channel 207 opened inside the cut-off valve block 206 connects the input end and the output end of the bent pipe 201.

[0020] The opening and closing of the air circuit is controlled by mechanical rotation and sliding of the valve block, and easy installation is achieved.

[0021] Each gas tank 1 is fixedly equipped with a control valve 2. The output end of the control valve 2 is connected to the transmission plate 4 via the transmission pipe 3. The plate is inserted into and passes through the transmission plate 501, so as to realize the detachable connection between the gas source and the switching component 5.

[0022] The control valve 2 body is composed of a screw tube 202 screwed to the upper part of the gas tank 1. A hexagonal plate 203 is integrally formed on the upper part of the screw tube 202. During installation, the hexagonal plate 203 can be rotated by a wrench, thereby driving the screw tube 202 to be screwed into or out of the gas tank 1 interface, completing quick installation and removal.

[0023] A bent tube 201 is rotatably mounted on the upper part of the solenoid 202, and its output end is fixedly connected to the transmission tube 3, which is used to change the direction of the air path and connect with external components.

[0024] A lead screw 205 is rotatably mounted on the upper part of the bent pipe 201. A knob 204 is fixedly connected to the upper end of the lead screw 205. The user can drive the lead screw 205 to rotate by rotating the knob 204, thereby causing the shut-off valve block 206 screwed to the lower part of the lead screw 205 to slide along the axial direction of the bent pipe 201.

[0025] When the shut-off valve block 206 is at its uppermost position, its internal gas passage 207 is connected to the input and output ends of the bend pipe 201, allowing free gas flow. When the knob 204 is rotated in the opposite direction to move the valve block down, the internal passage is closed, cutting off the gas path, thereby achieving on / off control and safety isolation of the carbon dioxide supply.

[0026] The working principle of this utility model: In use, the multi-gas tank 1 and the switching component 5 work together to achieve a continuous, stable, and efficient supply of carbon dioxide. The gas path of the platform body consists of multiple gas tanks 1, gas pipes 506, and the switching component 5. The gas pipes 506 are connected to the external experimental platform body for gas supply. The output ends of the multiple gas tanks 1 are respectively connected to different input ends inside the switching component 5 to realize a multi-gas source parallel supply layout. The switching component 5 is equipped with a transmission plate 501. The transmission plate 501 has a first transmission channel 502 and a second transmission channel 503 respectively, which are connected to different... Gas cylinder 1 is connected to the output pipe 505 at its rear. A frame plate 504 is slidably installed inside the transmission plate 501. Its initial position blocks the gas path between the output pipe 505 and the second transmission channel 503, ensuring that during normal gas supply, only the first gas cylinder 1 supplies gas through the first transmission channel 502. When insufficient gas pressure is detected in the first gas cylinder 1, the frame plate 504 is pushed to disconnect the gas path between the first transmission channel 502 and the output pipe 505, while simultaneously opening the gas path between the second transmission channel 503 and the output pipe 505, achieving seamless connection of the second gas cylinder 1. This switching process is completed within the gas path, eliminating the need for manual disassembly and reconnection of the gas pipe 506, thus avoiding experimental interruptions and CO2 waste caused by changing gas cylinders, and ensuring continuous gas supply and stable gas pressure.
