Technical Field

[0001] This utility model relates to the field of performance testing technology, and in particular to a carbon dioxide adsorbent performance testing device. Background Technology

[0002] Carbon dioxide (CO2) adsorbents (such as molecular sieves and amine-functionalized materials) are core materials for industrial emission reduction and air purification in confined spaces (submarines, space stations). Their adsorption performance (capacity, rate, and selectivity) directly determines the efficiency of CO2 capture and purification. To promote the research and development and quality control of adsorbents, it is necessary to efficiently test their performance.

[0003] However, existing carbon dioxide adsorbent performance testing devices have cumbersome disassembly and assembly procedures, lack quick disassembly and assembly structures, and take a long time to replace the adsorbent. It is difficult to efficiently compare the performance of adsorbents with different formulations. Therefore, a disassembled, multi-station, and well-sealed CO2 adsorbent performance testing device is needed. Utility Model Content

Therefore, this invention proposes a carbon dioxide adsorbent performance testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carbon dioxide adsorbent performance testing device, comprising a U-shaped plate, wherein one side wall of the U-shaped plate is fixedly connected to a connecting pipe at equal intervals, and the other side wall of the U-shaped plate is fixedly connected to an outlet pipe at equal intervals. Carbon dioxide detection sensors are installed on the surface of the outlet pipe. Telescopic tubes are fixedly connected to both inner walls of the U-shaped plate at equal intervals. A disc is fixedly connected to the other end of the telescopic tube. The surface of the disc has convex holes at equal intervals. Cylinders are provided at equal intervals between the discs. Both ends of the cylinders are embedded in the convex holes. Electric push rods are fixedly connected through and near the center of both inner walls of the U-shaped plate. The output end of the electric push rod is fixedly connected to the disc.

[0006] Preferably, mounting blocks are fixedly connected to both sides of the U-shaped plate and near both ends, and mounting holes are provided on the surface of each mounting block.

[0007] Preferably, the telescopic tube is connected to the connecting pipe and the air outlet pipe, and the convex hole is connected to the telescopic tube.

[0019] The overall effect of Embodiment 1 is as follows: a pipe 3 is fixed and connected at equal intervals on one side wall of the U-shaped plate 1, and an outlet pipe 4 is fixed and connected at equal intervals on the other side wall of the U-shaped plate 1, which can achieve the effect of carbon dioxide inlet and outlet. Carbon dioxide detection sensors 5 are installed on the surface of the outlet pipe 4, which can detect carbon dioxide. Telescopic pipes 6 are fixedly connected at equal intervals on both inner walls of the U-shaped plate 1, and a disc 7 is fixedly connected to the other end of the telescopic pipe 6. The surface of the disc 7 is provided with convex holes 8 at equal intervals. Cylinders 12 are provided at equal intervals between the discs 7, and both ends of the cylinders 12 are embedded in the convex holes 8. Electric push rods 13 are connected through and fixedly connected to both inner walls of the U-shaped plate 1 near the center. The output end of the electric push rod 13 is fixedly connected to the disc 7, which can achieve the effect of the electric push rod 13 pushing the disc 7 to clamp and fix the cylinder 12.

[0020] Example 2, as Figure 1-4 As shown, mounting blocks 2 are fixedly connected to both sides of the U-shaped plate 1 near both ends, and mounting holes are opened on the surface of each mounting block 2; the telescopic pipe 6 is connected to the connecting pipe 3 and the air outlet pipe 4, and the convex hole 8 is connected to the telescopic pipe 6; the inside of each convex hole 8 is fixedly connected to a ring gasket 9; both ends of the cylinder 12 are embedded and installed with L-shaped ring plates 10, and the surface of the ring gasket 9 is attached to one end of each L-shaped ring plate 10; the inside of each L-shaped ring plate 10 is fixedly connected to a filter disc 11; a control panel 14 is fixedly installed on one side wall of the U-shaped plate 1 near one bottom corner.

[0021] The overall effect of Embodiment 2 is as follows: Mounting blocks 2 are fixedly connected to both sides of the U-shaped plate 1 near both ends, and mounting holes are provided on the surface of each mounting block 2 to secure the U-shaped plate 1; the telescopic tube 6 connects to the connecting pipe 3 and the air outlet pipe 4, and the convex hole 8 connects to the telescopic tube 6, allowing the gas to pass through the telescopic tube 6 via the connecting pipe 3; ring gaskets 9 are fixedly connected inside each convex hole 8 to seal both ends of the cylinder 12; L-shaped ring plates 10 are embedded and installed at both ends of the cylinder 12, with the surface of the ring gasket 9 adhering to one end of each L-shaped ring plate 10, and filter discs 11 are fixedly connected inside each L-shaped ring plate 10 to prevent the adsorbent from falling from both ends of the cylinder 12; a control panel 14 is fixedly installed on one side wall of the U-shaped plate 1 near one bottom corner to control the device.

[0022] Working principle: Before testing, the CO2 adsorbent to be tested is filled into the cylinder 12 to ensure that the filter disc 11 effectively intercepts the adsorbent particles. The electric push rod 13 is activated via the control panel 14, pushing the disc 7 towards the center of the U-shaped plate 1, causing both ends of the cylinder 12 to embed into the convex holes 8 of the disc 7. At this time, the L-shaped ring plate 10 and the ring gasket 9 inside the convex hole 8 are tightly fitted, achieving a sealed connection between the cylinder 12 and the telescopic tube 6. Subsequently, the CO2 mixture enters the telescopic tube 6 through the connecting pipe 3 and flows through the convex hole 8. After the gas enters the cylinder 12 and comes into full contact with the adsorbent inside, it flows from the convex hole 8 and telescopic tube 6 at the other end of the cylinder 12 to the outlet pipe 4. The carbon dioxide detection sensor 5 on the surface of the outlet pipe 4 detects the CO2 concentration in the gas in real time. By comparing the CO2 concentration at the inlet and outlet, the adsorption performance of the adsorbent is calculated. After the test is completed, the electric push rod 13 drives the disc 7 to move to both sides of the U-shaped plate 1, so that the cylinder 12 is separated from the convex hole 8. The cylinder 12 can then be removed to replace or clean the adsorbent for the next round of testing.

[0023] The wiring diagrams of the carbon dioxide detection sensor 5 and control panel 14 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the carbon dioxide detection sensor 5 and control panel 14 will not be explained in detail.
