[0027] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0028] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] This utility model provides, for example Figures 1-5 The carbon dioxide delivery pipeline structure shown includes a main pipe frame 1, characterized in that: a monitoring and pressure relief mechanism 2 is fixedly connected to the top surface of the main pipe frame 1, the main pipe frame 1 includes a delivery pipe 101, flanges 102 are fixed at both ends of the delivery pipe 101, an insert ring 103 is fixed at one end of the flange 102, and a rubber ring 104 is attached to the outer wall of the insert ring 103.

[0030] To maintain the stable connection between this pipeline conveying structure and the overall conveying pipeline, such as Figure 1As shown, this conveying pipeline structure is connected to the long-distance conveying pipeline by conveying pipe 101 and flanges 102 fixed at both ends. The connection is stable with the bolts around flange 102. At the same time, the insert ring 103 maintains the snap-fit ​​combination during connection, and the fitted rubber ring 104 maintains the stable airtightness of the docking.

[0031] like Figures 2-5 As shown, the pressure relief monitoring mechanism 2 includes a pressure relief housing 201. A pressure sensor 202 is embedded in one side of the bottom of the pressure relief housing 201. A pressure relief pile 203 is connected to one side of the top of the pressure sensor 202 via a wire. A servo motor 204 is fixed to the top of the pressure relief pile 203. A controller 205 is fixed to one side of the bottom of the servo motor 204. A communication module 206 is fixed to the other side of the bottom of the servo motor 204. A threaded rod 207 is fixed to the shaft at the bottom of the servo motor 204. A sleeve is threadedly connected to the bottom of the threaded rod 207. The bottom end of the tube 208 and the sleeve 208 is fixed with a pressure relief head 209. A groove 210 is opened on one side of the outer wall of the pressure relief head 209. An air inlet 211 is passed through the center of the bottom end of the pressure relief head 209. Exhaust holes 212 are distributed on both sides of the air inlet 211. A first detection contact 213 is attached to the other side of the outer wall of the pressure relief head 209. A second detection contact 214 is provided on the top of the first detection contact 213. Exhaust pipes 215 are fixed on both sides of the outer wall of the pressure relief pile 203. A filter frame 216 is engaged at the end of the exhaust pipe 215.

[0032] To provide adjustability of the overall pipeline delivery structure during pressure relief, such as Figures 2-5 As shown, during the depressurization process, the threaded rod 207 and sleeve 208 connected to the bottom shaft of this carbon dioxide conveying pipeline structure can be adjusted by the servo motor 204, so that the depressurization head 209 fixed at the bottom of the sleeve 208 slides upward. This allows the exhaust holes 212 on both sides of the depressurization head 209 to be aligned with the exhaust pipe 215 in sequence, so that the carbon dioxide pressure inside the pipeline can be discharged through the exhaust pipe 215. By connecting multiple sets of exhaust holes 212 with the exhaust pipe 215, the purpose of single-set depressurization and multiple sets of synchronous depressurization can be achieved, thereby controlling the depressurization process and providing controllability and stability of the depressurization and discharge process.

[0033] Before the pressure relief process, the aforementioned pipeline structure can be monitored in real time inside the conveying pipeline by a pressure sensor 202 fixed at the bottom of the pressure relief shell 201. When the pressure is abnormal, the servo motor 204 can be adjusted and the pressure relief can be regulated by the controller 205 connected by wires. At the same time, the first detection contact 213 and the second detection contact 214 on the same axis can be used to determine whether the exhaust holes 212 and exhaust pipes 215 on both sides of the pressure relief head 209 are properly connected when the pressure relief head 209 is depressurized by whether the detection contacts are released. The monitoring information of the contacts and the pressure sensor 202 can be remotely transmitted through the connected communication module 206, which makes it convenient for maintenance personnel to keep abreast of the conveying status.

[0034] In summary, when using this carbon dioxide delivery pipeline structure, the flanges 102 at both ends of the delivery pipe 101 are first connected to the overall delivery pipeline structure, and then fixed in place with bolts and other fasteners. After being put into use, when the internal delivery pressure reaches a certain threshold, it is detected by the pressure sensor 202, which then transmits the information to the controller 205. The controller 205 then transmits the monitored pressure information to the communication module 206, which transmits the monitored pressure information in real time. Simultaneously, the controller 205 controls the servo motor 204... The servo motor 204 drives the threaded rod 207 connected to the bottom shaft, which in turn drives the sleeve 208 connected to the bottom, causing the sleeve 208 and the pressure relief head 209 fixed at the bottom to slide and adjust along the inner wall of the pressure relief pile 203. This allows the vent holes 212 on both sides of the pressure relief head 209 to gradually align with the vent pipe 215. When the first set of vent pipes 215 aligns with the vent holes 212, the pressure relief head 209 slides to contact the first detection contact 213, and simultaneously transmits the trigger information in conjunction with the communication module 206. This allows the operator to maintain control over the pressure adjustment and pressure relief process.
