Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of carbon dioxide detection, and particularly relates to a carbon dioxide detection device with a cleaning function. BACKGROUND

[0002] Currently, carbon dioxide needs to be detected in the process of carbon dioxide transportation. A detection device is usually connected in a transportation pipeline. The detection range includes temperature, pressure and the like. The parameter changes of carbon dioxide need to be grasped in real time. However, carbon dioxide carries dust and impurities in the transmission process. The main sources of the dust and impurities include: (1) the inner walls of metal containers such as transportation tankers, storage tanks and gas cylinders may be corroded due to long-term use, generating metal oxide particles (rust and the like). Under the scouring of the fluid in the filling and discharging process, these particles may fall off and mix into the carbon dioxide; (2) the mechanical parts of pumps, compressors, valves and pipelines may generate tiny metal or plastic wear particles when in operation; (3) if the transportation tankers or movable storage tanks are not subjected to strict cleaning and purging procedures, the residual materials of the previous transportation may contaminate the carbon dioxide in the current transportation; (4) if the cleanliness of the operating environment is poor, or the dust and impurities in the outside world may be brought into the system when the pipeline is connected / disconnected.

[0003] When the detection device is used for a period of time, the dust and impurities may gradually adhere to the inner wall of the detection device, which may cause errors in the measurement of temperature and pressure.
