Description

technical field [0001] The invention relates to an in-situ long-term detection system suitable for deep-sea high-temperature hydrothermal fluids. Specifically, its automatic operation is controlled by a microcomputer, and it can perform long-term in-situ detection and A system for performing maintenance and calibration functions on detection electrodes. Background technique [0002] At present, in the exploration of marine resources, the international marine community has carried out research on the detection technology of deep-sea hydrothermal fluids. In seabed hydrothermal vents, the temperature can reach up to 350-400°C. According to traditional detection, the ejected hydrothermal fluid is strongly acidic, highly reducing, and dissolves high concentrations of H. 2 S, heavy metals and other toxic components. 1) Traditional high-temperature hydrothermal detection mostly uses the method of sampling and analysis to observe the change of hydrothermal composition, but due to ...

AI Technical Summary

Problems solved by technology

1) Traditional high-temperature hydrothermal detection mostly uses the method of sampling and analysis to observe the change of hydrothermal composition, but due to the change of the environment in which the sample is collected and stored, its composition will inevitably change, and the analysis data is accurate and not real-time Therefore, in-situ detection technology is the development direction of modern deep-sea scientific research.

2) It is difficult for traditional detection devices and detection electrodes to work stably for a long time under high temperature, and the detection electrodes will fail quickly
