| Abstract: |
| The work aims to clarify the main sources of atmospheric salt fog, the primary factors affecting the content and distribution of salt fog, the current monitoring technology, and the environmental grades corresponding to the content of salt fog, so as to provide parameter basis for the anti-corrosion design of metal equipment in coastal area. Atmospheric salt fog was prevailingly derived from the marine environment, and the factors affecting the content and distribution of salt fog were mainly the distance from shore, wind speed, wind direction, etc. The primary monitoring techniques of salt fog content were collection and testing. The collection method was one of the important indicators for accuracy. According to the characterization of results (salt fog concentration and salt fog sedimentation rate), it was mainly divided into gas collection and sedimentation collection. The content of salt fog was analyzed by test methods, and then the degree of equipment corrosion was classified. However, those methods have some shortcomings, such as poor data accuracy for human error, and can not get a real-time monitoring, so online detection technology is the main research direction in the future for detection of salt fog content and can accurately the salt fog content in the environment and provide some high efficient and economic advices for the late anti-corrosion. |
