| Abstract: |
| The work aims to study the integrated micro-environment control technology and filter equipment against moisture, dust and salts pray, so as to provide technical support for extending the life of island emergency support equipment. The moisture resistance of filter was evaluated by comparing the humidity change at the filter inlet and outlet. The dust resistance was evaluated by testing the change of dust concentration in the natural environment when the filter system was opened or not opened under the test shed. The concentration of salt spray at the front and back end of the filter was collected by suction method to compare its filtration efficiency, and the effect of salt spray concentration on corrosion before and after filtration was characterized by high-precision copper corrosion sheet by reduction method. After the integrated control technology against moisture, dust and salt spray was adopted, the humidity was reduced from 94% to 72%, the dust was reduced to less than 3 mg/m3, the environmental corrosion grade was reduced from G2 to G1, and the salt spray concentration level was reduced from Sc3 to Sc1.The integrated filtration technologyhas excellent moisture, dust and salt spray prevention effects, which can optimize the application environment for the emergency support equipment used in marine service environment and ensure the safe operation. |
