目的 研发防潮防尘防盐雾一体化微环境控制技术与过滤设备，为延长海岛应急保障设备寿命提供技术支撑。方法 通过对比过滤器入口与出口湿度的变化情况，评估其防潮性。在试验棚下测试开启和未开启过滤设备过程中灰尘浓度的变化情况，测试其防尘性。利用吸气法采集过滤器前后端盐雾浓度，对比其过滤效率。利用高精度铜腐蚀片还原法，表征过滤前后盐雾浓度对腐蚀性的影响情况。结果 采用防潮防尘防盐雾一体化控制技术后，相对湿度由94%降至72%，粉尘质量浓度降低至3 mg/m³以下，环境腐蚀等级由G2降至G1，盐雾浓度水平由Sc3降至Sc1。结论 防潮防尘防盐雾一体过滤技术具有良好的防潮、防尘以及防盐雾效果，可为海洋服役环境下的应急保障设备优化使用环境，保障其安全运行。

Integrated Micro-environment Control Technology and Performance Verification of Island Emergency Support Equipment Against Moisture, Dust and Salt Spray

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.
