低温多效蒸馏海水淡化技术的发展趋势，必将面临着其装备制造材料的选择问题，在同等条件下，用户自然会倾向于既经久耐用又价格低廉的材料。其中，材料的抗腐蚀问题是很重要的考核指标，如果制造成全尺寸或小尺寸装置进行实物实况模拟，则是费时费力、劳民伤财的不得已的举措。但新材料的使用，不经过实际应用，不拿出具体数据来证明其性能是不可以推广使用的。因此，在这种情况下，迫切需要在试验室建立一种模拟低温多效蒸馏海水淡化装置的试验方法及装置，根据调研，目前国内还没有此项技术，为此，本发明提供一种模拟低温多效蒸馏海水淡化蒸流室环境腐蚀试验方法及装置，用来对蒸流室用材料（特别是蒸馏器用材料）进行试验，得到其在此环境服役中的抗腐蚀性能，为选材提供数据支撑，因为蒸馏室是海水淡化装置的重要部件，其服役环境较恶劣。

The development trend of low-temperature multi-effect distilled seawater desalination technology is bound to face the selection of equipment manufacturing materials. Under the same conditions, users will naturally prefer materials that are both durable and inexpensive. Among them, the corrosion resistance of materials is a very important assessment index. If a full-size or small-size device is manufactured for real-life simulation, it is a last resort measure that is time-consuming, labor-intensive, and labor-intensive. However, the use of new materials cannot be promoted and used without actual application and specific data to prove its performance. Therefore, in this case, it is urgent to establish a test method and device for simulating the low-temperature multi-effect distillation seawater desalination device in the laboratory. According to the investigation, there is no such technology in China. For this reason, the present invention provides a simulation Low-temperature multi-effect distilled seawater desalination steam chamber environmental corrosion test method and device, used to test the materials used in the steam chamber (especially the materials used in the distiller) to obtain the corrosion resistance performance in service in this environment, and provide data for the selection of materials Support, because the distillation chamber is an important part of the seawater desalination device, and its service environment is relatively harsh.
