目前海水淡化技术超过20余种，包括冷冻法、反渗透法、低温多效、多级闪蒸、电渗析法、 压汽蒸馏、露点蒸发法、水电联产、热膜联产以及利用核能、太阳能、风能、潮汐能海水淡化技 术等等，以及微滤、超滤、纳滤等多项预处理和后处理工艺。

从大的分类来看，主要分为蒸馏法(热法)和膜法两大类，其中低温多效蒸馏法、多级闪蒸法和反渗 透膜法是主流技术。

一般而言，低多效具有节能、海水预处理要求低、淡化水品质高等优点;

反渗透膜法具有投资低、能耗低等优点，但海水预处理要求高;

多级闪蒸法具有技术成熟、运行可靠、装置产量大等优点，但能耗偏高。

一般认为，低多效蒸馏法和反渗透膜法是未来方向。

海水处理意味着靠近海边，潮湿的海风以及含盐量比较高的海水对海水处理设备有着*的要求 ：耐腐蚀!特别是自己接和海水接触的管道配件--柔性软接头!

近海的环境，近乎于盐雾环境，那么在盐雾环境下应该如何选择橡胶接头的类型?

柔性软接头的选择需要考虑工作环境和管道介质。

??

海水处理限制了柔性软接头的橡胶材质必须酸碱：三元乙丙橡胶!

海水环境限制了橡胶接头法兰的选择：304!

304法兰三元乙丙柔性软接头特点：

1.特殊法兰，耐腐蚀，特别是在海水环境下，经久耐用;

2.三元乙丙橡胶，耐弱酸弱碱，用于海水处理毫无压力;

3.体积小、重量轻、弹性好、安装维修方便。

4.安装后可吸收管道震动产生的横向、轴向、角向位移;不受管道不同心，法兰不平行的限制。

The global desalination technology for more than 20 species, including freezing method, reverse osmosis, low-temperature multi effect, multi stage flash, electric dialysis method, pressure steam distillation, dew point evaporation, water and electricity production, hot film co production and use of nuclear energy, solar energy, wind energy, tidal can desalination technologies and microfiltration, ultrafiltration, nanofiltration and other several pre-processing and post-processing technology.

From the point of view of the classification of large, mainly divided into distillation (thermal) and membrane method, the low temperature multi effect distillation, multi-stage flash distillation method and reverse osmosis membrane method is the world's mainstream technology.

Generally speaking, low multi effect has the advantages of energy saving, low water pretreatment requirements, low water quality and high quality;

The reverse osmosis membrane method has the advantages of low investment and low energy consumption;

The multi-stage flash method has the advantages of mature technology, reliable operation, large output device, but high energy consumption.

It is generally believed that the low multiple effect distillation and reverse osmosis membrane are the future directions.

Seawater treatment means that close to the beach, moist sea breeze and the salt content of water of sea water processing equipment has a high requirement: corrosion. Especially their connection and contact with seawater pipe fittings, flexible connector!

Offshore environment, almost in the salt fog environment, then in the salt fog environment should be how to choose the type of rubber joints?

The choice of flexible flexible joints should be considered in the working environment and pipeline medium.

Seawater treatment limits the flexible connector of the rubber material must be acid: three epdm!

The seawater environment limits the choice of the flange of the rubber joint: 304!
