Description

Technical Field

[0001] The utility model belongs to the technical field of desalination, and in particular relates to a regenerated water desalination device. Background Art

[0002] Recycled water, also known as reclaimed water, refers to non-drinking water that has been properly treated to meet certain water quality standards and can be reused within a certain range. When treating sewage, it needs to be pre-treated, secondary treated and deep treated. Deep treatment mainly includes filtration, disinfection, desalination and other links. Desalination is used to remove soluble salts in sewage. However, before the sewage enters the desalination device, the sewage will be transmitted through pipes. However, since the salt in the sewage is not removed, when the sewage flows through the bend in the pipe, due to the change in fluid flow rate, it is easy to form a local supersaturation state, resulting in salt crystallization. These crystals will gradually accumulate, reducing the flow cross-sectional area of ​​the pipe, increasing the resistance of the fluid, and even completely blocking the pipe. In addition, salt crystals attached to the inner wall of the pipe will accelerate the corrosion of the metal pipe and reduce the strength and carrying capacity of the pipe. Utility Model Content
