Abstract

The invention discloses a continuous type seawater freezing-desalinization device. The continuous type seawater freezing-desalinization device comprises a hot-air blower, a sprayer, a porous crawler,a seawater freezing crystallizer, a coolant outlet, a coolant inlet, a driving device, a seawater pump, a seawater tank, a concentrated seawater collecting tank, a concentrated seawater tank, a washing water collecting tank, a fresh water collecting tank, a fresh water tank and a fresh water pump. Seawater is crystallized by the seawater freezing crystallizer, then, ice crystals and concentrated seawater are separated by the porous crawler, the concentrated seawater enters the concentrated seawater tank through the concentrated seawater collecting tank, the ice crystals are washed through thesprayer, washing water and seawater in the seawater tank enter the seawater freezing crystallizer together through the seawater pump, and the washed ice crystals are melted into fresh water through hot air blown from the hot-air blower. The device is high in integration level, the requirements on different fresh water volumes and fresh water qualities can be met, and continuous industrial production is easy to achieve.

Description

technical field [0001] The patent of the present invention relates to the field of seawater desalination devices, in particular to a continuous seawater freezing and desalination device. Background technique [0002] As an effective method to solve the shortage of fresh water resources, seawater desalination has developed rapidly in the past ten years, mainly including membrane separation method, distillation method and freezing method. Due to the large-scale use of LNG in recent years, the cold energy released by LNG has been Widely used in seawater desalination by freezing method, freezing method has become a kind of seawater desalination method with broad application prospects. [0003] The desalination of seawater by freezing method generally freezes part of the seawater through a crystallizer, such as patent 201610056567.X, and then separates the ice crystals from the concentrated seawater, washes the ice crystals, and melts the ice crystals to obtain fresh water. In t...
