Problems solved by technology

The main disadvantage of the seawater desalination method and device: the device and method mainly focus on the design of the seawater desalination process, and do not design the corresponding flash evaporation and condensation for the characteristics of small temperature difference, low air pressure, and large flow rate in the seawater desalination process of temperature difference energy device, which leads to problems such as incomplete condensation, insufficient vacuum and unsustainable flash condensation process in the entire process

Abstract

The invention discloses a flash-evaporation and condensation integrated seawater desalinization device, comprising an upper oval sealing head (12), a cylinder body (8), a lower oval sealing head (1) and the like, wherein the upper oval sealing head (12) and an upper pipe plate (10) are enclosed to form an upper deep layer seawater chamber (14), and the lower oval sealing head (1) and a lower pipe plate (3) are enclosed to form a lower deep layer seawater chamber (21); the cylinder body (8) is internally provided with a condensation chamber (7) and a flash-evaporation chamber (18) which are communicated by a steam channel (15); the condensation chamber (7) is internally provided with a finned type heat exchange pipe component (9) which is respectively communicated with the upper deep layer seawater chamber (14) and the lower deep layer seawater chamber (21); and the upper deep layer seawater chamber (14), the lower deep layer seawater chamber (21), the condensation chamber (7) and the flash-evaporation chamber (18) are respectively provided with an external interface. The flash-evaporation and condensation integrated seawater desalinization device is used for desalinating seawater, thereby reducing the steam pressure drop of flash evaporation.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to a flash evaporation seawater desalination device suitable for seawater desalination by using ocean temperature difference. Background technique [0002] Seawater desalination is a resource-intensive industry with an average energy consumption of 2-4kwh / m 3 . As the scale of seawater desalination continues to expand, its energy consumption has also begun to increase dramatically. Therefore, seeking cheap and clean new energy to replace traditional energy for seawater desalination will bring huge economic value. [0003] Ocean temperature difference energy is an important part of renewable energy, and it is also the energy with the largest reserves and the most stable energy in ocean energy. In tropical seas, the temperature of surface seawater is maintained at about 24-33°C all year round, and the temperature of deep seawater at 500-1000m is maintained at about 3-9°C all year r...
