Embodiment approach

[0056]Design a seawater desalination device with an average daily fresh water output of more than 5 tons, and a maximum daily fresh water output of 10 tons. The implementation plan is as follows:

[0057] The solar receiving pool is divided into three levels of pools, occupying a ground with a length of 15 meters and a width of 8 meters. Three platforms are set up on the ground according to the height difference of 0.5 meters, so that the heights of the pools differ from each other by 0.5 meters; the pools are surrounded by concrete, and the steps are located A water level control device and a flow rate regulating device are provided, such as a plurality of limit plates for regulating flow and water level, driven by a motor.

[0058] 3 pools with different height differences can ensure that the first-stage pool on the upper layer is a coarse filtration system, which mainly intercepts impurity particles in the water. The second-stage pool intercepts the precipitation of calcium...

Abstract

This invention provides a solar seawater desalination device. The solar seawater desalination device comprises a vacuum pump, a water inlet pump, a solar receiving pond and a low-temperature multi-stage distillation system. A water outlet of the solar receiving pond is connected with the low-temperature multi-stage distillation system. The solar receiving pond comprises multiple stages of water ponds connected in series, and coated vacuum glass is used for the water ponds so that a ceiling can be formed; intercepting filtering cloth is arranged in the water ponds; the low-temperature multi-stage distillation system comprises multiple stages of low-temperature multi-effect vacuum cabins connected in series; an evaporating and condensing heat exchange plate is horizontally arranged in each cabin, the tail end of each evaporating and condensing heat exchange plate is connected with the vacuum pump, and the two ends of each evaporating and condensing heat exchange plate and the bottom of the corresponding cabin are sealed so that a sealed cavity can be formed; a water passing hole is formed in the lower portion of the connection face of every two cabins; the top of the previous-stage cabin and the bottom of the later-stage sealed cavity are connected with a steam pipe; a fresh water flow-out port is formed in the bottom of each sealed cavity; the vacuum degree of each later-stage cabin is lower than that of the corresponding previous-stage cabin due to the vacuum pump. The technical effects of reducing water making cost and improving water making efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a solar seawater desalination device which uses solar energy as a resource to desalinate seawater. Background technique [0002] Seawater desalination technology refers to a water treatment technology that obtains seawater and removes most of the salts in seawater to make the treated seawater meet the standards of domestic and production water. There are many types of seawater desalination technologies, including "thermal method", "membrane method" and solar energy method; thermal method mainly includes technologies such as multi-effect distillation, multi-stage flash evaporation, compressed air distillation, etc.; membrane method mainly includes reverse osmosis and electrodialysis and other methods. [0003] Thermal and membrane methods are commonly used seawater desalination methods in line with large-scale production at present, but the water production cost of ...
