Solar-powered seawater desalination plant and high-concentration seawater separator

Abstract

The invention discloses a solar-powered seawater desalination plant and a high-concentration seawater separator. The seawater desalination plant comprises a cover body with an opening facing downwards. The lower edge of the cover body is provided with a water collecting sump with its outer edge connected with the inner wall of the cover body. The seawater desalination plant also comprises a drive unit and fan blades which are arranged inside the cover body and connected to the drive unit. The fan blades are driven by the drive unit to rotate, thus centrifuging water vapor inside the cover body onto the inner wall of the cover body. The surface of the fan blades is provided with grooves; rotation axis of the fan blades is vertically arranged; and the direction of the grooves is from the rotation axis of the fan blades towards the outside and gradually downwards. By additionally arranging a water plate in the seawater desalination plant, the high-concentration seawater separator is formed. The invention is not dependent on manpowered energy for seawater evaporation and recovery. Meanwhile, the device of the invention also can be used in collection of high-concentration seawater as well as extraction of salt, and has advantages of good aggregating effect, high efficiency and low cost.

Description

technical field [0001] The invention relates to a device for collecting fresh water evaporated from seawater, and also relates to a seawater separation device based on the seawater desalination device. Background technique [0002] At present, seawater distillation is the main means to achieve seawater desalination. However, most distillation-based desalination methods rely on heat sources, and large-scale concentrated distillation needs to be artificially provided with large heat energy. Moreover, the distilled fresh water needs to be collected by a special device, and the operation of the collection device still depends on the energy provided by manpower. Contents of the invention [0003] The present invention proposes a seawater desalination device using solar energy and a seawater separation device based on the seawater desalination device, the purpose of which is to realize evaporation and collection of seawater without relying on artificially provided energy.
