Embodiment Construction

[0011] The following will be combined with picture Specific embodiments of the present invention will be described. As shown in Figure 1: an energy-saving solar seawater desalination device is provided with a seawater evaporation pool 1, which can be built with bricks, cement, etc., and the bottom of the pool is preferably black to facilitate light absorption. The seawater evaporation pool 1 is provided with a double-sided light-transmitting heat-insulation ceiling 2, and a seawater input pipe 3 is connected to the seawater evaporation pool 1, and a vertical cooling wall 4 is connected to the light-transmitting heat preservation ceiling 2, and the cooling wall 4 can be a single layer of plastic film, the other side of the cooling wall 4 is in contact with the seawater evaporation pool 1. A fresh water collection tank 5 is provided at the junction of the seawater evaporation pool 1, the light-transmitting heat preservation ceiling 2 and the cooling wall 4, and a fresh water ou...

Abstract

The energy-saving solar sea water desalinating device has sea water evaporating pond, transparent heat insulating ceiling, sea water inlet pipe to the sea water evaporating pond, cooling wall between the sea water evaporating pond and the transparent heat insulating ceiling, fresh water collecting sumps in the joint between the evaporating pond and the ceiling and the joint between the evaporating pond and the cooling wall, fresh water outlet pipe connected to the fresh water collecting sumps, and reflecting plate in front of the cooling wall. The reflecting plate, the cooling wall and sea water inlet pipe constitute the condensator to condensate evaporated vapor fast to obtain pure fresh water in greatly lowered cost.

Description

Technical field: [0001] The invention relates to a seawater desalination device, in particular to a solar seawater desalination device which can save electric energy. Background technique: [0002] Although water covers about 3 / 4 of the earth's surface, most of it is sea water, lake water, etc. Because sea water contains a lot of impurities such as salt, it cannot be directly used. Therefore, the fresh water that can be directly used on the earth is less than 2% of the total water. For this reason, people are trying to explore the method of seawater desalination. So far, although a variety of seawater desalination methods have been invented, some use chemical methods to remove impurities in seawater, and some use physical methods to obtain pure fresh water, but all of them have the problem of high desalination costs. In order to solve this problem, the Chinese utility model patent No. 03212404.x discloses a "solar sea water desalination device". The device is provided with...
