Embodiment 1

[0042] A land-based solar capillary evaporation seawater desalinator with a fresh water output of 1 kg / h is equipped with five activated carbon fiber capillary evaporators evenly installed in a light-transmitting sealed desalinator box with a length of 2.5m, a width of 2.5m, and a height of 600mm. The thickness is 7mm, the length is 2.3m, and the height is 500mm. A fresh water condensation plate is installed between each adjacent two activated carbon fiber capillary evaporators. It is 2.3m long, 500mm high, and 2mm thick. The condensation plate is fixed at a thickness of 10mm. Plastic middle plate. The lower end of each capillary evaporator is provided with a 100mm high concentrated brine collection tank, and there is a small hole in the tank, which is connected to the concentrated brine outlet. The sea water distribution pipe is installed in the desalinator box, and extends vertically through the middle plate into the cooling tank. One end of the cooling tank has a seawater ...

Abstract

A land-type solar seawater desalinating apparatus with capillary evaporation function is composed of seawater tube, seawater pump, seaweed removing unit, fresh water condensing plate and its cooling trough, capillary evaporator, sealed transparent casing, seawater distributing tube, concentrated saline collector, fresh water collector, etc.

Description

technical field [0001] The invention belongs to the technology and equipment for using the principle of capillary action to increase the evaporation surface so as to realize the desalination of seawater by solar energy. Background technique [0002] As we all know, almost all the water on the earth is stored in the ocean, relying on the evaporation of solar energy to transform the seawater into gaseous clouds and transport them to the land area, and finally fall to the ground in the form of rain and snow, becoming the surface water of rivers and lakes and the water that penetrates underground. groundwater. Due to the influence of various natural factors, the distribution of fresh water resources on the earth is very uneven in time and space, and water shortages and floods will occur in different regions and at different times in the same region. Especially in coastal areas, most of the fresh water resources are very scarce, how to implement seawater desalination is one of t...
