Embodiment Construction

[0012] Referring to the accompanying drawings, the solar seawater desalination system includes a solar heating device 1 , a steam-water separation device 2 , a condensing device 3 , a water supply device 4 and a temperature increasing heat storage device 5 . The solar heating device 1 includes a frame body 11 and a header 12 and a solar heating pipe 13 arranged on the frame body 11 . The header 12 is installed vertically, that is, the angle between the side of the box connected to the solar heating pipe 13 on the header 12 and the horizontal plane is 90 degrees. The header 12 is elongated, with 25-30 solar heating tubes 13 arranged side by side on the left and right sides of its long side. The inner angle between the solar heating tubes 13 and the long axis of the header 12 is 45-65 degrees. The heating tube 13 is a glass vacuum solar tube, and its tube head is obliquely inserted into the header of the header.

[0013] The upper port of the header is connected with a steam-wa...

Abstract

The invention discloses a solar seawater desalination system, comprising a solar heating device, a steam-water separator, a condensation device, a water supplementing device and a warming and heat-storing device, wherein a header is vertically arranged, a water supplementing outlet of the water supplementing device is communicated with a water inlet of the header, the steam-water separator is arranged between and connected with an upper end opening of the header and the condensation device, a steam separating opening of the steam-water separator is communicated with a steam inlet of the condensation device, and a water supplementing inlet of the water supplementing device is connected with the warming and heat-storing device. The solar seawater desalination system provided by the invention is used for solar seawater desalination and has the characteristics of a fast water circulation speed, rapid heat transfer, long duration of continuous distillation, little influence by weather, good adaptability, etc. Moreover, in the operation process of the system, integral power consumption and energy dissipation are small, operation cost is low, latent heat of cooling of steam is effectively used, and a high utilization rate of solar energy is realized.

Description

technical field [0001] The invention belongs to the technical field of solar desalination of seawater, and in particular relates to a device for desalination of seawater by utilizing solar energy. Background technique [0002] Seawater reserves account for more than 97% of the earth's total water, and obtaining freshwater from seawater has become one of the important ways for human beings to solve the shortage of freshwater. At the same time, solar energy is an inexhaustible green energy source, and the technology of using solar energy to distill seawater for desalination has been highly valued and widely used. However, the common problems of existing solar seawater distillation devices are: first, there are defects in the structure and heating method, not only the temperature rise is slow, but also a considerable part of the energy absorbed by the solar tube is only converted into the sensible heat of seawater in the hot water tank , the proportion of solar energy into sea...
