Embodiment 1

[0053] Specific embodiment 1 of novel solar energy seawater desalination and water purification system of the present invention, as figure 1shown. The new solar desalination and water purification system includes a flexible thermal insulation material 1, a fixed thermal insulation wall 11 facing north, a rotatable thermal insulation wall 12 facing west, a rotatable thermal insulation wall 13 facing south, a rotatable thermal insulation wall 14 facing east, and a light transmission system 2 , heat collector 31, evaporator 4, heat exchanger 41, heat exchanger 42, heat exchanger 43, pump 44, vacuum pump 45, valve 46, heat exchanger 47, water storage tank 5, heat storage system 7.

[0054] When the sun shines, the flexible insulation material 1 is rolled up, and the south-facing rotatable insulation wall 13, the east-facing rotatable insulation wall 14 and the west-facing rotatable insulation wall 12 are rotated to a suitable position and fixed. At night or when there is no sunli...

Embodiment 2

[0061] Specific embodiment 2 of novel solar desalination and water purification system of the present invention, as Figure 9 shown. On the basis of Example 1, different from Example 1, the novel solar desalination and water purification system uses multi-stage flash evaporation to generate fresh water or purified water, and the system consists of 3 flash chambers.

[0062] In heat storage system 7, seawater or water to be purified that has absorbed heat to a certain temperature is introduced into the first-stage flash chamber, hot seawater or hot water to be purified is superheated to generate steam, and the temperature of the hot seawater or water to be purified is reduced after flash evaporation , enter the second-stage flash chamber through the valve, generate steam in the second-stage flash chamber, the temperature of seawater or water to be purified is further reduced, and enter the third-stage flash chamber 8 through the valve to flash to generate steam, the first The ...

Embodiment 3

[0064] Specific embodiment 3 of novel solar desalination and water purification system of the present invention, as Figure 9 shown. The difference from Example 1 and Example 2 is that this novel solar desalination and water purification system adopts the method of solar direct distillation, and seawater or water to be purified is placed in the heat storage tank 7, and on the surface of seawater or water to be purified Place materials with high heat absorption rate to fully absorb solar radiation energy. Part of the water vapor generated by heating seawater or water to be purified is condensed on the inner surface of the light transmission system and the inner surface of the north-facing fixed wall, collected by the water tank, and part of the water vapor is blown by the fan 53 out, heat release and condensation in the heat exchanger 52 in the condenser 51, and the condensed steam enters the water storage tank 5, and the latent heat of condensation of the steam heats the seawa...

Abstract

The invention relates to a seawater desalination and water purification system, and especially relates to a novel high-efficiency solar seawater desalination system and solar water purification system. The novel system comprises an external heat insulation system, a light transmission system, a heat collection system, a heat storage system, a seawater desalination device (water purification device), and auxiliary devices (mainly including an auxiliary energy devices, valves and pumps). Seawater desalination or sewage purification is directly or indirectly carried out by optimizing system design and constructing the high-efficiency solar heat collection system and the heat storage system, and energy is supplied by an air source, a water source, a ground source heat pump and other renewable energy or fossil energy when sunshine is insufficient. The system of the invention utilizes solar energy resources, land resources and marine resources reasonably and efficiently, improves the water production efficiency of seawater desalination and water purification, improves the reliability of the seawater desalination and water purification systems, and provides an efficient, green and environmentally-friendly way for large-scale desalination and water purification.

Description

technical field [0001] The application of the present invention relates to seawater desalination and water purification systems, in particular to novel high-efficiency solar seawater desalination systems and solar water purification systems. Background technique [0002] Water is the cradle of life, an indispensable basic material for human production and life, and an irreplaceable and precious basic natural resource. The shortage of water resources has become a global crisis, and the use of seawater desalination technology to increase fresh water supply has become an important way for countries all over the world to solve the water crisis. my country's total water resources rank among the top in the world, but the per capita water resources are less than 2,400 cubic meters, which is only about 25% of the world's average level. It is listed by the United Nations as one of the most water-poor countries. my country's coastal areas are densely populated, economically developed...
