Description
Technical field
The present invention relates to the self-produced fresh water planting units of solar energy that one kind can directly be irrigated with seawater.It can be carried out using the sun
Sea water desalination is simultaneously applied to agricultural planting engineering, belongs to Salar light-gathering and utilizes and novel agricultural facility technology field.
Background technique
The many areas in the world all have that freshwater resources and land resource critical shortage, crop irrigation occupy ground
70% freshwater resources on ball, and it is increasingly prominent to irrigate nervous deficient problem, if sea water desalination can be can be carried out using the sun, side
Just the crop growth for efficiently producing fresh water and supplying nearby, not only solves the problems, such as shortage of fresh water, but also can solve tight with agricultural land
Difficulty is opened, that will realize people to the longing of Marine agriculture engineering.
On the other hand, can be carried out sea water desalination using the sun can both save a large amount of traditional energies, and it is dirty also to can avoid environment
Dye, therefore the method that the unremitting pursuit of people can be carried out sea water desalination using the sun.Nearly one over 100 years, people to using solar energy into
Row sea water desalination is made that great efforts, however, desalination with Solar Energy is still unable to large-scale promotion utilization so far, it is former
Economy because being it can not compare favourably at present with traditional industrialization seawater desalination system.
Analysis shows the main reason for causing solar seawater desalination economic cost excessively high has: (1) traditional solar energy sea water
Desalination system is mainly made of solar thermal collector, thermal storage device and desalination apparatus three parts, and the pipe of tediously long pipeline is needed between three
Road is connected with each other, and causes heat transmission resistance big and pipeline heat loss increases, cause overall system efficiency not high.(2) solar energy heating
The construction cost of system is excessively high.According to analysis, solar seawater desalination system has about 80% cost to come from solar thermal collector
End.(3) solar thermal collection system takes up a large area, and cost of floor space is high, this place in short supply to land resource is particularly disadvantageous, also increases
The management cost of system is added.Therefore, solar thermal collector and fresh-water generator are combined as a whole, omit many intermediate links
Solar seawater desalination system be a good thinking.
For the seawater irrigation of agriculture project, many trials are had been carried out in researcher, but people's development at this stage
Marine agriculture thinking is confined to crops how to be made to receive seawater directly to fill, or kind on the ship in ocean and offshore land
It plants plant and desalting plant is installed to obtain fresh water.But not all plant can receive seawater and directly fill, and at offshore
Traditional seawater desalination system is arranged, and not only land occupation resource is also required to interminable transfer pipeline fresh water is transported to farmland, and
And traditional desalination technology will also result in environmental pollution, therefore these are not the hair of most direct most effective Marine agriculture
Exhibition approach.
In conclusion needing to solve two large problems for Development of Marine agriculture project: fresh water and plantation substratess.If energy
It combines both, will be a completely new idea.In view of the above problems, the present invention proposes that one kind can directly be irrigated with seawater
The technical solution of the self-produced fresh water planting unit of solar energy.
Summary of the invention
The present invention provides the self-produced fresh water planting units of solar energy that one kind can directly be irrigated with seawater.The device can benefit
