Description
Technical field
The invention belongs to the technical fields of sea water desalination and purification, provide a kind of desalinate using photothermal conversion function, only
Change the method for seawater.
Background technology
With the fast development of national economy and increasingly sharpening for problem of environmental pollution, water resource is extremely in short supply to be had become
One global common problem.Currently, the whole world is with the presence of the different degrees of water shortage problem of more than 100 a countries.The people in China
Equal water resource occupancy volume is only the 1/4 of world average level, be 13 poorest countries of global water resources ownership per capita it
One.In the world can be by 0.01% of freshwater resources less than total water resource that the mankind directly utilize, and the growth of population, agricultural and work
The development of industry, the fresh water for causing fresh water especially clean are reduced rapidly.There are 300,000,000 populations to need to lean on seawater or salt ground water at present
Reprocessing obtain domestic water, thus sea water desalination has great strategic significance and development prospect.To ensure China's economy
Sustainable development, alleviate contemporary shortage of water resources, greatly develop desalination technology industry to solve the problems, such as freshwater resources
It is extremely urgent.Therefore, develop desalination technology, the task of top priority that fresh water has become modern society is asked for ocean.
Sea water desalination is exactly by the process of salt and water separation in seawater, is by physics, chemically or physically chemical method
It manages in fact.Sea water desalination is broadly divided into the way of distillation（Hot method）With it is reverse osmosis（Embrane method）Two major classes, specific desalination technology are more than
More than 20 plant, including multistage flash distillation, low-temperature multi-effect, reverse osmosis, electrodialysis, pressure steam distillation, tidal energy seawater desalination technology etc..Through
Semicentennial development is crossed, is formd with multistage flash distillation, multi-effect distilling and the reverse osmosis industrial technology for mainstream.And seawater cleaning
It is further to be had with other using microorganisms such as harmful bacterias in either physically or chemically processing seawater on the basis of desalination
Evil substance, to obtain the process of cleaning and heath fresh water.Simplest in the above method is to make moisture evaporation using heating seawater,
Then cooled vapor obtains the way of distillation of fresh water（Evaporation）, other methods exist desalination system complexity, operating process difficulty
Larger and cost drillmaster's great question, heating vaporization are not also influenced because it has by the salt concentration of seawater and organic concentration
Advantage is current main stream approach.
At present both at home and abroad in terms of sea water desalination, purification, especially achieved in terms of desalination by distillation seawater centainly at
Effect.Wherein Zhang Xiaodong et al. has invented a kind of method for desalting seawater（Chinese invention patent application number 201710412080.5）, main
Step is wanted to have sea water preprocessing, ultra-filtration filters, first-stage reverse osmosis filtering, two-pass reverse osmosis filtering, mineralising, but this method technique mistake
Journey is complicated, and input cost is higher, and it is undesirable to desalinate clean-up effect.In addition, Yin Hua has frequently invented a kind of distillation sea water desalting
System and its desalination method（Chinese invention patent application number 201510407041.7）, including duplex matter system and evaporation of seawater
Cooling system, duplex matter system include force (forcing) pump, and force (forcing) pump connects evaporator by injector, and evaporator passes through steam-water heat exchanging
Device connects the force (forcing) pump, and institute's vapor-water heat exchanger connects the injector, forms duplex matter system, evaporation of seawater cooling system
Including sea water pump, sea water pump connects institute's evaporator by heat exchanger, and evaporator connects the vapor-water heat exchanger, vapor-water heat exchanger
Fresh-water tank is connected by heat exchanger, but this method is desalinated because heating, the organic matter in moisture is evaporated together with moisture, is caused
Purification is not thorough, and desalination water is difficult to directly drink.
As it can be seen that the desalting process of the prior art is complicated, desalting plant is inconvenient to carry, while conventional distillation is heated
Journey is extremely inconvenient in operations offshore, and in addition because heating is desalinated, the organic matter in moisture is evaporated together with moisture, causes not having
Effect purification, gained fresh water can not directly be drunk.
