Description
Technical Field
The invention relates to a seawater desalination platform, in particular to a landscape seawater desalination platform for leisure/rescue.
Background
Nowadays, with the improvement of the quality of life and requirements of people, offshore sightseeing leisure and recreation sports become active day by day, and offshore rescue is also important day by day, but at present, closed cruise ships and yachts are generally adopted in people's offshore sightseeing leisure and recreation sports and rescue, and daily water sources are almost all supplied by land fresh water, so far, no movable landscape offshore leisure/rescue platform is available, and no research and practice report of a landscape seawater desalination platform for leisure/rescue is available.
On the other hand, the per capita water resource amount of China is only 2200 cubic meters, which is only 1/4 on the average level in the world, and is one of the countries with the most scarce per capita fresh water resource in the world, and the fresh water resource of China is extremely unbalanced in spatial distribution, so that an obvious pattern of less east-docetaxel, less south-north, more summer-winter is formed, and the pattern is more obvious in north China, northeast, northwest and coastal areas. The coastal region is the region with the most prosperous economy, the most dense population and the most developed maritime leisure and entertainment in China, but the water shortage phenomenon in the region is increasingly serious along with the increase of population including the surge of tourism population, water source pollution, industrial and agricultural development and the increase of water for ecological environment, so that the rapid development of the economy in the coastal region is severely restricted, and the daily work and life of residents are also seriously influenced.
The development of the seawater desalination industry, which supplies fresh water to inexhaustible sea, is a powerful supplement to coastal region water resources, is an effective measure for increasing fresh water resources, and is an effective way for sustainable utilization of water resources. At present, 142 seawater desalination projects are built in China, and the daily average produced water is more than 120 million tons. The north is mainly large-scale industrial seawater desalination engineering, mainly focuses on high-water-consumption industries such as electric power, steel and the like in Tianjin, Shandong, Hebei and the like, and the south is mainly civil seawater desalination engineering which is mainly distributed in Zhejiang, Fujian, Hainan and the like and mainly takes hundred-ton-grade and thousand-ton-grade engineering.
As is known, most of the salt dissolved in seawater exists in the form of ions, which mainly include cations such as Na +, K +, Ca2+, Mg2+, Sr2+ and anions such as Cl-, SO42-, Br-, HCO 3-and F-, and the salinity of typical seawater is generally between 30 per thousand and 43 per thousand. Currently, the main modes of seawater desalination can be broadly divided into two main categories: firstly, water is directly taken out from seawater, salt is remained in the residual strong brine, and the adopted technical methods mainly comprise a distillation method, a reverse osmosis method, a freezing method, a hydrate method and a solvent extraction method. Secondly, salt is taken out from the seawater, so that the salinity of the seawater is greatly reduced to fresh water, and the adopted technical methods mainly comprise an ion exchange method, an electrodialysis method and a capacitance adsorption method. The existing various seawater desalination methods/techniques can be summarized as follows;
1. method for extracting water from seawater
1.1 distillation method
(1) Multistage flash (MSF)
The heated seawater is evaporated in a plurality of flash chambers with gradually reduced pressure in sequence, and the evaporated steam is used for heating the circulating seawater and condensing the seawater into fresh water. The device has large single machine capacity and good effluent quality, but has high construction and equipment investment, large volume, high energy consumption, higher requirement on seawater pretreatment, smaller operation elasticity of the device, high corrosion speed, and possibility of polluting finished water if leakage occurs, and is generally used for thermal power plants with available waste heat and the like. Meanwhile, the thermal distillation causes thermal pollution to the marine environment, and corrosion products of the thermal distillation have toxic action to the sea.
(2) Low temperature multiple effect distillation (LT-MED)
The heated seawater is serially operated by a plurality of evaporators, and the secondary steam evaporated in the previous effect is used as the heating steam of the next effect and is condensed into fresh water. The system has good effluent quality and large system operation elasticity, but has large equipment volume, higher equipment investment, higher requirements on corrosion and scaling, higher requirements on seawater pretreatment and high operation cost, is generally only used in places with waste heat or other heat sources, such as large-scale thermal power plants and the like, and adopts thermal distillation to cause thermal pollution to the marine environment, influence parameters such as seawater level, dissolved oxygen content and the like, and indirectly generate adverse effects on marine organisms and water quality.
(3) Vapor compression distillation (VC)
The steam generated by the heated seawater is pressurized again, the temperature of the steam is increased, and then the steam is used as the heating steam of the evaporator and condensed into fresh water. The device has the advantages of relatively compact structure and higher energy utilization rate, but the device has large volume, high requirement on the sealing property of the system, easy scaling, higher requirement on the pretreatment of seawater and high operation cost, and also has high thermal pollution to the marine environment when being used as a thermal method for treating seawater.
1.2 reverse osmosis (SWRO)
A method for desalinating fresh water by applying pressure to seawater to make the fresh water permeate through a reverse osmosis membrane. The device gets rid of the dependence on waste heat, does not need to consume steam, has large volume and is easy to automatically control, but has strict requirement on seawater pretreatment, and increases the operation cost and the occupied area; the strong brine has high energy carrying away, and the energy utilization rate is low; the operation is unstable, and the water yield is reduced and the water quality is unstable due to easy scaling; the semipermeable membrane needs to be cleaned and replaced regularly, so that the operation cost and the pollution of the chemical cleaning agent to the ocean are increased; the fresh water treatment cost is high.
1.3 freezing method
The freezing method comprises three types, namely a natural freezing method, an artificial freezing method and an exchange crystallization freezing desalting method. The natural freezing method is to freeze sea water and freeze the sea water to ice by using natural environment conditions, and the ice is melted to prepare fresh water, and the method is greatly influenced by natural environment factors such as seasons and the like. The artificial freezing method is to utilize direct or indirect heat exchange between a refrigerant or a refrigerant (n-butane, isobutane, R410A and the like) and seawater to freeze and freeze the seawater, but the artificial freezing method has the problems of larger equipment, high energy consumption in the process of recovering and reusing the refrigerant, high energy consumption in the process of melting ice, low desalting rate and the like. The exchange crystallization freezing desalination method is a heat exchange crystallization method which utilizes precooled seawater and straight-chain hydrocarbon coexisting in a solid-liquid state, and the energy consumption is high due to pressure conversion in the separation process.
1.4 hydrate method
The hydration crystal is formed by hydration agent (monofluoro dichloroethane, methane, carbon dioxide gas, etc.) and water under certain temperature and pressure, the crystal particle is easy to form compression agglomeration and is difficult to clean, and the fresh water is mixed with trace hydration agent, so the quality of the fresh water is relatively low.
1.5 solvent extraction
Extracting with an extractant (such as mixed extractant of methyl diethylamine and triethylamine) to obtain water, and separating solvent with water to obtain fresh water. The method is a liquid-liquid conversion process, and the latent heat of phase change is very small, so that the energy consumption in the process is not large, the corrosion of materials is light, and the scaling problem is not obvious. However, the selection of the extractant, the quality of the fresh water and other technical problems still exist, so the method is in the experimental research stage so far.
2. Method for removing salt from seawater
2.1 ion exchange method
The cation exchanger is used for adsorbing cations in water and releasing hydrogen ions, the anion exchanger is used for adsorbing anions in water and releasing hydroxyl ions, and the anions and the hydroxide ions are neutralized to achieve the purpose of desalting.
2.2 Electrodialysis (ED)
The process of producing fresh water by utilizing the selective permeability of the anion exchange membrane and the cation exchange membrane to the anions and the cations in the seawater and causing the salt and the moisture in the seawater to respectively move directionally under the action of the potential difference generated by the electric field. Compared with reverse osmosis, the method has the advantages of simple pretreatment on seawater, high raw water recovery rate, poor product water quality, high energy consumption and incapability of effectively removing organic matters and bacteria.
2.3 capacitive adsorption method
The method separates ions in seawater by electric double layer discharge to obtain fresh water. The method also deals with experimental research stage, and is not applied industrially.
3. Combined sea water desalination method
3.1, combination with renewable energy sources, the prior art mainly comprises:
(1) solar seawater desalination: the heat generated by solar energy is used for replacing heat sources such as steam and the like to heat and distill the seawater to dilute, the method has large loss of the latent heat of steam condensation, and simultaneously, the problems of scaling inside materials, long-term stable operation of photo-thermal materials, efficient condensation and recovery of water vapor and the like are not considered.
(2) Desalting seawater by using geothermal energy: the method mainly utilizes geothermal resources (waste oil and gas wells) and the like to convert into mechanical energy to pressurize seawater to overcome natural permeation for desalination, needs to be combined with a reverse osmosis method and a low-temperature multi-effect distillation method for application, and can generate new secondary pollution in the utilization process of the waste oil and gas wells.
(3) Wind energy/ocean energy sea water desalination: the seawater desalination method mainly utilizes mechanical energy generated by wind power or mechanical energy converted by tidal energy, wave energy, temperature difference energy and the like in the ocean to pressurize the seawater so as to overcome natural permeation to dilute the seawater, and needs to be combined with a mainstream seawater desalination method for application.
3.2 methods themselves or combinations between methods
Combinations of the processes themselves, such as multistage, reverse osmosis or electrodialysis; the combination of the methods such as the combination of multi-stage flash evaporation and multi-effect evaporation, the combination of nanofiltration, reverse osmosis and multi-stage flash evaporation and the like can improve the recovery rate or the utilization rate of heat and electricity and reduce the cost, but the defects or the shortcomings of the methods cannot be overcome.
Obviously, the existing seawater desalination technologies have the technical problems of high construction cost, large equipment floor area, high requirement on seawater pretreatment, complex process, high energy consumption, high water production cost, low fresh water separation efficiency, low fresh water effluent quality, influence on marine ecological environment and the like.
In addition, the high-frequency oscillation of the fluid is excited by using the oscillation source to generate various ultrasonic effects, such as mechanical effect to destroy the acting force among liquid molecules, thermal effect to enable the molecules to vibrate violently and rub violently to generate heat, cavitation effect to enable a large amount of small bubbles to be generated in the liquid and to expand and burst rapidly, and thixotropic effect to cause the change of the biological tissue combination state, so that the liquid is atomized or bacteria are killed rapidly, but the ultrasonic oscillation method and other methods are mainly used for pretreatment such as scaling prevention and seawater sterilization in the aspect of seawater desalination, and no report in the aspect of research or practice of efficiently desalinating seawater by using oscillation phased array resonance is seen.
Furthermore, for the research of directly utilizing the offshore platform to desalt the seawater, the current technical scheme is limited to the seawater desalination technology utilizing the offshore solar energy, and CN 201610162547.7 provides a solar seawater desalination overwater platform for heating and distilling the seawater by solar energy. It has obvious disadvantages: firstly, the heat generated by the solar heat collecting plate only acts on the surface of seawater, the heat exchange effect is poor, and the efficiency of steam generation is low; secondly, sea wind can only blow through the main shell to cool, the actual cooling effect is very poor, and the water production efficiency is extremely low; thirdly, the pressure is increased by increasing the density of seawater, the sealing sheet is opened for draining, the density of the seawater is very high, the fresh water content is reduced, and the water inlet is intermittent, so that the evaporation efficiency of the seawater is lower, and the water making efficiency is lower; fourthly, the wind wave resistance/the survival ability of the platform are extremely poor, and the platform cannot move autonomously and only can be dragged by a ship to avoid wind waves; fifthly, the function setting of the solar seawater desalination device can be only used for solar desalination of seawater; and sixthly, the buoyancy is provided only by air remained in the main shell, so that the marine floating cage is extremely easy to sink in a complex marine environment.
To date, no research and practice report is available on landscape seawater desalination platforms for leisure/rescue.
