Description
Technical Field
The invention relates to the technical field of sea water desalination, in particular to an equipment system for atomizing cyclone desalinated sea water by utilizing an ultrasonic array and a desalination method thereof.
Background
As is well known, the average salinity of the earth seawater is 35 per mill, the seawater salinity in different areas has a certain difference, the salinity of shallow sea is generally 27 to 30 per mill under the influence of the fresh water on continents, the salinity of estuary areas is generally 0 to 30 per mill, the salinity of bay areas is often higher than 45 per mill due to the higher evaporation capacity, the smaller fresh water runoff and the influence of high-salt wastewater discharged by a seawater desalination plant, and the salinity of the Mediterranean sea and the red sea is also more than 41 per mill.
The seawater has complex salt content mainly comprising Na + ，K + ，Ca 2+ ，Mg 2+ And Sr 2+ Plasma cation and Cl - ，SO 4 2- ，Br - ，HCO 3 - Plasma anions and molecular H 3 BO 3 And the like. The salinity of typical seawater is generally between 30 per mill and 43 per mill, wherein Ca2 + The content variation range is 360-500 Mg/L, mg 2+ The content variation range is 1150-1600 mg/L, na + The content variation range is 9700-13500 mg/L, K + The content variation range is 400-550 mg/L, cl - The content variation range is 16300-23700 mg/L, SO 4 2 The content of HCO is varied within the range of 2400-3380 mg/L 3 - The content variation range is 130-200 mg/L. In other words, sea water is also an infinite salt mine, and a great deal of industrial salt and civil salt in China come from well salt in inland areas, and the great deal of exploitation of well salt causes geological subsidence collapse and waste residue pollution.
In the aspect of sea water desalination, since the 60 s of the last century, a plurality of scientific enterprises and university scientific research institutes related to sea have developed a series of sea water desalination researches and practices, and the current sea water desalination method mainly comprises a distillation method, a membrane separation method, a crystallization method, a renewable energy source combination method, a solvent extraction method, an ion exchange method and the like, and the current research and application results can be summarized into five categories as follows:
the first is a distillation method, mainly comprising:
(1) Low temperature multi-effect distillation technology (LT-MED): fresh water is produced by multiple times of low-temperature distillation and condensation of seawater, but the outer wall of a heat exchange tube is easy to scale, the improvement of the heat efficiency is limited by low temperature (less than or equal to 70 ℃), the equipment volume is overlarge, and the investment is relatively high.
(2) Multistage flash technology (MSF): the seawater is subjected to pretreatment disinfection and vapor heating multistage flash evaporation and then condensed to prepare fresh water, the system has higher operating temperature, high corrosion tendency of structural materials, high heat consumption, high electric energy consumption, high engineering investment, smaller operating elasticity of equipment, and difficult adaptation to engineering with larger fluctuation of water yield, and simultaneously causes thermal pollution to marine environment.
(3) Vapor compression distillation (VC): the steam generated by hot seawater is secondarily pressurized and condensed into fresh water, the system has high requirements on tightness, high requirements on seawater pretreatment, easy scaling, high heat consumption and power consumption, large equipment volume and high running cost, and simultaneously causes thermal pollution to the marine environment.
The second type is a membrane separation method, which mainly comprises:
(1) Reverse osmosis technology (SWRO): the separation of impurities and fresh water is realized by utilizing the pressure difference at two sides of the reverse osmosis membrane, and the current market application accounts for about 85 percent. The method has high requirements on seawater pretreatment, high loss of the membrane component, relatively sensitive membrane flux to temperature, high fresh water treatment cost and high requirements on a large amount of high-quality corrosion-resistant auxiliary materials (stainless steel pipelines, plates and titanium pipelines).
(2) Electrodialysis technique (ED): the potential difference is utilized to directionally move and separate the salt and the water, the operation energy consumption is higher (generally between 17 and 20 kW.h/m) 3 ) And it is difficult to remove the salt with small dissociation degree, the non-dissociative substances, bacteria, etc., and the product water quality is poor.
The third category is crystallization methods, comprising:
(1) Freezing crystallization method
The freezing crystallization method comprises three methods of natural freezing method, artificial freezing method and exchange crystallization freezing desalination method. The natural freezing method is to freeze and freeze sea water under natural environment condition, and to melt the sea water to produce fresh water. The artificial freezing method is to freeze and freeze the seawater by utilizing direct or indirect heat exchange between the refrigerant (such as LNG, n-butane, isobutane and the like) and the seawater, but the method has the problems of large equipment, high energy consumption in the process of recovering and reutilizing the refrigerant, high energy consumption in the process of melting ice, low salt removal rate and the like. The exchange crystallization freeze desalination method is to utilize the heat exchange crystallization of straight-chain hydrocarbon with the coexistence of pre-cooling sea water and solid-liquid state, and the energy consumption is high due to pressure transformation in the separation process.
(2) Hydrate crystallization method: the hydration agent is used to form hydration crystal with water under certain temperature and pressure, and the molecule of the hydration agent is usually composed of methane, ethane, carbon dioxide, nitrogen gas or liquid such as monofluorodichloroethane. The method has the advantages that the crystal particles are easy to form compressive caking and difficult to clean, trace hydrating agent is mixed in fresh water, and the quality of the fresh water is relatively low.
The fourth category is renewable energy combination methods, and the prior art is:
(1) Solar sea water desalination: the method has the advantages that heat generated by solar energy is used for replacing heat sources such as steam to carry out heating distillation for diluting seawater, the method has great steam condensation latent heat loss, and meanwhile, 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) Geothermal energy sea water desalination: the method mainly utilizes geothermal resources (waste oil gas wells) and the like to convert the geothermal resources (waste oil gas wells) into mechanical energy to pressurize the seawater to overcome natural permeation for dilution, the seawater needs to be applied in combination with a reverse osmosis method and a low-temperature multi-effect distillation method, and new secondary pollution can be generated in the utilization process of the waste oil gas wells.
(3) Wind energy/ocean energy sea water desalination: the sea water is pressurized by the mechanical energy generated by wind power or the mechanical energy converted from tidal energy, wave energy, temperature difference energy and the like in the sea to overcome natural permeation for dilution, and the sea water desalination method is combined with the mainstream sea water desalination method.
The fifth type is oil-fat separation and desalination method, such as mixing coconut oil and seawater, heating, condensing, separating and desalting, but the efficiency is low, and secondary pollution is easy to cause. And secondly, various medicaments are added into the strong brine generated in the existing sea water desalting engineering in the desalting process, no corresponding comprehensive utilization treatment measures exist in the follow-up process, and the strong brine is directly discharged into the sea, so that the ecological environment of the sea is greatly influenced.
Obviously, the existing sea water desalination technology has the technical problems of high engineering cost, large equipment occupation area, higher sea water pretreatment requirement, complex technology, high energy consumption, high water production cost, low fresh water separation efficiency, low fresh water outlet quality and the like.
On the other hand, the application of ultrasonic technology in medical treatment, cleaning, mixing and chemical industry is becoming wider, in the aspect of ultrasonic sea water desalination, CN101838079B ultrasonic atomization vaporization sea water desalination and desalination device and method, an ultrasonic atomization vaporization sea water desalination and desalination device is disclosed, sea water is atomized by an ultrasonic atomizer and then sprayed into a gasification furnace through a nozzle, water mist is heated to be gasified and desalted, and fresh water is obtained after condensation; in the solar sea water desalting equipment based on ultrasonic wave and throttling technology, CN101863527A discloses solar sea water desalting equipment based on ultrasonic wave and throttling technology, which can improve throttling efficiency, sea water is flashed to obtain steam, the sea water which is not flashed is further atomized by utilizing an ultrasonic wave vibration generator, sea water evaporation is promoted, and fresh water is obtained after cooling. The desalination and desalination modes of the technologies are basically traditional evaporation method desalination and desalination, ultrasonic waves are only used as auxiliary measures for gasifying and atomizing seawater, the treatment scale of the methods is limited, a stable heat source is needed, and the energy consumption is high.
