Description
Technical field
The present invention relates to field of seawater desalination, and in particular to a kind of seawater desalination system based on vortex tube refrigeration.
Background technique
Water is lifespring and cradle, is the essential base substance of mankind's existence, life and production, is
The control of an important factor for what can not be replaced on the earth obtains valuable basic natural resources, is composition geological environment and ecological environment
One of element, while being also important the Organic structure of strategic resource and a national overall national strength.The scarcity of water resource is
Gradually influence global economy and ecological environment.Relevant bodies of the United Nations once pointed out that " freshwater resources are in short supply will seriously to restrict 21 century
Economy and society development, and it is possible to cause to break out war between country ".
Desalination technology is exactly the salinity removed in seawater and the fresh water for obtaining directly drinking in brief, tradition
Desalination technology include multistage flash distillation (MSF), its advantage is that technical maturity equipment is simple and reliable to be conducive to enlargement, still
Construction investment height is also important restriction factor.Multi-effect flashing steam (MEd) technology reduces life its advantage is that low-grade heat source can be utilized
Cost is produced, but evaporating temperature constrains the thermal efficiency.Reverse osmosis (RO) technology, its advantage is that low energy consumption, the construction period is short, still
It is very stringent to the pre-processing requirements of seawater.
Hydrate is a kind of desalination technology that comparison is environmentally friendly.With low energy consumption, equipment is simple, hydrating agents price is low
Many advantages, such as honest and clean, from a wealth of sources.Hydrate sea water desalination is using the hydrone in hydrating agents gas molecule and seawater one
Hydrate slurry is generated under fixed condition, endothermic decomposition in decomposition of hydrate device is extracted by circulating pump, the liquid water that decomposites is in cooling
In device be heated flash to vapor, vapor in driven fresh water condenser heat release cooling finally obtain fresh water.Hydrate seawater is light
The great advantage of change is that low energy consumption, equipment is simple, maintenance operating cost is low；Solubility of the hydrating agents gas in water or salt water
It is low, nontoxic, cheap and easy to get, no explosion danger.In addition, it also has the advantages that some of freezing do not need such as to carry out in advance seawater
Processing, corrosion are lighter etc..
Hydrate has the feature that (1) hydrate generates and decomposable process is completely reciprocal, generates the raw material of hydrate
Only gas and water, the resultant product after decomposition also only have gas and water, and there are no pollution to the environment, and water is big in nature
Amount is deposited big and cheap；(2) gas hydrate synthesis and the temperature, pressure condition of decomposition are relatively mild.Hydrate slurry is under normal pressure
A kind of solid-liquid two-phase suspension of similar ice slurry, is made of some tiny microgranular Study of Clathrate Hydrates and aqueous solution, 5~
There is very high heat density in 12 DEG C of temperature ranges, can be generated under normal pressure and low pressure operating condition.
The patent of invention of Patent No. 200910214077.8 disclose it is a kind of utilize liquified natural gas (LNG) cold energy carry out
The system of sea water desalination includes that urban water supply system, cities and towns air supply system, LNG handling and stocking system, hydrate seawater are light
Change system and seawater extraction system.The sea water service system is high to LNG cold energy use rate, and high financial profit, cost of investment is small, right
The influence of environment.But its disadvantage is also apparent, i.e., sea water desalination depends on LNG cold energy, therefore the seawater desalination system can only be built
Around LNG receiving station, the popularization and application of the seawater desalination system are limited.
In addition, disclosing a kind of method of sea water desalination, the party in the patent of invention of Patent No. 201110134047.3
Method needs cool down seawater before hydration reaction, increase its degree of supercooling, thus need additional configuration cooling water system, increase
The complexity of equipment, increases the energy consumption of system.
