Abstract
The invention provides a method of desalting seawater, which relates to a method of producing freshwater, and is a method of desalting seawater after comprehensively utilizing natural resources such as wind power, solar energy and seawater, etc. The invention is characterized in that the energy sources are a wind power station and a solar heating device; seawater is pumped to the solar heating device for heating and evaporation, and then the vapor is obtained and is induced to the seabed by use of a vacuum pump, and the evaporation speed of the vapor is accelerated; once meeting the low-temperature environment of seawater at the seabed, the vapor is cooled and condensed, and obtained freshwater enters into a freshwater storeroom through a pipeline for storing. The invention takes full advantages of the natural resources, saves the industrial energy source and protects the environment from pollution.
Description
Technical field:
The present invention relates to a kind of method of making fresh water.Particularly a kind of method with sea water desaltination.
Background technology:
At present, for a lot of to the method for comprehensive utilization of wind-force and seawater natural resources.But the electric energy that wind-force sends is connected to the grid, needs higher technology, cost is higher.
It is very ripe that the water technology is made in sea water desaltination in the seawater comprehensive utilization, but power consumption is big, uneconomical economically, can only use on boats and ships at present.
At present, use the solar heating technology very general, using widely as solar water heater.
But these natural resourcess can not carry out comprehensive utilization.
The present invention aims to provide a kind of method with the coastal waters sea water desaltination.It is a kind of natural resourcess such as wind-force, sun power, seawater that utilize, after the comprehensive utilization with the method for sea water desaltination.
Its method is:
With wind power station and solar heat collector is the energy, seawater is extracted in the solar heat collector with pump heats, evaporation obtains water vapour, with vacuum pump this water vapor is introduced the seabed, and the velocity of evaporation of acceleration water vapor, water vapor runs into the low temperature environment of seawater in the seabed, cools off and condensation, resulting fresh water can enter fresh water reservoir by pipeline and store, as shown in Figure 1.
Enforcement of the present invention can be provided with wind power station, solar heat collector by the sea; Be provided with the seabed fresh water reservoir in the seabed; Wherein, wind power station and vacuum pump, water pump connect with circuit respectively; Sun power is made hot-water heating system and is connected with the seabed fresh water reservoir with pipeline with pump, and with water pump and pipeline be connected with seawater; The output channel of seabed fresh water reservoir is connected with the land fresh water reservoir by water pump.The output channel of seabed fresh water reservoir also can be connected with the land fresh water reservoir by water pump with after solar heater is connected.
The utility model in use, the electric energy that the wind power station relies on wind-force to send is the energy source of this device, it can make vacuum pump and pump operation.
When with pump working that seawater is connected, seawater is made hot-water heating system by extracting to sun power; The running of vacuum pump makes sun power make to be in vacuum state in the hot-water heating system, under vacuum state, the heating of sun power makes seawater increase steam output, water vapor after the evaporation enters the seabed fresh water reservoir by air pump and pipeline, the seabed fresh water reservoir is in the seabed, according to detecting the submarine temperature generally at 20 ℃, therefore, water vapor is condensed into fresh water and stores.
The output channel of seabed fresh water reservoir can directly be connected with the land fresh water reservoir by water pump, stores the fresh water of lesser temps in the fresh water reservoir of land.When the output channel of seabed fresh water reservoir is connected with the land fresh water reservoir by solar heater, in the fresh water reservoir of land, store the fresh water of comparatively high temps.Water uses in can be used as after this fresh water stores in the fresh water reservoir of land.
This device makes full use of the natural resources, and has saved industrial energy, and the protection environment is not contaminated.
In sum, the present invention is a kind of method with sea water desaltination.It is a kind of natural resourcess such as wind-force, sun power, seawater that utilize, after the comprehensive utilization with the method for sea water desaltination.
Embodiment:
When 1 work of wind power station, pump 4 just can start.
The running of pump 4 is squeezed into seawater in the solar heat collector 2 and is heated, and behind the evaporation of seawater, after water vapor entered seabed fresh water reservoir 3 by pump 4, condensation became fresh water.
In spring and summer, about 20 ℃ fresh water can be stored in the seabed fresh water reservoir 3, directly send into the room through the land fresh water reservoir, as the low-temperature receiver of room air conditioner, behind room temperature lowering, water used during the fresh water of elevated temperature can be used as.
In the winter time, can with fresh water from seabed fresh water reservoir 5, enter solar heater 9 heat temperature raisings to about 30 ℃ fresh water, in the land fresh water reservoir is made a gift to someone the room, as the thermal source of room air conditioner, through the circulation heat radiation, make that water uses in the fresh water conduct after the reduction temperature after the room heating.
