Abstract
The present invention relates to a marine sea water desalination auxiliary method utilizing natural energy sources. Under the condition that energy sources provided by humans are not consumed, fresh water is effectively prepared by the energy sources (high-strength solar heat energy and the condensation of low-temperature sea water flowing relative to a ship body due to the traveling of the ship body) of the natural environment in the specified season (namely the summer that the quantity of the consumed fresh water is greatly increased), and the present can ease the tight fresh water of ships in summer in the eupelagic process. In order to reach the purpose of the utilization of natural energy sources, in the structure, a sea water evaporator is arranged on the upper part of a deck of the ship body or/and the top part of a building, a steam condenser is arranged on the bottom part of the ship body, and the sea water evaporator is connected with the steam condenser directly by a gas conveying pipeline. If necessary, a sea water cooling system of an airscrew engine can be taken as an advanced sea water preheating device of the sea water evaporator, and waste heat generated by the engine can be reutilized.
Description
Technical field
The present invention relates to especially wherein fully and efficiently utilize natural energy resources, i.e. the technology of " cold energy " of seawater liquefaction fresh water for auxiliary energy-conservation " sea water desalination " technology of other " main body " (for example: passenger steamer or warship) adapted.
Background technology
At present, in maritime activity (comprising civil and military), the fresh water that consumes in the ship of oceangoing voyage mainly is by the mode of carrying out from the land or/and directly adopt the mode (needing to consume the people for the several different methods of the energy is provided) of conventional sea water desalination to obtain.
Summary of the invention
The present invention's purpose: the sea water desalting auxiliary method that proposes to utilize natural energy resources (especially " cold energy " of seawater).
In order to realize goal of the invention, the technology of intending employing is as follows:
Its device structurally comprises: salt water evaporator and water vapor condensation device, salt water evaporator wherein are arranged on sunlight is not blocked on the hull top, deck or/and the position of top of building.---utilize solar power to be vaporized into aqueous vapor, utilize low temperature seawater to liquefy on the spot by the aqueous vapor in the water vapor condensation device by the seawater in the salt water evaporator;
It is characterized in that:
Water vapor condensation device as the source of the gas accepter who directly carries by gas transmission pipeline by the water vapour that produces in the salt water evaporator, be to be positioned at the low temperature seawater direct contact and to carry out the bottom of the hull of interchange of heat, and the static state low temperature seawater that allows relative flow when hull is advanced is realized continuous liquefaction fresh water process to the aqueous vapor in the water vapor condensation device.---the present invention also can be with the salt water cooling system of the airscrew engine front device as salt water evaporator, and the waste thermal energy that produces when utilizing airscrew engine work carries out preheating to seawater.
Characteristics of the present invention: need not to consume the people for the major premise that the energy is provided under, the energy (mainly being " cold energy " that makes full use of in the hull bottom flowing seawater) that makes full use of in the natural environment is produced fresh water in short supply in the sea-freight process.
Description of drawings
Figure has illustrated structural principle of the present invention.
1: hull; 2: be laid on the boat deck or/and the solar energy sea water evaporator of top of building; 3: gas transmission pipeline; 4: be positioned at and with the low temperature seawater direct contact and carry out the water vapor condensation device of the boat bottom of interchange of heat.
The specific embodiment
Evaporation of seawater or the rapid evaporation utilizing solar power to impel to hold in the salt water evaporator 2 have become well-known general knowledge.---the device that the present invention adopts impels the effect of evaporation of seawater (although not reaching the degree of boiling as yet) splendid too in solar energy heating, seawater will improve gaseous tension in the salt water evaporator 2 after being vaporized into aqueous vapor, and generation compressing aqueous vapor enters the trend in the water vapor condensation device 4 that is positioned at hull bottom by gas transmission pipeline 3.
Be exactly in summer, several meters dark water temperatures in underwater can not be higher than 30 ℃ usually in the ocean, and, because hull 1 is in the process of navigation, the seawater of static hull 1 bottom, water vapor condensation device 4 with respect to being positioned at boat bottom flows,---the normal temperature seawater that flows makes the effect of aqueous vapor liquefaction splendid.After the aqueous vapor that enters sea water condenser 4 was liquefied, the gaseous tension in the water vapor condensation device 4 diminished, and produced the trend that attracts aqueous vapor to enter sea water condenser 4 automatically.
Impel the splendid and mobile normal temperature seawater of effect of evaporation of seawater allow the useful effect of splendid these two aspects of effect of aqueous vapor liquefaction by above-mentioned solar energy heating, seawater in the above-mentioned salt water evaporator 2 can be looked particular case and constantly replenish in right amount, liquefaction fresh water in the above-mentioned water vapor condensation device 4 can be looked particular case and constantly all take out, and realizes the intension of the described content of title of the present invention with this.
Obviously, the present invention especially can make full use of the Nature energy (above-mentioned seawater " cold energy " especially wherein) is produced fresh water expeditiously from seawater season (summer), the season (summer) that also just in time is to use the fresh water amount to increase sharply, this just can for summer the ocean various hulls 1 realize almost need not providing the process that just can implement sea water desalination under the major premise of the artificial energy, have its just right " assisting " realistic meaning.
