Description

Freshwater Production Equipment using Wind Turbine {FRESH WATER PRODUCING APPARATUS WITH WIND TURBINE}

The present invention relates to a freshwater production apparatus using a wind turbine, and more particularly, using a wind turbine to produce food and beverage for human survival using renewable solar energy and wind energy so that no separate finite resources are consumed. A fresh water production apparatus.

Although water shortages have recently emerged around the world, these water shortages are expected to become more severe. In order to solve this problem of water shortage, there are dam construction and groundwater development.However, dam construction is not easy due to the enormous cost as well as damage to the natural environment. In addition to the depletion of water resources and serious contamination of groundwater, it is not easy to secure water resources, which is not a fundamental solution in the long run.

In order to solve these problems, the United States, Japan, Germany, etc. have already developed methods for obtaining fresh water from seawater for a long time and use them as drinking water or industrial water. In general, the seawater contains about 2.7% by weight of sodium chloride as a main component, about 3,800ppm of magnesium chloride, about 1,700ppm of magnesium sulfate, about 1,300ppm of calcium sulfate, and about 900ppm of potassium sulfate.

In order to obtain fresh water by treating such seawater, the Republic of Korea Patent Publication No. 10-227327 (published on Nov. 1, 1999) can purify seawater without adding a flocculant and the like, and improve the utilization efficiency of ozone. Techniques for processing methods and devices are disclosed. The method proposed here is a method of increasing the utilization efficiency of ozone by applying magnetic force to seawater, injecting ozone, and then passing the catalyst layer made of activated carbon to remove the aggregates again by filtration. 1 and 2 are views for explaining an ozone mixer (self-treatment reactor) for a method of obtaining fresh water using the sea water proposed here.

Referring to FIG. 1, the ozone mixer 500 for ozone and magnetically treating seawater is a magnetic treatment part 510 and an ozone injection part 530 which are disposed on a tubular body 512 and 532 such as a PVC pipe. Is done. In this case, the magnetic processing unit 510 is provided with a box-shaped box body 520 which is disposed to be spaced apart from the inner wall of the cylindrical body 512 at a predetermined interval. The rod-shaped box body 520 is configured by arranging several small permanent magnets so that the N pole and the S pole face each other.

2, the ozone injection unit 530 is inserted into the L-shaped ozone injection pipe 540 extending from the ozone generator outside the cylindrical body 532, the wing body around the ozone injection pipe 540 550 is provided, and a plurality of protrusions 560 are installed downstream from the wing 550. Here, the wing body 550 is inclined at 30 to 45 degrees with respect to the flow direction of the water to be treated, and consists of a pair of wing plates 552 and 554 twisted in opposite directions. And the plurality of protrusions 560 is composed of a cylindrical portion 562 fixed to the inner wall surface of the cylindrical body 532 and the mushroom-shaped portion 564 formed at the tip of the cylindrical portion 562 cylindrical body 532 It is arrange | positioned at the inner side wall surface of the crater shape.

The desalination method of the seawater using the ozone mixer 500 is such that the magnetic force acts on the seawater flowing along the circular tube in the magnetic treatment unit 510, and the ozone injector 530 mixes and decomposes the ozone in the filter. To remove fresh water from the aggregates.

However, such desalination method and apparatus is not suitable for the facility to obtain fresh water by treating the sea in large quantities. That is, such a conventional device has a problem in that a number of ozone mixers 500 must be used for the residence time of sea water, so that a fresh water facility may be constructed in duplicate, and the wing body 550 and the stones in the ozone injection unit 530. Since the composition of the gas 560 alone does not achieve effective mixing of ozone, and thus its efficiency is low, there is a problem in that magnetic treatment, ozone, and filtration treatment must be performed twice. Also. The desalination method of the seawater by the apparatus is to treat the seawater in the order of flocculation → oxidation and decomposition → filtration, resulting in a problem that the treatment efficiency of fresh water is low as a result of the decomposition of the aggregate.

Accordingly, an object of the present invention is to produce fresh water by condensing water vapor, which naturally evaporates by solar heat, from the sea surface of the offshore using the wing surface of a wind turbine that is rotated by marine wind, and uses wind energy produced by wind. By providing a fresh water production apparatus using a wind turbine for transporting the fresh water to the land.

In order to achieve the object of the present invention described above, in one embodiment of the present invention is installed on the sea surface of the water offshore, the impeller is rotated by the ocean wind, the water vapor naturally evaporated by solar heat using the surface of the impeller It provides a fresh water production apparatus using a wind turbine including a wind turbine to produce fresh water by condensation.

The fresh water production apparatus according to the present invention uses wind energy as a power source, and since evaporation of sea water uses solar energy, it does not use a separate finite energy for driving. Thus, the present invention uses renewable energy that can be used in large quantities over a long period of time without harming the environment and the human body, thereby producing fresh water while protecting nature.

In addition, the present invention can continuously produce a large amount of fresh water using sea water, it is possible to solve the problem of water shortage.

1 and 2 are views for explaining a conventional ozone mixer.
