Description

Seawater Desalination System {Seawater Desalination System}

The present invention relates to a seawater desalination apparatus, and more particularly, to a seawater desalination apparatus capable of desalination (fresh water) of seawater introduced by tidal tidal waters located in a coastal or co-surface area or a tidal flat or in the ground thereof.

With the development of modern industry, complex urbanization and industrialization, in an increasingly complex world, forests are devastated by the development and investment of real estate.

Concerned about water pollution both on land and at sea, many scientists and inventors in water purification are doing their best in research and development efforts to solve water pollution.

However, unlike fresh water, seawater contains a large amount of salt, so facilities for desalination of seawater are

It was so large, with so many investments and facilities that it was impossible to use it for individuals or families.

In order to obtain fresh water from technically required seawater, the dissolved or suspended components in seawater must be removed. The components in seawater are almost constant except in certain areas.

The components that must be removed from seawater to produce fresh water are mainly ionic components.

Seawater desalination is divided into evaporation and reverse osmosis. Recently, the reverse osmosis method, which is relatively energy efficient, has been widely used. According to the reverse osmosis method, seawater is separated into treated water and concentrated water by separating components contained in seawater using a polymer separation membrane.

Looking at the principle of desalination of seawater using reverse osmosis, when pressure is applied to the seawater over an osmotic pressure, water is purified through the reverse osmosis membrane and ions or molecules are concentrated through the reverse osmosis membrane. It is already known that the higher the salt concentration of seawater to be desalination, the greater the pressure on the feed water.

 In addition to inorganic and ionic components, seawater contains biological organisms including microorganisms. These biological organisms cause many problems in the desalination process of seawater as follows.

Biofilms are formed by attaching biological organisms to various reservoirs, filters, and pipes of the desalination plant, and this phenomenon is called bio-fouling. As the attached biological organisms grow over time, i.e., as the biofouling intensifies, the reservoirs, strainers, and tubing become unable to function.

For example, if the bio fouling phenomenon lasts for a long time, the pipe is clogged by the biofilm formed on the inner wall of the pipe, the biofilm formed in the storage tank reduces the storage capacity of the tank, and the biofilm formed in the filter

Decreases the filtration performance of the filter. In addition, corrosion of the equipment due to the biofilm may occur. Therefore, there are still disadvantages in that large-scale land and real estate are required to convert freshwater into freshwater or freshwater easily in small or poor countries.

In addition, there was a problem in carrying and installation, and the filter or hollow fiber membrane method has a problem in the medium to long term use, which is convenient for the user, and the portable and installation of fresh water or desalination device from seawater, It was required.

In order to provide economically desalination facilities without taking up real estate on land

The invention is a structure that can be minimized in size as a whole, so that it can be used immediately upon installation

Providing medium and long term use and economical and compact seawater desalination device.

The present invention relates to a seawater desalination apparatus,

Specifically, it is installed in coastal areas such as seawater or existing tidal flats, beaches, and near-shore seas, or it is installed in the ground or underwater of the area so that it does not occupy the real estate of the land. Sea water is introduced into a certain level by the inflow of seawater by means of heating, and is heated by a heating part or a heating element that heats the introduced seawater.

Generates water vapor and condenses water vapor in an enclosed interior space, collects water droplets, guides the fresh water down, and detects or detects the amount of fresh water (fresh water) through the water level sensor. It provides a seawater desalination device as a means for supplying fresh water to the outside by operating the water pump according to the signal of the control unit by the power of the wind, tidal power, wave power.

As described above, in the seawater desalination apparatus, the use of energy is reduced by the inflow of seawater by natural forces, thereby reducing the fuel cost and the emission of pollutants, and the carrying and installation are simple, and the overall cost such as the maintenance cost is economically effective. have.

Although the present invention has been described for convenience of the present invention with reference to the accompanying drawings, it is obvious that various modifications and changes can be made within the scope of the technical idea of the present invention.

The seawater desalination apparatus of the present invention will be described in detail with reference to the accompanying drawings.

First, Figure 1 is an external perspective view showing a seawater desalination device (1) of the present invention.

Seawater desalination device (1) is the body 10 and the bottom portion (bottom) of the sea water inlet (7) is located, the fresh water outlet (15) on the outer peripheral surface of the body 10 and the power supply and communication from the outside Waterproof cable 100 is connected to the waterproof so as to provide a means for supplying power from the outside.

FIG. 2 is a side cutaway view of FIG. 1;

3 is a cross-sectional view showing the operation of the check valve of the seawater desalination device of the present invention,

4 is also a cross-sectional view showing the operation of the check valve of the seawater desalination device of the present invention.

Inside the body 10 of the seawater desalination apparatus 1, seawater can be introduced at a predetermined level, and a heating 11 or a heater (or a heater or a heating device) that can store and heat the seawater introduced at a certain level is heated. The fresh water storage unit 13 or the constitution that generates water vapor by means of means or methods, and saturated water vapor in the interior space 5 of the body 10 is condensed, condensed, or cooled to be collected by water droplets to fall down by gravity. Fresh water reservoir or fresh water storage space 13, and the control box 30, which is waterproof and is equipped with an electronic circuit (not shown) and the external fresh water to the water pump (17) through the external discharge pipe (15) It consists of supplying fresh water to the outside.

Therefore, the seawater desalination apparatus 1 of the present invention should be locked to a certain depth of water naturally.

The use or function of the present invention is the same in the scope of the present invention even in the operation, use, or method of use, even if the seawater is introduced into the inside or the seawater is forcibly introduced even though it is not locked in the seawater.

The seawater containing salt first moves (or enters) into the body 10 through an inner tube 3 of the seawater inlet 7 located at the bottom of the body 10 or below (or below) the body 10. )

At this time, the seawater passing through the filter 20 for filtering the suspended substances, etc. is passed through the check valve to enable fluid movement in only one direction.

This configuration is useful for vertical check valves to prevent the inflow of sea water above a certain level.

If this is described in detail, the buoyancy member 21 and one portion for setting a predetermined level are vertically extended to a certain length to support the buoyancy member 21, and the other is possible by means or a method connected to the moving valve 25.

At this time, the upper and lower limit jaw (27) and the lower limit jaw (29) is present in each of the upper and lower portions to have the upper and lower limit movement distance of the moving valve 25, the water level is increased vertically as the seawater flows in the buoyancy member (21) ) Can be used plastic or lighter than seawater, plastic balloons with air inside. The reason for this is to allow only a certain amount of seawater to flow in accordance with the height of the water level, and to provide a check valve role or function to have the flow of seawater in one direction (one direction).

The sea water inlet 7 extends a predetermined length from the outside of the body 10 to the inside of the body 10 in a vertical form as shown in the drawing, and the sea water is introduced into the space inside the pipe to the heater part having the check valve and the heating element 11 in the middle. It extends in the form of a guideable pipe.

Therefore, the external seawater passes through the filter 20 and vertically moves before entering the body 10, and then passes through a check valve and no longer flows from a predetermined level.

And when seawater is introduced at a certain level or a certain height, the introduced seawater is heated to generate steam.

In the heating method, a heater (heating element) 11 or a planar heating element is heated along the outer circumferential surface of the introduced seawater upper side.

At this time, the heating temperature is suitable 30 ~ 90 degrees.

Here, some of the heated seawater is separated from the seawater with water vapor and is located anywhere in the internal space 5 of the body 10 while moving without boiling, and condensing on the cold inner wall of the body 10 to become water droplets or the body. Floating on the space of the internal space (5) of 10, meets the neighboring water molecules or water vapor, and gradually grows in the form of water droplets, falling by gravity, and finally fresh water located below the internal space (5) inside the body (10) It is a structure that is naturally stored in the fresh water storage space 13 to trap.

And the water pump 17 is located in a portion of the body 10 by the water pump 17 is operated by the signal of the control box 30 of the waterproof function is located or installed on one side inside the body (10) Pressurized internal fresh water is characterized in that it can be discharged to the outside through the discharge pipe (15)

It is the seawater desalination apparatus 1 of this invention.

 In the seawater desalination device 1 of the present invention, when seawater exists around the outer circumference,

That is, when submerged (or submerged) in the seawater, the seawater naturally flows into the body 10 by the water pressure, while heating by a heating device or a heating means near the level of the water level to generate water vapor and to cool the steam Has an integral configuration to obtain fresh water;

Therefore, it is used as a submersion in seawater or buried in tidal or sandy beaches.

Does not take real estate

The fresh water generated in this way has a feature that can be sent to the necessary place through the extension hose (200).

As shown in FIG. 3, the seawater present in the vertical pipe or the vertical pipe outside the body 10 is filled to a predetermined height vertically.

In Figure 4 is shown to explain the check valve structure that operates so as not to exceed a certain level or more.

Similar but not the check valve type described or described herein

One-way seawater flow, storage and heating are also included in the constitution or technique of the present invention, in which the heating portion that generates steam is integrally present.

Therefore, it is an invention that can be desalted by external electric power even from the outside, and is compact, easy to carry, carry and install.

5 is a cross-sectional view showing an example of use of the seawater desalination apparatus of the present invention,

6 is a view showing an example of use of another seawater desalination apparatus of the present invention.

As shown in the drawing, Figure 5 is buried or installed in the basement, such as the tidal flat or the shared surface 900, such as the sea water 300 or seawater exists, the ground is completely buried or buried in the seabed underground, even if the installation is not visible from the outside And operation is possible.

The reason is that if a small amount of seawater flows in through sand or mud flats, the function of the present invention is sufficiently exhibited.

In addition, FIG. 6 shows the state of being used by being immersed in seawater.

The cable 200 is connected to receive power from the outside, and the supply hose 200 can supply fresh water to a tree 700 or a plant or living water in a short distance.

The power is supplied from the outside, it is characterized in that it is operable even when a relatively small power supply such as a solar cell, a wind generator or a battery.

The material of the body 10 is most efficient if the metal is a good thermal conductivity.

The reason is that the heat is shifted by the temperature of the sea water or the ground surrounded by the outside to cool the temperature of the water vapor inside the body 10 to help the water droplet formation efficiency.

However, any material can be applied as long as it is in a waterproof or waterproof state such as ceramic, porcelain, plastic, etc. in addition to the metal material.

That is, the seawater desalination apparatus of the present invention is immersed in seawater or on the seabed or undersea

There is a big feature to be buried.

A body having a sealed inner space from the outside and one side of the inner receiving space of the body is accommodated in the waterproof control box to accommodate a control box that can operate the seawater heating and water pump with power supplied from the outside, and the body In the bottom part, the seawater from the outside of the body in the form of a vertical pipe or pipe is guided vertically to the inside of the body in the form of a vertical pipe or pipe with seawater pressure. The internal space inside the body where water vapors such as heaters or heating wires that heat the stored seawater are heated (heated) to a certain temperature to generate water vapor and spread out into the closed body space, and then water vapor is collected to form water droplets. Water droplets fall naturally due to gravity, but store fresh water on the bottom of the inner space inside the body. It has a structure to form or accommodate a storage unit, and is equipped with a water level sensor and a water pump for measuring the fresh water level, the fresh water stored by operating the water pump by the electronic control unit of the control box through the discharge pipe outside the body It is a seawater desalination device of the present invention characterized in that it can be supplied to the outside.
