Seawater Desalination System {DESALINATION APPARATUS OF SEA WATER}

The present invention relates to a desalination apparatus of seawater, and more particularly, to an economical and efficient desalination apparatus of the seawater by using solar energy to solve the energy required for desalination while reducing costs associated with installation and maintenance.

Water is the most important natural resource for humans, covering about 75% of the earth's surface. About 97% of the earth's water is at sea, and about two-thirds of the remaining 3% are polar ice caps or glaciers.

However, seawater, which exists as sea or polar ice caps and glaciers, is too salty for human or industrial water use, and in fact, there is very little fresh water available for human life.

Moreover, the amount of freshwater available to human life is gradually decreasing due to the increasing industrialization and consequent environmental pollution, which is increasing the shortage and depletion of freshwater.

Therefore, as a solution for the depletion and depletion of fresh water, as described above, a method for converting a large amount of seawater into freshwater is being sought, and various desalination devices for seawater have been developed to implement such a method.

Such seawater desalination apparatus can be roughly classified into a reverse osmosis apparatus, an electrodialysis apparatus, and a distillation apparatus.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, the well-known functions or constructions are not described in order to simplify the gist of the present invention.

First, referring to Figures 1 to 5, the overall configuration of an embodiment of the seawater desalination apparatus according to the present invention.

1 is a perspective view illustrating a desalination apparatus of seawater according to one embodiment of the present invention, FIG. 2 is an exploded perspective view illustrating the decomposition of the heater shown in FIG. 1, and FIG. 3 is a portion A of FIG. 2. It is an enlarged perspective view which shows the enlarged view. On the other hand, Figure 4 is a cutaway perspective view showing a portion of the separator shown in Figure 1, Figure 5 is a cutaway perspective view showing a portion of the seawater collection tank shown in FIG.

As shown in Figure 1, one embodiment of the seawater desalination apparatus according to the present invention, the heater 100, the separator 200, the inlet pipe 300, the discharge pipe 400, the capacitor 500, etc. Can be configured.

Heater 100 is a component that heats the seawater to convert seawater into steam and hot water. That is, the heater 100 serves to separate the steam having a low salt content from the seawater by heating the seawater.

The heater 100 may be configured in a variety of ways, the heater 100 included in an embodiment of the desalination apparatus of the seawater according to the present invention to heat the seawater using solar heat, Figures 2 to 3 It may be configured as shown.

That is, the heater 100 may include a reflective lens 110, a flow path tube 120, a support plate 130, and a cover 140.

Here, the reflective lens 110 is a component that reflects the sunlight so that it can be irradiated toward the flow path (120) to be described later (irradiation). In order to play this role, the reflective lens 110 may be formed in a semi-cylindrical shape having a concave curved surface. That is, the reflective lens 110 may be formed such that its upper portion is open and the cross section of the width direction has a semi-circular shape, and the reflective lens 110 formed as described above may have a plurality of focal points along the longitudinal direction of the semi-cylindrical shape. have. In addition, since the lower portion of the reflective lens 110 is concave, there is a possibility that it can be shaken to the left and right, a pedestal 910 for fixing it may be provided, although not shown, the pedestal 910 moves the sun It may be configured to move in consideration of the path.

On the other hand, the flow path pipe 120 is a component formed so that the sea water can flow along the longitudinal direction where the focus of the reflective lens 110 is located, so that the sea water can be heated by the sunlight irradiated by the reflective lens 110 to be. The flow path pipe 120 may be disposed at the focal position of the reflective lens 110 by fixing only both ends of the inlet 122 and the outlet port 124, but is generated while the seawater flows along the flow pipe 120. There is a concern that the vibration may deviate from the focus position of the reflective lens 110.

In order to alleviate such concerns, the support plate 130 is provided on the open upper portion of the reflective lens 110 to install the flow path tube 120 on the bottom surface of the support plate 130 facing the inner circumferential surface of the reflective lens 110. Can be. In this case, the support plate 130 should be formed to be transparent so that sunlight can reach the reflective lens 110, and has a flat shape rather than having a special shape to easily determine the focal position of the reflective lens 110 Would be advantageous.

On the other hand, the cover 140 is a component for covering the reflective lens 110 to prevent foreign matter on the inner circumferential surface of the reflective lens 110, as long as it prevents foreign matter on the inner circumferential surface of the reflective lens 110 There is no restriction on the shape. However, for convenience of manufacturing, as shown in FIG. 1, the cover 140 may be formed in a semi-cylindrical shape so that both sides thereof may be circular, corresponding to the semi-cylindrical reflective lens 110. When the cover 140 is formed in the semi-cylindrical shape as described above, the support plate 130 provided on the reflective lens 110 is also covered to prevent the foreign matter from entering the support plate 130.

As described above, the cover 140 may be transparently formed on the upper side 146 of the cover covering the upper portion of the reflective lens 110 so that sunlight can reach the reflective lens 110. In addition, the side portions of the cover covering both sides of the reflective lens 110, so that the inlet pipe 300 and the discharge pipe 400 to be described later can be connected to the inlet 122 and the outlet 124 of the flow path pipe 120, The first through hole 142 and the second through hole 144 may be provided to face the inlet 122 and the outlet 124 of the flow path pipe 120.

In the heater 100 which can be configured as described above, the inflow pipe 300 and the discharge pipe 400 are connected so that the sea water is introduced and the heated sea water or the sea water is heated to discharge the converted steam and hot water.

In this case, as described below, the inlet pipe 300 and the discharge pipe 400 connected to the heater 100 may be configured to be detachably coupled to the heater 100 so that the heater 100 may be connected to each other.

That is, one side of the inlet pipe 300 for introducing sea water may be detachably coupled to the inlet 122 of the flow path pipe 120 through the first through hole 142. In addition, one side of the discharge pipe 400 for discharging steam and hot water converted by heating seawater or the seawater heated in the flow pipe 120 is formed at the discharge port 124 of the flow pipe 120. Can be detachably coupled through.

In this case, as a detachably coupled method, as shown in FIG. 3, one side of the inlet pipe 300 or the outlet pipe 400 formed as the male screw part is an inlet 122 or the outlet of the flow path pipe 120 formed as the female screw part. A method of screwing to 124 may be used. However, it is natural that such a method is not limited to screwing.

On the other hand, the cross-sectional area of the flow path pipe 120 may be formed wider than the cross-sectional area of the inlet pipe (300). This is to lower the flow rate of sea water flowing into the flow pipe 120 from the inlet pipe (300). That is, the speed of the sea water flowing in the inlet pipe 300 may be fast, but if the speed of the sea water flows in the flow path pipe 120 as fast as the speed of the sea water flow in the inlet pipe 300 is not sufficiently heated by sunlight. This is because the seawater can escape to the discharge pipe 400 without.

The ratio of the difference between the cross-sectional area of the flow path pipe 120 and the cross-sectional area of the inflow pipe 300 may be adjusted in consideration of the amount of light irradiated by the reflective lens 110 and the length of the flow path pipe 120. You can control the rate at which seawater is desalted.

On the other hand, the heater 100 included in an embodiment of the seawater desalination apparatus according to the present invention may further include a solar panel 150.

As described above, the energy of the sunlight irradiated through the reflective lens 110 does not have only thermal energy for heating seawater flowing along the flow path pipe 120. That is, sunlight has not only thermal energy but also optical energy which can be converted into electrical energy.

Therefore, one embodiment of the seawater desalination apparatus according to the present invention does not use the solar light irradiated from the reflective lens 110 as a heat energy source for heating the seawater, but one of the seawater desalination apparatus according to the present invention. It is also used as a light energy source for driving other components of the embodiment, the required component is the solar panel 150.

Since the solar panel 150 is advantageously disposed at the focal position of the reflective lens 110 in view of efficiency, the relation of the flow path 120 already disposed at the focal position of the reflective lens 110 is considered. Should.

In this regard, a method of arranging the flow path 120 and the solar panel 150 together at the focal position of the reflective lens 110 may be variously proposed. However, for a more detailed description, an example will be described in one form shown in FIGS. 2 and 3.

As shown in FIG. 2 and FIG. 3, the flow path tube 120 is formed transparently, and the solar panel 150 may be provided on the top surface opposite to the bottom surface of the support plate 130 on which the flow path tube 120 is installed. Can be.

When the solar panel 150 is configured as described above, the solar panel 150 is not damaged even if sunlight is irradiated to the solar panel 150 for a long time. That is, since the sunlight reflected by the reflective lens 110 is not directly irradiated to the solar panel 150, but is irradiated by filtering the infrared component of the sunlight through the sea water, the solar light to the solar panel 150 for a long time. Even if irradiated, the solar panel 150 is not damaged.

 At this time, the inner cross-section of the flow path pipe 120 is formed in a circular shape in consideration of the frictional force that may be generated during the flow of sea water is separate, the flow path pipe 120 to increase the effect of filtering the infrared components of the solar light as described above ) May be formed into a rectangle having the same width as that of the solar panel 150.

Meanwhile, the electrical energy converted by the solar panel 150 drives the first valve 620 or the second valve 820 respectively provided in the storage container 600 or the seawater collection tank 800, as described below. Can be provided immediately. However, since the first valve 620 or the second valve 820 does not operate until it meets a predetermined condition as described below, the electrical energy converted by the solar panel 150 is a cable extending from the solar panel 150. It is advantageous to store in capacitor 500 via 152.

On the other hand, the rate of heating and the amount of sea water heated in the heater 100, which is the most important control variable for controlling the rate and amount of seawater desalination, the reflective lens 110, the flow pipe 120, the support plate 130, the cover 140, by adjusting the length and width of each component constituting the heater 100, such as the solar panel 150, can be adjusted.

However, adjusting the length and width of each component constituting the heater 100 in this way may have a problem that it may not be possible depending on the location and location where one embodiment of the seawater desalination apparatus according to the present invention is installed. .

Therefore, in order to solve such a problem, a plurality of heaters 100 may be provided, and a method of connecting each heater 100 may be implemented. By the way, rather than simply connecting each heater 100, so that the flow of sea water heated by each heater 100 should be connected so as not to break, the way to connect the heater 100 is the flow path pipe 120 There are two ways to connect the serial and parallel connections.

Specifically, connecting the plurality of heaters 100 in series means connecting the flow path pipes 120 formed in each of the heaters 100 in series. That is, as shown in FIG. 1, the outlet 124 of the flow path pipe 120 provided in the first heater 100a of the plurality of heaters 100 is formed in the flow path pipe 120 provided in the second heater 100b. The outlet 124 of the flow path pipe 120 provided in the second heater 100b may be connected to the inlet 122 of the flow path pipe 120 provided in the third heater 100c.

Here, the first heater (100a), the second heater (100b), the third heater (100c) includes substantially the same components as the heater 100, the heater (most adjacent to the seawater collection tank 800 to be described later ( 100)-the inlet 122 of the flow path pipe 120 of-corresponding to the first heater (100a) in FIG. 1 is connected to the inlet pipe 300, the heater 100 closest to the separator 200 to be described later- In FIG. 1, the outlet 124 of the flow path pipe 120 corresponding to the third heater 100c may be connected to the discharge pipe 400.

When the flow path pipes 120 formed in each of the heaters 100 are connected in series as described above, since the time for heating the sea water becomes long, since the amount of sea water to be returned along the return pipe 700 to be described later is reduced, It will reduce the time it takes to desalination, which will increase the rate of desalination.

On the other hand, connecting the plurality of heaters 100 in parallel means connecting the flow path pipes 120 formed in each of the heaters 100 in parallel. That is, although not shown in the drawings, the inlet 122 of the flow path pipe 120 provided in the first heater of the plurality of heaters 100 is connected to the inlet 122 of the flow path pipe 120 provided in the second heater. The outlet 124 of the passage tube 120 provided in the first heater may be connected to the outlet 124 of the passage tube 120 provided in the second heater.

Here, the first heater and the second heater includes the same components as the heater 100, wherein both the inlet 122 and the inlet pipe 300 of the flow path pipe 120 of the first heater and the second heater It is connected, and both the outlet port 124 of the flow path pipe 120 of the first heater and the second heater and the discharge pipe 400 will be connected.

As such, when the flow path pipes 120 formed in each of the heaters 100 are connected in parallel, the amount of the seawater to be heated increases, so that the amount of desalination of the seawater may be increased.

However, when the heaters 100 are connected in parallel as described above, unlike the case where the heaters 100 are connected in series, the amount of desalination of sea water increases, so that the separator 200 and the storage container 600 will be described later. The size of the back components may also need to be adjusted. However, if there is a great need to increase the amount of seawater desalination, adjusting the size of other components may be easier than adjusting the size of each component constituting the heater 100 as described above.

On the other hand, the separator 200, together with the heater 100 as described above as one component constituting an embodiment of the desalination apparatus of the seawater according to the present invention, the steam and hot water converted by the heater 100 It separates them from each other.

The separator 200 may have any configuration as long as it can separate the steam and hot water converted by the heater 100 from each other. However, for a more detailed description, the separator 200 shown in FIG. 4 will be described as an example.

As shown in FIG. 4, the separator 200 may include a receiving part 210, a first discharge hole 220, a second discharge hole 240, and a blocker 230.

Here, the receiving unit 210 is connected to the discharge pipe 400, a component for temporarily receiving the seawater heated in the steam and hot water or the flow path pipe 120 converted by heating the seawater discharged through the discharge pipe 400 to be. The accommodating part 210 is a kind of housing to which the discharge pipe 400 and the first discharge hole 220 and the second discharge hole 240 to be described later are connected, and a blocker 230 to be described later is provided therein.

On the other hand, the first discharge hole 220 is a component that is open to the lower side of the accommodating portion 210, so that hot water and seawater received in the accommodating portion 210 is discharged by gravity. That is, the first discharge hole 220 is a component for separating the desalted hot water or sea water, and the return pipe 700 to be described later is connected.

On the other hand, the second discharge hole 240 is the upper portion of the receiving portion 210, that is, the second discharge hole 240 so that the steam contained in the accommodating portion 210 is discharged by the vapor pressure of the steam A component that separates steam and is connected to a place of use (not shown).

On the other hand, the blocker 230 is a component provided to block the steam discharged to the second discharge hole 240 is discharged to the first discharge hole (220). The blocker 230 is provided inside the accommodating part 210, and may be configured in the form of a partition wall to prevent steam from mixing again with hot water and unconverted seawater inside the accommodating part 210. That is, since the steam accommodated in the accommodating part 210 is lighter than hot water and unconverted seawater, the steam is located above the accommodating part 210. After the steam is located above the accommodating part 210, the accommodating part 210 is again. As it comes down to the bottom of the) by the blocker 230, the steam is not mixed with hot water and unconverted seawater.

One embodiment of the seawater desalination apparatus according to the present invention can be configured as described above, in addition to the heater 100 and the separator 200, storage container 600, return pipe 700, seawater collection tank 800 It may be configured to include more.

Here, the storage container 600 is provided at one point of the discharge pipe 400 located between the discharge port 124 and the separator 200 of the flow path pipe 120, steam and hot water or heated sea water converted by heating sea water Is a component that is temporarily stored prior to determining whether seawater has been heated enough to be separated in separator 200. That is, the storage container 600 is filled with seawater up to the upper side of the blocker 230 when a large amount of seawater that is only heated without being converted into steam and hot water into the separator 200 flows into the separator 200. Function to remove the risk of not implementing the role of the organization (230).

In order to realize the function of the storage container 600, a temperature sensor 610 may be provided at one side of the storage container 600. That is, by using the temperature sensor 610, by measuring the temperature of the heated sea water or the converted steam and hot water that is temporarily stored in the storage container 600, the heating from the storage container 600 to the separator 200. Decide when to drain the prepared seawater or converted steam and hot water.

As such, when the temperature measured by the temperature sensor 610 is higher than or equal to a preset temperature, that is, when the converted steam is sufficiently high to realize a role of the blocker 230 of the separator 200, the first valve 620 may be used. Is opened, steam and hot water or seawater stored in the storage container 600 flows to the separator 200.

In this case, the first valve 620 may be formed of a solenoid valve (electromagnetic valve) that is interlocked with the temperature sensor 610. The power for driving the first valve 620 formed of the solenoid valve as described above is as described above. Electrical energy stored in the capacitor 500.

On the other hand, when the temperature measured by the temperature sensor 610 is below the predetermined temperature, steam and hot water or seawater stored in the storage container 600 should not flow to the separator 200, the first valve 620 is closed, It flows to the return pipe (700).

Here, the return pipe 700 is a component that flows only the heated sea water from the storage container 600 to the inlet pipe 300 without being converted into steam and hot water. That is, one end is connected to the storage container 600, the other end is connected to the inlet pipe 300, and the seawater heated only when the first valve 620 is not opened in the storage container 600 inlet ( 300).

In addition, the return pipe 700, the first through hole 142 to flow some of the hot water and sea water discharged through the first through hole 142 of the separator 200 back to the inlet pipe 300. Branching from the pipe connected to the use (not shown) in the may be configured to be connected to the inlet pipe (300).

 On the other hand, the seawater collection tank 800 is a component that temporarily stores before introducing the seawater to the inlet 122 of the flow path pipe 120 through the inlet pipe (300). That is, since the amount of seawater recovered to the return pipe 700 as described above is reduced by the amount of steam separated through the separator 200, it is necessary to supplement the amount of seawater introduced through the inlet pipe 300. It is responsible for storing seawater prior to replenishment.

The seawater collection tank 800 may be configured in any structure if it can play a role of temporarily storing the seawater, it is advantageously configured to always be filled automatically so that the inflow of seawater into the inlet pipe 300 does not stop. An example is as shown in FIG. 5.

That is, referring to FIG. 5, an example of the seawater collection tank 800 will be described in detail. The seawater collection tank 800 has a water level sensor 810 for measuring the amount of seawater stored in the seawater collection tank 800. ) May be provided. At this time, if the water level sensor 810 can measure the water level, it may be a mechanical type using a buoyancy or an electronic type to recognize the contact with water.

When the amount of seawater measured by the water level sensor 810 is less than or equal to a predetermined amount, new seawater may be introduced from the outside by opening the second valve 820 connected to one side of the seawater collection tank 800. Can be. At this time, the predetermined amount of seawater can be arbitrarily adjusted by the user, but should be adjusted in consideration of the speed at which seawater is desalted.

Meanwhile, similar to the first valve 620, the second valve 820 connected to the seawater collection tank 800 may also be formed as a solenoid valve interlocked with the water level sensor 810, and the second valve The power source for driving 820 may be electric energy stored in the capacitor 500 as described above.

Hereinafter, with reference to Figure 1, the operation of one embodiment of the seawater desalination apparatus according to the present invention will be described with respect to the flow direction of the seawater. 1 is a perspective view illustrating a desalination apparatus of seawater according to an embodiment of the present invention as described above.

First, seawater stored in the seawater collection tank 800 shown in the lower left of FIG. 1 is introduced into the heater 100 along the inlet pipe 300. At this time, since the cross-sectional area of the inlet 122 of the flow path pipe 120 is larger than the cross-sectional area of the inlet pipe 300, the flow rate of the sea water when the inflow of sea water is reduced.

As such, the seawater introduced into the flow path tube 120 is heated by absorbing thermal energy of sunlight irradiated by the reflective lens 110 while flowing along the flow path tube 120. At this time, the relationship between the amount of heat required to heat the seawater and the size of the reflective lens 110 is summarized as follows.

That is, the amount of heat required to raise 100 ° C. at 1 atmosphere of water is required at 539 cal / g. This is called heat of vaporization. Accordingly, when the amount of seawater passing per unit area of the flow pipe 120 is set to 500 mL and the time passing through the flow pipe 120 is 30 sec, the energy required to vaporize is 8,983 cal / sec. Converting it to watts requires 4.189 joules / cal * [watt * (joules / sec)], which requires 37,604 watts.

Therefore, assuming that the heat energy of the solar light supplied per unit area of the flow pipe 120 is 1,000 watts, the length of the flow pipe 120 needs to be about 30 m, and thus the length of the reflective lens 110 should be about 30 m. something to do. At this time, since such a length may be difficult to implement in one heater 100, as described above, a plurality of heaters 100 may be provided and connected in series.

On the other hand, while the seawater is heated while flowing along the flow path pipe 120, the light energy of sunlight is converted into electrical energy through the solar panel 150 located above the flow path pipe 120, and moves along the cable 152 And may be stored in the capacitor 500.

As such, the heated sea water flowing along the flow pipe 120 may be converted into steam and hot water, and the heated sea water and the converted steam and hot water may discharge the discharge pipe 400 connected to the outlet 124 of the flow pipe 120. Is discharged through.

Thereafter, the heated seawater and the converted steam and hot water may be temporarily stored in the storage container 600, and the temperature is measured by the temperature sensor 610.

At this time, when the temperature enough to separate the seawater and hot water and steam heated without problems in the separator 200 is measured by the temperature sensor 610, the first valve 620 is opened and the storage container 600 Heated seawater and the converted steam and hot water stored in the) flows to the separator (200).

However, if the heater 100 is not sufficiently heated to measure below the predetermined temperature as described above, the seawater heated through the return pipe 700 and the converted steam and hot water are allowed to flow back to the inlet pipe 300. do.

On the other hand, the heated sea water and the converted steam and hot water flows from the storage container 600 to the separator 200 are separated from each of the separator 200, the criterion is whether the sea water desalination. That is, the heated seawater and the converted hot water discharged through the first discharge hole 220 do not desalination, and thus contain a large amount of salt. However, the steam discharged through the second discharge hole 240 is desalted and contains a large amount of salt. I'm not doing it.

As such, the heated sea water discharged through the first discharge hole 220 and the converted hot water are sent back to the inlet pipe 300 through the return pipe 700 or to a place of use (not shown) where hot water is required. On the other hand, the converted steam discharged through the second discharge hole 240 is sent to a place (not shown) where fresh water is required through a cooler (not shown) that cools it again and converts it back into water.

On the other hand, the amount of the heated sea water and the converted hot water is sent back to the inlet pipe 300 through the return pipe 700 is less than the amount of sea water introduced through the first inlet pipe (300). Therefore, to compensate for this, a certain amount of seawater is provided from the seawater collection tank 800 to the inlet pipe 300.

At this time, the amount of seawater (S) in the seawater collection tank 800 will be reduced, the water level detection sensor 810 is measured, if the predetermined amount or less by opening the second valve 820 to open the seawater collection tank 800, the amount of sea water (S) to be replenished. By automatically replenishing the amount of seawater S in this way, it is possible to ensure continuity when the seawater continues to be desalted.

While specific embodiments of the invention have been described and illustrated above, it is to be understood that the invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the invention. It is self-evident to those who have. Accordingly, such modifications or variations should not be individually understood from the technical spirit and viewpoint of the present invention, and modified embodiments should be included in the claims of the present invention.
