1 is a view for explaining a saltwater desalination apparatus of a multi-stage structure using solar energy according to the prior art.

As shown in FIG. 1, the conventional multi-stage brine desalination apparatus 100 using solar energy includes at least one salt evaporation plate in the device, and the salt evaporation plate is disposed on the plate and one surface of the plate. Consisting of a wick formed, the portion of the brine flows toward the wick formed on one side of the plate and the other side of the plate, the brine evaporated from energy sources such as solar energy condensed into fresh water, condensed fresh water Has a structure flowing down the other surface of the plate.

For example, in FIG. 1, at least four or more saline evaporation plates may be provided, and each saline evaporation plate may be defined as first to fourth saline evaporation plates.

Looking at the configuration of the brine desalination apparatus including each of the brine evaporation plate in more detail, as follows. For the purpose of understanding in FIG. 1, the following 'one side' and 'other side' may be understood as the right side of each plate as one side and the left side of the plate as the other side.

The brine desalination apparatus 100 in the present invention is provided with a wick on one surface and the other surface is formed on one surface of the first plate and the surface of the first plate 111 on which the evaporation energy is supplied from an external energy source, and the brine flows. A first brine evaporation plate 110 including a first wick 112 for evaporating the flowing brine using solar heat, and a plurality of first brine elongations extending to one side of the first brine evaporation plate; The second to the second is installed so as to be spaced apart to correspond to the evaporation plate, the brine vapor evaporated in the wick of the brine evaporation plate of the front end evaporated and diffused, and condensed on the other side of the plate to form a drop of water to be stored along the bottom Four plates 121, 131, and 141 and the second to fourth plates 121, 131, and 141 are formed on one surface of each of the second and fourth plates 121, 131, and 141, and latent heat of condensation of fresh water condensed on the other surface of the plate, and an energy source from the outside. The second to fourth salt evaporation plate (120, 130, 140) consisting of the second to fourth wick (122, 132, 142) for evaporating the brine by the first plate to the fourth plate It is placed inside, and comprises a housing (not shown) surrounding the outside of the brine desalination apparatus.

That is, the conventional brine desalination apparatus 100 directly receives solar heat and evaporates the brine to obtain fresh water by evaporating the brine by using the solar heat to evaporate the brine flowing down the wick. Later in the brine evaporation plate (120, 130, 140), the latent heat of condensation that is released when the evaporated brine vapor of the front end is formed on the other surface of each plate 121, 131, 141 as well as the solar heat conducted from the brine evaporation plate of the front end Can be used to evaporate the brine flowing in the wick.

Each of the brine evaporation plates (110, 120, 130, 140) includes a brine tank (114, 124, 134, 144) for supplying the brine to the wick provided on one surface of each plate, stored in the brine tank The brine flows into the wick, causing some to evaporate.

In addition, each brine evaporation plate (120, 130, 140) of the next step except the first brine evaporation plate has a structure including a fresh water tank (123, 133, 143) that can store the distilled water flowing on the plate have.

For reference, in the above description, for the sake of understanding, the conventional brine desalination apparatus 100 has been described as being composed of four saline evaporation plates. In fact, a plurality of saline evaporation plates may be further installed using the same principle as described above.

In addition, for convenience of description, in FIG. 1, the intervals between the brine evaporation plates are shown to be wider. However, in order to condense the brine evaporated from the brine evaporation plate at the front end, or to use the heat of condensation as a heat source for salt evaporation. The brine evaporation plate is installed closer than that shown in FIG.

As described above, the conventional multi-stage brine desalination apparatus 100 has to arrange each brine evaporation plate closely with a neighboring saline evaporation plate for an efficient desalination mechanism. The deterioration efficiency of the desalination may occur because the plates of the brine evaporation plate adjacent to and adjacent to each other are contacted by a structural defect or an accidental situation such as an accident.

That is, in order to produce fresh water in the multi-stage brine desalination apparatus, the wick in the brine evaporation plate at the front end and the plate at the rear end may be closely arranged and should not be in contact with each other. The reason is that the evaporated brine, that is, fresh water, forms on the plate and collects into the fresh water tank. If contacted with the wick of the brine evaporation plate installed at the front end, the brine flowing through the contacted wick is mixed with the fresh water on the plate. This is because salt is mixed in freshwater collected in the freshwater tank.

In addition, in the conventional brine desalination apparatus as described above, the plate constituting the brine evaporation plate is heat-transfer well, and because it is made of a structurally durable hard material, that is, a metal plate, etc. There is no choice but to go out with a lot of volume, and there is also a hassle to prepare a separate configuration of the brine pocket and the fresh water pocket, which are configured together with the plate and the wick. In this case, there are problems such as limitations in installation space, increase in manufacturing cost of the device, and initial construction cost, and in addition, it is possible to modify the appearance of the salt evaporation plate due to the hard material plate. There was a disadvantage that cannot be modified.

The brine desalination apparatus of the present invention is designed to solve this problem, and in the saline desalination apparatus having a salt evaporation plate having a multi-stage structure, it is not contacted with neighboring wicks in which fresh water is condensed and stored on each neighboring plate. This solution solves the problem of desalination efficiency by mixing fresh water and salt water at fixed intervals between the salt evaporation plates at appropriate intervals without interference, and also reduces the cost of manufacturing and constructing the salt water desalination device consumed by hard plate. To reduce.

As a first aspect of the brine desalination apparatus of the present invention, the present invention provides a plurality of brine evaporators for extracting fresh water by evaporating brine using solar heat or condensation heat, and at least one of the brine evaporators As one side of the evaporation portion is brine flows, a part of the brine evaporates, the other side is a salt water desalination apparatus comprising a housing surrounding the plurality of salt water evaporation portion, the fresh water generated by the condensation of the evaporated brine flows, Here, the housing flows along one surface of the brine evaporator and the brine outlet for outflowing the brine not evaporated; Fresh water outlet for allowing the evaporated brine vapor to be condensed on the other surface of the brine evaporation unit to the fresh water flowing down along the other surface to the outside; A front support that receives solar heat; And a rear support provided at the rear of the housing to fix the brine evaporator, wherein at least one brine evaporator of the plurality of brine evaporators includes a wetted part of which one part of the brine evaporates while the brine flows. The other surface is a water-resistant coating formed by condensation of the salt water evaporated from the neighboring wetted portion flowing downward; the core surface made of a flexible material (flexible), and each of the brine evaporator disposed in parallel spaced apart from each other Spacer is provided between one surface of the brine evaporation unit and the other surface of the neighboring brine evaporation unit for the purpose.

For reference, the configuration of the brine desalination apparatus of the present invention was defined differently to the name of each component in order to explain differently from the conventional brine desalination apparatus shown in FIG.

More specifically, the brine desalination apparatus of the present invention, evaporate the brine by using solar heat, or brine to extract fresh water by evaporating the brine using the heat of condensation (condensation latent heat) generated in the process of condensation of the evaporated brine A plurality of evaporation units are arranged in parallel in the housing, wherein at least one of the brine evaporation plates of one of the plurality of brine evaporators is partially brine as the brine flows, and the other side is generated by condensation of the evaporated brine. The fresh water has a structure flowing downward of the other surface, and comprises a housing 210 surrounding the plurality of brine evaporation.

On the other hand, the housing 210 flows along one surface of the front support 211 and the brine evaporation unit for receiving the solar heat to be delivered to the brine evaporator and the brine outlet 214 for outflowing the brine not evaporated, The evaporated brine vapor is condensed on the other surface of the brine evaporator, and is provided on the fresh water outlet 213 that allows outflow of fresh water flowing down along the other surface to the outside and the rear of the housing to fix the brine evaporator and the components of the housing.

For example, the remaining brine evaporator 300 except for the leftmost brine evaporator and the rightmost brine evaporator in FIG. 2 may include a core surface and a spacer 330.

Here, the core surface is a material that can be separated without mixing each salt water and fresh water so that one side corresponding to any one of both sides flows the salt water and the other side is fresh water flow It can be used without limitation.

The core surface in the present invention is made of a flexible material, and together with the spacer forms a technical feature of the salt water desalination device of the present invention, through which has the advantage of folding or bending the salt water desalination device.

It is advantageously possible to produce, and also has the advantage of mass production of a large number of products in a limited time.

For example, one side of the core surface is composed of a wet part 320 in which part of the brine evaporates while the brine flows, and the other surface is generated by condensation of the brine evaporated in the wet part 320 of the other brine evaporators arranged in parallel. The salt water is composed of a waterproof coating 310 flowing downward.

It is made to flow to the waterproof coating 310, which is the other surface of the brine evaporation.

Here, the front support 211 in the housing 210 may be made of a transparent material in order to receive solar heat and deliver it to the brine evaporator, but is not limited thereto.

On the other hand, the side surface of the brine evaporation portion of the front support may include a wetted portion and further configured to include a brine outflow portion so that the brine can be evaporated more efficiently.

In this case, even in the left-most brine evaporation portion in Figure 2 the core surface may be configured to include both the wet and waterproof coating.

In the brine evaporator 300 disposed thereafter, the brine flowing from the wetted part 320 is evaporated by using the heat of condensation emitted while the solar heat conducted from the brine evaporator at the front end and the evaporated brine form into a liquid phase, respectively. Fresh water formed on the waterproof coating 310 of the salt water evaporator flows to each fresh water collecting unit 350 to be collected.
