DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

In addition, since the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, It is to be understood that equivalents and modifications are possible.

FIG. 1 is a view for explaining a conventional multi-stage salt water desalination apparatus using solar energy.

As shown in FIG. 1, a conventional multi-stage brine desalination apparatus using solar energy includes at least one brine evaporation plate in the apparatus, and the brine evaporation plate has a plate and a The brine is evaporated from the energy source such as solar energy and condensed into the fresh water to the portion where the brine flows down toward the wick formed on one surface of the plate and the other surface of the plate, Has a structure that flows down on the other surface of the plate.

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

The construction of the saline desalination apparatus including the respective salt evaporation plates will be described in more detail as follows. For the sake of understanding in FIG. 1, the right side of each of the below-described 'one side' and the 'other side' may be one side, and the left side of the plate may be regarded as another side.

The saline desalination apparatus 100 according to the present invention has a wick on one surface and a first plate on the surface of which the evaporation energy is supplied from an external energy source and the other surface of the first plate 111, A first brine evaporation plate 110 including a first wick 112 for evaporating the flowing brine using solar heat, a plurality of first brine evaporation plates 110 extending to one side of the first brine evaporation plate, And the second to the third plates are disposed so as to correspond to the evaporation plates, the salt water vapor evaporated in the wick of the salt evaporation plate at the front end is evaporated and diffused, and they are condensed on the other surface of the plate, 4 plates 121, 131, and 141 and the second to fourth plates 121, 131, and 141. The latent heat of condensation condensed on the other surface of the plate, And second to fourth brine evaporation plates (120, 130, 140) composed of second to fourth wicks (122, 132, 142) for evaporating the brine by the first to fourth plates And a housing (not shown) surrounding the outside of the desalination apparatus.

That is, in the conventional salt water desalination apparatus 100, the first salt water evaporation plate 110 for directly receiving solar heat and evaporating saline water to obtain fresh water evaporates the salt water flowing down the wick using the solar heat, In the subsequent brine evaporation plates 120, 130, and 140, not only the solar heat conducted from the salt evaporation plate at the front end but also the latent heat of condensation released when the evaporated salt water vapor at the front end is formed on the other surface of the plates 121, Can be used to evaporate brine flowing through the wick.

Each of the brine evaporation plates 110, 120, 130, and 140 includes brine tanks 114, 124, 134, and 144 for supplying brine to wicks provided on one surface of each plate, and is stored in the brine tank The brine will be partially evaporated as it flows into the wick.

In addition, each of the brine evaporation plates 120, 130 and 140 in the next step except for the first brine evaporation plate has a structure including fresh water tanks 123, 133 and 143 capable of storing distilled water flowing on the plate have.

For reference, in the above description, the conventional salt water desalination apparatus 100 is described as being composed of four brine evaporation plates. However, in practice, a plurality of brine evaporation plates may be installed using the above-mentioned principle.

In order to simplify the explanation, FIG. 1 shows an enlarged interval between the brine plates. However, in order to condense the brine evaporated from the salt evaporation plate at the front end, or to use the heat as the heat source for the brine evaporation, The brine evaporation plate is installed more closely than shown in Fig.

As described above, the conventional multi-stage brine desalination apparatus 100 is forced to arrange each of the salt evaporation plates closely to the neighboring salt evaporation plates for an efficient desalination mechanism. At this time, And the plate of the brine evaporation plate adjacent to the downstream side may come into contact with structural defects or due to an unexpected situation such as an accident, and the desalination efficiency may be lowered.

That is, in order to produce fresh water in the brine desalination apparatus having the multi-stage structure as described above, the wicks in the salt water evaporating plate at the front end and the plate at the rear end are closely arranged, but they should not be in contact with each other. The reason for this is that the evaporated brine, that is, fresh water, must flow into the fresh water tank on the plate, and if it comes into contact with the wick of the brine evaporation plate installed at the front end, the brine flowing through the wick to be contacted is mixed with the fresh water on the plate, This is because salt is mixed in the fresh water collected in the fresh water tank.

In addition, in the conventional salt water desalination apparatus, since the plate constituting the salt evaporation plate is made of a material which is heat-transferable and structurally strong and hard and hard, that is, a metal plate or the like, It is troublesome to manufacture the brine pockets and the fresh water pockets which are constituted together in the plate and the wick as a separate constitution. As a result, the volume and the weight increase due to such problems, There is a problem in that the installation space is limited and the manufacturing cost of the apparatus is increased and the initial construction cost is consumed. In addition, there is a problem in that the plate of the hard material is used to change the appearance of the salt water evaporation plate There is a disadvantage that it is impossible to deform.

The brine desalination apparatus of the present invention is designed to solve such a problem. In the brine desalination apparatus having the multi-stage brine desalination apparatus, fresh water is stored on each neighboring plate and is not contacted with neighboring wicks , It is possible to eliminate the problem that the desalination efficiency is reduced due to the mixing of the fresh water and the saline water by fixingly separating the respective salt evaporation plates at appropriate intervals without any interference, .

As a first aspect of the saline desalination apparatus of the present invention, the present invention is a saline desalination apparatus comprising: a plurality of saline evaporators for extracting fresh water by evaporating salt water using solar heat or condensation heat in parallel; The present invention relates to a desalination apparatus for desalinating a desalinated water, comprising: a desalination unit for desalinating a desalination unit including a plurality of desalination units, Here, the housing may include a brine outlet that flows along one side of the brine evaporator and discharges the unevaporated brine to the outside; A fresh water outlet through which the evaporated salt water vapor is condensed on the other surface of the salt water evaporator so that fresh water flowing downward along the other surface can flow out; A front support that accepts solar heat; And a rear support provided on the rear surface of the housing to fix the brine evaporator, wherein at least one of the plurality of brine evaporators includes a wetting portion in which a part of the brine evaporates as the brine flows through the one surface, And a waterproof coating portion in which fresh water generated by the condensation of the brine evaporated in the neighboring wet portion flows downward on the other surface, and a brine surface made of a flexible material and the brine evaporation portions arranged in parallel are separated from each other And a spacer provided between one surface of the brine evaporator and the other surface of the brine evaporator adjacent to the brine evaporator.

For reference, the constitution of the saline desalination apparatus of the present invention is different from that of the conventional saline desalination apparatus shown in FIG.
