Description

[0001] Apparatus for producing distilled water using solar heat [0002]

More particularly, the present invention relates to a device for producing distilled water using solar heat, and more particularly, to a device for producing distilled water using solar heat, wherein water contained in a lower tank is heated by solar heat through a heat collecting plate and evaporated in the form of water vapor, and the water vapor is condensed by temperature difference with water contained in the upper tank The present invention relates to an economical and eco-friendly apparatus for producing distilled water using solar heat, which can naturally produce distilled water through a water receiver and thereby recover the distilled water.

Generally, distilled water is a colorless transparent and tasteless odorless water in which impurities are removed by distillation of natural water. It is used not only as a water for chemical experiment or pharmaceutical production but also for drinking water .

Such distilled water can be simply produced by heating water using electric energy, but it is not only polluting the environment due to the use of electric energy, but also being economically inefficient.

Thus, as described in Patent Document 1 below, a distilled water producing apparatus having a structure and a form for producing distilled water by condensing water vapor obtained by heating water using solar energy as a natural energy has been filed and patented.

However, in the apparatus for producing distilled water described in Patent Document 1, the heat of the hot water storage tank is heated to make hot water by the solar heat collecting plate, the hot water is physically circulated along the outer side of the distillation tank to indirectly heat the water filled in the distillation tank, Which has a complicated structure, which is not easy to manufacture and causes energy loss, resulting in a problem in that the efficiency of producing distilled water deteriorates.

In other words, this structure is not a method of making the hot water of the hot water storage tank heated by the heat collecting plate as distilled water, but indirectly heating the water in the distillation tank by using the hot water as a heat source to make distilled water. The heat energy is lost in the process of indirectly heating the water in the distillation tank.

In order to solve the above problems, research and development of a distilled water producing apparatus having a structure capable of minimizing energy loss with a simple structure while producing distilled water using an eco-friendly and economically efficient solar heat is urgently required.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side sectional view showing an apparatus for producing distilled water using solar heat according to a preferred embodiment of the present invention, and FIG. 2 is a front view showing an apparatus for producing distilled water using solar heat according to a preferred embodiment of the present invention.

1 and 2, an apparatus 100 for producing distilled water using solar heat according to a preferred embodiment of the present invention includes an evaporation water tank 10, a heat collecting plate 20, a cooling water tank 30, (40).

First, water (W) to be made into distilled water is stored in the evaporation water tank (10). This is because the water (W) having a water quality enough to be used as distilled water is stored at a certain level, And receives the heat energy from the heat collecting plate 20 for collecting heat.

The evaporation water tank 10 is made of a material having a high thermal conductivity so as to efficiently receive the heat energy from the heat collecting plate 20 to smoothly heat the water. The lower surface of the evaporating water tank 10 is formed of the heat collecting plate 20, And is preferably flattened.

At this time, it is preferable that a water supply pipe (11) and a water discharge pipe (12) are installed in the evaporation water tank (10) so that water can be replenished or replaced. In addition, at least two water level sensors 13a and 13b may be provided on the inside of the evaporation water tank 10 so as to maintain the water level within a predetermined range.

That is, when the water W of the evaporation water tank 10 is evaporated and the water level is lower than the water level sensor 13a, the water level sensor 13a detects the water level and controls the water to be supplied through the water pipe 11, When the water level of the water W rises to the height of the water level sensor 13b, the level of the water W is kept constant by controlling the water level sensor 13b to stop the water supply.

Next, the heat collecting plate 20 is installed in close contact with the lower portion of the evaporation water tank 10, and collects solar heat by irradiating sunlight to heat the water stored in the evaporation water tank 10 .

At this time, the heat collecting plate 20 may employ an existing heat collecting plate structure which is conventionally applied by those skilled in the art. However, the structure should be such that the water stored in the evaporation water tank (10) is sufficiently heated to exhibit the heat collecting ability to be evaporated in the form of water vapor.

It is preferable that the heat collecting plate 20 is relatively larger than the bottom area of the evaporation water tank 10 so that solar heat can be efficiently collected from the sunlight to be irradiated. That is, the area of the heat collecting plate 20 should be larger than that of the evaporation water tank 10 so that the edge of the heat collecting plate 20 may be exposed to the outside of the lower portion of the evaporation water tank 10.

The cooling water tank 30 is installed at a predetermined distance from the upper portion of the evaporation water tank 10 and stores the cooling water C therein so that the water in the evaporation water tank 10 flows into the heat collecting plate 20, And condensing the water vapor generated while being heated by the cooling water (C) to produce distilled water.

That is, in the process of contacting the water vapor generated by heating the water on the lower surface of the cooling water tank 30, the water vapor is condensed by the temperature difference with the cooling water stored therein to make distilled water.

At this time, the cooling water tank 30 is made of a transparent material through which the sunlight is directly transmitted so that sunlight can be irradiated to the heat collecting plate 20 as a whole.

In order to prevent the sunlight irradiated to the heat collecting plate 20 from being obscured by the cooling water tank 30 as much as possible, the bottom portion thereof is inclined downwardly corresponding to the average irradiation angle of sunlight from the front end to the rear end. It also functions to flow naturally from the front end to the rear end.

Although not shown, the cooling water tank 30 is rotatable through the operation of the rotating means with the rear end of the lower surface of the cooling water tank 30 as the central axis so that the inclination angle of the lower surface of the cooling water tank 30 can be adjusted to the angle of sunlight, .

That is, the rotation shaft is provided on the lower surface of the cooling water tank 30, and the rotation means is formed on the rotation shaft, so that the cooling water tank 30 is rotated by the rotation operation of the rotation means. At this time, however, the rotation space must be secured so that the cooling water tank 30 can rotate sufficiently.

The cooling water tank 30 is provided with an inlet pipe 31 and an outlet pipe 32 through which the cooling water flows and flows so as to maintain the cooling state of the cooling water, and the inlet pipe 31 and the outlet pipe 32 are connected to the outlet pipe (33) for cooling the cooling water flowing out to the inlet pipe (32) and supplying it to the inlet pipe (31).

Here, the evaporation water tank 10 and the cooling water tank 30 are interconnected by a transparent plate 50 so that the space between the upper and lower portions of the evaporation water tank 10 and the cooling water tank 30 is isolated from the outside and sunlight is transmitted therethrough and irradiated to the heat collecting plate 20.

The connecting plate 50 is further provided with an opening and closing door 51 for allowing an operator to access the inside of the evaporating water tank 10 and the lower surface of the cooling water tank 30.

The distilled water collecting receptacle 40 is installed to be spaced apart from the rear end of the lower surface of the cooling water tank 30 by a predetermined distance and collects the distilled water flowing down along the lower surface of the cooling water tank 30 .

At this time, it is preferable that the distilled water collecting receptacle 40 is formed in a semicircular shape having an open top and an inner concave shape so as to smoothly flow the recovered distilled water while maximizing the recovery area of the distilled water.

The distilled water recovered by the distilled water recovery receptacle 40 is finally recovered by recovering distilled water (not shown in the figure) and becomes usable for various purposes.
