Abstract

PURPOSE:To improve desalting rate by forming an evaporating vessel consisting of a transparent plastic incorporating a sea water plate and a liquefying vessel consisting of a plastic film which is made laterally oscillatable by wind force into one body in the forward and backward direction. CONSTITUTION:The water level in a sea water plate 3 is maintained constant since the sea water supplied through a sea water feed pipe 6 into the plate 3 overflows from a sea water overflow pipe 7. The sea water in the plate 3 is heated to evaporate by the solar heat irradiated to the upper slope 1b of an evaporating vessel 1 and part of the steam is cooled by the upper slope 1b of the vessel 1 to form water drops which enter a trough and run to the front bottom of a liquefying vessel 2. The greater part of the steam ascends along the upper slope 1b and is filled in the vessel 2. The steam filled in the vessel 2 is cooled to water drops which fall along the inside wall of the vessel 2. The fresh water enters a fresh water storage chamber 12 from a delineating line 11.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for desalinating dσ water, hard water, sewage water, contaminated water, etc. using solar heat.

As a device that uses solar heat to produce fresh water from seawater,
Sunlight irradiates a seawater basin placed inside a greenhouse with a gabled or dome-shaped roof made of transparent material such as a glass plate or plastic sheet, and the greenhouse is filled with water vapor heated and evaporated by solar heat, creating a greenhouse. Micro droplets are formed on the inner surface of water vapor by iD,ti;i,
There is a known desalination device in which the droplets gradually increase in size and eventually flow down the slope of the greenhouse and are collected in a gutter placed at the bottom (Japanese Patent Application Laid-Open No. 15258-1525).
(See Publication No. 7). The above known desalination! A. In this case, it is difficult to maintain the temperature difference between the surface of the seawater basin and the surface of the greenhouse, which limits the amount of water evaporation. For this purpose, it is possible to increase the volume of the greenhouse, but in this case, the amount of water vapor remaining in the greenhouse will only increase, and the amount of water taken will not increase much. Increasing the volume of the greenhouse also has the problem of reducing the amount of solar heat that passes through because the glass plates and plastic sheets become thicker.

The present invention provides a desalination device that is relatively small in size and can extract a large amount of water.

That is, this invention is characterized in that a vaporization container molded from a transparent plastic material with a built-in seawater basin and a liquefaction container made of a plastic film that can be swung from side to side by wind force are integrally molded in the front and rear direction. This is a desalination device that

An embodiment of the present invention will be described below with reference to the drawings.

The desalination device is a device in which a vaporization container 1 and a liquefaction container 2 are integrally combined, and the vaporization container 1 has an intermediate box shape molded from a hard transparent plastic material, and has a downwardly curved portion 1a at the front. , an upwardly inclined part 1b at the top, an opening 1c at the rear,
A bottom plate 1d of the seawater basin 3 is formed at the bottom. The liquefaction container 2 is made of a plastic film and lies flat in a vertical hollow, with an opening 2a at the front that fits into the opening 1c of the vaporization container 1, an upwardly sloping section 2b at the top, and a rear and front lower part. A joint portion 2c extending downward is formed. 2. A spine 4 made of hard plastic runs from the inner surface of the front end of the vaporization container 1 to the inner surface of the upper center line of the liquefaction container 2.
is fixed to the spine 4a inside the liquefaction container 2, and several pairs of ribs 5 are integrally molded on the backbone 4a in the liquefaction container 2, opening downward and rearward to the left and right and branching to the middle of the liquefaction container 2. Therefore, the shape of the vaporization container 1 is relatively low in height but wide, and the shape of the liquefaction container 2 is high in height but the width gradually becomes narrower toward the rear. A portion of the liquefaction container 2 below the ribs 5 can swing freely in the horizontal direction. In other words, it is goldfish-shaped, with the vaporization container 1 forming the head and body of a goldfish, and the liquefaction container 2 forming the tail of the goldfish.

To explain the structure of the vaporization container 1 in more detail, the bottom of the vaporization container 1 is sealed by the bottom plate 1d of the seawater basin 3. The bottom of the seawater basin 3 is approximately circular or polygonal, and the front circumferential wall 3a is low and the rear circumferential wall 3b is high. A seawater supply pipe 6 that penetrates the bottom plate 1d is opened in the inner shaft of the seawater basin 3, and a seawater overflow pipe 7 that penetrates the bottom plate 1d is opened at the front end of the seawater basin 3.
is higher than the opening lower a of the seawater overflow pipe 7. A seawater overflow prevention wall 8 in the width direction is provided at the rear end of the bottom plate 1d of the seawater basin 3 to prevent seawater overflowing into the vaporization container 1 from flowing into the liquefaction container 2. Further, along the inner surface of the vaporization container 1, there are provided gutters 9 facing downward on both sides, and both lower ends thereof are open to the liquefaction container 2. In addition, the vaporizer container 1 is equipped with a cock 10.
is installed.

Next, to explain the structure of the liquefaction container in more detail, the lower part of the liquefaction container 2 has a partition line 11 which is melt-sealed in the front and back direction.
A freshwater front chamber 12 is formed, and several freshwater holes 13 communicating with the freshwater front chamber 12 are opened at the partition line 11.

The bottom of the freshwater anteroom 12 is connected to a freshwater collection pipe 15 through a soft tube 14 such as a rubber tube. Also, the joint 2c at the rear of the liquefaction container 2 and the freshwater anteroom 12 is made of a soft plastic film. A strip 16 is provided to help the liquefaction container 2 swing from side to side when the wind blows.

In the above structure, seawater (1 (seawater t from vas deferens 6;
Since seawater is supplied to the σ water basin 3 and overflowed from the seawater overflow pipe 7, the water level in the seawater basin 3 is kept constant. The seawater in the seawater basin 3 is heated and evaporated by the solar heat irradiated on the upwardly inclined part tb of the vaporizing vessel 1, and a part of the water vapor is cooled on the upwardly inclined part 1b of the vaporizing vessel 1, becomes water droplets, and flows down the gutter. The water vapor enters the liquefaction container 2 and flows to the front bottom of the liquefaction container 2. However, the water vapor enters the liquefaction container 2 through the upward slope A along the upward slope 1b of the liquefaction container 1.
filled within. Since the liquefaction container 2 is being swung from side to side by the wind, the inner surface of the liquefaction container 2 is relatively low temperature, and the filled water vapor is cooled and becomes water droplets, which fall along the inner surface of the liquefaction container 2, and the fresh water flows to the compartment line. 11, enters the freshwater front chamber 12 via the freshwater hole 13, and is further discharged from the freshwater four-water pipe 15 through the soft pipe 14.

In the above action, most of the water evaporated from the seawater basin 3 is cooled in the liquefaction container 2 and becomes water droplets, and these water droplets are
The side wall of the liquefaction container 2 is almost vertical, and the liquefaction container 2 is likely to fall because it swings from side to side. In addition, the fresh water contained in the fresh water regulation chamber I2 has a partition line II above it, and the submerged fresh water hole 13 at the partition line J1 is narrow, so that no backflow 1.3 is generated into the liquefaction container 2.

The cock 10 provided in the vaporization container 1 of the above embodiment performs various functions, such as supplying water for internal flushing [-1], finding damaged parts of the container by pressurizing air, and applying pressure to vibrate the film of the liquefaction container. used for.

In the above embodiments, the vaporization container is made of hard plastic, but the vaporization container is not limited to the materials listed above, and may be made of plastic film or flexible plastic sheet. . in this case,
In order to stabilize the shape of the vaporization container 1, it is preferable to attach ribs 5 to the spine 4 inside the vaporization container 1.

The inner surface of the seawater basin 3 is preferably black in order to easily absorb solar heat, and the liquefaction container 2 is preferably milky white in order to promote reflection of solar heat and reduce temperature rise.

Furthermore, in the above embodiment, the section I! provided at the bottom of the liquefaction container 2! The i-line 11 may be omitted.

The cylinder provided at the bottom of the bottom plate of FIG. Since the sand container 17 is heated and retained by solar heat irradiation, the seawater in the σ water supply pipe 6 is preheated and the sand container 17 continues to operate for a while even after L1 has died due to the heat retention of the sand container 17. I can do it.

Although the basic desalination apparatus of the above embodiment has been described, various modifications can be considered to improve the desalination efficiency. For example, the vaporization vessel can be enlarged and two liquefaction vessels can be placed symmetrically on either side of it. In addition, a strip of plastic fill 11 is hung from the spine and ribs of the liquefaction container, and the liquefaction container 8! The liquefaction efficiency can be further improved by arranging three I-bones in parallel and suspending a strip of plastic film to increase the liquefaction area of water vapor in the liquefaction container.

In order to put the desalination apparatus of this invention into practical use, several desalination apparatuses are arranged as shown in FIG.

The seawater overflow pipe 7 from the first device (right end) is connected as a seawater supply pipe to the next second device to sequentially concentrate seawater, while the freshwater collection pipe J5 from each device is collected into one pipe. It is preferable to operate so that the

In addition, several sets of the above desalination devices arranged in a plane can be arranged in stages to increase the size.

As explained above, the present invention is one in which a vaporization container with a built-in seawater basin and a liquefaction container made of a plastic film that can be swung from side to side by wind force are integrally connected in the front and rear direction. Therefore, the water vapor evaporated by solar heat in the vaporization container moves into the liquefaction container, where it is cooled and becomes water droplets, and the water droplets that land on the inner surface of the liquefaction container are promoted to fall by the ml movement caused by the wind in the liquefaction container. Efficiency is improved compared to conventional freshwater devices, particularly by increasing the surface area of the liquefaction vessel.
