Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water generation device that obtains water from moisture in gas.

BACKGROUND ART Conventionally, a device for producing fresh water using seawater as a raw material is well known as a seawater desalination device. There is also a water reuse treatment device that processes wastewater such as sewage to a high degree to produce highly clear water that can be reused, but this can also be considered a water production device in the same category as a seawater desalination device. can. That is, in all of these methods, a solution containing liquid water as a main component is used as a raw material to obtain water. For this reason, since these water generation devices use liquid water as a raw material, they cannot naturally generate water in places such as deserts where liquid water cannot be obtained at all.

Therefore, there is a need for a water generation device that can easily obtain water even in areas such as deserts where liquid water cannot be obtained, and such new water generation devices are being developed.

In other words, this new water generation device is a device that obtains water from moisture present in the atmosphere, and is a new water generation device that can generate water anywhere as long as the atmosphere exists. Of course, it is impossible to create water if there is no moisture in the atmosphere, but statistical data on climate and the results of the inventors' research show that even in the atmosphere of the huge desert in the central Arabian Peninsula, the air
There are 3 to 4 g of water in m ³ and water production is possible. Therefore, human activities can be carried out by obtaining water in barren land, and by using this water as irrigation, it is also possible to cultivate plants. In other words, this water production device contributes to expanding the living area of humans, and its significance is extremely large.

The basic principle of this water generation device is that the first step is to adsorb moisture in the atmosphere onto an adsorbent, and the second step is to heat the adsorbent that has adsorbed this moisture to remove the adsorbed moisture. is desorbed as water vapor, which is then led to a condenser and converted into water. At this time, the adsorbent simultaneously loses water and regains its adsorption capacity, so that the adsorbent is repeatedly used to adsorb moisture from the atmosphere. In this way,
Liquid phase water can be obtained continuously from the atmosphere.

A is provided close to the flow port 2a, and when the suction port side door 8a and the discharge port side door 9a are closed, the first housing portion 1A and the heating chamber 3a are connected through the flow port 2a.
A circulation blower 10b circulates the air heated in the heating chamber 3a through the circulation path formed by the heating chamber 3a to raise the temperature of the adsorbent packed bed 1a and desorb the moisture adsorbed on the adsorbent packed bed 1a. , like the circulation blower 10a, by closing the suction port side door 8b and the discharge port side door 9b, which are provided close to the circulation port 2b, the second housing part 1 is passed through the circulation port 2b.

This is a circulation blower that circulates the heated air in b to raise the temperature of the adsorbent packed bed 1b and desorbs the moisture adsorbed on the adsorbent packed bed 1b.
11a and 11b were connected at one end to communicate with a circulation path formed by the first storage section 1A and the heating chamber 3a and a circulation path formed by the second storage section 1B and the heating chamber 3b. Gas flow path, 1
Reference numeral 2 denotes a switching valve that can mutually switch the connection between the other end of the flow path 11a and the condenser 7 and the connection between the other end of the flow path 11b and the condenser 7. Reference numeral 13, whose function is indicated by a dashed line, is an air-open water tank for storing water obtained in the condenser 7, and reference numeral 14, which is indicated by a dashed line, is produced water.

Next, the operation will be explained.

In this prior art freshwater generating device, there are two storage parts.
Since the base is provided, when one storage part is performing the adsorption process (first process), the other storage part is performing the desorption process (second process), and after these processes are completed, By alternating and repeating these processes, water generation can be performed continuously. In the following description, the first accommodating section 1A
The following description will be made assuming that the second housing section 1B is in the adsorption process and the second storage part 1B is in the desorption process.

In the suction process in the first storage section 1A, first, the suction port side door 8a of the first storage section 1A is
and open the discharge port side door 9a, and open the second storage section 1B.
The suction port side door 8b and the discharge port side door 9b are closed, and the switching valve 12 is switched so that the flow path 11b and the condenser 7 are connected. Next, the adsorption blower 6 is operated to draw adsorption air into the first storage section 1A from the suction port, and the adsorption air is brought into contact with the adsorbent packed bed 1a accommodated therein to perform an adsorption process. At this time, air that has been dried due to adsorption of moisture by the adsorbent packed layer 1a is discharged to the outside through the ventilation chamber 5. On the other hand, when the first accommodating part 1A is in the adsorption process, it is desirable that the desorption process in the second accommodating part 1B is performed. In this process of attaching and detaching the second accommodating part 1B, the second accommodating part 1B
With the suction port side door 8b and the discharge port side door 9b closed, the circulation blower 10b is operated to heat the air in the heating chamber 3b in the heating chamber 4b while passing the air through the second air circulation port 2b. A circulation path formed by the housing portion 1B and the heating chamber 3b is circulated. Then, by the air heated in the heating chamber 3b,
The purpose is to heat the adsorbent-filled layer 1b in the second housing portion 1B to convert moisture previously adsorbed into the adsorbent-filled layer 1b into water vapor and desorb it. In this way, when water vapor is desorbed from the adsorbent packed bed 1b, the volume of gas in the circulation path increases due to the generation of water vapor due to desorption and the high temperature, and the volume of gas in this circulation path increases. The increased gas is
The desorbed water vapor is discharged into the atmosphere through the flow path 11b, the switching valve 12, and the condenser 7. At this time, the water vapor in the gas flowing out from the circulation path is condensed in the condenser 7 and stored in the water receiving tank 13, but the water vapor corresponding to the saturated vapor pressure determined by the temperature of the condenser 7 is together with the air. It is released into the atmosphere and becomes a loss. However, the second storage section 1B
And the air that was initially in the heating chamber 3b is
Since the amount of water vapor is small compared to the amount of water vapor that is desorbed, and of course the amount is limited, it is all exhausted by the water vapor that is generated one after another, and essentially only water vapor circulates in the above circulation path. . In this state where there is only water vapor, the pressure in the above circulation path is
Since it is open to the atmosphere via the condenser 7, the pressure is always about 1 atmosphere. Further, the gas circulating in the circulation path is only water vapor, and the amount of water vapor equivalent to the desorbed water vapor is pushed out to the condenser 7.
Here, it becomes water and is stored in the water receiving tank 13. In this way, the desorption process is completed when the water content of the adsorbent packed bed 1b is sufficiently desorbed.

The adsorption process and desorption process explained above are explained as follows:
By making the second accommodating parts 1A and 1B perform this process alternately, water can be continuously obtained from the moisture in the air.

In such a fresh water generation device according to the prior art, the flow path from which air for moisture adsorption is sucked into the first storage section 1A or the second storage section 1B and discharged to the outside is equipped with piping that increases pressure loss. Since it does not use any valves or valves, it is a desirable structure in terms of energy saving and miniaturization. By the way, if you want to make the shape so that it can be transported by a container, trailer, etc. with a limited loading capacity when the operation is stopped, and also to increase the water production capacity as much as possible, the first and second storage parts 1A, 1B, adsorption It is necessary to keep the shape of the blower 6 and the condenser 7 to a size corresponding to the fresh water generation capacity, while reducing the shape of only the flow chamber 5. As a result, the volume occupied by the adsorption blower 6 and the condenser 7 in the ventilation chamber 5 becomes large, causing turbulence in the flow of discharged air passing through the ventilation chamber 5, increasing pressure loss, and reducing the water production capacity. The problem was that it was not easy to increase the number of people.

This invention was made in view of the above-mentioned problems, and allows the adsorption blower and condenser to be stored in the ventilation chamber when the device is not in operation, and also allows the adsorption blower and condenser to be stored in the ventilation chamber when the device is not in operation. It is an object of the present invention to provide a water generating device which has a small size during suspension of operation and has a large fresh water generating capacity by making it possible to draw out the water from the ventilation chamber.
