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 inventors' research show that even in the atmosphere of the huge desert in the central Arabian Peninsula, 1 m ³ of air
There are 3 to 4 g of water in it, making it possible to produce fresh water. 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.

The air heated in the heating chamber 3b is circulated through the circulation path formed by the adsorbent packed bed 1b to raise the temperature of the adsorbent packed bed 1b.

This is a switching valve that can mutually switch the connection between the other end of channel 11a and condenser 7, and the connection between the other end of channel 11b and 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, the dry air with moisture adsorbed by the adsorbent packed layer 1a is exhausted to the outside through the exhaust 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, and the air in the heating chamber 3b is heated by the heater 4b while passing 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 desorbed, and of course the amount is limited, it is all exhausted by the water vapor that is generated one after another, leaving substantially only water vapor circulating in the circulation path. In this state where there is only water vapor, the pressure in the circulation path is always about 1 atmosphere because it is open to the atmosphere via the condenser 7. 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, where it becomes water and is stored in the water receiving tank 13. It will be done.
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 water adsorption air can be circulated without using valves with large pressure drop to open and close the suction ports and the discharge ports of the first and second storage portions 1A and 1B. Since the suction port side doors 8a, 8b and the discharge port side doors 9a, 9b are used, which can widen the path, this is a desirable structure in terms of energy saving. However, each time the first and second accommodating parts 1A and 1B alternately repeat the adsorption process and the desorption process, the moisture desorption heaters 4a and 4b are turned on and off, resulting in energy loss, which is still not effective in terms of energy saving. There is room for improvement, and furthermore, the suction port side doors 8a, 8
There was a problem in that the operations for opening and closing the outlet side doors 9a and 9b were also complicated.

This invention was made in view of the above-mentioned problems, and eliminates the need to use opening/closing means such as valves and doors to open and close the suction port and discharge port of the storage section.
Furthermore, the present invention aims to provide a water generating device that is excellent in terms of energy saving and operability by having a structure that does not require the heater for water desorption to be turned on and off.

38 is a mounting plate to which the motor 37 is attached; 39 is a motor that drives the suction blower 36; 39 is a mounting plate that communicates with the lower chamber of the first cylindrical body 25 and the lower chamber of the second cylindrical body 26 from the outside; 40 is a heater installed in the conduit 39; 41, indicated by a dashed-dotted line, is an AC power source connected to the heater 40; and 42, indicated by a dashed-dotted line, is a condenser provided to communicate with the conduit 39. A container 43 is used for circulating desorption gas through a circulation path composed of the lower chamber of the first cylindrical body 25, the adsorbent filling chamber 21, the lower chamber of the second cylindrical body 26, and a conduit 39. The blower 44 is the first cylindrical body 25
This is a motor that is attached to the first closing plate 34 of the lower chamber and drives the circulation blower 43. In addition, 4
5 is a pre-adsorption chamber formed by the upper chamber of the first cylindrical body 25, before the adsorption air sucked in by the adsorption blower 36 passes through the adsorbent filling chamber 21, and 46 is the second cylinder. 47 is a post-adsorption chamber formed by the upper chamber of the cylindrical body 26 after the adsorption air has passed through the adsorbent filling chamber 21; This is a pre-desorption chamber before the desorption gas circulating through the adsorbent filling chamber 21.
8 is a post-desorption chamber formed by the lower chamber of the second cylindrical body 26 after the desorption gas passes through the adsorbent filling chamber 21.

Next, the operation of the fresh water generator of this embodiment will be explained.

Here, the partition plate 23 of the adsorbent filling chamber 21 is stopped so as to be on the same plane as the first and second dividing plates 27 and 28, and the adsorbent 24 of the adsorbent filling chamber 21 absorbs moisture. It is described as being in a dry state without adsorption.

First, the adsorption blower 36 is operated to draw adsorption air into the pre-adsorption chamber 45, and the adsorption air is supplied to half of the adsorbent filling chamber 21 communicating with the pre-adsorption chamber 45, so that air is filled with the adsorbent. After being brought into contact with the adsorbent 24, it is discharged to the outside through the post-adsorption chamber 46.
In this way, when it is considered that the adsorbent 24 in the upper half of the adsorbent filling chamber 21 has sufficiently adsorbed moisture, the adsorbent filling chamber 21 is rotated by half a rotation by the drive of the motor 33, and the circulation blower is rotated. 4
3 and the heater 40 are activated. Then, the dried adsorbent 24 in the adsorbent filling chamber 21, which originally communicated the pre-desorption chamber 47 with the post-desorption chamber 48, now communicates with the pre-adsorption chamber 45 and the post-adsorption chamber 46. , adsorption blower 3 continues to operate
The adsorption process begins upon contact with the adsorption air supplied by 6. On the other hand, the adsorbent 24 that has adsorbed sufficient moisture in the adsorbent filling chamber 21, which was initially in communication with the pre-adsorption chamber 45 and the post-adsorption chamber 46, is transferred to the pre-desorption chamber 45.
and the post-desorption chamber 48, and a circulation path consisting of the pre-desorption chamber 47, the adsorbent filling chamber 21 communicating therewith, the post-desorption chamber 48, and the conduit 39 remains in this circulation path. The air is circulated by the circulation blower 43, heated to a predetermined temperature by the heater 40, and the desorption process is started. In this desorption process, the air heated to a predetermined temperature by the heater 40 causes the adsorbent 24, which has sufficiently adsorbed moisture, to rise in temperature, desorb moisture, and generate water vapor. Assuming that the water storage tank (not shown) is open to the atmosphere, a portion of the air remaining in the circulation path will expand into the conduit 39 due to the volume expansion due to the temperature rise of the air that occurs shortly after the start of this desorption process. It is forced out of the water tank into the outside air through a communicating condenser 42. Then, when the above-mentioned generation of water vapor starts, the residual air is gradually replaced by water vapor, and the pre-desorption chamber 47, the post-desorption chamber 48 and the conduit 3
The partial pressure of water vapor inside 9 gradually increases and soon reaches one atmosphere. The water vapor generated one after another reaches the condenser 42 through the same path as described above, but if the condenser 42 is sufficiently cooled to a temperature of 100°C or less, the water vapor but
It is 100% condensed into water and stored in the water tank mentioned above. In this way, after a predetermined period of time has elapsed, the adsorbent filling chamber 21 is rotated half a turn again, so that the adsorption process and the desorption process can be performed continuously. Therefore, unlike the prior art device, there is no complicated operation of opening and closing the suction port side door and the discharge port side door, and there is no need to turn the heater on and off. This device is superior in terms of operability and energy saving compared to other devices.

The method of operating the fresh water generator of the present invention is not limited to the method of the above embodiment, and various methods are possible. For example, the method of rotating the adsorbent filling chamber 21 is as follows:
In order to prevent mixing of adsorption air and desorbed water vapor, it is necessary to rotate intermittently so that the partition plate 23 and the first and second dividing plates 27 and 28 are on the same plane. There is no need to make 2 turns; other 1/3 turns or 1/6 turns may be used. Also,
The time interval of the intermittent rotation of the adsorbent filling chamber 21 is appropriately determined depending on the type of adsorbent 24, the temperature of the air, the required amount of fresh water generation, the amount of adsorption air introduced per unit time, etc., and is not particularly limited. .

Also, regarding the structure of the water generator of this invention,
The present invention is not limited to the structure of the embodiment described above, and various modifications can be made without departing from the spirit of the present invention. For example, the partition plate 23 of the adsorbent filling chamber 21
Divide the division into an arbitrary number of equal parts, and divide the first and second dividing plates 2 to correspond to this equal division angle.
By changing the dividing angle of the first and second cylindrical bodies 25 and 26 by 7 and 28, the adsorbent filling chamber 2
The ratio of the adsorption area and the desorption area in 1 is 1:2,
The ratio can be appropriately selected from 1:3, 1:4, 2:1, 3:1, 4:1, etc. depending on the type of adsorbent 24, adsorption conditions, desorption conditions, etc. Further, in this embodiment, both the pre-adsorption chamber 45 and the post-adsorption chamber 46 are provided, but it is not necessary to provide both, and it is sufficient to provide either the pre-adsorption chamber 45 or the post-adsorption chamber 46. When only the pre-adsorption chamber 45 is provided, the adsorption blower 36 is of a push-in type, and the post-adsorption chamber 4
If only the suction blower 6 is provided, the suction blower 36 may be of a suction type. Furthermore, if necessary, a filter and/or a current plate may be provided in the pre-adsorption chamber 45 or the post-adsorption chamber 46, and a current plate may be provided in the pre-desorption chamber 47 or the post-desorption chamber 48. Furthermore, the circulation blower 43 may be installed within the conduit 39. In addition, after the heater 40 is attached and detached, the chamber 48
It may be installed inside. In short, circulation blower 4
3 and the heater 40 are connected to a pre-desorption chamber 47, an adsorbent filling chamber 21 communicating therewith, a post-desorption chamber 48, and a conduit 3.
It suffices if it is within the circulation path consisting of 9 and 9. In addition,
In this embodiment, an electric heater is used as the heater 40, but it does not necessarily have to be an electric heater, and other heaters such as combustion exhaust gas, superheated steam, dowsam steam, etc. may be used. Further, as the condenser 42, a cooling method other than an air cooling method may be used. Further, in this embodiment, the belt 31 is used to rotate the adsorbent filling chamber 21, but it is not necessarily necessary to use the belt 31, and other means such as gears may be used. In addition, the adsorbent used in the adsorbent filling chamber 21 is molecular sieve 3A, molecular sieve 4A, and molecular sieve 5.
Any material commonly used as a solid adsorbent may be used, such as zeolites such as A, 10X, and 13X, silica gel, alumina gel, silica alumina, activated alumina, activated carbon, activated bauxite, and activated clay. Further, absorbents such as lithium bromide and lithium chloride that are generally used in the form of aqueous solutions can be used as adsorbents by being supported on a suitable carrier such as alumina or asbestos. These adsorbents can be used in the form of particles, spheres, pellets, doublets, etc. without any problem. Furthermore, it is also possible to form a so-called parallel passage type packed bed using a honeycomb-like adsorbent or the like. These adsorbents are selected by taking into consideration their adsorption characteristics, temperature and humidity, and the operating conditions for adsorption and desorption of these adsorbents are selected as appropriate depending on the adsorbent used, and there are no particular restrictions. .

In this embodiment, the case where the water receiving tank 13 is open has been described, but the case where the water receiving tank 13 is closed is closed, or it is opened initially and the air in the circulation path is substantially expelled and replaced with desorbed water vapor, and then the tank is closed. The present invention can be applied to any of the following.

In the above description, the present invention has been described with respect to the case where water is obtained using moisture in the atmosphere as a raw material, but it is not necessarily limited to the atmosphere.

A drive device for intermittently rotating a rotating shaft is provided, so that when the small chamber corresponding to the adsorption chamber is in the adsorption process, the small chambers corresponding to the first and second desorption chambers are in the desorption process. Since water is produced continuously, there is no need for the complicated operations of opening and closing the suction port side door and the discharge port side door, unlike in prior art water generation devices, and there is no need to turn on and off the heater. In terms of operability, there is no
It is also extremely superior in terms of energy conservation.
