Description Water Extraction Method and Water Extraction Device with Collection Function for Extracting Water from the Atmosphere Technical Field

The present invention relates to a water extraction method and a water extraction device having a collection function for extracting water from the atmosphere, and in particular, a water extraction having a collection function for efficiently extracting a large amount of water from moisture in the atmosphere. The present invention relates to a method and a water extraction apparatus. Background art

In today's global environment, various abnormal weather events have begun to occur, such as groundwater and river water reductions due to global warming, desertification, lack of rain or snow, heat waves, and local floods. In addition, the ecosystem is beginning to be affected. The EU Environment Agency has announced that 75% of the Anoreps glacier in Switzerland will disappear in 2050.

In Japan, the average temperature has risen by 1 ° C over the past 100 years, and in urban areas where heat island phenomenon is likely to occur, it has risen by about 3 ° C, and many people suffer from heat stroke. Although it is possible to improve this problem by greening or watering the roof of the building, in order to secure the water resources necessary for them, the conventional methods not only require a lot of cost, but also the water resources themselves. There is a problem because it consumes a large amount. Disclosure of the invention

The present invention provides means (method and apparatus) for obtaining water from moisture in the atmosphere without using conventional water resources.

The problem to be solved by the present invention is that a large amount of water can be extracted from moisture in the atmosphere. In addition, when using it, there will be no impact on the natural environment, and there will be no need for prior construction to obtain water, and any means (method, equipment) that anyone can easily obtain water will be available. Is.

The principle for extracting water from the atmosphere is to cool the substance and There is a natural phenomenon where moisture in the atmosphere aggregates on the surface and water droplets are generated. It is an object of the present invention to provide means (method and apparatus) for obtaining a large amount of water from atmospheric moisture by effectively applying this phenomenon.

There are eight main components of the present invention. These eight components will be explained specifically for each component.

The first element is for extracting water from the atmosphere. As this base material, a material having good thermal conductivity and corrosion resistance is selected. Aluminum, steel or stainless steel plates are good. In the following, this plate is referred to as the “heat conduction plate”.

The second element is that the surface of the heat conduction plate is made as a rough surface with as fine an unevenness as possible to increase the substantial surface area, and further, it is modified to a hydrophilic film to improve the wettability.

The third factor is to insulate the back surface of the heat conduction plate to reduce losses due to the diffusion of cold air.

The fourth element is that the heat conduction plate is small and has a large surface area, for example, an elliptical tubular shape. The heat conductive plate formed in a tubular shape is hereinafter referred to as a “water generator”.

The fifth element is a cooling device for cooling the water generating device. This decree device should be installed as close to the water generator as possible. Improves cold air propagation and reduces losses.

Explain the sixth element. In a dry area, even if water condenses on the surface of the water generating device, it immediately re-airs and it is difficult to obtain a large amount of water. Wet water needs to be collected before revaporization. As the thickness of the water adhering to the surface of the cooled hydrophilic coating increases, the thermal insulation of the water impedes the growth of the water layer. In addition, the surface area of the water film is reduced due to surface tension and adhesiveness, which are physical properties of water, and the actual surface area is reduced. When the thickness of water exceeds a certain level due to these phenomena, the effect of aggregating moisture in the atmosphere into water is reduced.

Therefore, it is important to collect water by scrubbing the surface with water using a slider such as a brush at an early timing. This means for scavenging is the key to the present invention, and a device for doing this is called a “water collecting device”, and the water extraction device of the present invention is equipped with this water collecting device. On the other hand, if the surface to which water is attached is left unattended for a long time, it will become dirty, vigorous, and bacteria will grow. Therefore, it is necessary to remove it quickly. It is desirable that the water collecting device should be antibacterial treated at all points where water comes into contact. The second factor is that the amount of water extracted from the atmosphere is closely related to the humidity and temperature of the atmosphere and the cooling temperature of the heat conduction plate. Humidity ・ Control device for controlling other devices by constantly measuring the humidity and temperature of the atmosphere with temperature sensors and automatically calculating the optimum conditions for obtaining a large amount of water under given environmental conditions It is necessary to have The water collecting device, the cooling device, and the like are operated in accordance with a command from the control device.

Explain the 8th element. The power source of each device is mainly a power generation device using natural energy, which can be operated even in places where there is no commercial power source. Natural energy includes sunlight, wind power, wave power, geothermal heat, biotechnology, etc., mainly DC power. On the other hand, commercial AC power can be used in consideration of driving on the building rooftop, rainy weather, and night. Therefore, the control device has A / D / C conversion capability. In consideration of unstable supply of natural energy, the control device includes a power storage device.

The main components (means) that compose the device for extracting water from the atmosphere are as described above. In summary, the water generation device, cooling device, water collecting device, control device, power generation device using natural energy, power storage device Humidity 'temperature sensor, etc., and a housing for incorporating these components (devices) is added.

The raw material consumed by the apparatus according to the present invention will be described. The main raw materials are air and natural energy. Even if the moisture in the atmosphere that is the raw material is consumed, the ocean, which accounts for about 70% of the earth's surface, reliably compensates for the humidity, so the relative humidity of the atmosphere on the entire earth remains constant, affecting the global environment. Never give. It goes without saying that the main energy sources are solar and wind power, which is good for the environment.

By cooling the heat-conductive and corrosion-resistant plate with good wettability by applying a hydrophilic coating, moisture in the atmosphere is condensed on the plate surface to efficiently generate adhering water. In addition, an apparatus for efficiently extracting a large amount of water from moisture in the atmosphere is provided by removing the attached water in the process of increasing the amount of attached water and in the state of a thin water film that is difficult to re-evaporate.

In addition, a plate having the hydrophilic coating on the outer wall of the building is laid by utilizing the heat of vaporization when the adhering water generated on the cooled plate re-airs and the synergistic effect of the cooled plate. This will provide a new cooling system for the entire building.

The water extraction apparatus according to the present invention is a means by which the necessary amount of water can be obtained simply by installing it. It is. Aside from the existing power generators using natural energy, the installation cost is low because almost no infrastructure development such as laying work or electric power work is required.

The method for transmitting the cold air to the water generator 30 is performed by bringing the cold air terminal 85 into close contact with the cold air receiver 41 of the water generator 30.

Since the refrigeration unit 8 1 may be an inexpensive refrigeration cycle unit for an existing refrigerator, a detailed description is omitted. Since there is heat dissipation due to heat exchange, the side of the cooling box 8 2 is provided with a heat dissipation port 8 6 that prevents rainwater from entering. The power supply to the refrigeration unit 8 1 is provided by inserting the cord plug 8 8 through the outlet bush 8 7 into the refrigeration unit outlet 1 1 0 provided on the side of the control box 90. The cooling temperature in the embodiment of the water extraction apparatus A is 20 ° C., and the power consumption of the refrigeration apparatus 81 is about 1.2 kW.

The power required to operate the entire system including the cooling device 8 1 is 1.5 kW. In order to obtain this from only the photovoltaic power generation device 140, in the case of a solar cell module currently on the market, Since it is 1 50 W, about 10 sheets are required. For day and night operation, the number of modules is 20 and a power generation system with an electric capacity of about 3 kW is provided.

The amount of water extracted per day depends on the relative humidity of the atmosphere, and is about 24.000 liters at 75% relative humidity, about 190 liters at 60%, and about 100 liters at 30%. To obtain a larger amount of water, 赛 Increase the area of the M guide plate 31 and increase the cooling temperature range, etc. Should be implemented.

The function of the water collecting device 60 will be described below with reference to FIG. 2 and FIG. The water collecting device 60 is the most important device for obtaining a large amount of water. The amount of time until the water on the hydrophilic coating surface 3 2 grows is about 60 minutes or less even under high humidity, and it remains attached without increasing even after waiting for more time. Can't get a lot of water.

The water collecting device 60 is a means for effectively using the time zone during which the water is rapidly growing by removing before the growth of the thickness of the adhering water on the hydrophilic coating surface 32 becomes dull. In this embodiment, the water thickness of the attached water is about 0.2 mm, and the water tank collector 60 is operated in a state where it is difficult to vaporize due to the surface tension and adhesive force of the water.

The configuration of the water collecting device 60 will be described. Explaining the main components from the outside: 1 brush 6 5 that serves as a slider, 2 pelts 6 3, a pair of rotating cylinders 6 1, 6 2, and 1 module 6 7 . This will be described in detail below.

First, the upper drive side rotary cylinder 61 will be described. A coupling 6 9, a rotating shaft 7 1, and a rotating cylinder 61 are connected by a fastener 70 to a motor 6 7 having a gear decelerating gear 6 8. A bearing 73 is fitted to the rotary shaft 71, and the bearing 73 is fitted to a housing 74 welded to the side plate 20. The rotating shaft 7 1 and the rotating cylinder 6 1 are supported by two metals 7 5, and the dynamic force of the motor 6 7 is transmitted to the rotating cylinder 6 1. To run the motor 67, plug the corded plug 7 7 through the outlet bush 7 6 into the mobile outlet 1 0 9 provided on the side of the control box 90.

The operation of the rotary cylinder 61 does not require speed but requires rotational torque, so the motor 67 has a gear portion 68 for deceleration. The lower rotating cylinder 6 2 is the same as the upper rotating cylinder 6 1, and the bearing 7 3, housing 7 4, metal 7 5, etc. are the same, but the rotating shaft 7 2 is compared to the rotating wheel 7 1. Long length. Since Moyu 6 7 and Gear 6 8 use existing commercial products, their detailed explanations are omitted.

The connection of the rotating cylinders 61 and 62 and the slider such as the brush 65 will be described. A pair of rotating cylinders 6 1, 6 2 provided at the top and bottom are connected and rotated by the two belts 63. The belt 63 is hooked on a belt hooking portion 64 of a concave groove provided in the rotary cylinders 61 and 62. The rotational power of the motor 6 7 is transmitted to the rotating cylinders 6 1 and 6 2 and rotates at the same speed. The brush base 6 6 is fixed to the belt 6 3, and the brush 6 5 is attached to the brush base 6 6 so that it can be attached and detached. brush The mounting position of 65 is the uppermost position in the center as shown in Figs.

The operation of the brush 65 will be described below. When an operation command is received, the brush 65 located at the uppermost center of the center slides clockwise on the inner wall of the water generating device 30 and temporarily stops at the lowermost position of the center. Immediately after the temporary stop, it returns to the original position via the same route and simultaneously slides counterclockwise to perform the same operation and then returns to the original position. One cycle is clockwise and counterclockwise.

Moyu 6 7 is an imperial type, which rotates forward and reverse. The water attached to the hydrophilic film surface 3 2 by one cycle operation is brushed off by the brush 6 5 and led to the flow path 3 6. An operation command to the motor 67 that drives the brush 65 is performed by a control device 100 described later that incorporates a program for maximizing the amount of extracted water.

The material of the brush 65 will be described. Brush 65 uses a fine brush with a wear resistance, resilience, and fiber. As for the physical properties, it is important that the brush 65 itself has water repellency that does not wet and has antibacterial properties that suppress the propagation of pacteria and the like. As an example, a nylon brush with a filler is used which has the above-mentioned characteristics and reduces the trouble of replacement and cleaning. In this embodiment, the brush 65 is used, but a sponge-like roll or a rubber plate may be used.

The contents of the control box 90 will be described with reference to FIG. Control box 9 0 is control device 1 0

0 and the power storage device 1 2 0 are stored. The control box 90 is composed of a safe box formed by a storage box 9 1, a lid 9 2, a hinge 9 3, a handle 9 4, a keyhole 9 5, and the like. On the side of the control box 90, there are a power receiving port and a supply port for the power used. AC outlets 1 1 4 for commercial AC power supply 1 3 0, and solar power outlets 1 1 5 for receiving DC power from solar power generation 1 4 0, wind power generation equipment There is an outlet for wind power generation 1 1 6 which is a DC power receiving port from 1 5 0. The reason why there are two DC outlets is that they can be used together in consideration of the installation location and seasonal variations.

Next, as the supply port, the outlet for MOTOR 6 7 1 10 9, the outlet for refrigeration equipment 8 1 1 0, the outlet for temperature sensor 4 3, the outlet for temperature sensor 1 1 2 , Thermo-hygrometer 1 1 There is a thermo-hygrometer outlet 1 1 3 for firewood. All of the above outlet groups are under the control of the control device 100.

The operation panel 1 0 1 of the control device 100 will be described. There are three ON — 0 FF switches for water extraction device A. One is a switch for the power consumption side. 8 1 is the operation switch that turns ON and OFF simultaneously. The second is two generators of natural energy, a DC switch 1 0 3 that turns on and off the power received from the generators 1 4 0 and 1 5 0. The third is an AC switch 1 0 4 that turns on and off power from a commercial AC power source.

The function of the control device 100 will be described below. The control device 1 0 0 centrally manages all devices and equipment in the electric system. The command control content for each device is obtained by collecting information from each device and each device, integrating and monitoring, and operating each device to maximize the amount of water extracted from the atmosphere under the given conditions. Maintain optimal condition. Hereinafter, the relationship between each device and the control device 100 will be described.

The amount of water extracted from the atmosphere is closely related to the cooling temperature of the water generating device 60 by the refrigeration device 81 and the humidity and temperature of the air. Cooling ¾S is the temperature sensor 4 3, and air temperature and humidity are accumulated from information from the thermometer 1 1 7, information on the electric power held by the power storage device 1 20, and a specific constant of the water extraction device A, etc. Automatic switching between the intensity of operation of device 8 1 and the cycle evening of water collecting device 60.

The refrigeration unit 8 1 operates strongly or weakly when the amount of power currently held by the storage device 1 2 0 is larger than the preset reference value, weakly operates near the reference value, and temporarily stops when the power is below the reference value. It will be in a standby state. When the amount of power recovers, if the power supply source that returns to strong operation is also used with commercial AC power, the AC power supply compensates for the shortage of DC power. When is satisfied, it automatically shuts off AC power and uses DC power.

Regarding the operation control of the water collecting device 60, the water generation phenomenon and concept will be described. The growth rate of the thickness of the wetting water on the hydrophilic coating surface 3 2 will depend on the relative humidity of the atmosphere. On the other hand, it is more effective to reduce the thickness of the water that is once collected by using the physical properties of the water, such as surface tension and adhesive strength. If the relative humidity of the atmosphere is 30%, it is 0. As a guideline, 0.18 mm for 90 mm and 60%, and 0.27 mm for 90%.

Considering the above phenomenon, the operation of the water collecting device 60 is about 15 minutes per cycle. In this example, the amount of water extracted per minute varies with the humidity of the atmosphere, but is approximately 6 6−20 0 cc, and the amount of water extracted per cycle is approximately 1 to 3 liters. If the power supply is low, the system automatically switches to a saving operation with a cycle of about 30 to 45 minutes. Power 2005/017074

10 When the supply recovers, the time per cycle automatically returns to 15 minutes.

The control for the power consuming device and the supplying device will be described. The consuming device includes a refrigeration device 81, a motor 67, a control device 100, a power storage device 120, a temperature / humidity meter 1117, a temperature sensor 43, and the like. There are natural energy generators 1 4 0 and 1 5 0 on the supply side, but since the power supply may become unstable due to various factors, the power storage device 1 2 0 that stores the generated power is installed. It is important to prepare. The control device 100 constantly monitors the supply and consumption of power and makes predictions, and commands each device to operate optimally under given environmental conditions.

The control device 1 0 0 controls each device to operate optimally in order to maximize the amount of water extracted from the atmosphere under the given environmental conditions. Hold it. Measures such as regular operation when the amount of electricity stored in the storage device 1 2 0 exceeds the consumption, saving operation or temporary stop when it is almost the same as consumption, and stop when it is less than the consumption . On the other hand, when DC power is shared by commercial AC power supply 1 3 0 and natural energy generators 1 4 0 and 1 5 0, DC power is always switched to normal and DC power is restored when the amount of stored power is restored. Switch to automatically. Note that the control device 100 has a change of A C / D C.

In order to visually discriminate the operating state of the water extraction device A, the operation panel 10 1 of the control box 90 is provided with four-color indicator lights. In addition, a glass window 96 is provided in the lid 92 of the control box 90 so that the indicator lamp can be seen.

One is the blue light 1 0 5, and the lighting of the blue light 1 0 5 alone indicates normal operation using DC power. When the DC power supply decreases, the system switches to saving operation, and the blue light 1 0 5 is reduced to indicate that it is in saving operation. Similarly, blue light 1 0 5 blinks even when DC power is insufficient, such as during initial operation. When the electric energy recovers, it switches to normal operation and returns from flashing to lighting to indicate that it is in normal operation. Switching between regular operation and saving operation is performed automatically.

The second green light 1 0 6 indicates that commercial AC power is being input. When the supplied power is AC and DC, both blue light 1 0 5 and green light 1 0 6 are lit. When AC power supply stops due to a power failure, the green light 1 0 6 blinks and returns to lighting when recovered.

The third yellow light 1 0 7 lights up to indicate a pause (waiting). DC required for operation • Turns on when power supply is insufficient, and turns off when power is restored. Blue light with the aforementioned saving operation

When 1 0 5 continues to flash, and when the amount of power becomes insufficient, the yellow light 1 0 7 lights up and the blue light 1 0 5 turns off. Blue light 1 0 5 and yellow light 1 0 7 are dedicated indicator lights for DC power.

The fourth red light 1 0 8 lights indicate that some abnormality has occurred. Red light 1

0 8, Blue light 1 0 5 and Green light 1 0 6 are lit at the same time, indicating that the system is not operating according to the preprogrammed control device 1 0 0 command. In this case, it is a display to encourage inspection and repair. If the power supply is sufficient but the device's Bragg is not plugged in properly, the red light 10 8 will flash. The flashing red light 1 0 8 alerts the user to do the correct preparation.

The flow path of extracted water and temporary water storage will be described. The water generated by the water generating device 30 reaches the outlet 35 by the water collecting device 60 and is discharged below the flow channel 36. The discharged water flows into the pipe 45 and is temporarily stored. As shown in FIG. 2, the soot pipe 45 is fastened together with screws 39 and nuts 40 provided at the outlet 35 of the water generating device 30. The configuration of the pipe 45 in the present embodiment is constituted by a pipe having the same length as that of the water generator 30 and a storage capacity of about 60 retorts. It has a length of 3.0 meters and an inner diameter of 16 centimeters. The width of the flow path 36 is narrow so that water does not re-evaporate. In this embodiment, the width of the flow path 36 is adjusted with a length of 38 mm so that the width is about 2-3 mm.

The water temporarily stored in the soot pipe 45 is discharged from the discharge port 48 by loosening the valve 46 from the faucet 47 provided in the soot pipe 45. Convenience is improved by providing multiple faucets 4 7. In this embodiment, as shown in FIGS. 1, 2, and 3, a water tank 50 is installed under the faucet 47. The water tank lid 51 is placed on the water tank 50, and the water tank lid 51 is provided with a lid hole 52. After the lid hole 5 2 is under the faucet 4 7, the valve 4 6 is loosened to obtain the water storage 5 3.

As an actual usage, we will explain the watering of the green space on the building roof as an example. As this watering method is preferably unattended automatic watering, it is necessary to set a watering time and water pressure, so a solenoid valve valve, a time setting timer, a pump and the tip are closed to provide a large number of fine holes. Use a combination of hoses or noises. A spare outlet 1 1 1 is provided to supply power to these auxiliary equipment. If you set the required watering time in the evening, Every time the solenoid valve opens, the pump operates, and water is sprayed from the fine hole of the hose described above. In addition to the above examples, there are many ships and mountain huts in addition to the dry areas.

Since the water extracted from the atmosphere is close to pure water, it is not a delicious drinking water as it is. By including mineral ions such as calcium, it is possible to make a delicious drinking water.桶 Pipe 4 5 In the pipe, 5 or more food-grade ore-based substances that not only elute calcium but also suppress the growth of various bacteria are introduced. Antibacterial treatment is applied to the inner wall of the tub tube 4 5. Examples of ores for food include barley and stones, which are commercially available.

Although the water extraction device A is mainly installed outdoors, it also functions as a large dehumidifier when used indoors or in a basement with high humidity. In this case, it goes without saying that the natural energy generators 14 0, 1 50, etc., which are the power sources, are installed outdoors, but it is preferable to use a commercial AC power source 1 3 0.

The operation of the water extraction device A will be described. For convenience of explanation, the installation location and the ambient conditions of the atmosphere are the rooftop of a building with commercial AC power, the main power generator uses a solar power generator 1 4 0, the temperature is normal temperature and the average relative humidity in Japan 60% The purpose of use will be explained as follows, taking watering of green plants on the building roof as an example.

To prepare for operation, plug the plug 7 7 of the mobile 6 7 into the mobile outlet 1 0 9 and the plug 8 8 of the refrigerator 8 1 into the outlet 1 1 0 of the refrigerator. Next, insert plug 4 4 of temperature sensor 4 3 into outlet 1 1 2 for temperature sensor and plug 1 1 8 of thermometer 1 1 7 into outlet 1 1 3 for humidity thermometer. Next, insert the DC supply puffer installed in the solar power generator 1 4 0 into the solar power outlet 1 1 5 and connect the AC power source 1 3 0 and AC outlet 1 1 4 on the building roof separately with an extension cord. Preparations before driving are complete.

The operation of driving will be described. Insert the key into the key hole 9 5 of the lid 9 2 of the control box 90 and unlock it, and pull the handle 94 to display the operation panel 1 0 1 as shown in FIG. The lid 9 2 is joined to the storage box 9 1 by the hinge 9 3. When the three switches of the operation switch 1 0 2, DC switch 1 0 3, AC switch 1 0 4 on the top of the operation panel 1 0 1 are turned on, the blue light 1 0 5 flashes or lights up, the green light 1 0 6 lights up and operation starts.

Shortly after the hydrophilic coating surface 3 2 begins to wet, 15 min. The first extraction water from the atmosphere is sent and stored in the pipe 45. Commercial AC power is used only at the start and when the storage capacity is below the reference value.However, if DC power from the power generator 1 4 0 is stored above the reference value in the storage device 1 2 0, the power used is It switches to DC power automatically and repeats this.

If the water extractor A is operated for 1 ¾, the bushing 65 will be depleted, the amount of extracted water will decrease, and the red light 1 0 8 will light up. This phenomenon is alerted to the user by the control device 100 judging that the rotational torque of the motor 67 has decreased due to the wear of the brush 65. In this case, replace brush 65 or adjust the brush height. The replacement frequency is set every two years as a guide.

On the other hand, if it is left without consuming water, the red lamp 1 0 8 lights and the operation stops automatically. In this state, since water has accumulated in the water generator 30, a large resistance is added to the operation of the brush 65, and the rotational torque of the motor 67 has increased beyond the specified value. When 0 is detected, a stop command is issued and the red lamp 1 0 8 blinks. This function stops water extraction if there is no demand for water. The amount of water that has reached the overflow from the opening 25 is about 8500 water, about 3-8 days.

The greening area on the building roof that can be covered by the water extraction device A will be explained. For example, if the amount of water required by the lawn is 0.5 liters per square meter per day and the average relative humidity of the atmosphere is 60%, the amount of extracted water will be about 190 liters per day, which is 380 square meters. Can handle up to 1 Torr. In addition, when many water extraction devices A are installed in urban areas and greening of the roof is progressing, it can be expected that the average temperature will be lowered as well as the beauty.

When water is vaporized, its volume expands to about 600 times, so it takes heat away from the surroundings and can be applied to cooling. Specifically, if the building is covered from the outside using the f¾i guide plate 31 having a hydrophilic coating surface 32 and the refrigeration device 81 is provided on the roof, the extracted water can be re-vaporized and cooled. In addition, the synergistic effect of the heat transfer plate 31 can provide a new cooling method for the entire building. Not only can electricity consumption be significantly reduced by cooling, it also has the effect of suppressing local temperature rise. It is economical because the heat conduction plate 31 can be used in place of the building wall and the aluminum or stainless steel often used for building materials can be used.

As a variation of expanding applications, the size of the heat conduction plate 31 can be set freely, so that the amount of extracted water can be increased or decreased, dehumidifiers in places with high humidity, and industrial processing that requires moisture such as paper and cloth. Equipment, melting snow on roofs and roads. In order to use for melting snow, heat conduction plate 31 and ¾ί are used. As a heat source, for example, by using underground heat by inserting heat transfer into the ground or a well, it is possible to provide a snow melting device that uses only natural energy and has a low running cost.

The underground temperature is 1 2 _ 18 ° C throughout the year. This temperature is recovered by heat transfer and sent to a heat conduction plate to melt snow and ice, and the surface of the guidance plate gets wet, so that snowfall is solved and drifted. As the heat source, indoor humidity or temperature by a heating device may be used.

When the hydrophilic coating surface 3 2 of the water generator 30 is made of titanium oxide, it will not only decompose and remove the dirt attached by photocatalysis, but also suppress the probability of bacteria. It is convenient for securing drinking water. A specific means for adopting the water extraction apparatus A can be achieved by installing an ultraviolet lamp at a position where the entire surface of the oxide film can be irradiated and lighting it.
