Description

  The present invention relates to a technique for obtaining domestic water, and more particularly to a technique for purifying fresh water.

  Conventionally, in the purification of domestic water, when there is a water source such as seawater or a reservoir, seawater or fresh water stored in the water source is converted into fresh water for drinking. For example, in the case of the technique disclosed in Patent Document 1, water sucked up by a pump from a water source is passed through a prefilter (removal of impurities) and an activated carbon filter (removal of odor) and then pumped to a reverse osmosis membrane module. And get fresh water.

  However, such a conventional water purification technique is premised on having secured a water source in advance. For this reason, when a water source cannot be obtained, domestic water cannot be obtained.

  On the other hand, Patent Document 2 discloses a technique for obtaining living water when there is no water source due to drought or the like. In the technique disclosed in Patent Literature 2, fresh water is obtained by collecting moisture in the atmosphere using a dehumidifier technique and purifying the collected water through a filter.

  Certainly, according to the technique disclosed in Patent Document 2, it is considered that domestic water can be obtained even in a place where there is no water source. However, since the technique disclosed in Patent Document 2 uses the technique of a dehumidifier, an action such as cooling, compression, or adsorption reduction is used for collecting moisture. For this reason, cooling and compression require a lot of energy to obtain moisture, and there is a problem that practicality is poor in terms of obtaining domestic water. In adsorption and reduction, moisture is collected using a desiccant or absorbent, and these are re-dried to maintain the dehumidifying function. For this reason, since the water | moisture content discharged | emitted from a desiccant or an absorber becomes water vapor | steam again, there exists the actual condition that collection as a water | moisture content is difficult.

  Therefore, an object of the present invention is to provide a fresh water purifying apparatus and a fresh water purifying method that suppress energy used for collecting moisture in the atmosphere and can secure domestic water by long-term continuous operation.

  In order to achieve the above object, a fresh water purifying apparatus according to the present invention comprises an outer part having a water replenishing filter that collects water molecules floating in the atmosphere, and water collection that attracts the water molecules in the atmosphere with a charge. And a water reservoir equipped with a purification filter that filters the water collected by the water collector.

  In the fresh water purifying apparatus having the above-described features, the water replenishing filter may be an electrostatic filter, and a prefilter for collecting dust in the atmosphere may be provided outside the water replenishing filter. In such a configuration, it is possible to efficiently collect water molecules by manipulating the electric charges charged on the fibers of the electrostatic filter. Furthermore, by providing the pre-filter, it is possible to prevent dust from adhering to the water refilling filter, and to reduce the number of collected water that is filtered.

  In the fresh water purifier having the above-described characteristics, the purification filter is a carbon filter, and the carbon filter is preferably arranged in a plurality of stages with different filtration particle sizes. By setting it as such a structure, the smell of the collected water | moisture content can also be removed. Furthermore, the collected water can be filtered stepwise, and the life of the filter can be increased and the purity of the filtered water can be increased.

  In addition, a fresh water purification method for achieving the above object is a fresh water purification method for collecting water molecules floating in the atmosphere using any of the above-described fresh water purification devices, wherein the water molecules attracted by charge attraction. A step of collecting the collected water molecules by clustering and dropping the collected water molecules as water, and a step of filtering the dropped water into fresh water. An electrostatic filter is used to collect the water molecules by collecting positive charges on the collection surface side.

  By adopting such a method, it is possible to suppress the energy used in collecting moisture in the atmosphere. Moreover, the water molecule which floats in air | atmosphere can be efficiently collected by concentrating a positive electric charge on the collection surface side of a water replenishing filter, and collecting a water molecule.

  According to the fresh water purifying apparatus and method having the above-described features, energy used for collecting moisture in the atmosphere can be suppressed. For this reason, it is possible to secure domestic water by long-term continuous operation.

It is a figure which shows the structure of the fresh water refiner | purifier which concerns on embodiment. It is a figure which shows the mode of the water replenishment filter and water molecule before the charge to a core material. It is a figure which shows the mode of the water replenishment filter at the time of charging to a core material, and a water molecule.

  Hereinafter, embodiments of the fresh water purifying apparatus and method of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the fresh water purifying apparatus 10 according to the present embodiment is roughly composed of a water collector 12 and a water reservoir 24. The water collector 12 is an element that plays a role of collecting moisture drifting in the atmosphere. As an example of a specific configuration of the water collector 12, the following can be cited.

  That is, the water collector 12 according to the embodiment includes an outer shell 14 and a core member 20, and the outer shell 14 is provided with a pre-filter 16 and a water supplement filter 18. An example of the prefilter 16 is a HEPA (High Efficiency Particulate Air) filter. The pre-filter 16 is disposed outside the water refilling filter 18 and plays a role of removing dust in the atmosphere that flows in with the water to be collected by the water refilling filter 18.

  Specifically, the HEPA filter is a kind of air filter used as a main filter in a clean room, and has a particle collection rate of 99.97% or more with respect to particles having a particle size of about 0.3 μm. It is defined as an air filter. Therefore, PM2.5 is a particulate material with a particle size of 2.5 μm or less, cedar pollen is about 30 μm, house dust such as mite dung is 2 to 5 μm, and most of the dust is collected. it can.

  Moreover, as the water supplement filter 18, an electrostatic filter etc. are employable, for example. Water molecules have a particle size of about 3 angstroms (0.0003 μm), and hydrogen atoms and oxygen atoms are bonded by the action of electronegativity and exist as polar molecules. For this reason, the positively charged hydrogen atom (δ +) is attracted to the negatively charged substance (δ−) by the action of the charge attractive force, and the negatively charged oxygen atom (δ−) is It is attracted to the positively charged substance (δ +). Therefore, it is possible to efficiently collect water molecules by controlling the electric charge around the fibers constituting the electrostatic filter.

  The core member 20 is a metal body disposed inside the outer shell 14 provided with the pre-filter 16 and the water refilling filter 18, and serves as a water collecting part that draws water molecules in the atmosphere by using the action of charge attraction. Play the role of For this reason, electric power is applied to the core member 20 so as to have a weak charge. In the embodiment, the outer surface is configured to have a positive charge (δ +). In addition, as a principle of the core material 20, what is necessary is just to follow principles, such as an electrostatic generator.

  In such a configuration, in the fiber of the water refilling filter 18 that employs an electrostatic filter, if the core material 20 is not charged, even if charges are scattered as shown in FIG. After the core material 20 has a positive charge, the core material 20 is polarized so that the negative charge is attracted to the core material 20 side, resulting in a form as shown in FIG.

  Further, the water molecules are oriented and polarized by the charge attraction of the core material 20 and their orientation is adjusted, and the negatively charged oxygen atom side is attracted toward the arrangement direction of the core material 20. Here, when water molecules try to pass through the water refill filter 18, the water molecules are attracted to the positive charges concentrated outside the fibers constituting the water refill filter 18 and are adsorbed by the water refill filter 18. In addition, the electric charge of the fiber of the electrostatic filter which comprises the water replenishment filter 18 is not lost by adhesion of a water | moisture content.

  Water molecules adsorbed by the rehydration filter 18 are aggregated and clustered and dropped as water droplets. The dropped water droplets are introduced into the water reservoir 24 provided at the lower part of the water collector 12 through the collecting pan 22.

  The water reservoir 24 plays a role of filtering the water collected by the water collector 12 and includes a purification filter 26 inside. The purification filter 26 may be a carbon filter, for example. Here, in the water reservoir 24 according to the embodiment, as shown in FIG. 1, a plurality of carbon filters having different grain sizes, that is, different filtration particle sizes, are stacked.

  The carbon filters to be laminated are preferably arranged so that the filtration particle size becomes finer toward the lower layer side. By setting it as such an arrangement structure, the water | moisture content introduced from the water collector 12 can be filtered in steps. Therefore, clogging of each filter can be suppressed and the life can be extended. Moreover, the purification degree of the fresh water after a process improves by performing filtration in multiple steps in steps, and can be made safer.

  In the water reservoir 24 equipped with such a purification filter 26, the water supplied from the water collector 12 is filtered by gravity drop and becomes fresh water for domestic water in the lower layer. For this reason, there is no energy used for filtration of collected moisture, and energy saving can be achieved.

  The domestic water stored in the lower layer of the water reservoir 24 can be discharged through the drain cock 28.

  Further, according to the fresh water purifying apparatus 10 having such a configuration, energy used for collecting water is only a small amount of electric power for charging the core material, and energy saving can be achieved. For this reason, it becomes possible to secure domestic water by long-term continuous operation, and the present invention can be used as a fresh water refining device for securing drinking water at a construction site in a dry zone climatic zone adjacent to a desert or the like.
