The present invention relates to a water purification method for liquefying and collecting water vapor by condensation and condensation of water vapor using water condensation in which water vapor in the atmosphere forms water droplets on a surface of a cold object, and a water purification device therefor.

In recent years, as the overall standard of living has improved, most people are paying close attention to water and air as essential to life, as well as medicine and food.

In response to this, air purifiers and water purifiers are widely used in homes or businesses for obtaining cleaner air and clean drinking water. A double air purifier is a device that purifies polluted air and converts it into fresh air. Contaminated air is passed through the air cleaning filter using a blowing means to collect and remove dust, bacteria and various odor molecules.

In general, the air cleaning filter is a mechanical filter using maltprene or glass fiber. B) high-performance filters for collecting particulates using glass and cellulose fibers, and deodorizing filters using activated carbon.

A water purifier is a device that changes raw water, such as tap water, into water quality standards in accordance with Article 5, paragraph 3, of the Drinking Water Management Act, which is classified according to purpose and composition. Integer through

That is, the raw water such as tap water is first obtained with a water purifier, and then filtered through a filtration step in which impurity particles in the water are filtered out by a precipitation filter, and an adsorption step in which volatile organic substances are removed by a carbon filter is performed. After the main filtration is performed by reverse osmosis membrane filter or hollow fiber membrane filter, it is discharged from the water purifier and supplied to the user.

However, conventional air purifiers and water purifiers are separate devices having different configurations, and thus, in order to obtain clean air and purified water in homes or workplaces, they have to be purchased separately, which requires a large cost and requires a large installation area.

Although a technology that integrates the functions of an air purifier and a water purifier has recently been introduced, this is merely a simple physical arrangement of a conventional air purifier and a water purifier in one outer case. In principle, it is merely a separate function.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a cross-sectional structural view schematically showing a water purification device (hereinafter, simply referred to as a water purification device) using an air cleaning process according to the present invention, which will be described later into each of the casings 2 forming an external shape. A blowing means 20, a cooling unit 30, an air cleaning filter 40, a collecting tank 56 and a water filter 60 are mounted.

To this end, the casing 2 has a duct region 4 in which the above-described elements can be built, an air inlet 6 through which air is sucked in, an air exhaust port 8 through which the sucked air is discharged, and a purified water discharge. The outlet port 10 is provided, for example, the inlet port 6 and the exhaust port 8 may be formed by opening the front and rear surfaces of the casing 2, respectively, and the outlet 10 may be formed from one side of the casing 2. It can protrude outward in the shape of a tube. Preferably, at least one intermittent valve 80 is provided at the outlet 10 to control whether the purified water is discharged.

And the air blowing means 20 is located between the internal inlet 6 and the exhaust port 8 of the casing (2), although not shown in the separate drawings, the power driven motor and the inlet ( It is provided with a fan 22 which intakes outside air | atmosphere through 6), and discharges it to the exhaust port 8 of the rear side.

In addition, the cooling unit 30 is located in front of the blowing means 20, the surface of which maintains the temperature below the dew point of the atmosphere.

Therefore, the outside air sucked by the blowing means 20 is discharged to the exhaust port 8 after contacting the cooling unit 30, during which the water vapor in the atmosphere has a surface temperature of less than the dew point surface temperature 30 It condenses to the surface and forms condensation. This condensation occurs when the water vapor in the air comes into contact with a colder object, and the relative humidity becomes higher, and when the dew point reaches the dew point, it forms as water droplets. It is a common phenomenon in glass.

In this case, in order to increase the dew condensation rate of the water vapor, the cooling unit 30 preferably maintains the surface temperature below the dew point as large as possible in contact with the atmosphere, and may have a configuration shown in FIG. 2.

2 is a plan view briefly showing the cooling unit 30 of the water purification apparatus according to the present invention, in which the dew point toward one end of the inlet 32 is zigzag bent in a predetermined shape so that the contact area with the atmosphere is large. It may have a form of a circulation tube discharged to the outlet 34 of the other end after the refrigerant of the following temperature is introduced, the material may be a metal such as aluminum or stainless steel that has a high thermal conductivity and prevent corrosion.

At this time, although not shown in the separate drawings, by adding an expansion valve or the like to one end of the cooling unit 30 in the form of a circulation pipe to vaporize and expand the refrigerant, it is also possible to absorb the heat around the cooling unit 30. The shape is not limited to the shape of the pipe as mentioned above, but can be free as long as possible to maximize the contact area with the atmosphere.

Next, as shown, at least one or more air cleaning filters 40 are arranged between the blowing means 20 and the cooling unit 30, so that the air sucked by the blowing means 20 is cooled with the cooling unit 30. It is discharged to the outside through the exhaust port 8 in the rear through the air cleaning filter 40 in sequence.

As described above, the air from which the internal water vapor is removed by condensation on the surface of the cooling unit 30 is purified by passing through the air cleaning filter 40, and the structure of the air cleaning filter 40 is outlined. Is shown in FIG. 3.

As shown in the drawing, at least one air cleaning filter 40 includes a microstructured filtration filter, a hepatic filter (High Efficiency Particular Air Filter) composed of electrified fibers, a deodorizing filter containing activated carbon, and titanium dioxide (TiO _2). At least one selected from photocatalyst filters or a combination thereof may be used. Preferably, the filtration filter 42, the hepa filter 44, the first deodorizing filter 46 and The photocatalyst filter 48 and the second deodorization filter 50 may be used.

At this time, the filtration filter 42 has a microstructure structure made of synthetic resin and the like, and serves to filter out dust having relatively large particles from the atmosphere, and to extend the life of the HEPA filter 44 to be described later. The high-efficiency hepa filter 44, which is used in a clean room or a spacecraft of a semiconductor production process, removes fine dust, mites, viruses, mold, and the like, which are harmful to a human body through strong adsorption power.

In addition, the first deodorizing filter 46 and the second deodorizing filter 50 preferably have different types of tissue structures, each containing activated carbon, not only the odor in the air, but also smoke, pet smell, toilet smell, It strongly adsorbs and removes garbage and other harmful gases to freshen air, and the photocatalyst filter 48 contains titanium oxide having strong oxidation power on the microfiber structure interwoven vertically and laterally of aluminum, so that nitrogen oxides in the atmosphere, Oxygen decomposes and removes organic compounds such as exhaust gas, various bacteria and odors. Therefore, the air is cleansed during the process of passing through the at least one air cleaning filter 40.

At this time, the at least one air cleaning filter 40 may be irradiated with ultraviolet rays to the purified air through an ultraviolet lamp 52 interposed therebetween. As is well known, ultraviolet rays cause strong chemical and physiological effects of Escherichia coli and diphtheria. Fungi, dysentery, etc. can be sterilized. Accordingly, as shown in the drawing, the ultraviolet lamps 52 may be arranged at the rear end of the at least one air cleaning filter 40 to clean the air finally discharged to the outside through the exhaust port 8.

In addition, at least one or more of the air cleaning filter 40 and the ultraviolet lamp 52 can be expected to have the same effect even if it is located between the blowing means 20 and the exhaust port 8, unlike the air blowing means 20 It will be apparent to those skilled in the art that the position may be any one between the cooling unit 30 and the blowing means 20 or between the blowing means 20 and the exhaust port 8 as long as the inhaled atmosphere is passed. In addition, by interposing a prefiltration filter 54 having a microstructure structure that blocks the inlet port 6 in front of the cooling unit 30, the condensation water formed on the surface of the cooling unit 30 may be cleaner and the air cleaning efficiency may be improved. Enhancements will also be readily appreciated by those skilled in the art.

On the other hand, the water droplets formed on the surface of the cooling unit 30 described above drop in the direction of gravity as the condensation gradually progresses, and the collecting tank 56 is disposed at the lower end of the cooling unit 30 to collect the condensation water. It is provided. To this end, the collecting tank 56 may have a bowl shape having an upper surface opened as an example, and a pipe passage 58 leading the collected water to at least one water filter 60 at the bottom surface thereof. Is formed.

FIG. 5 shows an example of a portion of the pipe line 58 and at least one water filter 60 connected thereto, in which the precipitation filter 64, the precarbon filter 66, and the condensation water pass in order. The hollow fiber membrane filter 68 and the post carbon filter 70 may be arranged.

In this case, each of these filters is briefly mentioned. First, the sediment filter 64 is filled with a synthetic resin fibrous structure having micropores on the order of several micrometers, and is relatively free from raw water such as various suspended substances such as rust, soil, sand, and dust. The large particles of impurities are filtered out, and the precarbon filter 66 is filled with activated carbon to absorb and remove odors and volatile organic substances such as chlorine (trihalomethane) using its adsorptive properties.

In addition, the hollow fiber membrane filter 68 is filled with a microfiber structure (ultra filtration) having a pore size of about 0.01 ~ 0.04 μm, which is also commonly called an ultrafiltration membrane, to pass the mineral components beneficial to health instead of filtering the remaining impurities cleanly. Finally, the post carbon filter 70 removes residual odors, tastes, pigments, etc. using activated carbon.

Through this process, the condensation water collected in the collecting tank 56 is changed to a drinking water. In this case, since the water pressure may be lowered during the process of passing through each filter, the pipe passage 58 in front of the water filter 60 It is preferable that the pressure reduction pump 62 be installed. In addition, the water purification tank 72 is connected to the post carbon filter 70 in which the purified water is finally discharged to store the purified water, so that the purified water can be supplied when the user needs the purified water tank ( 72 may be provided with a cold water tank 74 and a warm water tank 76 which are connected to the branches from each other to store the purified water, and then cool and heat the water according to a user's preference, thereby discharging cold and warm water.

For this purpose, although not clearly shown in the drawings, it is obvious that the cooler and the warm water tank 76 may be provided with a cooler and a heater, respectively. And preferably, the water level detection sensor 78 is installed in the purified water tank 72 to maintain a constant water level by controlling the circuit breaker 79 in conjunction with the pressure pump 62 of the pipe line (58).

The above description is summarized with reference to FIGS. 1 to 5 and FIG. 6, which is a flowchart of a water purification method using an air cleaning process according to the present invention.

First, the fresh water growth value according to the present invention starts as the first blowing means 20 is activated to inhale the atmosphere around the inlet 6 in front of the casing 2. (st1)

The air sucked in this way is brought into contact with the cooling unit 30 with the dust and the like removed through the pre-filter 54 installed at the suction port 6, and the surface of the cooling unit 30 has a temperature below the dew point. As it is retained, water vapor in the atmosphere condenses on its surface, forming condensation (st2).

Subsequently, the air from which the water vapor is removed while passing through the cooling unit 30 is purified during the process of passing through the at least one air cleaning filter 40. Preferably, the air is sterilized by ultraviolet rays irradiated from the ultraviolet lamp 52 to exhaust the exhaust port. It is discharged to the outside through 8), the user can get clean air (st4).

On the other hand, water droplets condensed on the surface of the cooling unit 30 are collected in the collecting tank 56 at the lower end (st5), and the condensation water collected in this way is at least one purified water filter 60 by a pressure pump 62 or the like. After being purified in the course of passing through (st5) it is collected again into the purified water tank 72. The purified water is stored in the cold water tank 74 and the warm water tank 76 and then provided to the user.

In this case, when the cold and hot water tanks 74 and 76 are provided as shown in FIG. 4, the outlets indicated by reference numeral 10 in FIG. 1 are divided into a first outlet 10a and a second outlet 10b for discharging cold purified water, respectively. It may be, and each of the intermittent valve 80 attached to each may be divided into a first intermittent valve (80a) for regulating the discharge of cold water and a second intermittent valve (80b) for regulating the discharge of warm water, This will be extremely obvious to those skilled in the art.

The purified water generation method according to the present invention described above and the purified water generation method therefor is characterized by the largest feature of producing a drinking water purified by liquefying and collecting water vapor in the atmosphere by using the dew condensation during the air cleaning process, The advantage is that water can be generated without the need for a separate source of external water, such as tap water.

Therefore, it can be used anywhere without place restrictions. For example, if there is a certain amount of water vapor in the atmosphere can be used in a place without the supply of raw water, there is an advantage to obtain clean air.

The purified water growth value according to the present invention is very different from the general water purifier and its principle, so the application range is very large, and because it obtains drinking water purified by using the air cleaning process, it takes up a small area and costs money for device configuration. It has the advantage of getting clean air and drinking water together.
