Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to at least two water purifiers capable of performing foreign water purification treatments connected in series by a water supply pipe to separate harmful solids, harmful chemicals, bacteria, viruses and the like. The present invention relates to a central water purification method and apparatus and a water purification management system for purifying water and performing soft water treatment at a desired rate as necessary.

[0002]

2. Description of the Related Art At present, it is difficult to completely remove or completely sterilize harmful chemical substances, disinfection by-products, protozoa, viruses, and the like in water purification plants. Therefore, a water purifier is attached to the necessary faucet to purify water for drinking water and cooking water.

[0003]

In view of the above-mentioned inadequacy of water purification at a water purification plant, most of the water purifiers attached to necessary faucets have a filtering function and an adsorbing function, but are small and close to the faucet. Large size is not adopted because it is installed. Therefore, of course, the water purification capacity is small, and it is difficult to say that the water purification capacity is perfect, and no germicidal lamps are used.
It has been known that sterilization and removal of bacteria, viruses, and the like are difficult.

[0004]

The present invention has solved the above-mentioned conventional problems by connecting two or more water purifiers having different purifying functions in series by a water supply pipe.

That is, the invention of the method is that water to be purified is sent at a predetermined pressure, and solid substances and harmful chemical substances are removed continuously and bacteria and viruses are sterilized by successively different water purification treatments. This is a central water purification method characterized by the following. Further, the invention of the device is a central water purification device characterized by having a water purification line in which at least two water purifiers capable of performing foreign water purification treatment are connected in series by a water supply pipe. A central water purification apparatus characterized in that a soft water treatment line and a bypass line thereof are connected in parallel to a water purification line in which at least two water purifiers that can be performed are connected in series by a water supply pipe.

Next, another invention of the present invention relates to a water purifying line in which a suction side of a water pump is connected to a water tank with an automatic valve, and a discharge side of the water pump is connected in series to a plurality of water purifiers. This is a central water purification system characterized by being installed side by side, with the suction side of the water supply pump connected to a water tank with an automatic valve, and the discharge side of the water supply pump connected to a plurality of water purifiers in series. A central water purifier characterized by connecting soft water lines interposed in parallel with each other, and having a bypass pipe arranged in parallel with the line connecting the water purification line and the soft water line. The plurality of in-line water purifiers have a pore diameter of 50 to 20 microns on the outside and 1 on the inside.
A first water purifier having at least two layers of inner and outer filter tubes having a pore diameter of 0 to 1 micron, a second water purifier having a high-performance filter tube obtained by sintering fine powdered activated carbon in a matrix, and a germicidal lamp. A third water purifier is connected in series with a water pipe to form a water purification line.

[0007] Next, the invention of the system, water to be purified,
By sending water at a predetermined pressure, successively purifying water of different quality, at least installing a sensor at a necessary place such as a water pump, an intermediate processing unit, etc., and inputting the output of the sensor to a control system for quantitative analysis. A centralized water purification management system characterized in that the measurement analysis data storage means and the transmission means are added to each other and connected to the management position or individually transmitted by an instruction.

[0008] The primary purpose of the first water purifier is to filter relatively large solids contained in the water supply, but it does not prevent adsorption filtration. Therefore, the filter medium is not limited to a two-layer filter medium having micropores, and a sintered cylinder having micropores, a sintered cylinder having micropores, or a multilayer synthetic paper filter can also be used.

The second water purifier mainly has a main purpose of adsorbing harmful chemical substances or adsorbing ultra-fine particles, but adsorbs minute particles and mixes a far-infrared ray emitting substance to perform far-infrared treatment or is useful. It does not prevent a multipurpose filter medium from being expected to elute minerals by mixing mineral-containing substances. If it is preferable to avoid mixing,
The second and third water purifiers are expected to have the above-mentioned respective effects, and a germicidal lamp can be installed in the fourth water purifier. Further, a germicidal lamp and a filter medium can be provided in the third water purifier of the present invention.

The germicidal lamp according to the present invention is for sterilizing bacteria, viruses and the like contained in the water supply. ) Need to be irradiated.
Therefore, the continuous irradiation distance must be determined in consideration of the intensity of ultraviolet rays and the flow rate of water supply. For example, in the case of a flow path having a cross-sectional area of 40 cm ² , when continuous irradiation is performed over 100 cm, the flow rate is preferably 20 cm / sec or less (provided that the water purification capacity is 40 liter / min).

[0011] It has been found that, when an aeration stone is put into the water tank of the present invention and treated for a certain period of time, the wave value of water is improved, which has a favorable effect on the body. In addition to the above-mentioned gaseous stones, it is also possible to use multi-element lava (for example, Nanjing barley stone) having the same function (Tables 1 and 2).

[0012]

[Table 1]

[0013]

[Table 2]

[0014] Specifically, if a certain amount of the above-mentioned gaseous stones is put in a water tank (for example, about 1/5 to 1/10 of the water tank capacity), it is eluted by water supply and mineral addition is automatically processed. Is done.

[0015] The precision press filter used in the first water purifier of the present invention preferably has at least two layers, and preferably has a larger outer pore and a smaller inner pore. By changing the diameter of the pores as described above, it is possible to cut off the steady flow of the passing water (change the flow velocity) and improve the filtration efficiency. For example, a layer having pores of 25 microns can filter some solids less than 25 microns in size, as well as solids greater than 25 microns in size. In the same manner, a layer having a pore diameter of 1 micron allows a solid substance having a size of 1 micron or more, of course,
Solids less than 1 micron in size can also be filtered to some extent. Therefore, the outer layer having a pore diameter of about 25 microns
The use of an inner layer on the order of microns can substantially achieve the purpose of solids filtration, but does not prevent three layers (for example, 50 microns, 25 microns, 1 micron) or four layers. However, it is necessary to obtain necessary filtration capacity and filtration efficiency in consideration of the thickness of each layer and the pressure loss due to an increase in the number of layers.

The second water purifier of the present invention is equipped with a high-performance filter in which, for example, activated carbon of fine powder is sintered into a matrix to increase the filtration capacity and the instantaneous flow capacity, and dissolves harmful substances contained in the water supply. Chemicals (eg pesticides, pesticides,
A disinfectant and its by-products) and solids up to about 0.5 microns.

Although the present invention removes harmful solids, gases and dissolved substances in water, the treated water is usually almost odorless. Therefore, if a fragrance favored by the user is added after the treatment with the third water purifier, an arbitrary fragrance can be imparted, alleviating mental tension and improving various psychosomatic disorders. For example, lavender incense, lemon incense, rose incense,
Jasmine scent, peppermint scent and others can be used according to personal preference. Specifically, the purpose is achieved by dropping the liquid in the pipe after the third water purifier.

The water softening line, which is a component of the present invention, includes a cartridge having a water softening function incorporated in the final step of the water purification process. In this case, by branching through a branch valve that can control the flow rate immediately before the soft water line, the hardness of the purified water can be arbitrarily set in conjunction with the branch valve.

The soft water cartridge in the above is usually
It is composed of a cartridge type filter or a housing type tank equipped with a cationic ion exchange resin capable of removing positive ions (magnesium ions, calcium ions, etc.) in purified water. Further, an ultraviolet germicidal lamp may be installed in the soft water cartridge.

The present invention has a built-in control box having functions of control, metering, and reporting, general control of water pumps (ON, OFF, water pressure, germicidal lamp, etc.) and quantification of information from various sensors. It has the function of catching abnormal signals and transmitting to telephone lines. More specifically, the equipment in the control box receives information from sensors such as water turbidity, PH, concentration of specific chemicals, electric conductivity, and water pressure in addition to general controls such as a water pump and an ultraviolet germicidal lamp. The measurement system is used to notify the maintenance system center using a telephone line together with the abnormal signal, stably maintain the high performance of the water purification device, and provide a 24-hour remote maintenance system for complete backup. The automatic device adds an appropriate check function (for example, periodically analyzes a part of purified water) and automatically monitors whether or not the operation is normal.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention continuously removes solid substances and harmful chemicals and sterilizes bacteria and viruses by sending water to be purified at a predetermined pressure and sequentially performing foreign water purification treatment. It is a water purification method to be performed.

[0022] Further, the present invention is a water purification apparatus in which a plurality of water purifiers for performing foreign treatments are connected in series by a water supply pipe, and a soft water treatment is performed if necessary.

Next, a sensor is installed in a water pump, a plurality of water purifiers, and the like, and the output of the sensor is input to a control system to perform weighing analysis, and a storage means and a transmitting means for the weighing analysis data can be added for remote management. It is a water purification management system.
