Description

The present invention relates to a fixed electric water purifier that is effective in purifying and sterilizing water.

The present invention is a fixed electric water purifier, specifically, a DC power supply device and an electrolytic water purification electrode of a control panel are integrated, and water that contacts the purification electrode is sent to promote purification. The water purifier of the present invention is an improvement over conventional water purifiers and water purifiers and methods.

In general, chlorine is used as a disinfectant for water purification, but chlorine is not good for the human body and is not an effective and economical disinfectant. Cooling tower water tanks on large stores where many people gather, and popular hot springs, baths, and swimming pools are generally disinfected using chlorine-based oxidizers for water hygiene. Is very responsive and requires careful handling. With the growing interest in the natural environment, there are increasing concerns about the dangers of using chlorine.

It is well known that metal ions kill microorganisms such as bacteria and prevent the generation of algae. It is also known that copper ions and silver ions have a bactericidal effect and prevent breeding effect on bacteria and the like and prevent the generation of algae. It has also been found that zinc, aluminum and gold ions can be used for similar purposes.

Accordingly, an object of the present invention is to realize an improved water purifier that can be removed by the amount and type of water-infected bacteria and air-infected bacteria, both indoors and outdoors.

Further objectives are the addition of conventional disinfectants, chemicals and chemicals to pools, hot springs, baths, fountains, ponds, lake water, swamp water, and cooling tower water tanks. It is to realize an improved water purification device that purifies water with metal ions.

Another object of the present invention is to realize a water purifier having metal ions that creates many processes of a sterilization machine, aiming at surpassing the resistance ability of bacteria in a single disinfection method.

An object of the present invention is to realize a water purifier using a power supply device that uses a relatively low voltage and low outflow rate in order to realize an effective water purifying electrode that kills bacteria in the process of destruction by electricity.

The purpose of the present invention is to realize a water purification device that solves problems such as gas generation, corrosion, and safety by performing conversion from a high voltage input to a low voltage (eg, 6V) and electric control by a timer. Yes.

The realization of a water purifier that solves the disadvantages of conventional water purifiers is also an object of the present invention. Conventional equipment has mainly focused on the component configuration and equipment of the equipment, but the present invention provides a clue to solving the problem by realizing a unique idea for the water purifier and the entire process.

A further object of the present invention is to realize a water purification device that does not need to be moved and operated with a fixed water purification electrode or a DC power supply device necessary for it, and uses natural water flow to create movement and flow, By adopting our own special machinery, we eliminate the waste of the structure and realize the water purifier using moving water, although it is a fixed device type with higher performance and lower cost.

As described above, in the case of the conventional apparatus and method, the efficiency is somewhat poor in terms of using metal ions. Known conventional devices have been centered on coordination with complex electrical equipment to achieve desirable results. As a result, the apparatus is expensive and complex, requiring special installation and adjustment, and the manufacturing and operating costs are high.

Conventionally, in various sterilization / algae generation prevention devices, it is recognized that water purification equipment occurs at various water purification electrodes. These devices add excess sodium persulfate to the water in which copper ions and silver ions are emitted from the copper silver electrode in water, or circulate water made conductive by adding a sufficient amount of sodium chloride between the two electrodes. The anodic reaction product and water purification electrode current made in the above and the linear relationship between the treated water temperature are used. However, none of the prior art devices have identified an important and useful element that will enable the electrical destruction of bacteria revealed by the present invention.

Other known shortcomings seem to be due to the use of electrode voltage, and at least some of the shortcomings are due to problems with water purification electrodes such as excess gas generation and corrosion, and accumulation of floats and deposits on water purification electrodes. It is thought. As a result, efficiency is reduced, destruction, and the water purification electrode are repeatedly cleaned. Many of these problems have been dealt with by sacrificing efficiency and increasing the contact time of treated water and the residence time between water purification electrodes. However, the voltage potential is lowered and the time is controlled by a timer. I think that it can be solved by.

The present invention is to change the potential of the voltage according to the water environment by elongating the contact time of treated water or the retention time of purified water. It can be solved by incorporating a timer and controlling the time, and the main feature is to purify chemicals and disinfectants without adding them to water indoors and outdoors. The apparatus is a cathode means with a spiral wire cathode, an anode means with a solid electrode, and a soluble anode means made of a conductive material. The soluble anode is an alloy that supplies ions suitable for water purification during the ionization action, and the soluble anode is an elemental metal suitable for conductivity and made of a transition metal. The soluble anode is made of a conductive alloy of the metal group (copper, silver, gold, platinum, zinc, aluminum, titanium). . The cathode includes a plurality of electrodes, an anode and a cathode. The cathode is a spiral wire connected by a power supply unit, and the anode is surrounded by the cathode and incorporated in the device. The substrate includes means for providing an appropriate connection between the DC power supply / anode conductive connection and the cathode conductive connection. The water purifier comprises a DC power supply wired to the control panel, a soluble electrode including a copper silver alloy anode, and a suitable metal or alloy cathode. In order of the water purification method, a direct current power supply for operating electricity to the anode and cathode under the treated water surface is operated. First, the anode means is connected to the positive output terminal connected to the output of the power supply means. The anode means is made of a conductive element metal, and the cathode means is made of a conductive metal wire. The cathode means is connected to a negative output terminal connected to one output of the power supply means. While giving a water flow around the anode means and the cathode means, twisting the wire in a spiral shape so as to surround the anode means, supplying electricity from the power supply unit, thereby generating ions necessary for purification from the fixed power supply, It is to create copper ions and silver ions, which are enough metal ions to kill and suppress the generation of algae and bacteria in the water. Furthermore, the water purification device is fixed, the water purification is localized, the water flow can be sent by an action related to the water purification device, and includes the step of oxidizing the water by electron extraction and oxygen addition. The water purifier is equipped with a DC power supply purifier for the anode and cathode under the surface of the treated water as a DC power supply for the control panel. The anode and cathode are connected to the power supply through the DC power supply, and metal ions are generated from the molten anode by energization. means for, realizes a fixed electrical water purification apparatus for sterilizing purify water when thereby installed in the treated water.

The fixed electric water purifier of the present invention uses a natural water flow to create movement and flow with a fixed water purifying electrode and a DC power supply device of a control panel, and has the effect of solving the disadvantages of the conventional water purifier.

The conventional equipment has mainly focused on the component configuration and equipment of the equipment, but the present invention is based on a new original idea for the water purifier and the whole process, and at the end of the power supply as much as possible. A water purifier with a power supply that creates many processes of sterilization machinery has been realized.

1 to 6 show an embodiment of the water purifier of the present invention. This water purification electrode has been improved so as to realize a large amount of water purification by adapting to the water flow on the treated water and installing in the circulation area. By connecting the purified water portions of the present invention, the water flow is interlocked with the electrode device to enable partial water purification while sending a large amount of water.

The electric water purification electrode in the example enhances the application power of the present invention as a whole. FIG. 1 to FIG. 4 show a purifying device, which is an example in which an electric means is connected to a power supply unit. An appropriate power source is selected from the constant voltage timer control method and the voltage conversion control method shown in FIGS. 5 to 6 based on the amount of electricity required for water purification. The means such as the water purifier and the safety device can be detached from the power source.

The purification device has electrodes such as anode means and cathode means which are main electrolytic components. In an embodiment, the anode means comprises a soluble anode and the cathode means comprises a spiral wire cathode. The electrodes are sent by two types of power supply devices. One is to set the energizing time by timer control with a constant voltage and send the DC power to the anode and cathode, and the other is the voltage and current required for the water environment. Is sent from the converter to send the DC power to the electrodes.

As shown in FIGS. 1 to 4 , the water purifier is attached as an electric insulating substrate having four bolts forming legs at the four corners of the resin plate as a substrate, and hanging down to the center of the substrate. A cylindrical melting positive electrode rod made of copper or a copper silver alloy, a negative electrode made of a spiral metal wire arranged concentrically around the melting positive electrode rod, and water between the positive and negative electrodes It consists of a DC power source that sends a DC current controlled according to the amount of movement between both electrodes. Further, the spiral wire electrode is attached to those welded to a stainless steel plate at screw, and the end terminal of the negative pole, one end is attached bolts soluble anode rod within the circle center of the spiral wire It is attached and the mounting bolt is a positive terminal. Soluble anode rod can be replaced its removal in the reverse turning of the watch.

The anode is made of a metal alloy which is a conductive element metal. The composition of the anode is basically 88% copper, 2% silver and 10% zinc. Other ratios, alloys and conductive materials can be used for the anode. For example, the anode can be made of a suitable transition metal such as gold, platinum, zinc, aluminum, titanium, and the electrolytic water purification electrode of the present invention is made of a copper-silver alloy of the anode. The cathode is a conductive material (one of galvanized iron wire, stainless steel wire, titanium wire, etc.), and the cathode surrounds the anode so that water flows between the anode, the cathode and the cathode coil. As shown in FIG. 1 of the embodiment, a part of the basket is attached to the water purification electrode.

In the embodiment, a DC output power source of the control panel is a cable, and a plus is connected to the soluble electrode of the water purifier and a minus is connected to the spiral wire electrode. From FIG. 1 to FIG. 4, the connection terminal is a positive pole and the B terminal is a negative pole. The amount of electricity sent from the control panel to the purification device is controlled by a timer or voltage change to achieve the required water purification rate. The device is placed in the water so that a current flows from the power source through the electrode device and the water purification process occurs, and the control panel is arbitrarily installed. The water purification process includes ionization of metal ions. The process of the present invention uses oxidation (electrons are extracted, oxygen is combined with substances, and removed because patina and calcium are attached to the metal rod) and electric shock processes (bacteria die when they touch the electrode).

The device has a geometry electrode and a spiral wire cathode, which is coiled and creates a useful feature around a central solid metal anode. One important feature is that it naturally causes a flow of water in and around the coil of the cathode coil spring. This coil adjustment has a fairly large surface area per length and volume, making the contact time of microorganisms sufficient for electrical breakdown.

Another important feature is that it is easy to remove floating stones that accumulate on the cathode by the spring effect. The device is usually capable of natural water flow, or depending on the position of the device, for water from the pump device, circulation device flow. Depending on the state of the treated water, regular use and daily short-time use are possible. Water flows from the opening of the path to the other opening. The closed path is used in cases where the flow rate is too high for the coil opening due to water flow.

Once the desired ion level is obtained, the use of chlorine and other disinfectants is drastically reduced or unnecessary. Use of the disinfectant depends on the frequency of use of the device, the use of water, and other variables. Furthermore, after several weeks of continuous use, calcium adhering to the spring cathode decreases the efficiency of the water purifier and must be removed. Note that calcium accumulated in the spring cathode can be easily removed.

Tests have shown that the anode has been used up over several years, leaving only a thin electrode rod attached to a conductive bolt. To replace the anode, unscrew the original anode and install a new anode in that position. A screw connection is preferred, but other similar conductive connection means to connect the anode to the power supply are possible.

The present invention is not limited to a specific amount of water treatment. In the embodiment, it is used for a cooling tower water tank, as well as a fountain and a pond. Moreover, timer control and voltage control can be performed for energization of the water purifier.

Research on electrolytic electrodes using flat electrodes showed that the rate of killing microorganisms increased linearly with the output, and the voltage had a greater impact than the current even at the same power level. The study also shows that in order to kill microorganisms, the microorganisms need to approach and contact the electrode, confirming the importance of the surface area for the effectiveness of the water purification electrode.

Tests on these electrodes revealed that contact time with the electrode was important and the function of the combination of voltage, surface area, and volumetric flow rate while passing through the water purification electrode. In general, it has been found that a long contact time at a voltage level of 2V results in a very low flow rate to the water purification electrode. The conclusion can be drawn that the volume flow for effective disinfection usually needs to be much lower than that used for pools and hot spring facilities. The test results also show that the voltage can be increased without increasing the amount of power, the water flow through the water purification electrode can be increased, the contact time can be shortened, and control by timer operation and voltage control can be performed. Has been.

When factors such as voltage, surface area, and flow rate are properly used in the electrolytic electrode of the present invention, it is effective in killing Escherichia coli, Pseudomonas aeruginosa, pneumoniae, and Bacillus subtilis.

The cathode of the purification electrode of the present invention in the embodiment is in the form of a coil spring. The circular anode is wrapped around a coil spring. Thereby, the present invention has many new and useful features for an energetic purification electrode. By using a twisted wire, the surface area per unit length of the water purification electrode unit volume, which is a combination of the cathode and the anode, can be maximized.

Changing the distance between the cathode coil or wire loop changes to an open electrode that does not fix the water inlet / outlet of the electrode. If the space | interval of a coil is narrowed, it will become a closed type electrode from which water enters from one side, and comes out from the other, or a water purification path | route. The electrode may be open or closed as long as the electrolytic electrode is vertically oriented with a voltage of 6V or more and a natural flow of water occurs around the electrode upward, the volumetric flow rate around the electrode is low and the contact time is long.

The middle coil space is another embodiment combining an apertured electrode and a closed electrode. With this combined water purification electrode, water can flow in the axial direction quickly due to the relative speed of the purified water cell to the treated water.

Based on this public information, a technician in the art can determine the coil space in which water enters from the bottom of the cathode coil and realizes a closed electrode exiting from the opening. As described in the present description, a closed cathode is used when the volumetric flow to the cathode coil becomes too high due to water flow, or when it is less effective than a smaller volumetric flow.

It will be appreciated that the spring steel wire allows the coil electrode to expand and contract. The expansion and contraction creates a rotational movement of the wire, which causes the twisting force to be applied to the rocks and deposits that accumulate on the cathode. This twisting force warms the rocks and buildup, making it easy to remove from the cathode. Thus, manual cleaning of the electrodes is a convenient point of the coil spring type electrode.

The device can be installed in various places, and the improved water purification device does not require purification of the treated water with chemicals. The purification device in the embodiment is simple and simplest and uses a power source that is everywhere.

The present invention uses two processes for water purification, and is a cathode design that enables water flow, dimensional deviation, and easy cleaning.

Having described the details, those skilled in the art can make improvements without departing from the essence of the present invention. Thus, the scope of the present invention is not limited to the specific embodiments that have been described, but rather is determined by the appended claims and their equivalents.

One of the present inventions can be easily adjusted and selected using a timer attached to the device, while another device uses a method of changing the DC power supply without adding conventional chemicals or disinfectants to the water. Moreover, unlike the sterilization means by heating or the like, it does not require an accessory device, does not take a place, can be purified and sterilized, and can be widely used from a small scale to a large scale facility regardless of indoor or outdoor.
