Description

Underwater Sterilization and Disinfection Equipment Using Current Modulation Metal Ion

The present invention relates to a disinfection device using a metal ion and a method thereof, and more specifically, to a water used for various purposes and to a variety of structures in which such water is flowed or stored in a manner of mixing the metal ion in water The present invention relates to a sterilization and disinfection apparatus using metal ions to sterilize and disinfect contaminants such as microorganisms, lichens, and bacteria, which are grown in the stomach, and to prevent the generation of scale and the like by these contaminants.

In general, water is classified according to its use and use, such as industrial water, drinking water, and general water.These water flows through related devices, pipes, and chambers, or is accommodated and operated in various types of storage tanks including cooling water tanks. .

On the other hand, water usually contains contaminants such as microorganisms, moss, and bacteria, and these contaminants not only contaminate water but are formed on a scale that grows on the sidewalls of structures such as pipes and storage tanks. It is produced by other pollutants.

In addition, the scale formed by being deposited on the sidewalls of pipes and devices not only prevents the flow of water but also acts as a factor that interferes with the normal functioning of the devices.

As a conventional method for removing the contaminants of such a problem, a method of removing microorganisms, moss, and bacteria as an oxidizing component generated by continuously adding a strong oxidizing fungicide, that is, a chlorine fungicide, has been used.

However, the oxidized component generated by the chlorine disinfectant oxidizes components of the pipes and various devices, and at the same time, the oxidized metal materials and chlorine compounds are generated as pollutants that contaminate the water, and the water including the pollutants generated in the stream Or there is a problem that causes another environmental pollution when introduced into the groundwater.

Furthermore, recent research has revealed that chlorine organics are the main culprit of environmental hormones, and the problem of environmental pollution caused by environmental hormones is emerging at this time.

Therefore, in order to solve the above problems, research on sterilization and disinfection methods aiming at the use of chlorine disinfectants has been actively conducted. Examples of such methods include the formation of ozone to react with pollutants in water and the exposure of ultraviolet rays to water. Various methods have been introduced, such as decomposing pollutants or mixing a certain amount of metal ions with water.

Here, the apparatus and method for sterilizing and disinfecting by applying a power of different polarity to the disinfecting specific metal in the above-described method to dissolve the metal ion in water and to cause the metal ion to react with various pollutants This will be described with reference to.

First, as shown in FIG. 1, the conventional sterilization apparatus 10 using metal ions is provided with a rectangular tubular chamber 12 having a predetermined size partitioned on a flow line of water. At least one electrode portion 14 is provided in an upper portion of the chamber 12 in a cylindrical shape communicating with the inside of the chamber 12.

In the structure of this electrode part 14, the cylindrical manifold 16 is provided in communication with the upper part of the chamber 12, and the power supply line 18a, 18b and the transfer bolt (inside) of this manifold 16 are carried out. 20), the electrode plates 22a and 22b to which power of different polarities are applied are fixedly installed to face each other at regular intervals.

On the other hand, one end of the vent line 24 is connected to the upper portion of the manifold 16, a portion of the water flowing through the chamber 12 is vertically passed between the two electrode plates (22a, 22b), The other end of this vent line 24 is in communication with the inlet of the pump 26.

In addition, on the flow line between the vent line 24 and the chamber 12, a pump 26 for controlling the flow of water by a controller (omitted for simplicity of the drawing) and a flow sensor 28 for detecting the flow of water are provided. Is installed.

The above-described flow sensor 28 detects the flow of water guided to the chamber 12, and applies the detected signal to the controller, and the controller controls both electrodes through the signal detected by the flow sensor 28. The power required for the plates 22a and 22b is applied to regulate the generation of metal ions.

Therefore, the generation of metal ions is generated in response to the flow of water through the flow sensor 28, and when the flow of water is not detected, the controller is applied to both electrode plates 22a and 22b for generating metal ions. It is configured to cut off the power.

Looking at the operation process in the sterilization apparatus 10 using the metal ion of this configuration, the water flowing along the flow line is detected by the flow sensor 28, in response to the detected signal the control unit is a manifold (16) The metal ions are generated by applying the required power to both electrode plates 22a and 22b fixed to the < RTI ID = 0.0 >

At this time, the water flowing into the chamber 12 forms a main stream of water flowing in the flow line connected to the other side of the chamber 12, and at the same time, some of the electrode plates 22a, 22b installed on the upper part of the chamber 12 It is mixed with the generated metal ions passing through) to be introduced into the vent line 24, and the water containing the metal ions thus induced is mixed with the water is introduced into the chamber 12 again.

However, in the above-described configuration, the electrode plate fixed to the manifold is made of a material in which ionized metal is detached from the electrode plate as the water between both electrode plates acts as an electrolyte of the power source to which the electrode plate is applied. Accordingly, the thickness of both electrode plates is gradually reduced, resulting in a gap between the two opposing surfaces.

As a result of the gap between the two electrode plates is increased, the amount of current between the two electrode plates corresponding to the applied power source and the amount of generation of metal ions is reduced, thereby reducing the sterilization and disinfection ability of the water source.

In addition, there is a problem in that unnecessary power is gradually consumed in the process of forming a higher voltage state between the two electrode plates as a way to solve the above-described problem, and in the control unit, both electrode plates in response to changes in the water quality conductivity There is a problem that it is difficult to control the generation rate of the metal ion is not provided with a function to control the amount of current between.

Then, there is a risk that the bonding relationship between the electrode plate, which gradually decreases in thickness, and the transfer bolt that fixes the electrode plate is loosened, and there is a risk of separation. Therefore, the cumbersome use of replacing the electrode plate at regular intervals and the used electrode plate are used again. There was an uneconomic problem that could not be done.

In addition, as the water is filled in the chamber, the manifold and the vent line, the disassembly and assembly of each component is overflowed by the pressure state of the filled water in the chamber when disassembling the electrode plate including the manifold. There was a difficult problem.

On the other hand, according to the sterilization apparatus of the above-described configuration, it is configured to generate metal ions in response to the flow of water through the flow sensor, this configuration has a problem that can not control the content of metal ions corresponding to the total amount of water In addition, the flow sensor also has a problem in that it cannot produce the required amount of metal ions due to the fact that scale is formed or corroded when exposed to contaminated water for a long time.

In addition, since the electrode plate is not in contact with the main stream flowing through the chamber, the metal ions produced and the oxide film generated on the surface of the electrode plate are not effectively induced and discharged, and thus, it is difficult to expect a normal sterilization and disinfection function. There was a hassle to remount and use.

In addition, when the pressure inside the chamber is insignificant or low compared to the pressure of the flow line close to the pump inlet, the generated metal ions may not be sufficiently mixed with water, and the metal ions flowing through the vent line may also flow secondary. There is a problem that the metal ions are present on the manifold and the bent line due to the composition mixed with the main stream of the line, and supply is not performed.

The present invention is to adjust the interval of the electrode plate to generate a certain ratio of metal ions in response to the change in the conductivity of the power supply and water applied, to maintain the disinfectant disinfection ability accordingly, and to prevent unnecessary power consumption At the same time, to provide a sterilization and disinfection apparatus using a metal ion to maintain the metal ion production rate is mixed at a constant rate corresponding to the total amount of water.

In addition, the service life of the electrode plate, which is a material of metal ions, can be extended to reduce the cost of the electrode plate, to facilitate the disassembly and assembly of each component including the electrode plate, and to easily remove the oxide film formed on the electrode plate. The present invention also provides a sterilization and disinfection apparatus using metal ions and a method for easily generating and supplying metal ions.

It is connected to the gap adjusting portion 44, 46, 50, 54 is installed so as to slide along the guide member (58).

The configuration of the electrode plate gap adjusting unit 44, 46, 50, 54, as shown in Figure 5, is provided with a first motor 44 to provide a rotational force by the control unit 80, The motor shaft 46 of the first motor 44 is composed of a screw rod.

Then, as shown in Figs. 5 to 8B, at a predetermined position of the motor shaft 46, the pressure plate is provided to slide along the upper surface of one side of the chamber 32 in response to the selective rotation of the first motor (44). 50 is provided, and the rod-shaped piston 54 provided in parallel with the longitudinal direction of the motor shaft 46 is provided on the side wall of the pressure plate 50 to face each electrode part 42, respectively. The end of the piston 54 is connected to the electrode plate (38a) of each side slidably installed is configured to transmit the sliding movement force of the pressure plate (50).

Accordingly, as the first motor 44 is selectively driven through the controller 80, the pressure plate 50 connected to the motor shaft 46 performs a sliding motion by screwing, and each piston 54 is pressed on the pressure plate. The gap between the two opposite electrode plates 38a and 38b is adjusted by transmitting the sliding motion of the 50 to the corresponding one electrode plate 38a and sliding along the guide member 58.

8B, the pinion 65 is provided on the motor shaft 46b, and the rack 67 is slidably installed on the upper surface of the chamber 32 corresponding to the pinion 65. On this rack 67, a piston 54b having a pinion corresponding to each electrode portion is constituted by a screw rod, and each one side electrode plate 38a hinged by being driven forward and backward according to the driving of the rack 67. ) May be formed in a sliding configuration.

On the other hand, the scale removal part 60 is provided in the side predetermined position of the chamber 32, as shown to FIG. 6 and FIG.

The structure of the scale removing unit 60 is installed so as to be able to vertically move up and down between the respective electrode plates 38a and 38b so that the brush shaft 62 provided with the brush 64 is located. Pinions 66 corresponding to the fixed racks 68 are provided on the side portions positioned near both ends of the brush shaft 62.

In addition, both ends of the brush shaft 62 are rotatably mounted to the driving pulley 72 which is rotated by the second motor 70 and the timing belt 76 which is connected to and driven by the driven pulley 74.

Therefore, according to the above-described configuration of the scale removing unit 60, when the second motor 70 is driven by the controller 80, the timing of receiving the rotational force through the driving pulley 72 and the driven pulley 74 The belt 76 rotates, and the brush shaft 62 is rotated and supported by the timing belt 76 to move up and down, and the pinion 66 fixed to both sides of the brush shaft 62 corresponds. An oxide produced between the two electrode plates by rotating the brush 64 in contact with the opposite surfaces of the two electrode plates 38a and 38b positioned to provide rotational force in the process of moving up and down the rack 68. The film will be removed.

Meanwhile, as shown in FIG. 5, the both electrode plates 38a and 38b penetrate through the respective fixing members 40a and 40b slidably installed along the guide member 58 to supply power lines 18a and 18b. The lower end shape of the fixing members 40a and 40b is fixed by the transfer bolt 39 connected to each other, and is formed in a shape to cover a portion where the two electrode plates 38a and 38b face each other.

Therefore, the upper portion of the electrode plates 38a and 38b to which the transfer bolt 39 is fixed has a configuration in which the fixing force is always maintained in response to the consumption of the lower portion as the generation of metal ions is suppressed.

On the other hand, the electrode plate gap adjusting unit 44, 46, 50, 54, the scale removing unit 60 and the control unit 80 for controlling various peripheral configurations will be described in more detail with reference to Figure 8a.

The above-described control unit 80 is installed on the chamber 32 to measure the concentration of the metal ions contained in the water and the water level corresponding to the flow of water in accordance with the standard of the chamber 32 and the chamber 32 by measuring the overall water level Level sensor 36 for measuring the amount, conductivity sensor 84 for measuring the conductivity of flowing water, ion water supply flow rate sensor 86 for measuring the amount of ionized water supplied by the formation of metal ions and these various sensors 82 Switching unit 94 for controlling the power supply to the printer 88, the monitor 92, the telecommunication unit 90, and the electrode plates 38a, 38b for outputting the status signals applied from the controllers 36, 84, 86; Etc. are connected.

In the above-described configuration, the water flowing through the chamber 32 flows at a constant flow rate from the upstream layer to the downstream layer, wherein the level sensor 36 installed on the chamber 32 has the size of the chamber 32. The total amount of water is measured and detected in response to the flow rate of water, and the signal sensed by the level sensor 36 is applied to the controller 80.

This is to allow the oxide film produced by the electrode plates 38a and 38b to which the positive electrode is applied to be naturally removed by modulation.

The oxide film formed on the electrode plates 38a and 38b is partially removed by the polarity modulation of the electrodes of the electrode plates 38a and 38b, but the oxide film, that is, the scale is not removed. By 80, the scale removing unit 60 is driven to form a configuration that is removed.

Accordingly, both electrode plates 38a and 38b are reduced in thickness at a constant rate in response to the continuous driving of the sterilizing apparatus 30, thereby extending the service life thereof, and continuously generating the required metal ions.

Meanwhile, the controller 80 drives the electrode plate gap adjusting units 44, 46, 50, and 54 to form the metal ions normally in response to the change in the amount of current due to the decrease in thickness. , 38b) to compensate for the thickness reduction of the electrode plate 38a, 38b through the movement of the gap.

Periodically alternately apply the polarity of the electrode and the power supply electrode, and the bonding portion with the transfer bolt is covered by the fixing member to maintain the thickness, and the oxide film generated on the positive electrode is automatically removed. In addition to this, it is possible to easily disassemble and assemble the respective components including the electrode plate, and to easily remove the oxide film formed on the electrode plate, that is, the scale, by the scale removing unit.
