Description

METHOD OF CONSECUTIVELY GENERATING RESIDUAL CHLORINE}

The present invention relates to a method of continuously producing residual chlorine, and when continuous disinfection is required such as a humidifier, a contact lens washer or a food storage device, the residual chlorine, such as hypochlorous acid, which is harmless to humans and has high sterilizing power, is continuously It is about how it can be generated.

Recently, the interest in hygiene and cleanliness around the life is increasing, such as the removal of pathogens on the hands using a hand cleaner to prevent the infection of the disease due to the increase in health concern.

In addition, many pathogens are suspended in the air, but may remain in the water they encounter daily, so that the pathogen remaining in the water is inhaled by the human body, causing many diseases. For example, a humidifier, which is widely used to control humidity in an indoor space to an appropriate level, is contaminated in a short time, so that contaminated water is sprayed to cause a disease such as a respiratory disease to a user. Recently, reports have been issued that disinfectants used to disinfect humidifiers kill pathogens but are harmful to humans and cause lung disease.

Therefore, there is a great need for a method capable of sustaining sterilization in real time as compared with a method of adding a sterilizing agent in sterilizing water.

In order to solve the above problems, the present invention, when a continuous sterilization disinfection is required, such as a humidifier, contact lens cleaner or food storage device, the residual chlorine such as hypochlorous acid and the like is harmless to humans and has high sterilizing power. It aims to provide a way to do it.

Through this, by sterilizing with residual chlorine containing hypochlorous acid, which is harmless to the human body in various fields such as a humidifier, a food storage device and a contact lens washer, it is intended to prevent infection from various devices around the life using water.

In order to achieve the above object, the present invention provides a method for producing residual chlorine using an electrode immersed in a liquid containing chlorine, comprising the steps of: installing an electrode to be immersed in the liquid; Installing an ultrasonic oscillator in the liquid such that ultrasonic waves are delivered to the electrode; Generating residual chlorine in the liquid by applying a direct current to the electrode; An ultrasonic cleaning step of cleaning the surface of the electrode by applying ultrasonic waves generated by operating the ultrasonic oscillator to the electrode; It provides a method for producing residual chlorine comprising.

Through this, the chlorine-containing liquid can be continuously electrolyzed to continuously implement a disinfectant disinfection effect on the liquid continuously consumed.

In other words, if the current is continuously supplied to the electrode immersed in the chlorine-containing liquid, more residual chlorine may be generated by electrolysis, but as shown in FIG. Despite the slowing down and constant supply of current, the amount of residual chlorine is reduced until some time passes, and then increases again, but not enough to produce more than initially produced. Not only this, even if the electrolysis is performed while switching the direction of the current introduced into the electrode, it does not depart from the tendency shown in FIG.

However, according to the present invention, it was confirmed that the concentration of residual chlorine can be continuously increased by performing an ultrasonic cleaning process using an ultrasonic oscillator while applying a direct current to the electrode.

Therefore, although it was impossible to continuously generate residual chlorine in the past, the present invention enables the continuous generation of residual chlorine, and thus, a humidifier, a contact lens cleaner, and a sterile liquid which must be used continuously or maintained in a sterilized state. Applicable to the food storage device and method of the Republic of Korea Patent Publication No. 10-725353 Patent Designed by the applicant.

At this time, after the DC current is introduced into the electrode for a predetermined time, the supply of the current is stopped, the ultrasonic oscillator installed in the water is operated to clean the electrode, and the DC current is again introduced into the electrode. Residual chlorine may be produced during the time of application. At this time, the time for generating residual chlorine such as hypochlorous acid by supplying a current to the electrode is made for 20 seconds to 1000 seconds. This is because even if the current is supplied to the electrode for 1000 seconds or more, the problem of lowering the concentration of residual chlorine in the liquid is caused. The ultrasonic cleaning step is then performed for 1/20 to 1/3 hour of the current supply time. That is, the ultrasonic cleaning process is performed for approximately 10 to 50 seconds.

While electrolysis is performed by supplying a direct current to the electrode, a large number of fine bubbles are generated, thereby causing a flow moving upward by buoyancy of the bubble around the electrode. In spite of the bubbles and liquid flow generated around the electrode in this way, the ultrasonic cleaning at the same time during the electrolysis, the shorter the time to stop the electrolysis at the electrode, the more advantageous effect that can produce more residual chlorine Can be obtained. In this case, the ultrasonic cleaning may be performed continuously as with electrolysis, but may be performed intermittently at intervals of 5 to 10 minutes.

At this time, the electrode is formed with a plurality of electrode projections facing each other, the charge is concentrated on the electrode projections can be used to precisely control the concentration of residual chlorine while consuming less power.

As described above, the present invention provides a method for generating residual chlorine using an electrode immersed in a liquid containing chlorine, comprising the steps of: installing an electrode to be immersed in the liquid; Installing an ultrasonic oscillator in the liquid such that ultrasonic waves are delivered to the electrode; Generating residual chlorine in the liquid by applying a direct current to the electrode; An ultrasonic cleaning step of cleaning the surface of the electrode by applying ultrasonic waves generated by operating the ultrasonic oscillator to the electrode; Including, it provides a method of producing residual chlorine that can implement the sterilization disinfection effect steadily with respect to the liquid continuously consumed by the electrolysis of the liquid containing chlorine continuously.

Through this, the present invention continuously generates residual chlorine, such as hypochlorous acid, which is harmless to humans and has high sterilizing power, on the spot for a subject that requires continuous disinfection, such as a humidifier, a contact lens washer, or a food storage device, to immediately clean and sterilize. The advantage that it becomes possible to hold | maintain is acquired.

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

Method for producing residual chlorine according to an embodiment of the present invention comprises the steps of installing the electrode in a liquid containing chlorine; Installing an ultrasonic oscillator in the liquid such that ultrasonic waves are delivered to the electrode; Generating residual chlorine in the liquid by applying a direct current to the electrode; An ultrasonic cleaning step of cleaning the surface of the electrode by applying ultrasonic waves generated by operating the ultrasonic oscillator to the electrode; It is made to include.

To this end, as shown in FIG. 2, a container 110 containing a chlorine-containing liquid such as brine, an electrode 120 provided to be immersed in the liquid 40 contained in the container 110, and an electrode The device 100 is configured of an ultrasonic oscillator 130 for generating an ultrasonic wave in the vicinity of the 120.

Here, the electrode 120 may be formed with electrode protrusions 123a facing each other as shown in FIG. 3. As the electrode protrusions 123a are arranged so as to face each other, the electric charges supplied are concentrated on the electrode protrusions 123a, so that residual chlorine such as hypochlorous acid can be generated with little power.

In this case, although the electrode protrusion 123a may be formed integrally with the electrode 120 of the conductive material, the groove 123g is formed in the plate of the conductive material, and the unit protrusion 123u is inserted into the groove 123g. It can also comprise by connecting. As the electrode protrusions 123a are formed as the unit protrusions 123u as described above, the electrode protrusions 123a are formed of a material having excellent electrolysis performance, and thus electrolysis can be stably performed for a long time.

The electrode 120 is connected to the power supply unit 128 for supplying a DC current through the wiring 125 so that the current is periodically or continuously supplied for a predetermined time.

The ultrasonic oscillator 130 is installed on the inner wall of the container 110 and operates while the current is supplied to the electrode 120 or while the current supply to the electrode 120 is temporarily stopped, thereby generating ultrasonic waves to generate the electrode 120. Clean the surface. The ultrasonic oscillator 130 is connected to the power supply 138 outside the vessel 110 by the wiring 135 to generate ultrasonic waves intermittently or continuously to clean the surface of the electrode 120.

The method for generating residual chlorine using the apparatus 100 configured as described above operates the ultrasonic oscillator 130 intermittently or continuously while continuously applying a DC current to the electrode 120 to continuously generate electrolysis. The surface of the electrode 120 is cleaned by ultrasonic waves.

In the case of cleaning the surface of the electrode 120 by ultrasonic waves, there is an advantage that the concentration of residual chlorine generated in the liquid 40 can be continuously increased as shown in the experimental result shown in FIG. 4. FIG. 4 shows the result of measuring the concentration of residual chlorine by generating ultrasonic waves for about 15 seconds at intervals of about 100 seconds while keeping 100 mL of 0.9% concentration of brine in a container 110 and continuously applying a direct current of 90 mA.

In order to increase the concentration of residual chlorine in this manner, the supply of the DC current applied to the electrode 120 is not interrupted, and the surface of the electrode 120 is periodically cleaned by ultrasonic waves generated by the ultrasonic oscillator 130, thereby removing the residual chlorine. The amount of generation can be maximized. Meanwhile, according to another embodiment of the present invention, in order to increase the concentration of residual chlorine, the supply of DC current applied to the electrode 120 is stopped and the surface of the electrode 120 is cleaned by ultrasonic waves generated by the ultrasonic oscillator 130. After that, the current supply may be resumed and repeated.

In the case of operating as described above, when there is no ultrasonic cleaning, as the concentration of residual chlorine is lowered after about 5 to 10 minutes, as shown in FIG. 1, the use of sterile water continuously, for example, a humidifier and a lens It is difficult to use in a washing machine, a food storage device, a tap water purification plant and the like. However, since the residual chlorine is continuously generated according to the current supply by performing the ultrasonic cleaning as described above, it can be effectively applied to the use that requires the use of sterile water continuously.

On the other hand, in order to implement a similar operation as described above, when two or more electrodes are provided in a container, and one pair of two electrodes is operated, the other pair of electrodes is not operated, and when the operated pair is stopped. By acting on other pairs of electrodes, a similar behavior can be achieved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Although the above-described experimental results are taken as an example of a current of 90 mA, the tendency of FIG. 1 and FIG. 4 was confirmed for other current values of 60 mA, 120 mA, 250 mA, and 1A. In addition, although the experiment result mentioned above took the electrode 120 in which the electrode protrusion was formed as an example, the tendency of FIG. 1 and FIG. 4 was also confirmed also about the plate electrode and the grid type electrode which are electrodes of a different shape. Therefore, the structure of this invention can be applied without a restriction | limiting of a current value or an electrode shape.
