Description

Electro-analysised water capabilities and improved manufacturing equipment

The present invention relates to an apparatus for producing electrolytic water with improved functionality, and more particularly, injecting acidic chemicals into acidic water and alkaline chemicals into alkaline water in the process of decomposing acidic and alkaline water through electrolysis using seawater. It relates to an electrolytic water production apparatus that can automatically control the properties of the acidic and alkaline water finally derived by automatically injecting as needed.

As artificial cultivation of Haitai (Kim) aquaculture was possible and various aquaculture techniques were developed, stable mass production of seaweed was achieved. Accordingly, the algae, which were attached to the laver's lamellar, caused disease and degraded quality There is a problem that needs to be eliminated.

Efforts to remove algae from laver farms have continued for a long time. During 1977 to 1978, a sea food hunter in Chiba Prefecture, Japan, made several experiments to prevent the removal of laver and algae. It was found that the plant has an anti-blur effect, and this discovery was later developed as an acid treatment technology for seaweed farms. Later, the acid treatment technology in seaweed farms spread rapidly, and by the end of 1979, most of the seaweed farms in Japan used acid treatment agents. In addition, around 1980, as a result of experiments in fisheries test sites in Chiba and other prefectures, acid treatment agents were reported to be effective in removing diatoms, removing diatoms, and removing bacteria and adherent bacteria.

This method has been introduced in Korea and is now widely used. However, while acid treatments have an excellent effect on the removal of seaweeds, if they are dumped into the ocean after use, they can adversely affect marine ecosystems. It is prescribed to recover and neutralize with a neutralizing agent at pH7.8 ~ 8.3 for disposal. In addition, as an acid treatment agent, only an organic acid is prescribed in consideration of the environment, and an inorganic acid is strictly prohibited because it is harmful to a human body.

However, since organic acids are expensive, it is often the case to use inorganic acids to avoid surveillance. Therefore, in Korea, the notice on the use of acid treatment agent for seaweed farms has been decided and is strictly managed by the acid treatment council and guidance committee.

As the method of using the acid treatment agent, the immersion type method of immersing the Haitai net in an acidic solution for 5-10 minutes when the length of the laver of the seaweed is 2 ~ 3cm is most widely used. In some cases, a method using a power sprayer or the like may be used.

However, this acid treatment agent is not only expensive, but also has a disadvantage in that it is not economical because the neutralizer for acid treatment must be prepared separately.

FIG. 1 is a view for explaining the principle of general electrolysis. Referring to the drawings, first, a pair of pole plates 3 are installed in an electrolytic cell 1 in a state where water is filled in the electrolytic cell 1. The pair of pole plates 3 are connected by a separate power source 5 to have polarities of the positive and negative poles, respectively, with hydroxide ions (OH-) on the positive pole plates and hydrogen ions (H +) on the negative pole plates. ) Are gathered.

As such, in order to electrolyze water, the electrode plate 1 is installed inside the electrolytic cell 1 to increase the voltage between the electrode plates 3 so that the water is ionized and the current gradually flows. At two to three volts the current flow becomes stronger. At this time, the part where the current flow becomes strong is called the decomposition voltage, and the current slowly rises up to the decomposition voltage of 2 to 3 volts and then increases linearly and rapidly.

In addition, there are several methods of electrolysis of water. There are a method of electrolysis in a region below the decomposition voltage and a method of electrolysis above the decomposition voltage. In addition, there may be a case where a diaphragm is provided between the two electrodes and not. .

Among them, the electrolytic cell 1 in which the diaphragm 7 is installed is shown in FIG. 2, and the diaphragm 7 serves to block the flow of water while facilitating the flow of electric current flowing between the positive electrode plates 3. In other words, the diaphragm 7 serves to pass only an electric current without passing water, thereby preventing the ions generated in the water from being mixed by external factors such as shaking.

Thus, the diaphragm 7 blocks the mixing of the materials produced at each electrode, thereby separating the water into acidic and alkaline water.

However, in the prior art, the acidic water and the alkaline water are electrically separated after the introduction of seawater. In this case, the characteristics cannot be controlled according to the required use of the acidic water and the alkaline water.

The present invention uses acidic water generated by electrolysis of seawater (sea water) which can be easily obtained without using an acid treatment agent treated separately in aquaculture farms as an acid treatment agent, and before electrolysis is explained before explaining the configuration of the present invention. Briefly, the principle of To explain the electrolysis process in detail, if both electrodes are electrically connected to each other in the electrolysis below the decomposition voltage, H + is attracted to the cathode to be reduced to hydrogen, and OH- is attracted to the anode but not oxidized and also generates oxygen. I don't even let you. Thus, while H + in the electrolyte is consumed but OH- is accumulated without decomposition, the electrolyte naturally turns into alkali. In the electrolysis above the decomposition voltage, a diaphragm or an ion exchange membrane is used. When an electrolyte such as NaCl or KCl is added to the electrolyzed water, an electrolyte having a higher tendency of ionization than water is electrolyzed and Na +, K + Cations such as are collected in the negative electrode plate and anions such as Cl- are collected in the positive electrode plate. Therefore, alkaline water containing NaOH, KOH, etc. is produced on the cathode side, and acidic water containing HCl, etc. is produced on the anode side.

In particular, since seawater contains a large amount of NaCl, when electrolyzing seawater generates an acid such as HCl on the positive electrode plate, acidic water is generated around the cathode plate, and alkali water, such as NaOH, is generated on the negative electrode plate. Will be generated.

One embodiment applying the principle of the electrolysis to the present invention is shown in Figure 3, the electrolytic water production apparatus according to the present invention is designed to produce a large amount of electrolytic water while having a pipe-like structure. Referring to the drawings, the electrolytic water manufacturing apparatus according to an embodiment of the present invention includes a seawater pipe 100 pipe in the form of a pipe for passing seawater inside, and provides a positive electrode and a negative electrode in the seawater pipe 100 A pair of pole plates 120 and 140 are installed. At this time, the electrode plates 120 and 140 electrolyze the seawater passing through the seawater pipe 100. In particular, the cathode plate 120 electrolytically decomposes NaCl contained in a large amount in the seawater. In addition, the positive electrode plate 140 generates acidic water containing chlorine and HCl.

In addition, a predetermined diaphragm 160 is provided between the anode plates 120 and 140 so as to bisect the seawater pipe 100. As described above, the diaphragm 160 prevents mixing of alkaline and acidic water generated by electrolysis with each other, thereby promoting ionization by electrolysis. When the chlorine and acidic water generated in this way is sprayed on the area where the miscellaneous water is generated in the seaweed farm, the first aid is controlled by the disinfecting power of chlorine, and the second operation is controlled by the sterilizing power of strong acidic water.

In addition, the acidic water used to relieve the miscellaneous goods should be neutralized since it may be contaminated with seawater or harmful to the human body if left as it is, in the present invention, without using a separate neutralizing agent to neutralize the acidic water, acidic water production Alkaline water generated in the process is used. As such, when the acidic water and the alkaline water generated by electrolysis are mixed and neutralized again, the ions are reduced to each other and become seawater again, so that they are not harmful to the environment and the human body.

In the above embodiment, the electrode plates 120 and 140 may be separately installed in the seawater pipe 100 or may be formed to be part of the seawater pipe 100. In addition, in order to generate more electrolytic water at the same electric power, the larger the area of the pole plate in contact with the sea surface, the better, and therefore, the area of the pole plates 120 and 140 is advantageous. In addition, in order to make the concentrations of the electrolyzed acidic and alkaline water constant without being irregular, it is preferable that the surface area and the spacing of the electrode plates 120 and 140 are designed to be constant so that the seawater in the seawater pipe 100 is uniformly electrolyzed. Do.

In addition, it is preferable that the electrode plates 120 and 140 used in the present invention are metallic, and in particular, a material which does not dissolve or corrode by seawater is more preferable, and an insoluble metal such as titanium or stainless steel is most preferable.

In the large-capacity electrolytic water production apparatus, as illustrated in the drawing, an electrolytic cell 200 for electrolyzing seawater passing through the interior is divided by a plurality of electrode plates 220, 230, and 240 at regular intervals. In addition, the diaphragm 260 which bisects the division area of the electrolytic cell 100 divided by the pole plate 220 is provided between each pole plate 220. The electrolyzer 200 is also connected to an introduction tube 300 for supplying seawater to each of the regions divided by the electrode plate 220 and the diaphragm 260, and also the acidic and alkaline water electrolyzed in the electrolyzer 200. Leading pipes 320 and 340 for providing the outside to each are connected.

The introduction pipe 300 supplies seawater to each area divided by the electrode plate 220 and the diaphragm 260 of the electrolytic cell 200 by introducing seawater through an external pump, and the seawater introduced into the electrolytic cell 200. Are separated by the electrode plates 220 and 230 and the diaphragm 260 so as not to be mixed with each other.

However, since only ions may move through the diaphragm 260 during electrolysis, electrolysis in the electrolytic cell 200 occurs independently for each region between one electrode plate and another adjacent electrode plate.

At this time, the electrode plate 220 divides the electrolytic cell 200 at regular intervals, and the electrode from the power source 280 is connected to the electrode plates corresponding to both ends of the electrolytic cell 200. When power is supplied from the power supply 280 to the pole plates 220 and 240 at both ends of the electrolytic cell 200, electrolysis occurs through all the pole plates by the flow of ions. In detail, if the positive electrode is applied to the end electrode plate 220, negative ions are collected in the anode plate 220 through the diaphragm 260 between the anode plate 220 and the adjacent electrode plate 230. In the region between the diaphragm and the membrane 260, acidic water containing a component such as HCl is generated, and cations remain near the adjacent electrode plate 230, so that alkaline water containing a component such as NaOH is generated in this region. In addition, the adjacent electrode plate 230 also has a positive electrode because the negative ions moved to the end-side electrode plate 220, so that the electrolysis as previously occurs by another adjacent electrode plate.

At this time, the electrode plate 220 divides the electrolytic cell 200 at regular intervals, and the electrode from the power source 280 is connected to the electrode plates corresponding to both ends of the electrolytic cell 200. When power is supplied from the power supply 280 to the pole plates 220 and 240 at both ends of the electrolytic cell 200, electrolysis occurs through all the pole plates by the flow of ions. In detail, if the positive electrode is applied to the end electrode plate 220, negative ions are collected in the anode plate 220 through the diaphragm 260 between the anode plate 220 and the adjacent electrode plate 230. In the region between the diaphragm and the membrane 260, acidic water containing a component such as HCl is generated, and cations remain near the adjacent electrode plate 230, so that alkaline water containing a component such as NaOH is generated in this region. In addition, the adjacent electrode plate 230 also has a positive electrode because the negative ions moved to the end-side electrode plate 220, so that the electrolysis as previously occurs by another adjacent electrode plate.

Thus, the electrolyzed seawater generates acidic water in the region of the positive electrode plate side and alkaline water in the region of the negative electrode plate side based on each of the diaphragms 260. And are separated and discharged by the alkaline water derivation pipe 340, respectively. By continuously connecting the pole plate 220 and the diaphragm 260 in this way, a large amount of electrolytic water can be generated with the same power, and in particular, the amount of the electrolyzed water is determined according to the area and the number of the pole plate 220.

At this time, as shown in Figure 4 as the main technical gist of the present invention, the first injector 800 and the second injector 810 that can actively inject acidic drugs and alkaline drugs into the induction pipe 320, 340 It is composed. The first injector injects the acidic chemicals and the second injector injects the alkaline chemicals, which are controlled by the control means to determine the injection amount and inject.

The first injector and the second injector are implemented through an electrically operated solenoid valve and a compressor, which are controlled by the control means as mentioned above. After controlling the seawater by controlling the seawater electrically by controlling the seawater electrically, it is possible to control the injector to control the characteristics of each of the resulting acidic and alkaline water.

5 is an equivalent circuit diagram of an electrolytic water production apparatus according to the present invention, Figure 6 is a configuration diagram showing the controller of the electrolytic water production apparatus according to the present invention in detail.

The basic principle of this structure is the principle of voltage distribution, which can be represented by an equivalent circuit as shown in FIG. In the figure, the electrode plate 220 is represented by a dot, R denotes a resistance value between the electrode plates, and it is the current that determines the electrolytic concentration. Therefore, such a structure is a multi-layer structure using the principle of high capacity and high voltage distribution by breaking away from the electrolytic water separation structure using only a pair of pole plates.

The capacitor 290 is a capacitor commonly used for the stability of the power supply 280. Condenser 390 may be used for power supply stabilization between each pole plate 220. An equivalent circuit diagram showing an electrolytic water device to which such a capacitor is added is shown. In fact, when electrolyzing seawater, the power supply between the pole plates becomes unstable as it moves away from both ends due to foreign matter in the seawater. Therefore, by providing a capacitor 390 between each pole plate 220, the instability of the power supply can be significantly solved.

Looking at the control portion, the electrolytic water production apparatus is a pump 400 for introducing seawater using the power of the power supply unit 540 and the power supply unit 540, and the acidic water by electrolyzing the seawater introduced by the pump 400 And an electrolyzer 500 for generating alkaline water, and a power supply 540 to adjust the amount of current for electrolyzing seawater in the electrolyzer 500 and also to control the amount of seawater flowing into the electrolyzer 500. Controller 700 to control the output of the pump 400 in order to.

Here, the electrolyzer 500 is the same as the above-described embodiment, and although not shown, the introduction pipe 300 is installed between the pump 400 and the electrolyzer 500, and the acid that is electrolyzed from the electrolyzer 500. Similar drawpipes 580 and 600 are arranged to provide water and alkaline water.

6 illustrates an internal configuration of the controller 700. As shown in the drawing, the controller 700 includes sensors 720 and 740 for sensing power of the power supply 540, and a plurality of keys. Compare the power value detected by the key input unit 840 and the sensors 720 and 740 to input certain information from the outside with the set value input through the input unit 840, and adjust the output of the power according to the comparison result. The microprocessor 820 and a display 860 for externally displaying the power values sensed by the sensors 720 and 740 and the setting values input through the input unit 840.

In addition, the controller 700 may further include an A / D converter 870 for converting the analog values detected by the sensors 720 and 740 into digital values, wherein the converted digital values are microprocessors 820. Will be entered.

The controller 700 configured as above compares the power values detected by the sensors 720 and 740 with a setting value input by the user through the key input unit 840, and increases the output when the power value is lower than the setting value. If it is higher, the output is lowered to control the power value closer to the set value, and if an unexpected value is detected, the system can be stopped immediately.

As described so far, the electrolytic water production apparatus according to the present invention is used as a substitute for the organic acid used to remove large amounts of seaweed by producing a large amount of electrolytic water, that is, acidic and alkaline water using an electric method that has not been applied so far I would like to.

Algae removal using strong acidity has already been found to be effective, but there were many problems in cost and capacity to make strong acidity, but the present invention completely solved this problem.

When the electrode plate and the diaphragm are manufactured in multiple layers as in the electrolytic water production apparatus according to the present invention, the structure is relatively simple and at the same time, a large amount of electrolytic water can be produced. If about 20 kw of electric power can be supplied, the electrolyzed water production apparatus of the present invention can generate more than 300 liters of electrolyzed water per minute.

In addition, the power supply device is based on the 220V 60Hz general commercial power supply, but depending on the situation and conditions, the power capacity can be changed as much, especially when using three-phase 220V three times the electrolytic water production capacity than the single phase You can increase it.

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 exemplary embodiments. On the contrary, those skilled in the art will appreciate that many modifications and variations of the present invention are possible without departing from the spirit and scope of the appended claims. And all such modifications and changes as fall within the scope of the present invention are therefore to be regarded as being within the scope of the present invention.
