Description

Technical Field

[0001] The utility model relates to composite electrolysis equipment, belonging to the field of electrolysis. Background Art

[0002] At present, in the field of electrochemistry, electrolyzed water with oxidation potential is mainly strong acidic water or strong alkaline water. The pH of strong acidic water is below 2.7, and the pH of strong alkaline water is above 11. Under these pH conditions, bacteria and microorganisms cannot survive. However, strong acids and strong bases are corrosive and pose hidden dangers in the disinfection of objects.

[0003] The current mature technology has certain limitations in the production and application of oxidation potential water. Usually, salt is added to the existing tap water, and two kinds of water are produced through a special electrolysis device. One is acidic water [also called oxidation (acidification) potential water], which can be used as an environmentally friendly disinfectant, and the other is alkaline water, which is generally not used, but in special circumstances, it can be used to have a certain auxiliary therapeutic effect on certain diseases after dilution (refer to the efficacy of ionized water). The main characteristics of oxidation (acidification) potential water are broad bactericidal spectrum and rapid bactericidal effect; many studies at home and abroad have proved that acidic oxidation (acidification) potential water has a broad bactericidal spectrum, which can not only kill bacterial propagules and viruses, but also kill spores and other pathogenic microorganisms. The results of laboratory sterilization tests show that due to the characteristics of oxidation (acidification) potential water, it is increasingly being adopted by many countries, including Japan and the United States.

[0004] However, pickling oxidizing potential water contains a large amount of high-concentration free chlorine as a free chlorine water product, which has many safety issues.

[0005] Therefore, the aim is to achieve an effect equal to or better than that of existing products in neutral electrolyzed water, wherein the electrolyzed water is neutral, has no chlorine odor, has a strong bactericidal power, and is effectively used for sterilization in bathing rooms, and for the disinfection of atopic reactions, tinea pedis, burns, abscesses, wounds, etc. It can also be used for deodorization of humans and pets, improving bad breath, and can be used as a lotion and health drink, and has the effects of washing food or cultivating plants, etc. Moreover, these effects can be sustained for a long time, and it has the characteristics of both strong alkalinity and strong acidity, and can be used as functional water in a wide range of fields such as medical care, electronics industry, agriculture, and food industry.

[0006] At present, the main reasons that affect the generation of high concentration active ions by neutral water electrolysis are:

[0007] Since the electrolytic cell is located near the outlet of the current disinfection spray, and the space near the nozzle is generally narrow, the size of the electrolytic cell has certain limitations, and a large volume electrolytic cell cannot be used, which affects the efficiency of electrolysis;

[0008] Some motor equipment, due to application scenarios or some particularly small portable equipment, has its own power supply problem, so that the electrodes cannot reach the specified electrolysis voltage and current density, thus affecting the efficiency of electrolysis;

[0009] Another reason is that the electrolytic cell is close to the nozzle, which will affect the electrolysis time and make the electrolysis incomplete. In short, such a structural design will affect the efficiency of electrolysis and fail to reach a certain oxidation potential. Utility Model Content

[0010] In order to overcome the defects of the prior art, the utility model provides a composite electrolysis device. The technical solution of the utility model is:

[0011] A composite electrolysis device, comprising:

[0012] A water supply unit, used for providing water source;

[0013] An electrolysis unit, the electrolysis unit comprising at least two interconnected electrolysis cells, each electrolysis cell sequentially electrolyzing water;

[0014] A spray unit, used for spraying the electrolyzed water;

[0015] A power supply unit, providing power to the electrolysis unit;

[0016] Control panel for controlling the electrolysis unit and the injection unit.

[0017] The electrolytic unit includes a first electrolytic cell and a second electrolytic cell interconnected with the first electrolytic cell, the second electrolytic cell is not electrically connected to the first electrolytic cell, and the second electrolytic cell and the first electrolytic cell share the same power supply unit.

[0018] The electrolytic unit includes a first electrolytic cell and a second electrolytic cell interconnected with the first electrolytic cell, the second electrolytic cell is not electrically connected to the first electrolytic cell, and the second electrolytic cell and the first electrolytic cell are powered by separate power supply units.

[0019] The first electrolytic cell performs primary electrolysis on the incoming water, and the water after the primary electrolysis enters the second electrolytic cell for secondary electrolysis.

[0020] The injection unit includes an air pump, an atomizing nozzle and a water spray pipe. An injection pipe is installed at the air outlet of the air pump. One end of the water spray pipe is connected to the water outlet port of the second electrolytic cell, and the other end is connected to the injection pipe. The other end of the injection pipe extends into the atomizing nozzle.

[0021] The anode and cathode of the first electrolytic cell are conductive diamond or metal, and the metal is one of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0022] The anode of the second electrolytic cell is conductive diamond, and the cathode is metal, wherein the metal is one of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0023] A gap is formed between the first electrolytic tank and the second electrolytic tank, and water is electrolyzed at a preset interval under the control of the control panel.

[0024] The first electrolytic tank and the second electrolytic tank are arranged in a horizontal direction or a vertical direction as a whole.

[0025] An angle is formed between a line connecting the first electrolytic cell and the second electrolytic cell and a horizontal direction.

[0026] The utility model has the advantages that after being electrolyzed in the first electrolytic cell, the water is no longer raw water, but electrolyzed water containing hydrogen, hydroxyl radicals, ozone and oxygen.

[0027] Then, the negative pressure generated by the air pump is immediately used to introduce the electrolyzed water into the second electrolytic cell for electrolysis. Since the electrolyzed water is rich in bubbles, the water flow rate will decrease due to the water flow rate Q, so the water flow rate will naturally decrease. The decrease in water flow rate will correspondingly extend the electrolysis time and make the electrolysis more complete.

[0028] By setting at least two stages of electrolytic cells to electrolyze neutral tap water or commercially available mineral water (without Cl), active particle liquids with oxidizing power components such as hydroxyl free radicals or hydrogen peroxide can be stably generated. In particular, we know that hydroxyl free radicals have high oxidizing power. Hydroxyl free radicals are a very active oxidizing free radical. Using hydroxyl free radicals to treat organic matter has the characteristics of high treatment efficiency and no secondary pollution. Electrolyzed water with active ion components has the advantages of broad spectrum and high efficiency, non-toxicity and no side effects, no drug resistance, no residue, and low cost of use. It is a pure physical disinfection principle and the electrolysis raw materials have no chemical components added, mainly tap water, mineral water or pure water. It will not produce side effects and irritation to human skin, mucous membranes, respiratory tract, and eyes, and has no irritating taste.

[0029] Can be widely used in:

[0030] 1) Deodorization, disinfection and sterilization in elderly care facilities and hospitals; 2) Deodorization, disinfection and sterilization in hotels, restaurants, teahouses and canteens; 3) Deodorization, disinfection and sterilization in business and crowded gathering places; 4) Deodorization, disinfection and sterilization in restaurants; 5) Sterilization and disinfection in medical clinics; 6) Sterilization in the mouth of dentists and families; 7) Facial spray using the oxidative potential electrolyzed water of the utility model, using the spray, water penetrates from the pores and the stratum corneum of the skin.

[0034] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.

[0035] See also Figures 1 to 3 The utility model relates to a composite electrolysis device, comprising: a water supply unit for providing a water source; an electrolysis unit, the electrolysis unit comprising at least two interconnected electrolysis cells, each electrolysis cell electrolyzing water in turn; a spray unit for spraying the electrolyzed water; a power supply unit 7 for providing power to the electrolysis unit; and a control panel 4 for controlling the electrolysis unit and the spray unit. In this embodiment, the water supply unit can be a water tank or a water inlet pipe directly connected to the water source.

[0036] like Figure 1As shown, the electrolytic unit includes a first electrolytic cell 5 and a second electrolytic cell 3 interconnected with the first electrolytic cell 5. The second electrolytic cell 3 is not electrically connected to the first electrolytic cell 5. The second electrolytic cell 3 and the first electrolytic cell 5 share the same power supply unit, thereby ensuring the electrolytic stability of each electrolytic cell.

[0037] The electrolysis unit includes a first electrolytic cell 5 and a second electrolytic cell 3 interconnected with the first electrolytic cell 5. The second electrolytic cell 3 is not electrically connected to the first electrolytic cell 5, and the second electrolytic cell 3 and the first electrolytic cell 5 are powered by separate power supply units. The first power supply is connected to the first electrolytic cell, and the second power supply is connected to the second electrolytic cell, so that they can be controlled separately. For example, sometimes high oxidation potential electrolysis of water is not required, and only the second power supply needs to be connected, and the second electrolytic cell needs to be used for electrolysis. By driving the electrolytic cells separately with separate power supplies, the electrolysis voltage and current density can be increased, so that the electrolysis is more sufficient.

[0038] The first electrolytic cell performs primary electrolysis on the incoming water (water entering from a water tank or an inlet pipe), and the water after the primary electrolysis enters the second electrolytic cell for secondary electrolysis; the electrolysis efficiency is increased by performing two electrolysis steps, while avoiding the need for a separate transition container, thereby reducing the volume of the electrolysis device, so that miniaturized equipment can also achieve the effect of high oxidation potential.

[0039] The injection unit includes an air pump 2, an atomizing nozzle 1 and a water spray pipe. An injection pipe 11 is installed at the air outlet of the air pump 2. One end of the water spray pipe is connected to the water outlet port of the second electrolytic cell 3, and the other end is connected to the injection pipe 11. The other end of the injection pipe 11 extends into the atomizing nozzle 1.

[0040] The anode and cathode of the first electrolytic cell 5 are conductive diamond or metal, and the metal is one of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0041] The anode of the second electrolytic cell 3 is conductive diamond, and the cathode is metal, wherein the metal is one of ceramic, titanium, platinum, gold, titanium alloy, nickel, palladium, platinum-ruthenium alloy or stainless steel.

[0042] A gap is formed between the first electrolytic tank 5 and the second electrolytic tank 3 , and water is electrolyzed at a preset interval under the control of the control panel.

[0043] like Figure 2 As shown, the first electrolytic cell 5 and the second electrolytic cell 3 are arranged in a horizontal direction as a whole; Figure 3 As shown, the first electrolytic cell 5 and the second electrolytic cell 3 are arranged in a vertical direction as a whole.

[0044] like Figure 1 As shown, an angle is formed between the connecting line of the first electrolytic cell 5 and the second electrolytic cell 3 and the horizontal direction.

[0045] In the utility model, when the water in the water tank is electrolyzed, a reaction will occur on the electrodes to generate hydrogen and oxygen. The following is a detailed description:

[0046] At the cathode (negative electrode), the hydrogen ions in the water molecules gain electrons and become hydrogen gas.

[0047] This half reaction can be expressed as:

[0048] 4H++4e-→2H2↑.

[0049] At the anode (positive electrode), the hydroxide ions in the water molecules lose electrons. In the reaction at the anode, the water molecules lose their hydrogen atoms, and the remaining oxygen atoms combine to form hydroxyl radicals, ozone and oxygen. This half of the reaction can be expressed as;

[0050] 4OH-→O2↑+2H2O+4e-.

[0051] Therefore, after electrolysis in the first electrolytic cell, the water in the water tank is no longer raw water, but electrolyzed water containing hydrogen, hydroxyl radicals, ozone and oxygen.

[0052] Then immediately pump the water into the second electrolytic cell for electrolysis through an air pump. Since the electrolyzed water is rich in bubbles, the water flow rate will decrease due to the water flow rate Q, so the water flow rate will naturally decrease. The decrease in water flow rate will correspondingly extend the electrolysis time and make the electrolysis more complete.

[0053] The electrolysis efficiency is increased by performing the electrolysis twice, and the setting of a separate transition container is avoided, thereby reducing the volume of the electrolysis device, so that miniaturized equipment can also achieve the effect of high oxidation potential.

[0054] Specifically, the first electrolytic cell is located in the water tank of the electrolytic device. It can be placed at the bottom of the water tank in an optimal manner, or at other locations, but it is necessary to ensure an effective distance from the second electrolytic cell. If there is no water storage device, the first electrolytic cell can be located at the water inlet channel, and it is also necessary to ensure an effective distance from the second electrolytic cell. The second electrolytic cell is located at the outlet of the nozzle. The first electrolytic cell and the second electrolytic cell can be powered by the same power supply or different power supplies. The so-called effective distance is to ensure that the time for the water flow to pass through the first electrolytic cell and the second electrolytic cell is controlled within 1S to ensure the concentration of the electrolytic product of the first electrolytic cell, and it is not reduced and decomposed, and the proportion of active ions is still high. At any section in the pipeline or water storage container, the pressure comes from only one end, that is, the direction of the pressure is unidirectional. When the outlet in the pressure direction is closed (the valve is closed), the fluid in the pipe is in a prohibited state. Once the outlet is opened, its flow rate depends on the pressure in the pipeline.

[0055] For quantitative analysis, you can use a water flow model, install a pressure gauge, flow meter or measure the flow capacity. For pressurized pipe flow, it can also be calculated. The calculation steps are as follows:

[0056] 1. Calculate the specific resistance s of the pipeline. If it is an old cast iron pipe or an old steel pipe, the specific resistance of the pipeline can be calculated using the Shevelev formula s = 0.001736 / d^5.3 or s = 10.3n2 / d^5.33;

[0057] 2. Determine the difference in effective head at both ends of the pipeline H = P / (ρg). If there is a horizontal drop h (the starting end of the pipeline is h higher than the end), then H = P / (ρg) + h, where: H is in m; P: is the pressure difference at both ends of the pipeline (not the pressure of a certain section), P is in Pa;

[0058] 3. Calculate the flow rate Q: Q = (H / sL)^(1 / 2)

[0059] 4. Flow rate V = 4Q / (3.1416*d 2 ) Where: Q-flow rate, in m 3 / s is the unit;

[0060] H-the head difference between the beginning and the end of the pipeline, in meters;

[0061] L-The length of the pipeline from the beginning to the end, in meters.

[0062] 5. Calculate the flow rate and flow time: Flow rate is the volume of fluid passing through a certain point per unit time, usually expressed in meters per second (m / s). In fluid mechanics, time can be calculated using the following formula:

[0063] Time = volume / flow rate / area of ​​fluid passing through

[0064] Among them, the volume of fluid passing is the volume of fluid passing through a certain point per unit time, time is the time it takes for the fluid to pass, and area is the unit area passed by the fluid.

[0065] Example: The water flow volume of a water pipe is 0.01 cubic meters, the water flow rate is calculated to be 0.1 meters per second, the cross-sectional area of ​​the pipe is 0.01 square meters, and the length of the water pipe is 1 meter. Then the time for the water flow to transport water can be calculated as:

[0066] Time = 0.01 cubic meter / 0.1 / 0.01 = 10 seconds;

[0067] At this time, the relationship between water flow time and distance is that the water flows for 10 seconds to cover a distance of 1 meter. If the first electrolytic cell is set to electrolyze for 5 seconds, then the distance between the first electrolytic cell and the second electrolytic cell should be 0.1 meter.

[0068] When working, the start switch is turned on, the first electrolytic cell starts electrolysis, the electrolysis setting time is at least 5 seconds, preferably 5-20 seconds, and the electrolysis stops automatically. Then the second electrolytic cell can be manually started to start electrolysis, and the electrolytic spray uses an air pump or an ultrasonic instrument to spray the water mist electrolyzed water for use. If the first electrolytic cell and the second electrolytic cell are selected to work at the same time, it can be realized that after the button is pressed, electrolyzed water is continuously provided without interruption.

[0069] Automatic control can also be adopted, using a time relay to set the interval time between starting the first electrolytic cell and the second electrolytic cell to achieve automatic control.

[0070] Step 1: Add raw water into the water tank and set the electrolysis time of the first electrolytic cell, which can also be a fixed time;

[0071] Step 2: Connecting the first electrolytic cell to a power source to electrolyze the aqueous solution in the first electrolytic cell;

[0072] Step 3: After the first electrolytic cell electrolyzes for a set time, the second electrolytic cell is started to electrolyze;

[0073] Step 4: At this time, the first electrolytic cell can stop electrolysis or can also perform electrolysis synchronously;

[0074] Step 5: Spray out the electrolyzed water from the second electrolytic cell.

[0075] The electrolytic cell of the utility model is used to electrolyze water, so that it can be used immediately after it is made. Experiments have shown that the electrolysis time of the first electrolysis unit is at least 5 seconds from the time the power is turned on to the time water comes out of the nozzle, and the second electrolysis time is controlled to be between 5 and 20 seconds, plus an interval of 1 second, to ensure the oxidation potential value at the nozzle.

[0076] The verification of the concentration of active ions generated by electrolyzed water is explained by detecting the data of oxidation potential, because in the electrolysis reaction, the oxidation products such as HClO, O3, and hydroxyl free radicals have oxidation potential, and the inlet water in this scheme is commercially available mineral water and purified water, so the electrolysis product of this scheme does not contain hypochlorous acid. Secondly, this scheme is ready for use, and the entire electrolysis time is controlled within 10 to 41 seconds, and the time for electrolyzing water to generate high-concentration ozone is 2 to 4 minutes, so the main component of the product representing the oxidation potential of this scheme is hydroxyl free radicals.

[0077] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
