Description

Technical Field

[0001] The invention relates to a disinfection and sterilization technology, in particular to a device for generating disinfectant water by using diamond film electrolysis. Background Art

[0002] Ozone is a strong oxidant, and the sterilization process is a biochemical oxidation reaction. Ozone disinfection has the following three forms: 1. Ozone can oxidize and decompose the enzymes needed to degrade glucose inside bacteria, causing the tricarboxylic acid cycle (TCA cycle) to be unable to proceed, resulting in the inability to supply ATP required for cell life activities, causing the bacteria to be inactivated and die; 2. Directly act on bacteria and viruses, destroying their organelles and DNA and RNA, causing the metabolism of bacteria to be damaged and leading to bacterial death; 3. Penetrating cell membrane tissue, invading cells, acting on the lipoproteins of the outer membrane and the lipopolysaccharides inside, causing the bacteria to undergo permeability distortion and dissolve and die.

[0003] Ozone is generally prepared by high-voltage corona discharge and electrochemical methods. The high-voltage corona discharge method has high energy consumption and low efficiency, while the electrochemical method has low energy consumption and high efficiency.

[0004] The electrochemical method is a technology that uses special electrode materials to electrolyze water to produce ozone and hydroxyl radicals and other strong disinfectants. It is also the most advanced means of producing ozone. The core of the electrochemical method is the electrode material. Diamond film electrode is the anode material with the highest efficiency and lowest energy consumption for producing ozone because of its chemical inertness, long life, low loss and non-toxicity.

[0005] The existing electrochemical method of ozone water electrolysis uses titanium sheets as cathodes and anodes. A wet ion membrane is required between the titanium sheet and the diamond electrolytic sheet as a medium to enhance the conductivity. However, if the module is not working for a long time, the ion membrane will dry out, resulting in functional failure. Summary of the invention

[0006] The technical problem to be solved by the present invention is to avoid the deficiencies of the prior art and propose a diamond membrane disinfection module which prevents the ion membrane from drying out and ensures that the product can still effectively electrolyze and generate ozone water when it is not used for a long time.

[0007] The technical solution adopted by the present invention to solve the technical problem is: Provided is a diamond membrane module for generating ozone water by electrolysis, comprising a water inlet shell, a water outlet shell, an ozone generating unit and a diaphragm reaction chamber located between the water inlet shell and the water outlet shell, wherein the water inlet shell, the water outlet shell and the diaphragm reaction chamber are arranged vertically, the water inlet of the water inlet shell and the water outlet of the water outlet shell are both arranged horizontally, the ozone generating unit is arranged in the diaphragm reaction chamber, and the ozone generating unit comprises an anode titanium sheet, a diamond membrane electrode sheet, an ion membrane and a cathode titanium sheet which are arranged in sequence; the water outlet of the diaphragm reaction chamber is located higher than the top of the ion membrane.

[0008] Further: A pit is provided on one side of the membrane reaction chamber, the ozone generating unit is located in the pit, and the water outlet of the membrane reaction chamber is located at the highest position of the pit.

[0009] There is one diaphragm reaction chamber, and the concave surface of the diaphragm reaction chamber and the inner cavity of the water inlet shell form a water storage cavity.

[0010] There are two or more diaphragm reaction chambers, each of which is vertically stacked between the water inlet shell and the water outlet shell. The concave surface of the first diaphragm reaction chamber forms a water storage chamber with the inner cavity of the water inlet shell, and the concave surfaces of other diaphragm reaction chambers form a water storage chamber with the other surface of the diaphragm reaction chamber adjacent to the front thereof.

[0011] The anode titanium sheet, the diamond membrane electrode sheet, the ion membrane and the cathode titanium sheet are provided with through holes.

[0012] There is a graphene conductive adhesive coating between the cathode titanium sheet and the ion membrane, and there is a graphene conductive adhesive coating between the anode titanium sheet and the diamond membrane electrode sheet.

[0013] It also includes a control circuit board for adjusting the working voltage and current of the module according to different water qualities so as to keep the output power constant.

[0014] The water inlet shell, the water outlet shell and the top of the diaphragm reaction chamber together form a groove, and the control circuit board is arranged in the groove.

[0015] The outer sides of the water inlet shell and the water outlet shell are both provided with pressing blocks, and the pressing blocks, the water inlet shell, the diaphragm reaction chamber and the water outlet shell are fixed into one body by screws and nuts.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The water storage cavity formed inside the module can keep the ion membrane immersed in water, keep the ion membrane moist for a long time, prevent the ion membrane from drying out, and ensure that the product is still effective when not in use for a long time.

[0017] The ozone concentration in the generated ozone water does not change with the water quality, and can meet the ozone concentration required for disinfection effect in ozone water when the water flow is large. Avoid the concentration of ozone water being affected by the water flow, which will cause the ozone content produced by the module to decrease when the water flow is large, and fail to achieve the disinfection effect; and avoid the ozone content in ozone water changing with the water quality, so that the ozone concentration is unstable and cannot be accurately applied in the scene.

Implementation

[0020] Now, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2As shown, a diamond membrane module for electrolyzing ozone water comprises a water outlet shell 3, a water inlet shell 5, a membrane reaction chamber 4, a control circuit board 6 and an ozone generating unit, wherein the ozone generating unit comprises a cathode titanium sheet 9, an ion membrane 10, a diamond membrane electrode sheet 11 and an anode titanium sheet 13.

[0022] like Figure 6 and Fig. 9 As shown, the membrane reaction chamber 4 is arranged between the water inlet shell and the water outlet shell, the water inlet shell 5, the water outlet shell 3 and the membrane reaction chamber 4 are arranged vertically, and the water inlet channel 51 of the water inlet shell 5 and the water outlet channel 31 of the water outlet shell 3 are both arranged horizontally. Figure 2 As shown, the ozone generating unit is arranged in the membrane reaction chamber 6, and the anode titanium sheet 13, the diamond membrane electrode sheet 11, the ion membrane 10 and the cathode titanium sheet 9 are placed in sequence from the inside to the outside. The water outlet 41 of the membrane reaction chamber 4 is located higher than the top of the ion membrane 10 so that the water level of the water storage chamber in the module is higher than the top of the ion membrane 10.

[0023] like Figure 3 and Figure 4 As shown, a pit 42 is provided on one side of the diaphragm reaction chamber 4, the ozone generating unit is located in the pit 42, and the water outlet 41 of the diaphragm reaction chamber 4 is located at the highest position of the pit.

[0024] like Figure 5 In the embodiment shown, a membrane reaction chamber 4 is provided. Figure 6 As shown, the pit 42 of the membrane reaction chamber and the inner cavity of the water inlet shell form a water storage cavity. The water inlet of the water inlet shell and the water outlet of the water outlet shell are both located in the center of each other and at the middle height position of the water storage cavity.

[0025] like Figure 7 and Figure 8 In the illustrated embodiment, two or more diaphragm reaction chambers are provided, each diaphragm reaction chamber 4 is vertically stacked between the water inlet shell 5 and the water outlet shell 3, the concave surface (i.e., the front) of the first diaphragm reaction chamber forms a water storage chamber with the inner cavity of the water inlet shell, and the concave surfaces of other diaphragm reaction chambers form a water storage chamber with the other surface (i.e., the rear) of the diaphragm reaction chamber adjacent to the front thereof.

[0026] like Figure 2As shown, in some embodiments, there is a graphene conductive glue coating 14 between the cathode titanium sheet 9 and the ion membrane 10, and there is a graphene conductive glue coating between the anode titanium sheet 13 and the diamond membrane electrode sheet 11. Since precipitates are generated during the electrolysis process, a barrier layer is generated between the ion membrane and the cathode titanium sheet, resulting in increased ion channel resistance, reduced conductivity, and a sharp drop in module performance. For this reason, graphene conductive glue is sprayed between the cathode titanium sheet and the ion membrane to fill the gap between the two and increase the service life of the module. Graphene conductive glue is sprayed between the anode titanium sheet and the diamond membrane electrode sheet to effectively increase the electrical contact between the diamond electrode sheet and the anode titanium sheet, prevent the generation of insulating substances between them, and thus enhance the overall conductivity.

[0027] Through holes are arranged on the anode titanium sheet 13, the diamond membrane electrode sheet 11, the ion membrane 10 and the cathode titanium sheet 9. The diamond membrane electrode sheet is easy to generate large ozone bubbles during the electrolysis process, which are difficult to dissolve in water and may cause a large amount of ozone to volatilize. The large ozone bubbles are cut into countless tiny bubbles by punching holes in the anode titanium sheet, the cathode titanium sheet and the ion membrane, which can increase the ozone dissolution rate.

[0028] The left and right sides of the membrane reaction chamber 4 are a water outlet shell 3 and a water inlet shell 5 . The water outlet shell 3 is provided with a water outlet pipe joint, and the water inlet shell 5 is provided with a water inlet pipe joint.

[0029] The water inlet shell 5 and the water outlet shell 3 are both provided with a pressing block 2, and the pressing block 2, the water inlet shell 5, the membrane reaction chamber 4 and the water outlet shell 5 are fixed together by stainless steel screws 1 and nuts 15. In this embodiment, the pressing block 2 is made of stainless steel.

[0030] like Fig.10 and Fig.11 In the illustrated embodiment, a control circuit board 6 is also included for adjusting the working voltage and current of the module according to different water qualities so that the output power is constant. The water inlet shell 5, the water outlet shell 3 and the top of the membrane reaction chamber 4 are jointly formed with a groove 16, and the control circuit board 6 is arranged in the groove 16. The existing diamond membrane module driven by a fixed voltage has an ozone content that changes with the change of water quality, outputs different ozone concentrations, and sometimes has no disinfection effect; while the diamond membrane module of the present invention has a constant power control circuit board, which automatically adjusts the working voltage and current according to different water qualities, maintains operation at a stable power, and controls the ozone concentration of the ozone water generated by the module in real time and stably.

[0031] An example of a method for adjusting the working voltage and current of the module to make the output power constant according to different water qualities is as follows: When setting a diaphragm reaction chamber, the input voltage / current is 3.7V / 2A, and the output constant power is set to 5W. The circuit works in BOOST mode. When the load current is greater than or equal to 0.4A, the MCU of the control circuit board adjusts the boost switch duty cycle and the output voltage according to the increase in the detected load current, so that the output power is constant at 5W, thereby achieving the output constant power state.

[0032] When three diaphragm reaction chambers are set, the input voltage / current is 15V / 2A, and the output constant power is set to 15W. The circuit works in BUCK mode. When the load current is less than or equal to 1A, the circuit works in linear mode. When the load current is greater than 1A, the circuit works in BUCK mode. The MCU of the control circuit board adjusts the duty cycle of the buck switch according to the increase in the detected load current, and the output voltage drops, so that the output power is constant at 15W, thereby achieving the output constant power state.

[0033] A diamond film module for electrolyzing ozone water, as shown in Example 1 Figure 5 As shown, it includes PM3X55 stainless steel screws 1, stainless steel blocks 2, water outlet shell 3, a diaphragm reaction chamber 4, water inlet shell 5, constant power control circuit board 6, M3 stainless steel nuts 7, PM2.5*7 titanium screws 8, M2.5 titanium nuts 12, nuts 15 and potting glue, etc. An ozone generating unit is arranged in the diaphragm reaction chamber 4, and the ozone generating unit includes a cathode titanium sheet 9, an ion membrane 10, a diamond membrane electrode sheet 11, an anode titanium sheet 13 and a graphene conductive glue 14.

[0034] The module installation process of this embodiment is as follows: The first step is to assemble the ozone generating unit into the membrane reaction chamber 4. First install the anode titanium sheet 13, then spray the graphene conductive glue 14, then install the diamond membrane electrode sheet 11 and the ion membrane 10 in sequence, then spray the graphene conductive glue 14 on the cathode titanium sheet 9, and finally install the cathode titanium sheet 9, and use two titanium screws 8 and titanium nuts 12 to lock the above components in the pit of the membrane reaction chamber 4.

[0035] The second step is to fix the diaphragm reaction chamber 4 in the internal space formed by the water inlet shell and the water outlet shell. The diaphragm reaction chamber 4 equipped with the ozone generating unit is installed in the internal space formed by the water inlet shell 5 and the water outlet shell 3, and then stainless steel pressing blocks 2 are added on both sides, and the diaphragm reaction chamber, the water inlet shell, the water outlet shell and the pressing blocks are fixed together by 6 stainless steel screws 1 and nuts 7.

[0036] The third step is to install the control circuit board 6 in the top groove of the module and then seal it with potting glue.

[0037] In the fourth step, water pipe joints 15 are provided on the water inlet shell 5 and the water outlet shell 3 .

[0038] In this embodiment, a diaphragm reaction chamber is provided, and the pit of the diaphragm reaction chamber and the inner cavity of the water inlet shell form a water storage chamber.

[0039] like Figure 6 As shown, water flows in from the water inlet 51 in the middle of the water inlet shell 5, flows out from the water outlet 31 in the middle of the water outlet shell 3 through the water outlet 41 on the top of the diaphragm reaction chamber, and water accumulates in the water storage chamber, which can keep the ion membrane immersed in water for a long time. The wet ion membrane is used as a medium between the anode titanium sheet, the cathode titanium sheet and the diamond electrolytic sheet, which can enhance the conductive performance and prevent the ion membrane from drying out after the module does not work for a long time, thereby causing functional failure.

[0040] Through the above technical solution, the module of this embodiment can ensure that the ozone concentration in water is greater than 1ppm when the water flow rate reaches 1000ml / min.

[0042] This embodiment is basically the same as the first embodiment, except that there are two membrane reaction chambers stacked in this embodiment, the purpose of which is to ensure the ozone content in the water when the water flow rate is increased.

[0043] Two diaphragm reaction chambers are overlapped, with water inlet shell 5 and water outlet shell 3 on both sides, two stainless steel pressing blocks 2 are added, and then the diaphragm reaction chamber, water inlet shell, water outlet shell and pressing blocks are fixed into one by 6 stainless steel screws 1 and nuts 7.

[0044] The constant power control circuit board 6 is installed in the top grooves of the two diaphragm reaction chambers and is sealed on the surface with potting glue.

[0045] In this embodiment, there are two diaphragm reaction chambers, which are vertically stacked between the water inlet shell and the water outlet shell. The concave surface of the first diaphragm reaction chamber and the inner cavity of the water inlet shell form a first water storage chamber, and the concave surface of the second diaphragm reaction chamber and the other surface of the first diaphragm reaction chamber form a second water storage chamber. Water flows into the first water storage chamber from the middle of the water inlet shell 5, flows into the second water storage chamber through the top of the first diaphragm reaction chamber, flows out from the top of the second diaphragm reaction chamber, and finally flows out through the middle of the water outlet shell 3. Water accumulates in the inner cavities of the two water storage chambers, which can keep the ion membrane immersed in water for a long time. The wet ion membrane is used as a medium between the anode titanium sheet and the cathode titanium sheet and the diamond electrolytic sheet, which can enhance the conductive performance and prevent the ion membrane from drying out after the module does not work for a long time, thereby causing functional failure.

[0046] Through the above technical solution, the module of this embodiment can ensure that the ozone concentration in the water is greater than 1ppm when the water flow rate can reach 2000ml / min.

[0047] A diamond film module for electrolyzing ozone water, as shown in Example 3 Figure 8 As shown, it includes PM3X55 stainless steel screws 1, stainless steel pressing blocks 2, water outlet shells 3, three diaphragm reaction chambers 4, water inlet shells 5, constant power PCB board 6, M3 stainless steel nuts 7, PM2.5*7 titanium screws 8, M2.5 titanium nuts 12, nuts 15 and potting glue, etc. Each diaphragm reaction chamber 4 is equipped with an ozone generating unit.

[0048] This embodiment is basically the same as the first embodiment, except that there are three membrane reaction chambers arranged in a stacked manner in this embodiment, the purpose of which is to ensure the ozone content in the water when the water flow rate is increased.

[0049] Three diaphragm reaction chambers are overlapped, with water inlet shell 5 and water outlet shell 3 on both sides, two stainless steel pressing blocks 2 are added, and then the diaphragm reaction chamber, water inlet shell, water outlet shell and pressing blocks are fixed into one by six stainless steel locking screws 1 and nuts 7.

[0050] In this embodiment, there are three diaphragm reaction chambers, which are vertically stacked between the water inlet shell and the water outlet shell. The concave surface of the first diaphragm reaction chamber and the inner cavity of the water inlet shell form a first water storage chamber, the concave surface of the second diaphragm reaction chamber and the other surface of the first diaphragm reaction chamber form a second water storage chamber, and the concave surface of the third diaphragm reaction chamber and the other surface of the second diaphragm reaction chamber form a third water storage chamber. Fig. 9As shown, water flows from the middle of the water inlet shell 5 into the first water storage chamber, flows into the second water storage chamber through the top of the first diaphragm reaction chamber, and then flows into the third water storage chamber from the top of the second diaphragm reaction chamber, and finally flows out from the top of the third diaphragm reaction chamber and the middle of the water outlet shell 3 in sequence. In the non-working state, water accumulates in the three water storage chambers, which can keep the ion membrane immersed in water for a long time. The wet ion membrane is used as a medium between the anode titanium sheet and the cathode titanium sheet and the diamond electrolytic sheet, which can enhance the conductive performance and prevent the ion membrane from drying out after the module is not working for a long time, thereby causing functional failure.

[0051] The constant power control circuit board 6 is installed in the top grooves 16 of the three diaphragm reaction chambers and is sealed on the surface with potting glue.

[0052] Through the above technical solution, this embodiment can ensure that the ozone concentration in water is greater than 1ppm when the water flow rate reaches 3000ml / min.

[0053] Diamond doped with boron has good conductivity, stable electrochemical properties, high oxygen evolution potential, wide potential window, low background current, and is not easy to adsorb organic matter or biological compounds on the electrode. It is resistant to acid and alkali corrosion and has a self-cleaning function. Therefore, the diamond film electrode sheet 10 uses a boron-doped diamond film.

[0054] The boron-doped diamond electrode used in this module is based on the diamond film boron oxide doped diamond electrode disclosed in CN112899644 A, and has the following characteristics: Physical properties: Easy deformation due to the uniformity and density of the diamond film: Due to the different temperatures on the two sides of the silicon wafer, the thickness on both sides is thin, warping and breakage will occur during the assembly of the module, thus affecting the electrolysis effect.

[0055] Chemical properties: The oxygen evolution potential is high, usually reaching above 2.8V, the electrochemical potential window is twice that of platinum, the thermal conductivity at room temperature is 5 times that of copper, and the hardness is 10 times that of corundum. It also has many excellent properties such as wear resistance, corrosion resistance, and radiation resistance.

In addition, the ozone concentration in the generated ozone water does not change with the change of water quality, and can meet the ozone concentration with disinfection effect required in the ozone water when the water flow is large, which can ensure accurate application in different scenarios.

[0057] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and these modifications and replacements should all fall within the scope of protection of the claims attached to the present invention.
