Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to an ozone water machine. Background Art

[0002] The existing ozone water machine mainly includes two links, one is the ozone production link, and the other is the link of mixing ozone gas with water.

[0003] There are two ways to produce ozone. One is to use pure oxygen as the oxygen source. The ozone produced at this time is relatively pure and does not contain other associated substances. The other is to use air as the oxygen source and then generate ozone through an ozone generator. At this time, due to the high-frequency and high-voltage power supply of the ozone generator, the nitrogen in the air will also react to generate nitrogen oxides, that is, harmful gases. In other words, the existing technology cannot produce ozone through an air source without the generation of harmful products.

[0004] The process of mixing ozone gas with water is usually carried out by Figure 1 The ejector structure shown adopts a venturi tube. Since the structural dimensions of the venturi tube itself have specific requirements, the mixing effect of each venturi tube on gas and water has a limit. Such a structure also limits the further full mixing of ozone and water.

[0005] In addition, the ozone generator generates a lot of heat during operation, which will lead to a decrease in ozone production. Most ozone generators use fresh air (or oxygen) to cool the ozone generator, but the air cooling effect is poor; and the use of independent water cooling requires a separate set of water cooling pipelines, which is complex in structure. Summary of the invention

[0006] The object of the present invention is to provide an ozone water machine to solve the problems of complex water cooling structure of the ozone generator and inability to fully mix ozone and water in view of the above-mentioned defects.

[0007] The ozone water machine includes:

[0008] A water pipe joint, a ground electrode pipe, a high-voltage electrode pipe, an inner joint, an outer sleeve, an insulating pipe, a gas-water mixing structure, a gas-water dispersion structure and a high-frequency high-voltage power supply, wherein the ground electrode pipe is a long straight round pipe, the interior of which is used for water to pass through, the high-voltage electrode pipe is sleeved on the outside of the ground electrode pipe, and there is a gap between the ground electrode pipe and the high-voltage electrode pipe; the inlet ends of the ground electrode pipe and the high-voltage electrode pipe are connected to the water pipe joint, and the outlet end of the ground electrode pipe is sealed with the outer sleeve and the inner joint therein; the outlet end of the inner joint is connected to the water inlet of the gas-water mixing structure;

[0009] The gas-water mixing structure is located in the outer sleeve, including an outer shell, a first-level injection mixing structure, and a second-level injection mixing structure. The outer shell is sealed and connected to the inner joint. The first-level injection mixing structure and the second-level injection mixing structure are arranged in the outer shell in sequence according to the flow direction of the fluid; wherein a plurality of gas inlets are evenly arranged on the circumference of the outer shell, and the gas inlet is located between the outer shell, the first-level injection mixing structure, and the second-level injection mixing structure.

[0010] The high-voltage electrode tube is an insulating tube. As a dielectric barrier structure, a high-voltage electrode is arranged outside the high-voltage electrode tube, so that the gap between the high-voltage electrode tube and the ground electrode tube serves as a discharge gap: the gas inlet is connected to the discharge gap through a through hole or channel arranged in the outer sleeve, and the discharge gap is connected to the outside through the high-voltage electrode tube or the water pipe joint on the side of the water pipe joint; or the discharge gap is filled with inert gas as an excitation medium. In this case, the high-voltage electrode tube adopts a light-transmitting quartz tube or glass tube, the gas inlet is connected to the gap between the high-voltage electrode tube and the insulating tube through a through hole or channel arranged in the outer sleeve, and the gap between the high-voltage electrode tube and the outer sleeve is connected to the outside through the insulating tube or the water pipe joint on the side of the water pipe joint;

[0011] The air-water dispersion structure is installed in the outer casing and is located downstream of the air-water mixing structure.

[0012] The inert gas is xenon or a mixture of xenon and other gases.

[0013] When the discharge gap is filled with an inert gas, the high voltage electrode is a mesh electrode, a strip electrode or a spiral electrode.

[0014] When the discharge gap is connected to the gas inlet, the high-voltage electrode is a coating or patch arranged on the outer wall of the high-voltage electrode tube to ensure that the distance between the high-voltage electrode and the ground electrode tube is equal at all locations.

[0015] When the high-voltage electrode is a spiral electrode, the thickness of the spiral electrode is equal to or slightly smaller than the gap distance between the high-voltage electrode tube and the outer sleeve, thereby forming a spiral path between the high-voltage electrode tube and the outer sleeve, forcing the gas to move in a spiral manner along the spiral electrode.

[0016] The inner joint is a tubular structure.

[0017] The insulating pipe, outer casing and water pipe joints are made of insulating materials.

[0018] The gas channel includes air holes arranged on the walls of the insulating tube and the high-voltage electrode tube; or the gas channel includes a channel arranged on the water pipe joint and connected to the discharge gap.

[0019] The gas-water mixing structure is connected to the inner joint through threads.

[0020] The first-stage injection mixing structure includes a plurality of first cone tubes, the large-diameter end of the first cone tube is located upstream, and the small-diameter end is located downstream; the second-stage injection mixing structure includes a plurality of second cone tubes, the first cone tubes and the second cone tubes correspond one to one, and the inner diameter of the small-diameter end of the second cone tube is larger than the inner diameter of the small-diameter end of the first cone tube.

[0021] The ozone water machine provided by the present invention forms an ozone generating structure and a gas-water mixing structure in an integrated manner, utilizes a ground electrode tube as a cooling tube of the ozone generating structure, and also as a ground electrode of the ozone generating structure, thereby realizing a very simple ozone generating structure; at the same time, the generated ozone gas is directly passed through the space between the outer sleeve and the gas-water mixing structure to enter the gas-water mixing structure, thereby fully mixing the ozone gas and water under the action of the jet; further, by filling an inert gas medium into the discharge gap, utilizing the excitation effect of a high-frequency high-voltage electric field, the inert gas generates vacuum ultraviolet light, and utilizing the vacuum ultraviolet light to irradiate the gas passing between the high-voltage electrode tube and the insulating tube, thereby generating ozone from the oxygen therein, while the nitrogen remains unchanged, and thus no nitrogen oxides are generated.

[0022] Other features and advantages of the present invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 2-3 As shown, this embodiment provides the ozone water machine, including:

[0031] A water pipe joint 1, a ground electrode tube 2, a high-voltage electrode tube 3, an inner joint 4, an outer sleeve 5, an insulating tube 6, a gas-water mixing structure 7, a gas-water dispersion structure 8 and a high-frequency high-voltage power supply 9, wherein the ground electrode tube 2 is a long straight round tube, the interior of which is used for water to pass through, the high-voltage electrode tube 3 is sleeved on the outside of the ground electrode tube 2, and there is a gap between the ground electrode tube 2 and the high-voltage electrode tube 3; the inlet ends of the ground electrode tube 2 and the high-voltage electrode tube 3 are connected to the water pipe joint 1, and the outlet end of the ground electrode tube 2 is sealedly connected to the outer sleeve 5 and the inner joint 4 therein (the inner joint 4 is a hollow pipeline structure, and its function is to connect the ground electrode tube 2 and the outer shell 71 of the gas-water mixing structure 7, so that the water passes through the inner structure 4 and directly enters the gas-water mixing structure 7); the outlet end of the inner joint is connected to the water inlet of the gas-water mixing structure;

[0032] The gas-water mixing structure 7 is located in the outer sleeve 5, and includes an outer shell 71, a first-level jet mixing structure 72, and a second-level jet mixing structure 73. The outer shell 71 is sealed and connected to the inner joint, and the first-level jet mixing structure and the second-level jet mixing structure are arranged in the outer shell in sequence according to the flow direction of the fluid; wherein the circumference of the outer shell is evenly provided with a plurality of gas inlets, and the gas inlets are located between the outer shell, the first-level jet mixing structure, and the second-level jet mixing structure. The gas-water mixing structure 7 is an assembly, wherein the outer shell 71 is directly and sealedly connected to the inner joint 4, so that water can directly enter without leakage; the outer wall of the outer shell 71 also needs to be sealed and connected to the inner wall of the outer sleeve 5, and the sealing position needs to be close to the outlet end to ensure that the gas inlet 70 can be connected to the gas outlet end of the ozone generating structure along the gap or channel between the outer wall of the outer shell 71 and the inner wall of the outer sleeve 5. The gas outlet end is at Figure 2 In the structure shown, it is the discharge gap between the ground electrode tube 2 and the high-voltage electrode tube 3; the gas outlet is at Figure 3 In the structure shown, it is the gap between the insulating tube 6 and the high-voltage electrode tube 3. In order to enable the gas inlet 70 to communicate with the gas outlet of the ozone generating structure, it is usually necessary to set a ventilation channel at the part of the outer sleeve 5 connected to the ground electrode tube 2 or the inner joint 4.

[0033] The high-voltage electrode tube is an insulating tube, which serves as a dielectric barrier structure. A high-voltage electrode is arranged outside the high-voltage electrode tube, so that the gap between the high-voltage electrode tube and the ground electrode tube serves as a discharge gap. There are two specific implementation methods:

[0034] The first implementation method is as follows Figure 2As shown, the gas inlet 70 is connected to the discharge gap through a through hole or channel provided in the outer sleeve, and the discharge gap is connected to the outside through the high-voltage electrode tube or water pipe joint on one side of the water pipe joint;

[0035] The second implementation method is as follows Figure 3 As shown, the discharge gap is filled with an inert gas 10 as an excitation medium. At this time, the high-voltage electrode tube adopts a light-transmitting quartz tube or glass tube. The gas inlet 70 is connected to the gap between the high-voltage electrode tube and the insulating tube 6 through a through hole or channel set in the outer sleeve, and the gap between the high-voltage electrode tube and the outer sleeve is connected to the outside through an insulating tube or a water pipe joint on one side of the water pipe joint; the inert gas 10 is xenon or a mixed gas of xenon and other inert gases and non-excitation gases (non-inert gases that do not generate ultraviolet light under the action of high-frequency and high-voltage electric fields). In order to ensure that xenon does not leak, it is also necessary to seal the two ends of the ground electrode tube 2 and the high-voltage electrode tube 3 with a sealing structure, and it is necessary to consider the stability of the sealing structure under vacuum ultraviolet radiation. When necessary, a complex labyrinth structure needs to be used for sealing, that is, the sealing colloid part is shielded by a labyrinth structure to prevent the sealing colloid from being irradiated by vacuum ultraviolet light and becoming ineffective. Figure 3 The ground electrode tube 2, the inert gas 10 and the high-voltage electrode tube 3 shown in the figure form a quasi-molecular light-emitting structure, which can generate vacuum ultraviolet light under the action of a high-frequency and high-voltage electric field.

[0036] The air-water dispersion structure is installed in the outer casing and is located downstream of the air-water mixing structure.

[0037] When the discharge gap is filled with an inert gas, the high voltage electrode is a mesh electrode, a strip electrode or a spiral electrode.

[0038] When the discharge gap is connected to the gas inlet, the high-voltage electrode is a coating or patch arranged on the outer wall of the high-voltage electrode tube to ensure that the distance between the high-voltage electrode and the ground electrode tube is equal at all locations.

[0039] When the high-voltage electrode is a spiral electrode, the thickness of the spiral electrode is equal to or slightly smaller than the gap distance between the high-voltage electrode tube and the outer sleeve, thereby forming a spiral path between the high-voltage electrode tube and the outer sleeve, forcing the gas to advance in a spiral manner along the spiral electrode. In this way, a longer gas travel path can be obtained, so that the air can be irradiated more by vacuum ultraviolet light, and more ozone can be produced. In this way, a better ozone yield can be obtained without extending the length of the ozone generating structure.

[0040] The insulating pipe, outer casing and water pipe joints are made of insulating materials.

[0041] The gas channel includes air holes arranged on the walls of the insulating tube and the high-voltage electrode tube; or the gas channel includes a channel arranged on the water pipe joint and connected to the discharge gap.

[0042] The gas-water mixing structure is connected to the inner joint through threads.

[0043] The first-stage injection mixing structure includes a plurality of first cone tubes, the large-diameter end of the first cone tube is located upstream, and the small-diameter end is located downstream; the second-stage injection mixing structure includes a plurality of second cone tubes, the first cone tubes and the second cone tubes correspond one to one, and the inner diameter of the small-diameter end of the second cone tube is larger than the inner diameter of the small-diameter end of the first cone tube.

[0044] The ozone water machine provided by the present invention forms an ozone generating structure and a gas-water mixing structure in an integrated manner, utilizes a ground electrode tube as a cooling tube of the ozone generating structure, and also as a ground electrode of the ozone generating structure, thereby realizing a very simple ozone generating structure; at the same time, the generated ozone gas is directly passed through the space between the outer sleeve and the gas-water mixing structure to enter the gas-water mixing structure, thereby fully mixing the ozone gas and water under the action of the jet; further, by filling an inert gas medium into the discharge gap, utilizing the excitation effect of a high-frequency high-voltage electric field, the inert gas generates vacuum ultraviolet light, and utilizing the vacuum ultraviolet light to irradiate the gas passing between the high-voltage electrode tube and the insulating tube, thereby generating ozone from the oxygen therein, while the nitrogen remains unchanged, and thus no nitrogen oxides are generated.

[0045] Related technical information:

[0046] The principle of ordinary ultraviolet sterilization is to destroy the molecular structure of the DNA or RNA of microorganisms, making it impossible for them to replicate and transcribe normally, thereby causing the death of the microorganisms; in fact, it uses the light energy of ultraviolet rays to destroy and open the molecular bonds of cells.

[0047] The relationship between ultraviolet wavelength and energy is that the shorter the wavelength, the greater the energy.

[0048] The relationship between wavelength and energy is E=hc / λ, where E represents energy, h is Planck's constant, c is the speed of light in a vacuum, and λ is the wavelength.

[0049] Vacuum ultraviolet (VUV) is named because ultraviolet rays in this band are strongly absorbed by oxygen in the air and can only be used in a vacuum. The wavelength range of vacuum ultraviolet (VUV) is roughly between 10-200nm, and only ultraviolet radiation with a wavelength greater than 200nm can propagate in the air.

[0050] The characteristics of vacuum ultraviolet light also include its high energy and relatively weak penetrating power, which makes it effective in areas such as disinfection and sterilization. Despite its poor penetrating power, it is very useful in applications that require highly concentrated energy.

[0051] In general, vacuum ultraviolet light is a special type of ultraviolet light, and its unique properties enable it to play an important role in scientific research and technological applications, especially in application scenarios that require high-energy, highly concentrated energy.

[0052] The reason why vacuum ultraviolet can only be used in a vacuum is that high-energy light waves will be absorbed by the oxygen and nitrogen in the air after coming into contact with the air, and thus cannot propagate in the air.

[0053] The bond energy of oxygen molecule is 498KJ / mol, and the corresponding absorption wavelength is 195nm.

[0054] That is to say, only vacuum ultraviolet light with a wavelength below 195nm can open the molecular bonds of oxygen.

[0055] The bond energy of nitrogen molecule is 946 kJ / mol, and the corresponding absorption wavelength is 145 nm.

[0056] That is to say, only vacuum ultraviolet light with a wavelength below 145nm can open the molecular bonds of nitrogen.

[0057] The wavelengths of vacuum ultraviolet light emitted by excimer laser are 157nm, 172nm, and 193nm.

[0058] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0059] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
