Description

Technical Field

[0001] The invention belongs to the technical field of ozone preparation, and in particular relates to an ozone electrolysis chamber. Background Art

[0002] Ozone is recognized as a broad-spectrum and highly effective bactericide in the world. When ozone reaches a certain concentration, it can quickly kill bacteria in water and air. More importantly, ozone is reduced to oxygen after sterilization, so it is a green and environmentally friendly disinfectant. Ozone can be dissolved in water and form ozone water. In addition to killing bacteria in water, it can also decompose harmful pollutants such as organic matter in water, and at the same time has a certain decolorization effect on water.

[0003] At present, ozone is widely used in many countries and regions, such as in drinking water disinfection, medical water disinfection, sewage treatment, air disinfection in food factories and pharmaceutical factories, paper bleaching and other industries and fields. At the same time, some small-scale civilian ozone electrical products have also entered people's daily lives.

[0004] A Chinese patent (application number 201710333784.3) discloses an ozone generator nozzle, which is provided with a number of independent electrolysis chambers, and a positive electrode electrolysis chamber is provided in the middle of each electrolysis chamber, and negative electrode electrolysis chambers are provided on both sides of the positive electrode electrolysis chamber, and two cathodes, two PEM membranes, two diamond sheets and other components are provided inside the electrolysis chamber. However, since the electrodes in this patent are tightly fitted to the PEM membrane, it is difficult to make the ozone water produced by electrolysis flow, so the heat dissipation performance is poor, and the concentration of ozone water produced per unit area cannot be increased. The PEM membrane is also easily burned due to the inability of the electrode sheet to dissipate heat. In addition, the problem of scale treatment on the surface of the electrode has become a hot topic in the field of common research. The current common solution is to open holes on electrodes that are prone to scaling, use pure water as raw water, and increase the flow rate of water, so as to promote the flushing and timely discharge of scale.

[0005] In the current application of electrolysis to prepare ozone water, the design of the generating chamber used for electrolysis fails to meet the production requirements, which greatly limits the scope of ozone use. Therefore, it is extremely important to optimize the electrolysis structure. Summary of the invention

[0006] The object of the present invention is to provide an ozone electrolysis chamber to solve the problems raised in the above background technology.

[0007] The technical solution adopted to solve the above technical problems is as follows: an ozone electrolysis chamber, comprising a shell, wherein two ends of the shell are respectively provided with a water inlet and a water outlet, the inner cavity of the shell is an electrolysis chamber, at least one electrode sheet holder is provided in the electrolysis chamber, at least one group of electrolysis components is provided on the electrode sheet holder, the electrolysis components include an anode sheet, a proton exchange membrane and a cathode sheet installed on the electrode sheet holder in sequence from bottom to top, a water gap is left between the electrolysis component and the inner wall of the electrode sheet holder, the anode sheet is provided with a first water hole, the proton exchange membrane is provided with a second water hole corresponding to the first water hole, the first water hole is smaller than the second water hole, an elastic component is also provided in the electrolysis chamber, the two ends of the elastic component are respectively abutted against the cathode sheet and the inner wall of the shell, and the bottom side of the electrode sheet holder faces the water inlet.

[0008] Furthermore, a water dividing plate is provided at the bottom of the electrode sheet holder, and a plurality of third water passing holes corresponding to the first water passing holes are provided on the water dividing plate.

[0009] Furthermore, a mounting groove is provided at the bottom of the electrode sheet holder, a mounting protrusion is provided at the edge of the water divider plate, and the water divider plate is fixed to the bottom of the electrode sheet holder by snap-fitting connection between the mounting protrusion and the mounting groove.

[0010] Furthermore, an electrode sheet fixing piece is provided on the electrode sheet seat, and an electrolytic component installation position is formed between the electrode sheet fixing piece and the inner wall of the electrode sheet seat.

[0011] Furthermore, the number of electrolytic components on the electrode sheet holder is four groups, and two groups of electrolytic components are distributed on each side of the electrode sheet fixing member.

[0012] Furthermore, a conductive chip and a pressing block are provided on the surface of the electrode sheet fixing part, the conductive chip is provided with power connection pins extending outside the electrolysis chamber and a plurality of conductive contact pins attached to the surface of each anode sheet, and the pressing block is pressed onto the surface of the conductive chip.

[0013] Furthermore, a plurality of positioning posts are provided on the surface of the electrode sheet fixing member, and positioning holes matching with the positioning posts are provided on the surfaces of the conductive chip and the pressing block.

[0014] Furthermore, the anode plate is a diamond anode plate, and the cathode plate is a stainless steel cathode plate.

[0015] Furthermore, the shell includes a water inlet cover and a water outlet cover, and the water inlet cover and the water outlet cover are respectively fixed to the lower surface edge and the upper surface edge of the electrode sheet holder, and the electrolysis chamber is formed between the water inlet cover and the water outlet cover.

[0016] The present invention also provides an ozone electrolysis chamber application module, comprising a water flow pipe, the ozone electrolysis chamber is arranged on the peripheral wall of the water flow pipe, and the water outlet of the ozone electrolysis chamber is connected to the inside of the water flow pipe.

[0017] The technical solution of the present invention has the following advantages over the prior art:

[0018] 1. The ozone electrolysis chamber of the present invention arranges the anode sheet on the side close to the water inlet, so that the water flow can push open the cathode sheet after passing through the anode sheet and the proton exchange membrane, so that a gap is formed between the cathode sheet and the proton exchange membrane. At the same time, because the first water through hole is smaller than the second water through hole, after the water flow pushes open the cathode sheet, under the reaction force of the cathode sheet, the water flow will also form a gap between the anode sheet and the proton exchange membrane. The formed gap is conducive to the flow of ozone water generated by electrolysis, so the heat dissipation performance is better, which is conducive to increasing the concentration of ozone water generated per unit area, and the proton exchange membrane does not need to be always close to the electrode sheet to be burned.

[0019] 2. When the ozone electrolysis chamber of the present invention is used to prepare ozone water, the cathode plate is always in a micro-oscillation state under the action of water flow and elastic components, thereby preventing scale from accumulating on its surface, and the gap formed between the anode plate and the proton exchange membrane is also conducive to timely discharge of scale, thereby improving the service life of the electrode plate.

[0020] 3. An ozone electrolysis chamber application module of the present invention can use multiple ozone electrolysis chambers of the present invention at the same time, so it can produce a large flow of high-concentration ozone water in a short time and has a wide range of applications.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0034] The present invention provides an ozone electrolysis chamber.

[0035] Reference Figures 1 to 5The ozone electrolysis chamber of this embodiment includes a shell 1, and the two ends of the shell 1 are respectively provided with a water inlet 101 and a water outlet 102. The inner cavity of the shell 1 is an electrolysis chamber, and at least one electrode sheet holder 2 is provided in the electrolysis chamber. In this embodiment, the number of the electrode sheet holder 2 is one; at least one group of electrolysis components is provided on the electrode sheet holder 2, and the electrolysis components include an anode sheet 3, a proton exchange membrane 4 and a cathode sheet 5 installed on the electrode sheet holder 2 from bottom to top. In this embodiment, the number of electrolysis components on the electrode sheet holder 2 is four groups. Two groups of electrolytic components are distributed on both sides of the electrode sheet fixing part 201; a water gap 6 is left between the electrolytic component and the inner wall of the electrode sheet holder 2, a first water hole 301 is provided on the anode sheet 3, and a second water hole 401 corresponding to the first water hole 301 is provided on the proton exchange membrane 4, and the first water hole 301 is smaller than the second water hole 401. An elastic component 7 is also provided in the electrolytic chamber, and the two ends of the elastic component 7 are respectively abutted against the cathode sheet 5 and the inner wall of the shell 1, and the bottom side of the electrode sheet holder 2 faces the water inlet 101. During the electrolysis process, ozone and oxygen are generated between the anode sheet 3 and the proton exchange membrane 4, and hydrogen is generated between the cathode sheet 5 and the proton exchange membrane 4. These gases will form tiny gaps between the anode sheet 3 and the proton exchange membrane 4 and between the cathode sheet 5 and the proton exchange membrane 4. The anode sheet 3 is arranged on the side close to the water inlet 101. After the water flows through the anode sheet 3 and the proton exchange membrane 4, it can push open the cathode sheet 5, so that the gap between the cathode sheet 5 and the proton exchange membrane 4 is further expanded. At the same time, since the first water hole 301 is smaller than the second water hole 401, after the water flows open the cathode sheet 5, under the reaction force of the cathode sheet 5, the water flows will also further expand the gap between the anode sheet 3 and the proton exchange membrane 4. Therefore, the heat dissipation performance is better, and the expanded gap is conducive to the flow and discharge of the gas and ozone water generated by electrolysis, which is conducive to increasing the concentration of ozone water generated per unit area. The proton exchange membrane 4 also does not need to be burned out by always being close to the electrode sheet, thereby increasing the service life of the proton exchange membrane 4. At the same time, under the action of the water flow and the elastic component 7, the cathode sheet 5 is always in a micro-oscillation state, so it can prevent scale from accumulating on its surface, and the gap formed between the anode sheet 3 and the proton exchange membrane 4 is also conducive to timely discharge of scale, and the service life of the electrode sheet is improved. In addition, part of the ozone and oxygen generated between the anode sheet 3 and the proton exchange membrane 4 will be discharged from the water gap 6 in the form of bubbles. These bubbles will rebound to the surface of the cathode sheet 5 after hitting the top of the inner wall of the shell 1, and then rebound to the water outlet 102, that is, discharged in an "N"-shaped route. When rebounding to the surface of the cathode sheet 5, it will play an auxiliary role in removing the scale attached thereto.

[0036] Reference Figure 4 and Figure 5In this embodiment, preferably, a water diversion plate 8 is provided at the bottom of the electrode sheet holder 2, and a plurality of third water holes 801 corresponding to the first water holes 301 are provided on the water diversion plate 8. Compared with the disordered water flow formed when there is no water diversion plate 8, the water diversion plate 8 can divert the water flow entering from the water inlet 101 and pass the water flow to the electrolysis component in an orderly manner through the third water holes 801, thereby greatly improving the electrolysis efficiency. In this embodiment, a mounting groove is provided at the bottom of the electrode sheet holder 2, and a mounting protrusion is provided at the edge of the water diversion plate 8. The water diversion plate 8 is fixed to the bottom of the electrode sheet holder 2 by the snap-fit ​​connection between the mounting protrusion and the mounting groove.

[0037] Preferably, the electrode sheet holder 2 is provided with an electrode sheet fixing member 201, and an electrolytic component installation position 203 is formed between the electrode sheet fixing member 201 and the inner wall of the electrode sheet holder 2, and the electrolytic component installation position 203 serves as an installation limit for the electrolytic component. Figure 3 The two ends of the electrode sheet fixing part 201 are respectively fixedly connected to the inner walls on both sides of the electrode sheet holder 2. The surface of the electrode sheet fixing part 201 and the other two inner walls of the electrode sheet holder 2 are respectively provided with clamping angles. The clamping angles on the inner walls on both sides of the electrode sheet holder 2 correspond to the clamping angles on the surface of the electrode sheet fixing part 201 to form an electrolytic component installation clamping position 203.

[0038] Reference Figure 5 The surface of the electrode sheet fixing part 201 is provided with a conductive chip 9 and a pressing block 10. The conductive chip 9 is provided with a power connection pin extending out of the electrolysis chamber and a plurality of conductive contact pins attached to the surface of each anode sheet 3. The pressing block 10 is pressed onto the surface of the conductive chip 9. In addition, the power connection pins of the cathode sheet 5 and the power connection pins of the conductive chip 9 extend out of the electrolysis chamber together. At the same time, the conductive chip 9 is completely isolated from water and the electrolysis chamber is completely isolated from the outside through the sealing treatment, thereby ensuring the safe conduct of the electrolysis process.

[0039] In this embodiment, a plurality of positioning posts 202 are provided on the surface of the electrode sheet fixing part 201, and positioning holes matching with the positioning posts 202 are provided on the surfaces of the conductive chip 9 and the pressing block 10. The positioning holes are provided to facilitate the positioning and installation of the conductive chip 9 and the pressing block 10. It should be noted that there is no specific restriction on the fixing method of the pressing block 10. In order to facilitate the fixing of the pressing block 10, in this embodiment, the fixing of the pressing block 10 can be achieved by means of interference fit between the positioning posts 202 and the positioning holes on the pressing block 10, or by providing bolt holes on the pressing block 10 and the electrode sheet fixing part 201, so as to achieve fixing by bolt connection.

[0040] In this embodiment, the anode sheet 3 is preferably a diamond anode sheet, and the cathode sheet 5 is preferably a stainless steel cathode sheet. The diamond anode sheet and the stainless steel cathode sheet are not easily worn out during the electrolysis process, which can effectively increase the service life of the electrolysis component.

[0041] The elastic component 7 can be preferably a tower spring, a spring or a spring sheet. In this embodiment, the elastic component 7 is a tower spring, and a cylindrical stopper 105 is provided on the inner wall of the housing 1. The small end of the tower spring abuts against the inner wall of the housing 1 and cooperates with the cylindrical stopper 105, that is, the cylindrical stopper 105 is inserted into the small end of the tower spring to limit the movement of the tower spring, and the large end of the tower spring abuts against the cathode sheet 5. The tower spring can enable the cathode sheet 5 to achieve elastic reset after a violent electrolytic reaction to ensure the accuracy and reliability of the position.

[0042] In this embodiment, the housing 1 includes a water inlet cover 103 and a water outlet cover 104, which are respectively fixed to the lower surface edge and the upper surface edge of the electrode sheet holder 2, and an electrolysis chamber is formed between the water inlet cover 103 and the water outlet cover 104. Specifically, the connection between the electrode sheet holder 2 and the water inlet cover 103 and the water outlet cover 104 is achieved by snap-fit ​​connection and bolt connection, so as to facilitate assembly and installation of the electrode sheet holder 2, and the ozone water concentration generated by the ozone electrolysis chamber after the electrode sheet holder 2 is installed is higher.

[0043] Reference Figure 6 In another embodiment, the number of electrode sheet holders 2 in the electrolysis chamber is two, and a water dividing plate 8 is also provided between the two electrode sheet holders 2. The connection modes between the water dividing plate 8 and the upper and lower electrode sheet holders 2 are both snap-fit ​​connection and bolt connection. An elastic component 7 is also provided between the water dividing plate 8 and the lower electrode sheet holder 2, and the two ends of the elastic component 7 are respectively in contact with the surface of the cathode sheet 5 and the bottom of the water dividing plate 8. By increasing the number of electrode sheet holders 2, the production efficiency of ozone and the concentration of ozone water can be improved. At the same time, it can avoid the situation that the entire ozone electrolysis chamber cannot work when the electrolytic component on one electrode sheet holder 2 fails.

[0044] The invention provides an ozone electrolysis chamber module.

[0045] The ozone electrolysis chamber application module of the present embodiment includes a water flow pipe 11, and a plurality of ozone electrolysis chambers as described above are arranged on the peripheral wall of the water flow pipe 11. The water outlet 102 of the ozone electrolysis chamber is connected to the interior of the water flow pipe 11. Preferably, the water outlet 102 is threadedly connected to the pipe. The present invention can use a plurality of the above-mentioned ozone electrolysis chambers at the same time, so that a large flow of high-concentration ozone water can be generated in a short time, and the water can be converged and output through the water flow pipe 11. The scope of use is extremely wide, and even if individual ozone electrolysis chambers are damaged, it will not affect the overall operation of the application module, and the damaged ozone electrolysis chamber can also be easily disassembled and replaced. Refer to Figure 7 In this embodiment, the water flow pipe 11 is a circular pipe.

[0046] Reference Figure 8In another embodiment, the water flow pipe 11 is a square pipe, and the ozone electrolysis chambers are distributed on both sides or one side of the square pipe.

[0047] In some other embodiments, the cross-sectional shape of the water flow conduit may be a triangle or other shapes without limitation.
