Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment parts, and particularly relates to a paper-based electrode. Background Art

[0002] With the improvement of living standards, people pay more and more attention to the air quality of the living environment. Therefore, various types of air purifiers have emerged. Currently, the mainstream air purifiers usually adopt two methods: filtering and adsorbing with a filter screen or forming an ionization field to filter the air. The ionization field filters the air mainly through the skin effect of the metal electrode set in the air purifier, so that a discharge phenomenon occurs when it is electrified to form an ionization field.

[0003] However, when using metal as the electrode during the ionization process, the metal will undergo electrocorrosion, and the metal particles generated after electrocorrosion will form metal dust floating in the air. If people inhale these metal dusts, it will cause serious harm to people's physical health. At the same time, the production cost of the metal electrode is relatively expensive, and the cost for users to replace the electrode is also relatively high. Summary of the Utility Model

[0004] The utility model provides a paper-based electrode. By setting a conductive layer on one side of a paper substrate infiltrated with a flame retardant to form a paper-based electrode capable of generating an ionization discharge phenomenon to replace the metal electrode, the electrocorrosion to produce metal dust harmful to the physical health of users is avoided, and the cost is reduced at the same time.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a paper-based electrode, including a paper substrate infiltrated with a flame retardant. A conductive layer is provided on one side of the paper substrate, and a sterilization layer and a photocatalytic layer are coated on the other side. The sterilization layer and the photocatalytic layer are arranged side by side on the same side of the paper substrate, and their positions are independently set and they work together.

[0006] The utility model is further arranged such that both the sterilization layer and the photocatalytic layer are composed of a number of independent small cells, and they are arranged in an alternating and staggered manner on one side surface of the paper substrate.

[0007] The utility model is further arranged such that the conductive layer is composed of graphene.

[0008] The utility model is further arranged such that the sterilization layer is formed by coating with concentrated iodine solution.

[0009] The utility model is further arranged such that the photocatalytic layer is formed by spraying with a titanium dioxide suspension.

[0010] The utility model is further arranged such that the conductive layer is provided at the middle position on one side of the paper substrate.

[0011] The present utility model is further configured such that the paper-based electrode is divided into an anode electrode and a cathode electrode. The edge of the conductive layer of the cathode electrode is serrated, and the edge of the conductive layer of the anode electrode is smooth.

[0012] In summary, the beneficial effects of the present utility model are as follows:

[0013] Compared with the prior art, in this application, by adding a paper substrate with a conductive layer, the paper substrate has the function of conductivity. After applying a high-voltage unidirectional pulse power supply to the paper-based electrode, an ionization discharge phenomenon can occur, and an electrostatic field is formed on the paper-based electrode, enabling the paper-based electrode to have an electrostatic adsorption effect, so that pollutants in the air can be oxidized, polarized, and adsorbed, achieving the effect of air purification, and can replace the metal electrodes in existing air purifiers; and compared with metal electrodes, using paper will not cause electric corrosion to generate floating dust, and due to the wettability of the paper substrate, the adsorption efficiency of pollutants is stronger; and the cost of the paper-based electrode is lower, and it can be naturally degraded after being discarded, without causing heavy metal pollution to the land and environment.

[0014] The paper substrate is infiltrated with a flame retardant, making the paper have the property of non-combustibility to prevent the paper electrode from igniting due to sparking; and the bactericidal layer and the photocatalytic layer provided on the same side of the paper substrate enable the paper substrate to kill bacteria, prevent bacteria from adsorbing on the surface of the paper substrate to "colonize" and reproduce, generating secondary pollution, and at the same time degrade the macromolecular organic matter adsorbed on the paper electrode into harmless small molecules, reducing the load of the paper electrode adsorbing organic matter and extending the working cycle of the paper electrode.

[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of the present utility model.

[0021] As Figures 1-4 shown, this embodiment discloses a paper-based electrode, which includes a paper substrate 1 infiltrated with a flame retardant. A conductive layer 2 is provided on one side of the paper substrate 1, and a bactericidal layer 3 and a photocatalytic layer 4 are coated on the other side. The paper substrate 1 is infiltrated with the flame retardant, enabling the paper to have non-combustible properties to prevent the paper electrode from igniting due to arcing and thus burning the electrode paper. The conductive layer 2 uses graphene coating, which can endow the paper substrate 1 with electrical conductivity. When a high-voltage unidirectional pulse is applied to this paper-based electrode, the paper-based electrode can generate an ionization discharge phenomenon and form an electrostatic field on the paper-based electrode, resulting in an electrostatic adsorption effect, enabling the oxidation and polarization of pollutant substances in the air and thus achieving the effect of air purification. It can replace the metal electrodes in existing air purifiers, avoiding the electrocorrosion of the electrodes in the ionization space and the generation of metal dust, thereby avoiding harm to the health of users. Moreover, compared with metal electrodes, the paper-based electrode has a lower manufacturing cost and is more convenient to replace. At the same time, since its material is paper, the paper-based electrode can be naturally degraded after being discarded and will not cause heavy metal pollution to the land and environment. Due to the wettability of the paper base, the adsorption efficiency of the paper-based electrode with the same area is higher than that of the metal electrode.

[0022] As Figures 1-2 shown, the bactericidal layer 3 and the photocatalytic layer 4 are arranged side by side on the same side of the paper substrate 1. The bactericidal layer 3 is formed by spraying concentrated iodine solution on the paper substrate 1. The concentrated iodine solution is a high-concentration iodine solution obtained by dissolving pure iodine in a sodium iodide solution. The photocatalytic layer 4 is formed by pouring titanium dioxide powder into a mixed solution of polyacrylamide solution and pure water to form a viscous homogeneous solution, and then spraying it on the paper substrate 1.

[0023] The bactericidal layer 3 composed of the concentrated iodine solution has the function of killing bacteria, preventing bacteria from adsorbing on the surface of the paper base and "colonizing" and multiplying, and generating secondary pollution.

[0024] When the photocatalytic layer 4 formed by spraying titanium dioxide suspension is irradiated by ultraviolet light in an air purifier and comes into contact with the macromolecular organic matter in the pollutant substances, it degrades them into harmless small molecules through the photoelectric effect, thereby reducing the adsorption load of the organic matter on the paper electrode and extending the working cycle of the paper electrode.

[0025] Meanwhile, both the sterilization layer 3 and the photocatalytic layer 4 are composed of a number of independent small cells, and they are arranged in an alternating and staggered manner on one side of the paper substrate 1. By arranging the sterilization layer 3 and the photocatalytic layer 4 in an alternating and staggered manner, the contact probability with pollutants can be increased, thereby making the sterilization or degradation effect better.

[0026] Moreover, titanium dioxide, as a widely used photocatalyst, will release part of its energy in the form of heat during the photocatalytic degradation of organic matter, thus generating heat. This heat can be conducted to the sterilization layer 3 arranged on the peripheral side of the photocatalytic layer 4, thereby realizing the heating of the sterilization layer 3, causing the sterilization layer 3 as a concentrated iodine solution to volatilize by heating, and further improving the sterilization efficiency. The heat generated by the photocatalytic layer 4 promotes the release of iodine in the sterilization layer 3. Compared with the independent arrangement of the sterilization layer 3 and the photocatalytic layer 4, the sterilization efficiency has been improved.

[0027] And as Figures 3-4 shown, the paper-based electrode can be divided into an anode electrode and a cathode electrode. The edge of the conductive layer 2 of the cathode electrode is serrated, which can cause the skin effect of the paper-based electrode, making the discharge ionization effect better, and thus making it easier to generate anions; while the edge of the conductive layer 2 of the anode electrode is smooth, and the U-shaped and smooth edge can prevent the anode electrode from discharging, thereby avoiding the release of positive ions by the anode electrode. By the anode electrode and the cathode electrode with different edge shapes of the conductive layer, an ionization space with a strong oxidation effect can be formed in the working environment, thereby better purifying the air.

[0028] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included within the protection scope of the present invention.
