Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning equipment, in particular to an air purification module and an air conditioner. Background Art

[0002] Currently, household appliances mostly use non-regenerative adsorption, photocatalysis, nano-water ion and other methods to purify the air and remove odors.

[0003] Traditional non-regenerative adsorption technology has the problem of secondary pollution after adsorption saturation, and the adsorption material needs to be replaced regularly. In addition, non-regenerative adsorption technology generally uses activated carbon materials as adsorbents. Due to the low adsorption capacity of activated carbon, more activated carbon materials need to be filled in the electrical appliances to quickly adsorb and purify harmful gases in the air, and this practice increases more air resistance for electrical appliances. Traditional photocatalytic technology requires ultraviolet light, which can easily cause aging effects on the machine and harm the human body. Since the high-energy particles generated by nano-water ion technology have a short life span and cannot effectively contact harmful gases, the use of nano-water ion technology cannot completely oxidize and remove odors, but will generate other new harmful gases. In addition, the use of nano-water ion technology is prone to produce by-products, such as ozone. Therefore, the use of nano-water ion technology will cause secondary pollution.

[0004] Therefore, the non-regenerative adsorption, photocatalysis, nano-water ion and other methods currently used in household appliances all have certain limitations and negative problems. Utility Model Content

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] The utility model provides an air purification module.

[0051] See also Figures 2 to 4 In one embodiment of the present invention, the air purification module 20 is provided for air to pass through, and the air purification module 20 includes:

[0052] A mounting shell 100 and a catalyst attachment body 200 mounted on the mounting shell 100, wherein an accommodation space is formed between the catalyst attachment body 200 and the mounting shell 100; and

[0053] The plasma generating device comprises two electrode members 300 disposed in the accommodation space, wherein the two electrode members 300 are a discharge electrode 410 and a counter electrode 420 respectively;

[0054] The electrode component 300 includes a substrate 310 and a plurality of electrode bodies 320 arranged on the substrate 310. The substrates 310 of the two electrode components 300 are distributed opposite to and spaced apart in a first direction. The electrode bodies 320 are arranged on opposite sides of the substrates 310 of the two electrode components 300 and extend along the first direction. The substrate 310 extends along a second direction. The plurality of electrode bodies 320 of the two electrode components 300 are distributed alternately and spaced apart in the second direction.

[0055] In the technical solution of the utility model, when air passes through the air purification module 20, plasma is generated by the plasma generating device, and the catalyst attached to the catalyst attachment body 200 can promote the reaction between the active particles generated by the plasma and the pollutants, thereby accelerating the conversion process. Specifically, the catalyst can capture and activate the active species generated by the plasma, such as free radicals and ions, so that they react more effectively with the target pollutants, thereby improving the removal rate of the pollutants. The presence of the catalyst can sometimes reduce the energy input required to achieve the same purification effect. In addition, the reaction path can be controlled by selecting a specific catalyst to reduce or avoid the production of harmful by-products, and some pollutants that are difficult to treat alone by plasma can become easy to treat with the assistance of a catalyst.

[0056] The utility model degrades odors and purifies the air through the synergistic effect of active particles and catalysts, avoiding the failure of traditional adsorption technology after saturation, so that the air purification module 20 does not need to perform module component replacement operations, and the air purification module 20 of the utility model can be used alone for air purification, so there is no need to be equipped with ultraviolet light sources and other components that are harmful to machine parts or human health, and the catalyst can eliminate by-products such as ozone generated by the plasma generator, thereby improving the mineralization rate of pollutants and avoiding secondary pollution.

[0057] Furthermore, in the utility model, the structure of the electrode component 300 itself is highly symmetrical, and the distribution method between the two electrode components 300 makes the symmetry between the two electrode components 300 also highly symmetrical. While making full use of the space in the accommodating space, it is beneficial to ensure the strength of the electric field generated between the two electrode components 300 and the uniformity of the distribution of the electric field, thereby ensuring the ionization efficiency of the air and the uniformity of the distribution of the generated plasma, which is beneficial to improving the concentration and stability of the plasma, so as to ensure the purification effect of the air purification module 20 on the air.

[0058] Without loss of generality, the plasma generating device of the present invention is configured as a non-thermal plasma generating device, which can achieve air purification in a more energy-efficient manner.

[0059] In one embodiment, the electrode body 320 of the discharge electrode 410 is provided with a discharge portion 411 on one side of the electrode body 320 facing the counter electrode 420, and the curvature radius of the discharge portion 411 is higher, and it can be configured as a sawtooth shape, a needle tip shape, a wolf tooth shape or a filament shape, etc., while the curvature radius of the outer surface of the counter electrode 420 is lower, and it can be configured as a round rod, a strip with thickness, etc. The greater the difference in the curvature radius between the two, the lower the high voltage required to excite the discharge, and the more intense the discharge under the same voltage. In this way, it is beneficial to improve the discharge efficiency between the discharge electrode 410 and the counter electrode 420, thereby increasing the ionization efficiency of the air and the concentration of the generated high-energy active particles, and the spatial distribution of the generated high-energy active particles is more uniform, so as to better purify the air and remove odors.

[0060] In some exemplary embodiments, the material of the discharge electrode 410 and the counter electrode 420 is metal, and a modifying material is provided on the surface. Specifically, the modifying material is provided on the metal material surface of the discharge electrode 410 and the counter electrode 420 to improve the conductivity of the discharge electrode 410 and the counter electrode 420 and improve the discharge efficiency of the plasma generating device of the utility model.

[0061] In some exemplary embodiments, the metal used in the discharge electrode 410 and the counter electrode 420 includes any one or more of stainless steel, copper, titanium, tungsten, and nickel, and the modification material includes any one or more of noble metals, carbon nanotubes, and graphene. Among them, the noble metal includes any one or more of silver, platinum, palladium, ruthenium, rhodium, and gold. Specifically, the corresponding metal and modification material can be selected according to the specific type of pollutants to be purified by the air purification module 20, the working parameters of the air purification module 20, the cost of the module itself, etc.

[0062] In some exemplary embodiments, the catalyst attached to the catalyst attachment body 200 includes any one or more of the following: hydrotalcite; molecular sieve modified by transition metal and / or precious metal; aluminum oxide modified by transition metal and / or precious metal. Among them, the transition metal includes any one or more of manganese, cerium, iron, copper, nickel, and lanthanum, and the precious metal includes any one or more of silver, platinum, palladium, ruthenium, rhodium, and gold. According to the working parameters of the air purification module 20, the corresponding filter metal and / or precious metal can be selected and set. Specifically, hydrotalcite can be used as an alkaline catalyst, a redox catalyst, and a catalyst carrier. Hydrotalcite also has ion exchange and adsorption effects, so hydrotalcite can be selected as a catalyst. Since transition metals and / or precious metals can catalyze and cross-couple organic compounds, the catalyst is set to a molecular sieve modified by transition metal and / or precious metal, and aluminum oxide modified by transition metal and / or precious metal, which can improve the degradation and decomposition of VOCs and the removal of odors of the air purification module 20 of the utility model. The corresponding catalyst can be selected according to the specific type of pollutants that the air purification module 20 needs to purify, the working parameters of the air purification module 20, the type of byproducts produced by the plasma generating device, and the cost of the air purification module 20 itself.

[0063] In one embodiment, the catalyst attachment 200 is configured as a honeycomb structure of insulating material. Insulating materials are not conductive, so the electric field distribution generated by the plasma can be maintained, so that the electric field can more effectively penetrate the catalyst layer, activate or accelerate the chemical changes in the catalytic reaction process, and prevent the electrode from directly contacting the catalyst, thereby avoiding the occurrence of arc discharge, protecting the safe operation of the equipment, and ensuring that the plasma reaction is carried out stably under control. The honeycomb structure has many through holes, which can promote the uniform distribution of gas, ensure that the reaction gas can fully contact the catalyst surface, and improve the catalytic efficiency and reaction uniformity. At the same time, the honeycomb structure also provides good mechanical support, increases the stability and durability of the catalyst attachment 200, especially under conditions where it is necessary to withstand gas flow pressure and vibration. In addition, the honeycomb structure helps heat exchange, can effectively manage the heat generated during the reaction, prevent local overheating, and protect the activity and stability of the catalyst. Of course, in other embodiments, the catalyst attachment 200 can also adopt other structures, such as a skeleton structure or a mesh structure, and the catalyst attachment 200 can also adopt a non-insulating material, and an insulating layer can be coated on the outside.

[0064] Furthermore, the catalyst attachment body 200 is one of a ceramic honeycomb, a glass fiber honeycomb, an alumina honeycomb, a fiberglass honeycomb, and a polymer honeycomb that meets the preset fire protection level requirements. Specifically, since the discharge electrode 410 and the counter electrode 420 are excited to discharge, when selecting a polymer honeycomb structure, it is necessary to meet the preset fire protection level requirements. For example, the fire protection level of the polymer honeycomb structure can reach 5VA level, and the material can be ABS (terpolymer of acrylonitrile-butadiene-styrene) plastic or ABS / PVC (polyvinyl chloride) mixed material or other plastics.

[0065] In one embodiment, the two electrode members 300 are located on the air inlet side of the catalyst attachment 200. In this way, the electric field generated by the electrode member 300 can act more directly on the newly entered reaction gas, promote its initial ionization or activation process, and accelerate the reaction rate. In addition, since the gas first contacts the electrode body 320 with a more open space, and then passes through the catalyst attachment 200 with a more compact structure, it is helpful to reduce the resistance to gas flow and ensure the gas flow rate. Of course, in other embodiments, both electrode members 300 can be located on the air outlet side of the catalyst attachment 200, or one electrode member 300 can be located on the air inlet side of the catalyst attachment 200, and the other electrode member 300 can be located on the air outlet side of the catalyst attachment 200.

[0066] In one embodiment, if Figure 4 , Figure 5 and Figure 8 As shown, the mounting shell 100 includes a first shell portion 110, the accommodating space is formed between the first shell portion 110 and the catalyst attachment body 200, and the electrode member 300 is connected to the first shell portion 110 and is spaced apart from the catalyst attachment body 200. In this way, the first shell portion 110 can provide the electrode member 300 with stable installation, ensuring that the electrode member 300 can be spaced apart from the catalyst attachment body 200 to avoid the generation of an electric arc, thereby avoiding the high temperature of the electric arc from damaging the plasma generating device, affecting the performance of the electrode 420 or the activity of the catalyst, and avoiding the safety hazards caused by the electric arc, or generating new pollutants. Specifically, the spacing between the electrode member 300 and the catalyst attachment body 200 is preferably 0.3 mm to 1 mm. Of course, in other embodiments, on the premise of meeting the use requirements of the air purification device, the spacing between the electrode member 300 and the catalyst attachment body 200 can also be adjusted to other values, such as less than 0.3 mm or more than 1 mm.

[0067] In one embodiment, if Figure 4As shown, the mounting shell 100 further includes a hook portion 111, which is protruding from the side of the first shell 110 facing the catalyst attachment body 200, and the electrode body 320 is hung on the side of the hook portion 111 away from the catalyst attachment body 200. In this way, the electrode body 320 is suspended on the hook portion 111, and the hook portion 111 can separate the electrode body 320 from the catalyst attachment body 200, so that the electrode member 300 as a whole maintains a certain distance from the catalyst attachment body 200 to avoid the generation of arcs.

[0068] Corresponding to one of the electrode bodies 320, the mounting shell 100 is provided with one hook portion 111 or multiple hook portions 111 are provided at intervals along the first direction. In practical applications, one or more hook portions 111 can be selectively provided to support one of the electrode bodies 320, as long as the electrode member 300 as a whole can be separated from the catalyst attachment body 200. When one hook portion 111 is provided corresponding to one of the electrode bodies 320, the contact area between the hook portion 111 and the electrode body 320 can be appropriately increased to effectively support the electrode body 320; when multiple hook portions 111 are provided corresponding to one of the electrode bodies 320, the multiple hook portions 111 can be distributed at intervals along the first direction, that is, the extension direction of the electrode body 320, to meet the support of the electrode 420. In this way, the electrode member 300 can be prevented from falling in the direction of the catalyst attachment body 200, so as to ensure that the electrode member 300 as a whole maintains a certain distance from the catalyst attachment body 200, thereby avoiding the generation of arcs. Furthermore, the hook portions 111 disposed on the mounting shell 100 are oriented in the same direction in the second direction, so that the electrode member 300 can be inserted from the side it is oriented to. In addition, the discharge portion 411 of the electrode body 320 is arranged to avoid the hook portion 111, so that the hook portion 111 can be engaged with the main body of the electrode body 320, so as to ensure the engagement stability of the electrode body 320 and the hook portion 111. Specifically, the discharge portion 411 of the electrode body 320 is provided with a notch 412 at a corresponding position for the hook portion 111 to be inserted.

[0069] In one embodiment, if Figures 5 to 7As shown, the plasma generating device further includes a limiting convex portion 330, which is convexly arranged on the side of the electrode member 300 facing the catalyst attachment body 200, and one or more limiting convex portions 330 are arranged on the electrode body 320. In this way, the limiting convex portion 330 can abut against the catalyst attachment body 200 to support the electrode member 300, so that the electrode member 300 can maintain a gap with the catalyst attachment body 200 to avoid the generation of arcs. It should be noted that the area where the limiting convex portion 330 abuts against the catalyst attachment body 200 should not be too large, and should be much smaller than the surface area of ​​the electrode member 300, so as to avoid the generation of arcs. When a plurality of limiting convex portions 330 are arranged on the electrode body 320, the plurality of limiting convex portions 330 are spaced apart in the first direction, or the limiting convex portions 330 are distributed on both opposite sides in the second direction, and both have the function of supporting the electrode 420 by lifting the limiting convex portions 330. Specifically, the limiting protrusion 330 can be integrally formed on the electrode component 300 by bending.

[0070] In one embodiment, if Figure 8 As shown, an isolation gasket 500 is sandwiched between the electrode member 300 and the catalyst attachment body 200. The isolation gasket 500 is arranged to avoid the discharge portion 411 of the discharge electrode 410, and the isolation gasket 500 is configured as an insulating material. It can be understood that the isolation gasket 500 should be provided with ventilation holes for air flow to pass through. At the same time, the discharge portion 411 of the discharge electrode 410 can be exposed from the ventilation holes of the isolation gasket 500, so that the plasma generating device can fully act on the gas flowing through, and at the same time facilitate the reaction of the active particles generated by it with the catalyst on the catalyst attachment body 200. In this embodiment, the electrode member 300 and the catalyst attachment body 200 are separated by the insulating isolation gasket 500, which can effectively ensure that there is a gap between the electrode member 300 and the catalyst attachment body 200, thereby avoiding the generation of arcs.

[0071] In one embodiment, if Figure 3 and Figure 4 As shown, the end of the substrate 310 is provided with a mounting hole 311 for a fastener to pass through, so that the electrode member 300 can be locked to the first shell 110. Specifically, the fastener can be a bolt, a screw or a rivet. In this way, the substrate 310 can be fixed to the first shell 110 by the fastener, further ensuring that there is a gap between the electrode member 300 and the catalyst attachment body 200, thereby avoiding the generation of arcs.

[0072] In one embodiment, if Figure 5 and Figure 8As shown, one end of the electrode body 320 away from the base 310 is bent to form an alignment convex portion 340, and the first shell portion 110 is correspondingly provided with an alignment slot 113, and the alignment convex portion 340 is correspondingly inserted into the alignment slot 113. Specifically, the alignment convex portion 340 can be formed by stamping. In this embodiment, the relative position of the electrode member 300 and the first shell portion 110 can be positioned by the cooperation of the alignment convex portion 340 and the alignment slot 113, so as to avoid the misaligned installation of the electrode member 300, so as to ensure the purification ability of the air purification module 20.
