Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an improvement in the structure of an air purification device. Background Art

[0002] The existing technologies for deodorization mainly rely on materials with adsorption properties, such as activated carbon, to physically adsorb odor substances in the air. The adsorption temperature has a great influence on the adsorption effect of the adsorption material. The lower the adsorption temperature, the better the adsorption effect. The higher the temperature, the higher the kinetic energy of the odor molecules and the more difficult they are to capture.

[0003] The existing adsorption materials mainly consist of activated carbon and molecular sieves. During adsorption, the adsorbates are mainly arranged in the adsorption area for normal-temperature adsorption, and the temperature of the adsorption material is not effectively controlled, resulting in the re-desorption of some substances with lower boiling points, such as ammonia and hydrogen sulfide, after adsorption, generating secondary odor substances.

[0004] To achieve a better adsorption effect, it is necessary to increase the thickness of the adsorption coating. Using an adsorption coating with a higher thickness causes a large resistance to the equipment and higher operating energy consumption.

[0005] Moreover, the surface micropore size of adsorption materials such as activated carbon and molecular sieves at normal temperature is uncontrollable. Therefore, there is no selectivity in the adsorption of odor gases, easily resulting in the situation that some odor gases cannot be adsorbed, and there is a problem of insufficient adsorption.

[0006] After the adsorption material is saturated, it needs to be disassembled and placed in a special desorption and regeneration device for heating desorption, and the heating desorption operation is cumbersome and inconvenient.

[0007] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Utility Model

[0008] Aiming at the problems of insufficient adsorption, poor adsorption effect, and inconvenient desorption operation pointed out in the background art, a new type of air purification device is proposed, which can not only improve the adsorption performance of the adsorption coating but also facilitate the desorption after adsorption saturation.

[0009] To achieve the above utility model purpose, the present utility model adopts the following technical solutions:

[0010] In some embodiments of the present application, an air purification device is provided, including:

[0011] An adsorption matrix, on which an adsorption coating is provided, and the adsorption coating is configured to: adsorb and purify the air flow passing through it.

[0012] A heat exchange component, for heat exchange, is installed on the adsorption matrix. A heat exchange channel for introducing a heat exchange medium is formed inside the heat exchange component. The heat exchange channel is configured to: perform heat exchange between the heat exchange medium introduced into it and the adsorption coating to adjust the temperature of the adsorption coating.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are:

[0014] In the air purification device of the present utility model, by installing a heat exchange component on the adsorption matrix, different temperature refrigerants can be introduced into the heat exchange component according to different usage situations during use: when performing adsorption, a low-temperature refrigerant can be introduced to exchange heat with the adsorption coating on the adsorption matrix to cool the adsorption coating, thereby increasing the activity of the adsorbed substances in the adsorption coating, ensuring the sufficiency of adsorption, and improving the adsorption performance;

[0015] By introducing a high-temperature refrigerant to exchange heat with the adsorption coating on the adsorption matrix to heat the adsorption coating, the adsorption coating after adsorption saturation can be heated and desorbed for regeneration, without placing the entire device into a desorption heating device for desorption, and the desorption operation is more convenient.

[0036] In some embodiments of the present application, an air purification device is provided, including:

[0037] An adsorption matrix, on which an adsorption coating 110 is coated, and the adsorption coating 110 is configured to: adsorb and purify the air flow passing through it.

[0038] The adsorption matrix is a carrier for the adsorption coating 110, and the adsorption coating 110 realizes its corresponding adsorption function by being coated on the adsorption matrix.

[0039] The adsorption coating 110 coated on the adsorption matrix can be coated on the outer surface of the adsorption matrix or inside the adsorption matrix.

[0040] To ensure that the air flow passing through the adsorption matrix is adsorbed and purified, the adsorption coating 110 coated on the adsorption matrix is configured to: be on the flow path of the air flow passing through the adsorption matrix, so that when the air flow passes through the adsorption matrix, it will necessarily pass through the adsorption coating 110, and the adsorption coating 110 adsorbs and deodorizes and purifies the air flow.

[0041] In some embodiments, the adsorption coating 110 is an adsorption coating 110 composed of porous adsorption materials such as activated carbon, molecular sieve or graphene, with micropores on the surface, and the air flow passing through it can be adsorbed through the micropores.

[0042] In some embodiments, the adsorption coating 110 is loaded with titanium dioxide and manganese-based catalysts. Titanium dioxide can undergo a photo-oxygen catalytic reaction with ultraviolet light to generate a large amount of hydroxyl radicals, thereby decomposing some malodorous gases. At the same time, the manganese-based catalyst has a good decomposition effect on aldehyde-based malodorous substances. Therefore, the purification effect of the present deodorization device on malodorous gases can be greatly improved.

[0043] A heat exchange component 200, installed on the adsorption matrix, and a heat exchange channel 210 for introducing a heat exchange medium is formed inside the heat exchange component 200.

[0044] The heat exchange channels 210 inside the heat exchange component 200 are mainly used for introducing a heat exchange medium, and the heat exchange medium is a refrigerant with a set temperature.

[0045] The heat exchange channels 210 are configured to: perform heat exchange with the adsorption coating through the heat exchange medium introduced into them to adjust the temperature of the adsorption coating 110.

[0046] The heat exchange component 200 mainly exchanges heat by directly or indirectly transferring energy between the heat exchange medium flowing inside the heat exchange channels 210 and the adsorption coating 110.

[0047] The heat exchange component 200 is installed on the adsorption substrate, realizing a direct connection with the adsorption substrate. After introducing a heat exchange medium into the heat exchange channels 210 inside it, it will exchange heat with the adsorption substrate connected to the heat exchange component 200 and indirectly exchange heat with the adsorption coating 110 to realize the temperature adjustment of the adsorption coating 110.

[0048] Alternatively, after introducing a heat exchange medium into the heat exchange component 200, the heat exchange component 200 is in direct contact with the adsorption coating 110 and directly exchanges heat with the adsorption coating 110 to adjust the temperature of the adsorption coating 110.

[0049] By introducing heat exchange media with different temperatures into the heat exchange channels 210 and performing heat exchange with the adsorption coating 110, the functions of raising or lowering the temperature of the adsorption coating 110 can be realized.

[0050] In some embodiments, when a heat exchange medium with a lower temperature is introduced into the heat exchange component 200, since the temperature of the heat exchange medium in the heat exchange channels 210 is very low, it will exchange heat with the adsorption substrate and absorb heat, causing the temperature of the adsorption substrate and the adsorption coating 110 to decrease. The decrease in the temperature of the adsorption coating 110 makes it easier for the micropores on the surface of the adsorption coating 110 material to capture volatile gas components in the air, thereby achieving the purpose of improving the deodorization and purification effect.

[0051] In some embodiments, when a heat exchange medium with a higher temperature is introduced into the heat exchange component 200, the heat exchange medium in the heat exchange channels 210 with a high temperature will release heat, and then transfer the heat to the adsorption substrate. The adsorption substrate transfers the heat to the adsorption coating 110 coated on it to raise the temperature of the adsorption coating 110. The increase in the temperature of the adsorption coating 110 causes the previously adsorbed odor gas components to volatilize again, thereby realizing the function of desorption and regeneration.

[0052] The air purification device installs a heat exchange component 200 on the adsorption matrix, so that different temperature refrigerants can be introduced into the heat exchange component 200 according to different usage situations during use: when adsorbing, low-temperature refrigerant can be introduced to exchange heat with the adsorption coating 110 on the adsorption matrix to cool the adsorption coating 110, so as to improve the activity of the adsorbed substances in the adsorption coating 110, ensure the sufficiency of adsorption, and improve the adsorption performance;

[0053] By introducing high-temperature refrigerant to exchange heat with the adsorption coating 110 on the adsorption matrix to heat up the adsorption coating 110, the adsorption coating 110 after adsorption saturation can be heated and desorbed for regeneration. When desorption regeneration is required, only high-temperature refrigerant needs to be introduced into the heat exchange component 200, and there is no need to place the entire device into a desorption heating device for desorption, and the desorption operation is more convenient.

[0054] By introducing different temperature refrigerants into the heat exchange component 200, the rapid conversion between the adsorption function and the desorption regeneration function of the entire device can be realized, and the adsorption saturation problem can be solved through desorption regeneration, which prolongs the service life of the device and improves the reliability of the device in use.

[0055] The working process of the air purification device is as follows: when the device is in the adsorption process, the malodorous gas passes through the adsorption matrix from the windward side. At this time, a relatively low-temperature heat exchange medium flows through the heat exchange component 200, reducing the temperature of the adsorption matrix. At this time, the malodorous gas is at a relatively higher temperature than the adsorption matrix. When the two meet, the molecules of the malodorous gas components with higher temperature come into contact with the relatively lower-temperature adsorption material and are quickly captured.

[0056] Since the higher the temperature, the better the volatility of the malodorous gas molecules, and the lower the temperature, the greater the adsorption capacity of the adsorption coating 110. Therefore, when the malodorous gas at a higher temperature passes through the adsorption coating 110 at a lower temperature, the malodorous gas molecules inside are fully captured and intercepted by the adsorption material in the adsorption coating 110, with sufficient adsorption and good adsorption effect, and the treated clean gas is discharged outwards.

[0057] As the malodorous gas molecules continuously accumulate on the adsorption coating 110 of the adsorption matrix, the adsorption performance of the adsorption coating 110 gradually decreases. At this time, regeneration treatment needs to be carried out on the adsorption coating 110 on the adsorption matrix. Reverse the air flow. At this time, the clean gas passes through the adsorption matrix from the leeward side. At this time, a relatively high-temperature medium flows through the heat exchange component 200, increasing the temperature of the adsorption matrix and the adsorption coating 110. The adsorbed malodorous gas gradually volatilizes as the temperature rises and is discharged into the outdoor environment to complete desorption.

[0058] In some embodiments, the adsorption matrix has thermal conductivity, so that its heat transfer and heat conduction effects are good, and heat exchange can be quickly carried out when the refrigerant of the heat exchange medium is introduced, so as to realize the rapid temperature adjustment of the adsorption coating 110.

[0059] In some embodiments, the adsorption matrix is a metal material such as metallic copper or aluminum, or a ceramic material such as alumina or silicon nitride, as long as it has good heat transfer performance.

[0060] In some embodiments of the present application, an air flow passage 120 is formed on the adsorption matrix for flowing the gas passing through the adsorption matrix.

[0061] In some embodiments of the present application, a plurality of the air flow passages 120 are provided, evenly distributed over and penetrating through the adsorption matrix, and the adsorption coating 110 is coated on the inner wall of the air flow passage 120.

[0062] The air flow passing through the adsorption matrix will pass through the air flow passage 120 penetrating through it. To achieve the adsorption and purification of the air flow passing through the adsorption matrix, the adsorption coating 110 is correspondingly coated on the inner wall of the air flow passage 120.

[0063] By arranging a plurality of the air flow passages 120 and evenly distributing them over the adsorption matrix, the contact area between the adsorption coating 110 and the air flow can be increased, so that the passing air flow can almost completely pass through the adsorption coating 110 in each air flow passage 120, ensuring sufficient adsorption and purification of the air flow and improving the adsorption and purification effect on the air flow.

[0064] In some embodiments, the air flow passage 120 is an air flow hole penetrating through the adsorption matrix along the air flow direction, and the shape of the air flow hole can be honeycomb-shaped, circular, square or polygonal.

[0065] In some embodiments of the present application, the adsorption matrix includes a plurality of matrix forming surfaces 133 for forming the surface of the adsorption matrix.

[0066] At least one matrix forming surface 133 is on the flow path of the air flow passing through the adsorption matrix, and the adsorption coating 110 is coated on the matrix forming surface 133 on the flow path.

[0067] When being coated, the adsorption coating 110 can be coated on the matrix forming surface 133, that is, on at least one surface of the adsorption matrix.

[0068] To ensure that the adsorption coating 110 can adsorb and purify the air flow passing through the adsorption matrix, the adsorption coating 110 should be coated on the matrix forming surface 133 on the air flow path, so as to ensure that the flowing air flow can pass through the adsorption coating 110 for adsorption and purification through the adsorption coating 110.

[0069] The substrate forming surface 133 on the air flow path may be one surface or multiple surfaces. When setting, the adsorption coating 110 is correspondingly coated on one surface or multiple surfaces.

[0070] In some embodiments of the present application, the heat exchange component 200 is arranged in contact with the outer surface of the adsorption substrate, used to contact the adsorption substrate, and directly or indirectly exchange heat with the adsorption coating 110 to adjust the temperature of the adsorption coating 110.

[0071] In some embodiments, the heat exchange component 200 is attached to the substrate forming surface 133 of the adsorption substrate coated with the adsorption coating 110. By directly attaching the heat exchange component 200 to the adsorption coating 110, when the heat exchange medium flows into the heat exchange component 200, it can directly exchange heat with the adsorption coating 110 to adjust the temperature of the adsorption coating 110.

[0072] In some embodiments, the heat exchange component 200 is attached to the substrate forming surface 133 of the adsorption substrate not coated with the adsorption coating 110. When the refrigerant is introduced into the heat exchange component 200, it exchanges heat with the adsorption substrate, and then is transferred to the adsorption coating 110 through the adsorption substrate to achieve temperature adjustment of the adsorption coating 110.

[0073] In some embodiments of the present application, the heat exchange component 200 is arranged inside the adsorption substrate, bent along the length and / or width direction of the adsorption substrate, and heat exchange inlet portions 220 and heat exchange outlet portions 230 are formed at both ends of the heat exchange component 200.

[0074] Through the bent heat exchange component 200, a bent heat exchange channel 210 can be formed inside the adsorption substrate, which can increase the contact area with the adsorption substrate and improve the heat exchange efficiency.

[0075] In some embodiments, the heat exchange component 200 is bent along the length direction of the adsorption substrate to form multiple connected bent segments, and heat exchange inlet portions 220 and heat exchange outlet portions 230 are formed at both ends thereof for the inflow and outflow of the refrigerant.

[0076] In some embodiments, the heat exchange component 200 is bent along the width direction of the adsorption substrate to form multiple bent segments connected end to end.

[0077] In some embodiments, the heat exchange component 200 is formed in two parts, one part is bent along the length direction of the adsorption substrate, and the other part is bent along the width direction of the adsorption substrate. The two parts are butt-connected, and heat exchange can also be achieved.

[0078] In some embodiments of the present application, the adsorption substrate includes:

[0079] The first adsorption frame 130 has an installation space 131 formed therein that penetrates through it.

[0080] And an adsorption member 132 connected inside the first adsorption frame 130, with the air flow channel 120 formed inside the adsorption member 132.

[0081] The adsorption member 132 is an adsorption substrate, which is sealed at the installation space 131 of the first adsorption frame 130, and is fixedly connected to the periphery of the first adsorption frame 130 around its perimeter.

[0082] The air flow channel 120 penetrates through the adsorption substrate, and the adsorption coating 110 is coated on the inner wall of the air flow channel 120 to adsorb and purify the air flow passing through the air flow channel 120.

[0083] By setting the adsorption matrix as the structure of the first adsorption frame 130 and a large-area adsorption substrate and arranging multiple air flow channels 120 on the adsorption substrate, the air flow can flow through the entire surface of the adsorption substrate, with a large contact area with the air flow and good adsorption effect.

[0084] In addition, the adsorption structure of assembling the adsorption substrate in the first adsorption frame 130 is simple and has low cost.

[0085] In some embodiments, the adsorption matrix includes a first adsorption frame 130 and an adsorption matrix assembled in the first adsorption frame 130. The adsorption matrix has a matrix forming surface 133 located on the air flow path of the adsorption matrix. The matrix forming surface 133 is the side surface of the adsorption matrix, and the adsorption coating 110 is coated on the side surface of the adsorption matrix.

[0086] In some embodiments, the matrix forming surface 133 is the surface of the adsorption matrix facing the air flow, and the adsorption coating 110 is coated on the surface of the adsorption matrix facing the air flow.

[0087] In some embodiments of the present application, the adsorption matrix includes:

[0088] A second adsorption frame 141, with an assembly space formed inside;

[0089] Adsorption sub-members 142, multiple in number, are assembled in the assembly space of the second adsorption frame 141. The multiple adsorption sub-members 142 are parallel to each other and connected, and an air flow channel 120 is formed between adjacent adsorption sub-members 142.

[0090] In some embodiments, the adsorption sub-members 142 are adsorption sub-fin sheets, multiple in number and parallel to each other. The two ends of the adsorption sub-fin sheets are respectively connected and fixed to the second adsorption frame 141, and the connection and support of the adsorption sub-fin sheets are realized through the second adsorption frame 141.

[0091] The air flow passage 120 formed between the adsorption fins facilitates the air flow through, and an adsorption coating 110 is provided on the adsorption fins.

[0092] In some embodiments, to connect the adsorption sub-components 142, the heat exchange component 200 is inserted through a plurality of the adsorption sub-components 142 to connect the plurality of adsorption sub-components 142 together.

[0093] In some embodiments, the heat exchange component 200 is a heat exchange tube.

[0094] In some embodiments, the adsorption coating 110 is provided on the heat exchange component 200.

[0095] The adsorption coating 110 is also provided on the heat exchange component 200, which can increase the area of the adsorption coating 110, increase the contact area with the air flow, and improve the adsorption effect.

[0096] In some embodiments of the present application, the air purification device includes: an auxiliary heating module, assembled on the adsorption component 132, for cooperating with the heat exchange medium introduced into the heat exchange component 200 to increase the temperature of the adsorption coating 110.

[0097] When it is necessary to raise the temperature of the adsorption coating 110 for desorption, if the refrigerant introduced into the heat exchange component 200 alone cannot make it reach the desorption temperature, the auxiliary heating module can be turned on to heat and raise the temperature of the adsorption coating 110 to ensure that the adsorption coating 110 can reach the desorption regeneration temperature for desorption.

[0098] In some embodiments, the auxiliary heating module includes a plurality of auxiliary heating elements 400, which are inserted inside the adsorption matrix and generate heat when powered on, so as to transfer the heat to the adsorption matrix and then to the adsorption coating 110 through the adsorption matrix to assist in heating the adsorption coating 110.

[0099] In some embodiments, the heat exchange channel 210 includes: a first heat exchange part 211, which is provided with two and is arranged oppositely, and is embedded inside the adsorption matrix and connected to the adsorption matrix;

[0100] The first heat exchange part 211 is a first heat exchange wall, which is provided with 2 and arranged oppositely. There is a spacing between the two first heat exchange parts 211, and they are respectively connected and fixed to the corresponding side of the adsorption matrix.

[0101] The adsorption matrix and the heat exchange component 200 can be integrally formed, or can be connected by welding or an expansion joint structure to ensure effective heat transfer between the two.

[0102] There are two second heat exchange parts 212, which are respectively connected to both ends of the two first heat exchange parts 211. At least part of the second heat exchange part 212 protrudes from the adsorption matrix, and an air flow guiding part 213 for guiding the air flow passing through the adsorption matrix is formed on the second heat exchange part 212.

[0103] The second heat exchange part 212 is a second heat exchange wall, which is bent and includes a first bent wall and a second bent wall.

[0104] The air flow guiding part 213 is a first guiding surface formed on the first bent wall and a second guiding surface formed on the second bent wall. Among them, the first guiding surface and the second guiding surface are inclined surfaces, and their inclination directions are opposite.

[0105] The first guiding surface and the second guiding surface are arranged facing the air flow passing through the adsorption matrix. When the air flow passes, it can guide the air flow. By setting the air flow guiding part 213, the resistance of the device can be greatly reduced, and thus the pressure loss can be reduced.

[0106] In some embodiments of the present application, there is also: an ultraviolet sterilization component 300, which is assembled on the adsorption matrix, and its light emission direction faces the adsorption coating 110.

[0107] The light emission direction of the ultraviolet sterilization component 300 faces the adsorption coating 110, which can ensure that the ultraviolet light emitted by it can irradiate the adsorption coating 110.

[0108] In some embodiments, an ultraviolet sterilization component 300 is provided on the first adsorption frame 130 at the windward side of the air purification device, and there is a distance between the ultraviolet sterilization component 300 and the adsorption member 132.

[0109] In some embodiments, the ultraviolet sterilization component 300 includes: a substrate and ultraviolet lamp beads. The ultraviolet lamp beads are LED lamp beads, and multiple are provided, and they are arranged in an alternating manner by LED lamp beads of different wavelengths, and the wavelength range is within 185 - 375 nm.

[0110] The ultraviolet sterilization component 300 directly irradiates the windward side surface of the adsorption matrix from the windward side. It mainly has two functions. On the one hand, ultraviolet light has a sterilization effect, which can prevent bacteria from growing on the surface of the adsorption matrix and the adsorption coating 110 after long-term use, and then cover the micropores on the adsorption coating 110, thus affecting the adsorption efficiency of odor.

[0111] On the other hand, ultraviolet light can undergo a photo-oxidation catalytic reaction with the photocatalyst on the surface of the adsorption coating 110, improving the purification effect.

[0112] In some embodiments of the present application, an air treatment device is proposed, including: a housing 510;

[0113] and a return air section 511 and an air outlet section 512 arranged on the housing 510;

[0114] A heat exchange air duct 520 for circulating gas, and the gas exchanges heat within the heat exchange air duct 520;

[0115] A air supply device 530 is arranged within the heat exchange air duct 520 for driving the gas to flow within the heat exchange air duct 520;

[0116] An air purification device is assembled in the return air section 511, the air outlet section 512 or the heat exchange air duct 520.

[0117] When in use, the air purification device can be arranged at the return air section 511 for adsorption purification, or can be arranged at the air outlet section 512 for adsorption purification or arranged within the heat exchange air duct 520 for adsorption purification.

[0118] In some embodiments, the air purification device is arranged at the return air section 511, and the air treatment device has an adsorption operation mode and a desorption operation mode.

[0119] When the air treatment device is in the adsorption operation mode, the air flow is inhaled from the return air section 511 into the interior of the heat exchange air duct 520 through the air supply device 530, is adsorbed and purified by the air purification device at the return air section 511, and then is sent out from the air outlet section 512.

[0120] In this mode, the air supply device 530 rotates in a first direction, and a refrigerant with a relatively low temperature introduced into the heat exchange channel 210 of the air purification device exchanges heat with the adsorption coating 110 to reduce the temperature of the adsorption coating 110 and improve the adsorption effect of the adsorption coating 110;

[0121] When the air treatment device is in the desorption operation mode, the air supply device 530 rotates in a second direction, and the second direction is opposite to the first direction. At this time, a refrigerant with a relatively high temperature introduced into the interior of the heat exchange channel 210 exchanges heat with the adsorption coating 110 to increase the temperature of the adsorption coating 110. The adsorption coating 110 is desorbed and regenerated due to the increased temperature, and the waste gas discharged during desorption regeneration can be discharged to the outside through the reverse rotation of the air supply device 530 in cooperation.

[0122] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.
