Description

Technical Field

[0001] The invention relates to the technical field of dehumidification wheels, and in particular to a dehumidification structure and a dehumidification wheel. Background Art

[0002] The main core component of the rotary adsorption dehumidifier is the dehumidification wheel, which is made of glass fiber and heat-resistant ceramic materials as the internal support carrier of the wheel, and high-efficiency moisture-absorbing medium materials (such as high-efficiency silica gel). In this way, the high-efficiency moisture absorbent plus the honeycomb structure of the wheel itself not only ensures a huge surface area of ​​contact between the wheel and the air, but also improves the moisture absorption efficiency and moisture absorption capacity of the wheel; the wheel can be cleaned by gas blowing to remove some mechanical pollutants on the surface of the wheel, such as dust, oil, etc.

[0003] The dehumidification wheel is divided into a processing area and a regeneration area by a sealing system inside the dehumidification section. The dehumidification wheel rotates slowly at a speed of 8-10 revolutions per hour to ensure that the entire dehumidification is a continuous process. When the treated air passes through the treatment area of ​​the wheel, the water vapor in it is adsorbed by the hygroscopic medium in the wheel. At the same time, the water vapor undergoes a phase change and releases latent heat. The wheel also gradually tends to saturation due to the absorption of a certain amount of moisture; at this time, the treated air becomes dry and hot air due to the reduction of its own moisture and the release of latent heat. At the same time, in the regeneration area, the other air first passes through the regeneration heater, becomes high-temperature air (generally 100-140℃) and passes through the saturated wheel after moisture absorption, so that the adsorbed moisture in the wheel evaporates, thereby restoring the dehumidification capacity of the wheel; at the same time, the regeneration air becomes humid air due to the evaporation of moisture; then, the humid air is discharged to the outside through the regeneration fan.

[0004] In practice, although inorganic substances such as silica gel have a large moisture absorption capacity, they will also expand after absorbing moisture. Usually, in order to avoid excessive expansion after moisture absorption and affect the dehumidification effect or avoid damage to the dehumidification wheel and thus affect the life of the equipment, it is generally necessary to control their moisture absorption. At present, changing the wheel speed is often used to avoid excessive expansion of the hygroscopic medium, but this method has limited improvement effect and has high requirements for the motor. Summary of the invention

[0005] The object of the present invention is to overcome one or more deficiencies in the prior art and to provide an improved dehumidification structure which can effectively utilize its expansion characteristics to increase moisture absorption performance and can also restrict its expansion to avoid excessive expansion.

[0011] In the present invention, the moisture absorbing medium that has expanded after absorbing water radially compresses the rebound connecting column, thereby expanding the thickness space to obtain a larger water storage space, and providing a rapid recovery capability through the rebound connecting column.

[0012] In some embodiments of the present invention, the resilient connecting column is arranged in parallel with the fixed connecting column.

[0013] In some embodiments of the present invention, the resilient connecting columns are arranged parallel to each other.

[0014] According to some preferred aspects of the present invention, the first connection component includes two groups of sub-connection components sequentially arranged along the thickness direction of the hygroscopic medium layer, and the two groups of sub-connection components are symmetrically arranged along the hygroscopic medium layer.

[0015] According to some preferred aspects of the present invention, each group of the sub-connection components includes n fixed connection columns arranged in parallel with each other, and the resilient connection column is inserted between two adjacent fixed connection columns.

[0016] In some embodiments of the present invention, the sub-connection assembly is divided into x groups of fixed connection column arrays by a plurality of the resilient connection columns, each group of the fixed connection column array includes y fixed connection columns arranged in parallel, n is the product of x and y, and x and y are both greater than or equal to 2.

[0017] According to some preferred aspects of the present invention, the fixed connecting column is made of graphene and / or thermally conductive plastic.

[0018] According to some preferred aspects of the present invention, the hygroscopic material of the hygroscopic medium layer is silica gel and / or zeolite molecular sieve.

[0019] According to some preferred aspects of the present invention, the hygroscopic medium layer is provided with a plurality of openings penetrating along its thickness direction, the number of the openings corresponds one-to-one to the number of the resilient connecting columns, the resilient connecting columns are inserted in the openings, and the difference between the outer diameter of the resilient connecting columns and the size of the openings is within 1%, for example, can be within 0.5%, and can further be the same.

[0020] According to some preferred aspects of the present invention, a water groove is provided on the surface of the resilient connecting column, and the water groove is used to connect two side surfaces of the moisture absorbing medium layer along its thickness direction.

[0021] According to some preferred aspects of the present invention, the resilient connecting column is a hollow structure.

[0022] According to some preferred aspects of the present invention, the material of the resilient connecting column is rubber.

[0024] Another technical solution provided by the present invention is a dehumidification wheel, which includes a supporting carrier and a hygroscopic layer loaded on the supporting carrier, and the hygroscopic layer includes the dehumidification structure described above.

[0025] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0026] Based on the defects of the over-expansion of the hygroscopic medium in the prior art when used in the rotating wheel, or the improved method used to avoid its over-expansion, the inventor of the present invention has innovatively proposed after a large number of experimental studies: by arranging fixed connecting columns between the sericin layer and the hygroscopic medium layer, the distance between the sericin layer and the hygroscopic medium layer can be guaranteed, and the detachment of the sericin layer can be avoided to affect the overall hygroscopic effect; at the same time, the sericin layers are respectively connected to the two sides of the hygroscopic medium layer, and the sericin layers on both sides cover and surround the hygroscopic medium, which can filter impurities and store a certain amount of moisture. A number of fixed connecting columns are distributed between the sericin layer and the hygroscopic medium layer, so that the surface of the dehumidifying layer is smooth as a whole, and the expansion effect after moisture absorption is controllable; in addition, on the one hand, through the swelling effect of the sericin layer after absorbing water, the hygroscopic layer as a whole can play a role of water storage after absorbing enough moisture, thereby cooperating with the hygroscopic medium to expand the threshold value of moisture absorption. On the other hand, water vapor conducts water to the hygroscopic medium layer through the sericin layer on one side. The hygroscopic medium layer expands after absorbing moisture, and the tension in the width direction causes the rebound connecting column to be radially squeezed, so that it deforms and stretches in the length direction, thereby pushing the sericin layer outward, and indirectly pulling the hygroscopic medium to stretch in the thickness direction, expanding the hygroscopic space, and improving the adsorption performance; further, when the absorbed moisture is saturated, it enters the regeneration zone, and while the high-temperature gas is used to remove moisture, the deformation recovery force of the rebound connecting column itself pulls the sericin layers pushed away on both sides to retract, further increasing the moisture removal rate, thereby improving the regeneration efficiency of the dehumidification wheel, especially, because the fixed connecting column can conduct heat, the fixed connecting column can not only play a role in supporting and connecting force conduction, but also can effectively heat the hygroscopic medium in the regeneration zone through its good thermal conductivity, which is beneficial to desorption regeneration and lowering the desorption temperature.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, the reference to "embodiment", "one embodiment" or "other embodiments" means that the specific features, structures or characteristics described in conjunction with the embodiment are included in at least some embodiments, but not necessarily all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it is necessary to understand that the terms "center", "longitudinal", "lateral", "up", "down", "vertical", "horizontal", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0031] The present invention aims to provide a high-adsorption dehumidification structure for a dehumidification wheel, which expands the thickness space by radially compressing the rebound connection column through the moisture-absorbing medium that expands after absorbing water, thereby obtaining a larger water storage space, and provides a rapid recovery capability through the rebound connection column. It can effectively utilize its expansion characteristics to increase the moisture absorption performance, and can also restrict its expansion to avoid excessive expansion.

[0032] See also Figure 1 As shown, this example provides a dehumidification structure, which includes a hygroscopic medium layer 1, a sericin layer 2 surrounding the outer peripheral side of the hygroscopic medium layer 1, a first connecting component and a second connecting component with elastic recovery ability; the first connecting component includes a plurality of fixed connecting columns 3 capable of heat conduction, and both ends of each fixed connecting column 3 are respectively connected to the hygroscopic medium layer 1 and the sericin layer 2, so that the distance between the sericin layer 2 and the hygroscopic medium layer 1 can be ensured, and the detachment of the sericin layer 2 is avoided to affect the overall hygroscopic effect; the second connecting component includes a plurality of resilient connecting columns 4; each resilient connecting column 4 passes through the hygroscopic medium layer 1 in the thickness direction of the hygroscopic medium layer 1, and both ends are respectively connected to the corresponding sericin layers 2 on both sides, the sericin layers 2 on both sides cover and surround the hygroscopic medium layer 1, which can filter impurities, and can store a certain amount of moisture itself, and a plurality of fixed connecting columns 3 can be regularly and densely distributed between the sericin layer 2 and the hygroscopic medium layer 1, which is more conducive to making the surface of the dehumidification layer smooth as a whole, and the expansion effect after moisture absorption is controllable.

[0033] The resilient connecting column 4 passes through the hygroscopic medium layer 1 in the thickness direction, and its two ends are respectively connected to the sericin layers 2 on both sides. A plurality of resilient connecting columns 4 can be distributed at equal intervals in the width direction of the hygroscopic medium layer 1. The resilient connecting column 4 can ensure the distance between the sericin layer 2 and the hygroscopic medium layer 1, and avoid adhesion that causes excessive moisture in the hygroscopic medium layer 1 to flow to the sericin layer 2, thereby avoiding moisture outflow.

[0034] In this example, the resilient connecting pillars 4 are arranged in parallel with the fixed connecting pillars 3 , and the resilient connecting pillars 4 are arranged in parallel with each other.

[0035] The first connection component includes two groups of sub-connection components arranged in sequence along the thickness direction of the hygroscopic medium layer 1, and the aforementioned two groups of sub-connection components are symmetrically arranged along the hygroscopic medium layer 1; each group of sub-connection components includes n fixed connection columns 3 arranged in parallel with each other, and the rebound connection column 4 is inserted between two adjacent fixed connection columns 3. Further, the sub-connection components are divided into x groups of fixed connection column arrays by multiple rebound connection columns 4, and each group of fixed connection column arrays includes y fixed connection columns 3 arranged in parallel, n is the product of x and y, and x and y are both greater than or equal to 2.

[0036] The material of the fixed connecting column 3 is graphene and / or thermally conductive plastic. Preferably, graphene material can be used. The strength and toughness of graphene can enhance and maintain the mechanical strength and stability of the dehumidification wheel; its high specific surface area and molecular adsorption capacity can effectively adsorb water molecules in the air, thereby improving the dehumidification efficiency of the dehumidification wheel; in addition, since the sericin layer 2 connected to the fixed connecting column needs to play a certain filtering role, the graphene can effectively inhibit the growth of bacteria and mold in the dehumidification wheel (it is generally believed that when graphene contacts the bacterial cell membrane, it will produce charge transfer or reactive oxygen (ROS), triggering free radical reactions, destroying the membrane structure and important biological macromolecules of bacteria), thereby ensuring the long-term healthy operation of the dehumidification wheel. In other embodiments, odorless and non-toxic lightweight materials such as polypropylene can be used, and it is only necessary to ensure that it can withstand the high temperature in the regeneration zone and will not emit toxic gases. In addition, graphene can not only play a supporting and connecting force conduction role, but also can effectively heat the hygroscopic medium 1 in the regeneration zone through its good thermal conductivity, thereby performing desorption regeneration, which is beneficial to reducing the desorption temperature.

[0037] The hygroscopic material of the hygroscopic medium layer 1 is silica gel and / or zeolite molecular sieve. In this example, the hygroscopic medium of the hygroscopic medium layer 1 preferably adopts silica gel with a microporous structure. The hygroscopic medium layer 1 is provided with a plurality of openings penetrating along its thickness direction. The number of openings corresponds to the number of resilient connecting columns 4. The resilient connecting columns 4 are inserted into the openings, and the difference between the outer diameter of the resilient connecting columns 4 and the size of the openings is within 1%, for example, within 0.5%, and can be further the same. A water trough 41 is provided on the surface of the resilient connecting column 4. The water trough 41 is used to connect the two sides of the hygroscopic medium layer 1 along its thickness direction. The water trough 41 can guide moisture from one side of the hygroscopic medium 1 to the other side end face without affecting the deformation of the hygroscopic medium 1, thereby improving the moisture absorption rate of the hygroscopic medium 1.

[0038] In this example, the rebound connecting column is a hollow structure, and the material of the rebound connecting column is rubber. In its embodiment, the rebound connecting column 4 can also be made of other other light elastic materials.

[0039] Since the rebound connecting column 4 has a rebound characteristic, when the rebound connecting column 4 is subjected to a compressive force in the radial direction, it will elongate in the length direction. This is because the rubber material will store elastic energy when it is compressed by an external force, and then release it when the external force disappears or at a position where the external force is weaker; further, the rebound connecting column 4 has an internal hollow structure, that is, the setting of a hollow structure can improve its deformation ability in the length direction after being compressed.

[0040] At the same time, although the hygroscopic medium layer 1 will naturally expand in the thickness direction after absorbing moisture, based on the volume of the dehumidification wheel and the large-area end surface structure, its relatively small natural expansion in the thickness direction is bound to be far less than the push-pull effect of the large-area end surface width direction. Therefore, the push-pull effect of the hygroscopic medium layer 1 in the end surface width direction and inward is converted into expansion in the thickness of the hygroscopic medium layer 1 through the rebound connecting column 4, which can effectively expand the hygroscopic space, thereby improving the adsorption performance. When the moisture is absorbed and saturated, it enters the regeneration zone. While the high-temperature gas is used to remove moisture, the deformation recovery force of the rebound connecting column 4 itself pulls the sericin layer 2 pushed away on both sides to retract, further improving the moisture removal rate, thereby improving the regeneration efficiency of the dehumidification wheel.

[0041] In this example, the sericin layer 2 is composed of silk nanofibers. The silk nanofibers can be prepared according to the prior art or commercially available. For example, preferably, silk is prepared by electrostatic spinning, which has good mechanical properties, water storage capacity and good water vapor permeability. The silk nanofibers have a high specific surface area, so they can absorb a large amount of water and have a strong water storage capacity.

[0042] For example, the preparation can be carried out with reference to CN114457447B. Alternatively, the preparation can be carried out in the following manner: silk is boiled and rinsed to obtain silk fibroin, the silk fibroin is dissolved in a lithium bromide solution, the silk fibroin is dialyzed and filtered after complete dissolution, freeze-dried to obtain freeze-dried silk fibroin, the freeze-dried silk fibroin is dissolved in a formic acid solution, a silk strand protein solution is prepared by magnetic stirring, and a silk fibroin nanofiber surface layer is prepared by electrostatic spinning.

[0043] In other embodiments, the silk nanofibers can also be mixed with polyurethane, epoxy resin, etc. to prepare tear-resistant composite fiber materials.

[0044] At the same time, it should be noted that, generally, the temperature in the regeneration zone is about 140°C. Silk nanofibers can maintain their structure and performance at a high temperature of 300°C, and will only begin to decompose at a high temperature of about 400°C. The structure and properties will change and the performance will decrease. Therefore, silk nanofibers meet the application environment of the dehumidification wheel.

[0045] The preparation method of the dehumidification structure of this example comprises the following steps:

[0046] (1) preparing a dehumidifying medium (hygroscopic medium) into a rotating wheel body according to a mold, and reserving openings;

[0047] (2) penetrating the resilient connecting column 4 on the surface of the rotor body and bonding the fixed connecting column 3 so that the end surfaces of the fixed connecting column 3 and the resilient connecting column 4 are flush;

[0048] (3) The sericin layer 2 is bonded to the resilient connecting column 4 and the corresponding side end surface of the fixing component 3 .

[0049] It should be noted that the connection between the sericin layer 2 and the fixed connection column 3, such as a graphene column, can be achieved by bonding with an active agent or by hot pressing.

[0050] Specifically, the following method can be used: put the graphene column and the sericin layer together, and then heat and fuse them together with a hot melt glue gun or a similar tool.

[0051] or chemical bonding: such as coating the surface of the graphene pillars with appropriate chemicals to react with the chemical bonds on the sericin layer, thereby fixing them together, or by preparing graphene pillars with surfaces coated with active agents to adsorb them on the sericin layer.

[0052] There are two types of surfactants that can be used: anionic surfactants and cationic surfactants. Anionic surfactants have good wettability and foaming properties, but the bonding effect on silk fibers is not very good. Cationic surfactants can be completely consistent with hydrophilic silk fibers; cationic surfactants can be selected from acrylate cationic surfactants, alcohol amine cationic surfactants, tetradecylamine cationic surfactants, etc. The above cationic surfactants have good adhesion and hydrophilicity, and can effectively fix the graphene column and the sericin layer together.

[0053] Or put the graphene pillars and sericin layers together, then pressurize them with high pressure and temperature to cause a certain degree of melting on the surface, and then let them cool and solidify together.

[0054] As an optional embodiment, the edge of the dehumidification structure is fixedly connected to the inner wall of the dehumidification wheel body, and the sericin layer 2 is preferably annularly and tightly connected to the wheel body, such as by gluing, rather than multi-point connection. The edge of the sericin layer 2 is fixed, which can limit its freedom of swelling, thereby controlling the swelling effect and avoiding excessive free expansion that causes irreversible changes in its performance.

[0055] This example also provides a dehumidification wheel, which includes a support carrier and a hygroscopic layer loaded on the support carrier, and the hygroscopic layer includes the above-mentioned dehumidification structure.

[0056] In summary, the present invention innovatively arranges fixed connecting columns between the sericin layer and the hygroscopic medium layer, so that the distance between the sericin layer and the hygroscopic medium layer can be ensured, thereby preventing the detachment of the sericin layer from affecting the overall hygroscopic effect. At the same time, the sericin layers are respectively connected to the two sides of the hygroscopic medium layer. The sericin layers on both sides cover and surround the hygroscopic medium, which can filter out impurities and store a certain amount of moisture. A number of fixed connecting columns are distributed between the sericin layer and the hygroscopic medium layer, so that the surface of the dehumidifying layer is smooth as a whole, and the expansion effect after moisture absorption is controllable. In addition, on the one hand, through the swelling effect of the sericin layer after absorbing water, the hygroscopic layer as a whole can store water after absorbing enough water, thereby cooperating with the hygroscopic medium to expand the threshold value of moisture absorption. On the other hand, the water vapor conducts water to the hygroscopic medium layer through the sericin layer on one side, and the hygroscopic medium layer The hygroscopic medium expands after absorbing moisture, wherein the tension in the width direction causes the resilient connecting column to be radially squeezed, thereby deforming and elongating in the length direction, thereby pushing the sericin layer outward, and indirectly pulling the hygroscopic medium to stretch in the thickness direction, expanding the hygroscopic space, and improving the adsorption performance; further, when the moisture is absorbed and saturated, it enters the regeneration zone, and while the high-temperature gas is used to remove moisture, the deformation recovery force of the resilient connecting column itself pulls the sericin layers pushed away on both sides to retract, further increasing the moisture removal rate, thereby improving the regeneration efficiency of the dehumidification wheel, in particular, because the fixed connecting column can conduct heat, the fixed connecting column can not only play a role in supporting and connecting force conduction, but also can effectively heat the hygroscopic medium in the regeneration zone through its good thermal conductivity, which is beneficial to desorption regeneration and lowering the desorption temperature.
