Description

Technical Field

[0001] The invention relates to the technical field of air treatment equipment, and in particular to a design scheme of a novel rotary dehumidifier aimed at the efficiency and regeneration synchronization problems faced by a traditional rotary dehumidifier when treating high-humidity air. Background Art

[0002] In the field of traditional air treatment equipment, rotary dehumidifiers are a common dehumidification equipment and are widely used in various occasions where humidity needs to be controlled. However, with the development of technology and the improvement of people's requirements for air quality, the problems faced by traditional rotary dehumidifiers in handling high-humidity air have gradually become prominent.

[0003] First, traditional rotary dehumidifiers usually use a single rotor design, which often results in low dehumidification efficiency when dealing with high-humidity air due to the limited moisture absorption capacity of the rotor. Especially in situations where continuous and efficient dehumidification is required, such as pharmaceuticals, food processing, and electronic manufacturing, the single rotor design often cannot meet production needs, resulting in reduced production efficiency and affected product quality.

[0004] Secondly, traditional rotary dehumidifiers have the problem of residual moisture during the regeneration process. Regeneration is the key link for rotary dehumidifiers to maintain efficient dehumidification performance. However, due to the limitations of the single rotor design, the moisture in the desiccant is often not completely removed during the regeneration process, resulting in incomplete regeneration. This not only affects the subsequent dehumidification performance, but may also cause the desiccant to fail and shorten the service life of the equipment.

[0005] In addition, traditional dehumidifiers lack flexibility in structural layout, making it difficult to achieve compact and efficient space utilization. Traditional dehumidifiers usually adopt a fixed structural layout and cannot be adjusted and optimized according to actual needs. This not only increases the footprint of the equipment, but also increases energy consumption, which is not conducive to energy conservation, emission reduction and sustainable development.

[0006] In summary, the problems of efficiency and regeneration synchronization, inflexible structural layout and other issues faced by traditional rotary dehumidifiers when processing high-humidity air have seriously restricted their effectiveness in practical applications. Therefore, the development of a new type of rotary dehumidifier to solve the above problems and improve dehumidification efficiency and regeneration effect has become an urgent need in the current field of air treatment equipment. Summary of the invention

[0007] The present invention provides a novel rotary dehumidifier, which significantly improves the dehumidification efficiency and regeneration effect by adopting a double-rotor mechanism overlapping design.

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: a novel rotary dehumidifier, comprising a dehumidification component, the dehumidification component comprising two partially overlapping rotary wheel mechanisms, and two partitions respectively arranged on both sides of the rotary wheel mechanisms and arranged along the edges of the overlapping areas of the two rotary wheel mechanisms, the area of ​​the rotary wheel mechanism located outside the partition is a processing area, and the area located inside the partition is a regeneration area, the rotary wheel mechanism comprises a wheel frame and outer frames coaxially arranged on both sides of the wheel frame, wherein a desiccant is arranged in the wheel frame, and a plurality of baffles parallel to each other and covering the entire outer frame are arranged at intervals in the two outer frames; It also includes a motor for driving the two rotating wheel mechanisms to rotate, a processing fan arranged on the processing air output end, a heating mechanism arranged on the regeneration air input end, and a regeneration fan arranged on the regeneration air output end; When the two rotating wheel mechanisms rotate until the baffles on the surfaces close to each other are parallel to each other, the positions of the baffles on the two wheels complement each other to form a sealing area.

[0009] In some embodiments, the desiccant is a mixture of one or more of silica gel, lithium chloride, molecular sieve or activated carbon, and is uniformly filled in the wheel frame in the form of particles, sheets or fibers.

[0010] In some embodiments, a filtering mechanism is provided on the input ends of the processed air and the regenerated air, and the filtering mechanism includes a primary filter and a medium-efficiency filter.

[0011] In some embodiments, a surface cooler is also included, and the surface cooler is arranged between the process air input end and the dehumidification component.

[0012] In some embodiments, the baffles on both sides of the same rotating wheel mechanism are arranged in a staggered manner, and the intervals between the baffles on both sides are not opposite to each other, that is, the position of the baffle on one side is vacant on the other side, forming a staggered arrangement pattern.

[0013] In some embodiments, the partition is made of one or more materials selected from stainless steel, aluminum alloy or high temperature resistant plastic.

[0014] In some embodiments, the two rotating wheel mechanisms rotate in opposite directions.

[0015] Compared with the prior art, the present invention has the following beneficial effects: By adopting the overlapping design of double rotor mechanisms, the present invention significantly improves the dehumidification efficiency and regeneration effect. Specifically, this design realizes the effective diversion of humid air, reducing the dehumidification burden of the single-sided rotor mechanism; the overlapping regeneration area realizes the simultaneous drying of the two rotor mechanisms, greatly improving the compactness and operation efficiency of the equipment; the cleverly designed baffle structure and the rotor mechanism rotation mechanism effectively solve the problem of asynchronous drying in the regeneration area, ensuring the thoroughness and synchronization of the regeneration process, thereby improving the overall dehumidification performance. In addition, the selection of desiccant, the setting of the filter mechanism, the design of the surface cooler, and the optimization of the partition material and the rotation direction of the rotor mechanism further enhance the practicality and performance of the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-5 As shown, this embodiment provides a novel rotary dehumidifier, including a dehumidification component 1, the dehumidification component 1 includes two partially overlapping rotary wheel mechanisms 101, and two partitions 102 respectively arranged on both sides of the rotary wheel mechanisms 101 and arranged along the edges of the overlapping regions of the two rotary wheel mechanisms 101, the region of the rotary wheel mechanism 101 located outside the partition 102 is a processing region, and the region located inside the partition 102 is a regeneration region, the rotary wheel mechanism 101 includes a wheel frame 1011 and outer frames 1013 coaxially arranged on both sides of the wheel frame 1011, wherein a desiccant 1012 is arranged in the wheel frame 1011, and a plurality of baffles 1014 parallel to each other and covering the entire outer frame 1013 are arranged at intervals in both outer frames 1013; It also includes a motor 2 for driving the two wheel mechanisms 101 to rotate, a processing fan 3 arranged on the processing air output end, a heating mechanism 4 arranged on the regeneration air input end and a regeneration fan 5 arranged on the regeneration air output end; when the two wheel mechanisms 101 rotate until the baffle bars 1014 on their mutually adjacent surfaces are parallel to each other, at this time, the baffle bars 1014 on the two are complementary in position to form a sealing area, these baffle bars 1014 not only enhance the structural strength, but also provide a basis for realizing a specific airflow channel.

[0023] During operation, the motor 2 drives the two wheel mechanisms 101 to rotate synchronously. The processing area is responsible for absorbing moisture in the humid air, and the regeneration area is used to dry the wheel after moisture absorption. The humid air is introduced through the processing fan 3 and is divided into two parts and guided through the two processing areas to achieve efficient dehumidification. At the same time, the dry hot air generated by the heating mechanism 4 is sent to the overlapping regeneration area through the regeneration fan 5 to regenerate the saturated wheel.

[0024] The two rotary mechanisms 101 of the present invention are arranged in an overlapping manner, forming an overlapping area and two non-overlapping areas on both sides of the overlapping area, thereby forming two processing areas and an overlapping regeneration area, so that the wet air can be divided into two and transmitted through the two processing areas to achieve the purpose of dehumidification. Such diversion reduces the dehumidification burden of the single-side area, and because the regeneration areas of the two rotary mechanisms 101 are overlapped, the two rotary mechanisms can be dried at one time, and the overall structure is compact and efficient; Of the two rotary mechanisms 101 of the present invention, one is close to the heating mechanism 4 and the rotary mechanism 101 can directly receive dry hot air, and the other is close to the regeneration fan 5, and there is another rotary mechanism 101 between it and the heating mechanism 4. In addition, the regeneration areas of the two rotary mechanisms 101 overlap with each other. Therefore, it is easier for moisture to remain in the rotary mechanism 101 close to the regeneration fan 5, resulting in asynchronous drying of the regeneration areas of the two rotary mechanisms 101. In this regard, in the present invention, when the two rotary mechanisms 101 rotate until the baffle bars 1014 on their surfaces close to each other are parallel to each other, the baffle bars 1014 on the two are complementary to each other to form a sealing area. Therefore, when the two wheel mechanisms 101 rotate until the bars 1014 on the surfaces close to each other are parallel to each other, the regeneration air cannot pass through the regeneration area. Since the regeneration fan 5 is still working at this time, a negative pressure will be formed in the regeneration area of ​​the wheel mechanism 101 close to the regeneration fan 5. With the subsequent continuous operation of the wheel mechanism 101, the residual moisture in the regeneration area can be effectively extracted and accelerated during the recovery of the negative pressure, thereby ensuring that the drying process of the regeneration area of ​​the two wheel mechanisms 101 remains synchronized. In general, when the two wheel mechanisms 101 rotate until the bars 1014 on the surfaces close to each other are parallel, the positions of these bars 1014 complement each other to form a temporary sealing area. This utilizes the dynamic characteristics of the wheel rotation, so that at a specific moment, the regeneration air cannot penetrate the regeneration area, and the continuous operation of the regeneration fan 5 generates negative pressure in this area. As the wheel continues to rotate, the negative pressure gradually recovers. During this period, under the action of air pressure, the hot air flow rate passing through the regeneration area of ​​the wheel mechanism 101 close to the regeneration fan 5 will be significantly accelerated. This process effectively promotes the rapid discharge of residual moisture and ensures that the regeneration areas of the two wheel mechanisms 101 can maintain a synchronous and thorough dry state, thereby achieving efficient and stable dehumidification operations.

[0025] In summary, the present invention significantly improves the dehumidification efficiency and regeneration effect by adopting a double-wheel overlapping design. Specifically, this design not only achieves effective diversion of humid air and reduces the dehumidification burden of the single-sided wheel, but also achieves simultaneous drying of the two wheels through overlapping regeneration areas, greatly improving the compactness and operating efficiency of the equipment. More importantly, the present invention effectively solves the problem of asynchronous drying in the regeneration area through the cleverly designed baffle 1014 structure and wheel rotation mechanism, ensuring the thoroughness and synchronization of the regeneration process, thereby improving the overall dehumidification performance.

[0026] In some embodiments, the desiccant 1012 is specifically a mixture of one or more of silica gel, lithium chloride, molecular sieve or activated carbon, and the desiccant 1012 is uniformly filled in the wheel frame 1011 in the form of particles, sheets or fibers, ensuring efficient moisture absorption while facilitating the rapid release and discharge of moisture during the regeneration process.

[0027] These materials are widely used due to their excellent hygroscopic properties and regeneration capabilities. Silica gel has high hygroscopicity and chemical stability, and can maintain high efficiency in moisture absorption over a wide temperature range; lithium chloride has strong hygroscopicity and a fast hygroscopicity rate, and is particularly suitable for high humidity environments; molecular sieves can selectively absorb moisture and are easy to regenerate due to their uniform pore size distribution and high specific surface area; activated carbon not only has good hygroscopic properties, but can also absorb other impurities in the air to improve air quality.

[0028] By uniformly filling the wheel frame 1011 with the granular, flake or fibrous forms of the hygroscopic agents 1012, the space in the wheel frame 1011 can be maximized, and the contact area between the hygroscopic agents 1012 and the wet air can be increased, thereby improving the moisture absorption efficiency. At the same time, this form design is also conducive to the uniform transfer of heat during the regeneration process, so that the hygroscopic agents 1012 can quickly release and discharge the absorbed moisture, thereby improving the regeneration efficiency.

[0029] In addition, the mixed use of multiple desiccant agents 1012 can combine the advantages of each material to achieve a wider range of humidity adaptability and higher dehumidification efficiency. For example, the mixed use of silica gel and lithium chloride can improve the temperature resistance of the equipment while ensuring efficient moisture absorption; the mixed use of molecular sieve and activated carbon can purify other pollutants in the air while dehumidifying.

[0030] In some embodiments, a filtering mechanism is provided at the input end of the processed air and the regenerated air. The filtering mechanism includes a primary filter and a medium filter. The primary filter is used to block large particles and dust, and the medium filter further filters fine particles to ensure the cleanliness of the air entering the dehumidifier.

[0031] Specifically, the primary filter can block large particles and dust in the air, such as hair, dandruff, fiber, etc., while the medium-efficiency filter can further filter out fine particles, such as pollen, bacteria, viruses, etc. In this way, the air entering the dehumidifier is effectively purified, thereby improving the quality of the output air and providing users with a healthier and more comfortable indoor environment. If the particles and dust in the air directly enter the dehumidifier, they may adhere to the internal components such as the rotor mechanism 101, the desiccant 1012, and the fan, resulting in a decrease in dehumidification efficiency and even equipment failure. By setting up a filtering mechanism, these pollutants can be effectively blocked to protect the cleanliness and normal operation of the internal components of the dehumidifier.

[0032] In some embodiments, a surface cooler is also included. The surface cooler is arranged between the processed air input end and the dehumidification component 1, and is used to pre-cool the humid air entering the dehumidifier to reduce the air temperature, thereby improving the dehumidification efficiency.

[0033] The surface cooler lowers the temperature of the air by pre-cooling the humid air entering the dehumidifier. As the temperature decreases, the water vapor in the air is more likely to condense, thereby increasing the dehumidifier's ability to remove moisture. This design enables the dehumidifier to achieve a higher dehumidification efficiency when treating air with the same humidity. Moreover, after the air is pre-cooled by the surface cooler, part of the water vapor in the air has been condensed and discharged, which reduces the dehumidification burden of the rotary mechanism 101. The rotary mechanism 101 can focus more on processing the remaining moisture, thereby improving the overall dehumidification effect and the operating efficiency of the equipment.

[0034] In some embodiments, the baffles 1014 on both sides of the same rotary mechanism 101 are arranged in a staggered manner, and the intervals between the baffles 1014 on both sides are not opposite to each other, that is, the position of the baffle 1014 on one side is vacant on the other side, forming a staggered arrangement pattern. The staggered baffles 1014 force the humid air and the regenerated air to flow more tortuously along these complex air flow channels when passing through the rotary mechanism 101. This design increases the transmission time of the air in the rotary mechanism 101, allowing the air and the desiccant 1012 to have more sufficient contact and exchange opportunities, thereby improving the efficiency of dehumidification and regeneration.

[0035] In some embodiments, the partition 102 is made of one or more of stainless steel, aluminum alloy or high temperature resistant plastic. In the present invention, the partition 102 is a key component for separating the processing area and the regeneration area, and the selection of its material has an important influence on the overall performance and service life of the device. Therefore, the above-mentioned high-strength, high temperature resistant and good airtight materials are selected as the partition 102.

[0036] In some embodiments, Figure 1As shown, the rotation directions of the two rotary mechanisms 101 are opposite, that is, when one rotary mechanism 101 rotates clockwise, the other rotary mechanism 101 rotates counterclockwise. The two rotary mechanisms 101 rotating in opposite directions form a dynamic heat exchange environment in the regeneration area. When the hot air passes through the regeneration area, it will be subjected to the shear force and disturbance generated by the rotation of the two rotary mechanisms 101, which accelerates the heat transfer process between the hot air and the desiccant 1012. In addition, the rotation in opposite directions also helps to form a more complex airflow channel, increasing the contact time and area between the hot air and the desiccant 1012, which shortens the regeneration time, improves the regeneration efficiency, and helps to reduce the residual moisture in the regeneration area.

[0037] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
