Description

Technical Field

[0001] This utility model relates to the field of dehumidifier technology, specifically to a rotary dehumidifier duct structure. Background Technology

[0002] In numerous fields such as industrial production, warehousing and logistics, electronics manufacturing, food processing, and precision instrument rooms, precise control of air humidity is a key factor in ensuring production quality, product storage safety, and stable equipment operation. Excessive air humidity can lead to a series of problems, including industrial products becoming damp and damaged, stored goods becoming moldy and deteriorating, and electronic components experiencing short circuits. Therefore, efficient and reliable dehumidification equipment has become an indispensable infrastructure in these fields.

[0003] Rotary dehumidifiers, with their unique adsorption dehumidification principle, possess significant advantages such as high dehumidification efficiency, stable dehumidification capacity, and normal operation in low-temperature and low-humidity environments, and are gradually being widely used in various industries with dehumidification needs. Their core working mechanism revolves around a dehumidification rotor filled with highly efficient adsorption material. During operation, humid air first enters the dehumidification zone, making full contact with the adsorption material on the rotor surface. The moisture in the air is firmly captured by the adsorption material, achieving air drying. Subsequently, the dehumidified rotor rotates to the regeneration zone, where high-temperature regeneration hot air passes through the rotor, heating and desorbing the moisture stored in the adsorption material, restoring the rotor's adsorption capacity. This cycle repeats continuously, ensuring a stable output of dry air.

[0004] In the overall structure of a rotary dehumidifier, the air duct system plays a crucial role. It is the core channel connecting the air intake, dehumidification zone, regeneration zone, and air outlet, directly determining the airflow path, speed distribution, and contact state with the dehumidification rotor inside the equipment, thus having a decisive impact on the dehumidifier's dehumidification efficiency, energy consumption level, and operational stability.

[0005] However, in current practical applications, the duct systems of existing rotary dehumidifiers generally suffer from numerous technical problems that urgently need to be addressed. On the one hand, in the duct design phase, insufficient consideration of airflow dynamics leads to severely uneven airflow distribution within the duct. In some areas of the duct, the airflow velocity is too high, significantly shortening the contact time between the humid air to be treated and the dehumidifying rotor in the dehumidification zone. This prevents the adsorption material from fully capturing moisture from the air, directly resulting in a significant reduction in dehumidification efficiency. On the other hand, in other areas of the duct, the airflow velocity is too slow, causing air stagnation in that area, affecting overall air circulation efficiency, and making it difficult for the overall dehumidification capacity of the dehumidifier to meet design standards and actual dehumidification needs.

[0006] On the other hand, in terms of duct structure design, most existing rotary dehumidifiers adopt an integrated duct design. While this structure simplifies the production and assembly process to some extent, it reveals significant drawbacks in actual use and maintenance. First, the integrated structure makes duct disassembly extremely inconvenient. When cleaning, inspection, or parts replacement is required, workers often need to spend a lot of time and effort disassembling the main body of the equipment, greatly increasing maintenance costs and downtime. Second, the sealing design of the integrated duct has serious defects. Because the entire duct is a single sealed space, if a leak occurs in any part of the duct, such as a cracked weld or loose joint, untreated humid air from the outside can seep into the duct, or treated dry air inside the duct can leak out. This not only further reduces dehumidification efficiency but also significantly increases equipment energy consumption. More seriously, the appearance of a single leak can cause the sealing function of the entire duct system to fail, resulting in the equipment's inability to operate normally. The entire duct must be repaired or replaced, causing huge economic losses and production disruptions for users.

[0007] Therefore, we proposed a rotary dehumidifier duct structure to solve the above problems. Utility Model Content

[0008] (a) Technical problems to be solved

[0009] In view of the shortcomings of the prior art, this utility model provides a rotary dehumidifier air duct structure to solve the problems mentioned in the background art.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution: a rotary dehumidifier duct structure, including a dehumidifier housing, an air inlet pipe fixedly connected to one side wall of the dehumidifier housing, the air inlet pipe penetrating through the dehumidifier housing, a filter plate A fixedly connected inside the air inlet pipe, and a cover plate fixedly connected to the bottom surface of the inner cavity of the dehumidifier housing.

[0012] Preferably, a flow equalization plate is fixedly connected to the inner cavity of the cover plate, and the inner cavity of the cover plate is divided into a dehumidification air duct and a regeneration air duct by the flow equalization plate.

[0013] Preferably, the side wall of the cover plate is fixedly connected to the airflow conduction chamber A, and the connection ports are symmetrically opened at the connection between the cover plate and the airflow conduction chamber A.

[0014] The airflow conduction chamber A is fixedly connected to a dehumidifying rotary chamber on the side away from the cover plate. The dehumidifying rotary chamber has four equally spaced flow channels. There are four equally spaced flow channels. The airflow conduction chamber A has another connection port on its upper part. The connection port of the airflow conduction chamber A is connected to one of the four flow channels.

[0015] Preferably, the side of the dehumidifying rotary chamber away from the airflow conduction chamber A is fixedly connected to the airflow conduction chamber B, and the side of the airflow conduction chamber B away from the dehumidifying rotary chamber is fixedly connected to the air outlet pipe.

[0016] Preferably, a regenerated air input pipe is fixedly connected to the opposite side of the air inlet pipe on the dehumidifier casing, and a filter plate B is fixedly connected inside the filter plate A.

[0017] Preferably, the dehumidifying rotor chamber is equipped with a dehumidifying rotor for adsorbing moisture in the air.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a rotary dehumidifier air duct structure, which has the following beneficial effects:

[0020] 1. The design of the flow equalization plate in this utility model can bring the following benefits to the overall operation:

[0021] Optimize the airflow distribution inside the dehumidifier casing: The flow equalization plate can guide and divert the airflow entering the dehumidifier casing, breaking the problems of turbulent airflow and excessive local velocity differences in the original air duct system; when the airflow passes through the flow equalization plate, it will be evenly distributed to various areas inside the dehumidifier casing, avoiding the situation of airflow gathering in some areas and airflow sparse in some areas, making the airflow inside the entire dehumidifier casing more stable and orderly, fundamentally improving the drawbacks of uneven airflow distribution;

[0022] Extending the contact time between air and the dehumidifier rotor: The airflow equalization plate effectively slows down the airflow speed within the dehumidifier casing by optimizing the airflow path and velocity, avoiding the problem of insufficient contact time caused by excessively fast airflow in the original design. The humid air to be treated can come into full contact with the adsorption material on the surface of the dehumidifier rotor at a more reasonable speed, ensuring that the moisture in the air has enough time to be captured by the adsorption material, reducing moisture residue caused by insufficient contact time, and further improving the effect of a single dehumidification process.

[0023] 2. This utility model, through its detachable connection design of the cover plate, airflow conduction chamber A, dehumidification rotor chamber, and airflow conduction chamber B, brings the following benefits to the overall operation:

[0024] Significantly improves the ease of duct disassembly: Through the modular connection design of the cover plate, airflow conduction chamber A, dehumidification rotor chamber, and airflow conduction chamber B, the limitation of the integrated duct being difficult to disassemble is broken; the components can be separated through simple disassembly operations, without the need for large-scale disassembly of the main structure of the dehumidifier. Staff can quickly disassemble the various parts of the duct without the need for complicated tools or a lot of physical labor, which significantly reduces the difficulty and time cost of duct disassembly operations, making the preparation work before equipment maintenance more efficient;

[0025] Facilitates cleaning and organization of the duct interior: Each disassembled duct component (cover plate, airflow conduction chamber A, dehumidification impeller chamber, airflow conduction chamber B) can be cleaned individually. Workers can directly access every corner of the duct interior, including areas difficult to reach in traditional integrated ducts such as crevices and corners. Whether removing accumulated dust and impurities or addressing any relocation of wiring or pipes, the process is more thorough and convenient, effectively preventing airflow blockages and adsorption material contamination caused by incomplete duct cleaning, thus ensuring a clean duct interior environment.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0035] Example

[0037] A rotary dehumidifier duct structure includes a dehumidifier housing 1, an air inlet pipe 2 fixedly connected to one side wall of the dehumidifier housing 1, the air inlet pipe 2 penetrating the dehumidifier housing 1, a filter plate A3 fixedly connected inside the air inlet pipe 2, a cover plate 4 fixedly connected to the bottom surface of the inner cavity of the dehumidifier housing 1, a flow equalization plate 7 fixedly connected to the inner cavity of the cover plate 4, the cover plate 4 being divided into a dehumidification duct 5 and a regeneration duct 6 by the flow equalization plate 7, an airflow conduction chamber A8 fixedly connected to the side wall of the cover plate 4, and symmetrical connection ports opened at the connection between the cover plate 4 and the airflow conduction chamber A8; a dehumidifier rotor is fixedly connected to the side of the airflow conduction chamber A8 away from the cover plate 4. The dehumidifier rotor chamber 9 has four equally spaced flow channels 10. The flow channels 10 have four equally spaced channels. The airflow conduction chamber A8 has another connection port on its upper part. The connection port of the airflow conduction chamber A8 is connected to one of the four flow channels 10. The side of the dehumidifier rotor chamber 9 away from the airflow conduction chamber A8 is fixedly connected to the airflow conduction chamber B11. The side of the airflow conduction chamber B11 away from the dehumidifier rotor chamber 9 is fixedly connected to the air outlet pipe 12. The opposite side of the air inlet pipe 2 on the dehumidifier casing 1 is fixedly connected to the regenerated air input pipe 13. The filter plate B14 is fixedly connected inside the filter plate A3.

[0038] in:

[0039] Filter plate A3 is used to filter impurities carried in humid air to avoid affecting the drying efficiency of the dehumidifying impeller.

[0040] The airflow equalization plate 7 is used to ensure that the airflow inside the dehumidifier is evenly distributed.

[0041] The dehumidifying rotor chamber 9 is equipped with a dehumidifying rotor for adsorbing moisture in the air.

[0042] The regenerated air inlet pipe 13 is used to connect to the hot air conveying device.

[0043] Working principle:

[0044] During use, humid air enters through the air inlet duct 2, and the filter plate A3 filters out impurities carried in the air. When the humid air enters the cover plate 4, with the assistance of the dehumidification duct 5 and the flow equalization plate 7, the humid air is transferred to the regeneration duct 6 and finally enters the airflow conduction chamber A8 through the connection port. Furthermore, the humid air enters the area where the dehumidification wheel chamber 9 is located. At this time, the dehumidification wheel in the dehumidification wheel chamber 9 will adsorb the moisture in the humid air. The adsorbed dry air will be transferred out through the air outlet duct 12 on the airflow conduction chamber B11.

[0045] Furthermore, when the dehumidifying rotor in the dehumidifying rotor chamber 9 has been used for a long time, high-temperature hot air can be transmitted to the area where the dehumidifying rotor chamber 9 is located through the regeneration air inlet pipe 13, thereby treating the dehumidifying rotor in the dehumidifying rotor chamber 9.
