[0003] The above-mentioned systems have the following problems: 1) High cost: core electronic components and compressors are expensive; 2) Poor humidity uniformity: Traditional single-point humidification / dehumidification methods tend to create humidity gradients within the chamber, resulting in significant differences in humidity at different locations. This makes it difficult to meet the requirements of application scenarios with extremely high humidity uniformity. Therefore, we proposed a fiber hygroscopic humidity uniformity control chamber.

Detailed Implementation

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-4 A fiber moisture absorption humidity uniform control box is provided. This fiber moisture absorption humidity uniform control box includes a box body 1 and a box door 2. Both the box body 1 and the box door 2 are made of double-layer heat insulation board (inner layer stainless steel, outer layer engineering plastic). It also includes at least one fiber humidity adjustment module, which is filled with highly absorbent fiber material 5. In application, the humidity is passively adjusted by the highly absorbent fiber material 5, without the need for electronic sensors and compressors, which can significantly reduce costs. The air duct 6 is installed on the inner wall of the housing 1 and has a lower inlet 601 and an upper outlet 602. The air duct 6 is connected to the housing 1 through the lower inlet 601 and the upper outlet 602. Humidity turbulence structure; The humidity turbulence structure is located inside the airflow duct 6. The humidity turbulence structure includes a turbine 702 located inside the airflow duct 6. The turbine 702 is driven by a variable frequency motor 701, which is mounted on the airflow duct 6 via a fixing plate. The variable frequency motor 701 has a power of 15W and an adjustable speed of 500-3000rpm. In application, the lower inlet 601 and the upper outlet 602 form an air circulation path. Combined with the humidity turbulence structure (turbine 702), the airflow is forced to mix, solving the problem of humidity stratification inside the chamber and improving uniformity. At the same time, the variable frequency motor 701 can adjust the speed of the turbine 702 to adapt to different humidity control needs, making it energy-saving and flexible.

[0022] Reference Figure 2 and Figure 3The fiber humidity control module is a detachable fiber unit box 4. The fiber unit box 4 adopts an ABS plastic frame. At least one wall of the fiber unit box 4 is a microporous breathable plate 401 (e.g., pore size 0.1mm, air permeability ≥80%). There are multiple fiber unit boxes 4, which are symmetrically arranged on the inner wall of the box 1. In application, the layout of the detachable fiber unit boxes 4 makes it easy to replace or pre-treat fiber materials and is easy to maintain. The microporous breathable plate 401 can ensure efficient moisture exchange. At the same time, the symmetrical distribution of multiple unit boxes can enhance the coverage uniformity of humidity control in the box and avoid local humidity deviation.

[0023] Reference Figure 2 and Figure 3 The highly absorbent fiber material 5 is one or more of cotton, linen, wool, or synthetic moisture-regulating fibers. The highly absorbent fiber material 5 is pretreated with salt solutions of different concentrations or in humid environments to set its equilibrium humidity point. For example, cotton and linen blended fibers (moisture absorption rate ≥12%) or wool pretreated with salt solutions (e.g., treated with 25% magnesium chloride solution, equilibrium humidity 55%RH). In application, the natural / synthetic fiber blend and the complementary moisture absorption of materials such as cotton and linen can adapt to different environmental requirements. At the same time, by setting the equilibrium humidity point of the fiber through pretreatment, precise humidity control can be achieved (e.g., constant humidity preservation of cultural relics), reducing the energy consumption of dynamic adjustment.

[0024] Reference Figure 2 and Figure 4 The inner wall of the air duct 6 is provided with concave and convex guide patterns (not shown in the figure) to guide airflow and reduce resistance. The concave and convex guide patterns are 1mm deep and 5mm apart. In application, the concave and convex guide pattern layout can reduce airflow resistance, improve circulation efficiency and reduce energy consumption.

[0025] Reference Figure 2 and Figure 4 The blades of the Turbine 702 are made of moisture-absorbing and expanding material (moisture-absorbing and expanding wood pulp material), or the blade surface is covered with a moisture-absorbing fiber layer (such as viscose fiber layer, basis weight 80g / m²). In application, the blades designed with moisture-absorbing and expanding material / fiber layer participate in the moisture absorption and release process, enhance the local humidity regulation capability, and can further improve uniformity.

[0026] Reference Figures 1-4 The box 1 has at least one perforated shelf 8 (aluminum alloy perforated plate, hole diameter 2mm, opening rate 60%) inside. The air duct 6 runs through and is fixed on the perforated shelf 8. In application, the perforated shelf 8 design can take into account both load-bearing and airflow, and avoids blocking the air duct.

[0027] Reference Figures 1-4A sealing strip 3 (such as a silicone sealing strip) is provided at the joint between the box body 1 and the box door 2, which together form a sealed humidity control space. A transparent observation window 201 (such as a tempered glass window) is installed on the box door 2 for observing the situation inside the box body 1. The transparent observation window 201 can be fitted with a thermometer and hygrometer scale film for easy visual monitoring. In application, the sealing strip 3 and the transparent observation window 201 work together to maintain airtightness and prevent moisture leakage, while facilitating real-time monitoring of the state inside the box body 1.

[0028] The working principle of this utility model is as follows: Fiber material pretreatment stage: Select the pretreatment scheme according to the target humidity: Low humidity environment (30%RH): Soak the fiber in saturated lithium chloride solution for 24 hours, dry it and pack it into the unit box; High humidity environment (70%RH): Treat the fibers with potassium dihydrogen phosphate solution and use after equilibration; Equipment assembly stage: First, install the pre-treated fiber unit box 4 symmetrically on the side wall of the box 1, then install the hollow shelf 8, ensuring that the air duct 6 vertically passes through the center of the hollow shelf 8, and finally close the box door 2 and check the compression state of the sealing strip 3 (compression amount ≥3mm). Operation and control phase: First, place the items to be stored on the perforated shelf 8, avoiding obstruction of the lower inlet 601 and upper outlet 602 of the airflow duct 6. Then, turn on the variable frequency motor 701 with an initial speed of 1500 rpm. At this time, the turbine 702 drives the airflow, and the air enters from the lower inlet 601. After being absorbed / released by the fiber unit box 4, the moisture is evenly mixed and sprayed out from the upper outlet 602, forming a circulation. During this period, if the humidity uniformity is insufficient (e.g., the difference between the upper and lower layers is >5%RH), the speed of the turbine 702 is increased to 2500 rpm by the variable frequency motor 701 to enhance the turbulence. After long-term operation, the humidity stability is monitored through the observation window 201. Maintenance phase: Remove fiber unit box 4 monthly and expose it to sunlight for 4 hours to restore its moisture absorption. Clean the dust accumulation on the inner wall of the air duct 6 every six months and check the wear of the fiber layer on the turbine 702 blades.

[0029] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
