Description

[Technical field]

[0001] The present invention relates to the field of gas dehumidification, and in particular to a dehumidifying rotor core. [Background technology]

[0002] Rotor dehumidifier is a device that directly removes moisture by physical adsorption. Air or gas passes through the rotor core of the rotor dehumidifier, and the water vapor in it is adsorbed while the air or gas passes through, achieving the purpose of dehumidification, and the rotor core is regenerated by blowing hot air, achieving the purpose of reuse. Rotor dehumidifiers are widely used in the fields of pharmaceuticals, food processing, electronics industry, medical products, defense application industry, etc.

[0003] Currently used rotor cores are generally manufactured using a full coating and impregnation process, which causes the hygroscopic material to be unevenly distributed on the rotor core, making it difficult to control the amount of hygroscopic material carried on the rotor core. In addition, in the process of using hot air to regenerate the core, the rotor core is gradually cooled when the hot air passes through it, which results in an uneven regeneration of the rotor core. This not only results in a low energy utilization rate, but also leads to a significant reduction in the regeneration hygroscopic performance of the rotor core.

[0004] Therefore, how to design a rotor core that can easily control the amount of support and can maintain good regeneration moisture absorption performance has become an issue that must be resolved as soon as possible by those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art by providing a dehumidifying rotor core that has a simple structure, low production costs, can effectively control the loading amount, has a high utilization rate of hot air in the regeneration process, and ensures regeneration moisture absorption performance. [Means for solving the problem]

[0006] The technical solution to achieve the object of the present invention is as follows: a dehumidifying rotor core including a corrugated fiber mat layer and a plate-shaped fiber mat layer, the corrugated fiber mat layer is divided in sequence along the width direction, different divided areas are coated with hygroscopic materials with different dehydration temperatures, and the dehydration temperature gradually increases or decreases, the plate-shaped fiber mat layer is divided in sequence along the width direction, different divided areas are coated with hygroscopic materials with different dehydration temperatures, and the dehydration temperature gradually increases or decreases, the corrugated fiber mat layer and the plate-shaped fiber mat layer are bonded together, so that the change trends of the dehydration temperatures of the hygroscopic materials on the two fiber mat layers are consistent, and the bonded two fiber mat layers are wound along the length direction to form a porous honeycomb-like columnar structure.

[0007] The corrugated fiber mat layer is obtained by press molding a plate-shaped fiber mat with a corrugating machine, and the plate-shaped fiber mat layer has a specification of 50 g / m 2 A glass fiber mat or a ceramic fiber mat is used, which is as follows:

[0008] The specification of the plate-shaped fiber mat layer is 30 g / m 2 The following is the result.

[0009] The width of each divided area of ​​the corrugated fiber mat layer and the board-shaped fiber mat layer is the same.

[0010] The two laminated fiber mat layers are then rolled lengthwise into a porous honeycomb-like cylindrical structure. Effect of the Invention

[0011] When using the above technical solutions, the following beneficial effects are achieved: The dehumidifying rotor core includes a corrugated fiber mat layer and a plate-shaped fiber mat layer. The corrugated fiber mat layer is divided in sequence along the width direction, and different divided areas are coated with hygroscopic materials having different dehydration temperatures, and the dehydration temperatures are gradually increased or decreased, that is, the hygroscopic material coated on the corrugated fiber mat layer has a dehydration temperature that is gradually increased or decreased along the width direction. The plate-shaped fiber mat layer is divided in sequence along the width direction, and different divided areas are coated with hygroscopic materials having different dehydration temperatures, and the dehydration temperatures are gradually increased or decreased, that is, the hygroscopic material coated on the plate-shaped fiber mat layer has a dehydration temperature that is gradually increased or decreased along the width direction. The corrugated fiber mat layer and the plate-shaped fiber mat layer are laminated together, so that the change trends of the dehydration temperatures of the hygroscopic materials on the two fiber mat layers are consistent, and the laminated two fiber mat layers are wound along the length direction to form a porous honeycomb-like columnar structure. The two laminated fiber mat layers are used as the winding material, and the moisture absorbing material with different dehydration temperature is combined with the fiber mat layers, so that when the moist gas or air passes along the axial direction of the rotor core, the water vapor in the gas or air is absorbed by the moisture absorbing material on the wound multi-layer fiber mat layers, thereby achieving the purpose of drying the gas or air and satisfying the moisture absorption needs. When dehydration is required for the regeneration of the dehumidifying rotor core, the hot air is passed through the rotor core along the axial direction, and the inlet end is the area coated with the high dehydration temperature moisture absorbing material, and the outlet end is the area coated with the low dehydration temperature moisture absorbing material, so that the moisture adsorbed by the high dehydration temperature moisture absorbing material is first removed from the high temperature gas, and the high temperature gas is cooled, and then the moisture adsorbed by the low dehydration temperature moisture absorbing material is removed, thereby realizing the step-by-step utilization of energy and efficient gas humidity control.

[0012] The applicant has conducted tests and found that the dehumidifying rotor core manufactured according to the present invention significantly reduces the regeneration air temperature and improves energy utilization efficiency.

The laminated two fiber mat layers are wound along the length direction to form a porous honeycomb-like cylindrical structure. The core blank obtained by winding was first dried at 30°C for 48 hours and then dried at 120°C for 10 hours to obtain a dehumidified rotor core.

The plate-shaped fiber mat layer 2 is divided in the width direction (A and B, A:B=2:1), and different divided areas are coated with hygroscopic materials with different dehydration temperatures, whereby area A is coated with molecular sieve 3A (corresponding slurry composition is molecular sieve 3A 50%, silica sol 20%, and the rest is water), and area B is coated with polyvinyl alcohol with a molecular weight of about 30,000 (corresponding slurry composition is polyvinyl alcohol 10%, silica sol 10%, and the rest is water), and area A has a higher dehydration temperature than area B.

The laminated two fiber mat layers are wound along the length to form a porous honeycomb-like cylindrical structure. The core blank obtained by winding was first dried at 60°C for 24 hours and then dried at 100°C for 24 hours to obtain a dehumidified rotor core.

[0019] Example 3 Referring to Fig. 1, the dehumidifying rotor core includes a corrugated fiber mat layer 1 and a plate-shaped fiber mat layer 2.

The wound core blank is first dried at 40°C for 24 hours, and then dried at 100°C for 24 hours to obtain a dehumidifying rotor core.

[0020] Comparative Example 1 The dehumidifying rotor core includes a corrugated fiber mat layer and a plate-shaped fiber mat layer. Both the corrugated fiber mat layer and the plate-shaped fiber mat layer are coated with only molecular sieve 13X, and then the corrugated fiber mat layer and the plate-shaped fiber mat layer are laminated together. The laminated two fiber mat layers are wound along the length to form a porous honeycomb-like cylindrical structure. The wound core blank is first dried at 40°C for 24 hours and then dried at 100°C for 24 hours to obtain a dehumidifying rotor core.

[0021] A performance comparison was made between the dehumidifying rotor cores manufactured in Examples 1, 2, and 3 and the dehumidifying rotor core manufactured in Comparative Example 1, and the results were obtained in the table below. [Table 1]

[0022] Here, by adjusting the regeneration air temperature, the amount of water captured by the dehumidifier was made similar (represented by "1"), and the energy saving effect was compared by the regeneration air temperature.

[0023] As can be seen from the results in the above table, in the embodiment of the present invention, the regeneration air temperature is significantly reduced, and the energy utilization efficiency is improved.
