Problems solved by technology
The air dehumidification process needs to go through the process of moisture absorption, heat exchange, and heating regeneration. The system is relatively complicated and the equipment is bulky. The hygroscopic agent is in direct contact with the air. Therefore, the quality of the hygroscopic agent solution is greatly affected by the air quality and needs to be replaced regularly.
Although its dehumidification energy consumption is low, it has not been accepted by the market due to factors such as bulky size, high cost, and complicated operation.

Embodiment Construction
[0037] The present invention can be used as an independent dehumidifier, figure 1 It is a structural schematic diagram of the air dehumidification device of the present invention; the air dehumidification device 1 is a connecting pipe with passage openings at both ends, and one end surface of the connecting pipe forms a water vapor collection box 2 with a closed cavity. A plurality of hollow tubes 3 surrounded by solid medium are arranged in the middle of the collecting box 2 . The two channel openings of the communication pipe are respectively an air inlet 4 and an air outlet 5 . A water vapor discharge pipe 6 is arranged on one wall of the collection box 2 outside the communication pipe, and a section of the water vapor discharge pipe 6 is inserted into the cavity of the collection box 2, and the other end is connected with the evacuation device 7 .
[0038] The solid medium that forms the hollow tube 3 has two parts: one part is a skeleton layer, which is a porous resin th...

The invention discloses an air dehumidification method and an air dehumidification device by using the medium pervaporation technology. A solid medium with the characteristics of hydrophilcity and permeability is used as the medium, and the concentration of water vapor in the air on one side of the solid medium is reduced in an evacuation mode, so that difference is formed between the water vapor concentration and the water vapor partial pressure on two sides of the solid medium. Due to the characteristics of the hydrophilcity and permeability of the solid medium per se, the water vapor is separated out from one side with higher concentration to the other side with lower concentration through the solid medium and is removed, so that the water vapor concentration on the side with the higher concentration is reduced so as to achieve the dehumidification effect. The air dehumidification device can be used as a dehumidification device independently. Due to the combination with mature air-conditioning technique, the air dehumidification device can be used as an air-conditioning device or a fresh air fan, and can be combined with a fresh air ventilator. The air dehumidification method and an air dehumidification device can be widely applied to catering, hospitals, schools, shopping centers, hotels, and other public places.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning dehumidification, and in particular relates to the use of a solid medium to effectively separate dehumidified air from other air, change the water vapor concentration in the air on both sides of the medium, and make the water vapor pressure of the air on both sides of the solid medium different. , Water vapor precipitates to the side with low concentration and partial pressure to achieve the purpose of air dehumidification; this dehumidification method is combined with the surface cooler commonly used in air conditioning systems to form fresh air conditioners and mixed air conditioners. Background technique [0002] The current global energy crisis and environmental degradation force people to attach great importance to energy conservation and emission reduction. The field of air dehumidification and even the entire air-conditioning industry are taking active actions, adopting various new ...
