Small device for extracting water from air based on adsorption and semiconductor refrigerating and method of small device

Abstract

The invention discloses a small device for extracting water from air based on adsorption and semiconductor refrigerating and a method of the small device. The device for extracting water from air comprises an air inlet, an air-inlet fan, electric heating wires, an adsorption bed, an inner shell, an inner shell air outlet, a condensing static-pressure cabin, condensing sheets, a semiconductor refrigerating sheet, heat-insulating cotton, a cooling fan, cooling fins, outer shell air outlets, an outer shell, a reservoir, a water outlet and a base. In an adsorption stage, the air, which is dehumidified by virtue of the adsorption bed, is discharged from the air outlets; and in a desorption water extracting stage, the air, which is heated by virtue of the heating wires, passes through the adsorption bed, and meanwhile the semiconductor refrigerating device begins to work, so that high-humidity air becomes cold and condensed to generate water beads and the water beads flow into the reservoir along the wall surface of the semiconductor refrigerating device. The small device for extracting water from the air provided by the invention has the advantages of being small in volume, simple in structure, compact in parts, capable of extracting water under the circumstance that humidity is quite low and the like.

Description

technical field [0001] The invention relates to the field of air water intake, in particular to a small air water intake device based on adsorption and semiconductor refrigeration and a method thereof. Background technique [0002] As an ancient country with a history and civilization, my country is rich in resources of movable cultural relics. In order to display the cultural relics more clearly and meet the occasional demand for cultural relics to be exhibited in different places, it is often necessary to use small independent cultural relics display cabinets with constant temperature and humidity. Common small display cabinets realize the humidity control inside the display cabinet through the mass transfer in the process of direct contact between air and water in the internal water tank. Among them, water will be absorbed from the water tank during the humidification process. Therefore, in actual operation, it is necessary to manually add water to the water storage tank ...

AI Technical Summary

Problems solved by technology

However, the refrigeration cooling method in the previous air water intake method has a large initial investment and consumes a lot of energy; while the absorption water intake equipment is complex and bulky; although the adsorption method has the advantages of small size and low working humidity requirements, the adsorption water intake system currently studied There are problems such as complex structure, large volume, and long water intake cycle, so it is necessary to re-develop a new type of small air water intake device
