Internally-heated small air water taking device and method based on adsorption

Abstract

The invention discloses an internally-heated small air water taking device and method based on adsorption. The small air water taking device comprises an adsorption working condition and a desorptionworking condition. Under the adsorption working condition, an air inlet fan works, the air enters a center runner in an inner porous cylinder through an air inlet and radially enters an adsorption bed, moisture absorption of the air is implemented by adsorbent, and the air passes an annular runner and a steady-flow hydrostatic cavity and then discharged. Under the desorption working condition, theair enters the center runner from the air inlet, is heated by a heating bar arranged in the center runner and flows the adsorption bed to heat the adsorbent to take away and adsorbs aggregated moisture, high-humidity air condenses water drops through circular fins, excess heat is taken away by a cooling fan, condensed water drops flow into a water storage tank along a wall surface, and water is taken by the air. The same runner is shared under the adsorption working condition and the desorption working condition, and the air centrifugally and radially flows. The device has the advantages thatthe device is small in size and simple in structure, water can still be taken at low-dew-point temperature, energy is saved and the like.

Description

technical field [0001] The invention belongs to the field of air water intake, in particular to an adsorption-based internal heat type small air water intake device and method. Background technique [0002] As a cultural place for the collection and exhibition of precious cultural relics such as calligraphy and painting, museums often need to be equipped with small constant humidity cultural relics display cabinets for the protection of cultural relics and the needs of off-site exhibitions. This kind of small constant humidity cultural relic display cabinet adopts direct contact constant humidity equipment, and realizes high-precision control of the air humidity in the display cabinet by adjusting the mass transfer process of the air in the internal water tank in contact with water. Among them, the humidification process consumes water continuously, and it is necessary to continuously replenish water to the water storage tank of the constant humidity equipment. Small cultur...

AI Technical Summary

Problems solved by technology

The existing adsorption water intake system has problems such as long water intake cycle and large volume that cannot be applied to small constant temperature and humidity display cabinets. Therefore, the research and development of a compact structure, short water intake cycle, and convenient water intake device has a high impact on the protection of cultural relics. Practical value and practical significance
