Adsorption-based external-heating small air water taking device and method

Abstract

The invention discloses an adsorption-based external-heating small air water taking device. The small air taking device is suitable for small constant temperature and constant humidity air conditioning cabinets in museums to provide protection for cultural relics. The small air water taking device comprises a heating belt, an adsorption bed, a water storage tank, a cooling fan, an adsorption bed outer wall, a base and the like. In the adsorption stage, an air inlet fan works, air enters an annular flow passage between the adsorption bed outer wall and an outer porous cylinder through an air inlet, enters the adsorption bed, passes through an adsorbent and is discharged from a central flow passage; in the desorption water taking stage, after air is heated by the heating belt, the heated airflows through the adsorption bed to heat the adsorbent, and accordingly, water accumulated in the adsorption stage is taken away, the air with high humidity condenses into water droplets when in contact with the cold surface, the cooling fan takes away excess heat, the water droplets flow into the water storage tank along the wall surface after condensation, and the function of water taking is achieved. The device has the advantages of small size, simple structure, compact parts and the like, damageable parts such as valves are avoided, and water can still be taken at the low dew point temperature.

Description

technical field [0001] The invention belongs to the field of air water intake, and in particular relates to an adsorption-based external heat type small air water intake device and a method thereof. Background technique [0002] The temperature and humidity of the environment have a crucial impact on the preservation of cultural relics. As a place for the storage and exhibition of precious cultural relics, museums should maintain the temperature and humidity within the range suitable for the preservation of cultural relics. In response to the special requirements of the museum, the museum not only has a central air-conditioning system that bears the daily heat and humidity load, but also has a constant temperature and humidity air-conditioning system specially used for warehouses and exhibition halls. [0003] The cultural relics in the museum need to be exhibited outside and independently. Therefore, small constant humidity temperature display cabinets are often used in mus...

AI Technical Summary

Problems solved by technology

The previous air water intake method has the following shortcomings and defects: the initial investment and energy consumption of the refrigeration condensation method are large, and it is not suitable for small museum showcases; the fog gathering water intake method requires high environmental humidity; the absorption water intake equipment is bulky

The existing adsorption water intake system has problems such as long water intake cycle, large size, complex structure, and not suitable for low dew point temperature conditions. Therefore, there is currently no automatic air water intake solution that can solve the problem of water replenishment for small museum constant humidity display cabinets.
