The air water taking technology is a promising and flexible water supply mode. The adsorption method is to absorb water vapor in wet air with liquid or solid desiccant and to obtain required fresh water through regeneration of the desiccant. Compared with the traditional air water taking technology, the adsorption type air water taking device has the advantages of small size, high water taking efficiency, simple structure, energy conservation, environmental protection and the like.

Concrete curing refers to artificially creating humidity and temperature conditions so that the poured concrete can be normal or accelerated to harden and increase the strength. Proper temperature and humidity are indispensable in the concrete curing process, otherwise, the concrete performance can be greatly influenced. For ordinary portland cement concrete, the curing time must be longer than seven day and night, and the concrete must be kept wet in the process. Today, as the building industry develops rapidly, people need to use large-volume concrete, and the concrete is larger in volume and more difficult to permeate water.

The existing natural curing technology has the problems of complicated curing process, waste of a large amount of water resources, manpower and the like.

Namely: the device adopts a columnar movable shell, is controlled by a shell driving device and is powered by solar energy absorbed in the daytime, so that the device can fully absorb water when being exposed in the air at night, and can be heated and desorbed by solar radiation in the daytime to realize full-automatic adsorption-desorption. In the aspect of condensing equipment, the mode of phase-change material interlayer is adopted, so that high-efficiency cold accumulation can be realized, and a better condensation effect is achieved. For the adsorption bed with the core problem of the adsorption method, silica gel-CaCl with higher economic benefit is filled₂To enhance the core capabilities of the overall device. The device separately works night and daytime, and the water content of collecting will be used for the concrete maintenance of below through aperture throttling arrangement, can guarantee that 24 hours of the whole day concrete all has suitable temperature and humidity, and great liberation the manpower.
