Air water taking device based on chimney effect

Abstract

The invention relates to an air water taking device based on a chimney effect. The air water taking device comprises a water taking box body, wherein a secondary water collecting device is arranged at the top of the water taking box body, and a water collecting box is arranged at the bottom of the water taking box body; the secondary water collecting device is fixed at the top of the water taking box body through brackets which are distributed at equal intervals in the circumferential direction; the water taking box body is fixed on the water collecting box through a plurality of upright posts; the water taking box body comprises a shell; a heat insulating layer is arranged in the shell; the heat insulating layer and the shell are coaxially arranged; a plurality of uniformly distributed ventilation pipelines are arranged in the heat insulating layer; the ventilation pipelines are cylindrical; a primary water collecting device is arranged on the inner surface of each ventilation pipeline; the outer surface of each ventilation pipeline is coated with a phase change material; and the top and the bottom of each ventilation pipeline communicate with the atmosphere respectively. According to the air water taking device, the characteristics of heat absorption and heat release of the phase change energy storage material under the influence of day and night temperature difference are utilized, the chimney effect is combined to directionally drain air with higher humidity, and a special water collecting sail is utilized to effectively extract moisture in the air.

Description

technical field [0001] The invention belongs to the technical field of air water intake, and in particular relates to an air water intake device based on the chimney effect. Background technique [0002] It is estimated that even in desert areas, the water content exceeds 10g / m 3 . There are sometimes valuable mineral deposits in the desert, and many oil deposits have been discovered in modern times. There are few inhabitants in the desert, and resource development is also relatively difficult. In order to develop desert resources, a livable environment is required. The desert climate is dry, the annual rainfall is very scarce, but there is a lot of water vapor in the air. Especially in the early morning, due to the temperature difference between day and night, the water vapor content in the air reaches its peak. How to get water from the air without being affected by wind and sand is an important issue in building a suitable human living environment. [0003] The main i...

Problems solved by technology

This solution is low in cost and widely used, but the structure is relatively simple, but it is greatly affected by the weather, and the temperature difference in desert areas is large, affecting humidity, and there will be strong convection and large wind and sand

The water and sand collected by this scheme are more, and it is easy to evaporate, so the efficiency is low
