Adsorption-condensation type air water taking device

Abstract

The invention provides an adsorption-condensation type air water taking device which is used for continuously taking water. The device comprises a shell, an air filter screen, a separation type adsorption bed, an evaporator, a condenser, a compressor, a water pan, a water storage device, a water filter, a fan and a motor. The separation type adsorbent bed used in the invention combines the hydrogel and a heat exchanger, heat and mass transfer performance of the hydrogel in the adsorption and desorption processes is enhanced, heat and moisture transfer efficiency of air-materials is improved, adsorption-condensation circulation based on a separated adsorption bed is further used, a dew point of air is improved by adopting adsorption circulation, and unit water taking energy consumption in the condensation process is reduced. Besides, the dew point of the air flowing through the adsorption bed can be improved through adsorption-condensation circulation based on the separation type adsorption bed, so energy consumption is reduced, efficiency is improved, and a water taking unit based on the separation type adsorption bed is relatively small, convenient and particularly suitable for flexible water supply in desert arid areas.

Description

technical field [0001] The invention relates to an air water intake device, in particular to an adsorption-condensation air water intake device. Background technique [0002] Water is the source of life, and it is also an indispensable resource for human beings to carry out various activities such as marching, scientific research, and exploration in the desert. Nowadays, water resources are scarce. From the perspective of the entire hydrosphere, the seawater in the surface water accounts for about 97.5% of the entire hydrosphere, while the freshwater resources that can be directly used by humans only account for 0.00768%, which is extremely limited. But what few people notice is that the volumetric storage of atmospheric freshwater accounts for 0.04% of the global volumetric storage of freshwater, which even exceeds the total amount of available freshwater in swamps, wetlands and rivers around the world. [0003] The water vapor in the air has large reserves, is relatively ...

AI Technical Summary

Problems solved by technology

But among them, condensing air water intake is a common way of water intake. However, in the case of low dew point, the efficiency of water intake will be greatly reduced, and even the device cannot operate. It is difficult to obtain water effectively in arid areas with low temperature and dew point temperature usually lower than 10°C, such as the air condensing fresh water intake machine with application number 201420780374.5; the membrane separation method is usually used for seawater desalination, and it is often used in coastal areas, which is subject to geographical restrictions And it needs to consume a lot of electric energy, such as the seawater desalination system and seawater desalination method with the application number of 201280009591.8; although the pure adsorption water intake device is not restricted by region, the device is large in size and difficult to transport, so it is difficult to meet the high mobility of personnel in desert areas. , the location is uncertain, and only intermittent water intake can be realized, such as a continuous circulation air water intake device with application number 202010147945.1
