Island air water extracting device and water extracting method thereof

Abstract

The invention discloses an island air water extracting device and a water extracting method thereof. The island air water extracting device comprises a concentrated solution air water extracting system, a solar thermal collector, a diluted solution dehydrating system, a heat pump system, a solution heating system and a water purifying system; island wet air is introduced into the concentrated solution air water extracting system to perform heat and mass exchange to obtain a diluted solution and relatively low-temperature dry air, wherein the air serves as indoor fresh air; the diluted solution is delivered into the solar thermal collector for heating and then is delivered into the diluted solution dehydrating system; after the diluted solution is delivered into the solution heating system and is heated by the diluted solution dehydrating system, the diluted solution evaporates to form water vapour, and the water vapour is delivered into the water purifying system; the water purifying system cools the water vapour, and the water vapour is purified, filtered and stored; meanwhile, the heated island wet air is introduced into the diluted solution dehydrating system by the heat pump system, so that the heat of the wet air is recycled, and the moisture in the wet air is extracted. According to the island air water extracting device and the water extracting method thereof, the air which is produced in a water extracting process is directly taken as the indoor fresh air, so that the air is utilized reasonably.

Description

technical field [0001] The invention relates to air water intake technology, in particular to an island air water intake device and a water intake method thereof. Background technique [0002] At present, the way to obtain fresh water in islands without fresh water is to use desalination of sea water, and to use shipping or air transportation. Once the water source in the offshore waters of the island is polluted and destroyed, the fresh water supply will be cut off. Because the air humidity of the island is high and rich in fresh water, it is a new and important way to meet the needs of human life on the island to study a device for obtaining fresh water from the air of the island. [0003] Relevant research has been carried out on air water intake technology at home and abroad. The main water intake methods are moisture absorption / desorption method and refrigeration condensation method. The primary energy sources of water intake devices include solar energy, wind energy, ...

AI Technical Summary

Problems solved by technology

The air humidity on islands is above 90% and contains a certain amount of salt. The existing air-conditioning technology can achieve the relatively low-temperature and low-humidity air required by the living environment, but the energy consumption is high, and the problem of salt content in the air is currently One of the problems that air-conditioning technology has not effectively solved

[0006] To sum up, none of the above-mentioned methods consider the utilization of dry air after extracting fresh water, energy saving, large-scale equipment, and industrialization.
