Natural heat exchange type air-source fresh water generation method, natural heat exchange type air-source fresh water generation device and fresh water generation system

Abstract

The invention discloses a natural heat exchange type air-source fresh water generation device. The device at least comprises a water diversion mechanism (1), a water condensation mechanism (2) and a power supply mechanism, wherein the water diversion mechanism (1) is used for delivering low-temperature seawater into a seawater pipeline in the water condensation mechanism (2), and the water condensation mechanism (2) comprises an air inducing device (13) and a water condenser (14). The air inducing device (13) is used for inducing damp and hot air into an air duct of the water condenser (14), and the water condenser (14) serving as a water condensation medium enables the induced damp and hot air to be cooled by the seawater so as to generate condensate water. The power supply mechanism is used for supplying power to the whole device. The invention further discloses a fresh water generation system comprising the natural heat exchange type air-source fresh water generation device. The fresh water generation system comprises a breakwater, a header pipe, a water collection and delivery pipe, a fresh water treatment and production operation platform, an outer delivery pipeline and a single-point mooring device. The natural heat exchange type air-source fresh water generation device and the fresh water generation system have the advantages that the condensate water is generated according to a temperature difference of different substances in the nature world, and accordingly energy saving and large-scale fresh water generation are achieved; the whole device can be arranged on the sea, so that land is saved.

Description

technical field [0001] The invention relates to the field of condensed water equipment, in particular to a natural heat exchange air water production method, device and system. Background technique [0002] Freshwater resources in human society are increasingly scarce, and how to obtain large amounts of freshwater efficiently is particularly important. Fresh water on land basically comes from rainfall brought by water vapor evaporated from the ocean. About 71% of the world's area is ocean, and the global annual seawater evaporation is about 360,000 cubic kilometers, of which more than 83%, about 300,000 cubic kilometers, forms oceanic rainfall and returns to the ocean. The annual precipitation in the global oceans is about three times the world's available freshwater reserves of 104,600 cubic kilometers. Based on the per capita freshwater consumption of 2,000 cubic meters per year for the world's 7 billion people, the global average annual water consumption is 14,000 cubic...
