Device capable of obtaining water from air

Abstract

The invention discloses a device capable of obtaining water from the air. The device comprises a solar air heat collector, a solar photovoltaic power generation unit, a compression refrigeration unit and a reel dehumidification unit, wherein the solar air heat collector is used as a heat resource for the reel dehumidification unit; the solar photovoltaic power generation unit provides a required power supply to the reel dehumidification unit and the compression refrigeration unit; the compression refrigeration unit is used for compressing and refrigerating; and the reel dehumidification unit is used for eliminating moisture. The device capable of obtaining water from the air utilizes the solar energy as the energy for obtaining water from the air, so that fossil fuel does not need to be carried in the process of obtaining the water from the air, and the energy consumption for obtaining the water from the air is reduced. Meanwhile, compared with a refrigeration and moisture condensation method, the device can normally obtain water when the air humidity is relatively low, water can be continuously fetched, and the water fetching efficiency is improved.

Description

Technical field [0001] The invention relates to the field of air water extraction, and in particular to a device for continuously extracting water from the air by a solar energy photothermal photovoltaic driving dehumidification rotor. Background technique [0002] Due to the warming of the climate, the depletion of many rivers and lakes, the decline of groundwater levels, coupled with environmental pollution and irrational use of people, terrestrial freshwater resources have been facing a serious crisis. In some areas with aridity and low rainfall, such as deserts and Gobi, the lack of fresh water is especially true. People living here or doing activities here need fresh water supplies. In addition to liquid water, water also exists in the air in a gaseous state. Therefore, water extraction from air has become a hot issue in current research. [0003] As a renewable and clean energy, solar energy has attracted more and more attention. Drought and rainless and mountainous areas l...

Problems solved by technology

However, the circulation loop in this system is not optimized, and the use of electric heaters to provide heat for the regeneration of the runners requires more energy consumption, and the power also needs to be provided externally.

The Chinese patent application number is 200820025836.7. On the basis of the Chinese patent application number 200820025835.2, the air water intake device and diesel generator are combined to form a shelter, which realizes the self-sufficiency of electric power, but still needs to carry fuel, and the energy The efficiency is not high, which is not conducive to the production of fresh water in large quantities

[0007] From the above searches, it can be seen that the existing technology has problems such as inability to continuously fetch water, low efficiency or need to carry a large amount of fuel, low thermal energy utilization rate, uneconomical and need for a generator, complex system, poor reliability, etc.
