Island water-making device based on air energy and solar energy and method thereof

Abstract

The invention discloses an island water-making device based on air energy and solar energy and a method thereof. The device comprises an air-energy heat pump assembly, a solar-energy heat-collection panel, a four-way valve and a grid seal-plate assembly. The air-energy heat pump assembly and the solar-energy heat-collection panel are used for stepped heating of circulating air in the device. The air-energy heat pump assembly contains an evaporator, a condenser and a compressor. The condenser and the solar-energy heat-collection panel are connected. The solar-energy heat-collection panel and the four-way valve are connected. The four-way valve is connected to a small-scale air pump which is connected to the condenser. The grid seal-plate assembly comprises a grid seal-plate A and a grid seal-plate B which are respectively connected to the four-way valve. An ammonium thiocyanate solution is contained in the grid seal-plate A. Ammonium thiocyanate crystals are put in the grid seal-plate B. A thermal-dissipation copper pipe is connected between the grid seal-plate A and the grid seal-plate B. According to the invention, solar energy and air energy are used as energy sources, and air is cooled and moisture in the air is condensed and separated out to make fresh water. Thus, distributed all-weather water production is realized.

Description

technical field [0001] The invention belongs to the technical field of fresh water preparation, and more specifically, relates to a sea-island water production device and method based on air energy and solar energy. Background technique [0002] Due to the special geographical location of the island area, there is a problem of scarcity of fresh water resources. With the increase in the number of residents in the island area and the development of tourism, the problem of fresh water supply on the island has become increasingly prominent. The island area lacks small and medium-sized, low-cost fresh water. Preparation method. At present, the main water supply method for islands is desalination of seawater, which has the advantages of short construction period and great flexibility in construction scale. [0003] In the prior art, there are mainly the following schemes for water production by seawater desalination: CN201220085939.9 discloses a small-scale diesel seawater desali...

Problems solved by technology

[0003] In the prior art, there are mainly the following schemes for water production by seawater desalination: CN201220085939.9 discloses a small-scale diesel seawater desalination device, which uses a diesel engine as power and uses reverse osmosis to prepare fresh water. The initial basic setting of the device is The investment is large, and at the same time, due to the use of fossil fuels as power, the operating cost is high; CN200510088081.6 discloses a fresh water preparation device for sea islands and ships, which directly uses wind energy on the sea or islands, compresses air and condenses Water is used to produce fresh water, the energy is clean and the cost is low, but the device is still restricted by the instability of wind energy; CN201510120361.4 discloses a dish-type solar seawater desalination device, which uses solar light and heat resources to carry out negative pressure distillation of seawater , and then condense to obtain pure water. This device does not need to consume fossil energy, but its water production is limited by climatic conditions
