Embodiment Construction
[0014] The principle, structure and specific methods of the present invention will be further described below in conjunction with the accompanying drawings.
[0015] figure 1 It is a structural schematic diagram of a solar energy-heat pump-indirect absorption seawater desalination device. The device mainly includes a photovoltaic panel 1, a water pump 13, a condensation heat exchanger (a) 6, a heat exchanger (b) 17, seawater evaporation equipment 12, a desalination water tank 8, and a heat pump system; the heat pump system includes an expansion valve 2 , condenser 3, compressor 4 and evaporator 5.
[0016] The solar light energy irradiated on the photovoltaic panel is converted into two parts of energy, one part is based on the photovoltaic effect, and the solar radiant energy is directly converted into electrical energy output through the photovoltaic panel; the rest is the heat generated by the solar radiant energy, the heat generated Part of it is absorbed by the photovol...

The invention provides a solar-heat pump sea water desalination device. The device is mainly composed of a photovoltaic cell panel, a heat pump system, sea water evaporation equipment, a heat exchanger, a desalination tank, a water pump, a fan and a pipeline system, wherein the heat pump system comprises a condenser, an evaporator, a compressor and an expansion valve. According to the device disclosed by the invention, fresh water is produced by solar-heat pump coupling, driving force is provided by photovoltaic power generation, and the sea water temperature is directly or indirectly improved by solar energy and the heat pump system, so that the dew point temperature of the air evaporated from the sea water is improved, the heated sea water enters the sea water evaporation equipment and performs heat and moisture transfer with the air, unsaturated air is changed into high-temperature saturated moist air due to sea water evaporation, the high-temperature saturated moist air is subjected to primary condensation in a condensation heat exchanger (a) by environment sea water and then subjected to secondary condensation in the evaporator, and then the condensed fresh water flows into a fresh-water tank through a condenser pipe.
Description
technical field [0001] The invention relates to a seawater desalination device coupled with solar energy and a heat pump, which is suitable for areas where fresh water is scarce and sea water is abundant. Background technique [0002] Currently, about 1 / 3 of the world's population lives in water-scarce countries and regions. By 2025, this number will increase to 2 / 3. Therefore, solving the problem of fresh water supply will become the primary issue of governments. Some scholars have pointed out: fighting for oil now will fight for water in the future. [0003] One of the most important ways to solve the problem of shortage of fresh water resources is to desalinize sea water, because 70% of the earth's surface is covered by sea water, which is rich in sea water resources. However, the traditional seawater desalination technology consumes a lot of conventional energy, aggravates the consumption of resources and brings environmental pollution. Solar energy is a kind of rene...
