Problems solved by technology

Some require a lot of equipment, and the two-cycle evaporation makes the device too complicated
In addition, the low temperature of solar collectors is also a major reason why the total thermal efficiency and evaporation efficiency of solar seawater desalination devices are low, making it difficult to commercialize

Abstract

The invention relates to a spray evaporating air-moistening de-humidity type solar sea water desalinating device, which belongs to the technical field of solar sea water desalination. The device comprises a solar air collector, a solar vapor collector, a spray evaporator, an air filter, a condensing regenerator and a condensing heat exchanger, wherein the output end of the solar air collector and a sea water input source are respectively connected with a nozzle of the spray evaporator; the solar vapor collector is connected with a radiating pipe of the spray evaporator; the output end of the spray evaporator is connected with the air filter, the condensing regenerator and the condensing heat exchanger in series in sequence; the air output end of the condensing regenerator is connected with the solar air collector; and the output end of the condensing heat exchanger outputs fresh water. The device adopts the processes of air moisture absorption and de-humidity for desalinating sea water, and can be in well operation at a normal pressure, and a vacuum pump is omitted. In addition, the sea water is atomized and heated by an air-sea water mixed spray technique, and the evaporation efficiency is enhanced.

Description

technical field [0001] The invention relates to a device in the technical field of solar seawater desalination, in particular to a small-sized spray evaporation air humidification and dehumidification solar seawater desalination device operating at high temperature and normal pressure. Background technique [0002] With the continuous development of human civilization and continuous progress of society, the shortage of water resources has become a major problem facing mankind in the 21st century. The situation of water resources in my country is even more unoptimistic. As one of the 13 water-scarce countries in the world, the per capita annual water resources are only equivalent to 1 / 4 of the world's average level, and water-scarce cities account for 2 / 3 of the national cities. Sea water resources on the earth are very rich, 97% of the water is in the ocean, which contains a lot of fresh water. The development of seawater desalination is an important strategic approach to s...
