Embodiment Construction

[0018] Using the dual heat source spray evaporation seawater desalination device of solar air heat collector and solar water heater, using the dual heat source of solar air heat collector and solar water heater as energy, the solar air heat collector can increase the air temperature to 80-100 Celsius, the solar air heat collector is connected to the evaporator through an insulated tube, and a fan is connected in the middle to speed up the air circulation. The evaporator has dense copper tubes connected to the solar water heater to circulate hot sea water. There is a concentrated seawater discharge port under the evaporator. The condenser is on one side of the evaporator. Hot water vapor flows in from the evaporator and liquefies into fresh water in contact with the dense cold copper tube. The outlet pipe of the condenser passes through the vapor-liquid The separator flows into the fresh water collection tank; there is also a dry air discharge above the condenser. There is a co...

Abstract

The invention discloses a device adopting a dual-heat-source spray evaporation seawater desalination technology which uses a solar air collector and a solar water heater. The device comprises a water cooling tank, the solar water heater, an evaporator, the solar air collector, a condenser, a concentrated seawater collection box, a gas-liquid separator, a freshwater collection box, a supercharge pump, a spray device, a filter, a temperature sensor and the like. Seawater in the water cooling tank is sprayed into the evaporator after the seawater is heated by the solar water heater, high-temperature air generated by the solar air collector is blown into an evaporation chamber by a blower so as to be mixed with water mist, and water vapor generated by the evaporation of the water mist when the water mist is exposed to heat is led into the condenser; remained water in the evaporator is drained into the concentrated seawater collection box; the water vapor entering the condenser is liquefied when the water vapor is exposed to cold, and the liquefied water vapor flows into the freshwater collection box through the gas-liquid separator; and cooling seawater passes through a condensing chamber, then, enters the water cooling tank, and circularly flows after being cooled. The device for seawater desalination is applicable to households or small factories and has the advantages of energy saving performance and high efficiency and the like.

Description

technical field [0001] The patent of the present invention is a dual heat source spray evaporation seawater desalination technology of a solar air heat collector and a solar water heater, and relates to the technical field of seawater desalination. Background technique [0002] With population growth and rapid economic development, human demand for fresh water continues to increase. Due to water pollution, soil erosion and land desertification caused by environmental damage, many countries and regions in the world are facing a water resource crisis. How to solve the shortage of human water resources is an urgent problem in the world. [0003] China is a country seriously short of water resources. The per capita water resources are only 2,200 cubic meters, which is only 1 / 4 of the world's per capita water resources. It ranks 110th in the world and has been listed by the United Nations as one of the 13 water-poor countries. . In the past 20 years, with the increase of popula...
