[0002] With the rapid development of social economy, the global water shortage problem is becoming increasingly serious, and the water crisis has become the world's second largest environmental problem after global warming. Most of the water resources on the earth are stored in the ocean, and seawater desalination technology has become an important way to solve the problem of water shortage in the world, especially in coastal and island areas. At present, my country's seawater desalination technology has gradually matured, but traditional seawater desalination technology has problems such as over-reliance on fossil energy, high energy consumption, high operating costs, and environmental pollution. In areas with relatively rich wind resources, the use of wind power generation, and then electric heating or driving vapor compression cycle to desalinate seawater has begun to be used, but the investment cost is high, and the refrigerant of the vapor compression refrigeration system has an adverse effect on the environment. Utility Model Content

[0004] The technical solution provided by the utility model is as follows: a seawater desalination device with wind-driven vortex refrigeration, which includes a wind-driven system, characterized in that the wind-driven system is connected to a vortex tube refrigeration system, and the vortex tube refrigeration system is connected to a seawater desalination system; the vortex tube refrigeration system includes an air compressor and a vortex tube; one end of the air compressor is connected to the wind-driven system, and the other end is connected to the inlet of the vortex tube; the seawater desalination system includes a shell-and-tube heat exchanger, a box, and an air duct, and the air inlet of the shell-and-tube heat exchanger is connected to the heat pipe end of the vortex tube The liquid outlet of the shell-and-tube heat exchanger is connected to one end of the first water pump, the other end of the first water pump is connected to the inlet of the heating pipe in the box, and the outlet of the heating pipe is connected to the liquid inlet of the shell-and-tube heat exchanger; a water baffle is arranged on the top of the box, the air outlet of the box is connected to the steam inlet of the air duct, a fan is arranged in the air duct, a sprayer is arranged between the water baffle and the heating pipe in the box, and the first water outlet of the box is connected to the water inlet of the sprayer through the second water pump; the cold air inlet of the air duct is connected to the cold pipe end of the vortex tube, and the condensate valve is connected to the water outlet of the air duct.

[0005] Furthermore, the wind drive system includes a wind turbine, a first gearbox, a second gearbox, a third gearbox, a first clutch connected to an air compressor, a second clutch, and a generator.

The two output ends of the third gearbox are respectively connected to the first clutch and the second clutch, and the other end of the second clutch is connected to the generator.

[0006] The beneficial effects of the utility model are as follows: the utility model drives the blades to rotate through wind power, drives the air compressor through a multi-stage gearbox, uses the heat generated by the vortex tube to heat the seawater to obtain water vapor, and uses the cold energy generated by the vortex tube to condense the water vapor to obtain desalinated water. The utility model can be used in coastal areas and islands and other areas with abundant wind resources and urgent demand for fresh water.

Refrigeration through the vortex tube does not consume electricity, and the vortex tube has a simple and compact structure and low cost, which greatly reduces the cost of seawater desalination; using air as the refrigeration medium achieves the purpose of cleanliness and efficiency.

[0008] Second, the utility model utilizes the heat generated by the vortex tube to heat seawater to obtain water vapor, and utilizes the cold generated by the vortex tube to condense the water vapor to obtain desalinated water, thereby improving the efficiency of seawater desalination, ensuring the quality of fresh water, achieving reasonable distribution and utilization of energy, and improving energy utilization.

[0009] Third, the utility model captures wind energy through blades to drive the shaft to rotate, converting wind energy into mechanical energy, thereby driving the clutch to drive the generator to generate electricity and the air compressor to work, realizing the application of clean energy, meeting the system operation while protecting the environment, and achieving the effect of energy conservation and emission reduction.

[0010] Fourth, the electricity for water pumps, fans and other equipment in the desalination device is provided by wind-driven generators, ensuring the normal operation of the distributed power supply and desalination system.

[0011] Fifth, a shell-and-tube heat exchanger, a first water pump, and a heating tube are used to form a hot water circulation, which continuously absorbs the heat released by the vortex tube and is used to heat the seawater. A second water pump, a sprinkler, a water baffle and other equipment are used to achieve efficient desalination of seawater. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] When driven by wind, the wind energy is captured by the blades 19 and drives the shaft to rotate, thereby converting the wind energy into mechanical energy.
