Description
Technical Field
The invention belongs to the technical field of seawater desalination, and particularly relates to a solar heat driven jet sputtering multi-effect composite seawater desalination system.
Background
As is well known, the liquid is heated to generate vapor-liquid separation, and the sewage gas-liquid separation can obtain high-quality good water. This process is commonly referred to as "distillation purification". The utilization of vacuum tube solar energy as a heat source for seawater desalination is recognized as one of the most energy-saving ways. There are two common modes of solar heating of liquids: one is direct heating and one is indirect heating. A common household vacuum tube solar water heater belongs to a direct heating mode.
A solar module for directly heating seawater to evaporate is characterized in that a vacuum tube is directly filled with seawater, and the seawater directly absorbs heat through the inner wall of the vacuum tube. According to the heat power lifting principle, the heat power in the vacuum pipe is transmitted upwards, the seawater in the evaporation tank is subjected to surface evaporation, the heat of the vaporized water is absorbed by the low-temperature raw seawater on the upper layer of the evaporation tank, and the vaporized water flows out after being condensed, so that fresh water can be obtained. The method has simple structure, and fresh water can be obtained without external power. The biggest defects are as follows: because the surface temperature difference is too large, the seawater is easy to scale on the inner wall of the vacuum tube, and the thermal efficiency is rapidly reduced. In addition, the vacuum tube is structurally provided with a single-end opening, so that descaling is extremely difficult or even impossible. A large amount of manpower and material resources are required to be consumed.
A solar heat collector module with indirect heat exchange is characterized in that a U-shaped tube heat exchanger is arranged in a solar vacuum tube; the liquid in the U-shaped pipe can be heated by solar energy. The seawater in the tower can absorb heat and evaporate through power circulation and the heat exchanger in the evaporation tower, and the fresh water is obtained after the heat is released through the condensing tank. The concentration of seawater in the tower is higher and higher, and the seawater is discharged after gradually releasing heat to the original seawater. Obviously, the method needs a power circulating pump, and the pump forcibly drives the medium in the U-shaped pipe to flow, so as to realize the heat exchange between the solar heat collector and the heat exchanger of the evaporation tower. It has obvious disadvantages: firstly, the forced power circulation needs to consume larger electric energy; secondly, the circulating pipeline with large length has large heat loss and low system heat efficiency; thirdly, high temperature resistant circulating medium is needed, and the investment of system equipment is large and the cost is high.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-11, the solar thermal drive jet sputtering multiple-effect composite seawater desalination system comprises an evaporation tower 1, an expansion jet type atomization evaporator 2 is arranged in the evaporation tower 1, the expansion jet type atomization evaporator 2 is connected with a solar air pipe type thermal expansion heat collector 3, a surface sputter evaporator 4 which is arranged below the expansion jet type atomization evaporator 2 and can evaporate water drops sprayed by the expansion jet type atomization evaporator 2 into steam is arranged in the evaporation tower 1, the surface sputter evaporator 4 is connected with a solar air direct heating heat collector 5, and the upper part of the evaporation tower 1 is connected with a vaporized water condensation heat exchanger 6 capable of condensing the steam.

In operation, when sunlight continuously irradiates, seawater in the solar air pipe type thermal expansion heat collector 3 absorbs heat and expands, the temperature and the pressure gradually rise, and the seawater gradually enters a saturated state. When the set pressure of the pressure control electric valve 17 is reached, the electric valve is opened, seawater enters the evaporation tower 1 through the pipeline and passes through the expansion jet type atomization evaporator 2 to generate steam-water separation. The separated vaporized water enters the vaporized water condensing heat exchanger 6 upwards, and the water drops flow downwards to the surface sputtering evaporator 4.
In the process, firstly, the seawater sealed in the solar air pipe type thermal expansion heat collector 3 statically absorbs heat, and the seawater has pressure generated by volume expansion, has energy for doing work externally, and can generate certain kinetic energy without external power. The energy is released to the outside through the expansion jet type atomization evaporator 2 in the evaporation tower 1, and the physical phenomenon is 'gas-liquid separation'.
The solar air directly-heated heat collector 5, the surface sputtering evaporator 4 and the evaporation tower 1 form surface sputtering evaporation. In operation, when sunlight is continuously irradiated, air in the solar air direct-heating type heat collector 5 is heated, gradually expands and is transmitted to the air chamber of the surface sputtering evaporator 4 outwards and upwards, and the surface of the evaporator is heated, so that the surface of the evaporator has high temperature. When the liquid seawater separated by the expansion jet type atomization evaporator 2 drops on the surface sputtering evaporator 4, the water drops absorb part of heat instantly, gas-liquid separation occurs, and sputtering evaporation is completed. The separated fresh water vapor upwards enters the vaporization water condensation heat exchanger 6, and the separated concentrated water downwards flows to the concentrated seawater multi-effect heat exchanger group 20. In this process, the solar air directly-heated heat collector 5 absorbs heat, and according to the phenomenon of "heat rise", the air flows upward, directly heating the evaporation surface of the surface sputtering evaporator 4. Also it does not require any external driving force to achieve thermal energy transfer. Because the heat capacity of the air is small, the temperature of the inner cavity is much faster than the temperature rise speed of the solar air pipe type thermal expansion heat collector 3, and the evaporation surface of the surface sputtering evaporator 4 is much higher than the spraying temperature. This temperature difference satisfies the necessary conditions for sputter evaporation, and the higher the surface temperature of the surface sputter evaporator 4, the larger the temperature difference with the liquid, the better the sputter evaporation effect.

The corrugated evaporation surface 11 is characterized in that the evaporation area is increased, and the liquid density per unit area is reduced and the evaporation efficiency is improved when a certain injection amount is obtained. The baffle plates 12 function to increase the residence time of the liquid in the corrugated evaporation surface 11 and improve the evaporation efficiency.
