Problems solved by technology
Its biggest disadvantage is: due to the large surface temperature difference, seawater is very easy to scale on the inner wall of the vacuum tube, resulting in a rapid decline in thermal efficiency
Its obvious shortcomings: first, the forced power circulation needs to consume a large amount of electric energy; second, the long-length circulation pipeline has large heat loss and low thermal efficiency of the system; third, high-temperature-resistant circulating medium is required, and the investment in system equipment is large ,high cost

The invention belongs to the technical field of seawater desalination, in particular to a solar thermal driven jet sputtering multi-effect composite seawater desalination system. Including an evaporation tower, the evaporation tower is provided with an expansion jet atomization evaporator, the expansion jet atomization evaporator is connected with the solar air tube heat expansion heat collector, and the evaporation tower is provided with A surface sputtering evaporator located below the expansion jet atomization evaporator and capable of evaporating the water droplets ejected from the expansion jet atomization evaporator into steam, the surface sputtering evaporator and the solar air direct heat collector Connected, the upper part of the evaporation tower is connected with a vaporized water condensing heat exchanger capable of condensing steam. The advantage is that it does not need to be driven by a circulating pump, relying on volume expansion pressure for jet flash evaporation, using free fall for sputtering evaporation, using gas-liquid heat exchange for surface evaporation, and multi-stage heat exchange for heat recovery.
Description
technical field [0001] The invention belongs to the technical field of seawater desalination, in particular to a solar thermal driven jet sputtering multi-effect composite seawater desalination system. Background technique [0002] As we all know, the liquid is heated to produce vapor-liquid separation, and the gas-liquid separation of sewage can obtain higher quality water. This method is commonly known as "distillation purification". The use of vacuum tube solar energy as a heat source for seawater desalination is recognized as one of the most energy-efficient methods. There are two common modes of solar heating of liquids: direct heating and indirect heating. Common household vacuum tube solar water heaters belong to the direct heating mode. [0003] A solar module for directly heating seawater for evaporation, the vacuum tube is directly filled with seawater, and the seawater directly absorbs heat through the inner wall of the vacuum tube. According to the principle ...
