Solar-driven seawater desalination system and method

The invention discloses a solar-driven seawater desalination system and method, and belongs to the technical field of seawater desalination. The seawater desalination system comprises a dust remover, a fan, a dew point evaporator, a heat regenerator, a cooler, a solar pond, a circulating pump, a concentrated brine pump and a seawater pump; the dust remover, the fan, the dew-point evaporator, the heat regenerator, the cooler and the gas-liquid separation tank are sequentially connected through pipelines to form an air flowing system; the cooler, the solar pond, the seawater pump, the heat regenerator, the solar pond, the circulating pump, the dew-point evaporator and the concentrated brine pump are sequentially connected through pipelines to form a seawater flowing system. Through coupling of the solar pond and the dew-point evaporation system, the solar pond is used for absorbing solar radiation to provide a heat source for the dew-point evaporation system, so that green and low-carbon water resource producti
