Abstract
The invention relates to an anti-blocking seawater desalination device based on graphene filtering, comprising heating device, solar heat-collecting device, fresh water condensation heat-exchange device and thermal-expansion and cold-shrinkage control valve mechanism; the heating device can fully heat and distill seawater, the sprayed seawater is distilled by graphene heat-conduction layers to improve the distillation efficiency and avoiding blocking; the distilled water vapor enters into fresh water condensation heat-exchange device to exchange heat with seawater, increasing the seawater temperature, making full use of the heat in water vapor, and increasing water vapor condensation speed; the distilled concentrated seawater enters into the thermal-expansion and cold-shrinkage control valve mechanism, the flow of seawater entering into the heating device is controlled by the concentrated seawater temperature, when the temperature is too high, the flow of the seawater entering into the heating device increases, and when the temperature is too low, the flow decreases.
