A solar power generation and seawater desalination device combining condenser and wind turbine
ActiveCN106698567BPlay a warm-up roleAchieve outputGeneral water supply conservationSeawater treatmentWind drivenLiquid water
The invention discloses a solar power generation and seawater desalination device of combining a condenser and a wind turbine. A bottom groove of a seawater heat storage layer absorbs solar radiation to heat seawater, wherein seawater is evaporated into water vapor to be carried by airflow flowing inside from an inlet of a heat collector, wet hot air enters the condenser at the bottom of a chimney through the heat collector, the temperature of the wet hot air in a heat exchange wall surface is reduced, the separated liquid water is collected by a fresh water storage pool to improve the seawater desalination effect; the heat exchange air drives a turbine motor to rotate and work under the effect of a chimney effect; the turbine motor consumes most of pressure potential energy and one part of kinetic energy of the airflow and the remaining small part of pressure potential energy and kinetic energy are used for driving the airflow to escape towards the outlet of the chimney; and upper-air wind drives blades of a ventilator to rotate when blowing the blades of an H-shaped vertical axis wind turbine to rotate, and the inner and outer pressure difference of the chimney is further increased through negative pressure generated by the rotating blades of the ventilator, so that emission of working hot airflow in the chimney is accelerated and the chimney effect is strengthened.
