Technical field
The present invention relates to the technical field utilizing solar energy to generate electricity and carry out desalination of sea water.
Background technique
The solar chimney power generation system mainly contains four parts such as solar chimney, thermal-arrest canopy, recuperation layer and turbine generation unit and constitutes.The thermal-arrest canopy of being made up of transparent cover and support is the center with the solar chimney, is circle-shaped distribution, and with the face of land recuperation layer certain distance is arranged.The heat insulation thermal-arrest canopy of printing opacity is equivalent to a huge glasshouse, and temperature raise after the face of land recuperation layer in it absorbed sun short wave radiation, and the air in the heating canopy; The absorption of air heat, temperature raises, and density reduces; Form density difference with the outer set border, thereby formed pressure difference.The chimney that plays the effect of negative pressure pipe has strengthened the inside and outside pressure difference of system, forms powerful upward flow and drives the separate unit Air Turbine Generator that places chimney bottom central authorities or be many small air turbine generation unit generatings that group shape is arranged.Because recuperation layer has absorbed a large amount of solar radiant energies daytime, night is continuous release heat still, can realize uninterruptable power generation.
Because the intrinsic power generation characteristics of solar chimney power generation system, promptly day and night fluctuation makes it lack the quality of thermoelectricity and peculiar adaptation load variations of water power and stable system.From the thermomechanics angle; In fact the solar chimney generation technology is still the solar thermal power generating; The solar energy heating canopy is the very low thermal source of temperature; This efficient that has just determined the solar chimney power generation system to be used for electrical production merely be difficult to improve, even also difficultly under very desirable situation obtain the conversion efficiency greater than 1%.Simultaneously, the solar chimney power generation system is taken up an area of bigger, and land use capability is lower.
Utilize solar energy to carry out the desalination of seawater, its energy utilization mode has two kinds.The one, the seawater phase transition process that the heat energy that utilizes solar energy to produce drives is still-process; The 2nd, the electrodialytic process that utilizes solar electrical energy generation to drive.The solar distilling technology is meant the heat of utilization from solar energy acquisition, adds hot sea water, makes evaporation of seawater produce phase transition process and forms water vapor, makes water vapor condensation and collection fresh water again.
Tradition solar energy distillation device water yield is all lower, and 3 reasons are arranged: the one, and the latent heat of condensation of steam is utilized again, has gone but be lost in the atmosphere through cover plate.The 2nd, the heat exchange pattern of natural convection in traditional solar energy distillation device, big limitations the raising of distilling apparatus thermal characteristics.The 3rd, seawater thermal capacity to be evaporated in traditional solar energy distillation device is too big, has limited the raising of running temperature, thereby has weakened the driving force of evaporation.Therefore, the water yield of solar distilling system be improved, above-mentioned three defectives must be overcome.Simultaneously, solar energy distillation device takes up an area of bigger, and land use capability is lower.
