Abstract
Convection towers which are capable of cleaning the pollution from large quantities of air, of generating electricity, and of producing fresh water utilize the evaporation of water sprayed into the towers to create strong airflows and to remove pollution from the air. Turbines in tunnels at the skirt section of the towers generate electricity, and condensers produce fresh water.
Claims7
An updraft convection tower for cleaning polluted air, generating electrical power, and producing fresh water comprising:
- a structure defining a tower section having a top and a bottom, and a skirt section connected to and below said bottom section containing a plurality of individual tunnel sections;
- solar heating means in said skirt section for preheating air in said plurality of individual tunnel sections and for helping to create a flow of said air through said structure;
- a plurality of first water sprayer means disposed in said skirt section for removing pollution from said flow of air through said structure and for increasing relative humidity in said structure;
- a plurality of turbine motor/generator means disposed in said plurality of individual tunnel sections for initiating said flow of air through said structure and for generating electrical power once said flow of said air through said structure is established;
- and
- a second water sprayer means located in said tower section for producing water drops which collect mist particles in said flow of said air through said structure.
