Solar chimney-based liquid desiccation system with a thermally-regenerating desiccator

A solar chimney-based desiccation system comprising:

• a solar collector with a surface area to accumulate and absorb solar radiation and convert the solar radiation into thermal energy, wherein the solar collector heats a quantity of air coming into the solar collector through a solar collector entrance;
• an embedded desiccator with an internal space to deposit a liquid solution inside and operatively connected to the solar collector to receive a solar-heated quantity of air from the solar collector through a solar collector-to-desiccator pipe, wherein at least a portion of the liquid solution is vaporized after contact with the solar-heated quantity of air, which is directed into the embedded desiccator, and wherein the embedded desiccator additionally incorporates a heat-absorbing exchanger and at least one of a fluid collection pathway, a pooling collector, a pump element, and a loop-back pipe to improve a fluid evaporation efficiency of the solar chimney-based desiccation system;
• a heated chimney operatively connected to the embedded desiccator to receive and expel a vapor-enriched quantity of air containing vapors from the liquid solution to an external environment outside the solar chimney-based desiccation system, wherein an interior surface of the heated chimney is heated above a dew point of the vapors to prevent reflux and condensation of the vapors alongside the interior surface of the heated chimney, as the vapors rise through the heated chimney;
• and
• a liquid recovery condenser system operatively connected between the embedded desiccator and the heated chimney, wherein the liquid recovery condenser system contains a cold internal surface area to cool the vapor-enriched quantity of air containing the vapors coming out of the embedded desiccator but before entering the heated chimney, wherein at least a portion of the vapors are condensed as liquid in a liquid collection container inside or operatively connected to the liquid recovery condenser system.

A solar chimney-based desiccation system comprising:

• an embedded desiccator with an external air entrance to receive a quantity of unheated external air and an internal space to deposit a liquid solution inside, wherein at least a portion of the liquid solution is vaporized after contact with the quantity of unheated external air to become a vapor-enriched quantity of air, which is then directed into a solar collector operatively connected to the embedded desiccator, and wherein the embedded desiccator additionally incorporates a heat-absorbing exchanger and at least one of a fluid collection pathway, a pooling collector, a pump element, and a loop-back pipe to improve a fluid evaporation efficiency of the solar chimney-based desiccation system;
• the solar collector with a surface area to accumulate and absorb solar radiation and convert the solar radiation into thermal energy, wherein the solar collector heats the vapor-enriched quantity of air coming from the embedded desiccator;
• and
• a heated chimney operatively connected to the solar collector to receive and expel a solar-heated and vapor-enriched quantity of air containing vapors originating from the liquid solution to an external environment outside the solar chimney-based desiccation system, wherein an interior surface of the heated chimney is heated above a dew point of the vapors to prevent reflux and condensation of the vapors alongside the interior surface of the heated chimney, as the vapors rise through the heated chimney.
