Description
Technical Field
[0001] The present invention relates to the technical field of saline-alkali land improvement, and more specifically to a device and method for saline-alkali land improvement driven by solar thermal energy. Background Art
[0002] As a special type of soil, saline-alkali land has a high salinity and alkaline environment, which severely restricts the growth of crops and the effective use of land resources. Traditional treatment methods mostly rely on large amounts of fresh water flushing, which is not only costly, but also has the risk of water waste and secondary pollution. Therefore, this project aims to design a saline-alkali land treatment device based on the principle of photothermal water evaporation, which can promote soil salt migration and reduce soil alkalinity through efficient use of solar energy resources, thereby achieving effective treatment of saline-alkali land and sustainable use of land resources.
[0003] At present, there are many solutions on the market for improving saline-alkali land using solar energy. The core of most solutions is to leach saline-alkali soil and reduce the nicotine content of the soil by pumping out saline-alkali water. The invention patent with publication number CN116438963A provides a low-cost method for improving saline-alkali land. The core is to use the electricity generated by solar photovoltaic power generation or wind power generation to drive water evaporation, condensation and flow, but the working efficiency of photovoltaic power generation systems is usually only about 10%, and the use of electric heating to evaporate and reuse water is undoubtedly inefficient. The invention patent with publication number CN116062821A proposes a saline-alkali land eluent recovery device and recovery method based on photothermal evaporation. Its characteristics are that it uses solar energy to evaporate the water in the salt-containing eluent into the air, which can only recover salt and cannot efficiently use precious water resources. At the same time, the distance of transporting the eluent by capillary action is too long, which is bound to be inefficient. The invention patent with publication number CN115676945A provides a low-carbon desalination system that uses solar energy to achieve seawater desalination, but it can only be used as a supporting device for the saline-alkali land improvement system and cannot be used alone. The invention patent with publication number CN112645519A proposes a system and method for using solar energy to collect heat and dry tubes to remove alkali from saline-alkali land. The system is too complicated and costly.
