新型太阳能溶液再生装置性能研究

Based on improving conventional solar collector/regenerator, a novel air pretreatment solar collector/regenerator was put forward, which is very suitable for liquid regeneration under high humidity climate. It is found by experiment that the higher inlet temperature of liquid is preferable to raising regeneration efficiency, particularly the regeneration efficiency is more than 1.0 when the inlet temperature of liquid exceeds 60℃. The decrease of inlet concentration of liquid can be in favor of liquid regeneration and the regeneration efficiency reaches stability along with the fall of concentration of liquid. On the theoretical study of solar air pretreatment collector/regenerator, the elevation of liquid and air mass flow rate can almost increase water evaporation rate one time, and the variation of ESP can enhance the evaporation rate 20～30% at maximum.
