风力增压联合海水淡化太阳能烟囱电站初探
|
摘要
建立风力增压联合海水淡化太阳能烟囱电站(WSSCPPCSD)的数学模型,以西班牙太阳能烟囱电站原型为基础进行数值模拟,并用对比的方法分别对太阳能烟囱电站(SCPP)、联合海水淡化太阳能烟囱电站(SCPPCSD)及WSSCPPCSD却有所降低,通过风力增压系统在烟囱出口提供64.5 Pa的负压,可使SCPPCSD量提高8.22 kg/h,太阳能综合利用率提高到13.2%。风力增压系统不仅能显著增加发电量,而且可提高淡水产出。
The mathematical model of wind supercharged solar chimney power plant combined with seawater desalination(WSSCPPCSD)was established. Based on the Spanish solar chimney prototype,the numerical simulation was carried out. Research and analysis of solar chimney power plant(SCPP),solar chimney power plant combined with seawater desalination(SCPPCSD) and WSSCPPCSD were conducted by contrast. The results show that,although SCPPCSD greatly improves the solar energy comprehensive utilization,the power generation is reduced. By providing a negative pressure of 64.5 Pa at the chimney outlet,the output power of SCPPCSD can increase 14.7 kW and the hour water production can increase 8.22 kg/h. Besides,the solar energy comprehensive utilization can increase to 13.2%. The wind supercharging system not only significantly increases the power generation,but also increases the freshwater production.
