太阳能雾化脱盐系统热能利用率的研究

在构建太阳能雾化脱盐系统的基础上对该系统处理浓盐水的热能利用率进行了研究,考察了辐照值、空气流量、气水比等因素对系统热能利用率的影响。结果表明,系统的热能利用率随着辐照值的升高呈现减小趋势,随着气水比、空气流量的增大呈现先增大后减小的趋势。系统的热能利用率与空气流量存在二次抛物线关系。

Study on the heat energy utilization rate of the solar energy pulverization desalination system

Based on the esta blishment of solar energy pulverization desalination system ,the heat energy utilization rate of concentrated brine treated by this system has been studied. The influences of the factors ,such as irradiation values,air flow,gas water ratio,etc. on the heat energy utilization of the system are investigated. The results show that the heat energy utilization rate of the system presents a tendency of decrease with the increase of irradiation va-lues;and the heat energy utilization of the system also presents a tendency of increase first,and then decrease,with the increase of gas water ratio,and air flow. There is a quadratic parabolic relationship between the heat energy utilization rate of the system and the air flow.
