摘要
高压泵是反渗透海水淡化系统中的主要耗能设备。根据风电海水淡化耦合系统的供电特点,分析了高压离心泵和柱塞泵在变功率运行条件下流量和扬程的变化特点,解析了高压泵并联运行的功率、流量分配,认为小规模风电反渗透海水淡化耦合系统的高压泵选柱塞泵更为合适。
High pressure pump consumes most of energy in the membrane desalination system. According to the characteristics of power supply of wind energy, the shift of flux and head of high pressure centrifugal pump and plunger pump was analyzed under variable power operation. Also, the distribution of flux and power of multipledhigh pressure pumps were calculated. Combined with the operating cost of centrifugal pump and plunger pump, the plunger pump is fitter to membrane desalination in wind powered seawater desalination system in small scale.
