Combined Flow Closed Cooling Tower
Closed Cooling Tower is operated by circulating water or fluid, which is divided into two closed loops.
1. Circulation in the tower: the circulating water or fluid passes through the hot zone environment. After the water temperature rises, it enters the surface cooler in the tower, and the heat is sent to the environment outside the tower through the surface cooler and ventilation fan. The cooled circulating water or fluid is sent to the heat source by the water pump.
2. Circulation outside the tower: the spray water is sent to the spray system by the water tank through the water pipe. After spraying, the spray water first exchanges heat with the filler, so that the spray water can be cooled rapidly. At this time, the water contacts the surface of the surface cooler for heat exchange. Part of the hot steam is discharged through the ventilation fan, and the cooled spray water drops to the water tank for secondary circulation to form an external circulation for cooling.

June 25, 2013, bidding management center of State Grid Corporation of China bid to win the bid: Xuji Group (domestic enterprises dynamic) in Zhoushan flexible flexible DC transmission major scientific and technological demonstration project successfully won the Yangshan converter station and Si reef exchange Flow station all valve and valve refrigeration system equipment contract. Flexible DC is a new generation DC transmission technology (valve, water pump) with voltage source converter as the core. It is the commanding height in the field of power electronic applications in the world today. Compared with conventional DC, flexible DC has the advantages of fast response speed, flexible operation mode, Small and other unique advantages for urban power grids, renewable energy grid, island power supply, power transactions. Flexible multi-terminal DC refers to more than two ends of the flexible DC project, can give full play to large-capacity, long-distance, multi-point transmission advantages. Zhoushan flexible multi-terminal DC transmission demonstration project is invested by State Grid Corporation of major scientific and technological demonstration project, is the world's first five-terminal flexible DC transmission project. It is understood that the dynamic investment of Zhoushan 4.2 billion yuan, the new 5 ± 200kV converter station, the new line of 140.4 km, of which 129 km of submarine cables, and the construction of the corresponding supporting AC transmission station project. The construction of Zhoushan flexible flexible DC transmission project will greatly enhance the scientific and technological level and the intelligent level of Zhoushan Power Grid, enhance the reliability and operational flexibility of power supply, and greatly enhance the access to new energy of Zhoushan Island. The strength of the major demonstration and display, is China's smart grid and DC transmission technology a major breakthrough. The successful bidding of Zhoushan flexible DC major science and technology demonstration project, the successful bidder of converter valve and valve cooling equipment, symbolizes Xuji Group made a major breakthrough in the field of flexible DC transmission technology and engineering application, greatly encouraging and encouraging morale. Consolidate Xu Ji's leading position in the field of HVDC transmission and provide a solid market (valve, water pump) foundation for Xu Jixian's faster and better development in the field of high voltage and large capacity flexible HVDC transmission.
