Chinese fan development status
From January to December of 2007, China's fan and fan manufacturing industry realized cumulative industrial output value of 34,433,825 thousand yuan, an increase of 31.03% over the same period of the previous year; from January to October 2008, China's fan and fan manufacturing industry realized cumulative The total industrial output value was 39,704,575,000 yuan, an increase of 37.46% over the same period of last year.
In recent years, China's fan industry has developed a series of high-efficiency new types of fans, especially with the continuous digestion and improvement of imported technologies, power station fans for Shanggu, Shengu, Chengdu Electric Machinery, wind tunnel fans, Siping, re-entry high-temperature fans The industrial boiler fans of Beijing Xishan, Shengu and Shanggu have gradually gained users' approval, which has brought great economic results to the factory. However, there are still many kinds of inefficient old turbines in China that need to be replaced. The newly promoted turbines need to be further improved. Therefore, China should continue to improve the quality of wind turbine products and stabilize market demand. It must also actively introduce advanced technologies and improve technological development capabilities. With a brand strategy, it should vigorously explore the market and promote the development of wind turbine enterprises on an economic scale.
There are many areas that have not yet been involved or will be involved in China's wind turbine products. There will be more than 20 potential market areas such as comprehensive utilization of coal gangue, new dry clinker technological transformation projects, energy conservation in the metallurgical industry and comprehensive utilization of resources. Big development prospects.
The future development of wind turbines will further improve the aerodynamic efficiency, device efficiency and use efficiency of the wind turbines to reduce the power consumption; use axial fans with adjustable blades to replace large centrifugal fans; reduce the fan noise; improve the exhaust fan and fan The wear resistance of the shell; variable speed regulation and automatic adjustment.
Counter Current Cooling Tower has higher efficiency of the same volume, and offers larger water temperature difference. But it also comes with several disadvantages:
1.The unequal height between the air inlet and the water eliminator makes up the big Counter Current Cooling Tower and its high power consumption.
2.Meanwhile, the tower adopts nozzles to distribute water, which needs high pressure requirements and are easy to be blocked.
3.The entire tower body of the countercurrent tower is a closed structure, and it must be shut down when the equipment is overhauled or routinely maintained.
4.In addition, the rapid loss of water in the lower tank is very large, and it is easy to form water mist around the cooling tower, which is easy to cause the reproduction of legionary bacteria.
