rcc Cooling Tower

详情

In a counter-flow cooling tower the air moves vertically upwards through the fill while waterfalls vertically downwards. Film type fill is used and is suitable for all cooling load applications, however, it is more suitable for the application where cold water temperature is critical and water quality is good. These cooling towers are made of RCC construction. Film type fill is made of PVC for normal water applications. These cooling towers are fitted with the fills of wider flute so that it can withstand most of the industrial water. The film type fill should be avoided for the applications where water has traces of oil and contaminated water. In the case of contaminated water PVC 'V' bars and grid can be used. Cooling towers are fitted with high efficiency mechanicals such as axial flow fans, gear boxes and drive shafts.
 
RCC Induced Draft Cross-flow
 
In a cross-flow cooling tower air moves through the fill horizontally and water falls vertically. The fill used is splash type fill and is suitable for cooling all load applications; however, it is more suitable for the application where water has higher suspended solids which can be a problem for film fill cooling tower operation. These cooling towers are made of RCC. For high temperature applications the splash fill is made of chemically treated timber whereas for normal temperature applications it is made of PVC.
