How to consider sand and wind protection for circulating water cooling towers
Thread Content
The existing recirculating water cooling plants located on the edge of deserts are designed with a cooling capacity of 3,000 cubic meters per hour; they use counterflow mechanical ventilation for cooling. The local parameters include 53 days of sandstorms per year, an average wind speed of 3.12 m/s, and an extreme maximum wind speed of 44 m/s. Could you please suggest some effective measures to address issues such as wind and sand protection as well as prevention of water loss? Thank you!
It would be possible to arrange the intake opening at an angle perpendicular to the direction in which wind and sand blow throughout the year, thereby reducing the entry of dust into the circulating water system. It could be designed to be completely sealed, but that might result in high costs. That’s just my guess.
Reducing the water drift rate can be achieved by improving the structure of the water collector； To prevent sandstorms, closed-type cooling towers can be used; their cost is slightly higher than that of open-type towers, but the economic, environmental, and social benefits they bring are significant and cannot be ignored.
1. If the cooling tower has not yet been built, the approach suggested for the 3rd floor can be considered, whereby the air intake is positioned at a perpendicular angle to the direction in which wind and sand prevail throughout the year； If it has already been built, grass can be planted around the cooling tower to reduce dust levels. 2. Install side filtration facilities to effectively filter out dust and other mechanical impurities. 3. Water loss due to drift can be minimized by using high-efficiency, low-resistance reinforced arc-shaped water collectors, reducing the water loss rate based on the circulating water volume to below 0.001%; this is achievable by major cooling tower manufacturers in China.
