cooling tower parts & Functions

தயாரிப்பு விளக்கம்

Cooling towers, essential for heat dissipation, consist of key parts likebasins, fills, nozzles, and drift eliminators, each playing a crucial role in the cooling process, and can vary significantly in size and shape.

Key Parts and Functions:

• Cooling Tower Basin:

• Collection Basin:Located at the bottom, it collects cooled water and directs it to the pump suction line or sump.

• Distribution Basin:An elevated, shallow-type basin that distributes hot water to the tower via holes in the basin floor.

• Cold Water Basin:Serves as storage for cold water and provides the main structure and foundation for the cooling tower.

• Cooling Tower Fills (Heat Exchange Surface):

• These are the surfaces where water and air interact, facilitating heat exchange.

• They are designed to maximize contact between air and water for efficient heat dissipation.

• Cooling Tower Nozzles:

• These are affixed to the hot water pipes and spray water onto the fills.

• They contribute to the enhancement of the cooling effect by dispersing water across a broad area.

• Cooling Tower Drift Eliminator:

• These capture large water droplets from the air stream, preventing them from being carried away.

• Other Important Parts:

• Fans:Driven by motors, they circulate air through the tower to promote evaporation and heat transfer.

• Gearbox:Slows down the rotational speed from the motor to the fan.

• Driveshafts:Connect the motor and gearbox, transmitting power.

• Air Intake Louver:Blocks water splash-out, noise, and debris.

• Piping:Distributes water within the cooling tower.

• Float Valve:Maintains the right water levels inside the cooling tower.

Length and Width:

• Cooling towers come in various sizes, from small roof-top units to large hyperboloid structures.
• Hyperboloid towers can be up to 200 meters (660 ft) tall and 100 meters (330 ft) in diameter.
• Rectangular structures can be over 40 meters (130 ft) tall and 80 meters (260 ft) long.
• A cooling tower example is 21.65 m wide 36.9 m long 15.24m high.
