What is a Cooling Tower? Why Closed Circuit Cooling Towers Prevent Scale in Piping?
Cooling towers reject waste heat to the atmosphere by using water. Generally, cooling efficiency is based on the wet bulb temperature. Wet bulb temperature is crucial for the efficiency of a cooling tower as it integrates various scientific principles, including aerodynamics, thermodynamics, fluid dynamics, chemistry, biochemistry, and materials science. Common applications include the plastic injection industry, centrifugal furnace casting industry, refineries, petrochemical plants, chemical plants, and other industrial fields.
Principle of a Cooling Tower
Cooling towers remove waste heat from water by bringing hot water into contact with air, causing evaporation that cools the water. This process is enhanced by cooling fins, which increase the efficiency of heat transfer. The cooled water is then recirculated back into the industrial process.
Types of Cooling Towers
Cooling towers can be categorized based on the direction of air and water flow:
|
|
|
| Counterflow Cooling Tower | Crossflow Cooling Tower | Mixedflow Cooling Tower |
Common Issues with Cooling Towers
Cooling towers are known for their simple structure, low cost, and easy maintenance. However, common problems include:
- Scale generation
- Large water consumption
- Difficulty maintaining cooling water quality
What is a Closed-Circuit Cooling Tower?
A closed-circuit cooling tower features a coil heat exchanger that separates the cooling water into "internal water" and "external water". The internal water, used for machinery cooling, circulates in a closed loop, maintaining high water quality. The external water indirectly cools the internal water inside the heat exchanger coils, preventing dirt and scale from entering the system.
Structure and Working Principle
- Internal Water System: Stays clean, includes an internal circulation motor, cold water line, hot water line, and heat exchanger coil.
- External Water System: Cools down internal water indirectly, includes an external circulating pump, water distribution system, and water basin.
Structure and working principle of closed circuit cooling tower
| Water system | Water quality | Components | Main function |
|---|---|---|---|
| Internal water system | Always stay clean | Internal circulation motor, cold water line, hot water line, heat exchanger coil | Prevent scale deposits when the cooling process |
| External water system | Cooling water with dirt | External circulating pump, water distribution system, water basin | Cool down internal water indirectly |
