Industrial circulating cooling tower
Industrial circulating cooling tower is the key equipment used for cooling circulating water in industrial production, through the heat exchange between water and water to realize heat dissipation, to ensure stable operation of the system.
Closed circulating water cooling tower is through the closed heat exchange structure to realize the circulating medium efficient cooling equipment, with water saving, energy saving and to ensure that the water quality is clean and so on, its core principles and key technologies are as follows:
The core principle
I.Double circulation system design
-Internal circulation: cooling medium (water, oil, etc.) in the closed pipe flow, completely isolated from the outside world, to avoid contamination and evaporation losses
-External circulation: spray water on the outside surface of the heat exchanger tube to form a water film, through evaporation and heat absorption to take away the heat from the pipe wall.
Air-assisted heat dissipation: fan-driven air flows through the outer surface of the heat exchanger tube, strengthening convection heat transfer and discharging hot and humid steam.
II. Energy-saving and water-saving mechanism
-When the external temperature is low, the spray system can be turned off, and only air cooling through the finned tube dissipates heat (dry cooling mode), which reduces water consumption.
-Spray water recycling, only a small amount of evaporation loss needs to be replenished, the overall water consumption than the open cooling tower to reduce more than 60%.
Key structures and components
subassemblies | Functional Description |
Coil Heat Exchanger | Core heat transfer components, the material is mostly selected stainless steel or copper, corrosion resistance and high heat transfer efficiency. |
spray system | Evenly spray water film to the coil surface, combined with fan airflow to accelerate evaporation and heat dissipation. |
water receiver | Reduces water waste by intercepting water droplets in hot, humid air |
control system | According to the ambient temperature and water temperature automatically switch dry cooling / wet cooling mode, to realize intelligent energy-saving regulation. |
Typical Application Scenarios
