Renovation of packed cooling towers

Where is the original poster from? I’m not sure whether the renovation project for the cooling tower has been carried out or not. We specialize in fillless towers; please provide me with your contact information and the parameters of the tower, and I will prepare a detailed plan for you.

The improvement efforts based on the existing structure are not effective; it is necessary to raise the cooling tower, otherwise the settling cooling height will be insufficient.

Features of the BK series energy-saving spray cooling towers: (Please discuss and verify these features.) For detailed information, please send an email to liutaoandzdy@sina.com. 1. Large cooling temperature difference, low resistance, and small deviation: Thanks to the low-pressure, high-efficiency atomization device that sprays water into tiny particles of 0.7–1.0 mm in size, the specific surface area is much larger than that obtained when water is dispersed into a film form by packing materials. This results in a larger surface area for gas heat and mass transfer, as well as uniform water distribution. It avoids uneven cooling temperature distribution caused by dead zones, beam currents, and channeling resulting from the aging, deformation, cracking of the packing, as well as sediment blockages; therefore, its cooling efficiency is significantly better than that of a packed tower. Since the packing is removed in the packing-free spray cooling tower, the system resistance of the tower is reduced to 50% of its original value. With the fan remaining unchanged, the fan’s performance curve shows that the air flow rate increases to 120% of the original level. The gas-to-water ratio also increased to 120% of the original value, resulting in a cooling temperature difference that is 2–5°C higher than that of a newly built packed tower. 　　　2. Large cooling water volume: Under the same fan conditions and temperature difference, the resistance of the fill-free spray cooling tower system is reduced, the air flow rate increases, and the cooling water volume is more than 20% higher than that of a fill tower ； 　　　3. Low operating costs and significant energy-saving effects: The operating pressure of the high-efficiency low-pressure atomization device is 0.16 Mpa lower than that of 0.2 Mpa in packed towers, which also results in a reduced power requirement for the accompanying water pumps. Moreover, the tower resistance is only 50% that of a packed tower; when the cooling water volume and the fan remain the same, the power required of the fan motor is reduced to 70% of that in a packed tower, resulting in significant energy savings. Moreover, the costs for cleaning, replacing the packing, and the water distribution nozzles have been eliminated. 　　　4. Low noise level: 8 dB lower than that of packed towers. The reduced static pressure of the fan results in a noise level in the cooling tower that is 8 dB lower than that of packed towers. 　　　5. No water splashing occurs, resulting in excellent environmental benefits: The special water collector developed by our company prevents water splashing, thus avoiding losses of liquid water as well as losses of chemicals present in the cooling water. This not only protects the ecological environment but also saves water resources. 　　　6. Using a special spraying device to address the problem of blockages in the equipment of the production system: By utilizing the spraying device as a cooling element, the issues associated with traditional packing towers – such as the aging, deformation, cracking, and blockage of the packing material, as well as the obstruction caused by packing fragments to the equipment and pipelines in the production system, along with uneven water distribution due to channeling or concentrated flow within the tower – are completely resolved. 　　　7. Longer operating cycle compared to packed cooling towers: After operating for a certain period of time, the packing in packed cooling towers ages, deforms, and cracks, which causes the water flow within the tower to take on channelized or concentrated forms; as a result, the cooling efficiency of hot water is significantly reduced. In spray cooling towers, spray devices are used to distribute the spray evenly within the tower, and their cooling effect does not suffer any decline over time as the tower operates, thus ensuring that the temperature of the hot water remains reduced.
