The necessity of regular replacement and cleaning of cooling tower packing

Cooling tower packing with a high cost-effectiveness ratio can be used for a longer period of time, and it also relies on our daily maintenance and cleaning. When using or cleaning for a long time, the cooling tower packing will be replaced. The following is the cooling tower packing replacement process, hoping to be helpful to everyone.
Cooling tower packing replacement process:

1. Before construction, maintain other machinery and equipment on site, carry out necessary protection, and list them on the market. Raw materials for laying wooden flooring to prevent F-water in construction.
2. Remove old fillers. Turn off the power supply of the motor switch, remove a part of the pressure leg of the cooling tower packing, remove the old packing, clean up the waste from the tower body, and keep it clean on the spot.
3. Fill up the new packaging. Adhere the cooling tower packing and ensure that the packing points are in contact with the same level surface during the interval of adhesive solidification. Ensure that the packing points are evenly supported and inseparable throughout the entire process of Z-suppression.
4. Clear the tower body. Clean up the dust and waste inside the cooling tower, stack the packing materials in sequence inside the cooling tower, strictly prohibit trampling and squeezing, ensure that each pile of packing materials is neat, ensure that the packing materials are seamlessly connected to the tower corners and the tower center, and are difficult to stack. The CES interval shall not exceed 2mm. Repair and reinforce the filling part of the cooling tower with X structure.
5. The assembly line block should be assembled in the left and right directions. The top of each layer's wall should be leveled, the layers should be cleaned and tidy, and debris should be eliminated.
6. During installation, maintenance, and other work, it is necessary to carry out production and processing of fillers, and practical operations must be carried out on tablet computers. It is prohibited to trample on fillers.
7. During the entire construction process, it is prohibited to carry out electric welding on the filling material. If necessary, fire safety measures must be taken.

The cooling tower packing should be replaced irregularly after 4 years of use to ensure the normal working efficiency of the cooling tower. Over the years, there has been aging phenomenon, and some packing has fallen off, resulting in a decrease in the heat transfer capacity of the cooling tower. Affects the operational efficiency of refrigeration units and consumes a large amount of energy. At the same time, the broken cooling tower packing enters the copper tubes of the condenser of the unit with the operation of the cooling water pump. In addition, the new cooling water treatment agent (hydroxycarboxylate) currently used has a strong function of peeling off rust, resulting in blockage of the copper tubes of the condenser of the unit.

If uneven water distribution is found during the operation of the cooling tower, efforts should be made to eliminate the cause in a timely manner, usually due to blockage of the water distribution pipe and detachment of the nozzle. The accumulated dirt in the cooling water tank and cooling tower packing should be removed in a timely manner, usually once every time it is stopped. When algae growth is found in the circulating water, impact chlorination should be carried out to ensure a residual chlorine concentration of 4mg/L or bleaching powder treatment in the water for a short period of time. The turbidity and water volume of the inlet and outlet water of the fiberglass cooling tower should be included in the operation records of the cooling tower to accumulate maintenance and management data, and serve as a technical basis for maintenance and improvement of the cooling effect.

The selection of outdoor transition temperature point for cooling tower cooling mode is directly related to the system cooling hours. Assuming that the required water humidity for the air conditioning terminal is determined to be 12.7 ℃ through calculation. Considering the cooling amplitude of the cooling tower, the heat loss of the pipelines and heat exchangers, etc., which causes the water temperature to rise by 4.5 ℃, it can be concluded that the cooling tower cooling mode can be switched when the outdoor wet bulb temperature is equal to or lower than 8.2 ℃.
