How to prevent premature damage to cooling tower packing

　　Premature damage to cooling tower packing can directly reduce heat exchange efficiency, increase energy consumption and replacement costs. Its damage is often related to improper material selection, water pollution, lack of maintenance, abnormal operation, etc. Prevention should be taken from multiple dimensions:2nrCooling tower noise reduction treatment manufacturer

　　1、 Accurate selection: matching working conditions, laying a durable foundation2nrCooling tower noise reduction treatment manufacturer

　　Suitable materials and usage environment: Select the corresponding packing material according to the water quality and temperature of the cooling tower - if the water quality has high hardness or contains corrosive impurities, priority should be given to selecting PVC modified packing or FRP packing that is resistant to scale and corrosion, to avoid ordinary PVC packing being blocked or damaged due to scaling or corrosion; High temperature environments (inlet water temperature>45 ℃) require the use of high-temperature resistant fillers to prevent deformation and softening of ordinary fillers due to heat; In scenes with strong sandstorms or foreign objects invading, large-diameter and impact resistant fillers can be used to reduce impurity jamming and damage. ​2nrCooling tower noise reduction treatment manufacturer

　　Control the quality standards of fillers: select qualified products that meet industry standards, inspect the appearance of fillers, test their toughness and strength, and avoid using inferior recycled fillers; The same group of fillers should have uniform specifications to prevent installation misalignment and uneven stress caused by dimensional deviations. ​2nrCooling tower noise reduction treatment manufacturer

　　2、 Optimize water quality: reduce pollution, decrease corrosion and scaling2nrCooling tower noise reduction treatment manufacturer

　　Proper water quality pretreatment: Install filtering devices (such as quartz sand filters and bag filters) in the circulating water system of the cooling tower to intercept impurities such as sediment and suspended solids in the water, and prevent impurities from adhering to the surface of the packing material, blocking pores or scratching the packing material; If the water quality has high hardness, it is necessary to equip it with softening treatment equipment (such as ion exchangers) to reduce the content of calcium and magnesium ions and minimize the formation of scale. Scale will wrap around the packing, hinder heat exchange, and cause cracking of the packing due to expansion and compression. ​2nrCooling tower noise reduction treatment manufacturer

　　Regular water quality monitoring and treatment: Weekly testing of circulating water pH value (controlled at 7-8.5), turbidity (≤ 20NTU), corrosion rate and other indicators. If the pH value is too high or too low, timely addition of acid-base regulators; Add corrosion and scale inhibitors (such as polyphosphate agents) every month to suppress metal corrosion and scale formation. The dosage should be adjusted according to water quality parameters to avoid excessive use of the agents leading to packing pollution; Perform a system backwash once every quarter to flush away impurities and mild scale accumulated in the packing layer. During flushing, control the water pressure (≤ 0.2MPa) to avoid damaging the packing due to impact. ​2nrCooling tower noise reduction treatment manufacturer

　　3、 Standardized maintenance: timely investigation to avoid accumulated damage2nrCooling tower noise reduction treatment manufacturer

　　Regular cleaning and inspection: Stop the machine every 1-2 months to clean the debris on the surface of the packing material (such as fallen leaves, willow catkins, algae). Use a low-pressure water gun to rinse along the gap between the packing materials to avoid direct impact of high-pressure water flow on the packing material; Check the status of the packing layer every month, focusing on whether there is any damage, deformation, or misalignment. If a small amount of damaged packing is found, it should be replaced in a timely manner (the replacement should be consistent with the original packing specifications and tightly spliced) to avoid expanding the scope of damage; Check the support structure of the filling material (such as brackets and crossbeams) every six months. If there is looseness or corrosion, tighten or anti-corrosion treatment should be carried out in a timely manner to prevent the collapse and damage of the filling material caused by support failure. ​2nrCooling tower noise reduction treatment manufacturer

　　Avoid damage caused by improper operation: During maintenance, it is forbidden to step on the filling layer (temporary support platforms need to be built) to prevent deformation of the filling due to the weight of personnel; When cleaning or replacing the packing, avoid scratching the surface of the packing with hard objects (such as screwdrivers, wrenches) to prevent scratching and damaging the structure; Soft lifting straps are required for hoisting fillers. It is forbidden to directly tighten the fillers with ropes to avoid local stress damage. ​2nrCooling tower noise reduction treatment manufacturer

　　4、 Reasonable operation: Control operating conditions and reduce abnormal losses2nrCooling tower noise reduction treatment manufacturer

　　Stable operating parameters: To avoid long-term overload operation of the cooling tower, adjust the inlet water volume and fan speed according to the load demand, and prevent excessive water volume from impacting the packing (causing packing displacement and damage) or excessive air volume from causing dry burning of the packing; Control the inlet water temperature within the tolerance range of the packing material (ordinary PVC packing ≤ 40 ℃, high-temperature packing ≤ 60 ℃), to avoid softening and deformation of the packing material caused by overheating. ​2nrCooling tower noise reduction treatment manufacturer

　　Dealing with adverse working conditions: In thunderstorm weather, if the cooling tower lacks rain protection measures, it is necessary to reduce the amount of water intake appropriately to avoid excessive rainwater washing away the filling material; In low temperature environments during winter, if the cooling tower is shut down, it is necessary to thoroughly drain the accumulated water in the packing layer to prevent freezing, expansion, and cracking of the packing; If there are pollution sources such as dust and oil fumes in the surrounding area, a dust screen should be installed at the inlet of the cooling tower, and the dust screen should be cleaned regularly to reduce the adhesion of pollutants to the packing. ​2nrCooling tower noise reduction treatment manufacturer

　　5、 Properly stored: protect spare fillers to prevent pre damage2nrCooling tower noise reduction treatment manufacturer

　　Spare fillers should be stored in a dry, ventilated, and dark indoor environment, avoiding direct sunlight, moisture, and dampness; When storing, it should be stacked horizontally, with a stacking height not exceeding 1.5 meters, and a soft tray should be placed at the bottom to avoid long-term compression and deformation of the filling material; Different specifications and materials of fillers should be stored separately and labeled to prevent mixing or accidental handling that may cause damage after installation.2nrCooling tower noise reduction treatment manufacturer
