Central air conditioning cooling tower maintenance and cleaning

  The cooling tower is exposed to the outside for many years, and the fan’s adsorption power is very strong, so that a large amount of sand and dirt will enter the tower. Long-term operation will slowly reduce the cooling capacity of the cooling tower. The water outlet of the water distributor is easily blocked and mud Sand and dirt can also easily enter the cooling water system, which will directly affect the normal cooling of the cooling water system. In order to prevent the above situation from happening, the cooling tower must be cleaned regularly.VlTCooling tower noise reduction treatment manufacturer

  Cooling tower cleaning treatment plan process

  1. Rinse with waterVlTCooling tower noise reduction treatment manufacturer

  The purpose of water flushing is to flush out loose dirt such as dust, sand, shed algae and corrosive substances in the system as much as possible with a large flow of water, and to check the leakage of the system at the same time. After the flushing is qualified, drain the flushing water in the system.VlTCooling tower noise reduction treatment manufacturer

  2. Sterilization and algae cleaningVlTCooling tower noise reduction treatment manufacturer

  The purpose of sterilization and algae cleaning is to kill the microorganisms in the system and to peel off the biological slime attached to the surface of the equipment. After draining the flushing water, add a bactericidal and algaecide to the system for cleaning, and stop cleaning when the turbidity of the system reaches equilibrium.VlTCooling tower noise reduction treatment manufacturer

  3. Descaling and cleaning with cleaning fluidVlTCooling tower noise reduction treatment manufacturer

  The purpose of cleaning fluid cleaning is to use cleaning agent to dissolve the scale and oxide in the system and then dissolve it in water to rinse off. Add the cleaning agent to the central air-conditioning system and use the circulating pump to circulate the cleaning and drain at the highest point and the lowest point to avoid air resistance and guide shower blockage, which will affect the cleaning effect. During cleaning, the concentration of the cleaning solution, the concentration of metal ions (Fe2+, Fe3+, Cu2+), temperature, PH value, etc. should be checked regularly, and the cleaning should be finished when the concentration of metal ions tends to be flat.VlTCooling tower noise reduction treatment manufacturer

  4. Pre-filmingVlTCooling tower noise reduction treatment manufacturer

  The purpose of pre-filming is to form a complete corrosion-resistant protective film on the metal surface in the activated state after cleaning or the metal surface where the protective film is damaged.VlTCooling tower noise reduction treatment manufacturer

  Cleaning after cleaningVlTCooling tower noise reduction treatment manufacturer

  1. Clean the cooler evaporatorVlTCooling tower noise reduction treatment manufacturer

  After cleaning, the cooler and evaporator of the main engine should be opened and the cooler should be pulled through and flushed with a special pipe pipe. Because the water circulation system of the cooler is exposed to the atmosphere and the heat exchange temperature is high, the fouling condition of the cooler will be higher than that Other places are serious. If necessary, the cooler should be cleaned and descaled separately with an open circulation system to ensure that each copper pipe in the cooler is unblocked. Rinse the evaporator with high-pressure water to thoroughly wash away the impurities deposited in the evaporator. If necessary, clean the evaporator with a separate external circulation system.VlTCooling tower noise reduction treatment manufacturer

  2. Cooling tower cleaningVlTCooling tower noise reduction treatment manufacturer

  Since the cooling tower is exposed to the atmosphere, a large amount of sand, algae, etc. will adhere to the surface of the cooling tower filler during operation. If it is not cleaned up, these dirt will be washed into the cooler in the future operation, resulting in heat exchange copper in the cooler The blockage of the pipe affects the heat exchange effect, so the cooling tower must be thoroughly cleaned.VlTCooling tower noise reduction treatment manufacturer
