Construction steps and precautions for scale cleaning of closed cooling tower coils

  China trlon air conditioner previously introduced the cooling tower scale cleaning program and advantages for you. If this is the case, you must be very curious to know the construction steps and common problems of the closed cooling tower coil scale cleaning, so today I will take you to understand the relevant knowledge in this area .xQUCooling tower noise reduction treatment manufacturer

  The cleaning methods of the cooling water system can be divided into two categories: physical cleaning and chemical water treatment; physical cleaning methods include brushing, blowing, cleaning, back cleaning, scraper cleaning, high-pressure water jet cleaning, etc. When carrying out physical cleanup, people often cooperate with chemical water treatment; the chemical method is mainly to add drugs to clean up drugs.xQUCooling tower noise reduction treatment manufacturer

  For cleaning, the thickness of the dirt is more than 3.4mm, and it has been cleaned by people for 24 hours.xQUCooling tower noise reduction treatment manufacturer

  Trlon empty detailed cleaning process has the following points:xQUCooling tower noise reduction treatment manufacturer

  1. Manual cleaning, use high-pressure water guns to remove sludge, dust and other contaminants in water towers and pools, and then discharge waste water (Note: Before adding chemicals to clean up the drugs, the waste in the system can be more strongly used. (The drug touches the surface of the machine and equipment);xQUCooling tower noise reduction treatment manufacturer

  2. The water flow of the cooling water system is adjusted to a low safe water level (the water flow is enough for repeated cleaning). Add XQ-103 descaling agent 20kg~30kg per cube. Add the descaling agent to the circulating water of the cooling tower to carry out repeated operations. Check the pH value for about 1-2 hours after repeated. The pH value of the water is maintained at 1~1.5. If the pH value is greater than 2, a descaling agent must be added (so buy more when purchasing to prevent insufficient ), until the PH value is always maintained at 1-1.5, the scale cleaning is over. The cleaning time is usually within 12-24 hours, and drugs can be added according to the specific conditions of the coil.xQUCooling tower noise reduction treatment manufacturer

  3. Internal circulation to clean the dirt in the cooler: first connect the water inlet and outlet connectors of the cooler to the prepared circulating water pump, and the capillary tube on the intelligent water return water device is connected to the pump group in the stainless steel circulating water tank. On medicine.xQUCooling tower noise reduction treatment manufacturer

  4. Clean the surface scale of the external circulation cooler. After the water level in the s collection tank and the medicine are prepared according to the proportion, the cleaning staff can observe the transformation status of the medicine and the cooler at any time, and adjust the dosage of the medicine appropriately.xQUCooling tower noise reduction treatment manufacturer

  5. After cleaning, use tap water repeatedly to clean the remaining dirt.xQUCooling tower noise reduction treatment manufacturer

  6. Usually people suggest that the water circulate for 12-24 hours during scale cleaning, and increase or decrease appropriately according to the thickness of the scale. After the operation is over, the water is emptied and cleaned with clean water, and then it will operate normally when filled with water. (Plus 3‰ of XQ-301 pre-filming agent for pre-filming, to ensure that the pipes of machinery and equipment lay a good foundation for normal maintenance.xQUCooling tower noise reduction treatment manufacturer

  Frequently asked questions about scale cleaning of closed cooling towers:xQUCooling tower noise reduction treatment manufacturer

  (1): Clean up the waste and residue in the external circulation tank before cleaning.xQUCooling tower noise reduction treatment manufacturer

  (2): The cleaning time is usually within 12-24 hours, and drugs can be added according to the specific conditions of the coil.xQUCooling tower noise reduction treatment manufacturer

  (3): When cleaning, it can be washed with water immediately after touching the skin.xQUCooling tower noise reduction treatment manufacturer

  (4): After cleaning, drain the cleaning fluid. It can be used normally if the equipment is cleaned once or multiple times in the pool with water.xQUCooling tower noise reduction treatment manufacturer

  Closed cooling tower water body maintenance:xQUCooling tower noise reduction treatment manufacturer

  After the pre-filming is realized, the solution of the water treatment agent changing from a high concentration to a low concentration is called a usual solution. The usual solution includes usual dosing and analysis and testing.xQUCooling tower noise reduction treatment manufacturer

  (1) Add XQ-303 corrosion and scale inhibitor every week to soften the water body, inhibit the generation of scale, and have the effect of inhibiting scale. At the same time, it can also produce a protective film on the metal surface to reasonably inhibit metal corrosion;xQUCooling tower noise reduction treatment manufacturer

  (2) In addition, XQ-106 antiseptic algicide needs to be added every week, which can kill heterotrophic bacteria, iron bacteria and algae, avoid pathogens, algae and other microorganisms from causing corrosion and blockage to the facility, and improve the working efficiency of the circulating water system;xQUCooling tower noise reduction treatment manufacturer

  (3) Adjust the formula or dosage of the drug according to the changes in water body and temperature;xQUCooling tower noise reduction treatment manufacturer

  (4) The cooling water system is sampled to conduct water body tests every month, and the test reports are given.xQUCooling tower noise reduction treatment manufacturer

  The above are the construction steps and precautions for the scale cleaning of the cooling tower coils. If you have any questions or needs in this regard, you can call us for consultation.xQUCooling tower noise reduction treatment manufacturer
