How to clean the dirt effect of closed cooling tower

How to clean the dirt effect of closed cooling tower

  Closed cooling tower is a machine which can reduce heat according to the heat exchange of flowing gas, spray water and circulating water. It is used in the fields of metallurgy industry, food processing, rubber products, plastic products, machinery and equipment, chemical industry and so on. The closed cooling tower will generate scale and dirt after being used for a long time. Then how should the scale and dirt of the cooling tower machine be removed?DalCooling tower noise reduction treatment manufacturer

  1. Acid-base neutralization method. When an acid and a base mix, it leads to an organic chemical reaction, an acid-base neutralization reaction, which produces water and sodium chloride, in which sodium chloride is often referred to as salt. This is because scale and dirt cover is relatively large and manual cleaning is more difficult. People generally choose to spray weak acid water to carry out neutralization. In similar cleaning circumstances, pure water is selected to open the circulation and carry out washing.DalCooling tower noise reduction treatment manufacturer

  2, cooling tower scale remover, cooling tower scale remover inside also has the corresponding weak acid, but also with some penetrant, corrosion inhibitor and other substances. It can dissolve high thickness scale and dirt faster, and it can naturally fall off under the force of water hammer. There are differences between open cooling tower and closed cooling tower when scale remover is used. The scale and dirt of closed cooling tower is mainly the surface of the centralized condenser. The condenser is a metal material, and strong acid will lead to corrosion.DalCooling tower noise reduction treatment manufacturer

  3, electromagnetic descaling, this kind of method is relatively novel, using the structure of the magnetic field change scale dirt, make scale dirt can't gather in a after oxidation, electromagnetic descaling is safe and reliable way at this stage, does not damage of metal materials in other electromagnetic descaling and can save a lot of cost, electromagnetic cleaner is mainly used in circular pipe used inside.DalCooling tower noise reduction treatment manufacturer

  The scale removal operation of closed cooling tower should be carried out frequently, but if stainless steel tube is used, it will not lead to this kind of situation. The surface oxidation treatment of stainless steel tube condenser, scale and dirt should not adhere to the surface, compared with copper tube, can prevent the cause of scale and dirt faster. In fact, the pool of the closed cooling tower is equipped with its own water, on the other hand, to ensure the sealing faster, and on the other hand, to reduce the water consumption. This also fully explains one of the major advantages of the closed cooling tower -- less water consumption and less water evaporation.DalCooling tower noise reduction treatment manufacturer

  In order to make the water collection and circulation of the pool normal, spray water pump, spray water circulation pipeline, water filling port and sewage outlet and other parts must be installed at the upper end of the closed cooling tower water quality. In this way, the water volatilization of the cooling tower is all the spray water in the collecting pool. Even if there is a small amount of water evaporation in the case of heat volatilization, it can also be carried out according to the water filling port directly connected to the tap water port, and the water filling port inside the floating ball valve is used to adjust the water filling volume.DalCooling tower noise reduction treatment manufacturer

  Next, according to the spray pump in the closed cooling tower, the water inside the pool is pressurized and supplied to the spray system, which sprays the water to the condenser. And some non-volatile cooling water will fall back into the pool, which is the whole process of the operation of the closed cooling tower pool.DalCooling tower noise reduction treatment manufacturer

  In comparison, the pool of open cooling tower is much simpler both in structure and in the whole process of operation, because it is an external hanging pool, so water can be added directly to the pool for circulation, but that also greatly increases the water consumption of the cooling tower.DalCooling tower noise reduction treatment manufacturer

  Not only that, but considering that the heated water in the open cooling tower evaporates into water molecules, it works very fast; In addition, the cooling tower does not adopt an effective method of water recovery, which leads to the problem of high water flow rate in the cooling tower, and correspondingly, the supplementary water in the cooling tower is also increased.DalCooling tower noise reduction treatment manufacturer
