What are the energy-saving technologies for closed cooling towers?

  There are many types of cooling towers: closed cooling towers, cross-flow cooling towers, silent cooling towers, etc. What are the energy-saving technologies of closed cooling towers?V3qCooling tower noise reduction treatment manufacturer

  A, countercurrent tower

  (1) The water is in the filling material in the tower, the water flows from top to bottom, and the air flows from bottom to top.V3qCooling tower noise reduction treatment manufacturer

  The countercurrent cooling tower has good heating function and is divided into three cooling sections: ①The space from the water distributor to the top of the filling material. The temperature of the water in this section is higher, so the heat energy can still be transferred to the air. ②The heat exchange section of filling material water and air. ③The water spraying section of the filling material to the sump space, where the water is cooled is called "tail effect". In the northern part of the country, the water temperature can drop to 1-2°C. In general, the countercurrent tower is about 20% smaller than the cross-flow tower in the same situation, and the heat exchange process of the countercurrent tower is more reasonable and high in cooling efficiency.V3qCooling tower noise reduction treatment manufacturer

  (2) The water distribution system of the closed cooling tower is not easy to be blocked, the water filling material is kept clean and not easy to age, the moisture backflow is small, and the antifreeze and deicing measures are easier. Multiple units can be designed in combination, and in winter, the fans can be combined for single operation or all fans can be stopped at the required water temperature and water volume.V3qCooling tower noise reduction treatment manufacturer

  (3) Construction, installation, and maintenance are relatively easy and low-cost. It is often used in air conditioning and industrial large, large and medium-sized cooling circulating water.V3qCooling tower noise reduction treatment manufacturer

  B, cross flow cooling tower

  (1) The water is in the filling material in the tower, the water flows from top to bottom, and the air flows horizontally from the outside of the tower to the inside of the tower, and the two flow directions are perpendicular to a cooling tower. Frequently used in residential areas with strict noise requirements, it is a cooling cycle tower that is more commonly used in the air conditioning industry. Advantages: energy saving, low water pressure, low wind resistance, low-speed motor is also equipped, no dripping noise and wind noise, easy maintenance of filling materials and water distribution system.V3qCooling tower noise reduction treatment manufacturer

  (2) Multiple foundations can be constructed and placed at will according to the shape of the building, and single or multiple cooling towers can be activated according to the required water temperature.V3qCooling tower noise reduction treatment manufacturer

  (3) It should be noted that: the frame should be 40% more heat exchange, and there should be more filling material volume, the filling material is easy to age, the water distribution hole is easy to block, the anti-icing is not good, and the moisture return is large.V3qCooling tower noise reduction treatment manufacturer

  (4) The advantage of the cross-flow tower is exactly the disadvantage of the counter-flow tower.V3qCooling tower noise reduction treatment manufacturer

  C, spray natural ventilation cooling tower without filler

  Use a unique spray nozzle to install at the air supply above the bottom of the cooling tower. There are two methods for spray automatic rotation without motor air supply and tower exhaust air. When the hot water is passed through the inner rotating fins of the nozzle, an inner swirling flow is generated to produce a fine mist and vaporized and sprayed out, so that the mist exists, and it is sprayed upwards and downwards, and there are two cooling aging effects. The atomization is uniform and has no hollow condition, the cooling effect remains stable, the power consumption is low, the water bleaching rate is 0.01%, no filler is needed, the project cost is low, and the service life is long. It conforms to the GB7190.1-1997 national industry standard. Application of regional metallurgy, food, chemical, high turbidity, high temperature, anti-corrosion cooling tower.V3qCooling tower noise reduction treatment manufacturer
