Product advantages and technical features

        In the open cooling tower circulation system, because the circulating liquid medium is in the air for a long time, pollutants in the air such as dust, debris, bacteria, and soluble solids can enter the cooling water system at any time, causing a large number of microorganisms to multiply, which is very easy for the human body and Harm to the environment, as well as causing pipe fouling and affecting heat transfer.z2kCooling tower noise reduction treatment manufacturer
        The closed cooling tower adopts an indirect contact cooling method. The circulating liquid medium flows in the coil, which prevents the cooling water from being polluted by the external environment. The heat of the cooling water in the pipe is transferred by the circulating water flow in the tower to evaporate the latent heat, and the evaporated water vapor is transferred from the air. The stream is brought out of the tower. Closed cooling towers are suitable for various cooling systems that require high circulating water quality, and are widely used in many industrial fields such as chemical, steel, food, automobile manufacturing, and central air conditioning.
        The practice of ultra-quiet closed cooling tower is to change the original fan diameter, expand the air outlet, increase the fan, reduce the fan speed, increase the air volume, and achieve noise reduction.

A、Working principle of closed cooling tower

        The circulating liquid medium that needs to be cooled flows in the coil, the circulating water in the sump is delivered to the water collection pipe by the spray pump, and sprayed to the heat exchange coil through the water distribution nozzle. The contact heat transfer and part of the spray water evaporate and dissipate heat to absorb The heat in the water in the coil is transferred to the air. The hot and humid air is discharged from the tower by the fan, and the rest of the spray water flows into the sump in the lower part of the tower, and then is delivered to the spray system by the spray water pump.

Low power consumption ratio, overall power consumption ratio ≤0.07kw/(m3/h), long-term operation can save energy and reduce operating costs.z2kCooling tower noise reduction treatment manufacturer
        Fan: The function of the fan is to introduce air into the tower to provide dry air with a high flow rate and a steady flow, which facilitates the latent heat exchange between the cooling water on the copper pipe and the air, thereby improving the cooling efficiency and ensuring the cooling effect. Axial-flow fans are generally used in mechanical ventilation towers. The axial-flow fans have large air volume and low wind pressure, and can be reversed for a short time, which is beneficial to prevent freezing during winter operation. The angle of the blades can be adjusted to change the air volume and pressure.z2kCooling tower noise reduction treatment manufacturer
D、 Heat exchange coil (phosphating and deoxidizing copper tube)z2kCooling tower noise reduction treatment manufacturer
        1、Use thermally conductive materials with high heat transfer coefficient
        The heat exchange coil is the core component of the closed cooling tower. The selection, design, and use of the heat exchange coil are directly related to the use effect of the closed cooling tower. Our company selects phosphorus deoxidized copper heat transfer tube according to the design and use for many years, and the pressure design is 1.6Mpa. Each set of coils needs to pass a 2.0MPA gas pressure test in the water before leaving the factory. It has better corrosion resistance and heat exchange efficiency than galvanized pipes, stainless steel pipes, and aluminum pipes. The high-efficiency coils designed and used have excellent Cooling capacity. The copper tube is hard in texture, not easy to corrode, and is resistant to high temperature and high pressure, and can be used in a variety of environments. Compared with this, the shortcomings of many other pipes are obvious. For example, the galvanized steel pipes used in the past are very easy to rust, and the water quality will become yellow and the water flow will become small if they are not used for a long time. Therefore, the use of copper pipes is suitable for cooling various fluids such as pure water, quenching fluid, hydraulic oil, and Freon.z2kCooling tower noise reduction treatment manufacturer

        ③.Avoid maintenance problems caused by fouling of heat exchange coils, especially suitable for "dry operation" in winter conditions.z2kCooling tower noise reduction treatment manufacturer
        2、With automatic drainage function
        After the closed tower is shut down in winter, if the circulating water in the coil cannot be drained cleanly, it is easy to cause the coil to freeze under low temperature in winter, which will reduce the service life of the coil. To solve this problem, our company is designing the coil When the pipe arrangement of each group of heat exchange coils presents a certain slope, the coil group is of inclined design, and the slope design is consistent with the direction of water flow to facilitate the discharge of water in the pipes. The water can be completely discharged automatically, extending the service life and Meet the antifreeze requirements of closed towers in winter operation.z2kCooling tower noise reduction treatment manufacturer

      The spray pump sprays a large amount of water on the copper pipe. Since the upper part is relatively close to the location of the fan, in order to prevent some water from being sucked out of the machine by the fan, the water collector is required to block the exhaust system to discharge the spray water and hot steam. Go; the arc-shaped PVC high-efficiency dehydrator is used to ensure high-efficiency ventilation, while the floating rate of the spray water is less than 0.001%, which can make the equipment part in the sensitive area of the floating water.z2kCooling tower noise reduction treatment manufacturer
