Methods of noise modification and treatment for cooling tower

  Summer is coming, and the weather is getting hotter and hotter. While cooling, it also brings the noise problem. Then today the closed cooling tower manufacturer will take you to understand the causes of the noise formation of the central air conditioning cooling tower and the transformation and treatment methods.vLeCooling tower noise reduction treatment manufacturer

  How to deal with the noise of cooling towervLeCooling tower noise reduction treatment manufacturer

  1. Specific measures for noise reduction of fansvLeCooling tower noise reduction treatment manufacturer

  (1) improve the diameter of the wind wheel, reduce the rotation speed of the fan, reduce the speed in the circle, according to the characteristics of the cooling tower and the provisions of environmental protection and energy saving, improve the diameter of the wind wheel, reduce the export dynamic pressure, so as to achieve the provisions of environmental protection, energy saving and noise reduction. Reducing the speed in the circle is also an important way to reduce the noise of the fan.vLeCooling tower noise reduction treatment manufacturer

  (2) The broad leaf with a large arc connection, its shape is similar to the rectangle with an arc, suitable for matching low speed drive, to achieve high efficiency and noise reduction processing provisions.vLeCooling tower noise reduction treatment manufacturer

  (3) The airfoil blade is less than the same thin and thick plate blade, especially the gale blade and at high speed, it has a higher lift coefficient and a large Angle of attack, which is beneficial to reduce the periodic oscillation and wake vortex, can achieve a large amount of noise reduction processing, and has good steam dynamic characteristics.vLeCooling tower noise reduction treatment manufacturer

  (4) The uniform flow contraction line is adopted to achieve the maximum equilibrium velocity field of the air flow, minimize the eddy current at the inlet of the fan, and ensure the conventional operation conditions of the axial flow fan.vLeCooling tower noise reduction treatment manufacturer

  (5) The gap between the outer edge of the blade and the shell should be constant, otherwise unbalanced oscillation will occur and periodic pulsating noise will occur. Therefore, the radial runout of the outer edge should be controlled.vLeCooling tower noise reduction treatment manufacturer

  The end face of the wind blade should be in the same level, otherwise it will form the cause of turbulent noise.vLeCooling tower noise reduction treatment manufacturer

  Enhance the processing and assembly accuracy of the entire equipment accessories, but also reduce the noise of the fan.vLeCooling tower noise reduction treatment manufacturer

  (8) To enhance the rotor balance accuracy, static calibration first, then dynamic balance correction, in order to reduce vibration and the vibration noise caused by the blade oscillation.vLeCooling tower noise reduction treatment manufacturer

  Two, the concrete measures to reduce the noise of water pouringvLeCooling tower noise reduction treatment manufacturer

  (1) improve packing thickness, improve packing layout;vLeCooling tower noise reduction treatment manufacturer

  (2) between the packing and the water tray hanging "snowflake" (because of its appearance such as snowflake and the name is the origin of high pressure polyethylene diameter horizontal pressure molding), can reduce the difference in falling into the water, so that the water droplets are further refined, reduce the noise of pouring water.vLeCooling tower noise reduction treatment manufacturer

  (3) by the surface of the pavement with polyurethane porous structure foam plastic. It is a kind of professional cooling tower noise reduction with a new environmental protection material, it not only has the general flexibility of foam plastic, and porous structure water permeability, can reduce the collision noise into the water.vLeCooling tower noise reduction treatment manufacturer

  (4) The air inlet is equipped with a parabolic shape radiating sound baffle, so that the air supply is not affected, and the noise falling into the water can not immediately spread outward.vLeCooling tower noise reduction treatment manufacturer

  Three, set the sound barriervLeCooling tower noise reduction treatment manufacturer

  In the cooling tower noise control project, the sound barrier is a common concrete measure to reduce the noise. But using a sound barrier around a cooling tower presents a series of challenges. Here are three things to keep in mind:vLeCooling tower noise reduction treatment manufacturer

  (1) In general, improving the sound barrier will affect the conventional air supply of cooling towers and the actual effect of cooling, which depends on whether the cooling tower used originally is set aside a rich volume, or it should be used with caution.vLeCooling tower noise reduction treatment manufacturer

  (2) cooling tower sound barrier in general, only one edge can be set, and only L-shaped layout can be set at most. If the noise affects a wide range of residents, the actual effect of setting the barrier is not ideal.vLeCooling tower noise reduction treatment manufacturer

  The high and wide area of the cooling tower sound barrier is generally very large, and most of the assembly is in a high place, see the wind pressure, the construction should consider whether the original building is strong, there is no assembly location.vLeCooling tower noise reduction treatment manufacturer

  Four, add silencervLeCooling tower noise reduction treatment manufacturer

  Adding the muffler into the exhaust pipe will also affect the actual effect of natural ventilation, so the muffler in addition to the muffler volume provisions, natural ventilation resistance to be small.vLeCooling tower noise reduction treatment manufacturer

  The above is the method of reducing the noise of the cooling tower. If you have the convenient problem of the noise of the cooling tower, please call to consult!vLeCooling tower noise reduction treatment manufacturer
