Products Description
Dry and wet combined closed cooling tower adopts high-efficiency cooling technology, high temperature water enters into the dry section of finned tube first, and the Dry and wet combined closed cooling tower achieves preliminary cooling through air convection;
When the water temperature is close to the wet bulb temperature, the spraying system of the Dry and wet When the water temperature approaches the wet bulb temperature, the spray system of the Dry and wet combined closed cooling tower is activated, the water film evaporates on the surface of the packing to enhance heat dissipation, and the unevaporated water droplets in the Dry and wet combined closed cooling tower are recovered; the humid hot air of the Dry and wet combined closed cooling tower continues to move upward with the finned tube dry section. The hot and humid air of Dry and wet combined closed cooling tower continues to go upward and contact with the finned tube for the second time, and through evaporation, the cooling effect of Dry and wet combined closed cooling tower further reduces the temperature of the tube wall, forming the "indirect-direct" composite cooling cycle.
Dry and wet combined closed cooling tower system Dry and wet combined closed cooling tower system through intelligent control of the spray volume and air volume, in low temperature environment can be completely dry operation, water saving rate of 85% or more, breakthrough in the traditional cooling tower is limited by the wet bulb temperature limitations, Dry and wet combined closed cooling tower through the integration of dry and wet two sets of system advantages, so that Dry and wet combined closed cooling tower in water saving and high efficiency of dissipation of water. By combining the advantages of both wet and dry systems, the Dry and wet combined closed cooling tower strikes a balance between water saving and efficient heat dissipation, making it an ideal choice for resource-saving industrial cooling. Therefore, the Dry and wet combined closed cooling tower is particularly suitable for water-scarce areas in northern China or for sustainable development projects in the context of global climate change.
