Dry-wet combined closed cooling tower is an efficient and environmentally friendly cooling equipment that combines the advantages of dry and wet cooling towers, and is widely used in electric power, chemical, metallurgical and other industrial fields.
Dry-wet combined closed cooling tower is an efficient and environmentally friendly cooling equipment that combines the advantages of dry and wet cooling towers, and is widely used in electric power, chemical, metallurgical and other industrial fields.
Its working principle is that the circulating water first passes through the finned tube and then flows into the coil, the outer wall of the coil is wrapped by the spray water, and the heat of the circulating water is transferred to the spray water through the coil wall. At the same time, the spray water and the inlet air flow in the opposite direction for heat exchange, the formation of saturated hot and humid air, and then discharged through the fan. When the external spray water stops spraying, the cooling tower can dissipate heat through its own fin structure to realize the function of water saving and fog elimination.
The advantages of this kind of cooling tower include: high cooling efficiency, saving water resources, reducing operating costs, solving the problem of ineffective air cooling in summer and high water consumption of evaporative cooling, and balancing the contradiction between water saving and efficiency. In addition, it can also perform dry operation cooling at higher ambient temperature, with high water saving rate, intelligent control and economic operation.
In the application scenario, the dry-wet combined closed cooling tower is especially suitable for water-scarce and arid areas, such as the northwest region, to reduce water consumption and reduce branch costs. At the same time, in areas with abundant power, such as wind power, hydropower, tidal power and nuclear power, it is also suitable to use this kind of cooling tower, because the air volume required for dry operation is large, and the power of the fan motor is relatively large, which can make full use of the electric energy in these areas.
In general, wet and dry combined closed cooling tower is a set of aerodynamics, thermodynamics, fluid science, materials science, static and dynamic structural mechanics, intelligent control and other disciplines as one of the integrated system technology, has a wide range of application prospects.
