[FRP cooling tower] -Application scope of FRP cooling tower-

The waste heat generated during industrial consumption or refrigeration process is usually conducted by cooling water. The role of the cooling tower is to stop the heat exchange between the cooling water with waste heat and air in the tower, so that the waste heat is transmitted to the air and dispersed into the atmosphere. For example, in a thermal power plant, the boiler heats water into low-temperature and high-pressure steam, advances the turbine to do work to generate electricity from the generator, and the exhaust steam after the work of the turbine is discharged into the condenser. Back to the boiler cycle. In this process, the waste heat of the exhausted steam is transferred to the cooling water, which reduces the temperature of the water. The cooling water with the waste heat is transferred to the air in the cooling tower and discharged into the atmosphere from the wind tube. Application scope of cooling tower: It is mainly used in air-conditioning cooling fragmentation, freezing series, injection molding, tanning, foaming, power generation, steam turbine, aluminum profile processing, air compressor, industrial water cooling, etc., the most widely used are air-conditioning cooling, freezing , Plastic chemical industry. In order to save power, large-scale cooling towers mostly use natural ventilation cooling towers, which are composed of ventilators, herringbone columns, ring foundations, water installation and tower core data. The ventilators are mostly reinforced concrete hyperbolic rotating shells, which have good structural mechanics and flow mechanical properties. The lower edge of the shell is supported on V-shaped or X-shaped inclined pillars at equal intervals to form the air inlet of the cooling tower. The load of the shell is transmitted to the root through the inclined support. The root base is mostly made into a circular root base with a slope to accept the local ring tension transmitted by the inclined pillar, and it can also be made into a single base or a pile base for differentiation. The diameter of the throat of the ventilator is the smallest. When the shell is firmly determined to be under pressure, the shell wall is the thinnest. From this, the diameter increases gradually to form a dispersed section of the air outlet. A rigid ring is provided at the top of the tower. Gradually expanding, the lower section of the shell wall is also thickened accordingly, forming a lower ring beam with a certain stiffness. The ventilation tube can also be made into a truncated cone shell or a combined cone shell, or a polygonal tower tube covered with a wooden frame or a asbestos cement cover with a steel frame. In a 146-meter-high dry-type cooling tower in the nuclear power plant in Schmeihausen, Germany adopted a tower with a cable structure, which was covered with aluminum shields and aluminum shields, which had better seismic and wind resistance.
