FRP products have the advantages of simple construction, compact structure, good corrosion resistance, low cost, light weight and high strength. Since its inception, FRP products have quickly become cooling towers that replace wood, steel, reinforced concrete and other materials. As a result, FRP products have become one of the number one finalized products in the FRP industry.
The main function of glass fiber reinforced plastic products is to carry out a heat exchange between the cooling water carrying waste heat and the air in the tower, so that the waste heat is transferred to the air and dispersed into the atmosphere. According to the relative flow direction of water and air in the filler, FRP products can be divided into two types, counter-flow type and cross-flow type, with shapes such as round and square.
The waste heat generated during industrial production or refrigeration processes is generally conducted away with cooling water. The role of the cooling tower is to exchange the cooling water with the waste heat in the tower and the air, so that the waste heat is transferred to the air and dispersed into the atmosphere. For example: In a thermal power plant, the boiler heats water into high-temperature and high-pressure steam, which pushes the steam turbine to do work to make the generator generate electricity. The exhaust steam after the steam turbine does the work is discharged into the condenser, and it exchanges heat with the cooling water and condenses into water, which is then pumped Return to the boiler for recycling. In this process, the waste heat of exhaust steam is transferred to the cooling water, which raises the temperature of the water and entrains the waste heat of the cooling water. The heat is transferred to the air in the cooling tower and discharged into the atmosphere from the wind tube. Cooling tower application range: mainly used in air conditioning cooling systems, refrigeration series, injection molding, tanning, foaming, power generation, steam turbines, aluminum profile processing, air compressors, industrial water cooling and other fields. The most applications are air conditioning cooling, freezing, Plastic chemical industry.
Because of the need to save energy, natural ventilation cooling towers are often used for large cooling towers, which are composed of ventilating cylinders, herringbone columns, ring bases, water spraying devices and tower core materials.
The ventilation cylinders are mostly reinforced concrete hyperbolic rotating shells, which have good structural mechanics and fluid mechanics characteristics. The lower edge of the shell is supported on equidistant V-shaped or X-shaped inclined pillars to form the air inlet of the cooling tower. The load of the shell is transmitted to the foundation through the diagonal struts. The foundation is mostly made of a ring-shaped foundation with a slope to withstand part of the ring tension transmitted by the inclined pillar, or it can be made into a separate single foundation or pile foundation.
The throat of the ventilation tube has the smallest diameter. When the shell is calculated to be stable under pressure, the shell wall is the thinnest. From here, the diameter gradually increases to form the airflow outlet diffuser. There is a rigid ring at the top of the tower, and the throat is shaped like a hyperbola. Gradually enlarged, the shell wall of the lower section is thickened correspondingly, forming a lower ring beam with certain rigidity. The ventilating tube can also be made into a truncated cone shell or a combined cone shell, or a polygonal tower tube with a steel frame and a wooden shield or asbestos cement shield.
