US and Japan to bring you a comprehensive understanding of the cooling tower
Cooling tower structure chart With the development of industrial production and the continuous improvement of people's living standards, it is urgent to control water environment pollution and rationally develop and utilize water resources. To this end, many units generally use the FRP cooling tower as an ideal equipment for high efficiency and energy saving, implement internal closed loops of water, improve the recycling rate, effectively reduce costs, and at the same time, make people adjust the temperature, humidity and cleanliness of the surrounding environment. The desire to influence noise has turned into reality. FRP cooling tower is corrosion resistant, high strength, light weight, small size, small footprint, beautiful and durable, and convenient for transportation, installation and maintenance. Therefore, it is widely used in various sectors of the national economy, and is particularly suitable for cooling water circulation systems such as air conditioning, refrigeration, air compressor stations, heating furnaces, and condensation processes. Round counterflow FRP cooling tower circular counterflow FRP cooling tower adopts counterflow gas heat exchange technology, the packing adopts high quality modified polychlorinated wave plate to diffuse the water spray area; through the water distribution method, the water distribution is uniform , enhance the cooling effect.
Water as a circulating coolant, a device that absorbs heat from a system and discharges it into the atmosphere to lower the temperature of the water; the cold uses the contact between water and air to exchange heat and heat to generate steam, which volatilizes heat to evaporate and dissipate heat. The principle of flow heat transfer and radiation heat transfer to dissipate the waste heat generated in the industrial or refrigeration air conditioner to reduce the water temperature evaporative heat sink to ensure the normal operation of the system, the device is generally barrel-shaped, hence the name of the cooling tower.
The working process of the FRP cooling tower: the working process of the circular counterflow cooling tower is as an example: the hot water from the main room passes through the water pump at a certain pressure, and the circulating water is pressurized to the cooling tower by the pipeline, the throat, the throat and the central throat. In the system, the water is evenly spread on the packing through the small holes in the water pipe; the dry low-value air enters the tower from the bottom into the wind net under the action of the fan, and the water forms water when flowing through the surface of the packing. The membrane exchanges heat with the air, and the hot air with high humidity and high enthalpy is extracted from the top, and the water is dripped into the bottom basin and flows into the host through the outlet pipe. Under normal circumstances, the air entering the tower is the air that dries the low-humidity temperature. There is obviously a difference in concentration of water molecules and a difference in kinetic energy between the water and the air. When the fan is running, under the action of static pressure in the tower, Water molecules continuously evaporate into the air, becoming water vapor molecules, and the average kinetic energy of the remaining water molecules is reduced, thereby lowering the temperature of the circulating water.
