WORKING PRINCIPLE
-
A cooling tower is designed to remove heat from a building or facility by spraying water down through the tower to exchange heat into the inside of the building. Air comes in from the sides of the tower and passes through the falling water.
-
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature.
-
Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of dry cooling towers, rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators.
-
Tower body temperature weight: reduce the design requirements for the foundation and installation costs.
-
The cooling water volume of the tower can be adjusted: for a given type of cold water tower, with working water pressure change (that is, flow change) in and out of the water temperature difference is generally unchanged, so you can increase the water supply pressure method to improve the cooling water volume of the tower (within the scope of the spray device), but also can change the nozzle aperture method to adjust the tower water volume and temperature drop.
-
No plugging, no maintenance, stable and reliable operation. A series of phenomena that affect the performance of the tower and process system equipment such as the plugging of the packing column due to the impurities in the circulating water, the aging of the packing, the deformation, the brittle-cracking, the plugging and flushing of the sprinkler head, the plugging of the packing brittle-chip in the pipeline, the pump and the heat exchanger are completely eliminated. It completely eliminates the trouble of frequent cleaning, replacement of filler and spray nozzle
-
Small floating water rate: the spray device is evenly distributed in the tower, and the outlet area is about twice as large as that of the traditional power tower, so the wind speed is small. At the same time, the top of the tower is installed with excellent performance of the water collection device, which minimizes the amount of floating water, and eliminates a lot of water refill.
-
Good cooling effect: the hot water in the tower exchanges heat with the incoming air under the condition of mist. Due to the small wind resistance in the tower and the reasonable design of air duct and wind blade, the ratio of air to water is improved.
-
Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers.
