New Ji Cooling tower manufacturers

Cooling tower is the use of water and air flow contact after the cold and heat exchange to produce steam, steam evaporation to take away heat to achieve evaporation and heat dissipation, transmission heat and radiation heat transfer and other principles to disperse the waste heat produced in industrial or refrigeration air conditioning to reduce the water temperature evaporation heat dissipation device, in

The basic principle is: the drying (low enthalpy value) of the air through the fan's twitching, from the inlet wind network into the cooling tower, saturated steam division pressure high temperature water molecules to low pressure air flow, hot and humid (high enthalpy value) of the water self-sowing water system sprinkled into the tower. When water droplets and air contact, on the one hand due to air and non-direct heat transfer, on the other hand, due to the water vapor surface and air between the pressure difference, under the action of pressure to produce evaporation phenomenon, brought to the current for the evaporation of latent heat, the heat in the water is evaporated heat transfer, so as to achieve the goal of cooling.Cooling tower ManufacturersThe working process of the cooling tower: The working process of the circular countercurrent cooling tower is an example: the hot water Autonomous machine room through the pump with a certain pressure through the pipe, transverse throat, curvature throat, the central throat will be circulating water pressure to the cooling tower of the water sowing system, through the small hole on the pipe surface will be evenly sprinkled on the filler ; dry low Han value air under the action of the fan from the bottom into the wind net into the tower, hot water flowing through the filler surface to form a water film and air for heat exchange, high humidity Gao value of the hot air from the top, cooling water dripping into the bottom basin, through the outlet pipe into the host. In general, the air entering the tower, is dry low wet ball temperature of the air, water and air between the concentration of water molecules and the difference in kinetic energy pressure, when the wind is running, under the action of static pressure in the tower, water molecules continue to evaporate into the air, become steam molecules, the average kinetic energy of the remaining water molecules will be reduced, This causes the temperature of the circulating water to drop. From the above analysis, it can be seen that evaporation cooling is not related to the temperature of the air (usually the dry ball temperature) below or above the water temperature, as long as the water molecules can continue to evaporate into the air, the temperature will be reduced. However, the evaporation of water into the air does not go on endlessly. When the air in contact with water is unsaturated, the water molecules continue to evaporate into the air, but when the air on the contact surface of the water gas reaches saturation, the aqueous molecule evaporates and is in a state of dynamic equilibrium. The amount of water molecules evaporated is equal to the number of water molecules returned to the water from the air, and the water temperature remains the same. From this, it can be seen that the drier the air in contact with water, the easier it is to evaporate, and the easier it is to reduce the water temperature.
Scope of application of cooling tower
Waste heat generated during industrial production or refrigeration processes is generally used to guide away with cooling water. The function of the cooling tower is to heat the cooling water in the tower with air, so that the waste heat is transmitted to the air and dispersed into the atmosphere. For example: In thermal power plants, boilers heat water into high-temperature high-pressure steam, promote steam turbines to do work so that generators generate electricity, through the steam turbine after the work of the waste steam discharged into the condenser, and cooling water for heat exchange condensation into water, and then use the pump back to the boiler recycling. In this process, the waste heat of the steam is passed to the cooling water, which increases the temperature of the gas, carries the heat water of the waste heat to the air in the cooling tower, and is discharged from the windpipe into the atmospheric environment.Cooling tower ManufacturersProduction of cooling tower application range: Mainly used in air conditioning cooling system, refrigeration series, injection molding, tanning, foaming, power generation, steam turbine, aluminum profile processing, air compressor, industrial water cooling and other fields, the most widely used for air conditioning cooling, refrigeration, plastic chemical industry.
