Description of the main structural characteristics of the closed cooling tower

Jiangsu Yunuo Cooling Technology Co., Ltd. will introduce to you the description of the main structural characteristics of the closed cooling tower The closed cooling tower produced by the Cooling System Equipment Management Co., Ltd. is made of T2 deacidified copper tubes of China's international social standard, all of which are bare copper round tubes without fins to ensure its cooling effect. The closed cooling tower places the tubular heat exchanger in the tower, and ensures the cooling effect through the heat exchange of circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, well protect the efficient operation of the main equipment, and improve the service life. When the outside temperature is low, the sprinkler system can be stopped to save water. An enclosed cooling tower is derived from an evaporative cooler and is actually a heat exchanger that combines the performance of a water-cooled cooler and a conventional cooling tower. It is also a heat exchanger between a water cooler and an air cooler, so some manufacturers call it an "evaporative air cooler". In the closed cooling tower, the tubular heat exchanger is placed in the tower, and the cooling effect is ensured through the heat exchange of circulating air, spray water and circulating water. The equipment has strong anti-corrosion ability, small coefficient of thermal expansion and contraction, high heat transfer technology performance, high temperature working environment, will not be softened by organic matter, will not be penetrated by other harmful gases or liquids, can kill bacteria, and has a long service life . The main development of the closed cooling tower has different characteristics of the following data structures: ①The heart part of the closed cooling tower (deacidified copper tube cooling tower) The cooling equipment adopts the international standard t2 deacidified copper tube, and the fully bare copper tube has no fins to ensure the cooling effect. Strong corrosion resistance, small coefficient of thermal expansion and contraction, good heat transfer performance, high temperature resistance, anti-corrosion, will not be softened by organic matter, will not be penetrated by harmful gases or liquids, can be sterilized, and has a long service life. The new international coil design adopts a serpentine shape to ensure the inclination angle, so that the medium water in the cooler can be completely discharged when not in use, which avoids freezing in winter for northern customers and prolongs the service life of the cooler. ②High strength design The wind pressure resistance of the cooling tower body reaches 150Kgf/m2, and it can bear the load of the 12th grade prevention typhoon (wind speed influence is greater than 240 km/h), and the basic seismic intensity requirement reaches VIII degree (eighth grade). ③ Easy maintenance and safety (1) The tower body is provided with a flexible access door, and the tower body is provided with a spacious and safe passageway. (2) Hot-dip galvanized steel ladders are installed on the outer surface of the tower to facilitate the management, maintenance and overhaul of the fan and the upper part of the cooling tower structure. The above is the relevant content introduced to you by Jiangsu Yunuo Cooling Technology Co., Ltd.

How should cooling tower fill be selected?

As the primary center of circulating water heat dissipation in industrial production, cooling towers affect the cost and power of industrial production in my country. Improper use of cooling towers in industrial production will result in untimely heat dissipation of equipment, stagnation of production, and danger of excessively high water temperature. The cooling tower packing is the primary factor to promote the water and heat cycle, therefore, it is necessary to choose high-quality cooling tower packing.

Techniques for the selection of cooling coil materials for closed cooling towers

First look at thermal resistance. In theory, the larger the thermal conductivity of the metal material, the smaller the thermal resistance, and the smaller the thermal resistance, the faster the heat transfer between the cooling liquid and the cooling water. Therefore, when choosing a cooling coil, be sure to choose a metal material with a large thermal conductivity. Now aluminum alloy, steel pipe and galvanized steel pipe are more commonly used cooling coil materials for closed cooling towers.

A brief introduction to the performance of the closed cooling tower

The performance characteristics of the closed cooling tower, the closed cooling tower is to place the tubular heat exchanger in the tower, and ensure the cooling effect through the heat exchange between the circulating air, the spray water and the circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted, and can effectively maintain the efficient operation of the main equipment and improve the service life.

How Industrial Cooling Towers Work

The working process of the cooling tower: the working process of the circular counter-flow cooling tower is an example: the hot water from the main engine room passes through the water pump through the pipeline, the horizontal throat, the curved throat and the central throat with a certain pressure to press the circulating water to the water spreading system of the cooling tower. Inside, the water is evenly spread on the filler through the small holes on the water-spreading pipe; the dry low-H value air enters the tower from the bottom air net under the action of the fan, and the hot water flows through the surface of the filler to form a water film It exchanges heat with the air, and the hot air with high humidity and high han value is extracted from the top, and the cooling water drops into the bottom basin and flows into the host through the water outlet pipe. Under normal circumstances, the air entering the tower is dry air with low wet bulb temperature. There is obviously a difference in concentration of water molecules and a difference in kinetic energy pressure between water and air. When the fan is running, under the action of static pressure in the tower, The water molecules continuously evaporate into the air and become water vapor molecules, and the average kinetic energy of the remaining water molecules will decrease, thereby reducing the temperature of the circulating water. It can be seen from the above analysis that evaporative cooling has nothing to do with the temperature of the air (usually the dry bulb temperature) being lower or higher than the water temperature. As long as the water molecules can continuously evaporate into the air, the water temperature will decrease. However, the evaporation of water into the air does not go on endlessly. When the air in contact with the water is not saturated, the water molecules continuously evaporate into the air, but when the air on the water-air contact surface is saturated, the water molecules cannot evaporate, but are in a state of dynamic equilibrium. The number 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. It can be seen from this that the drier the air in contact with the water, the easier the evaporation will proceed, and the easier the water temperature will be lowered.
