Design features of 300 ton closed cooling tower
In order to adapt to the harsh environment, the shell of the 300-ton closed cooling tower adopts imported galvanized sheet, which is one of the galvanized sheets with strong corrosion resistance, strong heat resistance, strong heat resistance, and beautiful appearance. The shell material of the 300-ton closed cooling tower is stainless steel, glass steel, galvanized zinc, etc. Each material has excellent corrosion resistance and stability, customers can choose according to their needs.
Surface cooler (coil): a total of 5 groups, made of stainless steel pipes with a diameter of 19mm and a wall thickness of 0.8 mm. The stainless steel heat exchange coils have high heat exchange efficiency, good heat transfer performance, and are resistant to rust, corrosion and resistance. Grinding, acid and alkali resistance, etc.
includes fan blades, air ducts, and protective covers; the main function is to discharge the saturated hot and humid air in the cooling tower and introduce fresh air. The protective cover of the 300-ton closed cooling tower is made of stainless steel mesh, which is beautiful and durable. The blades are made of aluminum alloy, and the air duct is induced wind, with low noise and high rotation efficiency.
As the 300-ton closed cooling tower needs to bear relatively large work load during operation, its motor should be equipped with a frequency converter, which not only has higher energy-saving advantages, but is also very beneficial to the motor, which greatly improves the safety of production.
The spray pump adopts a stable, efficient and energy-saving new type of Hailong pipeline pump, adopts a hydraulic model that has absorbed foreign experience, and cooperates with a low-speed motor. Without affecting the cooling efficiency, the noise generated during operation is greatly reduced, and the wearing parts are doubled. Service life.
Air intake grille: waterproof, splash-proof, dust-proof, direct sunlight, large air inlet, small wind resistance, reduce fan energy consumption, prevent spray water from splashing, and prevent sunlight from entering the water tank of the 300-ton closed cooling tower. Effectively ensure the water quality and use temperature of the spray water, and effectively prevent the growth of dust and algae;
Research shows that the loss of floating water depends not only on the depth and number of revolutions of the eliminator, but also on the design water volume and air volume. The floating rate of the standard 300-ton closed cooling tower reaches 0.001%. If you want to reach a lower goal, you can explain it when you buy again so that we can make appropriate changes.
In order to fix the pipe-type sprinkler system, a new type of sprinkler in the industry is used. The amount of water required for sprinkling is low, and there is no hollow phenomenon, that is, a circular surface is formed on the plane instead of a ring, which is conducive to uniform water distribution. Improve thermal efficiency. , The installation and disassembly of the nozzle is very convenient, no tools are needed.
The advantages of a 300t closed cooling tower.
1. There is no need to dig a reservoir, the area is small, and the operation, installation and maintenance are easy.
2. Closed circulation cooling can solve the corrosion and damage of equipment caused by scaling, and it is environmentally friendly and stable.
3. Effectively solve the problem of extended drainage time and waste of electricity bills due to scaling of electric furnaces and other equipment.
4. Solve the problem of pipe blockage caused by debris entering.
5. Automatic digital display temperature control, water-saving and energy-saving, simple operation.
6, 300-ton closed cooling tower is fully enclosed and internally circulated for cooling, so no external impurities enter the cooling pipeline system, effectively preventing pipeline blockage and other phenomena, ensuring the service life of the equipment.
7. It adopts soft water cooling, which is characterized in that it is not easy to form scale under high temperature.
Precautions for the use of a 300-ton closed cooling tower.
1. Open the valve on the outlet pipe of the cooling tower and adjust the outlet water to the recommended ratio.
2. Continue to run the pump for about 15 minutes, and then it is recommended to empty and flush the entire water system before refilling.
3. Before running the circulating water pump and cooling tower fan, it is recommended to use a sodium hypochlorite treatment system or a fungicide for biological sterilization.
4. Hot and humid air recirculation, also known as hot and humid air return, refers to the moist air discharged from the air duct at the top of the 300-ton closed cooling tower, part of which is sucked into the tower, increasing the enthalpy and heat of the air entering the cooling tower, thereby reducing The cooling effect of the cooling tower itself. Therefore, the influence of hot and humid air returning from the cooling tower should be calculated in advance to accurately grasp the environmental parameters entering the cooling tower.
5. Practice has proved that the recirculation of hot and humid air not only exists in the operation of a 300-ton closed cooling tower, but is sometimes violent. The resulting wet bulb temperature is 0.5~1.2 higher, especially in the downwind direction of the cooling tower. The scope and extent of its influence are related to the length of the tower's single row layout, the dominant wind direction, the wind speed and the height of the wind tunnel.
6. The measuring point of the dry and wet bulb temperature should be located about 1.6 meters on the windward side of the tower, and the distance should be no less than 17 meters or more than 34 meters. The average value should be measured at three points within the range of the airflow.
Reflow will not only adversely affect the 300-ton closed cooling tower itself, but also cause the hot and humid air discharged from one or a series of cooling towers to enter other towers, causing mutual interference and reducing the actual cooling effect of the cooling tower.
