Everyone should be familiar with closed cooling towers. Then everyone knows what impacts the daily closed cooling towers will have when the drainage is not clean. Let's take a look at trlon air conditioners in detail.
The heat rejection capacity of the closed cooling tower is designed and selected according to the hot summer climate. In other seasons, especially in winter, the heat rejection capacity may be too large. When the closed cooling tower is in operation, even if the ambient temperature is higher than zero, the closed cooling tower may drop the water in the pipe to zero or even freeze. The closed cooling tower is to place the tubular heat exchanger (heat exchange coil) in the tower, and ensure the cooling effect through forced ventilation, heat exchange between spray water and circulating water. Its closed cycle characteristics can ensure that the water consumption is very small, the water quality is not polluted, and the efficient operation of the main equipment is extremely ensured, and the service life is extended.
In the tower body, the water collection trough, spray pipes, and sprinkler head parts shall be cleaned up in time to avoid the accumulation of scale and dirt and block the pipes. Check the packing part to check whether there is dirt on it. The dirt needs to be cleaned up in time to ensure a clean heat exchange environment. Clean the dirt on the outer surface of the fan blade, check the angle of the fan blade, the gap between the fan blade and the wind shell, and adjust it.
Check whether the floating ball of the copper ball valve in the sump of the closed cooling tower is damaged and working properly, check whether there is water leakage in the sump, tower foot, etc., if there is a leak, make up the glue in time, and check whether the terminal of the fully enclosed motor Intact, whether the motor rotates with a sensation or abnormal sound, whether the motor fixing screw is loose, check whether the closed cooling tower reducer rotates normally, if there is abnormal sound, immediately replace the reducer bearing to check whether the fan blades are evenly distributed for looseness.
For tube-fin heat exchange equipment such as closed cooling towers, in order to prevent the tube slices from freezing and cracking in the low-temperature climate, the circulating water in the tube slices should be drained during shutdown. But nowadays, cross-flow closed cooling towers generally have the problems of slow water discharge speed and unclean drain, which cause the tube slices to freeze and crack. Otherwise, because of the dirty drainage, even if there is no freezing and cracking, if the tube is partially frozen, water hammer may also cause the start-up The whole machine is faulty such as pipe burst, so the cross-flow closed cooling tower has frequent freezing and cracking faults in actual use.
A closed cooling tower is a tube heat exchanger placed in the tower, and the cooling effect is ensured by the heat exchange between circulating air, spray water and circulating water. Because it is a closed cycle, it can ensure that the water quality is not polluted It can effectively protect the efficient operation of the main equipment and increase the service life. When the outdoor temperature is low, the water spray system can be stopped to achieve water saving effects. In recent years, with the implementation of the national energy saving and emission reduction policy and the shortage of water resources , Closed cooling towers have been widely used in steel metallurgy, power electronics, mechanical processing, air conditioning and other industries.
According to the flow direction and wind direction, it can be divided into countercurrent closed cooling tower and cross flow closed cooling tower. According to the shell material, it can be divided into: galvanized steel plate closed cooling tower, aluminum zinc plate closed cooling tower, stainless steel closed cooling tower, glass fiber Reinforced plastic enclosed cooling tower, etc.
According to the material of the heat exchanger, it can be divided into copper tube closed cooling tower, stainless steel tube closed cooling tower, carbon steel tube closed cooling tower, titanium tube closed cooling tower, aluminum tube closed cooling tower, etc. According to the type of fan, it can be divided into closed type Ventilation cooling tower and closed closed cooling tower.
A closed cooling tower is actually a kind of evaporative cooling tower, which is a combination of a cooling tower and a wet cooling tower. This is a horizontal evaporative cooling tower. The process fluid flows through the pipe, and the air flows through the pipe. There is no contact between the two. Closed The cooling tower is a modification and development of the traditional cooling tower. The water in the bottom of the tower is pumped out by the circulating pump and transported to the outside of the pipe to be sprayed evenly. It is not in contact with the hot water of the process fluid or refrigerant and the air outside the pipe. It becomes a closed Of cooling towers to improve heat and mass transfer effects by spraying water
