Basic principle of closed cooling tower water circulation system (text and diagram description)

Release time：

Basic principle of closed cooling tower water circulation system:
Closed cooling tower is to use the working pressure caused by centrifugal water pump or other working pressure equipment to make the water with high temperature from cooler, absorber or process technology, that is, cooling circulating water, be transferred to the cooling fan coil of the closed cooling tower. The cooling circulating water enters the closed cooling tower, and the heat exchange is carried out according to the fitness exercise in the closed cooling tower and its contact with the wind liquid, The intelligent return water after entering the closed cooling tower generates small raindrop particles that spray vertically downward at high speed for fitness according to the working pressure swirl nozzle equipment installed at the top of the tower and the upper end of the air duct, completing the daily task of expanding the area of water droplets.
The water droplet will continue to encounter the rising air during the whole process of lowering, which slows down the rate of water particle reduction, thus increasing the heat exchanger time. The calorific value of the liquid is first sent to the inner cavity of the air conditioner copper tube, then sent to the surface of the air conditioner copper tube from the inner cavity, and then sent to the self spraying shrink water from the surface. The shrink water and gas generate saturated cold and wet steam. The calorific value is discharged into the air by the centrifugal fan, and part of the water droplets are purchased by the water collector and filter to reduce the damage caused by the self spraying.

When the self spraying water is reduced to a certain amount, the float switch will automatically replenish water and moisturize, and the cycle will be continuous. In addition, because the closed cooling tower removes the open filler equipment and becomes an empty tower, the friction resistance of the tower body is reduced. With the effect of the centrifugal fan, the wind force and exhaust air volume are expanded, the water air ratio is increased, and the actual effect of temperature reduction is improved.
Water collecting reservoir: collect the water after passing through the heat transfer fan coil, and also use it to store and adjust the water flow, so as to achieve the goal of saving water resources in the circulating system.
Louver curtain: the wind shall be evenly distributed to the tower body to ensure no external splash.
Maintenance door: convenient maintenance and mid and late maintenance.
Centrifugal fan: the centrifugal fan is used to introduce the gas into the tower body, so as to create the gas with high water flow and stable total flow, thereby improving the refrigeration efficiency and ensuring the actual refrigeration effect.
Water filter: High efficiency intensive water filter is selected to reduce the circulating damage of cooling water.
Automatic spraying system: make the high-temperature cooling circulating water entering the tower expand the contact area with gas as much as possible, improve the exchange of boiled water between steam, send the heat of high-temperature cooling water to gas, thereby reducing the temperature of cooling circulating water, and achieve the goal of repeated use of water source.
Cooler: cooler is the key component of closed cooling tower, and its effective structure specification and effective layout method will immediately endanger the heat exchange efficiency of all closed cooling towers, and will also endanger the refrigeration capacity of all closed cooling towers for cooling circulating water. The skewed layout method of cooler is beneficial to drain the water in the cooler in winter to avoid the freezing of air conditioning copper pipe
