Regarding the classification and working process of the cooling tower, you want to know!
Cooling tower classification
1. The cooling tower is divided into ventilation methods:
1 natural ventilation cooling tower;
2 mechanical ventilation cooling tower;
3 mixed ventilation cooling tower.
2. The cooling tower is divided according to the contact mode of water and air:
1 wet cooling tower;
2 dry cooling tower;
3 dry and wet cooling towers.
3. The cooling tower is divided according to the flow direction of hot water and air:
1 counterflow cooling tower;
2 cross flow (straight AC) type cooling tower.
4. Cooling towers are divided according to application areas:
1 industrial cooling tower;
2 air conditioning type cooling tower.
5. The cooling tower is divided according to the noise level:
1 ordinary cooling tower;
2 low noise cooling tower;
3 ultra-low noise cooling tower;
4 ultra-quiet cooling towers.
6. Other types of cooling towers for cooling towers, such as jet cooling towers, fanless cooling towers, etc.
Cooling tower working process
Take the working process of a circular counterflow cooling tower as an example:
The hot water is pumped from the main room through the water pump to the watering system of the cooling tower through the pipeline, the throat, the throat and the central throat. The water is evenly spread on the packing through the small holes in the water pipe. The dry low-value air enters the tower from the bottom into the wind net under the action of the fan. The hot water flows through the surface of the packing to form a water film and air for heat exchange. The high-humidity and high-value hot air is extracted from the top and cooled. Water is dripped into the bottom basin and flows into the main unit through the outlet pipe.
Under normal circumstances, the air entering the tower is the air that dries the low-humidity temperature. There is obviously a difference in concentration of water molecules and a difference in kinetic energy between the water and the air. When the fan is running, under the action of static pressure inside 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 is lowered, so that the temperature of the circulating water is lowered.
It can be seen from the above analysis that the evaporative cooling and the temperature of the air (generally the dry bulb temperature) are lower or higher than the water temperature, and as long as the water molecules can continuously evaporate into the air, the water temperature is lowered. However, the evaporation of water into the air does not continue indefinitely. When the air in contact with water is not saturated, the water molecules continuously evaporate into the air, but when the air on the contact surface of the water vapor reaches saturation, the water molecules cannot evaporate, but are in a state of dynamic balance. The amount of water molecules that evaporate is equal to the amount of water molecules that return from the air to the water, and the water temperature remains the same.
It can be seen that the drier the air in contact with water, the easier it is to evaporate and the lower the water temperature.
