Why is the closed cooling tower tall and big? Look at the structure inside.
1. Water drenching filler It is the main component of hot water cooling in the tower, called "gastrointestinal system". The hot water that needs to be cooled is splashed into water droplets or a water film is formed, which increases the contact area between water and air and prolongs the contact time, promotes the heat exchange between hot water and air, and cools the water.
1. Water drenching filler
It is the main component of hot water cooling in the tower, called "gastrointestinal system". The hot water that needs to be cooled is splashed into water droplets or a water film is formed, which increases the contact area between water and air and prolongs the contact time, promotes the heat exchange between hot water and air, and cools the water.
2. Water distribution system
The function of the water distribution system is to evenly distribute the hot water throughout the filling. Whether the hot water is evenly distributed has a great influence on the cooling effect. If the water distribution is not uniform, it will not only directly reduce the cooling effect of the water, but also cause some cooling water droplets to splash and float out of the tower, increasing the water loss.
3. Ventilation equipment
In the upper tower body air duct of the mechanical ventilation cooling tower, a fan driven by a motor is set (the blast type is located in the lower part), and the designed air flow (ie, air volume) is generated by the rotation of the fan to ensure sufficient air and water. Heat exchange to achieve cooling effect.
4. Air distribution device
The air distribution device refers to the air inlet, shutters and air deflector, etc., the purpose is to guide the air evenly distributed on the entire section of the cooling tower, so as not to cause uneven air in the tower and vortex, reflux, etc., to ensure uniform water and air contact.
The function of the ventilation tube is to create good aerodynamic conditions, reduce ventilation resistance, and send the hot and humid air discharged from the cooling tower into the sky to prevent or reduce the backflow of hot and humid air. The ventilation tube of the mechanical ventilation cooling tower is also referred to as the air tube, which is basically made of glass fiber reinforced plastic. The air cylinder of the air cylinder type natural ventilation cooling tower is large and high in diameter, which plays the role of ventilation and sending wet air to high altitude, and is made of reinforced concrete.
6. Water removal (collection) device
The water droplets carried in the humid air outside the tower will be discharged, and the water droplets will be separated from the air by the water collector in the tower, so as to reduce the loss of water escaping (drifting) and the impact on the surrounding environment.
7. Tower body
Refers to the outer shell of the cooling tower, mechanical ventilation cooling tower and wind tube natural ventilation cooling tower) the tower body is closed, its role is to support, enclosure and organize the appropriate airflow function.
8. Collected pool
It is set at the lower part of the cooling tower (for small and medium-sized towers, there is no water collection tank for chassis at the lower part) to collect the cooling water falling from the drenching filler of multiple towers. The collection pool has a certain volume and sometimes plays a role in regulating the amount of water.
9. Intake and outlet pipes
The water inlet pipe delivers hot water to the water distribution system of the cooling tower, and the valve is set on the water inlet pipe to adjust the water volume into the tower. The water outlet pipe (small and medium-sized tower is located under the chassis) sends the cooling water to the water equipment or pool. Large tower for the pool, no water outlet pipe. Generally refers to the water pump from the pool pumping water to the water equipment pipe. There are supplementary water pipes, sewage pipes, overflow pipes, vent pipes, etc. in the collection tank.
