The type of closed cooling tower is an automatic rotary atomizing cooling tower. To a certain extent, the heat conduction between circulating cooling water and cold and dry air and the evaporation of circulating cooling water take away the latent heat of vaporization to reduce the water temperature. The circulating cooling water with a certain pressure enters the cooling tower through the water inlet pipe. Under the swirling jet of the atomizer, it is atomized into mist and sprayed to the top of the tower. The resulting reverse thrust drives the automatic rotating device to rotate, ensuring the entire tower The body is full of mist. The axial fan installed on the top of the tower rotates, and the surrounding cold and dry air is forcibly sucked into the cooling tower through the air inlet window to conduct mass and heat transfer with the circulating cooling water.
The atomized water jet sprayed from the atomizer has a fast flow rate, and has the effect of entrainment and entrainment, which causes a certain negative pressure around the atomizer, increases the amount of air drawn from the surrounding environment and the flow rate of the cooling tower, and at the same time drives the bottom The air flows upwards, so that the cold and dry air and the water mist are mixed and contacted more fully. The particles of the atomized water flow are further refined, and the diameter can be reduced to 0.01mm. After the air and water are fully mixed, the mist airflow is sprayed upwards to the installation On the water collector at the top of the tower, the water is intercepted and returned to the cooling tower in the form of a water curtain. The heat in the air and water is discharged out of the tower through the water collector. This is the working principle and process inside the cooling tower.
The circulating cooling water in the cooling tower has three processes of ascending, suspending and descending. At the same time, the cooling also has two processes of downstream cooling and countercurrent cooling, so the contact time with cold and dry air is longer and more sufficient, and more heat is taken away. At the same time, due to the elimination of the filler, the phenomenon of air resistance does not exist, which reduces the power of the motor that drives the fan to rotate, and achieves the effect of reducing operating costs and increasing the temperature difference between inlet and outlet water. In addition, the contact area between water and air after atomization far exceeds the contact area between water and air in a packed cooling tower.
Closed cross-flow cooling tower: It is more suitable for use in places with a wide temperature range, high noise requirements, and limited installation vertical space. It can also be used in parallel to form a cooling tower group with various water volumes.
Closed counterflow cooling tower: Because this product has a compact structure and a small model, it can be placed in the workshop, so it can be used for intermediate frequency power supply cooling, mechanical water jacket cooling, etc.; the heat exchange area in the unit space is larger, so it is more suitable for Low temperature (35-30"C) cooling project with small temperature difference, etc.
Closed mixed-flow cooling tower: Because the packing of this product is separated from the coil, it is more suitable for projects with higher cooling temperature (such as 70-80℃) or large cooling temperature difference (such as 60-35"C). The product cooling range can also be small, but the energy consumption is relatively high.
