Jiangsu Yunuo Cooling Technology introduces how to complete the waste heat recovery and utilization of cooling towers.
Choosing the correct orientation device for the cooling tower can fundamentally ensure that the cooling tower can exert its calibrated cooling capacity. Its main purpose is to place the cooling tower in a position where the fresh air can enter the unit freely and without obstacles, and ensure a certain degree of reduction of backflow. One step in achieving this is to consider the various factors that may affect the cooling tower installation. After mastering these materials, the installation position of the sewage cooling tower can be correctly selected. Under normal circumstances, the cooling tower of the factory will be installed on the roof or other building floors, and has a satisfactory bearing capacity. Because of the excellent ventilation, the cooling tower helps to effectively dissipate heat, but we need to pay attention that during the installation process, the distance between the cooling tower inlet and the building should be at least 1.5 times the outer diameter of the tower, which can To meet the requirements of the new wind vane, it does not need to be installed on a high wall without ventilation.
If you choose the installation location of the cooling tower, you should pay attention to whether there is soot or dust, and do not install it in this place to avoid being blocked by soot and dust. The working principle of the cooling tower is that the ventilated air is blown from the correct viewpoint to the dripping water. When the air passes through these water droplets, some of the water will be evaporated, because the heat used to evaporate the water droplets reduces the temperature of the water, and the remaining water will be cooled. The cooling effect of this method relies on the relative humidity and pressure of the air. When the water droplets come into contact with the air, on the one hand, there is no direct heat transfer between the air and the water, and on the other hand, there is a certain pressure difference between the surface of the water vapor and the air. Taking away is the heat transfer by transpiration, so as to achieve the purpose of cooling.
The cooling tower can exchange the cooling water carrying waste heat with the air inside the tower body, so that the waste heat is transferred to the air and dissipated into the atmosphere. Now the cooling tower is used more and more widely, and the cooling tower can complete the waste heat recovery to Take boiler hot water as an example. After the water is heated, it will form relatively high-temperature high-pressure steam to drive a steam turbine to generate electricity. The flue gas is then discharged into a condenser, and with the aid of a cooling tower, the flue gas is converted into water, which is then returned to the boiler for recovery.
In this process, the waste heat will transfer heat with the cooling water in the cooling tower, and the water temperature will increase. At the same time, the large amount of heat energy generated above can also be transferred to the air, so if other equipment is equipped, it may have a greater effect. The cooling tower can act through the heat conduction between the circulating cooling water and the cold and dry air, and only after the transpiration of the circulating cooling water can the latent heat of gasification be removed, so as to achieve the purpose of lowering the water temperature. That is to say, when the cooling tower is running, it needs a certain pressure cycle to complete.
