The cooling tower is a comprehensive product integrating aerodynamics, thermodynamics, fluidics, chemistry, biochemistry, materials science, static and dynamic structural mechanics, and processing technology. Water quality is a multi-variable function, and cooling is a multi-factor, multi-variable and multi-effect synthesis process. With the continuous development of the cooling tower industry, more and more industries and enterprises have used the cooling tower, and many enterprises have entered the cooling tower industry and developed.

The working principle of a cooling tower is that the ventilated air is blown to the dripping water from the correct angle. When the air passes through these droplets, part of the water evaporates. Because the heat used to evaporate the droplets reduces the temperature of the water, the remaining water Was cooled. The cooling effect of this method depends on the relative humidity and pressure of the air. When water droplets come into contact with air, on the one hand, due to the direct heat transfer between air and air, and on the other hand, due to the pressure difference between the water vapor surface and air, evaporation occurs under the effect of pressure. The heat in the water is taken away, that is, the heat is evaporated, thereby achieving the purpose of cooling. The working process of the cooling tower: The working process of the circular counterflow cooling tower is taken as an example: hot water from the main room through the pump at a certain pressure through pipes, cross throats, curved throats, and central throats to circulate water to the cooling tower's watering system Inside, the water is evenly sprayed on the filler through the small holes in the water-spreading pipe; the dry low-threshold air enters the tower from the bottom into the wind net under the action of the fan, and the hot water flows through the surface of the filler to form a water film. Heat exchange with air, hot air with high humidity and high value is drawn from the top, cooling water drops into the basin, and flows into the host through the outlet pipe. However, the evaporation of water into the air does not continue endlessly. When the air in contact with water is not saturated, water molecules continuously evaporate into the air, but when the air on the water-gas contact surface reaches saturation, the water molecules cannot evaporate, but are in a state of dynamic equilibrium. The number of water molecules evaporated is equal to the number of water molecules returned from the air to the water, and the water temperature remains the same.
