　　Literally speaking, a cooling tower is a type of tower with cooling function, mainly using water as a circulating coolant, absorbing heat from the system and discharging it into the atmosphere to reduce water temperature. Its cooling is an evaporative heat dissipation device that utilizes the heat exchange between water and air flow to generate steam, which evaporates and carries away heat, achieving evaporative heat dissipation. The principles of convective and radiative heat transfer disperse the waste heat generated by industrial or refrigeration air conditioning, reducing water temperature. Nowadays, it is widely used, but there is white smoke during use, which makes many people wonder why white smoke is emitted. Today, the editor will talk to you about the reasons for white smoke during the use of cooling towers. Let's take a look!mteCooling tower noise reduction treatment manufacturer

　　Reasons for white smoke from cooling towers:mteCooling tower noise reduction treatment manufacturer

　　1. The enclosed cooling tower we see always emits white smoke, not smoke, but hot air. Cooling towers transfer waste heat from industrial production processes to the atmosphere through heat exchange with air. Due to the direct contact between industrial circulating cooling water in wet cooling towers and air, some of the hot water evaporates and carries latent heat into the air. The air temperature rises and the humidity increases, reaching 90% to 100%.mteCooling tower noise reduction treatment manufacturer

　　2. Furthermore, why does the air passing through the cooling tower exhibit a similar white smoke phenomenon at the tower outlet? This is related to the properties of air. Air is composed of dry air and water vapor. The constant components of dry air are nitrogen, oxygen, and rare gases. The reason why these components remain almost unchanged is the result of various natural changes compensating for each other. However, the amount of water vapor in the air can vary greatly, and due to differences in water vapor content, the air and its characteristics can also change. There is an upper limit to the amount of water vapor in the air. When the content reaches the upper limit, the air cannot accommodate any more water vapor. At this point, the air is saturated.mteCooling tower noise reduction treatment manufacturer

　　3. The higher the water vapor content in the air, the greater the temperature. The content of water vapor in the air is expressed by relative humidity, which means that at a certain temperature, the relative humidity of saturated air is 100% compared to the content of water vapor in saturated air. When the temperature of saturated air decreases, the amount of water vapor that the air can hold decreases, and some of the water vapor becomes liquid. Liquid water exists in extremely small particles, resembling white smoke. Mist in nature is also formed in this way.mteCooling tower noise reduction treatment manufacturer

　　4. The humid and hot air at the outlet of the closed cooling tower is saturated or close to saturation. After the cooling tower mixes with the surrounding low-temperature air, some of the water vapor in the humid and hot air becomes liquid, forming white smoke.mteCooling tower noise reduction treatment manufacturer

　　The above are all the reasons for the white smoke emitted during the use of cooling towers. From the above content, it can be seen that the appearance of white smoke is not true white smoke, but rather the illusion of white smoke caused by water vapor floating out of the cooling tower. This is a normal phenomenon that does not require panic during use.mteCooling tower noise reduction treatment manufacturer
