Thermal rotary film deaerator
Thread Content
Who has the internal and external structure diagrams, as well as the working principle of a thermal rotary film deaerator? Could you share it with me? Thank you all for your help!

In a container, the amount of gas dissolved in water is proportional to the partial pressure of the gas above the water surface. Thermal deaeration is employed, which involves using steam to heat the feed water and raise its temperature. This increases the partial pressure of steam above the water surface, while the partial pressure of dissolved gases decreases gradually. As a result, the gases dissolved in the water escape continuously. When the water is heated to its boiling temperature at the corresponding pressure, the water surface is entirely covered with water vapor; the partial pressure of dissolved gases becomes zero, and the water loses its ability to dissolve gases. In other words, all gases dissolved in the water, including oxygen, can be removed. The efficiency of deoxygenation depends, on the one hand, on whether the feed water is raised to its boiling temperature at the corresponding pressure, and on the other hand, on the rate at which dissolved gases are removed – a rate that is closely related to the size of the contact surface area between water and steam. Our device is generally controlled at 104°C and 20 kPa
