industrial dehumidifier dehumidification process flow chart
Let's learn about the next dehumidifier technology.
Dehumidifier workflow
The working process of the rotor dehumidifier can be divided into several parts:
Pre-cooling/pre-heating (optional part) - Rotor dehumidification - Post-cooling/post-heating (optional part)
Pre-cooling/pre-heating:
The use of chilled water to reduce the temperature of the air, so that the air in the cooling process, the relative humidity gradually close to saturation, at the required temperature, higher than the saturation of the air temperature will precipitate excess water, please AY is a cooling and dehumidification purposes.
Rotor dehumidification:
Dehumidifying rotor in the dehumidification area through the sealing system is divided into treatment area and regeneration area. The dehumidifying rotor rotates slowly at a rate of 8-10 revolutions per hour to ensure that the entire dehumidification process is continuous.
As the treated air passes through the treatment zone of the rotor, water vapor is absorbed by the hygroscopic medium in the rotor and the water vapor undergoes a phase change and releases latent heat. Due to the adsorption of a certain amount of water, the rotor also tends to be gradually saturated. At this point, the treated air becomes dry and hot due to its own moisture and latent heat release. Air.
Meanwhile, in the regeneration area, other air passes through the regeneration heater and becomes high temperature air (usually 100-140 degrees), which passes through the saturated runner after absorbing moisture, causing the absorbed moisture in the runner to evaporate, thus restoring the humidifying capacity of the d runner. And the humid air is removed by a regeneration fan.
The most important part of the dehumidifier as a rotary adsorption dehumidifier is the dehumidifying rotor. The rotor is made of glass fiber and heat-resistant ceramic material as the inner support carrier of the rotor, and special super-efficient hygroscopic media material (e.g., high-efficiency silica gel) is synthesized by multi-channel processing technology. In this way, the special honeycomb structure of the runner not only ensures the huge surface area of the runner in contact with air, but also improves the moisture absorption efficiency and increases the moisture absorption capacity of the runner.
After cooling/heating:
Use cooling or heating to control the air supply temperature.
