Adsorption dryer regeneration gas volume adjustment

Adsorption dryer regeneration gas volume adjustment is an important link to ensure efficient operation and prolong service life of the dryer. The importance of regeneration gas volume, adjustment method, precautions and optimization analysis will be elaborated in the following.

Adsorption dryers dry compressed air through pressure changes. In the process of drying, a part of the compressed air will be decompressed and expanded atmospheric pressure, and this pressure change makes the expended air became drier, and flow through the desiccant layer that has absorbed enough water vapor to suck out the moisture in the desiccant, thus completing the drying process. So reasonable adjustment of regeneration gas volume is of great significance to ensure drying effect and improve drying efficiently.

• The regeneration gas volume adjustment ways

Initial Setup:

The regeneration gas volume of the absorption dryer is usually pre-adjusted to 5%~8% of processed gas volume at the factory. This ratio is an optimization result based on a large amount of experimental data, which can better balance the drying effect and energy consumption.

Manual adjustment:

The most of absorption dryers are equipped with manual adjustment valves like throttle valves, which can be find-tuned by the user according to actual needs. Counterclockwise rotation of the throttle valve can increase the amount of regeneration gas, while clockwise rotation reduces the amount of regeneration gas. However, it should be noted that this adjustment should be carried out under the guidance of technicians to avoid affecting the drying effect or damaging the equipment due to improper adjustment.

AI control system:

Some high-end adsorption dryers are equipped with intelligent control system, which can automatically adjust the regeneration gas volume according to the parameters of inlet temperature, pressure and humidity to realize more accurate drying control. This system not only improves the drying efficiency, but also greatly simplifies the operation process.

• Adjustment considerations

Avoid over adjustment:

Excessive increase in regeneration gas volume can improve the drying effect, but it will increase energy consumption and prime costs.

Pay attention conditions of intake air:

Conditions such as intake air temperature, pressure, humidity and so on have a direct impact on the demand for regenerated gas. Such as the higher intake air temperature, the greater amount of regenerated gas required. The lower intake air pressure, the more regenerated gas may need to be increased to compensate for the pressure loss. Therefore, changes in intake air conditions should be taken into account when adjusting the amount of regenerated gas.

Regular maintenance:

Absorption dryer will be affected by various factors during use, such as absorbent aging, filter blockage and so on, which may affect the adjustment effect of regenerated gas volume. Therefore, the equipment should be maintained regularly to ensure that the components are in good condition.

• Optimization analysis of regeneration gas volume regulation

Energy saving and consumption reduction:

On the premise of ensuring the drying effect, energy saving and consumption reduction can be achieved by optimizing the adjustment of the regenerated gas volume. For example, adopt zero-gas consumption compression heat regeneration technology can be regenerated without the need for additional compressed air. The AI control system allows for precise control of regenerated gas volume, which also avoids unnecessary waste.

Raise drying efficiency:

Reasonable regeneration gas volume adjustment can raise drying efficiency, shorten the drying cycle, thereby increasing the processing capacity and stability of the equipment. At the same time, by optimizing the pipe layout and flow rate design, pressure loss and airflow short circuit can also be reduced, and the drying effect can be improved.

Extend the life of equipment:

Overuse or improper regulation of regenerated gas volume can damage the adsorbent and shorten the life of equipment. Therefore, when adjusting the regenerated gas volume, the instruction manual and technical specifications of the equipment should be followed to ensure that the equipment is operating in the best condition.

All in all, the regulation of the regenerated gas volume of the absorption dryer is a complex and important work. Through reasonable adjustment methods and precautions, the efficient operation and service life of the equipment can be ensured; At the same time, the drying efficiency, energy saving and consumption reduction effect can be further improved through optimization analysis.
