The pressure required for compressed air drying varies depending on the application and the specific requirements. The following are the pressure ranges required for compressed air drying in several common application scenarios:
1. General Industrial Applications
- air pressure range: Under normal circumstances, the air pressure required for compressed air drying is between 2-8 Bar. This range is suitable for most industrial cleaning and blow-drying operations, such as dust removal on the surface of equipment, purging inside pipes, etc.
2. Specific Process Applications
- compressed air soot blowing: In the boiler room and other places, when using compressed air to remove the soot on the heating surface, the pressure should not be less than 0.7 MPa. The maximum working pressure can reach 1.0~1.6 MPa.
- plastic bottle blowing: The working pressure of compressed air for blow molding is usually high, generally reaching 3.0 MPa. This high pressure condition helps to blow the plastic bottle into the desired shape and size.
3. other considerations
- nozzle diameter: The choice of nozzle diameter will also affect the drying effect. Generally speaking, the diameter of the nozzle should be selected according to the size and shape of the object to be cleaned, and the common diameter is 2-5mm.
- gas dryness: Moisture and oil in compressed air will affect the drying effect. Therefore, in application scenarios that require high dryness, a dryer should be used to process the compressed air to ensure that its dryness meets the requirements.
In summary, the pressure required for compressed air drying varies depending on the application scenario and specific requirements. When selecting the pressure, the equipment performance, drying effect, safety and operating cost should be considered comprehensively. At the same time, attention should also be paid to maintaining the dryness of the gas to ensure the drying effect.
