Common design errors in dilute phase pneumatic conveying systems
In dilute phase pneumatic conveying, if the design is not reasonable enough, it is particularly prone to pipe blockage. Below, Juheng will share with you the design errors that may lead to pipe blockage.
in the process ofDilute phase pneumatic conveying systemCommon design errors encountered during troubleshooting include:
The insufficient length of the acceleration line provided by the pipeline between the first bend and the feeding point may cause premature line blockage, especially at higher loads or near optimal transition speeds.
2. Insufficient linear length to provide acceleration for the material between the feeding point and the first bend. This may lead to premature pipeline blockage, especially at higher loads or near optimal transition speeds.
3. Too many bends and the use of flexible pipes have resulted in a decrease in flow velocity and flow rate.
4. Excessive use of elbows and flexible hoses resulted in increased pressure drop or low pressure conveying capacity.
5. Adopt an upward sloping conveyor line to shorten the conveying distance.
6. Using back-to-back bending may cause the material to travel slower in the second bend and potentially block the pipeline.
7. Failure to accurately explain the air leakage of the rotary airlock/feeder. As the usage time increases, the leakage will also increase with wear and tear.
Improper exhaust of the rotating feeder can also cause blockage.
9. A pickup design that generates low-speed areas, allowing for material accumulation and unstable entrainment.
10. Failure to consider the temperature increase of the blower caused by compression heat. This can cause the conveying air to overheat, thereby reducing or softening the material and potentially leading to blockage.
11. Line losses in pipelines, elbows, dust collectors, mufflers, heat exchangers, and filters can lead to undersized air propellers.
11. Failure to consider the line losses of air ducts, heat exchangers, mufflers, and filters in the overall delivery pressure will result in the air thruster being too small in size.
Using a blower working pressure that is too close to the safety valve setting may result in intermittent loss of air delivery.
13. Lack of instruments (pressure, temperature, and flow measurement) makes it difficult to troubleshoot, identify potential issues, or optimize the system after startup.
14. Using a blower that is too small in size at high speeds and close to the motor horsepower limit will hardly cause pressure drop errors or expected differences in material properties.
