kelishi丨How to solve the problem of inability to discharge dust in the pneumatic conveying system?

  • Categories:News Center
  • Time of issue:2022-05-06 10:40

(Summary description)When encountering the problem that the pneumatic conveying cannot discharge the dust, it is necessary to check the operation of the pneumatic conveying and whether the equipment is damaged. The dust removal system of the pneumatic conveying system usually consists of material conveying valves, feed check valves, conveying pipes and valves, and ash separation equipment. , ash storage and auxiliary equipment, negative pressure fan and control system.   The following factors can be considered to cause the dust of the pneumatic conveying system not to be discharged: 1. Incorrect setting of dust collector blowing It may be caused by low compressed air pressure, blockage in the pipeline, etc. Therefore, the problem can be eliminated by increasing the injection frequency, increasing the pressure, or cleaning the dust collector. 2. Failure of the injection valve Check the diaphragm valve, or control the solenoid valve to correct the problem. 3. The pulse controller fails If there is no dust discharge due to the failure of the pulse controller, check whether the controller indicates each contact, or check whether the output of each terminal is in normal operation. 4. The filter bag is blocked If the dust collector fails due to the blockage of the filter bag, the problem can be solved by cleaning the filter bag or replacing the filter bag. In addition, in the subsequent production process, the air volume should be reduced, the compressed air pressure should be increased, and the cleaning frequency should be increased, etc. measures to solve the problem. 5. Filter bag leakage If the filter bag is damaged or torn and other reasons cause powder leakage, the filter bag should be replaced; if the powder leakage is caused by the poor sealing, the installation of the spring ring should be checked to ensure that it is tight.
