Solutions for large pressure fluctuations in the polypropylene powder conveying system? ?
Thread Content
During high-load operation in polypropylene production, large pressure fluctuations occur in the powder conveying system, which causes the powder conveying compressor to shut down frequently due to high outlet pressure. Does anyone have any good suggestions on how to control this and keep the outlet pressure of the powder conveying compressor stable? ? ?
What kind of craftsmanship do you have? We’ve encountered this situation before as well; we need to find a way to stabilize the material feeding
Is it dilute-phase transport or dense-phase transport? Is the transport volume the same?
Novlen gas-phase polymerization process
As far as I know, the Novlen process is only used by companies such as Fujian United, Formosa Plastics, Jinxi, and Shenhua Ningmei. Are you not one of those companies?
It is mainly caused by uneven material feeding. Check the exhaust condition of the balance line of the material valve; if the rotation speed of the valve is uneven, try switching to manual control of the speed. The degassing effect of the material is poor, with a high content of hydrocarbon gases and high static electricity, which leads to caking
