How to prevent scaling on the surface of screw compressor rotors
Thread Content
Gas is compressed using screw compressors, and due to the presence of small particles of sodium carbonate and moisture in the gas, scaling or deposit formation occurs on the inner walls of the compressor’s inlet and outlet, as well as on the surface of the rotor. This results in the rotor being unable to rotate after the compressor stops operating; therefore, it is necessary to disassemble the compressor in order to manually clean the surfaces of the screws. May I ask how such problems can be solved fundamentally?
Isn’t there a self-cleaning filter at the inlet? This issue can be effectively eliminated.
Before each shutdown, a solvent compatible with the process medium can be introduced, provided that it does not contaminate downstream processes.
