Analysis and soultions of scaling in screw compressor for high-density polyethylene powder conveying
The high fine powder content in the inlet protection filter of the screw compressor for powder conveying in high-density polyethylene unit and the scaling in the compressor rotor lead to difficulties in cranking and compressor rotor locking.The causes of scaling in the screw compressor were analyzed and solutions were offered based on the actual operating conditions of the unit.The results show that the scaling in the screw compressor rotor is successfully solved by adjusting the process operating parameters of the high-density polyethylene unit to reduce the content of polyethylene fine powder and replacing the protective filter to reduce the amount of polyethylene fine powder passing through,ensuring the safe operation of the screw compressor.
