Clogging of the gas phase tube

The acetylene generator in our company has been in operation for 4 years, with no blockages in the gas pipelines occurring. The process starts at the gas outlet of the acetylene generator, passes through a mud washer and a positive water seal, then goes through the acetylene cooling tower before reaching the gas holder or being fed into a compressor for pressurization; after that, it is purified with sodium hypochlorite and sent out of the facility. The generator main pipe is DN900, which reduces to DN600 after compression, with a designed production capacity of 120,000 tons of vinyl chloride per year. The liquid phase in the cooling tower is recycled water, and there have been two instances of filler blockage.
The gas phase pipeline is not clogged; rather, the liquid return pipeline is severely scaled.
