Since most of the tube sheet orifices are welded or expanded, process defects and complex overcurrent media often cause corrosion and stress cracks at the nozzle, resulting in leakage at the nozzle; most of the traditional solutions are to use disassembly, welding, repair or blockage. The pipeline method, which not only fails to solve the fundamental problem, but also reduces the working efficiency of the carburetor, can only invest a huge amount of money to scrap and replace the new parts.
Long-term operation of the vaporizer will cause the equipment to be blocked by scale, which will reduce efficiency, increase energy consumption, and shorten lifespan. If the scale cannot be removed in time, there is a risk of equipment maintenance, downtime or scrapping for replacement. For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc., have many problems when cleaning oxygen compressors: they cannot completely remove deposits such as scale, and cause corrosion to the equipment. The residual acid will cause secondary corrosion or under-scale corrosion to the material, leading to the replacement of equipment. In addition, the cleaning waste liquid is toxic and requires a lot of capital for waste water treatment.
