Description

Technical Field

[0002] In process production, a large amount of waste gas and waste water are usually generated. In order to discharge them safely, waste gas pipes and waste water pipes are needed. If the conveying fan in the production workshop adopts fixed frequency control, the pressure in the branch pipe section of the workshop will also change with the fluctuation of the exhaust gas emission volume. There is a risk of leakage due to unstable exhaust gas pressure in the branch pipe section. Therefore, the waste gas pipe needs regular maintenance. However, the waste gas transmission pipeline is generally long, the pipeline is complex, and the gas flow rate is fast. If static electricity is generated in the pipeline, such as a large amount of static electricity accumulation, it will cause explosions and other safety accidents. Therefore, conventional cleaning methods are not competent for this task.

[0003] Therefore, when purifying the pipeline, the spray method and the electrical condensation method are usually used to clean the exhaust gas pipeline. During the cleaning process, it is also necessary to ensure that there will be no leakage or overflow. However, when designing many pipelines, due to the limitations of the factory building, many changes in route and diameter will be made. This results in the spray equipment being unable to be used effectively. In addition, in many pipelines, some impurities will adhere to the inner wall of the purification pipeline, which results in some purified gases or liquids being unable to be fundamentally removed.
