近年来,国内管道清洗技术发展迅速,但目前常用的高压清洗、化学清洗等技术仍存在缺陷,高压管道清洗技术有哪些需要改进的地方?详细介绍了管道高压清洗的弊端。
  In recent years, the domestic pipeline cleaning technology has developed rapidly, but the commonly used high-pressure cleaning, chemical cleaning and other technologies still have defects. What needs to be improved in high-pressure pipeline cleaning technology? The disadvantages of high-pressure pipeline cleaning are introduced in detail.
  脱硫酸气管道堵塞后,采用高压水枪冲洗法。这个方法是严格的。直管间距小于10m, u型管两端切断,法兰连接有利于检测冲洗效果。
  After the pipeline of desulfurized acid gas is blocked, the high-pressure water gun flushing method is adopted. This method is strict. The distance between straight pipes is less than 10 m, both ends of U-shaped pipes are cut off, and flange connection is conducive to the detection of flushing effect.

  这项法律存在一些问题:
  There are some problems with this Law:
  (1)冲洗前,应通过堵塞盲板的方法,切断冲洗段管线和运行管线。
  (1) Before flushing, the pipeline in flushing section and operation pipeline shall be cut off by blocking the blind plate.
  (2)根据冲洗规定,需要将管道切割成段,然后焊接法兰。
  (2) According to the flushing regulations, it is necessary to cut the pipe into sections and then weld the flange.

  (3)管路四周留有DN200的水平空间,有利于冲洗时避免管路在冲洗段的安装位置,允许冲洗高压水枪进入管路进行高压水清洗。
  (3) DN200 horizontal space is reserved around the pipeline, which is conducive to avoiding the installation position of the pipeline in the flushing section during flushing, and allowing the flushing high-pressure water gun to enter the pipeline for high-pressure water cleaning.
  由于维修时间的限制,水枪的压力不能完全破坏硬块,导致冲洗不彻底,导致冲洗效果不佳。
  Due to the limitation of maintenance time, the pressure of water gun can not completely destroy the hard block, resulting in incomplete flushing and poor flushing effect.
  冲洗后,在酸性气体管道连接过程中,存在法兰连接不紧、酸性气体泄漏的隐患。在洗涤过程中,杂质残渣和污水容易造成环境污染。
  After flushing, there are hidden dangers of loose flange connection and acid gas leakage in the process of acid gas pipeline connection. In the washing process, impurity residue and sewage are easy to cause environmental pollution.
  中国的管道问题一直受到市政环保人员的困扰,这也是由于过去对管道的管理不善。
