[0002] Pipeline blowing is a cleaning process carried out to remove residual impurities inside the pipeline system after it has been installed and pressure tested. Dust will accumulate inside the pipeline after it has been used for a long time, so it is necessary to use pipeline blowing equipment to clean it.

[0003] Application No. CN202010131787.0 The present invention discloses a method for purging super-high-rise steam pipelines and a cooling water tank used therefor. The present invention performs purging according to the following procedure: find out the parameters of the steam pipeline to be purged → design a cooling water tank → make a cooling water tank → install a cooling water tank → purging operation → verification of purging results. The present invention avoids a large amount of steam overflow when performing steam purging. It effectively solves the problems of noise pollution and false fire alarms caused by the discharge of a large amount of steam in the prior art, and also avoids the pollution of the environment by steam containing impurities. The present invention does not require separate segmented flushing with tap water, saving equipment, materials, labor costs and time for segmented flushing. During purging, the steam during boiler commissioning and trial operation can be used to save purging resources. The method of the present invention is particularly suitable for cleaning steam pipelines in super-high-rise buildings.

[0004] Based on the search of the above patents and the understanding of the application of existing pipeline blowing equipment: the current pipeline blowing equipment is progressively forward in the process of supplying air to the inside of the pipeline, and the wind force will not directly clean the inner wall of the pipeline. Therefore, there are stubborn impurities on the inner wall of the pipeline and cannot be cleaned by progressive weak wind. Utility Model Content
