[0102] (4) After cleaning is completed, close the first steam valve 105, the second steam valve 117 and the third steam valve 109, open the first discharge port valve 106, the second discharge port valve 118 and the third discharge port valve 110, and rinse the first cylinder pipeline 103, the second cylinder pipeline 115 and the series pipeline 107 with clean water.

[0103] Detection of cleaning effect of cylinder pipeline:

[0104] After cleaning, the first material cylinder pipeline 103, the series pipeline 107 and the second material cylinder pipeline 115 are rinsed with clean water, and water samples are taken from the first discharge port, the second discharge port and the third discharge port to detect the total iron content in the water using o-phenanthroline spectrophotometry.

[0105] Comparative Example 1

[0106] Cylinder pipe cleaning method:

[0107] Flush the pipe with detergent for 30 minutes.

[0108] Detection of cleaning effect of cylinder pipeline:

[0109] After cleaning, water samples were taken at the discharge port and the total iron content in the water was detected using o-phenanthroline spectrophotometry.

[0110] The results of the cleaning effects of the cylinder pipes in Example 1, Example 2 and the comparative example are shown in Table 1 below:

[0111] Table 1

[0112] Label Iron content Remark Example 1 0.5mg / ml No obvious findings Example 2 0.4mg / ml No obvious findings Comparative Example 3mg / ml Tiny rust or chemical material particles can be found in water samples

[0113] From the results of the tests on the cleaning effects of the cylinder pipelines in Example 1, Example 2 and the comparative example, it can be seen that the cleaning effects on the cylinder pipelines in Example 1 and Example 2 are better.
