中文(简体)In the past, manual cleaning was commonly used when cleaning plate heat exchangers. Wire brush is one of the commonly used tools. Due to its time-consuming and labor-intensive nature, it has gradually been replaced by machinery. However, for some small manufacturers and situations where there are not many heat exchange devices, manual cleaning is still a common method. In fact, even with wire brushes for cleaning, mechanization can be achieved. There are reports that multiple wire brushes can be connected to a certain transmission device, driven by a motor, to clean the inner wall of the pipeline; In addition, there can be multiple wire brushes with a moving speed of about 0.25m/s, and the cleaning efficiency is about 4-5 times that of manual cleaning. The disadvantage of this method is that it can only clean the oxide layer with low hardness.
The wire brush in the above-mentioned cleaning machine can also be replaced with a scraper. The scraper can be connected to a flexible shaft to remove all parts of the oxide skin surface. But this device is only suitable for circular cross-sections and is not easy to clean the inner walls of non-circular cross-section pipelines or shells. As long as the appropriate scraper is selected, it can be used to remove oxide layers of different hardness without causing significant damage to the inner wall of the pipeline.
