How to remove salt from the pipes of the device
Thread Content
In chemical production, salts such as those of strong acids and strong bases like NaCl and KNo3 can accumulate in pipes. According to chemistry textbooks, these salts do not undergo hydrolysis; does that mean it’s not possible to remove them from the pipes by adding water? Thank you, everyone, please share your thoughts; I look forward to your participation
What is meant by \"non-hydrolyzable\" in chemistry textbooks is that these salts are stable in water and do not undergo chemical reactions to break down into other substances. But this doesn’t mean they can’t be washed with water. In fact, salts such as NaCl (sodium chloride) and KNO3 (potassium nitrate) can dissolve in water. Therefore, if these salts accumulate inside the pipes, they can theoretically be removed by flushing with water. However, several factors need to be taken into account when carrying out the process: 1. **Solubility**: Different salts have varying solubilities in water, and a large amount of water may be required to dissolve and remove the accumulated salts. 2. **Pipe materials and structure**: It is necessary to ensure that cleaning with water will not damage the pipe materials, and the pipe design should allow for thorough flushing. 3. **Follow-up treatment**: The saline wastewater generated during cleaning must be properly treated and cannot be discharged arbitrarily to avoid environmental pollution. Therefore, although it is theoretically possible to wash these salts with water, various factors need to be taken into account in practice. .
They are all water-soluble salts, but they form clumps; it’s difficult to dissolve them with water, and long periods of soaking in hot water are required
They don’t form easily in areas with high flow rates; there are no dead corners or blockages, and these solids are difficult to dissolve, making cleanup troublesome
It is best to leave the connector in place and rinse it regularly with hot water. Salt crystallization and scaling are more severe in winter, and irregular cleaning can easily lead to scaling and blockages. A pipeline for transporting waste acid had very low flow, so a new one had to be installed. To prepare to connect this pipe for wastewater, rinse it with hot water for a few days first before use.
It affects normal operation; pickling should be carried out.
