Sodium carbonate pipeline cleaning related
Thread Content
Is it necessary to clean the pipeline through which sodium carbonate flows? Because the weather is cold and the pipeline is often blocked when sodium carbonate is not used, it may be caused by the crystallization of sodium carbonate. Please help me analyze it. Thank you!
Whether it is necessary to clean with water depends on the process requirements.: (1) How often is sodium carbonate used? Is it intermittent? If used periodically, a certain amount of fluid can be maintained through, making the fluid fluid. ； (2) If the pipeline is more important, it is better to add mixing heat ； (3) If there is no requirement for the concentration of sodium carbonate and it is just sent out as waste, you can also consider connecting hot water of a certain temperature. ； In this case, the main thing to note is: fluid flow and continuity ； Medium concentration ； medium temperature.
Give some suggestions to the landlord: 1. Consider using remote steam backflushing, which can effectively reduce changes in solution concentration. 2. If the volume of the solution preparation tank is large enough, you can consider using low-concentration solution for backflush. Through calculation, the concentration of the solution in the solution preparation tank will not be greatly affected.
Jianyi landlord adopts the following methods: 1. Change the pipeline process and the fluid circulates continuously. 2. When designing the pipeline, consider that the pipeline should be purged with water or steam during shutdown. 3. Reduce the concentration of the slurry and increase its temperature, that is, the solubility reduces the probability of crystallization.
