Different cleaning methods should be adopted for the evaporator cleaning of high-salt wastewater according to different scaling modes. For example, calcium magnesium carbonate scale is easy to dissolve in strong acid, and the reaction releases carbon dioxide gas to generate substances that are easy to dissolve in water to achieve the purpose of cleaning and descaling. At present, there are two main ways to clean the evaporator of high-salt wastewater. Let's have a brief introduction.
1. Online cleaning: online cleaning technology is to ensure the normal operation of production while cleaning equipment. The whole system is equipped with automatic online cleaning function. The cleaning solution after cleaning is evaporated by the waste water, which does not affect the operation of the whole set of high-salt waste water evaporator.
2. Shutdown cleaning: when scaling is serious or the equipment needs to be shutdown, daily maintenance and cleaning shall be carried out for the high-salt wastewater evaporator. Different chemical and physical methods are used for shutdown cleaning according to different water quality and scale body.
The above is a brief introduction to the cleaning of high-salt wastewater evaporator. Practice has proved that regular cleaning of the evaporator for high-salt wastewater is conducive to the stable operation of the equipment.
