The phenomenon of material leakage in high salt wastewater evaporators during operation may be caused by various factors. Here are some main reasons and explanations:

        1. Improper feeding control:

        Excessive feeding during startup: Excessive feeding at once can cause the liquid level in the separator to be too high, making compressed air operation difficult and prone to material leakage. Insufficient feed during normal operation: If the feed amount is less than the sum of the discharge amount and the evaporation water amount, it will also cause the liquid level in the separator to be too high, leading to material leakage.

        2. Abnormal vacuum degree:

        Excessive or sudden increase in vacuum degree: In practical operation, if the vacuum degree is not properly controlled, excessive or sudden increase can lead to material running phenomenon.

        3. Equipment malfunction:

        Bottom leakage of concentration equipment: If there is a leakage problem at the bottom of the high salt wastewater evaporator concentration equipment, it will cause serious jumping of the material liquid and overflow. Secondary steam pipeline corrosion: Pipeline corrosion may cause steam leakage, affecting the normal operation of the system and indirectly leading to material leakage.

        4、 Weld seam and sealing issues:

        Weak links such as equipment and pipeline welds, flanges, sealing fillers, etc.: If there are defects or aging in these parts, it may lead to material leakage, resulting in material leakage. To reduce the occurrence of material running, the following measures can be taken:

        Strictly control the feeding amount: ensure that the feeding amount is moderate during start-up and normal operation, and avoid excessive liquid level in the separator.

        Stable vacuum degree: Based on actual operating conditions, control the vacuum degree reasonably to avoid excessive or sudden increases.

        Regular inspection and maintenance: Regularly inspect and maintain the equipment to promptly detect and address issues such as bottom water leakage and pipeline corrosion in the concentration equipment.

        Strengthen the management of welds and seals: Regularly inspect and maintain weak links such as welds, flanges, and sealing fillers in equipment and pipelines to ensure their integrity. In summary, there are various reasons for the occurrence of material leakage during the operation of high salt wastewater evaporators, and it is necessary to comprehensively consider various factors and take corresponding measures to solve them.
