In order to better develop the wet flue gas desulfurization technology, it is necessary to analyze in detail the reasons for the insufficient airflow of the desulfurization aerator fan and propose corresponding solutions to achieve unified operation of flue gas desulfurization, which is both economical and safe. The environmental and social benefits of operating desulfurization equipment. Today, Shengyuan Technology will introduce the control measures for desulfurization and oxygenation fans to prevent insufficient desulfurization and oxygenation fans.
Process management and control measures were implemented during the maintenance process. Only by better operating the desulfurization system can we ensure the safe and reliable operation of the equipment. If the unit flue gas is discharged to the standard level, the normal reaction mechanism of desulfurization must be maintained in order to absorb it. The tower slurry has been completely oxidized. When solving the problem of insufficient oxidation air, specific treatment plans should be developed and strictly controlled, and responsible persons should be identified to ensure that various operations can be carried out in accordance with production standards.
In order to ensure the normal operation of the desulfurization and oxidation air system, the following points must be noted:
1. The desulfurization system has been out of service for a long time, and the oxidation air pipeline needs to be regularly watered for maintenance;
2. Regularly replace the oxidation fan and flush the oxidation pipeline in a timely manner;
3. The temperature of the oxidizing air in the absorption tower is maintained at 30 ℃ -50 ℃;
4. During operation, the liquid level and slurry concentration of the absorption tower should be strictly controlled to avoid slurry saturation, thereby reducing the possibility of scaling to a certain extent.
5. Strengthen monitoring and maintenance to prevent large amounts of dust from entering the absorption tower and forming ash scale;
6. Strengthen the monitoring of desulfurization DCS screen and on-site oxidation fan pressure. These conditions are very helpful for operators to accurately determine the real-time conditions of equipment and systems. Once problems are identified, they can be resolved promptly.
