Flue gas desulfurization defoaming agent
During the flue gas desulfurization process, the reason why a large amount of foam is generated is that the absorbent slurry reacts with sulfur dioxide to form compounds such as calcium sulfide, which causes a large number of bubbles to be generated in the slurry, thereby forming foam. These foams not only affect the normal operation of the flue gas desulfurization device, but also cause damage to the equipment and reduce desulfurization efficiency. Therefore, the use of flue gas desulfurization defoaming agents can effectively eliminate foam and ensure the normal operation of the flue gas desulfurization device.
Flue gas desulfurization defoaming agents usually use ingredients such as surfactants and anionic surfactants, which have excellent defoaming properties. Its molecular structure contains hydrophobic groups and hydrophilic groups, which can form hydrogen bonds, reduce surface tension, and cause foam to burst. In addition, the flue gas desulfurization defoaming agent also has shear resistance and high temperature resistance, and can work normally under high-speed stirring and high-temperature conditions.
The advantages of using flue gas desulfurization defoaming agents mainly include:
1. Eliminate foam and protect flue gas desulfurization equipment;
2. Improve desulfurization efficiency and reduce pollutant emissions;
3. Save energy and reduce operating costs;
4. Improve the working environment and reduce the impact on workers’ health.
Therefore, it is very necessary and important to use flue gas desulfurization defoaming agent during the operation of flue gas desulfurization equipment. When selecting a flue desulfurization defoaming agent, appropriate formulas and specifications should be selected based on specific process conditions and requirements to ensure that it has good defoaming performance and stability. At the same time, attention should also be paid to the correct use and storage of defoaming agents to ensure their long-term and effective working condition.
