In the flue gas desulfurization system of power plants, foam treatment is an important link. In the flue gas desulfurization process, limestone or gypsum is usually used to absorb the sulfides in the flue gas and produce gypsum slurry. However, gases and suspended matter in these slurries can cause foam formation, affecting the desulfurization effect and system operation. To solve this problem, flue gas desulfurization defoamers are introduced into the desulfurization system of power plants.
1.Foam control: flue gas desulfurization defoamer can effectively destroy the bubbles and foam in the slurry, so that it can dissipate quickly. This helps to improve the stability and efficiency of the scrubberization system and reduces foam interference to equipment and systems.
2.Improve the desulfurization effect: The presence of foam will reduce the desulfurization effect and affect the absorption and conversion of sulfides in the gypsum slurry. By using flue gas desulfurization defoamer, the formation of foam can be effectively reduced, the desulfurization effect can be improved, and sulfide emissions can be reduced.
3.Protect equipment and systems: Foam can accumulate and build up in desulfurization equipment and pipes, potentially leading to clogging and damage. The use of flue gas desulfurization defoamer can effectively reduce these risks, reduce the frequency of equipment maintenance and replacement, and protect the normal operation of the power plant desulfurization system.
4.Improved safety: The presence of foam can lead to overflows and leaks, increasing safety risks for operators. The addition of flue gas desulfurization defoamer can help control the formation and spread of foam and reduce the probability of safety accidents.
It should be noted that it is very important to choose the right flue gas desulfurization defoamer. The appropriate defoamer should be selected according to the specific desulfurization process and system requirements and used in accordance with the instructions for use. In addition, attention should be paid to dose control when using flue gas desulfurization desulfurizer to avoid adverse effects on the desulfurization effect and system operation caused by excessive use. At the same time, regular inspection and maintenance of desulfurization equipment and removal of foam accumulation are also important measures to ensure the normal operation of the system.
