Why do power plants use desulfurization defoamer?
In the power generation of thermal power plants, the frequent occurrence of foam hinders the progress of desulfurization and reduces the work efficiency. Therefore, adding desulfurization defoamer is an essential step in desulfurization operations.
Then, why should we remove the foam in the slurry? Why can limestone desulfurization defoamer eliminate foam?
Below, we will learn more about it through the article.
Why remove limestone slurry foam?
Limestone slurry, as a composite liquid, contains a large amount of surfactants or certain active ingredients, and the interior of the slurry is extremely unstable. It is easy to produce insoluble gas under the influence of external stimulation, and rise to the liquid surface under the influence of buoyancy to form foam.
The overflow of the foaming system causes waste of raw materials and environmental pollution, as well as problems such as ash accumulation at the inlet of the absorption tower, which increases production costs and seriously affects the efficiency and effectiveness of desulfurization. Therefore, the removal of foam is very necessary.
Why can desulfur antifoam eliminate foam?
1. Defoamer for electric power plant is a lotion defoamer with polyether as the component, which can be directly added into the limestone slurry to restrict the foam generated in the absorption tower.
2. Desulfurization defoamer have strong acid and alkali resistance, high temperature resistance, and can still achieve excellent results in harsh working environments such as absorption towers.
5. Desulfur antifoam can achieve rapid defoaming and long-term foam suppression. The addition of defoamer can effectively control the liquid level in the tower, eliminate the phenomenon of slurry overflow, improve the efficiency of wet desulfurization, and increase the stability of the entire desulfurization system, making the desulfurization
