Foaming of desulfurization slurry is one of the common problems of power plant desulfurization system. Foam not only pollutes the on-site environment, but also easily causes negative effects such as corrosion on absorption tower equipment, and bubbles in the slurry can cause "false liquid level", plus agitator. Disturbances such as the ingress of oxidizing wind and other disturbances often cause fluctuations in the liquid level, resulting in bubbling and overflow of the liquid level. In case of foaming problems, measures can be taken in time to add power plant desulfurization defoamer to control the foam, and the foaming and overflow phenomenon can be effectively contained.

Power plants generally worry about when they choose to use defoamers:
①The defoaming agent cannot reduce the surface tension quickly, and the defoaming speed is slow
②Whether the addition of defoamer affects the normal operation of the desulfurization system, and whether the exhaust gas index does not meet the standard.
③A large amount of defoamer is toxic, corrosive and has side effects.
④The effect of defoamer in acid, alkali, electrolyte and hard water is not stable enough.
⑤ Whether it is resistant to high temperature, short foam suppression time and high cost.
⑥Whether it will affect the desulfurization device.

The Nanhui defoamer manufacturer has developed and designed the desulfurization defoamer for power plants according to the characteristics of easy foaming in the desulfurization system, which can eliminate the false high liquid level caused by the foam, prevent the slurry from overflowing, and slow down the heat exchanger fouling caused by the foam. The clogging problem can well eliminate the foam in the desulfurization slurry.
The power plant desulfurization defoamer developed by Nanhui defoamer manufacturer has the following product advantages:
- Independent research and development by powerful manufacturers, the defoaming formula is easy to use. Provide one-to-one solutions, which can be customized according to customer needs, and the defoaming effect is ideal.
- The defoamer has a relatively stable effect, can withstand high temperature and acid-base environments, and is suitable for use in desulfurization systems such as limestone desulfurization, flue gas desulfurization, natural gas desulfurization, power plant desulfurization, and steel mill desulfurization.
- The concentration of defoaming agent is high, and the dosage is very small. The general dosage is about one-thousandth to three-thousandths of the foaming system. The specific dosage can be tested according to the experiment.
- Free samples can be provided, and the above experimental test
- The desulfurization defoaming agent of Nanhui Power Plant is biologically inert, will not affect the desulfurization slurry, and has no effect on the desulfurization system
