Limestone wet desulfurization is currently the most widely used in flue-gas desulfurization technology. However, during the limestone wet desulfurization process, foam problems often occur. During the circulation spraying process, limestone slurry is prone to foam due to mechanical effects such as stirring and gas involvement. Therefore, the emergence of limestone wet desulfurization defoamer can quickly solve the foam problem.

One of the main mechanisms of limestone wet desulfurization defoamer is to reduce the surface tension of the liquid. The defoamer molecules have a special structure that can spread quickly on the foam surface. When the defoamer molecules spread on the foam surface, they will replace the original surfactant on the foam surface, reducing the local surface tension of the foam.

In addition to being able to quickly eliminate existing foam, limestone wet desulfurization defoamer also can control foam regeneration. It can prevent air from entering the slurry again to form new foam, and it can also prevent the surfactant in the slurry from triggering the generation of foam again, thereby maintaining the stable operation of the desulfurization system.

The limestone wet desulfurization defoamer must be compatible with various components in the system, such as limestone slurry, additives, etc. If the compatibility is not good, it may cause the slurry properties to change, affect the desulfurization effect, and even damage the desulfurization equipment.

Limestone wet desulfurization defoamer plays a vital role in solving the foam problem in the limestone wet desulfurization process. Correctly selecting and using the right defoamer can not only improve the desulfurization efficiency and ensure the stable operation of the desulfurization system, but also meet environmental protection requirements and promote the entire desulfurization industry to develop in a more efficient and environmentally friendly direction.
