Advantages and dosage of using defoamer in power plants
In the desulfurization process of power plants, foam problems often become a challenge that affects the efficiency of desulfurization and the operation of the equipment. These foams not only reduce the efficiency of desulfurization, but also may lead to liquid loss and equipment damage. In order to solve this problem, the use of specialized power plant desulfurization defoamer becomes an efficient and reliable solution. Power plant desulfurization defoamer is a special additive developed for the foam problem in the desulfurization process.
Desulfurization defoamer for power plant is a special additive developed for foam problem in desulfurization process. Its main components can rapidly reduce the surface tension of foam, make foam burst and inhibit the regeneration of foam. This not only helps to improve the desulfurization efficiency, but also can prevent equipment damage caused by foam.
The use of power plant desulfurization defoamer has many advantages.
1) Desulfurization defoamer for power plant can quickly eliminate foam, improve the environment of desulfurization operation, and avoid the adverse effects caused by foam overflow.
2) Desulfurization defoamer can improve the efficiency of desulfurization, so that coal-fired power plants more effectively control the emission of sulfur dioxide, in line with environmental standards.
3) Defoamer for power industry also has excellent thermal stability, can maintain stable defoaming effect under high temperature environment.
For different types of power plants, power plant desulfurization defoamer has corresponding models and dosage recommendations to ensure the best defoaming effect. At the same time, its use is simple, just add the defoamer antifoam directly into the desulfurization system, without any modification to the equipment or adding additional equipment.
How to add defoamer to achieve the desired effect
1) First of all, before adding antifoam , we must find its adding point, and generally choose to add it in the pit of the absorption tower;
2) Then add the desulfurization defoamer by intermittent regular impact dosing or continuous dosing by metering pump;
3) dosage: when foaming overflow occurs in the absorption tower, 0.8-1.2 kilograms should be added in a one-time impact dosage. At the beginning of adding defoamer is added in the absorption tower when foaming overflow occurs, this time you need to add a large amount of defoamer (generally based on the overall amount of 0.01% -0.03% of the amount added), behind the defoamer can be based on the composition of the amine liquid, the amount of flue gas, the composition of impurities and combustion process, the characteristics of the absorber, the amount of SO₂ to determine the amount of defoamer;
(4) the frequency of adding defoamer is generally based on the absorption tower foaming situation, generally add 1-2 times a day (but this is based on their own desulfurization process foaming situation)
In general, the power plant desulfurization defoamer is an effective solution for the foam problem in the desulfurization process of coal-fired power plants. It defoamer can quickly eliminate foam, improve the efficiency of desulfurization, and prevent equipment damage, providing strong support for the stable operation of the power plant and meet the emission standards.
