The use of defoamers is a critical part of the day-to-day operation of a power plant, especially when dealing with the large amounts of foam generated during power generation. The main function of defoamers is to inhibit the formation of foam and prevent excessive foam from adversely affecting power plant operations. This article will detail how power plants use defoamers to ensure a smooth power generation process.
First, the power plant needs to understand why the foam is generated. In power generation, foam is usually created due to the interaction of water with surfactants. These foams can accumulate in the water, affecting the normal flow of water and the efficiency of heat transfer, which in turn affects the efficiency of power generation. Therefore, power plants need to take measures to control the formation of foam.
Second, power plants need to choose the right defoamer. The choice of defoamer should be determined according to the specific situation of the power plant and the cause of foam. Generally speaking, defoamers should have the following characteristics: high efficiency, fast, stability, long-lasting, environmental protection and safety. When selecting a defoamer, power plants should consider factors such as their ability to inhibit foam, solubility in water, thermal stability, and compatibility with equipment.
After selecting the right defoamer, the power plant needs to determine the optimal amount and how to add it. In general, the amount of defoamer added should be adjusted according to the actual situation to achieve the best defoaming effect. At the same time, the power plant needs to choose the appropriate addition method, such as ** addition or intermittent addition. **Add-ons are for plants in continuous operation, while intermittent add-ons are for plants that are operating intermittently.
When adding defoamers, power plants need to pay attention to the following:
1.Ensure safe storage and transportation of defoamers to prevent leakage and mixing.
2.Before adding a defoamer, the water should be pretreated to reduce the amount of impurities and surfactants in the water.
3.Add the defoamer in strict accordance with the specified instructions for use, and pay attention to observe and control the addition process.
4.Waste liquids and residues are cleaned and disposed of in a timely manner to avoid adverse effects on the environment and equipment.
In addition, power plants should regularly check the effectiveness of defoamers to ensure that they are effective in inhibiting foam formation. If the defoamer is found to be ineffective or has other problems, measures should be taken to adjust or replace it in time. At the same time, power plants should pay attention to the development of defoamers, so as to understand and adopt more efficient and environmentally friendly defoamer products in a timely manner.
In conclusion, the use of defoamers in power plants is of great significance to improve power generation efficiency and ensure the stability of the power generation process. By understanding the causes of foam, selecting the right defoamer, determining the best amount and method of adding, and regularly checking the effectiveness of the defoamer, power plants can better manage the use of defoamers, improve power generation efficiency and reduce operating costs. At the same time, power plants should also pay attention to environmental protection requirements and choose environmentally friendly defoamer products to reduce the negative impact on the environment.
