Thermal power plant defoamer is a kind of defoamer specially used in thermal power plants, which can effectively eliminate all kinds of foam generated in thermal power plants and ensure the normal operation of thermal power plants. Below we will introduce in detail the definition, function, types, use methods and precautions of defoamers for thermal power plants.
1. Definition of defoamer for thermal power plants.
Thermal power plant defoamer is a chemical agent that is mainly used to eliminate various foams produced in thermal power plants. During the operation of thermal power plants, due to various reasons, such as poor coal quality, incomplete combustion, water quality problems, etc., a large number of foams will be generated, which will have a certain impact on the normal operation of thermal power plants, such as reducing thermal efficiency and increasing equipment wear. Therefore, it is necessary to use thermal power plant defoamers to eliminate these foams and ensure the normal operation of thermal power plants.
Second, the role of defoamer in thermal power plants.
The main function of defoamers in thermal power plants is to eliminate all kinds of foam produced in thermal power plants. Specifically, it can be achieved in the following ways:
1.Reduces the surface tension of the foam, making the foam unstable and prone to bursting;
2.Change the viscosity of the foam so that the foam becomes easy to flow, so that it is not easy to accumulate on the surface of the equipment;
3.Inhibits the formation of foam, thereby reducing the impact of foam on thermal power plants.
By using defoamers in thermal power plants, the problem of excessive foam in thermal power plants can be effectively solved, and the operating efficiency and stability of thermal power plants can be improved.
3. Types of defoamers for thermal power plants.
There are many types of defoamers for thermal power plants, and the common ones are as follows:
1.Polyether defoamer: Polyether defoamer is a non-ionic surfactant with excellent defoaming performance and stability, suitable for thermal power plants under various water quality and temperature conditions.
2.Silicon defoamer: Silicon defoamer is an organosilicon compound with excellent defoaming effect and high temperature resistance, suitable for high-temperature, high-pressure thermal power plants.
3.Mineral oil defoamer: Mineral oil defoamer is a natural mineral oil with excellent defoaming effect and stability, suitable for thermal power plants under various water quality and temperature conditions.
Fourth, the use of defoamer in thermal power plants.
The method of using defoamers for thermal power plants varies depending on the type and manufacturer, but in general, the following steps can be followed:
1.According to the actual situation of the thermal power plant, select the appropriate type and concentration of defoamer;
2.Add the defoamer to the corresponding parts of the thermal power plant, such as circulating water system, water supply system, etc.;
3.Adjust the amount and frequency of defoamer according to the defoaming effect to achieve the best defoaming effect.
It should be noted that the amount of defoamer should not be used too much, otherwise it may have a certain impact on the operation of thermal power plants. Therefore, when using defoamers, they need to be adjusted and optimized according to the actual situation.
5. Precautions for defoamers for thermal power plants.
When using defoamers for thermal power plants, the following points need to be noted:
1.Choose the right type and concentration of defoamer and avoid using excessive or unsuitable defoamer;
2.Before adding the defoamer, it needs to be stirred well to ensure that the defoamer can be evenly dispersed in the water;
3.Regularly check the use effect of the defoamer, and adjust and optimize it according to the actual situation;
4.Pay attention to the safety of defoamers to avoid harm to the human body and the environment.
In short, thermal power plant defoamer is an indispensable chemical agent in thermal power plants, which can effectively eliminate all kinds of foam generated in thermal power plants and ensure the normal operation of thermal power plants. When using defoamers, it is necessary to select the appropriate type and concentration, and pay attention to the application method and precautions to ensure that the defoamer can exert the best effect.
