With the continuous development of modern industry and life, fire safety has attracted more and more attention. As one of the commonly used fire protection equipment, flame arrester is not only widely used in various places, but also in continuous improvement and upgrading. So, what is the basic principle of flame arrester? The following will give you a detailed introduction. The basic principle of

flame arrester

flame arrester is a device that prevents the spread of fire through physical or chemical action. It mainly relies on chemical reactions or physical effects to prevent the spread of flames and ensure safety. Common flame arresters include dry powder flame arresters, carbon dioxide flame arresters, foam flame arresters and water flame arresters. The basic principle of

dry powder flame arrester is to spray the dry powder containing the chemical reactant to the fire scene, so that the chemical reactant is combined with the flame and oxygen, thereby absorbing and consuming the heat and oxygen of the flame to prevent the spread of the fire. The basic principle of

carbon dioxide flame arrester is to inject compressed carbon dioxide into the fire scene, and dilute the concentration of oxygen, so that the flame cannot continue to burn and play a role in extinguishing the fire. The basic principle of

foam flame arrester and water flame arrester is similar, using liquid to cover the surface of the object, reducing oxygen contact and inhibiting accidents. The foam flame arrestor can also act as a physical isolation so that the liquid cannot burn.
Classification of
flame arresters

flame arresters can be classified according to the place of use and purpose. Common classifications are the following.

1. according to the use of place classification. Families, hospitals, schools, shopping malls, factories and other places need to be equipped with flame arresters.

2. by using the object classification. Flame arresters can also be classified according to applicable objects, such as commercial flame arresters and vehicle flame arresters.

3. Classified according to the purpose of use. Flame arresters can be divided into fire extinguishing type, prevention type, monitoring type, etc.
The use of
flame arresters

flame arresters are devices used to contain and extinguish fires. When using a flame arrester, you need to pay attention to the following points:

1. According to the type of fire, choose the appropriate flame arrester.

2. Determine the direction and distance to use the flame arrester.

3. Press the wrench firmly and spray the chemical or liquid to the fire source.

4. Ensure the safety of personnel and equipment.

Conclusion

flame arrester is a very important fire protection equipment, it can effectively protect the safety of personnel and the environment. The essence of a flame arrester is to prevent the spread of a fire by chemical or physical action. Different types of flame arresters are suitable for different occasions and uses. When choosing a flame arrester, we need to make a choice according to the actual situation and needs. In addition, the correct use of the method is also very important, only to comply with the use of norms, in order to achieve the best fire prevention effect.
