The difference between fire dike and dike

In the chemical industry, the construction of dams is an important link to ensure production safety. Due to the special nature of chemical products, the design and selection of materials for dykes require extra care. Among them, the two types of dams, fire dike and dike, are often mentioned, but they are obviously different in function and application. This paper will analyze the difference between fire dike and dike in depth to help professionals in the chemical industry to make scientific decisions.

1. basic definition and functional characteristics

1. Fire dike definition and function

The fire dike is a flood control facility in the form of a dam, and its main function is to block water and discharge flood. The elevation difference is formed by artificial or natural means to guide the flood to the downstream, thereby reducing the impact of flood disasters. Fire dike more use of earth and stone materials, its durable, relatively low cost, maintenance is more convenient.

2. Dike definition and function

Dikes are dikes used to block liquid leakage and are usually made of lightweight materials such as polypropylene or glass fiber reinforced plastic. Its main function is to prevent liquid or gas leakage, especially for flammable and explosive or toxic media storage sites. The design of the dike focuses on the portability and sealing of the material, which can effectively isolate the diffusion of the material.

CHARACTERISTIC COMPARISON WITH CHEMICAL EMBANKMENT DAM RELATED

1. Material characteristics

The fire dike is mostly made of earth and stone materials, which has high strength and durability and is suitable for long-term use. The dike is more use of polypropylene, glass fiber reinforced plastic and other lightweight materials, these materials are not only light weight, but also has good chemical resistance, suitable for frequent replacement.

2. Maintenance cost and cycle

The maintenance cost of the fire dike is low, and a simple inspection is usually carried out every year. The overall maintenance cost of the dike is more economical due to its light material, shorter maintenance cycle and lower replacement material cost.

3. Application scenarios and usage conditions

Fire dike is mainly used for flood control and drainage, and its use conditions are relatively simple. The dike needs to take into account the temperature, pressure, chemical composition and other complex factors of the storage medium, usually located at the edge of the factory or storage area.

Selection of embankment considerations

1. Process conditions

In chemical production, the use of the levee is more frequent, because the storage medium may contain dangerous substances, once the leakage of serious consequences. The fire dike is mainly used in the field of flood control.

2. Material adaptability

The selection of the material of the bank needs to consider the temperature, pressure and chemical composition of the storage medium. For example, the storage of flammable liquids in the bank is usually made of glass fiber reinforced plastic material, because of its high temperature resistance and good sealing. The dike for the storage of corrosive liquids may be made of polypropylene.

1. Implementation of standard requirements

According to different media and storage conditions, the design and construction standards of fire dikes and dikes will vary. Professionals in the chemical industry need to select the appropriate type and material of embankment according to the relevant standards.

Conclusion

There are significant differences between fire dike and dike in function and application, and it is very important to select the appropriate type of dike for the safety of chemical production. Although both of them can play the role of embankment, the application of embankment in chemical industry is more extensive and important. Professionals in the chemical industry should scientifically select the type of dam according to the specific process conditions and medium characteristics, so as to ensure production safety.
