Description

Technical Field

[0001] This utility model relates to the field of petrochemical industry technology, and more specifically, to a fireproof and shockproof steel frame explosion relief plate for petrochemical industry. Background Technology

[0002] In the petrochemical industry, fire-resistant and shock-resistant steel-framed explosion relief panels are an important protective device to ensure equipment safety. They are designed to quickly release pressure when encountering excessive internal pressure or explosion risks, while also providing fire resistance and shock resistance to protect personnel and equipment. Among them, the concave explosion relief panel is characterized by its concave shape. This design has specific advantages in certain applications such as reactors and storage tanks. A concave explosion relief panel generally consists of a concave-shaped panel and a steel frame support. Due to its sensitive characteristics, the concave explosion relief panel can respond promptly to changes in internal and external pressure, ensuring safety performance in high-risk environments.

[0003] The main function of existing concave explosion relief panels is to rupture rapidly when the internal pressure exceeds the design threshold to release pressure and protect equipment and personnel. This rupture mechanism and purpose determine that once activated, they cannot be reused. Once a concave explosion relief panel has experienced overpressure and ruptured, its shape, strength, and sealing performance will be damaged and cannot be restored to its original state. Even if the surface appears intact, the structural integrity will be affected. They are usually designed as single-use safety devices and cannot be reused multiple times, increasing the cost of use. In view of this, we propose a fireproof and earthquake-resistant steel frame explosion relief panel for the petrochemical industry. Utility Model Content
