Technical Field
The invention belongs to the field of petrochemical industry, and particularly relates to a petrochemical industry double-layer storage tank.
Background
The petrochemical industry plays an important role in modern industry and is widely applied to various fields such as energy, materials, cosmetics, medicines, pesticides, coatings, plastics and the like.
The petrochemical storage tank is a container for storing raw materials, intermediate products and finished products in the petrochemical production process. These tanks are typically made of metal (e.g., steel) or concrete, having different shapes and capacities to accommodate various storage requirements. The main function of the tank is to safely store liquids or gases, which act to store, regulate and dispense substances during petrochemical processes.
Petrochemical tanks can be divided into many types depending on their use and nature, such as raw material tanks, intermediate product tanks, finished product tanks, storage and transportation tanks, etc. These tanks need to be provided with a series of safety measures to prevent accidents such as leakage, spontaneous combustion, explosion, etc. Common security measures include leak detection systems, fire and explosion protection devices, temperature and pressure monitoring systems, and the like. In addition, the tanks also require periodic inspection and maintenance to ensure their structural integrity and safety performance.
The current petroleum storage tanks have a series of problems when leakage occurs, wherein the most obvious is that the leakage situation cannot be treated in time. Due to the lack of effective leak detection and control measures, leaks may continue to occur, resulting in the failure of the petroleum reservoir to be stopped in time, further increasing the size and duration of the leak. This delayed handling situation can cause serious environmental pollution and damage and can pose a threat to personnel safety.
Meanwhile, the leaked petroleum storage can cause high-temperature problem, so that the risk of spontaneous combustion of petroleum in the storage tank is greatly increased. Since petroleum is a flammable substance, once spontaneous combustion occurs, serious safety accidents such as fire and explosion can be caused. This risk of spontaneous combustion caused by high temperatures not only causes damage to the tank itself, but also causes further damage to surrounding facilities and the environment.
