Description

Technical Field

[0001] The invention relates to the technical field of petrochemical industry, and in particular to an adjacent tank temperature control system and an adjacent tank temperature control method. Background Art

[0002] In recent years, with the development of the petrochemical industry, the number of tanks in the tank area has increased and the scale has also become larger. When a tank catches fire, the hydrocarbon fire will release strong thermal radiation. Under the effect of thermal radiation, the adjacent tanks may experience the following situations: 1. The strength of the adjacent tanks decreases, the tank wall tears, and the liquid in the tank leaks, which leads to a fire; 2. The medium in the tank evaporates, the pressure in the tank increases, and a physical explosion occurs; 3. The medium in the tank evaporates, the pressure in the tank increases, and the gas in the tank is discharged from the breathing valve, etc., and it encounters a fire source and burns.

[0003] Therefore, when a fire occurs in a storage tank, it is necessary to protect the adjacent storage tanks to prevent the fire accident from spreading. The existing method of protecting adjacent tanks in the event of a fire is to apply water spray, that is, spray water on the surface of the adjacent storage tanks through a fixed water spray system or a mobile water cannon, and remove the heat through the flow and evaporation of water, thereby achieving the purpose of protecting the adjacent storage tanks.

[0004] The inventors of this application discovered during the process of realizing the present invention that the prior art solutions, due to not knowing the surface temperature of adjacent tanks, all manually determined the spraying position and spraying direction, and there was a problem of blind spraying. A large amount of fire water was continuously sprayed back and forth on the entire tank wall, resulting in a waste of fire water in some places with very low temperatures and insufficient fire water in some places with very high temperatures.
