Description

Technical Field

[0001] This invention relates to the field of oil tank cooling control technology, and in particular to an automatic spray cooling control system and method for oil tanks. Background Technology

[0002] Existing factory oil tanks are all located outdoors. During hot weather, when the tank temperature becomes too high, industrial water is used for spraying to cool them down and maintain a stable temperature, ensuring safe operation. Current solutions involve operators manually opening the manual spray valve on-site during hot weather, and then closing the valve once the temperature has stabilized to avoid wasting water. However, insufficient valve opening results in a small water volume, leading to poor cooling and potential safety hazards. Conversely, excessive valve opening results in a large water volume, wasting water and hindering energy conservation. Furthermore, these systems rely on manual control, which lacks real-time adjustment and precise control. Therefore, providing an automatic spray cooling control system and method for oil tanks is a pressing technical problem that needs to be solved by those skilled in the art. Summary of the Invention
