New Local Rapid Heating Technology and Working Principle for Oil Tank

Oil tanks play a very important role in the storage and transportation of oil and gas. In oil and gas storage, oil tanks are mostly used for oil storage. When oil is needed, it is exported from the oil tank. In the process of oil output, it is inevitable to encounter a problem where the oil becomes viscous due to low temperature, reducing its fluidity and preventing it from being smoothly output from the oil tank. How to solve this problem? It is reported that the new local rapid heating technology for oil tanks has effectively solved such problems.

working principle:
1. Insert the "eddy current hot film heat exchanger" radially into the bottom of the oil tank, with the heat medium (steam) flowing through the tube side and the oil flowing between the inner tubes of the shell side. The suction port of the shell is directly connected to the medium inside the tank.
2. A temperature control valve is installed at the steam inlet of the heat exchanger, and the steam inlet of the heat exchanger is controlled by detecting the temperature of the oil outlet through a temperature sensing probe, thereby ensuring a constant oil temperature.
The heat exchanger adopts high-efficiency heat exchange elements - vortex heat film tubes, which maintain the reasonable flow of oil between the tubes. The thermal efficiency is 3-5 times that of ordinary heat exchangers. Its enhanced heat transfer mechanism is: when the oil fluid flows on the inner and outer surfaces, it is designed to flow in turbulent flow, generating strong oscillation and scouring effects. The direction of flow constantly changes, and the high-temperature oil fluid that closely adheres to the surface of the tube wall is constantly replaced. The insulation layer becomes thinner and even destroyed, and the heat transfer on the metal surface is accelerated. The micro vortex of the fluid is strengthened, which enhances the internal heat diffusion of the oil fluid. It will not cause local high temperature overheating of the fluid close to the surface of the pipe wall, so the oil can be heated appropriately and sufficiently without the possibility of coking and decomposition. Good heat transfer without significant resistance.
