Oil tank heaters are divided into two types of tank fast heaters, segmented heaters, and coiled tube heaters according to different structures.
Oil tank local fast heater working principle:
1. Extend the "vortex hot film heat exchanger" into the bottom of the oil tank along the radial direction of the storage tank. The heat medium (steam) goes through the tube. The oil flows from the inner tube of the shell and the oil suction port of the shell directly connects to the tank medium.
2. A temperature control valve is set at the steam inlet of the heat exchanger, and the steam inlet volume of the steam inlet of the heat exchanger is controlled by the temperature detection of the oil product outlet temperature to ensure the constant oil temperature.
The heat exchanger uses a high-efficiency heat exchange element, a vortex heat film tube, to maintain a reasonable flow of oil between the tubes. The thermal efficiency is 3-5 times that of the ordinary heat exchanger. Its enhanced heat transfer mechanism is: oil fluid flows on the inner and outer surfaces. It is designed to be a turbulent flow, which produces strong shock and scouring effects. The direction of flow is constantly changing. High-temperature oil fluids that are close to the tube wall surface are constantly replaced, the thermal insulation layer is thinned and even destroyed, and the heat transfer on the metal surface is accelerated. The micro vortex is strengthened, which strengthens the heat diffusion inside the oil fluid. The fluid close to the surface of the pipe wall will not cause local high temperatures and overheating so that the oil can be properly and adequately heated without the possibility of coking and decomposition. It has good heat transfer and does not have much resistance.
