Abstract

The present invention relates to a device and method for studying the heat transfer and flow law of the tubular heating process of the oil storage tank, wherein the device for studying the heat transfer and flow law of the tubular heating process of the oil storage tank includes an experimental storage tank, a rectangular cavity, and a PIV device , data acquisition control system, heating box, experimental storage tank, and rectangular cavity are of the same material and transparent, the experimental storage tank is placed in the rectangular cavity, and the experimental medium is filled between the rectangular cavity and the experimental storage tank; the bottom of the tank is detachably equipped with multiple A set of heating tubes; the inlet and outlet of the storage tank and the inlets of multiple heating tubes are connected to the corresponding branch pipelines, and each branch pipeline has a temperature sensor and a flow sensor; the PIV device shoots the tracer particles and temperature developer mixed in the experimental medium , shoot the three-dimensional temperature field and velocity field in the experimental storage tank, and monitor the three-dimensional temperature field and three-dimensional velocity field of the experimental medium in the experimental storage tank. The invention can simulate the heating efficiency of tube heating under different heating conditions, and optimize the tube heating mode.

Description

Technical field: [0001] The invention relates to the technical field of research on heat transfer and flow laws in storage tanks using tubular heating to store crude oil or refined oil, and specifically relates to a device and method for studying heat transfer and flow laws in the process of tubular heating of oil storage tanks . Background technique: [0002] As my country's demand for crude oil continues to increase, my country's crude oil reserves continue to increase. In northern my country, the temperature in winter can be as low as -30°C. During the crude oil storage process, the crude oil in the tank will form a gel structure on the tank top, tank wall and tank bottom due to wax precipitation. In order to ensure the normal operation of sending and receiving oil, heating the crude oil in the storage tank is a necessary means in the process of oil storage. [0003] Tubular heating is the main way to heat the oil in the storage tank. At present, the heating pipes are ...
