Device and method for researching oil storage tank tubular heating process heat transfer and flow rules

Abstract

The invention relates to a device and method for researching heat transfer and flow rules in a tubular heating process of an oil storage tank. The device for researching a heat transfer and flow ruleof the oil storage tank in the tubular heating process comprises an experiment storage tank, a rectangular cavity, a PIV device, a data acquisition control system, a heating box and an experiment storage tank; the rectangular cavity is made of the same material and is transparent, the experiment storage tank is arranged in the rectangular cavity, and the space between the rectangular cavity and the experiment storage tank is filled with an experiment medium; a plurality of groups of heating pipes are detachably arranged at the tank bottom; an inlet and an outlet of the storage tank and inletsof the multiple groups of heating pipes are connected with corresponding branch pipelines, and each branch pipeline is provided with a temperature sensor and a flow sensor; the PIV device monitors a three-dimensional temperature field and a three-dimensional speed field of an experimental medium in the experimental storage tank by shooting tracer particles and a temperature developer which are pre-mixed in the experimental medium and shooting the three-dimensional temperature field and the three-dimensional speed field in the experimental storage tank. The heating efficiency of tubular heatingunder different heating conditions can be simulated, and the tubular heating mode is optimized.

Description

Technical field: [0001] The present 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 tubular heating process 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. The winter temperature in northern my country can be as low as -30°C. During the crude oil storage process, the crude oil in the tank will form a gelled structure on the tank roof, 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 product storage. [0003] Tube heating is the main way to heat the oil in the storage tank. At present, the heating ...
