Device and method for simulating heat transfer and flow law during hot oil spraying and heating in oil storage tank

Abstract

The invention relates to a device and method for simulating heat transfer and flow laws during the heating process of hot oil spraying in an oil storage tank, wherein the device and method for simulating heat transfer and flow laws during the heating process of hot oil spraying in an oil storage tank include: an experimental storage tank, a rectangular cavity, and particles Image speed measurement device, data acquisition control system, heating device, experimental storage tank and rectangular cavity are of the same material and transparent, the experimental storage tank is set in the rectangular cavity, and the experimental medium is filled between the rectangular cavity and the experimental storage tank; A group of heating coils, multiple interfaces are arranged at equal intervals on the heating tube, and the interface is detachably connected to the nozzle; by switching the valve, switching the experimental process, and constructing different experimental conditions; Tracer particles and temperature dyes to obtain data on the flow and temperature distribution of media in experimental tanks. The invention realizes the visualization of its flow field and temperature field by constructing a crude oil storage tank capable of simulating the hot oil spraying heating process.

Description

Technical field: [0001] The present invention relates to the technical field of research on heat transfer and flow law in storage tanks for storing crude oil or refined oil using hot oil spray heating process, and specifically relates to heat transfer and flow law simulation of oil storage tank hot oil spray heating process Devices and methods. Background technique: [0002] According to the "National Petroleum Reserve Medium and Long-Term Plan", before 2020, my country plans to form a total reserve size equivalent to 100 days of net oil imports. However, according to various estimates, my country's current crude oil reserves are still only equivalent to less than 40 days of net oil imports. In the face of the current international oil price situation, my country must further expand its strategic oil reserves, and at the same time actively develop the reserves of private enterprises and society. With the increase of crude oil storage, more and more attention has been paid to...
