A Visualized Liquid-liquid Two-phase Flow Loop Experimental Device

Abstract

The invention discloses a visualized liquid-liquid diphasic loop experiment device, which is characterized by comprising a liquid storage tank, an outlet valve, a centrifugal pump, a temperature transmitter, a pressure transmitter, a charging system, an acrylic observation pipe segment, an upper inclination pipeline, a backflow system and data acquisition system which constitute a closed experiment loop. The experiment system is designed according to shear stress similar principle and accords with the hydrodynamics dynamic characteristics. The charging system can realize a liquid-liquid original state of any water content; the observation and recording of the flowing characteristics of the oil-water diphasic flow at the horizontal segment, the bended pipe and the upper-layer pipe segment are performed through an acrylic pipe; and the collection and the later period analysis of the related parameters of the experiment process are performed through a data collection system consisting of the temperature transmitter, the pressure transmitter and a pressure difference transmitter at the upper-layer pipe segment. The invention is used for the solar power generating system.

Description

technical field [0001] The invention is an experimental device based on a loop test frame, which can visually observe the experimental phenomenon and flow pattern of liquid-liquid two-phase flow, and collect and analyze parameters such as temperature, flow rate and pressure drop during the test process. Background technique [0002] In today's industrial production, the development of nuclear energy, chemical industry, and petroleum industry has strongly promoted various researches in the field of multiphase flow, and there has been no substantial breakthrough in the research of liquid-liquid two-phase flow. In the actual production of the petroleum industry, processes such as crude oil production with water and oil top water production of refined oil are typical liquid-liquid two-phase flow. Studying the flow law and mechanism of two-phase flow can reduce energy consumption in the production process, reduce internal corrosion of pipelines and promote multi-phase mixed trans...

Problems solved by technology

[0002] In today's industrial production, the development of nuclear energy, chemical industry, and petroleum industry has strongly promoted various researches in the field of multiphase flow, and there has been no substantial breakthrough in the research of liquid-liquid two-phase flow.

The parameters obtained by different materials, pipe diameters, and experimental methods vary widely, and the measured data vary widely, so they cannot be compared with each other.

However, the existing indoor experimental devices are all simple devices that simply realize two-phase contact flow, and cannot simulate the real state of the liquid-liquid two-phase in the pipeline during the actual production process.
