Loop-type multi-phase flow erosion test device

Abstract

The present invention discloses a ring-road type multi-phase flow erosion tester comprising a gas, oil and water three-phase separation tank and pipe circulating systems of said three phases including, in detail, a gassy system ranging from an export at the top part of the three-phase separation tank, a cooler and a cyclone separator, a circulating gas screw compressor to the pipe filter; an oil phase system ranging from an export at the middle part of the three-phase separation tank, a diesel magnetic drive pump, a heater to the pipe filter; and a water phase system ranging from an export at the bottom part of the three-phase separation tank, a wastewater metering pump, a heater to the pipe filter. After mixing, the three phases are connected to the three-phase separation tank through the pipe filter and a testing platform for pieced to be tested. The present invention is capable of simulating erosion study cases in practical pipe fittings such as tee joints, bend pipes, transition pipes and liner pipes to perform a transient characteristics prediction study of gas, oil and water multi-phase flow erosion destruction.

Description

technical field [0001] The invention relates to an erosion test device, in particular to a ring type multiphase flow erosion test device. Background technique [0002] Fluid pipeline is a special equipment for conveying fluid under certain temperature and pressure conditions. With the development of economy and technology, people pay more and more attention to the role of pipeline in transportation. Now it has become one of the five major transportation methods alongside highway, railway, water transportation and aviation, and is widely used in west-east gas transmission, urban Fluid transportation and system engineering such as gas pipeline network and petrochemical equipment. [0003] In recent years, in the field of petrochemical industry, with the increasing processing proportion of heavy and sulfur-containing crude oil, the erosion failure of pipelines and tube bundle equipment (heat exchangers, air coolers, etc.) in the petrochemical industry is more common, such as: ...

AI Technical Summary

Problems solved by technology

[0006] (1) The erosion failure of industrial pipelines in actual engineering applications is often the result of the coupling of corrosion and multiphase flow, but most of the existing test devices can only simulate the erosion corrosion process under single-phase flow conditions, and it is difficult Research on Erosion Failure of Industrial Pipelines

[0007] (2) The conventional test method usually tests the erosion rate by weighing and measuring the thickness, which cannot realize the transient characteristics of the critical value of industrial pipeline erosion damage

[0008] (3) At present, the research on the mechanism of erosion test in my country is not deep enough, the test method of related equipment is far from the actual working conditions, and the experimental results are difficult to promote engineering applications
