Description
Technical Field
The invention belongs to the field of pipeline fluid conveying, and particularly relates to a device and a method for on-line monitoring of scaling and blocking trend of an inner wall of a metal pipe.
Background
In various industrial fields such as metallurgy, petrochemical industry, and chemical industry, there are a large number of processes for transporting liquid or slurry-like fluid substances (hereinafter referred to as "fluids") by using pipelines. The components of the fluid in the pipeline are complex, and the fluid is formed by mixing various acid/alkali/salt solutions, particle suspension materials, molten slurry, various mineral substances and the like in different processes, and has various working conditions of low temperature, normal temperature, high temperature and the like.
The length of the conveying pipeline is possible from a few meters to tens of kilometers, the pipeline is provided with a plurality of structures such as a single pipe, a calandria, a bending rotation structure and the like, and also has a sleeve structure for long-distance heat preservation and heating, the inner pipe conveys fluid, the outer pipe is filled with steam or heat-conducting fluid, and the outer pipe is wrapped with heat preservation and heat insulation materials.
The fluid in the pipe can generate more or less chemical reaction in the conveying process, and a layer of scale is gradually deposited on the inner wall of the pipeline, just like scale is generated after the kettle is used for a long time. The scale in the pipe gradually thickens, so that the inner space of the pipe is squeezed and narrowed, and the transportation of fluid in the pipe is blocked until the pipe is plugged, thereby seriously affecting the normal operation of the process. Once the pipeline is blocked, particularly a long-distance pipeline, the specific blocking position is difficult to judge, and the pipeline can be only detached and checked in a segmented and partitioned manner and dredged or replaced, so that the long-time production stopping, overhauling and maintenance workload of the whole process is huge.
For example, the core process in the alumina production factory of the aluminum smelting industry is high-temperature pipeline digestion, namely, a sleeve with the total length of more than ten kilometers is in a multi-turn bent structure, the inner tube is used for conveying slurry-like fluid composed of substances such as aluminum silicon mineral powder, naOH, ca (OH) 2 solution and the like, the outer tube is filled with steam with the temperature of more than 230 ℃, and the inner tube fluid is continuously heated. The inner tube fluid is subjected to chemical reaction in the conveying process and in a high-temperature environment, and finally Al (OH) 3 and red mud ore pulp with residual silicon and calcium substances are generated by dissolution. In the alumina pipeline digestion process, the scaling and blocking phenomenon of the inner pipe wall easily occurs in a large number of pipelines, and according to practical production experience, the new pipeline generally generates serious scaling for several months, so that the flow velocity and flow of the fluid in the pipeline are reduced, and even the pipeline is blocked and blocked. At present, an alumina plant can only adopt a mode of regular production stopping and maintenance for about 3 months, the whole pipeline is flushed by high-pressure water, scaling in the pipeline is flushed out by flushing, and a pipeline can only be disassembled in a segmented way to find a blocking point for dredging or replacement when the pipeline is seriously blocked. The method has long production stopping time, low water and energy consumption, low overhaul and maintenance efficiency, huge workload, and great manpower and material resources consumed for each maintenance.

step S2, the micro resistance measuring instrument (1) measures resistance values of the wheel tour loops one by one through an internal controller of the wheel tour controller (2), and sends measured data to a resistance value record analysis data server (4) through the field network communication equipment (5);
and S3, analyzing the resistance value data in the resistance value record analysis data server (4) through a trend model operation display and alarm interface software (6) to generate a chart, and sending out early warning information when the resistance value exceeds a set value.
7. The method for on-line monitoring of the scaling and plugging tendency of the inner wall of a metal pipe according to claim 6, wherein: in the step S3, each section of metal pipe is fitted into a curve along a time axis according to the accumulated scale thickness parameters of the periodic time sequence, so as to form the real-time variation trend of the scale thickness.
8. The method for on-line monitoring of the scaling and plugging tendency of the inner wall of a metal pipe according to claim 6, wherein: the trend model operation display and alarm interface software (6) is used for customizing and developing various display models and alarm measures according to different users and process requirements, and developing functions of user login, authorized control and historical record inquiry.
