Problems solved by technology
[0003] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional digital oxide accumulation detection device, which can directly give the oxide risk assessment level, save a lot of detection time, improve accuracy, and greatly reduce the risk of oxide accumulation. The possibility of another tube explosion caused by the accumulation saves huge expenses for the power plant, and solves the problem that the oxide accumulation inside the tube cannot be accurately given. The oxide accumulation must be determined based on relevant experience and on-site X-ray inspection. , which brings huge loss of time and economy to the power plant

The invention discloses a three-dimensional digital oxide accumulation detection device, and belongs to the technical field of oxide accumulation detection. The device comprises a heating surface pipe and a detection mechanism, the detection mechanism comprises an electromagnetic probe, and L-shaped fixing strips are fixedly connected to the front side and the rear side of the heating surface pipe; an L-shaped sliding groove is formed in the side, away from the heating surface pipe, of the L-shaped fixing strip, and two fixing blocks are fixedly connected to the top of the electromagnetic probe. The oxide in the heating surface pipe is detected through the electromagnetic probe, a magnetic field intensity electric signal is obtained, then the electric signal is wirelessly transmitted to the display, a three-dimensional distribution diagram of oxide accumulation in the pipe is visually displayed through the image processor on the display, and the oxide risk assessment level is directly given. X-ray detection and experience confirmation are not needed, so that a large amount of detection time is saved, and the accuracy is improved.
Description
technical field [0001] The invention belongs to the technical field of oxide accumulation detection, in particular to a three-dimensional digital oxide accumulation detection device. Background technique [0002] When the oxide accumulation non-destructive detector is used to detect the oxide accumulation inside the heating surface tube, only the maximum output signal, that is, the maximum accumulation inside the heating surface tube, is used as the basis for whether to deal with it. In other words, only It is not accurate and scientific to judge whether the oxide clogged area meets the treatment standard based on the accumulation amount in one point or a small range, because the accumulation amount in one point or a small range exceeds the standard, and it cannot fully reflect the oxides in the whole pipe. It is easy to cause misjudgment and misjudgment under normal circumstances; secondly, due to the magnetic flux leakage phenomenon in the austenitic tube, the existing oxi...
