An early warning method and detection device for electrolyzer plate failure

Abstract

The invention provides a pre-warning method and a detection device for electrolytic cell pole plate faults. The pre-warning method comprises the following steps of: S1, obtaining an infrared thermal image and position information of an electrolytic cell pole plate, and extracting temperature information of a pixel area corresponding to the pole plate; S2, calculating a confidence interval of a pole plate temperature according to the temperature information, and confirming that the pole plate temperature is in the confidence interval; S3, constructing a grey prediction model for predicting poleplate temperature change on the basis of a history temperature data sequence of the pole plate; and S4, carrying out fuzzing analysis on a temperature change amount and a change rate of the pole plate on the basis of the grey prediction model and the position information, so as to pre-warning pole plate faults. The detection device comprises an infrared imager, wherein the infrared imager is usedfor obtaining the infrared thermal image of the electrolytic cell pole plate; and the infrared thermal imager is connected with a processing module which is used for processing the infrared thermal image. According to the pre-warning method and the detection device, the correctness and efficiency of detecting and pre-warning pole plate faults can be effectively improved.

Description

technical field [0001] The invention relates to fault monitoring technology, and more specifically, to an early warning method and detection device for electrolyzer plate faults. Background technique [0002] In the copper smelting process, blister copper containing 99.5% copper is pre-made into a thick plate as an anode, and thin sheets made of pure copper or stainless steel are used as a cathode. A solution of sulfuric acid and copper sulfate with a fixed ratio is used as the electrolyte. In order to maintain the temperature of the electrolyte and prevent the acid from evaporating, cloth is covered on the tank surface of the working tank, and workers can randomly lift it when managing the tank surface. Under this condition, the anode in the tank dissolves, the anode copper enters the electrolyte in the form of ions, diffuses to the cathode, and obtains electron precipitation at the cathode; at the same time, the anode impurities dissolve in the electrolyte in the form of ...
