Quick electrode short circuit judgment method and system based on temperatures

Abstract

The invention discloses an electrode short circuit detection method and system based on conducting bar temperatures. The method comprises the steps that change of temperatures of a boss which is located on a conducting bar and is in overlap joint with an electrode contact spike is obtained; multiple temperature values within the set time period are obtained; whether the multiple temperature valuesare larger than the set temperature value or not is judged, if yes, it is determined that a short circuit occurs to an electrode in the corresponding position, and if no, the increment, changing along with time, of the multiple temperature values is determined; whether the increment is within the set temperature range or not is judged, if yes, the multiple temperature values are fitted in chronological order through a linear fitting method, and a linear model is obtained; the slope and the determination coefficient of the linear model are obtained; and whether the slope is within the set slope range or not is judged, if yes, whether the determination coefficient is smaller than the set determination coefficient value or not is judged, if no, it is determined that the short circuit occursto the electrode, and the electrode is free of short circuit under other conditions. By adopting the electrode short circuit detection method and system, whether a short circuit occurs to a cathode and an anode or not can be quickly found, after timely treatment, the electrolytic current efficiency and the product quality can be remarkably improved, and the product cost is reduced.

Description

technical field [0001] The invention relates to the field of electrolysis of aqueous solution, in particular to a method and system for quickly judging short circuit of an electrode based on temperature. Background technique [0002] In the industrial production process of electrolytic refining and electrolytic deposition of copper, lead, zinc, nickel, manganese and other metals in aqueous solution, generally a single electrolytic cell contains dozens of anodes and a corresponding number of cathodes, and the anode plates and cathode plates are arranged side by side. The anode and cathode of the electrolytic cell are both plate-shaped, so they are called anode plate and cathode plate, with a single surface area of ​​1m 2 Above, a single electrode plate can pass a current of more than 500A. Due to the narrow space between the cathode and anode plates on the electrolytic cell and the electrode distance of tens of millimeters, local deformation on the electrode surface may caus...
