Electrolysis polar plate short circuit early warning detection method and device and electrolysis system

Abstract

The invention discloses an electrolysis polar plate short circuit early warning detection method and device and an electrolysis system. The electrolysis polar plate short circuit early warning detection method comprises the steps that voltage between a cathode and an anode of a target electrolytic cell is collected; and a target electrolytic cell short-circuit early warning signal is output if the voltage between the cathode and the anode meets a preset short-circuit early warning condition, wherein the preset short-circuit early warning condition means that the voltage between the cathode and the anode is smaller than a preset short-circuit early warning voltage. According to the electrolysis polar plate short circuit early warning detection method, whether short circuit is possibly about to occur between the cathode and the anode of the electrolytic cell is judged by taking the condition that the voltage between the cathode and the anode is smaller than the preset short-circuit early-warning voltage as the preset short-circuit early-warning condition, and the method is simpler, quicker and more effective, is higher in detection speed, and has the characteristics of simple structure, high reaction speed and easy realization compared with a traditional current and temperature detection-based mode.

Description

technical field [0001] The invention relates to the electronic technical field of automatic monitoring and alarming of short circuit and open circuit between cathode plates during electrolysis, in particular to an early warning detection method, device and electrolysis system of short circuit of electrolytic plates. Background technique [0002] my country is a big non-ferrous metal smelting country in the world, and it is also a big producer of basic metals. According to Jia Mingxing, vice president of the China Nonferrous Metals Industry Association, at a press conference held on January 29 this year, the output of ten non-ferrous metals in my country will be the first in 2020. Breakthrough 60 million tons, reaching 61.68 million tons. However, basic metal smelting consumes a huge amount of electricity, among which the electrolysis production process accounts for the largest proportion of electricity consumption. For example, according to relevant statistics, zinc electroly...

Problems solved by technology

However, the system is expensive, and the detection method is to inspect temperature changes. Due to the temperature rise after the short-circuit fault occurs, there is a certain lag, resulting in slow inspection speed and short-circuit faults cannot be found in time. In addition, this technical solution also detects The detection circuit of this method is very complicated. In the electrolysis workshop of a large-scale production enterprise, the number of plates is huge, and it takes a long time to inspect each plate, and there is also the problem of slow detection speed.
