The short circuit problem between the plates of the electrolytic cell has always been a common fault in the electrolytic smelting industry, which seriously affects the electrolytic efficiency and the grade rate of the smelted metal, and brings great troubles to the production process. In order to solve this problem, onick Optoelectronics launched an infrared thermal imaging electrolytic cell online monitoring system to help enterprises produce.
Application background
In the electrolytic smelting industry, factories generally have hundreds of electrolytic cells, each of which consists of dozens of pairs of positive and negative plates. However, in the actual working process, the positive and negative plates may short-circuit and cannot produce normally, which will not only cause waste of electricity, but also often be accompanied by dangerous situations. The traditional electrolytic cell fault detection method has low accuracy and efficiency for fault detection, and cannot provide enterprises with accurate fault information and the best time for equipment maintenance, which can easily cause large-scale fault shutdown accidents in production enterprises. Using infrared thermal imaging, comprehensive, accurate, real-time, and automatic early warning online monitoring of electrolytic cells can be achieved, which can timely detect equipment failures and repair them, extend the service life of equipment, and ensure the continuous and stable production of enterprises.
Application of infrared thermal imaging in electrolytic cell monitoring
onick photoelectric electrolytic cell infrared thermal imaging online monitoring system determines the specific location of the short circuit between the plates by detecting the plate temperature. The infrared thermal imager is used to collect the infrared thermal image of the electrolytic cell, and the computer processes the infrared thermal image to obtain the pixel points with abnormal temperature. The background analysis software is used to analyze and process the actual fault electrode, that is, the position of the temperature point that is too high, so as to find the position of the plate short circuit fault in the actual detection area for fault resolution. The software setting and connection alarm can also be used to realize real-time alarm of over-temperature.
