A portable instant superheat measuring instrument for electrolytic aluminum has been developed successfully

    Recently, a kind of electrolytic aluminum energy saving artifact called portable pre-tank superheat real-time measuring instrument has been developed successfully.The measuring instrument is developed by Beijing Core Power Technology Co., Ltd. on the basis of the original crystal temperature measuring equipment after many years of efforts. It is suitable for the on-line measuring equipment used before electrolytic cell.The device changes the former industry no instant, convenient, fast, low cost, easy to use before electrolyzer of heat measuring equipment, to make simple measuring electrolyte "3 c" (at the beginning of the electrolyte temperature, crystalline temperature and degree of superheat), only a handheld devices to keep electrolysis plant cost nearly ten million yuan a year, create greater economic benefits for the enterprise.

    In the process of electrolytic aluminum production, the superheat is an important parameter to measure the state of electrolytic cell, and the superheat is the difference between the temperature of electrolytic cell and the temperature of primary crystal, which is the initial crystallization temperature of electrolyte.In the process of electrolytic aluminum production, the low superheat will affect the flow of electrolytes, while the high superheat will increase energy consumption. It is very important for electrolytic aluminum to grasp the superheat of a single cell immediately.Therefore, the superheat is the key parameter for the refinement control of electrolytic aluminum cell, which is of great significance for enterprises to save energy and reduce consumption, reduce cost and improve market competitiveness.

    In the production cost of electrolytic aluminum, the electricity cost accounts for about half of the cost, controlling the superheat at about 10 KWH is the best state of power consumption in the process of electrolytic aluminum production.At present, the control level of superheat in electrolytic aluminum industry is uneven. Since there is no effective daily measurement method before, in the electrolytic production process, it mainly relies on artificial experience to judge whether the superheat is appropriate. Therefore, the superheat in the production of some enterprises is above 20℃, even more than 40℃.And every reduce superheat 5℃, can improve current efficiency 3%~4%, save energy 2%, tons of aluminum saving electricity dozens of yuan.

    Beijing core power company before production of the portable tank of heat meter using multi-sensor measurements, through a variety of algorithms and digital filter anti-jamming technology, data modeling, and similarity ratio, to measure the crystal temperature at the beginning of feature points (crystal temperature at the beginning), measuring the electrolyte temperature had been (tank temperature) and the calculation of the heat.The measuring instrument USES wireless data connection mode to avoid the situation that the common connection mode is unreliable in the electrolysis field. Industrial handheld computer is adopted to enable the measuring instrument to record and save the measurement data in real time, and the historical data can be exported, so as to facilitate the establishment of the trough temperature management database for each enterprise.At the same time, the measuring instrument also has scanning (TWO-DIMENSIONAL code or bar code) slot number identification, online upgrade and online diagnosis and other functions, and can be further expanded according to use requirements.In addition, the use process of portable pre-bath superheat real-time measuring instrument is as simple as that of measuring the temperature of electrolytic cell. Its measuring probe can be used repeatedly, and its structure is similar to that of ordinary temperature measuring thermocouple, measuring less than 2 minutes at a time, which is not only a good helper in the production of electrolytic aluminum, but also brings huge space for enterprises to save energy and reduce consumption.
