Online monitoring device for anode current distribution of aluminum electrolysis cell and monitoring method of online monitoring device

Abstract

The invention discloses an online monitoring device for anode current distribution of an aluminum electrolysis cell and a monitoring method of the online monitoring device. The online monitoring device is provided with current measuring instruments (2) with a storing function, clamps (3) and an industrial personal computer (12), wherein each clamp (3) is provided with isometric voltage drop measuring points (13) and a temperature sensor (14). The current measuring instruments (2) are packaged in a high-temperature-resistant shielding box and installed on the clamps (3). The clamps (3) are installed on an anode guide rod (1) of the aluminum electrolysis cell in a set mode. The current measuring instruments (2) are connected with the industrial personal computer (12) in a wired mode or in a wireless mode. According to the online monitoring device, currents of all the anode guide rods of the aluminum electrolysis cell can be obtained automatically through the current measuring instruments with the storing function, and finally the anode current distribution variation condition of the aluminum electrolysis cell can be obtained. By means of the online monitoring device and the monitoring method thereof, the problems that in the prior art, labor is wasted, the measurement period is long, it is difficult to reflect the anode current distribution variation in time, the measurement accuracy is not high, and accordingly the control level of electrolysis production is low are solved.

Description

technical field [0001] The invention relates to an aluminum electrolytic cell anode current distribution detection technology, in particular to an aluminum electrolytic cell anode current distribution on-line monitoring device and a monitoring method thereof. Background technique [0002] In the production of aluminum electrolysis, the anode current distribution is an important factor affecting the stable operation of the production. The change of the anode current distribution will cause the change of the current efficiency, the instability of the aluminum liquid level, the change of the groove type, and the effect. Affect the service life of the anode, there will be anode shedding accidents, which will lead to increased energy consumption. Therefore, this requires that in the actual production operation process, the change of anode current distribution can be sensed and mastered in time, and the change trend can be analyzed in order to make adjustments to the production op...
