The invention relates to a single-anode shunting controller used for multi-anode electrobath electrolysis, and a method thereof; the device is an anode unit in an electrobath and comprises an anode bus and a plurality of anode sets which are vertically arranged on the anode bus; each anode set comprises an anode guide rod and an anode carbon block fixed on the anode guide rod; each anode set is independently and movably arranged on the anode but by the anode guide rod; the upper end of each anode guide rod is provided with an anode guide rod controller which is used for regulating the height of each anode guide rode appropriately; the anode bus and the anode guide rods are flexibly connected, and each anode guide rod is provided with an anode current measuring device. The invention changes the passive production process control, actively solves and prevents the current bias produced in electrobath and electrolysis production, automatically guides, controls and balances the production current of the electrobath, balances the heat income of the electrobath, can mostly improve the current efficiency of a single electrobath, protect the anode and the electrobath, make full use of the anode and is very good for promotion and implementation.

Description

1. Technical field: [0001] The invention relates to a single-group anode current regulation technology for multiple groups of anode electrolytic cells in industrial electrolysis production, in particular to a single-anode shunt regulation device and method for multi-anode electrolysis. 2. Background technology: [0002] The current industrial multi-anode electrolyzer electrolytic production adopts computer control and fuzzy control system. In an ideal electrolytic production state, a large amount of gas will not accumulate under the anode, and the electrolyte level is uniform; the anode is inserted into the electrolyte at the same depth of the electrolyte, and the bottom surface is a plane; the production current passes through the anode carbon block evenly in each group of anodes, and enters the Electrolyte; the current density distribution in the anode, electrolyte, aluminum liquid and cathode carbon block group is uniform, the electrolysis production runs smoothly, and th...

Problems solved by technology

These are reactive remedies that do not proactively address some of the anode bias currents that occur in electrolytic production and the problems it causes

[0005] Because the electrolysis effect is often caused, without using a reactor, the electrolysis production current is high and sometimes low, and it is difficult to implement effective control. In order to stabilize the electrolysis production current, many aluminum electrolysis manufacturers use saturated reactors to adjust and stabilize the electrolysis production current. , but while the saturable reactor regulates and stabilizes the electrolytic production current, it consumes a large amount of active and reactive power, which reduces the utilization rate of electrolytic production.

At the same time, it also causes the power factor of the power network to decrease

[0006] Anode bias current leads to various effects in electrolytic production, which not only consumes energy, consumes anodes, reduces electrolytic efficiency, or even damages electrolytic cells and electrolytic equipment, resulting in unreasonable, normal, safe and economical production of electrolytic cells.
