Abstract
The invention relates to a method to automatically control and extinguishing the anode effect of electro-bath by compressed gas. A compressed gas channel is set, and a gas jet device is set on the truss of the aluminum output end of electro-bath and connection to the compressed gas channel. The pressure of the compressed gas is over 0.2mpa, and the content of vapor is lower than 0.01%. Effect detecting and predicting program is stored in automatic control program of the electro-bath and taking judge or predict according to the wave of the electro-bath voltage when anode effect happens. When the electro-bath voltage is lower than the voltage preference, the judge effect would be extinguished, the air valve would be close by electro-bath controlling box instruction executive branch, and the executive branch returns to original state. The advantage is high success ratio of automatically controlling extinguishing effect and can effectively decrease effect coefficient 0.10.
Description
Technical field
The present invention relates to a kind of method of controlling and extinguish the anode effect of electrolyzer with pressurized gas automatically, relate to a kind of production with sodium aluminum fluoride one alumina molten salt electrolysis method in the process of primary aluminum specifically, method with automatic control of pressurized gas and anode effect terminating belongs to the aluminium reduction process production field.
Background technology
Anode effect is to use sodium aluminum fluoride---the alumina molten salt electrolysis method is produced the electrolytic aluminum process, occur in a kind of phenomenon on the anode, when anode effect takes place when, many tiny electric arcs appear on the anode, bath voltage is elevated to tens of volts suddenly, bigger to electrolytic ordinary production and environment damage, therefore in time control and anode effect terminating.
The method of large-scale pre-baked cell anode effect terminating is for using in the wooden stick insertion groove at present; make electrolyzer anode and cathode rare short; thereby reach the purpose of extinguishing effect; this kind method is not only bad for the control anode effect, and workman's danger is bigger during anode effect terminating, and the efficient of extinguishing effect is low; put out the used wooden stick of effect all from the trees seedling; cost is high and big to ecological damage, puts out in the effect process and causes atmospheric pollution big because wooden stick burns, and is unfavorable for environment protection.
Summary of the invention
It is high and little to environmental disruption to the purpose of this invention is to provide a kind of level of automation, can control anode effect effectively, and that saves cost controls and extinguish the method for the anode effect of electrolyzer automatically with pressurized gas.
The objective of the invention is to realize by following technical scheme:
(1) establishes a pipeline at factory building near the electrolysis trough rim is auxilliary, transport pressurized gas;
(2) gas pipeline after gas injection apparatus being installed on the electrolyzer aluminium inlet truss and being compressed links to each other;
(3) compression pressure is more than 0.2mpa, and water vapour content is smaller or equal to 0.01% in the pressurized gas;
(4) in the electrolyzer automatic control program, enroll effect detection and prediction program, effect detection and prediction program are to judge according to the fluctuation of bath voltage whether anode effect takes place, and make during to value when the voltage ratio of setting in bath voltage 〉=effect detection and the prediction program and anode effect take place or be about to generating effect to judge and forecast;
(5) in the electrolyzer automatic control program, enroll effect and utilize time, crust breaking blanking action, extinguish the effect action, judge that at tank control cabinet after electrolyzer comes effect be steering routine, give topworks's crust breaking blanking, extinguish the effect instruction, thereby extinguish effect;
When (6) voltage ratio of enrolling in less than the electrolyzer automatic control program when bath voltage is to value, judge that effect extinguishes, after extinguishing effect, the tank control cabinet command execution unit is closed air-valve, and topworks restores to the original state.
Enroll in the electrolyzer automatic control program in effect detection and the prediction program, the voltage ratio of setting is 8-10V to value, and the effect of enrolling in the electrolyzer automatic control program utilizes the time to be 2-5 minute.
Advantage of the present invention is: effect success ratio height is extinguished in control automatically, can effectively reduce effect coefficient about 0.10, and is little to environmental disruption, saves cost.

Embodiment
Embodiment:
With reference to accompanying drawing, the method for controlling the anode effect of extinguishing electrolyzer with pressurized gas is as follows: (1) near the other auxilliary pressurized gas pipeline of establishing of groove, sets out air-valve 1 on each groove side at cell room.(2) gas injection apparatus (by the solenoid control switch) is installed on electrolyzer aluminium inlet crust breaking head, with compressed gas tube
The road links to each other.(3) compression pressure is more than 0.2mpa, and water vapour content must not be greater than 0.01% in the pressurized gas, pressurized gas one
As adopt inert gas or water-free pressurized air or nitrogen.(4) enroll effect detection and prediction program in the electrolyzer automatic control program, effect detection and prediction program are according to electrolysis
The fluctuation of bath voltage judges whether anode effect takes place, and makes the generation anode effect when bath voltage 〉=8V
Or soon generating effect will be judged and will be forecast.(5) enroll effect in the electrolyzer automatic control program and utilize the time, effect utilizes the time moving for 2-5 minute, crust breaking blanking
Do and extinguish the effect action, judge that at tank control cabinet after electrolyzer comes effect be steering routine, give topworks's crust breaking blanking,
Extinguish the effect instruction, thereby extinguish effect.(6) after extinguishing effect, the tank control cabinet command execution unit is closed airduct, and topworks restores to the original state.
For example: at all pipelines, under the situation that injector and tank control cabinet software all satisfy the requirements, certain electrolyzer comes effect, tank control cabinet detects this groove automatically and comes effect, according to the program of having set, after effect takes place 2 minutes, the blanking of tank control cabinet command execution unit crust breaking, after treating that blanking finishes, tank control cabinet sends instruction, will go out the aluminium head and lay together with gas injection apparatus, and gas injection apparatus enters in the groove near in the aluminium liquid below the anode, tank control cabinet instruction unpack air valve, pressurized gas enters in the groove under certain pressure, makes the boiling of aluminium liquid, after negative electrode and the rare short, effect is put out back, tank control cabinet detects the judgement effect and puts out back, sends and closes valve lift head and jet apparatus, the whole effect end of processing that extinguishes.
