Abstract
The invention discloses a kind of method for reducing electrolytic cell change poles process noise, the method that this method uses three step auxiliary voltages reduces electrolytic cell change poles process noise.Specifically, auxiliary voltage value is set as, the first step and second step auxiliary voltage maximum value are 150mv, and third step auxiliary voltage maximum value is 90mv, and the unit of auxiliary voltage is 10mv.The present invention can solve at this stage change poles process generate voltage instability, occur big metering pin shake noise the phenomenon that, reduce electrolysis energy consumption, improve production and economic benefit.
Description
Technical field
The present invention relates to a kind of methods for reducing change poles process noise, and in particular to a kind of reduction electrolytic cell change poles process is made an uproar
The method of sound.
Background technology
Large-scale pre-baked cell aluminium electrolysis process consumable anode, anode consumption become anode scrap to a certain extent, and anode scrap needs in time more
The anode renewed keeps being normally carried out for electrolysis production.Change poles operation is due to crust breaking, unlimited burner hearth, the heating of new anode, new anode
The reasons such as long packet, cause bath voltage unstable, it may appear that a large amount of needle shakes noise, such as handles not in time, then can influence electricity
Solve production stability.It is increased so as to cause electrolysis energy consumption, efficiency declines, influences production and the economic benefit such as electrolytic environments deterioration.
Invention content
Present invention aims at a kind of method for reducing electrolytic cell change poles process noise is provided, to solve change poles mistake at this stage
Journey generate voltage instability, occur big metering pin shake noise the phenomenon that.
Technical scheme is as follows：Energy required for new pole reaches normal production is calculated according to the carbon quality of new pole
Value, change poles is in the process and change poles terminates the auxiliary voltage of after-applied certain time to electrolytic cell additional heat.Auxiliary voltage uses
The method of three step auxiliary voltages, the auxiliary voltage value are set as：One step and two step auxiliary voltage maximum values are 150mv, three steps
Auxiliary voltage maximum value is 90mv, and the unit of auxiliary voltage is 10mv.Auxiliary voltage keeps time array three times after change poles, maximum
Additional time is 180 minutes, chronomere 20 minutes.
Wherein, the three steps additional electrical platen press refers to carry out electrolytic cell three-stage reality using different auxiliary voltage values
It applies.Preferably, auxiliary voltage value is the first step and second step auxiliary voltage maximum value is 150mv, and voltage range is 0 to 150mv,
Variation unit is 10mv.Third step auxiliary voltage maximum value is 90mv, and voltage range is 0 to 150mv, and variation unit is 10mv.
Auxiliary voltage value implements the time as maximum 180 minutes additional time, chronomere 20 minutes.Always the auxiliary voltage time is maximum
540 minutes.
The present invention can solve at this stage change poles process generate voltage instability, occur big metering pin shake noise the phenomenon that, reduce
Electrolysis energy consumption improves production and economic benefit.
Specific embodiment
With reference to embodiment, the invention will be further described, but not as any limitation of the invention.
Embodiment 1：
By taking 400kA grades of electrolytic cells as an example, a kind of method for reducing electrolytic cell change poles process noise is illustrated, through meter
Calculating the change poles process needs energy 560mVh.
In the embodiment, change poles auxiliary voltage process is as follows：The first step ,+150mV, 60 minutes (1 hour), second step ,+
100mV, 120 minutes (2 hours) third steps ,+50mV, 180 minutes (3 hours)；Electrolytic cell change poles can be greatly decreased in the program
Process noise.
The concrete application example of the above only present invention, the present invention also has other embodiments, all to use equivalent replacement
Or the technical solution that equivalent transformation is formed, it all falls within protection domain of the presently claimed invention.
