Abstract
Locally stretched one's legs the invention discloses a kind of large scale electrolytic cell restarting the method for light maintenance, and in particular to a kind of method for carrying out light maintenance of locally being stretched one's legs electrolytic cell during large scale electrolytic cell restarting.Technical problems to be solved are costly when being carried out large repairs at present to electrolytic cell, and the equipment startup time is longer, wastes the working time, and operating efficiency is low.The present invention comprises the following steps：1st, clear up stopping the electrolytic cell after groove；2nd, the serious carborundum side wall carbon block of the upper weathering of stretching one's legs to electrolytic cell periphery is changed after cleaning out；3rd, preheated coal tar is sent forth on the stretching one's legs of electrolytic cell periphery, 4, with the periphery paste heated carries out local light maintenance to sending stretching one's legs for coal tar forth, meet to start requirement so as to reach.Using the present invention after such method, overhaul cost is reduced, reduces startup risk, shortens and starts the time, improve operating efficiency.
Description
Technical field
The present invention relates to a kind of electrolytic cell, and in particular to electrolytic cell is locally stretched one's legs during a kind of large scale electrolytic cell restarting
The method for carrying out light maintenance.
Background technology
Electrolytic cell is in normal productive process, because certain cause specific causes electrolytic cell is improper to stop groove, current electrolysis
Groove is improper stop groove after equipment is overhauled, meet when electrolytic cell is again started up requiring to carry out restarting electrolytic cell, and
Stretching one's legs for electrolytic cell is not repaired；The finishing stretched one's legs to electrolytic cell is all that electrolytic cell is stopped when electrolytic cell needs overhaul
Groove is repaired, and needs during overhaul all to lay refractory brick, insulating brick, cathode carbon pieces etc. in electrolytic cell again, every electrolytic cell is big
Repairing expense about needs 1,400,000 or so, costly, needs to restart equipment after overhaul, and it is longer and big every time to start the time
Repair and waste the working time, cause operating efficiency low.
The content of the invention
The technical problem to be solved in the present invention be it is costly when being carried out large repairs at present to electrolytic cell, equipment start the time compared with
It is long, the working time is wasted, operating efficiency is low, there is provided it is a kind of simple to operate, overhaul number is reduced, reduces overhaul cost, is reduced
The large scale electrolytic cell restarting of the number of starts of electrolytic cell is locally stretched one's legs the method for light maintenance.
To achieve the above object, the present invention uses following technical proposals：A kind of large scale electrolytic cell restarting is locally stretched one's legs
The method of light maintenance, comprises the following steps：1st, clear up stopping the electrolytic cell after groove；2nd, to electrolytic cell periphery after cleaning out
The serious carborundum side wall carbon block of upper weathering of stretching one's legs is changed；3rd, preheated coal tar is sent forth on the stretching one's legs of electrolytic cell periphery
Oil, 4, with heat periphery paste carries out local light maintenance to sending stretching one's legs for coal tar forth, so as to reach meet start requirement.
The described cleaning to electrolytic cell includes the cleaning that aluminium is stayed to the electrolyte in stopped groove, bottom land, to furnace bottom negative electrode
Carbon block and groove surrounding are stretched one's legs the cleaning of upper carborundum, the secondary cleaning to weak part of stretching one's legs.
Using the present invention after the above method, when meeting that electrolytic cell is again started up requiring, according to stopped groove actual conditions
The part of weak part of stretching one's legs electrolytic cell is stretched one's legs and carries out light maintenance, is reduced overhaul cost, is reduced startup risk, is shortened when starting
Between, improve operating efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of electrolytic cell.
Fig. 2 is that electrolytic cell is stretched one's legs the partial structural diagram before light maintenance.
Fig. 3 is that electrolytic cell is stretched one's legs the partial structural diagram after light maintenance.
Embodiment
As shown in Figure 1 to Figure 3, the present invention comprises the following steps：1st, clear up stopping the electrolytic cell 1 after groove；2nd, clear up
The serious carborundum side wall carbon block of weathering on 2 of stretching one's legs on electrolytic cell periphery is changed after clean；3rd, on electrolytic cell periphery
Send preheated coal tar on stretching one's legs forth, 4, with the periphery paste heated carry out local light maintenance to sending stretching one's legs for coal tar forth,
Required so as to reach to meet to start.
The described cleaning to electrolytic cell includes the cleaning that aluminium carbon cathode blocks are stayed to the electrolyte in stopped groove, bottom land 3,
Furnace bottom cathode carbon pieces and groove surrounding are stretched one's legs the cleaning of upper carborundum, the secondary cleaning to weak part of stretching one's legs.
Electrolytic cell is in normal productive process, and when certain cause specific causes that electrolytic cell is improper to stop groove, equipment is carried out
Maintenance, meet to carry out electrolytic cell when electrolytic cell is again started up requiring light maintenance, light maintenance carries out secondary open to electrolytic cell again after terminating
It is dynamic, overhaul number is reduced, reduces startup risk, shortens and starts the time, improve operating efficiency.
Claims (1)
- A kind of method of light maintenance 1. large scale electrolytic cell restarting is locally stretched one's legs, it is characterised in that:Comprise the following steps：1st, it is right Stop the electrolytic cell after groove (1) to be cleared up；2nd, the serious carborundum side of the upper weathering of stretching one's legs to electrolytic cell periphery after cleaning out Portion's carbon block is changed；3rd, preheated coal tar is sent forth on the stretching one's legs of electrolytic cell periphery (2), 4, with the periphery heated Paste and carry out local light maintenance to sending stretching one's legs for coal tar forth, required so as to reach to meet to start；The described cleaning to electrolytic cell Cleaning including staying aluminium to the electrolyte in stopped groove, bottom land (3), upper carborundum that furnace bottom cathode carbon pieces and groove surrounding are stretched one's legs Cleaning, the secondary cleaning to weak part of stretching one's legs.
