Abstract
The invention discloses a nitrogen blanking effect for quenching anode in the production of electrolyzing aluminium, which is characterized by the following: making nitrogen pass through preheated steel pipe; getting through anode bottom-hand; passing through air current stirring aluminum water and electrolyte; destroying a layer of unspace gas film which forms on anode surface; escaping gas; achieving blanking effect. The method possesses the advantages of economic, environment protection and safety, which adapts for all prebaked-anode electrolyzing aluminum manufacturers.
Description
One, technical field
The present invention relates to a kind of novel method of anode effect terminating in the Aluminum Electrolysis Production.
Two, background technology
Anode effect takes place main because electrolysis bubble is assembled at anode surface, is difficult for overflowing, and the gas membrane until form one deck zero-clearance at anode surface raises voltage, produces spark discharge, so anode effect takes place; Traditional effect method of putting out is to put in the anode bottom with timber, ionogen is stirred in the burning that utilizes timber, thereby aluminium liquid reaches the purpose of putting out back effect, but this method exist cost height, dangerous, labour intensity greatly, shortcomings such as material flies upward seriously, contaminate environment and aluminium liquid.
Three, summary of the invention
The root problem that the present invention solves is: by using method for extinguishing anode effect by means of nitrogen, further improve anode effect terminating efficient, reduce a large amount of power consumption in the effect process, reduce labour intensity, reduce environmental pollution, improve safety performance.
The character of nitrogen is more stable,, be the most stable in the known diatomics very, under the electrolysis of aluminum condition, do not react with aluminium liquid and ionogen near rare gas element, nitrogen purge aluminium liquid also commonly used in industrial production is analyzed in theory and can be extinguished effect with nitrogen fully simultaneously.As the byproduct that produces in the oxygen preparation, we can obtain cheap nitrogen, abundant amount, and it is fully feasible therefore extinguishing effect with the alternative timber of nitrogen.
Processing method of the present invention is such: will be by nitrogengas cylinder, tensimeter, oxygen belt, control valve, put out the means for influencing that puts out that the effect steel pipe forms and move on the electrolyzer that needs operation, and the effect steel pipe is put out in preheating; Open electrolyzer termination cover plate, manually crust breaking blanking; After putting out the effect condition maturity, slowly open by-pass valve control, make and put out effect steel pipe tapping and have a small amount of gas to discharge, the steel pipe that preheating is good puts in the anode bottom from the centre joint, adjust gas velocity, to contact and don't produce big ups and downs with the anode bottom be good so that aluminium liquid stirs; Extinguish the steel pipe that to move around in the process of effect.When being difficult to extinguish, effect can operate simultaneously at the electrolyzer two ends; Effect is extinguished the back and is adjusted tolerance earlier, closes gas check valve, the site clearing behind the taking-up steel pipe.
Positively effect of the present invention is: technology is simple, and is easy to operate, can reach the requirement of anode effect terminating fully; Compare with traditional effect method of putting out, will reduce production costs greatly, reduce labour intensity, reduce environmental pollution, improve safety performance.
Four, description of drawings
Fig. 1 is the application synoptic diagram of technology of the present invention.
Five, embodiment
As shown in drawings, the means for influencing that puts out that assembles is transported on the electrolyzer 9 that needs operation by unwheeling, requires nitrogengas cylinder 10 tensimeters 1 value to be not less than 0.3Mpa; Put out effect steel pipe 5 port closeds, effect steel pipe 5 is put out in head perforate, preheating; Open electrolyzer termination cover plate, manually crust breaking blanking; After putting out the effect condition maturity, slowly open by-pass valve control 4, air communication is crossed reducing valve 2 oxygen belts 3 backs and is discharged from putting out effect steel pipe 5 tappings, the effect steel pipe 5 that puts out that preheating is good puts in anode 6 bottoms from the centre joint, adjust gas velocity, stirring aluminium liquid 8 and ionogen 7, is good so that aluminium liquid 8 stirs the contact of anode 6 bottoms and don't produces big ups and downs; The process of the extinguishing effect steel pipe 5 that can move around.When being difficult to extinguish, effect can operate simultaneously at the electrolyzer two ends; Effect is extinguished the back and is adjusted tolerance by by-pass valve control 4 earlier, takes out steel pipe 5 backs and closes gas check valve 4, site clearing.
Claims (1)
1, method for extinguishing anode effect by means of nitrogen, it is characterized in that: will be by nitrogengas cylinder (10), tensimeter (1), reducing valve (2), oxygen belt (3), control valve (4), put out putting out on the electrolyzer that means for influencing moves to needs operation (9) that effect steel pipe (5) forms, effect steel pipe (5) is put out in preheating; Open electrolyzer (9) termination cover plate, manually crust breaking blanking; After extinguishing the effect condition maturity, slowly open by-pass valve control (4), make the perforate of putting out effect steel pipe (5) head have a small amount of gas to discharge, the steel pipe that preheating is good puts in the anode bottom from the centre joint, adjust gas velocity, to contact and don't produce big ups and downs with the anode bottom be good so that aluminium liquid stirs; Extinguish the steel pipe that to move around in the process of effect.
