Description
Technical field
The utility model belongs to aluminium charcoal element technical field, particularly has the pre-baked anode carbon blocks of two row's venting holes and air discharge duct in a kind of anode carbon block.
Background technology
As everyone knows, industrial aluminum electrolysis bath has two topmost technico-economical comparisones, and one is direct current consumption, and one is current efficiency, and current efficiency has prior meaning in Aluminium Electrolysis.This is because the current efficiency of electrolyzer improves 1%, not only can make output in the situation that do not increase any investment and improve 1%, but also make the direct current consumption of ton aluminium reduce approximately 150kWh left and right.In Aluminium Electrolysis, the reduction of the current efficiency of electrolyzer is the CO due to the metallic aluminium that dissolves in ionogen and the generation of anode basal surface
2The secondary reaction of gas causes, so the raising of current efficiency of aluminium cell can be by reducing CO
2The secondary reaction of gas and aluminium is realized.In order to reach the purpose that improves electrolytic cell currents efficient, can realize by reducing the dissolving of aluminium in ionogen the CO that also can generate by reducing the anode basal surface
2The residence time of gas in ionogen, make CO
2Gas is realized from the method that the anode basal surface is discharged rapidly.
Based on above-mentioned theory, patent 201102606563 has been invented a kind of abnormally-structured aluminium electrolysis cell anode carbon block with vent and preparation method thereof.Industrial aluminum electrolysis bath is quoted this anode carbon block can make anodic gas overflow rapidly from the anode basal surface, thereby reduces the residence time of anodic gas in ionogen, reduces the metallic aluminium and the CO that dissolve in ionogen
2Reaction, thereby be conducive to the raising of electrolytic cell currents efficient.Yet in this patented technology, gas collection hole in anode on venting hole is linear channel of gas collection, adopt this design, when narrower or anode has duct more than two rows in a longitudinal direction when anode, when this channel of gas collection runs into the steel pawl charcoal bowl of anode upper surface, will meet difficulty, just have to and will outwards move at the vent in anode in a row on the longitudinal direction of anode upper surface this moment, its result must cause distance increasing between anode carbon block longitudinal direction two row's venting holes, thereby makes the gas that generates in the middle of anode discharge the distance increase.Patent 20112606563 anode upper and lower venting holes and air discharge duct only have a row on the longitudinal direction of electrolyzer in addition, the charcoal bowl on anode top has eight, become two rows to arrange, 4 of every rows, venting hole and air discharge duct are positioned in the middle of two row's charcoal bowls, cause anode carbon bowl and Anode machining difficulty, and the distance that anodic gas that the anode basal surface produces is overflowed is longer.
Summary of the invention
For the problems referred to above, the utility model patent provides the pre-baked anode carbon blocks that has two row's venting holes and air discharge duct in a kind of anode carbon block, to solve anode carbon block basal surface CO
2The problem that the exhaust distance is larger.This charcoal piece can dwindle anodic gas from the basal surface distance of overflowing, thereby more is conducive to the raising of current efficiency.
The pre-baked anode carbon blocks that has two row's venting holes and air discharge duct in a kind of anode carbon block of the utility model, comprise the anode carbon block matrix, the charcoal bowl, this anode carbon block also is provided with venting hole, the exhaust groove, pneumatic trough, it is 3-4 charcoal bowl that one row amount is wherein arranged on the medullary ray of the upper surface on the length direction of anode carbon block, two pneumatic troughs are arranged in the both sides of charcoal bowl, the bottom vertical of each pneumatic trough is to having the 3-10 venting hole, the bottom of anode carbon block is provided with two exhaust grooves, and the exhaust groove communicates with venting hole.
To be pneumatic trough be provided with several grooves 6 near a side of anodes centre's line to the another kind of structure of this utility model, and venting hole 3 is positioned at the bottom of groove 6.
Described pneumatic trough transverse section is trapezoidal or rectangle, its length is less than the longitudinal direction length of charcoal piece, well width is 30-50mm, be highly 20-40mm, the diameter of venting hole is 25-40mm, the degree of depth in hole is less than the height of anode carbon block, and the distance between Kong Yukong is 80-200mm, and air discharge duct ditch width is 8-25mm
In the Aluminium Electrolysis process, the anodic gas that the anode carbon block basal surface produces is introduced in this groove, then enter each venting hole on its top through this groove, be pooled in the gas collection groove of anode carbon block upper surface through venting hole, then discharge by being located at the metal-made vapor pipe that pneumatic trough top cover plate settles.Reduce heat radiation or in order to reduce metal tube consumption, a metal tube can be set if want, can allow this moment anode surface be positioned at the gas collection groove connection of anode carbon bowl both sides, add between these two gas collection grooves of anode carbon block upper surface one with these two lateral trenches that groove is perpendicular, this groove can be arranged between any two adjacent charcoal bowls of longitudinal arrangement.
The charcoal bowl of the venting hole on the utility model Anodic charcoal piece top and the gas collection groove of upper surface and anode upper surface is to be made by the direct vibratory compaction of weight that is equipped with charcoal bowl, pneumatic trough and vapor pipe corresponding mould in anode vibratory compaction process, and the groove of anode carbon block bottom is anode carbon block green compact machined the making after roasting after above-mentioned vibratory compaction.the exhaust groove of anode carbon block bottom also can be made by following method: when vibratory compaction, basal surface in the moulding box that shakes arranges two and arranges the up-narrow and down-wide steel gusset of anode upper discharge hole on same vertical surface with two, steel gusset mean thickness is 8-50mm, length is identical with anode carbon block length, height deducts the pneumatic trough degree of depth and the charcoal piece upper discharge hole degree of depth sum of anode carbon block upper surface less than the anode carbon block height, form a top after vibratory compaction porose, groove is arranged at the bottom, the middle anode carbon block green compact of sticking with paste body for the carbon element of jolt ramming, then this charcoal block green body is carried out roasting, the machined venting hole of anode carbon block middle and upper part and the linker between the air discharge duct of bottom of removing again after roasting, not only can save widely in this way the amount of finish of mechanical workout charcoal piece bottom groove, and each groove that can form on the anode basal surface is ship type structure, can more be conducive to the discharge of anode basal surface gas like this, and reduction anode consumption.
Have the pre-baked anode carbon blocks of two row's venting holes and air discharge duct in a kind of anode carbon block of the utility model, solved anode carbon block basal surface CO
2The problem that the exhaust distance is larger.This charcoal piece can dwindle anodic gas from the basal surface distance of overflowing, thereby more is conducive to the raising of current efficiency.
