Description

A kind of special-shaped multicell carbon anode
Technical field
The invention belongs to used for aluminium electrolysis carbon anode technical field, relate in particular to the carbon anode that there are a plurality of chambers a kind of side.
Background technology
Carbon anode is electrolyzer " heart "; Can carbon anode up to standardly have fundamental influence for the electrolysis parameters; Effect aspect energy-saving and cost-reducing is particularly evident, as: carbon anode is in participating in electrolytic process, and the anodic bottom can produce a large amount of CO 2Gas, if employed carbon anode is the anode that does not have chamber, then the major part in these gases is difficult to overflow; Thereby accumulate in the anodic bottom; When these gases accumulate to certain degree, then can form bubble layer at the anode bottom, bubble layer can not conduct electricity; Thereby increase resistance, power consumption also increases along with the increase of resistance.For this reason, the fluting anode has just appearred.The patent No. is that the patent of ZL200520200777.9 discloses a kind of fluting anode, and in this technical scheme, groove is vertically perhaps laterally; The groove degree of depth vertically is 150mm-400mm, and the deficiency that this technical scheme exists is: if groove is shallow, especially when groove has only 150mm; The action time of reducing bubble layer thickness is too short; Less than 1/3 of anodic cycle, if the ditch groove depth, especially when groove would reach 400mm; The anode insufficient strength is easy to the cracked piece that falls in electrolytic process; Application number is to disclose a kind of fluting anode technology in 201020194121.1 the patent application document; Two terminations of anodic described in this application file or end face have the up/down perforation groove; The weak point of this technical scheme is: groove is opened at end face; Be unfavorable for anode bottom intermediate exhaust, because the gas that anode is produced in participating in electrolytic process mainly is distributed in anode bottom middle part, the abundance of two ends gas is less; Open after the through slot, influenced anodic intensity, in electrolytic process, occur the anode fragmentation easily and fall piece.
In sum, there are defectives such as exhaust is not smooth, anode bottom bubble pressure drop height, insufficient strength in existing anode technology.
Summary of the invention
Technical problem to be solved by this invention provides the carbon anode that a kind of exhaust is unobstructed, the pressure drop of anode bottom bubble is low, anode intensity is high.
In order to address the above problem, technical scheme provided by the present invention is:
A kind of special-shaped multicell carbon anode has groove along anode bottom width, and the top of groove region intermediate is A to the vertical range of anode bottom 1, A 2A n, the top of groove two end regions is B to the distance of anode bottom 1, B 1B n, A n<B n
Preferably, said groove is non-connectivity slot.
Preferably, the said groove opening that is positioned at anode sides diminishes to the direction of distance along the anode bottom to anode top of groove top gradually.
Preferably, the top of said groove includes plane, curved surface.
Preferably, groove top is 1mm-300mm to the distance of anode sides, and groove top is 1mm-500mm to the distance of anode bottom surface, and the wide of groove is 1mm-50mm, and groove top is 5mm-590mm to anode charcoal bowl bottom distance.
Need be in this explanation be the confining method of groove region intermediate described in the present invention and groove two end regions.Region intermediate here and two end regions are relative notions, and its confining method is: with reference to figure 4, be example with the sectional view of groove; With line segment a, b groove is divided into any three sections, is labeled as I respectively, II; III, wherein II is a region intermediate, I, III are two end regions.As aforesaid A n<B nThe time, anodic intensity promptly obviously increases, and reduces even avoids anode to occur breaking piece in the course of the work, compares with prior art, has significant effect.
Beneficial effect of the present invention is: increased anodic intensity 1..Although the bubble that anode is produced at work mainly concentrates on the anodic bottom; But,, then can reduce anodic intensity if directly laterally or vertically slot on anodic bottom edge according to prior art; In industrial production, very easily cause the piece accident of breaking, lose more than gain.According to technology provided by the present invention, two end regions of groove can realize smoothly that exhaust, region intermediate play the effect of reinforcing anode intensity, can obtain beyond thought effect; 2. significantly reduce the bubble pressure drop of anode bottom.The groove of being opened among the present invention directly leads to the most concentrated zone of anode bottom bubble; Can timely and effective discharging anode bottom bubble, compare with the existing anode of not slotting, can significantly reduce pressure drop 10~50mV; Compare with the existing anode of opening straight trough, can reduce pressure drop 5~40mV.
