Abstract
The utility model discloses a 700kA-grade electrolytic bath which comprises feeding points (3). 64 anodes (1) of the 700kA-grade electrolytic bath are parallel or perpendicular to the length direction of the electrolytic bath and are provided with 8 gaps (2) along the length direction, 2-3 feeding points (3) are arranged in each gap (2), and the width of each gap (2) ranges from 100mm to 250mm. Concentration difference of aluminum oxide at anode bottoms can be decreased, the critical electrode distance of the 700kA-grade electrolytic bath can be shortened, and energy is saved.
Description
Technical field
The utility model relates to the blanking point of a kind of electrolyzer, particularly electrolyzer.
Background technology
700kA level electrolyzer is the large capacity electrolyzer of future development, because of its long anode dimension, cause that aluminum oxide and aluminum fluoride concentration there are differences between pole span, cause electrolyte conductivity to cross big-difference and make distribution of current unstable, limited the further decline of critical pole span.Therefore solve aluminum oxide and the aluminum fluoride concentration difference becomes key.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of 700kA level electrolyzer is provided, and the alumina concentration that can reduce under the anode bottom is poor, can reduce the critical pole span of 700kA level electrolyzer, reaches energy-conservation purpose.
The technical solution of the utility model is: a kind of 700kA level electrolyzer, and the anode of 700kA level electrolyzer is parallel or vertical with the electrolyzer length direction, and anode has the interval along its length, and the interior of interval is blanking point.Totally 64 on anode is separated with 8, and width is 100～250mm, and 2～3 blanking points are arranged in the interval.Blanking point can add aluminum oxide, aluminum fluoride, ionogen etc.
The alumina concentration that the utility model has reduced under the anode bottom is poor, reduces the critical pole span of 700kA level electrolyzer, has reached energy-conservation purpose.
Description of drawings
Fig. 1 is the schematic diagram of anode when parallel with the electrolyzer length direction;
Fig. 2 is the schematic diagram of anode when vertical with the electrolyzer length direction.
