CATHODE AND ANODE BAKING APPARATUS FOR ALUMINIUM CELL Russian patent published in 2009 - IPC C25C3/10 C25C3/06 

FIELD: chemistry.

SUBSTANCE: apparatus includes several sections of L-filters made of horizontal bridge overlapping the space between the top edge of cathodic side and the gas collector, while the vertical bridge is made to overlap the space between the bottom and the gas collector. L-screen is designed as bridges thus forming two sections: underanode and side. The horizontal bridge is provided with a pool to the bottom of which the burner and prechamber inlet fitting are attached. Prechamber outlet filling is attached to the vertical bridge. The horizontal bridge along the cathodic side accommodates three collectors built, one of which serves for gas supply to the burners and the second with the attached ejector, is connected to the compressed air system. The third one serves for compressed air supply trough the auxiliary pipe to the prechamber outlet fitting, attached to the vertical bridge.

EFFECT: improved engineering-and-economical performance of the baking apparatus for aluminium cell.
